Write this word sentence as an equation. 82 is the difference of a number b and 24
Answer:
106 - 24 = 82
Step-by-step explanation:
b = 106, solve 106 - 24 and you get 82.
Hope this helped.
Answer:
b/24=82
Step-by-step explanation:
Since the difference of an equation is the outcome of division we place 82 as the answer.
Also, since 82 is greater than 24 we can assume that the variable "b" is larger than both 82 and 24.
Find the area of each figure and round to the nearest tenth if necessary
Given:
The figure of two semicircles with diameters 6 cm and 5 cm.
To find:
The area of the combined figure.
Solution:
It is given that the diameters of the semicircles are 6 cm and 5 cm so their radii are 3 cm and 2.5 cm respectively.
Area of a semicircle is:
[tex]A=\dfrac{1}{2}\pi r^2[/tex]
So, the combined area of two semicircles with radii 3 cm and 2.5 cm is:
[tex]Area=\dfrac{1}{2}\pi (3)^2+\dfrac{1}{2}\pi (2.5)^2[/tex]
[tex]Area=\dfrac{1}{2}\pi (9)+\dfrac{1}{2}\pi (6.25)[/tex]
[tex]Area=14.137167+9.817477[/tex]
[tex]Area=23.954644[/tex]
Round the value to the nearest tenth (one decimal place.
[tex]Area\approx 24.0[/tex]
Therefore, the area of given figure is 24.0 sq. cm.

Jesean buys a pizza for 20$ and 10 drinks. The drinks Cost the same amount. He spends 32$ on the pizza and the sodas together
Answer: See explanation
Step-by-step explanation:
Yiur question isn't complete but I believe that you want to know the price of the soda.
Let the price of the soda be represented by x.
Jesean buys a pizza for 20$ and 10 drinks. This will be: 20 + 10x
He spends 32$ on the pizza and the sodas together. This can be formed into an equation as:
20 + 10x = 32
10x = 32 - 20
10x = 12
x = 12/10
x = 1.2
Therefore, the soda cost $1.20 each

Let f(x)=x^2+2 and g(x)=1-3x Find each function value. f(g(-4))
Answer:
171
Step-by-step explanation:
First you plug -4 into the g(x) equation
g(-4)= 1-3(-4)
Use pemdas
g(-4)= 1+12
g(-4)= 13
Next you plug 13 into the f(x) equation
f(13)= 13^2 + 2
First you do 13^2=169
Add 2 and you get 171

Write the first six terms of the sequence, beginning with n=1. a(n)=60n Enter the numbers, separated by commas.
Answer:
60, 120, 180, 240, 300, 360
Step-by-step explanation:
a(n)=60n
At n =1
a(1) = 60(1) = 60
At n = 2
a(2) = 60(2) = 120
At n = 3
a(3) = 60(3) = 180
At n = 4
a(4) = 60(4) = 240
At n = 5
a(5) = 60(5) = 300
At n = 6
a(6) = 60(6) = 360
60, 120, 180, 240, 300, 360

Rachel makes spirit bows for game day. She uses 48 feet of ribbon for 12 bows. If she uses the same amount of ribbon for each bow, how much ribbon would she need for 10 bows?
Answer:
40 ribbon
Step-by-step explanation:
We need to idenify the ratio which is 1 bow to 4 ribbons, so we times that by ten and we get 10:40 so its 40 ribbons. (Hope it helps)
The amount of ribbon she needs for 10 bows will be 40 feet.
What will be the quantity of ribbons for 10 rows?It is given that
As she uses 48 feet of ribbon for 12 bows.
So for one bow, the ribbon will be
[tex]\dfrac{48}{12} =4[/tex]
So now if the size of the ribbon should be the same for the new 10 bows then
Size =[tex]10\times 4=40\ feet[/tex]
Thus the amount of ribbon she needs for 10 bows will be 40 feet

What is Square Root?Square root of a number is the value such that the value when multiplied to itself two times gives the original number.
It is denoted by the symbol √.
For example, square root of 16 is 4 since 4 × 4 = 16
Given expression is
√100 / √25
We have to find the square root of each of the value and then divide it.
We know that,
100 = 10 × 10
So 100 = 10²
So,√100 = 10
Similarly,
25 = 5 × 5
So √25 = 5
Substituting the values,
√100 / √25 = 10 / 5 = 2
Hence the quotient is 2.
