Answer:

The answer would be x= 45

There are 3 ways to answer this question.

1st Way (The Fastest)

160 - 115 = 45

2nd Way

160 - 180 = 20

160 + 20 + 20 + 115 = 315

315 - 360 = 45

3rd Way

160 - 180 = 20

20 + 115 = 135

135 - 180 = 45

Hope This Helps

There are 11 people in a group. Four of them are selected to be on a panel. If John is in the group, what is the probability he

Fynjy0 [20]

Answer:

$\frac{7}{11}$

Step-by-step explanation:

Probability is defined as the likelihood of an event occurring.

-The probability of being selected is :

$P_s=\frac{4}{11}$

-The probability of not being selected is :

$P_{ns}=1-P_s\\\\=1-\frac{4}{11}\\\\=\frac{7}{11}$

Hence, the probability of John not being selected is $\frac{7}{11}$

B. Second two rectangles are dilations because

$\dfrac{2}{4}=\dfrac{3}{6}=0.5$

C. Third two rectangles are not dilations because

$\dfrac{3}{4}\neq \dfrac{2}{3}$

D. Fourth two rectangles are dilations because

$\dfrac{3}{4}=\dfrac{1.5}{2}=0.75$

A model rocket is fired from the ground at time t=0, and it’s height is given in cm by the formula h=-490t^2 +1470t where t is m

Natali [406]

Step-by-step explanation:

h = -490t² + 1470t

When h = 980:

980 = -490t² + 1470t

Simplifying:

0 = -490t² + 1470t - 980

0 = t² - 3t + 2

Factoring:

0 = (t - 1) (t - 2)

t = 1, 2

There are two solutions because the rocket first reaches the height of 980 cm as it's going up at 1 second, then it reaches that height again as it's coming down at 2 seconds.
