Answer:
10
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2 + b^2 = c^2
8^2 + 6^2 = c^2
64+36 = c^2
100 = c^2
Take the square root of each side
sqrt(100) = sqrt(c^2)
10 = c
Answer:
The x coordinate is 2

<h3>What are the
simplified mathematical expressions ?</h3>
Scientific notation is used to simplify large numbers in smaller numbers. In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
(8.6 x 
) . (9.1 x 
)
= (8.6 x 9.1) x 
= 78.26 x
= 7.8 x 10
(6.9 x 
) . (4.8 x )
= 33.12 x 
3.3 x
(3.7 x 
) . (4.6 x ) ÷ (1.4 x 
) . (5.7 x 
)
= 1.7 x 10 ÷ 8 x10²
0.21 x 
2.1 x
(3.1 x ) . (5.3 x 
) ÷ (7.3 x ) . (6.1 x 
) = 3.7

Answer:
16 lb of fresh coffee.
Step-by-step explanation:
Let x pound be the amount of fresh coffee needed.
100 - 12 = 88% is equivalent to 14 2/25 of roasted coffee.
By proportion x = 14 2/25 / 88/100
= 352 / 25 * 100/88
= 35200 / 25 * 88
= 16 lb (answer).
Answer: 3 hours
Step-by-step explanation:
From the question, we are informed that WHUR Radio uses 1/5 of its of its 10 hours of daytime broadcast for commercial and 1/2 for music.
Hours used for commercial:
= 1/5 × 10
= 2 hours
Hours used for music:
= 1/2 × 10
= 5 hours
Hours left for news will be:
= 10 hours - 2 hours - 5 hours
= 3 hours
