H x sin55 =10.4
÷sin55
H= 10.4/sin55
H=12.7cm

Step-by-step explanation:
Answer:
24
Step-by-step explanation:
The cake measures 10 inches by 15 inches. If pieces are 2.5 inches long and wide (they are square and equal) then 6 pieces will be cut along the length.
15/ 2.5 = 6
And 4 pieces will be cut along the width.
10/ 2.5 = 4
All together when the entire cake is cut, there will be 4*6 = 24 squares 2.5 inch long pieces.
The unit rate of gas usage is 35 miles per gallon.
Step-by-step explanation:
"Unit rate" refers to the number of miles for 1 gallon.
<u>From the graph given</u>,
it can be determined that, the car goes 2 miles for 70 gallons and 3 miles for 105 gallons.
To find miles per gallon, <u>use rate formula</u>
Rate= <em>Given miles/ Given gallons</em>= 2/70
Unit Rate= <em>miles/ 1 gallon</em>= X/1
where "X" term refers to number of miles per gallon.
By Comparing the rates we get,
2/70 =X/1
<u>X=35 miles per gallon</u>
Similarly,
3/105 =X/1
<u>X=35 miles per gallon</u>
The common factors are 1 and 5.
