Set up the equation 88+7.25h=169. Now that we have the equation and the only variable to solve is h, we will begin the algebra.
1. Using the Subtraction Property of Equality, subtract 88 from both sides to get the equation 7.25h = 81
2. Now use the Division Property of Equality to divide both sides of the equation by 7.25. You should then get h = 11.1724...
Now assuming he is getting paid by the hour, the number of hours he needs to work to get the skateboard is 12.
Answer:
96 m²
Step-by-step explanation:
The figure is a trapezoid with bases of length 10 m and 22 m, and height 6 m. Putting these numbers into the formula for area of a trapezoid gives ...
A = (1/2)(b1 +b2)h
= (1/2)(10 m +22 m)(6 m) = 96 m²
The area of the figure is 96 m².
By the angle difference formula for sines, we have:
By the angle sum formula for tangents, we have:
.
Rationalizing the denominator gives
as the final answer.
Answer:
The two numbers are 35 and 36.
Step-by-step explanation:
While you could do this question just by 'guess and check', the best way to do it is to divide 71 by 2, which gives 35.5. So out two numbers should be approximately equal to 35.5. So we just take the two closest: 35, and 36, which are consecutive (consecutive means 'one after the other'), and we see add to 71.
So we see that 35 and 36 is the answer.
322/15 = 21.46.....Quincy should buy 22 rolls
