Answer:

<h3>The answer is option A.</h3>

Step-by-step explanation:

To solve the question we use the following conversion

1 feet per second = 1.09728 kilometers per hour

Therefore 11 ,000 feet per second is

$11000 \times 1.09728$

We have the final answer as

<h3>12070.08 kilometers per hour</h3>

Hope this helps you

Make x the subject of the formula: <br> Y=3x^2+4

Rzqust [24]

Answer:

see explanation

Step-by-step explanation:

given

y = 3x² + 4 ( isolate the term in x by subtracting 4 from both sides )

y - 4 = 3x² ( divide both sides by 3 )

$\frac{y-4}{3}$ = x² ( take the square root of both sides )

$\sqrt{\frac{y-4}{3} }$ = x, or

x = $\sqrt{\frac{y-4}{3} }$

Billy has 1 gallon of paint. He is going to pour it into a paint tray that measures 10 inches wide, 14 inches long, and 4 cm dee

V125BC [204]

Answer:

The paint will not fill the tray by 10.53 cubic inches.

Step-by-step explanation:

We will find the volume of the paint tray and compare it with the volume of the gallon.

Given dimensions are:

Length = 14 inches

Width = 10 inches

Depth = 4 cm or $\frac{4}{2.54}=1.575$ inches

The volume is given by = length x width x depth

Volume = $14\times10\times1.575=220.50$ cubic inches

Volume of 1 gallon is given as = 231 cubic inches

We can see that volume of 1 gallon is more than volume of tray.

Difference = $231-220.50=10.5$ cubic inches.

So, the paint will not fill the tray by 10.53 cubic inches.

Please help. Will give brainliest. And I need step by step please

Elan Coil [88]

Answer: 500cm squared

Step-by-step explanation:

To figure out the area, here are the steps

First, seperate the parallelogram into 2 triangles and a rectangle.

Secondly, we see it has figured out the area of the triangle which is 25, so we can assume that the other triangle is also 25. So the area of the two triangles are 25 + 25 = 50

Then, if we look at what it has labeled, we would know that the length of the parallelogram is 50, BUT this 50 contains ONE length of the triangle, which means to get the actual length of the rectangle, we must subtract a length of a triangle from 50.

That's 50 - 5 = 45. Therefore the area of the rectangle is (length times width) 45 ✕ width = the area of the rectangle.

Now we realize that we don't know the width of the rectangle, we can figure that out by back-tracking from the area of the triangle.

We know that area of a triangle is length times height divided by 2, so 25 ✕ 2 divided by legth would get us the height of the triangle. 25 ✕ 2 ÷ 5 = 10

Now we can figure out the area of the rectangle. 45 ✕ 10 = 450

Add the rectangle and the triangles together, you get -- 450 + 50 = 500 (cm squared）

Sally invests $10,500 in an account that earns 6% annual simple interest. Assuming she makes no additional deposits or withdrawa

Fittoniya [83]

Answer: $2520

Step-by-step explanation:

The simple Interest earned on a deposit of P that has a rate of r% and a period of t years can be calculated by using the formula:

(P × R × T)/100

where P is principal

R is rate

T is time

P=$10,500

R=6%

T=4 years

Therefore:

Interest= (10500 × 6 × 4)/100

= 252000/100

= 2520

Sally will earn $2520 as interest after 4 years.
