Mr. Greg had $300 to
purchase equipment
for summer camp. He
bought 6 basketballs
and 6 soccer balls.
Each basketball cost
$16.98, and each
soccer ball cost
$13.79.

The increase in square feet when the garden is enlarged is 400 square feet.

The first step is to determine the perimeter of the fence:

Perimeter = 2( length + width)

2 (60 + 20)

= 160 feet

When the shape of the garden is changed to a square, the perimeter of the square and the rectangle has to be the same.

Length of side of the square = 160 / 4 = 40 feet

Area of the square = 40 x 40 = 1600 square feet

Area of the garden = 60 x 20 - 1200 square feet

Difference = 1600 - 1200 = 400 square feet

Answer:

238

Step-by-step explanation:

First, you must find the ratio between the one measurement of the larger octagon and the smaller octagon. Just divide 28 by 4 to get 7. This is what you have to multiply the perimeter by to get the larger octagon's perimeter.  34 times 7 equals 238. There are multiple ways to do this problem but this way is the simplest.

Answer:

Mean = 29300

median = 23500

Modal = 23000

Step-by-step explanation:

Mean = Add them all and divide by 10

median = average of (rank of 5th and 6th)

= (23000 + 24000) /2

= 23500

Answer:

20.75

Step-by-step explanation:

5.2 lower bound = 5.15

6.3 lower bound = 6.25

9.4 lower bound = 9.35

5.15 + 6.25 + 9.35 = 20.75

Answer:

we know that sum of two complementary angles always equals to 90°

now ∠ABC and ∠CBD are complementary which means ∠ABC + ∠CBD = 90

∠ABC = 35° given

so ∠CBD = 90° - ∠ABC = 90° - 35° = 55°

therefore hence proved ∠CBD = 55°

Answer:

x = [tex]\frac{15}{11}[/tex]

Step-by-step explanation:

[tex]\frac{3}{5}[/tex] x - [tex]\frac{1}{3}[/tex] x = x - 1

multiply through by 15 ( the LCM of 5 and 3 ) to clear the fractions

9x - 5x = 15x - 15

4x = 15x - 15 ( subtract 15x from both sides )

- 11x = - 15 ( divide both sides by - 11 )

x = [tex]\frac{-15}{-11}[/tex] = [tex]\frac{15}{11}[/tex]

Answer:

136°

Step-by-step explanation:

The whole of the cake angle = 360°

Half of it = 180°

Therefore; if 44° angle is eaten out of the half i.e 180°

Then what's left = 180° - 44° = 136°

x = 16

Step-by-step explanation:

2(x - 1) - 6 = 24 ( add 6 to both sides )

x - 1 = 15 ( add 1 to both sides )

x = 16

Answer:

C). 38

Step-by-step explanation:

The range is the measurement of the difference between values in a data set. To find the range, subtract the lowest value from the greatest value.

2, 5, 19, 7, -5, 33, 26, 15, 12

-5, 2, 5, 7, 12, 15, 19, 26, 33

Lowest value,

⇒ -5

Greatest value,

⇒ 33

33 - (-5)

⇒ 38

Hence, the range/answer is 38. ⇒ option c.

10 is the mean of the number that is missing.

A property of an assortment of data that represents an average is called the mean. Depending on the nature of the information as well as the kind of average you require, one can compute the mean theoretically employing any of the several ways. Scheming the data distribution constantly allows one to visually determine the mean as well.

Let the missing number be x.

The sum of all the numbers will be

= 11 + 20 + 3 + 1 + x

= 35 + x

The total number is 5.

The mean is given to be 9.

The mean will be

9 = (35 + x) / 5

9 * 5 = 35 + x

45 = 35 + x

10 = x

Answer: 34

Step-by-step explanation:

The focal length of the lens is 40cm.

The distance between the center of a lens or curved mirror and its focus.

A plane convex lens is made of glass ( n = 1. 5) with one flat surface and the other having a radius of 20 cm.

The focal length of the lens is given by the following formula;

[tex]\rm \dfrac{1}{f}=(n-1) \left ( \dfrac{1}{r_1}-\dfrac{1}{r_2} \right)\\\\Where; \ r_1 =\infty , \ r_2=20, \ and \ n = 1.5[/tex]

Substitute all the values in the formula;

[tex]\rm \dfrac{1}{f}=(n-1) \left ( \dfrac{1}{r_1}-\dfrac{1}{r_2} \right)\\\\\rm \dfrac{1}{f}=(1.5-1) \left ( \dfrac{1}{\infty}-\dfrac{1}{20} \right)\\\\ \rm \dfrac{1}{f}=(0.5) \left ( 0-\dfrac{1}{20} \right)\\\\ \dfrac{1}{f} = \dfrac{-0.5}{20}\\\\\dfrac{1}{f}=-0.025\\\\f = \dfrac{-1}{0.025}\\\\f=-40[/tex]

Hence, the focal length of the lens is 40cm.

A line passes through the two points (-4,6) and (2,-5). 11x +6y - 80 = 0 is the given line equation.

Its slope would be:

[tex]m = \dfrac{y-q}{x-p}[/tex]

The slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

The slope m of the line is given as

[tex]m = \dfrac{y-q}{x-p}\\\\ m = \dfrac{-5-6}{2+4}\\\\ m = \dfrac{-11}{6}[/tex]

The equation of a line is  

[tex]( y -y_0) = m (x - x_0)\\\\( y -6) = \dfrac{-11}{6} (x+4)\\\\6( y -6) = (-11) (x+4)\\\\6y -36 = (-11x +44)\\\\11x +6y - 80 = 0[/tex]
