<span>To find out what percent 7 out of 20 is, we
need to ask: 7 out of 20 is how many out of 100? 5 groups of 20 make
100, so 7 out of 20 is 35 out of 100 (5 x 7 out of 5 x 20). Therefore 7/20 equals 35%, or 0.35 if we represent it as a decimal. I hope this helps</span>
Answer:
112 inches
Step-by-step explanation:
First since we are dealing with scale factor here you are going to want to divide the 48 by 3 since they are both written with yards.
After dividing you will get 16. This is how times you are going to multiply scale factor by. You then multiply 16 by 7 to get 112 inches as your answer.
Answer:
Step-by-step explanation:
trg CDE ,<C=<E=(180-20)/2=80
trg ABC,<C=80
<A=180-(80+52)=180-132=48
so <F=<A=48 grades
Answer:
5/12 is smaller than 6/8
Step-by-step explanation:
5/12<6/8
Answer:
9
Step-by-step explanation:
If the sine of an angle is equal to the cosine of an angle, that means that the sides adjacent and opposite to that angle are equal. One triangle that has two equal sides is an isosceles triangle. We can set this triangle to be a 45-45-90 degree triangle, which means that the angle would be 45.
Now, we have to find the value of
and
The tangent of 45 is 1, so 1 squared times 4 is 4.
We have 
.
Again, the tangent of 45 is 1, and 1 times 5 is 5.
We have 
5 + 4 = 9
