Answer:
12,435 bats
Step-by-step explanation:
We need to figure out how many bats were produced.
First let's write the equation. Cost is $28 for each bat, and we start with fixed expenses of $58,780
y=28x + 58780
We are given y, total expenses at 406,960
so 406,960 = 28x + 58780
subtract 58780 from both sides
406,960 - 58,780 = 28x
348,180 = 28x
divide both sides by 28
12,435 = x
This means they produced 12,435 bats.

Missing length?? Please help me out
Answer:
The missing length is 12
Step-by-step explanation:
Required
Determine the missing length (LS)
If RS = 28 and KS = 14
Then
[tex]KR = RS - KS[/tex]
[tex]KR = 28 - 14[/tex]
[tex]KR = 14[/tex]
The sides of the given shape are directly proportional.
This implies that:
[tex]KS : LS = RS : QS[/tex]
[tex]KS = 14[/tex]
[tex]RS = 28[/tex]
[tex]QS = 12 + LS[/tex]
[tex]LS = ??[/tex]
So, the expression becomes:
[tex]14 : LS = 28 : 12 + LS[/tex]
Represent as a fraction
[tex]\frac{14}{LS} = \frac{28}{12 + LS}[/tex]
Cross Multiply:
[tex]14(12 + LS) = 28 * LS[/tex]
Divide through by 12
[tex]12 + LS = 2 * LS[/tex]
[tex]12 + LS = 2 LS[/tex]
Collect Like Terms
[tex]2LS - LS = 12[/tex]
[tex]LS = 12[/tex]
The length of the missing side is 12

Answer/Step-by-step explanation:
If two triangles are similar, their corresponding angles would be of equal measure of degree.
8. The 3rd angle of the smaller ∆ is x = 76°, while that of the larger ∆ is y = 44°. As we can see, the corresponding angles of both ∆s are not congruent or equal to each other. Therefore they ARE NOT SIMILAR.
9. x = 43°, while y = 106°.
Both triangles have corresponding angles that are congruent to each other.
Therefore, both triangles ARE SIMILAR.
Could someone please help me with this equation, thank you.

If ABCD is a square and AC= 26, what is the length of BC
Answer:
BC = 18.385
Step-by-step explanation:
You can look at ABC as a right triangle and use the Pythagorean theorem to solve for BC. 26 squared is 676, 676 divided by 2 is 338, and finally the square root of 338 is 18.385. This is the length of BC and AB as well. Hope that helped
Answer: aprox 18.38
Step-by-step explanation:
you have a AC=, which is the hypothenuse of the right triangle, and isosceles
ABC
AB=BC, sides of a square
remember c^2=a^2+b^2 but and b are equal so we can say
c^2= 2a^2
c=a[tex]\sqrt{2}[/tex], 26/[tex]\sqrt{2}[/tex]=a
a=(26[tex]\sqrt{2}[/tex])2=18.38
The mean diastolic blood pressure for a random sample of people was millimeters of mercury. If the standard deviation of individual blood pressure readings is known to be millimeters of mercury, find a confidence interval for the true mean diastolic blood pressure of all people. Then give its lower limit and upper limit.
Answer:
(85.62, 90.38).
Step-by-step explanation:
The missing data can be assumed to be we have the following information:
¯x =88, s=10, n=70
Substituting the values in the following formula, we compute the 95% C.I for true population mean diastolic pressure as shown below:
95% C.I.=¯x±t(0.95,n−1)⋅Sm=¯x±t(0.95,70−1)⋅s√n=88±1.99⋅10√70=(85.62,90.38)
The answer is (85.62, 90.38).

A group of 4444 friends is playing cards. The deck has 70707070 cards. To start the game, the dealer makes a pile of 15151515 cards in the center. Then she deals the remaining cards one at a time to each player until all the cards are gone.
What is the greatest number of cards any player will have after all the cards are dealt?
cards
Answer:
12502 cards
Step-by-step explanation:
Given:
» total of 70707070 cards of the deck
» 15151515 cards were taken and put in a pile
Solve:
1. So, you can subtract 15151515 from 70707070 to find how many cards are left:
70707070 - 15151515 = 55555555
2. Now, there are 55555555 cards remaining in the deck since 15151515 cards were taken to put in a pile. Since the dealer deals the remaining cards to 4444 people, you can just do 55555555 divided by 4444 to find how many cards each person gets:
55555555 ÷ 4444 = 12501.25
3. 12501.25 is the exact number of cards each person gets, but you can’t have a fraction/part of a card. You have to find a specific remaining number:
0.25 is the same as [tex]\frac{1}{4}[/tex], and so convert [tex]\frac{1}{4}[/tex] into a fraction with a denominator of 4444, but is still equivalent to [tex]\frac{1}{4}[/tex]: You’ll get [tex]\frac{1111}{4444}[/tex], which is correct because it’s still equivalent to [tex]\frac{1}{4}[/tex]
4. So, the remaining 55555555 cards divided by 4444 people is 12501 cards and a remainder of 1111 cards. The 1111 cards can be distributed upon the players, but not everyone can get it. Since 12501 were to given to the players and after the remaining 1111 were also distributed, this means that some will have 12501 cards and others will have 12502 cards.
Answer: So, the greatest number of cards any player will have after all the cards are dealt is 12502 cards.

