how do i find the missing length of a rectangel

Answer:

After 1.87 seconds the skateboarder is 8 ft from the bottom of the hill.

Step-by-step explanation:

The quadratic function d = –2*x² + 15 models a skateboarder’s distance, in feet, from the bottom of a hill x seconds after the skateboarder starts moving down the hill.

You want to know after how many seconds the skater is 8 feet from the bottom of the hill. That is, with the distance being 8 feet, you want to calculate the time t. Replacing in the expression d by the value of 8 feet:

8=–2*x² + 15

Solving:

8-15 = -2*x²

-7= -2*x²

(-7)÷(-2)= x²

3.5= x²

√3.5=x

1.87= x

After 1.87 seconds the skateboarder is 8 ft from the bottom of the hill.

Step-by-step explanation:

The total value would be 90 , as it is a right triangle . Starting from the aforementioned number and subtracting it by the given values above shall reward you with the correct answer .

90 - ( 6 + 3 ) = 81

81 / 3 = 27

If the radius of the sphere is doubled, the volume would be multiplied by 4. Think of the sphere as a cube instead and if you were to double the sides, the area would be 4 times bigger. Hope this helps! :)

The number of years it will take until the stalactite is 1 meter long is; 70 years

From conversion units, we know that;

1 m = 100 cm

1 cm = 100 m

Current length is given as 72 cm

Thus;

Length after x years = 1 m = 100 cm

Length increase in x years  = 100 -72 = 28 cm

Since 1 cm = 10 mm

Then;

Length increase in x years  in mm = 28 * 10 = 280 mm

Thus;

Length increase in 1 year = 4 mm

Length increase in x years = 4x mm

Then; 4x  = 280

x = 70

Thus, it will take 70 years  until it is 1 meter long.

Answer:

[tex]t = 0.375s[/tex]

Step-by-step explanation:

Given

[tex]h(t) = -16t^2 + 4t + 33[/tex] --- driver 1

[tex]Rate = 2ft/s[/tex] -- driver 2

[tex]height = 33ft[/tex]

Required

The time they passed each other

First, we determine the function of driver 2.

We have that:

[tex]Rate = 2ft/s[/tex] and [tex]height = 33ft[/tex]

So, the function is:

[tex]h_2(t) = Height - Rate * t[/tex]

[tex]h_2(t) = 33 - 2t[/tex]

The time they drive pass each other is calculated as:

[tex]h(t) = h_2(t)[/tex]

[tex]-16t^2 + 4t + 33= 33 - 2t[/tex]

Collect like terms

[tex]-16t^2 + 4t + 2t= 33 - 33[/tex]

[tex]-16t^2 + 6t= 0[/tex]

Divide through by 2t

[tex]-8t + 3= 0[/tex]

Solve for -8t

[tex]-8t = -3[/tex]

Solve for t

[tex]t = \frac{-3}{-8}[/tex]

[tex]t = 0.375s[/tex]

Answer:

C

Step-by-step explanation:

7 - 3 = 4 = Length

3 + c = ? = w

A = 32

32 ÷ 4 = 8 = w

8 - 3 = 5 = number added to width

5 = c

Word explanation:

To find the number added, you have to figure out the length so that you could divide it by area to figure out the width.

So, to do that, you follow what the question said, "Three centimeters are subtracted from the length." = 7 - 3 = l = 4

Then, you move on to figure out the width, so you divide the area by the length = 32 ÷ 4 = 8 = width.

Now that you know the width, you continue to follow what the question said, "C centimeters are added to width."

= 3 (previous width) + c = 8 (new width)

After that, you subtract 8 - 3 to find the amount added to the width and that gives you 5, which is C.

The value of the variable c is 5 centimeters.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

To determine the number added, we have to figure out the length so that we could divide it by area to figure out the width.

"Three centimeters are subtracted from the length means;

= 7 - 3 = l = 4

Then, move on to figure out the width, so we divide the area by the length

= 32 ÷ 4

= 8  width.

Now that we know the width, continue to follow what the question said, "C centimeters are added to width."

= 3 (previous width) + c = 8 (new width)

After that, subtract 8 - 3 to find the amount added to the width and that gives 5, which is C.

Which two angles measures can u add to find the Measure of angle FMH? Pls

Pls help

Answer:

149.04 in^2

Step-by-step explanation:

The image of the question can be seen below.

In the image, we can see two circles that intersect at a given point.

We know that the total area of the image is 350 in^2

We want to find the area of the shaded part.

Ok, this seems to be hard, so instead, let's find the area of the two non-shaded parts (two semicircles) and just subtract that area from the total area of 350in^2

The two non-shaded parts are half a circle of diameter 16 inches.

We know that for a circle of diameter D, the area is:

A = pi*(D/2)^2

Where pi = 3.14

And because we want to find the area of two semicircles of diameter 16 inches, is exactly the same as finding the area for a single circle of diameter 16 inches.

This is:

A = 3.14*(16in/2)^2 = 3.14*(8in)^2 = 200.96 in^2

Now we can just subtract this from the total area:

shaded area = total area - A

shaded area = 350 in^2 - 200.96 in^2

shaded area = 149.04 in^2

Answer:

$ 10,000

Step-by-step explanation:

Manuel wants to replace the wooden floor at his gym. The floor is in the shape of a rectangle. Its length is 50 feet and its width is 25 feet.

The gym floor is shaped like a rectangle

Area of a rectangle = Length × Width

= 50 feet × 25 feet

= 1250 ft²

Suppose wood flooring costs $8 for each square foot.

The wood flooring cost for the floor is calculated as

1 ft² = $8

1250ft² = x

Cross Multiply

1250 ft² × $8

$ 10,000

The wood flooring cost for the floor is $10,000

[tex]x = 5016[/tex]

[tex]y = 1008[/tex]

Step-by-step explanation:

Given

Let:

[tex]x \to Elephant\ seal[/tex]

[tex]y \to Bennet[/tex]

From the first statement, we have:

[tex]x + y = 6024[/tex]

From the second, we have:

[tex]2x - y = 9024[/tex]

Required

Find x and y

Add both equations to eliminate y

[tex]x +2x + y - y = 6024 + 9024[/tex]

[tex]3x = 15048[/tex]

Divide both sides by 3

[tex]x = 15048/3[/tex]

[tex]x = 5016[/tex]

Substitute [tex]x = 5016[/tex] in [tex]x + y = 6024[/tex]

[tex]5016 + y = 6024[/tex]

Solve for y

[tex]y = 6024 - 5016[/tex]

[tex]y = 1008[/tex]

you would subtract 5x from 2x and get -3x+10 < 1

then subtract 10 from 1 and get -9 so

-3x<-9 then divide and flip sign x>3 hope this helps

Answer:

x>3

Step-by-step explanation:

1.subtract both sides

2x+10 -5 < 5x+1 -5

-3x+10<1

2.subtract 10 from both sides

-3x+10 -10 < 1 -10

-3x<-9

3.divide both sides with number including x

-3x < -9

-3      -3
