Answer:

z = 1

Step-by-step explanation:

90/15 = 6/z

Cross multiply

We have

90 x z = 15 x 6

90z = 90

Divide both sides by 90

90z/90 = 90/90

z = 1

Will the ball clear the crossbar of the goal post, which is 10 feer off the fround.
Allisa [31]

The problem gives you X, so replace X witht he given vaule and solve for y:


y = -0.1x^2 + 4X

X = 40

y = -0.1(40)^2 +4(40)

y = -0.1(1600) + 160

y = -160 + 160

y = 0

The median is 28; 16,24,x,48
Nookie1986 [14]
x = 32 

To find the media, you take the middle number. If there is no discrete middle number, take the sum of the two closest to the middle and divide by 2. 

(24 + x)/2 = 28

Multiply by 2 on both sides to get:

24 + x = 56

Subtract 24 from both sides to isolate the variable:

x = 56 - 24
x = 32

0 =  - 4.9t {}^{2}  + 27t + 2.4
Convert decimals to fractions

0 =  -  \frac{49}{10} t {}^{2}  + 27t +  \frac{12}{5}
Multiply both sides by 10

0 =  - 49t {}^{2}  + 270t + 24
Move expression to the left.

0 + 49t {}^{2}  - 270t - 24 = 0
Remove zero.

49t {}^{2}  - 270t - 24 = 0Solve the quadratic equation.

t =  \frac{ - ( - 270) +  -  \sqrt{( - 270) {}^{2} - 4 \times 49 \times ( - 24) } }{2 \times 49}
Remove parenthesis and calculate.

t =  \frac{270 +  -  \sqrt{72900  + 4704} }{98}
Add the numbers

t =  \frac{270 +  - 77604}{98}
Separate the solutions

t =  \frac{270  +  \sqrt{77604} }{98}  \\ t =  \frac{270 -  \sqrt{77604} }{98}
The final solution are
t1 =  \frac{270 -  \sqrt{77604} }{98} , t2 =  \frac{270 +  \sqrt{77604} }{98}
