Answer:

Step-by-step explanation:
When finding area of any shape, the given two numbers are different sides must be multiplied.
Area of formula:
A = L * W
Substitute:
A = 15 * 12
Multiply:


180(A) = 15(L) * 12(W)
Answer:
3 because 3 x 2 + 3 x 8 = 30 and 3(2+8)=30
Answer=12.6
QR=9
QP=6
TU=19
TS=?
The triangles are similar, so the following equation can be made
9 6
____=____
19 x
Cross multiply
9x=114
divide both sides by 9
x=12.6 (with the 6 repeating) or 12 2/3
TS=12.6
Answer:
C, The marble is 3 times as likely to be black as it is to be white.
Step-by-step explanation:
The probability of a marble being drawn is:
number of marbles of that color/total number of marbles
Find total number of marbles
5+8+4+15= 35
So the probability of drawing:
white: 5/32
polka dot: 8/32
striped: 4/32
black: 15/32
The probability of drawing white, polka dot, or striped is obviously different, so A is wrong.
The probability of drawing every color but black is 5/32 + 8/32 + 4/32 = 17/32, which is more than the chance of drawing black, so B is wrong.
The probability of drawing black is 15/32, and that is 3 times larger than the probability of drawing white (5/32), so C is correct.
The probablility of drawing a polka dot is 8/32, which is not four times as large as stripe (4/32), so D is wrong.
Step-by-step explanation:
The expression is 6y - 4x
1) 6y - 4x
2) 8y - 4x
3) 4x + 6y
4) 6x - 4y
The correct answer is option 1
