It’s 8sqrt3 . You can use the Pythagorean theorem- A squared plus B squared equals C squared. You can plug them and getting eight squared plus B squared equals 16 squared. Eight squared is 64 and 16 squared is 256. Subtract 64 from 256 and that leaves you with eight square root of three

*ANSWER ASAP* Earth has a diameter of approximately 7926 miles. Determine the volume of Earth.

Answers

Answer:

Rounding to the nearest whole number, 49 moons can fit in the earth.

Rounding to the tenth place, 50 moons can fit in the earth.

Step-by-step explanation:

To find how approximately how many moons could fit inside the earth, you would need yo find the volumes the earth and the moon.

V = 4/3 π r^3

Earth:

d = 2r

d = 7926 miles

7926 = 2r

3963 miles = r

V = 4/3 π (3963)^3

V = 4/3 π (62240377347)

V = 82987169796π cubic miles

Moon:

d = 2r

d = 2159 miles

2159 = 2r

1079.5 miles = r

V = 4/3 π (1079.5)^3

V = 4/3 π (1257963209.88)

V = 1677284279.83π cubic miles

Now you divide the volume of earth by the volume of moon to find how many moons can fit in earth

82987169796π ÷ 1677284279.83π =

approx 49

Andrea and Damian are collecting clothing items to donate. When they begin tracking their progress, Damian already has 5 items collected. Damian's goal is to collect 3 items per day, and Andrea's goal is to collect 4 items per day.

Answers

Answer:

5 days

Step-by-step explanation:

Given

Damian

[tex]Base\ Items = 5[/tex]

[tex]Rate = 3[/tex] daily

Andrea

[tex]Rate =4[/tex] daily

Required [Missing from the question]

How long will they get the same number of items

Represent the number of items with x and the days with y.

So:

For Damian

[tex]y = Base\ Items + Rate * x[/tex]

[tex]y = 5 + 3 * x[/tex]

[tex]y = 5 + 3 x[/tex]

For Andrea

[tex]y = Rate * x[/tex]

[tex]y = 4* x[/tex]

[tex]y = 4x[/tex]

Equate both expressions.

[tex]4x = 5 + 3x[/tex]

Collect like terms

[tex]4x - 3x = 5[/tex]

[tex]x = 5[/tex]

Hence, they will have equal amount of items after 5 days

Let r be the number of roses she uses and let c be the number of carnations she uses. Write a system of inequality’s that represents this scenario.

Answers

Answer:

r + c ≤12

r > 3

c > 2

Step-by-step explanation:

Jennifer is putting together a selection of flowers that has at most 12 flowers in it.

r = number of roses she uses

c = the number of carnations

At also means Less than or equal to.

It is represented by ≤

She is choosing either roses or carnations. She wants to pick at least three roses

r > 3

and at least two carnations.

= c > 2

Therefore, the system of inequality that represents this scenario is written as:

r + c ≤ 12

r > 3

c > 2

The upper-left coordinates on a rectangle are (-1, 7), and the upper-right coordinates are (4,7). The rectangle has an area of 20 square units. Draw the rectangle on the coordinate plane below.

Answers

Answer:

The answer is below

Step-by-step explanation:

The distance between the upper left coordinate and the upper right coordinate is the length of the rectangle. Hence:

[tex]length=\sqrt{(4-(-1))^2+(7-7)^2} =5\ units\\[/tex]

Area = length * breadth

20 = 5 * breadth

breadth = 4 units

The bottom left coordinate would have the same x coordinate as the upper left coordinate. Hence, bottom left coordinate = (-1, y₁)

The distance between the upper left coordinate and the bottom left coordinate is the breadth of the rectangle. Hence:

[tex]breadth=\sqrt{(-1-(-1))^2+(y_1-7)^2} =4\ units\\\\ y_1-7=\pm 4\\\\y_1=4+7=11\ \ or\ y_1=-4+7=3[/tex]

Since it is at the bottom, hence y₁ = 3. Hence bottom left coordinate = (-1, 3)

Bottom right coordinate has same y coordinate as bottom left coordinate and same x coordinate as upper right. Hence bottom right coordinate = (4, 3)
