Solution:
Please help fast I will give brainliest! :)
He should ride 11 miles on each of the other 5 days. 11 times 5 equals 55 + 25 = 80.
Tyrese wants to buy 15 packs of baseball cards. They cost $ 5.00 per pack. There is a 25 % discount before tax if 10 or more packs are purchased. Sales tax is 7 % . Tyrese gives the cashier $ 100 to pay for his baseball cards. How much change will he receive in return?
Answer:
Tyrese will receive $39.81 in return.
Step-by-step explanation:
First, you have to multiply the 15 packs for the cost per pack:
15*$5=$75
As there is a 25% discount before tax if 10 or more packs are purchased, you have to calculate 25% of the total cost for the 15 packs and subtract that amount from the cost:
$75*25%=$18.75
$75-$18.75=$56.25
Then, you have to calculate 7% of the amount with the discount and add that to the cost:
$56.25*7%=$3.93
$56.25+$3.94=$60.19
Now, you can subtract $60.19 from $100 to find the change that Tyrese will receive in return:
$100-$60.19= $39.81
According to this, the answer is that Tyrese will receive $39.81 in return.
Solve for x
Y= x-v/b
Answer:
x=y+v/b
Step-by-step explanation:
So first you have y=x-v/b. You want to isolate x, so subtract x from both sides. You'll get -x+y=-v/b. Next, you're going to want to subtract y to further isolate x now that it's on the left side. Now you'll have -x=-y-v/b. But you don't want x to be negative, so you can divide both sides by -1 to make x positive. Now you'll have x=y+v/b.
Which angle is coterminal with a 635° angle?
A. An angle measuring 85°
B. An angle measuring 275°
C. An angle measuring 255°
D. An angle measuring 335°
Answer:
B.
Step-by-step explanation:
the answer is B bevause you subtract 635 and 360, and then you get 275.
An angle measuring 275° is coterminal with a 635° angle.
What is Coterminal angles?This classification represents angles that do not present the same value, but they present vertices and sides are identical. Also, if the angles are coterminal, then their sines, cosines and tangents are equal.
here, we have,
we know that,
A coterminal angle can be found from the formula β = α ± 360 * w, where w is a positive integer.
Thus,
For w=1 and α=635°
β = 635° ± 360 * 1
β = 635° ± 360
Then, β can be 635°+360=995° or 635°-360= 275°
For w=2 and α=635°°
β = 635° ± 360 * 2
β = 635° ± 720
Then, β can be 635°+720=1355° or 635°-720= -85°
Therefore, the answer to this question is option B.

Edals of Petals, a bike manufacturer that makes flower-themed bikes, has a fixed cost of $100,000 due to the equipment necessary to make the bicycles. Additionally, each bike costs $100 in labor and materials to make. If each bike sells for $300, how many bikes must be sold in order for the company to break even?
Given:
Fixed cost = $100,000
Additional cost = $100 on each bike
Selling price = $300 each bike
To find:
The number of bikes that must be sold in order for the company to break even.
Solution:
Let x be the number of bikes.
Additional cost of 1 bike = $100
Additional cost of x bikes = $100x
So, the cost function is
Total cost = Fixed cost + Additional cost
[tex]C(x)=100000+100x[/tex]
Selling price of 1 bike = $300
Selling price of x bikes = $300x
So, the revenue function is
[tex]R(x)=300x[/tex]
At break even, the profit is zero. It other words, cost and revenue are equal.
[tex]C(x)=R(x)[/tex]
[tex]100000+100x=300x[/tex]
[tex]100000=300x-100x[/tex]
[tex]100000=200x[/tex]
[tex]\dfrac{100000}{200}=x[/tex]
[tex]500=x[/tex]
Therefore, 500 bikes must be sold in order for the company to break even.

pls help how to slove this
Answer:
a° = 124°
Step-by-step explanation:
Angle E + 250° = 360 because they make a full angle
a° + 126° + E = 360°
a° = 360 - 126 - 110
a° = 124°
Answer:
a=125°
Step-by-step explanation:
The angle at E=360-250=110°
Draw a horizontal through E, parallel to AB and CD such that it divides angle E into two angles of 55° each. Produce line AB to M such that the 55° at E is alternate with it.
A and 55° are now supplementary angles therefore
a+55°=180°
a=180-55=125°

If b=24 and c=10 what is for the missing side a= ? by Use the Pythagorean Theorem to find.
Answer:
a = 26
a ~ 21.8
Read explanation
Step-by-step explanation:
There are two possibilities;
[tex]a^{2}+c^{2}=b^{2}[/tex]
Or
[tex]b^{2}+c^{2}=a^{2}[/tex]
This is because one doesn't know the longest side, and hence there are two possibilities as to what the longest side is.
1. [tex]a^{2}+c^{2}=b^{2}[/tex]
Substitute in the given values;
[tex]a^{2}+(10)^{2}=(24)^{2}[/tex]
[tex]a^{2}+100=576[/tex]
[tex]a^{2}=476[/tex]
a=[tex]\sqrt{476}[/tex]
a~21.8
2.[tex]b^{2}+c^{2}=a^{2}[/tex]
Substitute in the given values;
[tex](24)^{2}+(10)^{2}=a^{2}[/tex]
[tex]576+100=a^{2}[/tex]
[tex]676=a^{2}[/tex]

