WILL GIVE BRAINLIEST What is the perimeter of the track, in meters? Use π = 3.14 and round to the nearest hundredth of a meter.

Ivenika [448]

Answer:

Perimeter = 317 m

Step-by-step explanation:

Given track is a composite figure having two semicircles and one rectangle.

Perimeter of the given track = Circumference of two semicircles + 2(length of the rectangle)

Circumference of one semicircle = πr [where 'r' = radius of the semicircle]

= 25π

= 25 × 3.14

= 78.5 m

Length of the rectangle = 80 m

Perimeter of the track = 2(78.5) + 2(80)

= 157 + 160

= 317 m

Therefore, perimeter of the track = 317 m

In a right triangle, the measures of the two smaller angles are (3x+6) and (2x-1). Find the measure of the smallest angle in the

Tema [17]

17
as in right angle one has to be 90 degree others sum should be equal to 90
so if 3x+6 and 2x-1 are smaller angle their sum should add up to 90
3x+6+2x-1=90
x=17

answer is 2x-1 is smallest=33°

(2,-4) reflected over the line y=-x

MatroZZZ [7]

Answer:

(2,4)

Step-by-step explanation:

that would be the answer because when you reflect it over the Y axis you are making the y turn into a + or - depending on what it already is if y=-4 when you reflect it over the y it would be y=4

I bought a box from the post office that has a volume of 24 cubic centimeters.

babunello [35]

The complete question in the attached figure

we know that
[volume of the box]=L*W*H
volume=24 cm³

case A) 10 cm long 4 cm wide and 10 cm hight
volume=10*4*10-----> volume=400 cm³
400 cm³ is not 24 cm³

case B) 2 cm long 2 cm wide and 6 cm high
volume=2*2*6-----> volume=24 cm³
24 cm³ is equal to 24 cm³----> could be the dimensions of the box

case C) 8 cm long 3 cm wide and 1 cm high
volume=8*3*1-----> volume=24 cm³
24 cm³ is equal to 24 cm³------> could be the dimensions of the box

the answer is
case B) 2 cm long 2 cm wide and 6 cm high
case C) 8 cm long 3 cm wide and 1 cm high

Answer:

The correct answer is 17.96875 or approximately 18 inches.

Step-by-step explanation:

Since the ratio of the model truck to the real truck is 5:64, and the length of the truck is 230 inches, that means the length of the model truck would be $\frac{5}{64} * 230$ = $\frac{575}{32}$ = 17.96875 ≈ 18 inches.
