To find the area you would had to do a an triangle formula so the final answer would be 63 inches
Answer:
Mrs. Cook has to grade 63 tests.
Step-by-step explanation:
In order to find the answer, first you have to calculate 80% of the number of tests Ms. Morris has:
35*80%= 28
Then, you have to add the number that represents 80% to the number of tests Ms. Morris has to grade:
35+28=63
According to this, the answer is that Mrs. Cook has to grade 63 tests.
Answer:
a = 7, b = 
Step-by-step explanation:
Using the sine ratio in the left right triangle and the exact value
sin45° = 
, then
sin45° = 
= 
= ( cross- multiply )
a × 
= 7 ( divide both sides by )
a = 7
--------------------------------------------------------
Using the tangent ratio in the right triangle on the right and the exact value
tan60° = 
, then
tan60° = 
= 
= 
= ( multiply both sides by b )
b × = 7 ( divide both sides by )
b = 
× 
=
First we divide 102 by 12.75 to get the hours which is 8 hours. So it would take 8 hours
Answer:
W
Step-by-step explanation:
On the venn diagram, you can see that everything in the W section is a multiple of 7. Everything in the Z section is an even number and everything in Y(the middle section) is both an even number and a multiple of 7. Since 49 is a multiple of 7 but not an even number, it would go in the W section.
