Answer:

h to the power of 7 im pretty sure

Step-by-step explanation:

Answer:

h^7

Step-by-step explanation:

h^6 . h

h can be written as h^1

Formula : -

a^m . a^n = a^( m + n )

Here,

a = h

m = 6

n = 1

h^6 . h^1

= h^( 6 + 1 )

= h^7

Here is how to solve these!

if u want me to solve them too, tell me in the comments.

Step-by-step explanation:

So, u start off by putting in ur mind that u want to solve for x (or the variable) and u start working on that by that following:

-Step one: Isolate the variable, u should remove anything that is at the same side of the equal sign along with the variable to the other side, you do that by flipping the operation in front of it (flip + to -, flip x to /, and vice versa too) for example, you have 3x=6, u isolate x by dividing 3 by both sides, removing it from the side of x and taking it to the other side.

-Step two: After moving the numbers to the other side, make the operation u should be doing, example is now that u have x= 6/3 u won’t leave it standing there, so u solve, and the answer would be 2

-Step three: Piece everything together, now that u have a side with only one number and a side with only a variable, you know what x really is, which is x=2 and this is how u find x

-Additional step: if ur teacher told u to check if ur answer is correct, u check by substituting the variable (x) with the answer u got (2) and solve the equation u had in the first place normally, if the two sides are equal, ur answer was correct, if they are not, u have to solve it again with more focus

ur welcome :)

If the two ends of this triangular right prism are equilateral triangles. The surface area of the prism is 74cm.

Using this formula

A=bh+L(S1+S2+S3)

Where:

L=5cm

b=4cm

h=3.5cm

S1=4cm

S2=4cm

S3=4cm

Let plug in the formula

The congruency statements that are true if triangles JMN and KQR are congruent are:

A. ∠M ≅ ∠Q

E. QK ≅ MJ

F. MN ≅ QR

Two triangles that are congruent to each other will have their corresponding angles and corresponding sides congruent to each other.

Thus, since we assume that △JMN ≅ △KQR, all corresponding angles and sides of both triangles must be congruent.

Therefore, the true congruency statements are:

A. ∠M ≅ ∠Q

Answer:

Approximately 7.81 miles apart.

Step-by-step explanation:

If you were to draw lines between the three points, you would see that it makes a triangle, with leg lengths 6 and 5, like in the attached file.

To find the distance between Hillsboro and Middletown, or the hypotenuse of the triangle, use the Pythagorean Theorem:

6² + 5² = c²

c² = 61

c = √61 = 7.81 miles

Answer: No, the volume is eight times as large

Step-by-step explanation:

      We will test this. Let the radius equal 4, then we will double it to 8.

4 * 2 = 8

    With a radius of 4, the volume is about 268 units³. With a radius of 8, the volume is about 2,145 units³.

        2,145 / 268 = 8

The volume is not twice as large, it is eight times as large.

Why is this? In the formula, r is cubed. WIth an example of 2, 2 * 2 * 2 = 8.

Answer:

The correct option is "an angle measure with an arc length equal to one radius length"

Answer:

D) 56 inches to 74 inches

Step-by-step explanation:

By the Empirical Rule, 99.7% of data in a normal distribution spread across ±3σ standard deviations from the mean μ.

Hence, the range maximum is μ+3σ = 65+3(3) = 65+9 = 74 inches, and the range minimum is μ-3σ = 65-3(3) = 65-9 = 56 inches

Thus, 99.7% of the population will have a height within the range of 56 inches to 74 inches

The system of equation 2x + y = 2 y = –2x – 1 has infinitely many solutions because the coefficient of the x and y in the equations are same.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have a system of equations:

2x + y = 2  …(1)

y = –2x – 1  or

2x + y = -1 ...(2)

As we can see the coefficient of the x and y in the equation (1) and (2) are same which means they infinitely many solutions.

Thus, the system of equation 2x + y = 2 y = –2x – 1 has infinitely many solutions because the coefficient of the x and y in the equations are same.

Answer:

10 units.

Step-by-step explanation:

Given:

Formula:

[tex]\text{Volume of rectangular prism = Length} \times \text{Width} \times \text{Height}[/tex]

Substitute the length, width, and the volume of the prism in the formula

[tex]\implies \text{2500 = 25} \times 10 \times \text{Height}[/tex]

Divide 25 × 10 to both sides of the equation to isolate "Height"

[tex]\implies \dfrac{\text{2500}}{25 \times 10} = \dfrac{25 \times 10 \times \text{Height}}{25\times 10}[/tex]

[tex]\implies \dfrac{\text{2500}}{25 \times 10} = \text{Height}[/tex]

Simplify the left hand side of the equation

[tex]\implies \dfrac{{25 \times 10 \times 10}}{25 \times 10} = \text{Height} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [2500 =25 \times 10 \times 10][/tex]

[tex]\implies \dfrac{{10}}{1} = 10 = \text{Height}[/tex]

Therefore, the measure of the height is 10 units.

Answer:

1/4

Step-by-step explanation:

2 to the power of -2 would be 1/4.

This is because 2 to the power of -1 would be 1/2. And the power of 2 would square the 2 as the denominator making it 1/4.

The reason -1 makes the 2 turn into a fraction is that to the power of 2 means 2x2, to the power of one means 2, The power of zero would therefore divide by 2 so 2/2 = 1 and so 2 to the power of -1 would be 1/2.

The formula for the surface area of a rectangular prism (the storage box) is given by: A=2(wl+hl+hw). In this instance, w = width, h = height, and l = length.

We will calculate the surface area of the box and lid by first determining the height with the storage box lid included.

The height is now 40 cm (= 30 + 10). The width is still 45 cm. The length is still 60 cm.

You can fill in these values: A = 2(wl+hl+hw) = 2((45 * 60) + (40 * 60) + (40 * 45)) = 13,800.

Answer:

40

Step-by-step explanation:

The number of sides also represents the number of angles.

Now, to find the measure of one angle we will need to find the sum of angles first and to do that, we use this very simple formula:

(n-2)*180 (n is the count of interior angles)

7*180 = 1260 and to find the measure of one angle we divide the sum with the number of angles:

1260/9 = 140

now, since the sum of an interior angle and an exterior angle is 180:

180-140 = 40 is the size of one exterior angle

There's an easier way too, just divide the sum of exterior angles by the number of angles

360/9 = 40

Answer:

8.7%

Step-by-step explanation:

Well the net sales of Quarter 1 = 115 whilst the net sales of Quarter 2 = 125.

So the difference in the 2 numbers is 125-115 = 10

To find percentage change, you do 10/115 = 0.0869565217

Then, 0.0869565217 x 100 = 8.7% change to 1 decimal point.

So your percentage change is 8.7%.
