2. rectangle with length (x+3) and width 7
3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle?
Answer:
1= Perimeter =9.6
Area = 5.76m^2
Answer:
find the perimeter and area:
1. square with a side 2.4 m in length find the perimeter and area
answer:
length [l]=2.4m
area of square=l²=2.4²=5.76m²
perimeter of square=4l=4×2.4=9.6m
2. rectangle with length (x+3) and width 7
answer:
length [l]=x+3
Breadth [b]=7
perimeter of rectangle =2{l+b}=2(x+3+7)=2x+20
area of rectangle=l×b=(x+3)×7=7x+21
3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle.
answer:
the term for the perimeter of a circle=2πr (when radius is given ) and πd (when diameter Is given)

[46664792)
Answer:
31°
Step-by-step explanation:
The angle 59° will be equal to the angle c in triangle ABC.
Angle B will be 90°
Angle A + Angle B + Angle C = 180° (ASP)
Angle A + 90° + 59 ° = 180 °
Angle A = 180° - 90° - 59°
Angle A = 31°
Angle A = x
31° = x

9
Answer: 9
Step-by-step explanation: First, you find how many parts are needed. 4+3+1=8
So, we then divide 24 by 8 to find out what one part is. This is 3
As she needs 3 parts of parsley, we multiply 3 by 3 (each part) to get 9 tbsp.
Fabiola's special seasoning mix of 24 tbsp. needs 9 tbsp. of parsley.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Fabiola's special seasoning mix has three ingredients. The recipe uses 4 parts thyme, 3 parts parsley, and 1 part green onion.
Let, 'x' be the ratio multiplier.
Therefore, 4x + 3x + x = 24.
8x = 24.
x = 3.

Mia deposited $2,500 in an account that earned simple interest annually. She did not make additional deposits; she did not make withdrawals.
At the end of 6 years, the balance was $3,025. What is the interest rate on this account?
The interest rate on Mia's account is 20.17%.
What is the simple interest?The borrowing amount is just the principal amount multiplied by the simple interest rate.
Given, Mia deposited $2,500 in an account that earned simple interest annually. She did not make additional deposits; she did not make withdrawals.
The formula to calculate the simple interest is;
S.I. = P x T x R / 100 ,
Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.
We have, P = $2500 T = 6 years, S.I. = $3025
Substituting all the values in the formula;
3025 = 2500 x 6 x R / 100
R = 3025 x 100 / 15000
R = 20.17%
Therefore, the interest rate is 20.17%.

Solve for X. 2y-4x=10
Answer:
y = 5 + 2x
Step-by-step explanation:
Simplifying
2y = 4x + 10
Reorder the terms:
2y = 10 + 4x
Solving
2y = 10 + 4x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '2'.
y = 5 + 2x
Simplifying
y = 5 + 2x

Julie takes her kids to a playground that has the shape shown. A. While her kids are playing, Julie wants to get some exercise. If she does 2 laps around the playground, how much distance has she covered? B. The park service is creating a flyer for the playground and wants to list the area that the playground covers. How much area does the playground cover?
Answer:
a.) Total distance Julie cover = 128 feet
b.) Total area , the playground cover = 256 ft²
Step-by-step explanation:
P. S : The exact question is -
As given,
Length of 1 side = 16 feet
As , we have
4 sides of same length
⇒ Total length of playground = 16 + 16 + 16 + 16 = 16(4) = 64 feet
a.)
As given Julie does 2 lap of the playground
⇒ Total distance Julie cover = 64 + 64 = 128 feet
b.)
As the playground has equal side, so it must be of square shape
And, we know
Area of square = (Length of one side)²
= ( 16 )² = 256 ft²
∴ we get
Total area , the playground cover = 256 ft²

Yes; there is only one range value for each domain value.
No; a domain value has two range values.
No; a range value has two domain values.
Answer:
Yes; there is only one range value for each domain value.
Step-by-step explanation:
For a relation to be a function, every input, x-value, needs to have a unique output, y-value. This means that one x-value cannot have multiple y-values. So, in a function x-values will never repeat. Since x-values do not repeat in this relation, it is a function.
