Answer:

New height = 11/2 ft

New height = 5 + 1/2(N)

Step-by-step explanation:

Given:

Initial height = 5 ft

Grown height = 1/2 ft

Find:

New height

Computation:

New height = Initial height + Grown height

New height = 5 + 1/2

New height = 11/2 ft

Equation;

New height = 5 + 1/2(Number of year)

New height = 5 + 1/2(N)

B. 25

Add 25 to the total of 220 then divide by the 7 days to get a mean of 35 cars

Answer:

Step-by-step explanation:

Well, the formula to find slope is y2-y1 / x2-x1

Here's an example:

(2,12) (4,24)

12-24 / 2-4 =

-12/-2 or 6

You would use:

(y=mx+b) to find an entire equation, including the y intercept

Let me know if this helps, and if it doesn't, I hope I'll be able to explain it better.

Answer:

Number of ice cream cones = 65

Number of sundaes = 49

Step-by-step explanation:

Let

x = number of ice cream cones

y = number of sundaes

x + y = 114 (1)

2x + 3.5y = 301.50 (2)

From (1)

x = 114 - y

Substitute into (2)

2x + 3.5y = 301.50 (2)

2(114 - y) + 3.5y = 301.50

228 - 2y + 3.5y = 301.50

- 2y + 3.5y = 301.50 - 228

1.5y = 73.50

y = 73.50/1.5

y = 49

Substitute y = 49 into (1)

x + y = 114 (1)

x + 49 = 114

x = 114 - 49

x = 65

Number of ice cream cones = 65

Number of sundaes = 49

Answer:

Step-by-step explanation:

Answer:

8 sq units

Step-by-step explanation:

area of square in middle is 2 x 2 = 4 sq units

area of one triangle is 1/2(2)(2) = 2 sq units

however, there are two triangles, so you have to double 2 to get 4

4 + 4 = 8

Answer:

8cm^2

Step-by-step explanation:

Method 1: It's a trapezium, so take the top length, (6cm), add it to the bottom length (2cm) = 8cm which is then divided by 2 (4cm) then multiplied by the height (2cm) giving an area of 8cm squared.

Method 2: area of the square = 2 x 2 = 4cm^2

Triangle 1: 2 x 2 = 4, divided by 2 = 2cm^2

Triangle 2: same as triangle 1.

Total: 4 + 2 + 2 = 8cm^2

Answer:

9+10= 19

Answer:

{-2,-1,0,1,2}

Step-by-step explanation:

When we are talking of the range, we are referring to the possible y-values the relation can take

Hence, a set of y-values will represent the range of the relation

we have this as:

{2, 1 , 0, -1 , -2}

Arranging in order, we have ;

{-2,-1,0,1,2}

Answer:

74 yards wide and 116 yards long

Answer:

Step-by-step explanation:

Remark

Later on, in a not so distant future, you will learn that the maximum area of a rectangle can be obtained when you are dealing with a square.

So to get the maximum area, change the rectangle into a square. Leave the perimeter the same.

Formulas

Perimeter = 2L + 2W

Perimeter = 4*s for a square

Area = s^2

Givens

L = 115

P = 75

Solution

P = 2 * 115  + 2 * 75

P = 230 + 150

P = 380

Perimeter of a square

P = 4*s                Substitute

4s = 380            Divide by 4

s = 95

Check

Area of  original Rectangle = 115 * 75 = 8625

Area of the derived square = 95^2 = 9025

Answer:

[tex]c = kw[/tex]

Step-by-step explanation:

Given

c varies directly as w

Required

Write the equation

c varies directly as w.

Mathematically, this is represented as:

[tex]c\ \alpha\ w[/tex]

Convert to equation.

[tex]c = kw[/tex]

Where k is the constant of variation

Answer:

Tax amount = $36.25

Step-by-step explanation:

The tax rate is 7.25%.

We need to find the tax be on a $500 TV.

It can be calculated as follows :

[tex]C=500\times 7.25\%\\\\=500\times \dfrac{7.25}{100}\\\\=\$36.25[/tex]

So, the required tax on $500 TV is $36.25.
