Answer:

(88°/360°) * total number of students= 110

88x=39600

x=450 students

x is the total number of students

(140/360)*450=175 students going by bus

if u like my answer mark as brainliest

Find the surface area of the rectangular prism
frutty [35]

Answer:82

Step-by-step explanation:

surface area=pxh + 2xb

p=perimeter of base

h=height

b=area of base

Perimeter of base=7+7+2+2=18

height=3

base area=7x2=14

surface area=18x3+2x14

Surface area=82

Will mark brainliest, please answer correctly!!!
Mariana [72]

Answer:

The length of BC is 17 units

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

In this problem we have an isosceles triangle

Because

m∠ACB=m∠ABC ----> given problem

so

AC=AB

substitute the given values

x+9=2x-8

solve for x

2x-x=9+8

x=17

therefore

The length of BC is 17 units

The modern day equation that models this problem is x + 1/4x = 15.
GREYUIT [131]
The answer I think is 12. 

<span>x + 1/4x = 15= 12

I hope this helps.

If I am right, which I am pretty sure I am, can you make my answer the brainliest please?</span>

I need help with this and I don’t understand it
DochEvi [55]

Lets break it down:

The bottom right picture shows an approximation of what 1 wingspan length is, and the goal is to <u>estimate </u>lengths.

A. 1 wing is approx. 7 meters. To find the wingspan of the plane just do 7 meters multiplied by 2 = 14 meters (approx wingspan). Now we convert (remember, to the nearest foot!)

14 meters = 45.93 ft

Round it to the nearest foot = 46 ft is your approx. wingspan.

B. The height. This is one is a little tricky! Lets try to use what we know:

1 wing is approx. 7 meters. Since these are approximations, lets say half of one wing is <u>roughly</u> the size of the height of the plane. Since these are approximations I'd say 4 meters.

4 meters = 13 ft (rounded).

<em>I checked online for the specs of the Lysander and the exact height is 14 ft 6 in and wingspan is 50 ft. </em>This means our approximations were correct!

C. The length would be 10 ft + 7 meters

10 ft = 3 meters (rounded)

3 meters + 7 meters = 10 meters

<em>(converting to meters then to ft at the end because it's less messy)</em>

10 meters = 33 ft (rouned)

length of the Lysander is approx. 33 ft!

(the real length is 30 ft 6 in)

This means our approximations were correct once more.

Hopefully this helped you and made your night/day easier.
