Simpilfy:

[tex]x2 = 49[/tex]

Jody has a plastic container in the shape of a rectangular prism. The container is 8 1/2 inches long, 4 inches wide, and 3 1/2 inches high. What is the volume of this plastic container?

Answers

Answer:

=119 in ^3

Step-by-step explanation:

The volume of a rectangle prism is given by

V = l*w*h

Changing to decimal form

  = 8 .5 * 4 * 3.5

  =119 in ^3

Answer: 119^3

Step-by-step explanation:

To find out the volume of a rectangular prism you have to multiply length x width x height.

8.5 x 4 = 34

34 x 3.5 = 119^3

A basketball team wants to paint half of a free-throw circle grey. If the radius of the free-throw circle is 5.4 feet, what is the area that will be painted grey? Use 3.14 for , and round to the nearest square foot.

Answers

Answer:

The area which would be painted grey will be "47.7812 ft²".

Step-by-step explanation:

The given values are:

Radius of circle, r = 5.4 feet

Value of pi, π = 3.14

As we know,

Area of Semicircle = [tex]\frac{\pi r^2}{2}[/tex]

On putting the values in the above formula, we get

                               = [tex]\frac{3.14\times (5.4)^{2}}{2}[/tex]

                               = [tex]\frac{3.14\times 29.26}{2}[/tex]

                               = [tex]\frac{91.5624}{2}[/tex]

                               = [tex]45.7812 \ ft^2[/tex]

The diagram shows a right-angled triangle and a parallelogram.

30 cm base of parallelogram
7cm base of triangle

The area of the parallelogram is 5 times the area of the triangle.
The perpendicular height of the parallelogram is hcm.
(b) Find the value of h.

Answers

Answer:

see explanation

Step-by-step explanation:

i know this is very late but ..

area of triangle= b*h/2

24*7/2=84

and it said the parallelogram is 5 times the area so we do

84*5=420 which is the total area of the parallelogram

now to find h we need to do

420/30=14

h=14 because 30*14=420

The required value of h is 14 cm for the given parallelogram.

What is Parallelogram?

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

The area of the triangle is (247)/2 = 84 square cm.

Since the area of the parallelogram is 5 times the area of the triangle, the area of the parallelogram is 845 = 420 square cm.

The area of the parallelogram is equal to the base (30 cm) multiplied by the height (h cm), so we can set up the equation:

30h = 420

To find the value of h, we can divide both sides of the equation by 30:

h = 420/30

h = 14 cm

Thus, the required value of h is 14 cm.

Determine the nth term formula for each of the following sequences and find the limit if it exists.

Answers

Answer:

aₙ = (-3) (-1)ⁿ⁻¹

limit does not exist

Step-by-step explanation:

-3, 3, -3, 3, ...

This is an alternating geometric series where the first term is -3 and the common ratio is -1.  The nth term is therefore:

aₙ = (-3) (-1)ⁿ⁻¹

Since the sequence alternates between -3 and 3, the limit as n approaches infinity of aₙ does not exist.

Answers

64.5 m

Step-by-step explanation:

1)  Find the width:  A = L*W, and so W = A / L  =  (256.5 m²) / (18 m) = 14.25 m.

2)  Find the perimeter, using the formula P = 2L + 2W:

Here P = 2(14.25 m) + 2( 18 m) = 64.5 m

Which statement about liters and milliliters is true?

Answers

Answer:

Lesson Summary

A milliliter is a metric unit used to measure capacity that's equal to one-thousandth of a liter. Capacity is the amount of liquid a container can hold. One liter contains 1,000 milliliters, so to convert liters to milliliters you multiply the number of liters times 1,000.

Look at the equivalent metric units of capacity. When converting from a larger unit to a smaller unit, multiply by 1,000. When converting from a smaller unit to a larger unit, divide by 1,000. Liters are larger than milliliters, so multiply by 1,000.

Answer:

Its B. y-5x+5

Step-by-step explanation:

Use the slope formula

The equation of the linear model is y = 5x + 5. The correct answer is option B.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We can find the equation of the linear model passing through two points using the slope-intercept form of a line:

y = mx + b

where m is the slope of the line and b is the y-intercept.

First, we need to find the slope of the line:

m = (y₂ - y₁) / (x₂ - x₁)

Let (0, 5) be the first point, and (3, 20) be the second point:

m = (20 - 5) / (3 - 0) = 15 / 3 = 5

Now that we know the slope, we can plug in one of the points and solve for the y-intercept:

y = mx + b

5 = 5(0) + b

b = 5

Hence, the equation of the linear model is:

y = 5x + 5

Answers

Answer: 21

Step-by-step explanation:

From the question, a spinner with seven equal sized sections was used in playing a game. The spinner was used 250 times in the first game and the arrow landed on section 7 a total of 35 times. This can be expressed as:

= 35/250

= 0.14

The same spinner was also used 150 times in the second game. The number of times the spinner will most likely land on section 7 in the second game will be:

= 0.14 × 150

= 21

The spinner most likely land on section 7 in the second game for 21 times.
