Answer:

56

Step-by-step explanation:

Given that:

Number of girls = 3

Number of boys = 4

Each student makes 8 paper airplanes.

To find:

The total number of airplanes = ?

Solution:

There can be two ways to find the total number of airplanes.

Method 1:

Keep on adding the number of airplanes for each student.

There are a total of 3+4 = 7 number of students.

First student makes = 8 airplanes

Second student makes = 8 airplanes

Third student makes = 8 airplanes

Fourth student makes = 8 airplanes

Fifth student makes = 8 airplanes

Sixth student makes = 8 airplanes

Seventh student makes = 8 airplanes

Total number of airplanes = 8 + 8 + 8 + 8 + 8 + 8 + 8 = <em>56</em>

<em></em>

Method 2:

Simply multiply number of airplanes each student makes with the number of students.

i.e. 8 \times 7 = <em>56</em>

The diagram shows a scale drawing of a playground the scale of the drawing is 1:500 work out the perimeter of the real playgroun
liraira [26]

Answer:

Check Explanation

Step-by-step explanation:

The complete question plus diagram is presented in the attached image to this solution.

From the attached image, the dimensions of the playground drawn will be a bit variable now as zooming and some editing might have tampered with the original intended dimensions to be measured.

But still, let us assume that on measuring the rectangular playground shown, we obtain approximately that the length is 4.5 cm and the breadth is 2 cm.

The scale to convert to real life is 1;500 indicating that

1 cm on the drawing = 500 cm lenght units of the real playground.

So,

4.5 cm on the drawing = 4.5 × 500 = 2250 cm of the playground

2 cm on the drawing = 2 × 500 = 1000 cm of the playground.

Hence, the real life dimensions of the playground is 2250 cm by 1000 cm.

In meters, that is 2.25 m by 1 m

The perimeter of a rectangular figure is given as

Perimeter = 2(Length + Breadth)

= 2(2.25 + 1)

= 6.5 m

Hope this Helps!!!

Jamal is running 42 kilometers. The amount of time t it takes Jamal to run varies inversely with the rate, r, at which he runs,
leva [86]

Answer:

t α 1 /r ; t = k/r

Step-by-step explanation:

Given that :

Time taken, t varies inverse as rate, r

MATHEMATICALLY,

t α 1 /r

Hence,

t = k/r ;

Where, k is the proportionality constant

Hence, the situation could be expressed as :

t = k/r OR

t α 1 /r
