Mr. Lisa wants to hang a triangular banner at the entrance of the school. He performs an unknown dilation to include the banner labeled ∆A'B'C' on a sketch. If side A'B' is 8 units, what will be the measure of B'C' if the measure of AB is 24 feet and BC is 6 feet?
Answers
Answer:
B'C' = 2 units
Step-by-step explanation:
The dilation performed makes ∆A'B'C' (sketched flag) similar to ∆ABC (actual flag).
Given that, A'B' = 8 units, AB = 24 ft, and BC = 6 ft, therefore:
A'B'/AB = B'C'/BC
Substitute
8/24 = B'C'/6
Cross multiply
24*B'C' = 8*6
24*B'C' = 48
B'C' = 48/24
B'C' = 2 units

A diameter spans from one end of (in this case, a circle) to the direct opposite end, going through the center-point. The radius, on the other hand, is half of a diameter, and spans only from the center-point to a point on the circle.
In this case:
1) Diameter = 18 km (given)
Radius = 18/2 = 9 km
2) Diameter = 1 x 2 = 2 m
Radius = 1 m (given)
3) Diameter = 17 x 2 = 34 cm
Radius = 17 cm (given)
4) Diameter = 50 mm (given)
Radius = 50/2 = 25 mm

Solve for x:
5x - 3y = 22
10x - 4y = 46
Answers
Answer:
x=5, y=1
Step-by-step explanation:
Isolate x for 5x-3y=22
5x-3y=22
Add 3y to both sides
5x-3y+3y=22+3y
Simplify
5x=22+3y
Divide both sides by 5
5x/5=22/5+3y/5
Simplify
x=22+3y/5
Substitute x=22+3y/5
10*22+3y/5-4y=46
Simplify 10*22+3y/5-4y
10*22+3y/5=2(3y+22)
=2(3y+22)-4y
Expand 2(3y+22)
=6y+44-4y
Simplify 6y+44-4y
=2y+44
Isolate y for 2y+44=46
2y+44=46
Subtract 44 from both sides:
2y+44-44=46-44
Simplify
2y=2
Divide both sides by 2;
2y/2=2/2
Simplify;
y=1
For x=22+3*1/5 substitute y=1
y=22+3*1/5
22+3*1=25
=25/5
Divide the numbers;25/5=5
=5
x=5
The solutions to the system of equations are;
x=5, y=1
Devon build shelves in the basement to use for storage he built shelves so that they would easily hold plastic containers shaped like rectangular prisms that measures 16in by13in by 1.75feet he currently has his off-season clothing stuff in the boxes that is 1.5'feet by 1.5'feet by14"feet will all of the clothing fit into the plastic storage container so that he can put it on his new shelves
Answers
Answer:
The volume of old box storage is greater Than the volume of plastic container, hence, Devon's clothing will not fit into the plastic container.
Step-by-step explanation:
Converting inch measures to feet :
1 inch = 0.0833 feets
Volume of rectangular prism :
V = Lenght * width * height
Volume of plastic container:
16 in = 16 * 0.0833 = 1.3328 feets
13 in = 13 * 0.0833 = 1.0829 feets
Volume of plastic container :
V = 1.3328 * 1.0829 * 1.75 = 2.526 ft³
Volume of box :
1.5 * 1.5 * 14 = 31.5 ft³
The volume of old box storage is greater Than the volume of plastic container, hence, Devon's clothing will not fit into the plastic container.
Mike is catering a party. He plans on having 4 trays of 5 appetizers each on the buffet at the beginning of the party and will rotate in new trays as those become empty. To ensure that he does not run out of appetizers during the party, he is going to make 2 appetizers per person in addition to the initial number put out on the buffet. Which of the following represents A, the amount of appetizers Mike needs to make, in terms of p, the amount of people attending the party?
Answers
Answer:
A = 20 + 2p
Step-by-step explanation:
A = 4(5) + 2p
A = 20 + 2p
A = 2p + 20
A = 2(p + 10)
I’m getting the 20 from the 4 trays of 5 appetizers on the buffet. I’m getting the 2p from the “two appetizers per person”

Solution:
y =
Answers
Answer:
x = -1, y = -1.
Step-by-step explanation:
-3x +y = 2
7x – 8y = 1
We can use the elimination method to solve these:
Multiply the first equation by 8:
-24x + 8y = 16
Now add this to the second equation:
-17x -8y + 8y = 17
-17x = 17
x = -1.
Plug x = -1 into the first equation:
-3(-1) + y = 2
3 + y = 2
y = -1.
