Answer:

Rajini is correct, A = 1/2 × 9 × 7

Step-by-step explanation:

A = 1/2 × base × height

base = the leg bisected by the height, in this case leg QD = 9cm

height = 7cm in this case

Graph the linear equation by plotting the x and y intercepts <br> x +4y -16 =0

ira [324]

Answer:

x intercept = 16

y intercept = 4

Step-by-step explanation:

For the x intercept...y = 0...where the equation would be...x + 4(0) = 16..hence giving us the x intercept as... x = 16

For the y intercept...x = 0...where if we substitute x = 0 into our equation...the equation would be....0 + 4y = 16..hence giving us..., 4y = 16...divide both sides by 4...y = 4

A car is driving at 100 kilometers per hour. How far does it travel in 2 seconds?

Alisiya [41]

Answer:

$\frac{1}{18}\ km$ or $\frac{500}{9}\ m$

Step-by-step explanation:

Remember that

1 hour=3,600 seconds

by using proportion

$\frac{100}{3,600}\frac{km}{sec} =\frac{x}{2}\frac{km}{sec} \\ \\x=2*100/3,600\\ \\x=\frac{1}{18}\ km$

Convert to meters

$(1,000)*(\frac{1}{18})=\frac{500}{9}\ m$