Mario is playing an online puzzle game. He has 50 points and earns 3 points
for each puzzle he solves correctly. He will advance to the intermediate level
if his score is over 80 points.
Answer:
I think there might be more to this question, but the answer I have is
3x + 50 > 80
Step-by-step explanation:
If he has 50 points, needs higher than 80 points to advance to the intermediate level and receives 3 points for every puzzle he solves correctly, he must multiply the 3 by something to add to 50 to get a total amount higher than 80. Thus, 3x + 50 > 80 is the appropriate answer. Have a good day!
Answer:
the answer is 50x + 3 >80

Step-by-step explanation:
A shoe company wants to test an updated model of a running shoe on its wear after one month of running. They recruit 50 people who run on a regular basis to participate in the study. Twenty-five runners will receive a pair of the new model and the remaining 25 will receive a pair of the current model. After one month, the wear on the shoes will be determined using the depth of the tread and the flexibility of the toe box. The wear between the new and current models will then be compared.
Which of the following describes a completely randomized design for this experiment?
The subjects are numbered 1–50 and these numbers are put into a random number generator. The first 25 random numbers, ignoring repeats, represent the subjects assigned to the new model group. The remaining 25 subjects will wear the current model.
The subjects’ names are written on equal-sized slips of paper and placed into a hat. A researcher then reaches in and pulls out 25 slips of paper. These subjects are assigned to the new model group. The remaining 25 subjects will be assigned to the current model group.
The 50 subjects are paired based on running ability. The fastest two runners are paired together, the next fastest, etc. For each pair of runners, the researcher will flip a coin. If the coin lands on heads, the first runner will receive the new model and the second runner will receive the original model.
The 50 subjects are grouped based on running ability. Twenty runners classify themselves as competitive runners and the remaining 30 classify themselves as recreational runners. For the competitive group, the runners’ names are written on equal-sized slips of paper and placed into a hat. The slips are shuffled, and the first 10 runners wear the new model and the other 10 wear the current model. The same procedure is used to assign the shoes to the recreational group.
Answer:
Option A: The subjects are numbered 1–50 and these numbers are put into a random number generator. The first 25 random numbers, ignoring repeats, represent the subjects assigned to the new model group. The remaining 25 subjects will wear the current model.
Step-by-step explanation:
We are told that Twenty - five runners will receive a pair of the new model and the remaining 25 will receive a pair of the current model.
Now, a completely randomized design is defined as one where the treatments will be assigned completely at random in such a manner that each experimental unit will posses the same chance of receiving any of the treatments given.
To this effect, the most likely answer will be picking people at random to assign either the new model or current model.
This is usually done by making a list of the treatment combinations and then assigning a random number to each subject.
Looking at the options, the most appropriate will be option A.

if a rectangle have length of 10 inches and width of 8 inches what is the new area if each corner is cut by x^2
Answer:
[tex]80 - 4x^2[/tex]
Step-by-step explanation:
Area of a rectangle
A rectangle of width W and length L has an area of:
A = W.L
The given rectangle has a length of L=10 inches and a width of W=8 inches, thus its area is:
A = 8*10 = 80
[tex]A = 80\ in^2[/tex]
If each corner is cut by a square of x*x, then the total area will be:
[tex]A' = 80 - 4x^2[/tex]
The new area is [tex]\mathbf{80 - 4x^2}[/tex] square inches
prove that cos² (45+A) + (45-A)=1
Answer:
Cos²(45°—A) + cos²(45°+A)
= [2 cos²(45°—A) + 2 cos²(45°+A)] /2
= [{2 cos²(45°—A)—1} + {2 cos²(45°+A)—1} + 2] /2
= [cos2(45°—A)+cos2(45°+A)+2]/2
= [cos(90°—2A)+cos(90°+2A)+2]/2
= (sin2A—sin2A+2)/2
= 2/2
= 1

m
The required value of x is 40 which is determined by the substitute that equals the vertical angles.
What are the vertical angles?When two lines intersect at a location, vertical angles are generated. They are always equal to each other.
As per the given accompanying diagram, lines AB and CD intersect at point E.
Since ∠AED and ∠BEC are vertical angles then they are congruent, thus
⇒ ∠AED = ∠BEC
⇒ (x + 10) = 50
Subtract 10 from both sides of the above equation,
⇒ x + 10 - 10 = 50 - 10
⇒ x = 40
Thus, the required value of x is 40.

If Adam and Simon start on bicycle trips from the same point at the same time and Adam travels east at 8mph and Simon travels south at 6mph then after 4.28 hours the distance between them is 60 miles.
What is speed?Speed is the distance an object covers in a particular time period. It can be calculated as under:
Speed=Distance/ Time.
How to calculate time?We have been given the speed of Adam and Simon as 8 mph and 6 mph and we are required to find the time taken by both to be 60 miles apart.
Time=Distance/speed
We cannot find individually but we can find the average time.
Time=60/(6+8)
=60/14
=2.28 hours
