Solve using a proportion.

Advocard [28]

Answer:

t = 24 yards

Step-by-step explanation:

Since the trapezoids are similar then the ratios of corresponding sides are equal, that is

$\frac{t}{c}$ = $\frac{u}{d}$

Substitute in given values

$\frac{t}{0.4}$ = $\frac{15}{0.25}$ ( cross- multiply )

0.25t = 6 ( divide both sides by 0.25 )

t = 24

7. What is the slope of the line that passes through the pair of points (3, 8) and (9, 5) ? (1 point)

agasfer [191]

7. D
8. D
9. D
10.C

for 7 & 8 you use the equation
$\frac{y2 - y1}{x2 - x1}$
your points are (3,8) & (9,5)

so you plug the numbers in
y2= 5
y1=8

x2=9
x1=3
you subtract them get a fraction and that is your slope

9 & 10
use the equation
$y - y1 = m(x - x1)$
plug you numbers in for y1 and x2 m is your slope plug it in and that is your equation
