One of those squares is the volume of 125 so 125*3 is 375
D. 375 is the answers
Answer:
56°
Step-by-step explanation:
Using the sine ratio in the right triangle, that is
sin ? = 
= 
, then
? = 
( ) ≈ 56° ( to the nearest degree )
Let's set these two numbers as 'a' and 'b'
Now, let's set up equations based on the information known:
- the sum of the two numbers is 52 --> a + b = 52
- the difference is 28 --> a - b =28
Equations
- a + b = 52 -- equation 1
- a - b = 28 -- equation 2
Solve:
(Equation 1) + (Equation 2)
2a = 80
a = 40 -- equation 3
(Equation 3)
40 + b = 52
b = 12
So a = 40 and b = 12
Hope that helps!
add up the purchases
2(9.95) + 14.95
19.90 +14.95
34.85
now find the sales tax
34.85 * .06 =2.091 = 2.09 (round to 2 decimal places with money)
add the purchases and the sales tax to get the total amount
34.85 + 2.09
$36.94
Answer:
Since we have a 30° - 60° - 90° triangle, we can calculate any side by knowing at least one out of three:
Since the length of the hypotenuse is twice as long as the shorter leg, we have:
The length of the short leg is: 25/2 = 12.5
Since the length of the longer leg is equal to the length of the shorter leg
multiply by square root of 3 we have:
The length of the longer leg is: 12.5 × √3 ≈21.65
=> The perimeter of the triangle is: 25 + 12.5 + 21.65 = 59.15
