Answer:

36 ft

Step-by-step explanation:

So the proportion of the big triangle is 48:4 or 12:1. So if the small triangle’s height is 3 feet, then 3*12 is 36 feet.

Answer: 36 ft

Step-by-step explanation:

Similar triangles means there is a constant proportion between the left legs, the base legs, and the hypotenuses.

$\frac{LeftLeg(large)}{LeftLeg(small)}= \frac{BaseLeg(large)}{BaseLeg(small)}$

$\frac{x}{3}= \frac{48}{4}$

Cross multiply: x(4) = 3(48)

solve for x: ÷4 ÷4

x = 3(12)

= 36

stich3 [128]

Answer:

$D: y= -5x+12$

Step-by-step explanation:

Since the slope is -5 is either C or D. Let's replace $x= 2$ in either to see what we get.

C: $-5(2)-2 = -12$ Nope.

D: $-5(2) +12 = 2$ Good!

Find x make sure you simplify your answer

lorasvet [3.4K]

Answer:

$h^{2}$ + $6^{2}$ = $8^{2}$

$h^{2}$ + 36 = 64

$h^{2}$ = 64-36

$h^{2}$ = 28

$\sqrt{28}$ = 2 $\sqrt{7}$

h = 5.29

Ni Hua is an adventurous traveler. He skydives twice in every island he visits and skydives thrice in every peninsula he visits.

Gnesinka [82]

Let the number of islands visited be x and that peninsulas be y
thus,
x+y=19
⇒y=19-x.........i
if he skydives twice in islands and thrice in peninsulas, then the total number of skydives will be:
2x+3y=45.....ii

substituting i in ii we get:
2x+3(19-x)=45
2x+57-3x=45
putting like terms together we get:
2x-3x=45-57
-x=-12
therefore
x=12
and
y=19-x=19-12=7
hence the number of islands visited was 12 and that of peninsulas was 7
