Step-by-step explanation:
Answer:
Larger circle= 75.4
Smaller circle= 50.27
Step-by-step explanation:
Use this formula: C=2πr
Find the radius for bigger and smaller circle
The radis of the smaller is equal to: 12 - 4 =8
radius of smaller circle= 8
radius of bigger circle = 12
make an equation for one of the circles: (i chose the smaller one)
C=2π(8)
C= 16 π
C= 50.27
Now for the bigger circle
C=2π(12)
C=24π
C= 75.39
C= 75.4

Three students each examine the system of linear equations shown.

Caleb says there is exactly one solution. Jeremy says there is no solution. Kim says there are infinitely many solutions.
Answers
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Given the equation:
8x + 4y = 16 (1)
8x + 2y = 8 (2)
Solving equation 1 and 2 simultaneously gives:
x = 0, y = 4
Caleb is right because there is exactly one solution at (0, 4).
Answer:
The solution is (0, 4), and there is only one solution
Step-by-step explanation:
Let's actually solve the system if that's possible. Solving the second equation for 8x, we get 8x = 8 - 2y. Substituting this result into the first equation eliminates y:
8 - 2y + 4y = 16,
which simplifies to 2y = 8 and then y = 4.
Substituting 4 for y in the second equation yields 8x + 2(4) = 8, so we can quickly deduce that x = 0.
The solution is (0, 4), and there is only one solution

Write the word sentence as an equation. Then solve the equation.
Answers
Answer: n - 4 = -15
n = -11
Step-by-step explanation:
If -15 is the same as 4 less than n, that means that n - 4 = -15
Then you add 4 to each side of the equation to get n by itself. (-15 + 4 = -11)
That step leaves you with n = -11
Answer:
n - 4 = -15
N= -11 -11 - 4 = -15
Step-by-step explanation:
n − 4 + 4 = −15 + 4
n = −11

Hey there! Hope you are having a fantastic day!
To find the volume of a Prismatic Rectangle you must multiply all three sides together. In your case, It would be 4 x 2 x 1. Which would leave you with an answer of 8.

Answer:
. An investment account earns 2.8% simple interest.
Since investment amount increases every year linearly, therefore, the modeled situation represents a LINEAR FUNCTION.
B). The price of a stock varies by 2.8% each week.
Since price of the stock may increase or decrease every week, therefore, this situation can't be modeled by any function.
Therefore, the answer is NEITHER.
C). An investment account earns 2.8% compound interest, compounded monthly.

How do i Solve this?
Answers
Answer:
A=54.45
Step-by-step explanation:
You want to solve for the area in 2 parts. First I solved for the rectangle.
Area of a rectangle: A=lw
This means 9×3=27
Then I solved for the area of the triangle.
Area of a triangle: 1/2bh
This means 1/2(9×6.1)⇒1/2(54.9)=27.45
Then you add the area of the triangle and the areo of the rectangle together:
27.45+27=54.45

Problem situation:
Anna is at the movie theater and has $35 to spend.
She spends $9.50 on a ticket and wants to buy some snacks. Each snack costs $3.50.
How many snacks, x, can Anna buy?
Inequality that represents this situation:
9.50+3.50x≤35
Drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution.
Solution to both the inequality and the situation
Solution to the inequality only
Not a solution
Answers
Answer:
Step-by-step explanation:
Amount of money Anna has = $ 35
Money she spent on the ticket = $9.50
Money she spent on snacks = $ 3.50
Let x number of snacks, which will be the least number of snacks that Anna can buy.
transforming the situation in terms of inequality
→9.50 +3.50 x≤ 35
→9.50 -9.50+3.50 x≤35-9.50
→3.50 x≤25.50
Dividing both sides by 3.50, we get
→x≤7.3(approx)
which can't be the number of snacks, as it will be an integral value.
So, the minimum number of snacks with the given amount of money = 7
So, Anna can buy snacks(x)={x:x≤7,x=1,2,3,4,5,6,7}=At most 7.
