Answer:
55
Step-by-step explanation:
In a triangle all the angles = 180 degrees
That means: x + y + 90 = 180
x + y = 180 - 90 = 90
35 + y = 90
y = 90 - 35
y = 55 degrees
Simply find the total medium cofees sold
then divide that by the number of medium cofees that weren't caffeinated
so..
![66 \div 44 = x](https://tex.z-dn.net/?f=66%20%5Cdiv%2044%20%3D%20x)
then
![100 \div x = percentage](https://tex.z-dn.net/?f=100%20%5Cdiv%20x%20%3D%20percentage)
so x will be 1.5 & 100 ÷ 1.5 = 66.666...
rounded is 67%
I'm not quite sure these are right. You might wanna check with a classmate or something first.
Step-by-step explanation:
(6x + 10) + (x + 17) + (4x - 34) = 180
11x - 7 = 180
11x = 173
x = 15.73 (answer had repeating decimal so i rounded up in the hundredths place)
(6x + 10)
6 (15.73) + 10
94.38 + 10
104.38
(x + 17)
(15.73) + 17
32.73
(4x - 34)
4(15.73) - 34
62.92 - 34
28.92
Answer: D) randomized comparative design
Step-by-step explanation:
Randomized comparative design is an experiment which uses comparison of two or more treatments, also known as an experiment designed to show differences between two samples or populations which have being exposed to two different conditions or treatments are compared to each other. In the question above data collected before was compared to data gotten after the dangers of alcohol.
