It took a ball 4 minutes to roll 286 feet. What was this ball's average speed, in feet per second? (round to the nearest hundredth)
Answer:
1.192 feet per second
Step-by-step explanation:
convert 4 minutes into seconds
4 times 60
240 seconds
velocity (speed)= distance divided by time
v=286/240
v=1.192

Kira owes her mom $125 and is planning to to payer back with payments $7 a week. Write an equation in slope-intercept form that models this situation.
Answer:
y = 17(7) + 6
Step-by-step explanation:
Given that:
Amount owed = $125
Payment per week = $7
Number of whole weeks to pay :
$125 / $7 = 17.85 = 17 whole weeks
$125 - (17 * 7) = $125 - $119 = $6
Using slope intercept notation :
y = mx + c
Where m = slope ; c = intercept. ;
m = 17,; x = $7, c = $6
y = 17(7) + 6

Tominka use 6 1/9 inches of wire to make a necklace and 3 1/3 of wire to make a bracelet. How many necklaces and bracelet sets can she make if she uses 28 1/3 inches of wire in all?
Answer: 3 necklaces and bracelet sets can be made from the 28 1/3 inches of wire.
Step-by-step explanation:
step 1
LET I set of necklace and bracelet be represented as ( A bracelet and a necklace)
if Tominka uses 6 1/9 inches of wire to make a necklace and 3 1/3 of wire to make a bracelet for a set
Then Total Length of wire that can be used for a set = 6 1/9 inches+ 3 1/3 inches = 9 (1+ 3)/9
= 9 4/9 inches.
Step 2
IF a set (One necklace and bracelet) can use = 9 4/9 inches
and Total wire used = 28 1/3inches
Then Number of necklaces and bracelet sets that can be made from the 28 1/3 inches wire = 28 1/3inches /9 4/9 inches
=85/3 / 85/ 9 = 85/3 x 9/ 85 = ( 85 cancels 85 )
9/3 = 3
3 necklaces and bracelet sets can be made from the 28 1/3 inches of wire.
Which question can be answered by finding 3 1/2÷1/4
A.You have 3 1/2 meters of ribbon and use 1/4 meter. How much ribbon is remaining?
B.How much is 1/4 of a 3/1/2-meter long piece of ribbon?
C.How many 1/4-meter long pieces of ribbon are needed to have a total of 3 1/2 meters of ribbon?
Answer: Choice C.
How many 1/4-meter long pieces of ribbon are needed to have a total of 3 1/2 meters of ribbon.
==========================================================
Explanation:
Let's consider a similar problem without the fractions.
Let's say you want to know how many 2 meter lengths of ribbon you can cut from an overall length of 24 meters. That would be 24 ÷ 2 = 12 pieces total.
So we divide the two values (large ÷ small)
The same idea applies to this problem as well. The larger amount (3 & 1/2 meters) is what we cut up, and each slice is 1/4 of a meter. To find the number of pieces, we would compute 3 1/2÷1/4
Note: it might help to convert the mixed number 3 & 1/2 to the improper fraction 7/2

Michelle, lori, and patti buy lunch together. The total bill was $45. If michelle pays 35% of the total bill and lori pays 48% of the bill, how much of the total bill will patti pay
Answer:
17% of the bill
Step-by-step explanation:
Well to find the answer to this question we first have to add 35 + 48 to get the total percent of the bill that Michelle and Lori paid.
35 + 48 = 83%
now that we know the percent of the bill that Lori and Michelle are paying we have to subtract that amount by 100% to get the percent of the bill that Patti is paying.
100% - 83% = 17%
So Patti is paying 17% of the bill
If we wanted to go even farther and find out what 17% of the bill was all we would have to do is multiply 45 by 17% or 45 x 0.17
45 x 0.17 = 7.65
So Patti is paying 7 dollars and 65 cents

Find the length of AC.
a. 10.1
b. 10.0
c. 10.9
d. 8.86
PLEASE HELPPP ASAP
Answer:
Option D
Step-by-step explanation:
According to law of cosines =
[tex] {a}^{2} = {b}^{2} + {c}^{2} - 2bc. \cos(A) [/tex]
where 'a' is the uknown side , 'b' & 'c' are the given sides and angleA is the angle opposite to the uknown side i.e. opposite to 'a'.
Using the Law of cosines , we'll find the length of AC .
[tex] {ac}^{2} = {7}^{2} + {13}^{2} - 2 \times 7 \times 13 \times \cos(50) [/tex]
[tex] = > {ac}^{2} = 49 + 169 - 182 \times 0.76[/tex]
[tex] = > {ac}^{2} = 218 - 138.8 = 79.68[/tex]
[tex] = > ac = \sqrt{79.68} = 8.92 = 9(appx)[/tex]
In option D , if we'll round of 8.86 , then its appx 9. So option D is right

