Answer:
It's the 2nd one
Step-by-step explanation:
So to find the perimeter you add all the sides together. So if 2 of the sides are 20 and 15, that means the other ones are 20 and 15.
Once you add those all together you get 70.
To find the area you multiply the two different sides, so that would be 20 and 15.
20 times 15 is 300.
I hope this helps!! :)
Bradley has a coupon for 15% off the price of a computer. The sales tax is 8%.
How much money did Bradley save, including sales tax, by using his coupon?
(Total cost of the computer with sales tax and coupon is $454.41)
Answer: $31.81
Step-by-step explanation:
First figure out how much the sales tax was
454.41x0.8=36.35
Then figure out how much the coupon subtracted off the total price
454.41x0.15=68.16
Subtract 68.16 by 36.35
68.16-36.35=31.81

Part A.Maggie is making a necklace using 14 inch string and identical beads. Maggie has placed 12 beads next to each other starting at the left end of the string as shown in the figure. The 12 beads fill 3 inches of the string. How many total beads will completely fill the 13 inch string?
Part.BAfter filling the string from end to end, Maggie decides to leave one inch at each end of the string with no beads. How many beads does she need to remove from the beads she used to completely fill the string?
Answer:
a) 56 beads
b) 8 beads
Step-by-step explanation:
12 beads take 3 inches so yes 12/3 =4 per inch
but then the necklace is 14 in long so 4 *14=56 beads
if you take off one ince per side you would take of 4 beads per side so 4*2=8 beads

Answer:
2/7 divided 7= 2/14=1/7
Step-by-step explanation:
In these kind of problems you keep,change,flip
2/7 stays the same the division symbol change to a multiplaction sign and since the 7 is a whole we have to change it to 7/1 and flip it so the answer is 2/14 and since 2 goes into 14 we can simply when change to 1/7

7. Terrance needs to find the lateral surface area of the box shown below. Assuming that the base is the bottom of the prism, which of the expressions below will give him the correct lateral surface area?
The expression that will give the correct lateral surface area of the rectangular prism = (14.5 + 14.5 + 7 + 7)(8.6)
What is the Lateral Surface Area of a Rectangular Prism?The lateral surface area (LSA) = 2(l + w)h
Given the following:
l = 14.5 w = 7h = 8.6Lateral surface area of the prism = 2(l + w)h = 2(14.5 + 7)8.6
Lateral surface area of the prism = (14.5 + 14.5 + 7 + 7)(8.6)

Answer:864m^2
Step-by-step explanation:
18*18=324
18*30=540
540+324=864
Answer:
684 m.
Step-by-step explanation:
First you divide the shape into one rectangle and one square. You first multiply 18 x 18 for the square to find the area, which equals to 324. Then you do 18 x 30, as the sides are equal. this equals to 540. Now, you add up 324 and 540. You will get the total of 684.
A city has the following rule for its mayoral elections:
"Citizens under the age of 21 are not allowed to run for mayor."
Part A: Write an inequality to show the age of citizens who are allowed to run for mayor. (5 points)
Part B: Describe in words how you can show the solution to this inequality on a number line. (Be specific! Open dot or closed dot? Which direction is the arrow pointing?) (5 points
Answer:
Hi! I answered a question like this yesterday so I will help!
First let's read carefully: Write an inequality to show the age of citizens who ARE allowed to run for mayor.
Part A:
If x ≥ 21, they can vote; x is the age of the person that wants to vote!
Part B:
Mark a closed dot on 21 and an arrow pointing to the right. A closed dot means "greater than or equal to" or "less than or equal to". Marking this would mean that anybody 21 or older can vote.
Hope this helps! Mark the brainliest please!~

HELP! Two right rectangular prisms are shown below. If each prism is packed with small cubes of side length 1/4 inch how many more cubes are in prism 2
A. 42 Cubes B. 48 Cubes
C. 510 Cubes D. 720 Cubes
Answer:
First find the volume of the two rectangular prisms using the formula:
V = l · w · h
Where 'l' represents the length, 'w' the width, and 'h' the height.
Now let's find the volume of Prism 1;
V = l · w · h
V = 7/4 · 3/2 · 5/4
V = (7/4 · 3/2) · 5/4
V = 21/8 · 5/4
V = 105/32 cubic inches.
Now let's find the volume of Prism 2;
V = l · w · h
V = 5/2 · 9/4 · 2
V = (5/2 · 9/4) · 2
V = 45/8 · 2/1(make 2 to 2/1 because it makes it a bit easier)
V = 90/8 cubic inches.
Now let's find how many cubes can fit into each of these prisms.
But first, we need to find out the volume of one cube.
Remember, all sides to a cube are equal.Using the formula, V = l · w · h;
1/4 · 1/4 · 1/4
= 1/64 cubic inches is the volume of one cube.
Now we find how many cubes can fit inside each of these prisms.
Prism 1:
105/32(volume for this prism) ÷ 1/64(volume of one cube)
= 210 cubes can fit inside prism one.
Prism 2:
90/8(volume for this prism) ÷ 1/64(volume of one cube)
= 720 cubes can fit inside prism two.
Finally, let's calculate their difference:-
720 - 210
= 510 cubes.
Hence, prism 2 can hold 510 more cubes than prism 1.

Answer <3
Hello there! I'm here to help with your question!
I believe the answer is x= 6
The explanation:
9 = [tex]\frac{3}{2}[/tex] x
9 =[tex]\frac{3x}{2}[/tex]
9 = [tex]\frac{3x}{2}[/tex]
2 · 9 = · [tex]\frac{3x}{2}[/tex]
2 · 9 = 2 · [tex]\frac{3x}{2}[/tex]
2 · 9 = 3x
x = 6

I NEED HELP FAST ITS FOR A TEST (no links pls)
Part A: Explain why x = 6 makes 5x − 6 ≤ 24 true but not 5x − 6 < 24. (5 points)
Part B: What value from the set {5, 6, 7, 8, 9} makes the equation 6x + 4 = 34 true? Show your work.
Answer:
I dont know about A but the answer for B is below
Step-by-step explanation:
6x + 4 = 34 = (6x5) + 4 = 34
Answer:
Seem you are doing the same test I did! Module 7 part 2?
Anyway!
Part A: If we work through the equation 5x - 6 and substitute 6 for x then we have (5*6) - 6 = 30 - 6 = 24.
Therefore, 5x − 6 ≤ 24 is true since it means that it is equal to or less than 24.
And 5x − 6 < 24 is wrong since the equation equals 24 and is not less than 24.
Part B:
6x + 4 = 34
6x5 = 30
30+4=34
To verify: (6*5) + 4 = 34. The answer is five.
Hope this helps! Brainliest please!
