Nikitich [7]

Answer:

6 students at the preschool of four years old attended the full day program.

Step-by-step explanation:

Given:

Number of four years old students = 16

fraction of four years old students attended full day program = \frac{3}{8}

We need to find the number of four years old students attended the full day program.

Solution:

Now we can say that;

number of four years old students attended the full day program is equal to fraction of four years old students attended full day program multiplied by Number of four years old students.

framing in equation form we get;

number of four years old students attended the full day program = \frac38\times 16 =6

Hence 6 students at the preschool of four years old attended the full day program.

Question 4) Identify the surface area of the composite figure.
netineya [11]

The surface area of the composite figure is given by 730 sq.in

<h3>What are Composites ?</h3>

Composites are solid figures made up of basic shapes like rectangle , square and even of three dimensional figures like cube , cuboid etc.

It is given in the question to determine the area of the composite figure

Area of Cube is

Area = 6 * side²

Area = 6 * 4² = 96 sq.in

The surface area of the cuboid is equal to

Sum of surface area of all the sides

As the opposite sides are same

7x10x2 + 15x10x2 + 7x15x2

650 sq.in

As the surface area of the base of the cube is counted twice

Therefore it will subtracted from the total

96 + 650 - 4*4

=730 sq.in

Therefore the surface area of the composite figure is given by 730 sq.in

Which car can travel at the slowest rate? Plz help fast
grigory [225]

Answer:

D


Step-by-step explanation:

Let's find unit rate of each (number of miles traveled in 1 hour). For that we will divide the distance by time to get the unit rate.

Note: rate=\frac{Distance}{Time}


(A)

rate = \frac{300}{4}=75 mph (miles per hour)

(B)

rate = \frac{450}{6}=75 mph

(C)

rate = \frac{750}{10}=75 mph

(D)

rate = \frac{800}{12}=66\frac{2}{3} mph


<u>As we can see, the first 3 rates are same, 75 mph, and the last one is 66\frac{2}{3} mph. So clearly, the last rate is the slowest.</u>

D is the right answer.
