Answer:
39.2m
Step-by-step explanation:
The ratio would be 14/20 which is 0.7. So, you would take 56 and multipy it by 0.7 to get 39.2.
Answer:
39.2
Step-by-step explanation:
ok so you are given 2 triangles that are proportional
the 20 m side and the 56 m side go together
so this leaves 14 and L
so the ration is 2.8
multiply 14 by 2.8 and you get 39.2

Select all relations that represent function
Answer: All of the them except for the last relation.
Step-by-step explanation: For a relation to be a function, it can have y-values repeat but not x-values. In the last relation, you have (6,-6,), (-3,12), (6,-1), (-8,13). Notice that the x-value of 6 repeats 2 times in this relation. You can graph this relation and use the vertical line test and you will notice that it will touch the graph more than one time. Therefore, relations 1-4 represents functions and relation 5 does not.
Hope this explanation helps.

[tex]\sqrt{12}\sqrt{12}=12[/tex]
[tex]=12[/tex]
The value of [tex]\sqrt{12} * \sqrt{12}[/tex] is equal to 12
To solve this problem, we have to convert the surds to radicals and then use the law of indices on this.
[tex]\sqrt{12} * \sqrt{12}= 12^\frac{1}{2} * 12^\frac{1}{2}[/tex]
Addition Law of IndicesThis law is given as
[tex]a^m+a^n = a^(^m^+^n^)[/tex]
let's substitute the values in this question.
[tex]12^\frac{1}{2}*12^\frac{1}{2}[/tex]
Let's apply the law and solve the radical
[tex]12^\frac{1}{2}*12^\frac{1}{2} = 12^(^\frac{1}{2}^+^\frac{1}{2}^)\\[/tex]
Solve the fractions
[tex]\frac{1}{2}+\frac{1}{2}=1[/tex]
substitute the values and solve
[tex]12^\frac{1}{1}=12[/tex]
from the calculations above, the value of the radical is 12.

Answer:
The second one. 30 minutes ÷ 6 miles.
Step-by-step explanation:
You want to find how long it took Jamaal to run one mile.
30 minutes ÷ 6 miles = 5 minutes.
So Jamaal can run one mile in 5 minutes.

A pet store holds training classes for dogs. The store has two different training programs. The first program charges a $35 membership fee and $5 for each class. The second program does not have a membership fee, but charges $10 for each class. For how many classes will the programs cost the same? If the variable c represents the number of classes, what is the other variable for the scenario? d, representing the number of dogs in each class h, representing the number of hours p, representing the number of programs t, representing the total cost.
Answer:
7?
Step-by-step explanation:
The programs cost the same for 7 classes.
Given, no. of classes is represented by c, no. of dogs is represented by d, no. of hours is represented by h, the no. of programs is represented by p and the total cost is represented by t.
The first program charges $35 membership fee and $5 for each class.
The second program charges only $10 for each class.
Now the total cost say [tex]t_{1}[/tex], for first program can be written in equation form as,
[tex]t_{1} =35+5c[/tex], here c is the no. of classes.
Similarly, the total cost say [tex]t_{2}[/tex] , for second program can be written in equation form as,
[tex]t_{2} =10c[/tex].
We have to find out the no. of classes for which the two programs cost the same.
according to the question,
[tex]t_{1} =t_{2}[/tex]
[tex]35+5c=10c\\10c-5c=35\\5c=35\\c=7[/tex]
Hence for 7 of classes the programs cost the same.

Bianca calculated the height of the equilateral triangle with side lengths of 10.
tangent (30) = StartFraction 5 Over h EndFraction An equilateral triangle with side lengths of 10 is shown. A bisector is drawn to split the side into 2 equal parts and splits the angle into 2 30 degree segments.
Then, she used the formula for area of a triangle to approximate its area, as shown below.
A = one-half b h. = one-half (10) (8.7). = 43.5 units squared.
Calculate the area of the equilateral triangle using the formula for area of a regular polygon, and compare it to Bianca’s answer.
The apothem, rounded to the nearest tenth, is
