Answer:

SA = 578ft²

Step-by-step explanation:

First, we have to know the formula of finding the surface area of a rectangular prism.

Formula: 2(wl + hl + hw)

w = width l = length h = height

Next, we separate the composite figure into two rectangular prisms.

Since we have all measurements, let's use that to find the SA.

The first shape (to the left)

SA = 2(wl + hl + hw)

SA = 2(4 x 9 + 9 x 9 + 9 x 4)

SA = 2(36 + 81 + 36)

SA = 2(153)

SA = 306

Then, we do the other shape(to the right)

We know the measurement of length = 4 because it is the same measurement as the width

SA = 2(wl + hl + hw)

SA = 2(4 x 4 + 15 x 4 + 15 x 4)

SA = 2(16 + 60 + 60)

SA = 2(136)

SA = 272

Lastly, we add those two

306 + 272 = 578

Therefore, SA = 578ft²

Answer:

n = 18

Step-by-step explanation:

Hi there!

\(\displaystyle\frac{n}{30}=\frac{60}{100}\)

Isolate n by multiplying both sides by 30:

\(\displaystyle\frac{n}{30}*30=\frac{60}{100}*30\\\\n=\frac{1800}{100}\)

Simplify the fraction:

\(\displaystyle n=\frac{18}{1}\\\\n=18\)

Answer: 6 lenses

Step-by-step explanation:

1 pair of glass=2 lenses

3 glasses=3 pair of glasses

3 pairs of glasses*2 lenses/1 pair of glass=6 lenses in 3 pair of glasses

Answer:

6

Step-by-step explanation:

A pair of glasses usually contains 2 lenses. The equation y=2(x) is equal to the amount of lenses she would have. If y=total lenses and Mariana has 3 pairs then that means y=2(3) and 2(3)=6. Therefore y=6.

This is assuming that the glasses are single lense.

Step-by-step explanation:

0.5% of w is 12 is what they are asking

0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is

\(12 = 0.005 \times w\)

Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite

\(w = \frac{12}{0.005} = 2400\)

Answer:

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

Answer: 1/(x^6)

Step-by-step explanation:

(x^-2)^3=

(x^(-2*3))=

(x^(-6))=1/(x^6)

Answer:

1/\(x^{6}\)

Step-by-step explanation:

(x^-2)^3

If you have parentheses around an exponent, you multiply them together.

x^-6

Change it to reciprocal so it is 1/\(x^{6}\)

Proof:

\(x^{-2}\) × \(x^{-2}\) × \(x^{-2}\) = \(x^{-2 - 2 - 2}\) = \(x^{-6}\)

Answer:

35 x (-4x) = -1           (9 hours)

Step-by-step explanation:

If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.

35 x (-4x) = -1

-4x = -36

x =  9

35 x (-4x) = -1  (9 hours)

Step-by-step explanation:

If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.

35 x (-4x) = -1

-4x = -36

x =  9

Answer:

42°

Step-by-step explanation:

This is defined as a transversal in geometry, where one line intersects two straight lines.

It is given that one of the angles is 42°. Let the angle that measure 42° be denoted as ∠42.

∠4 ≅ ∠42 based on the alternate interior angles theorem.

∠4 ≅ ∠7 based on the vertical angles theorem.

Therefore, ∠42 ≅ ∠7 based on CPCTC.

Therefore,

m∠7 = 42°.

Answer:

One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction

Step-by-step explanation:

1/5^4 = 1/5 * 1/5 * 1/5 *1/5 = 1/625

The expanded form of (One-fifth)⁴ is "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction," and its value is "StartFraction 1 Over 625 EndFraction."

              The expanded form of (One-fifth)⁴ can be derived by multiplying (1/5) four times. Each multiplication represents multiplying by one-fifth, resulting in "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction." This can be further simplified as "StartFraction 1 Over 625 EndFraction" by multiplying the numerators and the denominators separately.

              In mathematical terms, when we raise one-fifth to the power of 4, we are essentially multiplying one-fifth by itself four times. Thus, (One-fifth)⁴ is equal to "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction."

            Evaluating this expression yields the value "StartFraction 1 Over 625 EndFraction" since multiplying the numerators (1 * 1 * 1 * 1) and the denominators (5 * 5 * 5 * 5) results in 1 and 625, respectively.

           Mathematical representation:  \(\frac{1}{5}^4= \frac{1}{5} * \frac{1}{5} * \frac{1}{5} * \frac{1}{5}\)

Answer:

The perimeter of the rectangle is 84 cm.

Step-by-step explanation:

From X=-17 to X=8 is 25 cm.

From Y=12 to Y=-5 is 17 cm.

Therefore, the equation is 2(25) + 2(17) = 84

The perimeter of the rectangle is 84 cm.

We need to find the length and width of the rectangle first, and then use the formula for the perimeter, which is P = 2(l + w).

The length of the rectangle is the distance between the points (-17, 12) and (8, 12), which is 8 - (-17) = 25 units.

The width of the rectangle is the distance between the points (-17, 12) and (-17, -5), which is 12 - (-5) = 17 units.

Using the formula for the perimeter of a rectangle, we have:

P = 2(l + w) = 2(25 + 17) = 84 cm

Therefore, the perimeter of the rectangle is 84 cm.

Answer:

let's say cells is c and hours are x that means there are 15 cells each hour. the equation for that is c=15x

after 08 hours the cells have multiplied 8 times their original size. meaning that the equation changes to this: c=15x          x=8    c= 15(8)

x equals 8 at that time.. literally

ok the cells have multiplied and now there are 120 cells in total

then after one day the cells have multiplied over 12 times afterwards. now x equals 24. the equation would look a little like this:

c=15x      x=24    c= 15(24)

there are 360 cells now.

Explain in your own words the relationship between x=8 with x=24 in the equation.
