Hello! answer: 7

Step-by-step explanation:

24 × 24 = 576

7 × 7 = 49

576 + 49 = 625

√625 = 25

therefore the missing leg is 7

Answer:

Solution,

Answer:

x = number of children tickets sold = 500

y = number of adult tickets sold = 100

Step-by-step explanation:

Let

x = number of children tickets sold

y = number of adult tickets sold

x + y = 600 (1)

8x + 15y = 5,500 (2)

From (2)

x = 600 - y

Substitute x = 600 - y into (2)

8x + 15y = 5,500 (2)

8(600 - y) + 15y = 5,500

4,800 - 8y + 15y = 5,500

- 8y + 15y = 5,500 - 4,800

7y = 700

y = 700/7

y = 100

Substitute y = 100 into (1)

x + y = 600 (1)

x + 100 = 600

x = 600 - 100

x = 500

x = number of children tickets sold = 500

y = number of adult tickets sold = 100

Answer:

100 cars

Step-by-step explanation:

Alex: Pete

7:        3

Multiply by x to get the number of cars

Alex  has 7x cars

Pete has 3x cars

Now Alex gives pete 20

Alex has 7x-20

Pete has 3x+20

They have the same number of cars so set the expressions equal

7x-20 = 3x+20

Subtract 3x from each side

7x-20-3x = 3x+20-3x

4x-20 = 20

Add 20 to each side

4x-20+20 = 20+20

4x= 40

Divide by 4

4x/4 = 40/4

x = 10

Alex had 7x = 7*10 = 70 to start

Pete had 3x = 3*10 = 30 to start

Together 70+30 = 100 cars

Answer:

100 cars

Step-by-step explanation:

Alex: Pete

7:        3

Multiply by x to get the number of cars

Alex  has 7x cars

Pete has 3x cars

Now Alex gives pete 20

Alex has 7x-20

Pete has 3x+20

They have the same number of cars so set the expressions equal

7x-20 = 3x+20

Subtract 3x from each side

7x-20-3x = 3x+20-3x

4x-20 = 20

Add 20 to each side

4x-20+20 = 20+20

4x= 40

Divide by 4

4x/4 = 40/4

x = 10

Alex had 7x = 7*10 = 70 to start

Pete had 3x = 3*10 = 30 to start

Together 70+30 = 100 cars

Given:

The figure of a wallpaper border.

To find:

The total required border.

Solution:

The given figure has 8 vertices and 8 edges (sides).

From the given figure it is clear that the length ( in feet) of 8 edges of the figure are 12, 2, 2, 2, 2, 3, 12, 7.

We need to find the total required border. So, we have to find the perimeter of the figure.

Add the lengths of all edges to get the perimeter of the given figure.

[tex]Perimeter=12+2+2+2+2+3+12+7[/tex]

[tex]Perimeter=42[/tex]

So, Chloe should buy 42 feet of border.

Therefore, the correct option is B.

Answer:

B

Step-by-step explanation:

It is necessary and the strategic way to collect the waste materials and separate them by material type before recycling. Hence, this is voluntary response bias. The survey overestimates community support for change to the recycling program.

Recycling is the process regenerating new products from the decomposed materials such as broken plastics, fuel from biowastes, glasses from broken glass parts etc.

Recycling technology is a nature genuine strategy and it helps to reduce the accumulation of wastes on earth surface. Not all people are aware of the significance of this method.

Therefore, the bias possible to be occur for the question is from voluntary response and the survey underestimates community support for change to the recycling program.

Answer:

The measure of angle A is 48.4 degrees

Step-by-step explanation:

To find the measure of angle A, we are going to use the cosine rule

We have this as;

a^2 = b^2 + c^2 - 2bc Cos A

a^2 = 11^2 + 13^2 -2(11)(13) cos A

100 = 121 + 169- 286cos A

286 cos A = 290-100

286 cos A = 190

cos A = 190/286

cos A = 0.6643

A = arc cos 0.6643

A = 48.4 degrees

Answer:

a. x is 55

b. 20 white marbles

Step-by-step explanation:

Question: A box contains 60 identical marbles where 'x' of them are red while the rest are white; (given that in the original question, the box only contains red and yellow marbles, the yellow can be replaced by white to explain the question idea)

a. The number of identical marbles in the box, n = 60

The number of red marbles = x

The number of white marbles = The rest of the marbles which are not red

The probability that a marble drawn is white, P(y) = 1/12

Let 'y' represent the number of white marbles

From probability theory, we have;

The number of white marbles, y = n × P(y) = 60 × 1/12 = 5

The number of red marbles, x = n - y = 60 - 5 = 55

x = 55

b. The number of white marbles that must be added to make the probability of choosing a white marble = 5/16 is given as follows;

Let Δy represent the number of white marbles added, therefore;

P(y) = (y + Δy)/(y + Δy + x)

∴ P(y) = (5 + Δy)/(5 + Δy + 55) = 5/16

5 × (60 + Δy) = 16 × (5 + Δy)

300 + 5·Δy = 80 + 16·Δy

16·Δy - 5·Δy = 300 - 80

11·Δy = 220

Δy = 220/11 = 20

The number of white marbles that must be added, Δy = 20 white marbles

The slope is found using two points such as (2014, 450) and (2010, 250)

m = (450 - 250)/(2014 - 2010) = 200/4 = 50
