Question:
Miriam is making a bulletin board that is shaped like a square. She has 72 inches of border material. If x represents the length of one side of the bulletin board, which inequality model and solution set best represents the possible side lengths of Miriam's bulletin board?
Answer:
[tex]x \le 18[/tex]
Step-by-step explanation:
Given
[tex]Border\ Material = 72[/tex]
Required
Determine an inequality for x
Represent the side lengths of the border with y. So:
Since the border is on the 4 sides, then
[tex]4y = 72[/tex] -- i.e. the perimeter of the border material
Solve for y
[tex]y =\frac{72}{4}[/tex]
[tex]y =18[/tex]
Recall that x represents the board's side length.
Since x will be situated inside the boarder, then.
[tex]x \le y[/tex]
Substitute [tex]y =18[/tex]
[tex]x \le 18[/tex]

How do I do these two? I’m so confused-
Answer:
1: 58
2: 140
Step-by-step explanation:
For blank 1:
arc SU is 180, this is because its the angle of the diameter.
arc TU is 122, because its the double of angle S, so 61 times 2 is 122.
- We know that a circle is 360 degrees, so 180 + 122 is 302
-Therefore 360-302=58.
For question 5:
Arc CA is 180, because it's the angle of the perimeter
Arc BC is 40, because its the double of angle A, so 20 times 2 is 40.
- We know that a circle is 360 degrees, so 180 + 40 is 220.
- Therefore 360-220=140
Select all expressions that are equivalent to 6+18i.
Answer:

2(3+9i) , 6(1+3i)

Answer:
Step-by-step explanation:
No they are not similar triangles.
In similar triangles, corresponding side will be in same ratio.
[tex]\frac{KM}{NC}=\frac{36}{28}=\frac{9}{7}\\\\\\\frac{KL}{PN}=\frac{24}{16}=\frac{3}{4}\\\\[/tex]
Corresponding sides are not in same ratio. So these are not similar triangles

no is the power of 6
Answer:
4784 to the power of 7
Step-by-step explanation:
i'm not sure if i interpreted what you wrote correctly, but if its ((4600*1.04)to the power of 7), then my answer would be correct.
if it was 4600*1.04 (where 1.04 would be to the power of 7), then the answer would be about 6053.28618, or 4600*26 to the power of 7/ 25 to the power of 7

An animal rescue center has an adoption event. People adopt 84 animals at the event, which is 70% of the animals at the center. How many animals were at the center before the adoption event? Explain your reasoning
Answer:
120
Step-by-step explanation:
Find how many were there before the adoption event by dividing 84 by 0.7
84/0.7
= 120
So, there were 120 animals before the adoption event
Mr. Juarez opened a savings account with an initial deposit of $560 and will not make any additional deposits or withdrawals. The account earns 1% simple interest. What is the total amount that Mr. Juarez will have in his account at the end of 3 years?
Answer:
$576.80
Step-by-step explanation:
We have been given that Mr. Juárez opened a savings account with an initial deposit of $560 and will not make any additional deposits or withdrawals. The account earns 1% simple interest.
We are asked to find the total amount that Mr. Juárez will have in his account at the end of 3 years.
We will use simple interest formula to solve our given problem.
[tex]A=P (1+rt)[/tex]
A = Final amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
t = Time in years.
Let us convert 1% into decimal form,
1%=1/100=0.01
P=$560 and t=3
A=$560 (1+0.01(3))
A=$560 (1+0.03)
A= $560 (1.03)
A= $576.80
Therefore, Mr. Juárez will have $576. 80 in his account at the end of 3 years. Hope this helps!

A local hamburger shop sold a combined total of 375 hamburgers and cheeseburgers on Friday. There were 75 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Friday? hurry please lol
Answer: 225 hamburgers were sold on friday
Step-by-step explanation:
Let x represent number of hamburgers
and x-75 represent cheeseburgers
such that total hamburgers and cheeseburgers sold on Friday equaling 375 can be represented as
x + (x-75) =375
2x-75=375
2x=375+75
2x =450
x=450/2=225
Hamburgers =225
cheeseburgers= x-75=225-75=150

Jaxon built a treehouse with a base of 12 square yards. The volume of his treehouse was 108 cubic yards, how tall is the prism? Explain your answer.
Answer:
h = 9 yds, assuming his treehouse is a rectangular shape. 9 yds seems pretty high.
Step-by-step explanation:
area = bh
108 yd³ = 12 yd² x h
h = 108/12 = 9 yds
The prism is 9 yards tall
What is the Volume of Rectangular Prism?
The area occupied inside a rectangular prism is referred to as the volume of the prism. A polyhedron with two pairs of congruent and parallel bases is referred to as a rectangular prism. It has 12 sides, 6 faces (all of which are rectangles), and 8 vertices. Given that the rectangular prism is a three-dimensional (3D) shape, the units cm3, m3, and so forth are employed to express the volume of the rectangle prism. Any polyhedron that possesses all of these qualities is referred to as a cuboid in mathematics.
Given: base of the treehouse= 12 yards²
volume of the treehouse = 108 yards³
To find : how tall is the prism ( height of the treehouse) = ?
Formula Used : The volume of a rectangular prism is calculated using the formula volume of a rectangular prism (V) = l w h,
where "l" stands for base length
"w" for base width.
"h" refers to the prism's height.
Steps for calculating the height
Step 1: The foundation area of 12 square yards has previously been specified.
Step 2: The prism's volume is 108 cubic yards
Step 3: The given rectangular prism's volume = base area x height
=> 108 cubic yards = 12 x h
=> 108/ 12 = h
=> h = 9 yards
Since , the prism is 9 yards tall

Answer:
True
Step-by-step explanation:
Answer:
True
Step-by-step explanation:
Two of the radicals have the same index and radicand, so they can be combined. Rewrite the expression so that like radicals are next to each other. Combine. Although the indices of and are the same, the radicands are not—so they cannot be combined.
