Answer:
D. ∆ABC ~ ∆DEF
Step-by-step explanation:
The triangles given shows that the three corresponding angles of both triangles are congruent to each other. This means that they have the same shape but different size.
Triangles that are congruent to each other have the same shape and the same size while triangles that have the same shape but different size are similar to each other.
Therefore, ∆ABC is similar to ∆DEF (∆ABC ~ ∆DEF).
An Native American tepee is conical tent. Find the number of skins needed to cover a teepee 10ft in diameter and 12ft high. each skin covers 15 sq. feet (use pi=3.14)
Answers
Answer:
19 skins
Step-by-step explanation:
Total surface area of the cone = πr(r+l)
r is the radius = 10ft/2 = 5ft
l is the slant height
l^2 = 12^2 + 5^2
l^2 = 144+25
l^2 = 169
l = 13ft
Get the surface area
TSA = 3.14(5)(5+13)
TSA = 15.7*18
TSA = 282.6 ft^2
If each skin covers 15 sq. feet
Number of skin needed = 282.6 /15
Number of skin needed = 18.84
Number of skin needed is approximately 19 skins

13x + 2 = 41
a. List the steps to form 13x +2.
b. List the steps to solve 13x + 2 = 41.
Answers
Answer:
Step-by-step explanation:
There isn't an exact answer for the first one since there are no like terms. But the steps to get 13x + 2= 41.
You'd have to find x.
In order to find x, you'll need to subtract 2 on both sides
13x + 2 = 41
- 2 = - 2
You'll end up with:
13x = 41
Next step is to divide 13 on both sides.
13x/ 13 = 41/ 13
So, x = 41/ 13
Or simplified to 3.153

Angela is helping her father paint a fence. She can paint 3 sections of the fence in 25 minutes. How many minutes will it take Angela to paint 12 sections of this fence?
Answers
Answer:
100 Minutes.
Step-by-step explain:
25 divided by 3 = 8.33333333333, So, 8.3 minutes to paint one section at a time. So, 8.3 x 12 = 99.6. So, 99.6 rounded since the last number is higher than 5 it would go to the next number. So, rounded its 100 minutes. 100 minutes for Angela to paint 12 sections.

The quotient of a number g and -4 is at most 5 .
Answers
Answer:
g≥-20
Step-by-step explanation:
The quotient of a number g and -4 is expressed as;
g/-4
If the quotient of a number g and -4 is at most 5, this is expressed as;
g/-4 ≤ 5
Multiply both sides by -4
g/-4 * -4 ≤ 5 * -4
g * ≥ -20
Hence the required solution is g≥-20

what is greater ar right angle or acute angle
Answers
Answer:
Right angle
Step-by-step explanation:
Given
Right angle and Acute angle
Required
Which is greater
An acute angle has its angles less than 90 degrees while a right angle has its angle to be exactly 90 degrees
Take for instance:
[tex]Acute\ Angle = 80[/tex]
[tex]Right\ Angle = 90[/tex]
By comparison: 90 > 80
So, right angle is greater.

The area of each triangle is 70
The area of the kite is 140
Answers
Answer:
Area of each triangle is 70 cm²
The total area of the kite is 140 cm²
Step-by-step explanation:
Since the kite is broken into two congruent triangles, therefore:
Total area of the Kite = 2 × area of each triangle
✔️Area of each triangle = ½*base*height
base = 20 m
height = 7 m
Area of each triangle = ½*20*7 = 70 cm²
✔️Total area of the kite = 2(70) = 140 cm²
