Answer:
Number = 15.
Step-by-step explanation:
Given : If you multiply a number by 3 and then subtract 5, you will get 40.
To find : what is the number.
Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.
According to question :
Let the number = x
Multiply is with 3 = 3x
Subtract 5 from it we get 40 .
3x -5 = 40
On adding both sides by 5
3x = 45 .
On dividing both sides by 3
x = 15.
Therefore, Number = 15.
Answer:
15
Step-by-step explanation:
3×y-5=40
3y-5=40
3y=40+5
3y=45
y=45÷3
y=15
What is "A" in this problem equal to? 4/5 = 24/A. Explain your answer! *
Answer:
A = 30
Step-by-step explanation:
cross multiply to get A out from the denominator
4/5 = 24 /A
4A = 24 x 5
4A = 120
4A/4 = 120/4 divide
A = 30

Jackson went into a movie theater and bought 8 bags of popcorn and 2 candies, costing a total of $58. Cooper went into the same movie theater and bought 4 bags of popcorn and 5 candies, costing a total of $49. Write a system of equations that could be used to determine the price of each bag of popcorn and the price of each candy. Define the variables that you use to write the system.
Answer:
Jackson: 8p + 2c = 58
Cooper: 4p + 5c = 49
Step-by-step explanation:
p= popcorn
c= candies
When you write this equation, have the cost on one side of the equation and the coefficients on the other.
HELP ASAP Find the equation of a line that goes through the points (8, -9) and (-4, 15).
Answer:
Your answer is: y= -2x+7
Step-by-step explanation:
Hope this helped : )
The equation of a line that goes through the points (8, -9) and (-4, 15) is y = -2x + 7
The formula for calculating the equation of a line is expressed as y = mx+ b
m is the slope of the line
b is the y-intercept
Given the coordinate points (8, -9) and (-4, 15)
Get the slope of the line;
[tex]m =\frac{15-(-9)}{-4-8}\\m=\frac{24}{-12} \\m = -2[/tex]
Get the y-intercept of the line
Recall that y = mx + b
15 = -2(-4) + b
b = 15 - 8
b = 7
Get the required equation in the form y = mx + b
y = -2x + 7
Hence the equation of a line that goes through the points (8, -9) and (-4, 15) is y = -2x + 7

Fernando has been saving money to buy an e-book reader. A store has just marked down the price of its readers by 40%. Each reader comes with a mail-in rebate for $25. If the reader used to cost $150, what will Fernando's final price be after the markdown and rebate? The total amount off includes the markdown and rebate. What is the total amount off?
Answer:
$85Step-by-step explanation:
We are expected to solve for the amount off the reader after 40% discount and $25 refund(rebate)
Now given that the book is $150
40% of 150
=(40/100)*150
=0.4*150
=$60
The total amount off includes the markdown and rebate.
the total amount is
60+25=$85

you're correct that, since Hugo is charging Johnny $2000, so the amount invested will be 98000.

[tex]A=98000\left(1+\frac{0.06}{4}\right)^{4\cdot 15}\implies A=98000(1.015)^{60}\implies A\approx 239435.54 \\\\[-0.35em] ~\dotfill\\\\ ~~~~~~ \stackrel{\textit{\Large Hector}}{\textit{Compound Interest Earned Amount}}[/tex]

well, seems that even though Hugo is charging some Johnny, the returned amount is more than with Hector, so Johnny should give Hugo a call.
Peyton is a salesperson who sells computers at an electronics store. She makes a base pay amount of $60 per day regardless of sales and she earns a commission of 2.5% of the dollar amount of all sales that she makes. Write an equation for P,P, in terms of x, representing Peyton's total pay on a day on which she sells xx dollars worth of computers.
Answer:
Step-by-step explanation: if Peytons base pay= $60 plus she earns commission on $x (computers sold)
P= $60+ (0.025x)
You would multiply by 0.025 as this equals 2.5%

Ray QS bisects PQR and mPQR =57°
Find mPQS
Answer:
The measure of angle ∠PQS is 28.5°
Step-by-step explanation:
If a ray bisects an angle, then it divides it into two equal angles in measures and the measure of each one is half of the measure of this angle.
In our question
∵ Ray QS bisects ∠PQR
→ That means it divides it into two angles PQS and SQR
∴ m∠PQS = m∠SQR = [tex]\frac{1}{2}[/tex] m∠PQR
∵ m∠PQR = 57°
→ Multiply its measure by [tex]\frac{1}{2}[/tex] to find the measures its parts
∴ m∠PQS = [tex]\frac{1}{2}[/tex] × 57°
∴ m∠PQS = 28.5°
∴ The measure of angle ∠PQS = 28.5°

Answer: 60
Step-by-step explanation:
write down the 12 times table
12 , 24, 36, 48, 60, 72, 84, 96, 108, 120
20, 40, 60, 80, 100, 120, 140, 160, 180, 200
Now you can see that 60 is the multiple that comes up first in both of the times tables which means it is the lowest common factor.

π/6 ≈ 11/21 cubic units
Step-by-step explanation:
Use the given values in the formula for the volume of a sphere:
V = 4/3πr³
V = (4/3)(22/7)(1/2)³ = 4·22/(3·7·8) = 11/21 . . . . cubic units
We know,
[tex]{\qquad { \longrightarrow \pmb {\sf Volume_{(Sphere)} = \dfrac{4}{3} \pi {r}^{3} }}}[/tex]
Here,
Radius of the sphere is [tex] \sf\dfrac{1}{2} .[/tex] We will take the value of π as [tex] \sf\dfrac{22}{7} .[/tex]⠀
Substituting the values in the formula :
[tex] { \longrightarrow {\qquad {\sf Volume_{(Sphere)} = \dfrac{4}{3} \times \dfrac{22}{7} \times {\bigg(\dfrac{1}{2} \bigg)}^{3} }}}[/tex]
[tex] { \longrightarrow {\qquad {\sf Volume_{(Sphere)} = \dfrac{4}{3} \times \dfrac{22}{7} \times \dfrac{1}{8} }}}[/tex]
[tex]{ \longrightarrow {\qquad {\sf Volume_{(Sphere)} = \dfrac{ \cancel4}{3} \times \dfrac{22}{7} \times \dfrac{1}{ \cancel8} }}}[/tex]
[tex]{ \longrightarrow {\qquad {\sf Volume_{(Sphere)} = \dfrac{ 1}{3} \times \dfrac{22}{7} \times \dfrac{1}{ 2} }}}[/tex]
[tex]{ \longrightarrow {\qquad {\sf Volume_{(Sphere)} = \dfrac{22}{3 \times 7 \times 2} }}}[/tex]
[tex]{ \longrightarrow {\qquad {\sf Volume_{(Sphere)} = \dfrac{22}{42} }}}[/tex]
[tex]{ \longrightarrow {\qquad {\bf Volume_{(Sphere)} = \dfrac{11}{21} }}}[/tex]
⠀
Therefore,

Step-by-step explanation:
This is a 45°-45°-90° right triangle, so the length of the hypotenuse is √2 times the length of a leg. Since both legs have length 90, the hypotenuse has length 90√2. So y=90√2.