The United States Air Force has 19 women for every 81 men enlisted. If a squadron has 750 memebers, approximately how many are women?
Answer:here are approximately 143 women
Step-by-step explanation:
Step 1
Given that for every 19 women, there are 81 men in the United States Air Force therefore we can say the ratio between the men and women is given as 81:19
such that the fraction to represent men = ratio of men/ total ratio of men and women
81/(19 + 81)= 81/ 100 =0.81
and the fraction to represent women = ratio of women/ total ratio of men and women
19/(19 + 81)= 19/ 100 = 0.19
Step 2-
To calculate the number of men in a 750 squadron, we have that
fraction of men x number of members
=0.81 x 750= 607.5 ≈ 608
To calculate the number of women in a 750 squadron, we have that
fracton of women x number of members
=0.19 x 750= 142.5 ≈ 143
Therefore there are approximately 143 women .
The relationship (3,2)(2,5) (8,5) (3,6) is a function
A True
B) False
Answer:
I would say it's B. false
Answer:
False
Step-by-step explanation:
Look at the inputs (x-values)
If the inputs are the same, the relationship is Not a function.
Inputs (x-values), cannot share the same output (y-values).
Example:
Inputs Outputs
3 2
2 5
8 5
3 6
In the input there are two 3's which causes this to not be a function.
(Outputs can have the same numbers repeating just not inputs.)

Answer:
the middle one because HL is hypotenuse-leg and the middle one is the one that has a congruent hypotenuse and a congruent leg
(HL theorem only works with a right triangle)
Step-by-step explanation:
The pair of triangles that can be proven congruent by the HL theorem is the triangles in the middle.
Calculations and ParametersAccording to the HL Theorem:
A triangle would contain:
A hypotenuse-legCongruent hypotenuseCongruent leg.Therefore, we can see that the pair of triangles in the middle of the diagram are congruent through the HL theorem as they satisfy the conditions.

The students in Ms. Douglas’ class worked so hard this year that she has planned a surprise, end-of -year trip for them to a local amusement park. The school principal allows Ms. Douglas to spend a budget of $500 on the trip.
So far she knows : A coach bus costs $180 to transport them to and from the park Price of admission to the park is $15 per person
Part A : Write an inequality that describes that how many students Ms. Douglas can bring on the trip. Define the variable
Part B: Solve the inequality and explain the solution in the context o the problem
Answer:
A) 180+15x=500
B) 21 people.
Step-by-step explanation:
$180
so 500-180 is 320.
320/15 is 21 1/3
So, Ms. Douglas can take 20 students and herself :)
Part A:
180+15x=500
180-180+15x=500
15x=320
x=21 1/3, so Ms. Douglas can afford to take 21 people,, but one of them is herself.
Hope this helps pls hit the crown :D
Answer:
A. 500 = 180 + 15x
So Ms.Douglas has a budget of $500 and she is going to spend $180 going to and from school on a bus. 180 is your constant. It is $15 per person to enter the gate of the amusement park and 15 is your variable.
So 500 = 180 +15x
Step-by-step explanation:
B. 500 = 180 + 15x
320 = 15x
x = 21.333333
but since we are talking about people here Ms.Douglas can only take 21 people

domain: {–2, 0, 2}, range: {4, 0}
d.
domain: {–2, 0, 2}, range: {4, 0, 4}
Answer:
C
Step-by-step explanation:
The domain of the given function is {–2, 0, 2} while range is {4, 0} so option (C) will be correct.
What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
Given the function,
An arrow goes from negative 2 to 4, 0 to 0, and 2 to 4.
So,
-2 → 4 , 0 → 0 and 2 → 4
Since the domain is a set of input values here input is -2,0 and 2.
So
Domain = {-2,0,2}
And the range is a set of output values here output is 4, 0
So,
Range = {4,0}
Hence "The domain of the given function is {–2, 0, 2} while range is {4, 0}".

Step-by-step explanation:
Using the located points (-1,4) and (4,-4) we will find the difference in the y coordinates of the points and divide it by the difference in the x coordinates of the same points.
Difference in y: 4 - (-4) = 8
