Answer:
acute: 7, 9
right: 8, 10
obtuse: 5, 6
Step-by-step explanation:
When you have a number of identical calculations to do, it is convenient to do them in a spreadsheet. You only need to enter the formula once and copy it as many times as needed.
The attachment shows the "sum of squares" calculation and comparison to the square of the longest side. When the sum is too small, the longest side is longer than needed for a right angle, so the triangle is obtuse. When the sum is too great, the longest side is too short for a right angle, so the triangle is acute.
We have skipped the tedious arithmetic and shown the results in the attached table.

Answer:
$9.6
Step-by-step explanation:
The computation of the price of the mixture is shown below:
The price of candy is
= 3 lbs × $1.7 per pound
= $5.1
And for other the price is
= 5 × 0.90
= $4.5
So, the total price of the mixture be
= $5.1 + $4.5
= $9.6
In this case, it's clear that 5 is half of ten, therefore, you have to divide the first equation in half, giving you 5x42= 210. If it was something such as 20x24, you just work the answer from the multiple of ten.

9 miles is = 60% of the distance she ran all the week.
9 = 60% of x.
9 = 0.60 * x.
0.6 x = 9 . Divide both sides by 0.6.
x = 9 / 0.6
x = 15.
Total distance = 15 miles.
