Probability1 *Probability2
0.35 = 0.48 * P2
0.35/0.48 = P2
P2 = 0.7291666...,

The answer is true. An exponent is how many times you multiply (10) by (10).
10^1=10
10^2=10*10=100
and so on
Answer:
The cost of one cup of hot chocolate is $4.50
Step-by-step explanation:
Let
x ----> the cost of one cup of hot chocolate
y ----> the cost of one cup of hot tea
we know that
3x+4y=25.50 ------> equation A
y=(2/3)x -----> equation B
Solve the system of equations by substitution
substitute equation B in equation A and solve for x
3x+4(2/3)x=25.50
3x+(8/3)x=25.50
(17/3)x=25.50
x=25.50*3/17
x=$4.50
therefore
The cost of one cup of hot chocolate is $4.50
Answer:
161 is your answer.
Step-by-step explanation:
Easy! If Kiersten has 23 balloons and Catherine has 8 times more than Kiersten, all we need to do is multiply. 23x8=184. Now to figure out how many more red balloons Catherine has compared to Kiersten we need to subtract Kiersten's amount from Catherine's amount. 184-23=161. So Catherine has 161 more red balloons than Kiersten.