A collector has 100 movie posters and 80 band posters. She wants to sell 30 movie posters but still have her poster collection maintain the same ratio of 100:80. If she sells 30 movie posters, how many band posters should she sell? Complete the explanation to find out how many band posters she should sell.
Answer: 24 band posters should be sold
Step-by-step explanation:
First take the expression down to its simplest form;
= 5:4
Assume she sells 30 movie posters, her movies posters drop to;
= 100 - 30
= 70 movie posters
We need a number of band posters remaining that will give a ratio of 5:4 with movie posters.
In fraction form, the number of movie posters is;
= 5/9 because 9 would be the total number of both movie posters and band posters.
Create an expression to find the total number of posters if 70 are movie posters;
5/9x = 70
x = 70 ÷ 5/9
x = 126 posters
Number of band posters that should be left are;
= 126 - 70
= 56
Number of band posters that should be sold;
= 80 - 56
= 24 posters
The new ratio would be 70:56.

Dimas is playing a game that uses a number cube. The sides of the cube are labeled from 1 to 6. Dimas wants to roll a 2 or 3. He rolls the number cube one time
Answer:
B. 1/3
Step-by-step explanation:
The total number of sides in the cube are 6 (1,2,3,4,5,6). If Dimas only wants to roll either a 2 or 3 then that would mean that he has 2 chances out of the total 6 probable outcomes to roll one of those numbers. Therefore, in order to find the probability of this happening in a single roll we need to divide the number of times that his two choices appear on the dice by the total number of sides the dice has, like so...
2 / 6 = x

3.6 - 2 - 3 = 4x - 8
please helppp
Answer:
x=1.65
Step-by-step explanation:
First switch sides
4x-8=3.6-2-3
Then subtract 3.6 - 2 - 3
4x-8=-1.4
Add 8 to both sides
4x-8+8=-1.4+8
simplify
4x=6.6
Divide both sides by 4
4x/4 - 6.6/4
The simplify again
x=1.65

A simple interest of Ghc 37,500.00 is earned on an amount of Ghc 500,000.00 for three years. Find the rate of interest per annum?
Answer:
2.5%
Step-by-step explanation:
A simple interest of Ghc 37,500.00 is earned on an amount of Ghc 500,000.00 for three years. Find the rate of interest per annum?
The formula for Rate of Interest in a simple interest is given as:
r = (1/t)(A/P - 1)
Where
t = time in years = 3 years
P = Principal = Initial amount invested = Ghc 500,000.00
A = Amount after t years =
Principal + Simple Interest
= Ghc 500,000.00 + Ghc 37,500.00
= Ghc 537,500.00
Hence:
The rate of interest = (1/3) × (Ghc 537,500.00/Ghc 500,000.00 - 1)
= r = 0.025
Converting r decimal to R a percentage
R = 0.025 × 100 = 2.5%/year
Therefore, the rate of interest per annum is 2.5%
The equation

ax−2
is true for all values of x≠2/a
where a is a constant.
What is the value of a?
A) -16
B) -3
C) 3
D) 16
Answer:
Either A or C I think, Good luck!!!
Step-by-step explanation:
Answer:
Its B
Step-by-step explanation:
24x2+25x−47=(−8x−3)(ax−2)−53
then multiply (−8x−3) and (ax−2) using FOIL.
24x2+25x−47=−8ax2−3ax+16x+6−53
Then, reduce the right side of the equation
24x2+25x−47=−8ax2−3ax+16x−47
Since the coefficients of the x2-term have to be equal on both sides of the equation, −8a=24, or a=−3.
The final answer is B.

In a survey, 27% of the people chose salads over a meat dish. In all, 81 people chose salads. How many people were in the survey?
Answer:
300
Step-by-step explanation:
Let x be the number of people in the survey
81/x = 27%
81/x = 0.27
x = 81/0.27
x = 300
Which of the following represents the relationship between the circumference, c, and diameter, d, of any circle?
Given:
Circumference of a circle = C
Diameter of a circle = d
To find:
The relationship between the circumference, c, and diameter, d, of any circle.
Solution:
We know that, circumference of a circle is
[tex]C=2\pi r[/tex]
It can be written as
[tex]C=(2r)\pi [/tex]
[tex]C=d\pi [/tex] [tex][\because d=2r][/tex]
On dividing both sides by d, we get
[tex]\dfrac{C}{d}=\pi [/tex]
Therefore, the correct option is (F).
