what is the hypotenuse?

Answer:

The answer is 1.86x10 6

Step-by-step explanation:

10x6 is 100k and the speed light travels is 186k so to get the answer you need to find the one that gets to 100k and then multiply it by 1.86

Answer:

1.478 kg

Step-by-step explanation:

Considering density=mass/volume, when we rearrange, we get mass=density*volume. Therefore, as we are given the density, we just need to find the volume to know the mass. The volume of a cylinder is πhr^2, and our radius is 28/2=14, so the volume of the cylinder is π*3*14^2=588π. Then, 588π*0.8=470.4π which is about 1477.8052 g. Then, to convert to kg, we can divide this by 1000 and get about 1.478 kg.

The dimensions of the rectangle are 6 and 3.5 ft.

Let the width of rectangle be x. So, the length of the rectangle will be 2x - 1. As per the known fact, the area of rectangle is given by the formula -

Area = length × breadth

Keep the values in formula to find the dimensions of the rectangle

x(2x - 1) = 21

Performing multiplication on Left Hand Side of the equation

2x² - x = 21

Rewriting the equation

2x² - x - 21 = 0

On factorizing we get, x = -3 and 3.5.

The dimensions of rectangle can not be negative, this, taking the value of x as 3.5. Now, the width of rectangle will be 3.5.

Length of rectangle = (2×3.5 - 1)

Length of rectangle = 7 - 1

Length of rectangle = 6

Thus, the length and width is 6 and 3.5 ft respectively.

56% interest rate, to the nearest hundredth of a percent, would be necessary for Amira to end up with $840 assuming the interest is compounded continuously.

Given that,

Amira will put $580 into an account and let it sit there for 17 years.

We have to find what interest rate, to the nearest hundredth of a percent, would be necessary for Amira to end up with $840 assuming the interest is compounded continuously.

We know that,

We have a formula

A=P(1+r/n[tex])^{nt}[/tex]

Here,

A=$840

P=$580

Answer:

m∠B = 121°

Step-by-step explanation:

[tex]10x-19=9x-5[/tex]  

[tex]10x=9x+14[/tex]  (add 19 on both sides)

[tex]x=14[/tex]  (subtract 9x on both sides)

[tex]9(14)-5 = 126-5=121[/tex]  

Answer: m∠B=121°

Step-by-step explanation:

The opposite angles of the parallelogram are equal

Hence,

(10x-19)°=(9x-5)°

10x-19=9x-5

10x-19-9x=9x-5-9x

x-19=-5

x-19+19=-5+19

x=14

Hence,

m∠B=(9(14)-5)°

m∠B=(126-5)°

m∠B=121°

A triangle has two sides of length 18.9 and 2.9. inequality which describes the possible lengths for the third side, x is 16 < x < 21.8

The triangle inequality theorem states that,

given two lengths of the sides of a triangle, the length of the third side of the triangle must be greater than the difference and less than the sum of the two given sides.

For the two sides a and b of the triangle, the third side c must follow as follows:

(a - b) < c < (a + b)

So let a = 18.9 and b = 2.9

let the length of third side of triangle be x then

(18.9 - 2.9) < x < (18.9 + 2.9)

=> 16 < x < 21.8

So , the third side of the triangle must follow the inequality 16 < x < 21.8

Three  pairs of fractions that have a sum of 5/6 are;

1/3 + 2/3 = 5/6

1/4 + 3/4 = 5/6

2/6 + 3/6 = 5/6

1/3 + 2/3 = 5/6: The fractions have a common bottom number of 3 because they both have the same bottom number.

Adding the top numbers: 1 plus 2 equals 3.

The total is three divided by three, which can also be written as one.

However, we need to show the total with a bottom number of 6 to match the original part. So, we make the top and bottom numbers twice as big to get 2/6. Hence , 1/3 + 2/3 = 2/6.

1/4 + 3/4 = 5/6:The fractions have the same bottom number, so their common denominator is 4.

When you add 1 and 3 together, you get 4.

The sum is four over four, and when simplified, it equals one.

Once again, we have to find a way to write the sum with a bottom number of 6 so that it is the same as the first number in the fraction. So, we take the top number and the bottom number and multiply them both by 3 to get the fraction 3/6. Hence, 1/4 + 3/4 = 3/6.

2/6 + 3/6 = 5/6:In this situation, the fractions already have the same bottom number which is 6.

Adding the top numbers together: 2 + 3 = 5.

The answer is 5/6, which is what we wanted to get.

Therefore each pair shows a different way to add numbers together, either by finding a number that both denominators can divide evenly into or by using numbers that already work well together.

Answer:

To represent the area of a stained-glass mosaic that sits under a parabolic arch, we can use the equation for a parabolic arch, which is of the form

y = a(x - h)^2 + k

where (h,k) is the vertex of the parabola. The width of the parabolic arch at the base is 8 feet, so the vertex of the parabola is located at (4,0). Therefore, the equation for the parabolic arch is

y = a(x - 4)^2

The height of the parabolic arch is 10 feet, so we can represent the area of the stained-glass mosaic as the region where y is between 0 and 10. This can be expressed as the inequality

0 ≤ a(x - 4)^2 ≤ 10

Solving this inequality for x gives us the solution
