What is perimeter and area of this object?
Answer:
Step-by-step explanation:
You have a circle with radius r = 3 ft and a 3-by-12 rectangle.
Area of circle = πr² = 9π ft²
Area of rectangle = 3 × 12 = 36 ft²
Total area = 36 + 9π ≈ 64.3 ft²
Perimeter of circle = 2πr = 6π ft
Perimeter of rectangular projections = 18 ft
Total perimeter = 6π +18 ≈ 36.8 ft

drag each expression into the correct category according to its sum or product.
Answer:
Here are the answers. Hope this helps you!
Step-by-step explanation:
11/12*9/22 = rational (as the solution is 33/88 which is in p/q form with q not equal to 0 and p and q as integers.)
√5 *8 = 8√5 = irrational
3 + √17 = irrational (sum of a rational and irrational number is always irrational)
√3*√12 = √36 = 6= rational number
π - 2π = -π = irrational (since π is irrational)
-3/8 + 3/5 = -15+24/40 = 9/40 = rational
√6/2 - 1/2 = 1/2*√6 - 1 * 1/2 = 1/2 (√6 - 1) = irrational (in this case difference is irrational and the product is clearly irrational as well).

Write the slope intercept for of the equation
Answer: y = -3/2x + 5
Step-by-step explanation:
Answer:
y= 3/2x - 5
Step-by-step explanation:
Slope intercept form is y=mx + b
1. subtract 3x from both sides -2y= -3x + 10
2. divide -2 on each value y= 3/2x - 5
3. simplify if needed (already in simplest form)

Jenna's profit for selling 38 felt ornaments is $104.50. Suppose Jenna keeps track of the number of sales (x) and profit (y) on a graph. Which statements are correct?
Answer: B and E
Step-by-step explanation: Trust me, this is correct
The equation of the graph representing Jenna's profit is -
y = 2.75x
What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Jenna's profit for selling 38 ornaments is $104.50. Suppose Jenna keeps track of the number of sales (x) and profit (y) on a graph.
Assume that the equation of the graph representing Jenna's profit is -
y = mx + c
Then, it is a basic fact that with 0 sales, $0 profit will will be there. So, the line passes through (0, 0). Hence, the y - intercept [c] = 0. Then -
slope = [m] = (104.5)/38 = 2.75
So, the equation of line would be -
y = 2.75x
Therefore, the equation of the graph representing Jenna's profit is -
y = 2.75x

The congruence theorem that can be used to
prove ABAE = ACAD is
SSS.
O ASA.
SAS.
HL.
what is the answer?
Answer:
The answer is HL which is option D.
Step-by-step explanation:
Congruent shapes have equal corresponding sides and angles.
The congruence theorem that can be used to prove is HL
[tex]\triangle BAE \cong \triangle CAD[/tex] means that, the triangles are congruent.
From the figure, we have the following congruent sides
AB and AC --- SideAE and AD --- SideBE and CE --- Side (Hypotenuse Leg)The above highlights mean that the theorem can be used to prove that the triangles are congruent is HL.
This is so, because the hypotenuse of both triangles are equal.

how do I find the percent of budget?
Answer:
First, subtract the budgeted amount from the actual expense. If this expense was over budget, then the result will be positive.
Next, divide that number by the original budgeted amount and then multiply the result by 100 to get the percentage over budget. If your expenses were lower than your budgeted amount, then this number will be negative, describing the percentage under budget.

C) equal
D) not equal
Step-by-step explanation:
The pairs of options (A), (B), and (C) of expressions came out to be equal.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations.
We want to determine if the expressions in each answer option have the same value
A. 36 divided by 3+3 and 2^2 + 2.
⇒ 36/(3+3) =36/6 =6
⇒ 2² + 2 = 4 + 2= 6.
Here, pair of expressions that came out to be equal
B. -(2/3)^2 and 4/9.
⇒ -(2/3)² = 4/9
Here, pair of expressions that came out to be equal
C. 8(-9) and - 12 - 60.
⇒ 8(-9) = -72
⇒ - 12 - 60 = -72
Here, pair of expressions that came out to be equal
D. 1+2/4 and 1 - 1/4.
⇒ 1+2/4 = 6/4
⇒ 1 - 1/4 = 3/4
Here, the pair of expressions came out to be not equal.
Thus, the pairs of options (A), (B), and (C) of expressions came out to be equal.

30 points!!!! a class of 30 students the Ratio of the numbers of boys to girls 7:8
How many girls are there in the class?
Answer:
16 girls in the class
14 boys in the class
Step-by-step explanation:
Because of the ratio of 7:8, I added 7+8.
7+8= 15
30 (the number of students in the class) divided by 15 (the sum of the ratio)
30/15= 2
I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.
Hope this helps!
