Find the missing length
gregori [183]

Answer:

? = 55

Step-by-step explanation:

if we put the triangles onto of each other

side CT is on top of TR

126 ÷ 70 = 1.8

70 × 1.8 = 126

BT is on top of TS

so,

99 ÷ ? = 1.8

99 = 1.8 × ?

99 ÷ 1.8 = ?

55 = ?

55 × 1.8 = 99

Hoped i helped :)

A stain glass window is shaped like a semicircle. The bottom edge of the window is 36 inches long. What is the area of the stain
Lubov Fominskaja [6]
I don't really have a calculator on me. But I'll tell you how to go through it.
So the formula for the area of a circle is Pi x radius^2.
So since the diameter is 36, divide that by 2 to get the radius, and you're left with 18. Now do 18 squared and then times that by Pi. Now you've got the area of the whole circle, but since we only have a semicircle, you need to divide your answer by two to get the area of the semi circle

Vaselesa [24]

Answer: a) sample

b) quantitive.

Step-by-step explanation:

Given: A recently published research study looked at 3000 people over a period of 15 years and determined that those people who ate fast food two or more times per week had gained an average of 10 pounds more than the group who ate fast food less than twice a week.

Here, population  = "people who ate fast food two or more times per week"

Since a census is the data of all members in a population whereas a sample is a subset of it.

Then, 3000 people constitute a sample as it is a subset of the population.

Since the researcher's point of interest it to measure average weight gain which is a quantitive measure.

So, the data is quantitative.

Target is having a Back to School sale where all polo shirts are discounted by 20%. Joshua wants to buy five shirts: two cost $1
RUDIKE [14]

Answer:

$39.03

Step-by-step explanation:

Joshua wants to buy five shirts:

  • two cost $10.98 each,
  • one costs $11.50,
  • two others cost $15.99 each.

Total cost of all shirts:

2\cdot\$10.98+\$11.50+2\cdot \$15.99=\$65.44

All polo shirts are discounted by 20%, then the total cost of all shirts is

\$65.44\cdot (1-0.2)=\$52.352

Joshua had a coupon in his pocket that would take an additional 30% of the shirts, then the total price will be

\$52.352\cdot (1-0.3)=\$36.6464

He has to pay sales tax of 6.5%, so the total price will be

\$36.6464\cdot (1+0.065)=\$39.028416\approx \$39.03
