First, you add the values you're looking for (green and black, 4+3=7)you make a fraction over the total number of marbles(20). then you multiply the fraction by 5 because you drew 100 times(20×5=100).
Answer:
Step-by-step explanation:
Given that:
4x + 5x = $440
9x = $440
x = $49 (Approx.)
So, she received :
from the stock = 4 x 49 = $196
from the bond = 5 x 49 = $245
SO, now, how much did she invest ?
I cant see the triangles but look for 1 with a 90 degree angle. if it has 1 90 degree angle then that is you answer
Given adjacent = 14.7
Given degree = 41
Find hypothenuse
Sohcahtoa (use cah to find hypothenuse)
Cosine = adjacent/hypothenuse
Cos(41) = 14.7/h
0.7547095802 = 14.7/h
14.7/0.7547095802 = 19.477691
Round to nearest tenth:
Solution: 19.5
Answer:
Step-by-step explanation:
Translating to English:
A cylinder has a volume that is 25% greater than a sphere with a surface area of . What is the cylinder's volume?
<u>Solution:</u>
This isn't a hard question. You do not need to get inside the nitty gritty of the formula for volumes and surface areas. The SA of sphere is given and we are told the VOLUME of CYLINDER is 25% GREATER THAN THIS!
So, we just need to figure out what is 25% greater than
Lets keep the as constant and find 25% greater than 576 and we tag along the .
We need to find 25% of 576 and add it to 576 to get our answer.
25% = 25/100 = 0.25
So,
0.25*576 = 144
So,
144 + 576 = 720
The answer would be
The 2nd answer choice (with a typo here), is correct.
