Answer:

10/k=8/4

10*4=8k

K=40/8

K=5

Hey there!

“10 / k = 8 / 4”

FIRST: CROSS MULTIPLY

10(8) = 4(k)

10(8) = 80

4(k) = 4k

NEW EQUATION: 80 = 4k

SECOND: FLIP/TURN the EQUATION

4k = 80

THIRD: DIVIDE both SIDES by 4

4k / 4 = 80 / 4

CANCEL: 4 / 4 because that gives you 1

KEEP: 80 / 4 because that gives you the value of k

NEW EQUATION: 80 / 4 = v ; v = 80 / 4

FOURTH: SOLVE above and you have the k-value

Answer:

k = 5☑️

Good luck on your assignment and enjoy your day!

Answer:

2^27

Step-by-step explanation:

Given the following expression:

[(2^10)^3 x (2^-10)] ÷ 2^-7

This can be easily simplified. Let us simplify the numerator first. To do that, we have

(2^10)^3 making use of the power rule of indices that says:

(A^a)^b = A^ab where a and b are powers, we have:

2^(10x3) = 2^30

Therefore the numerator becomes:

2^30 x 2^-10. Also making use of the multiplication rule that says:

A^a x A^b = A^(a + b), we have

2^30 x 2^-10 = 2^(30 – 10) = 2^20.

Now we have:

(2^20) ÷ (2^-7)

To simplify this, we need the division rule of indices which says:

A^a ÷ A^b = A^(a – b)

Therefore we have:

(2^20) ÷ (2^-7) = 2^[20 – (–7)] = 2^(20+7) = 2^27

Following are the solution to the given expression:

Given:

[tex]\to \frac{[(2^{10})^3 \times (2^{-10})]}{2^{-7}}[/tex]

To find:

value=?

Solution:

[tex]\to \frac{[(2^{10})^3 \times (2^{-10})]}{2^{-7}}[/tex]

Using formula:

[tex]\to (A^a)^b = A^{ab}\\\\\to A^a \div A^b = A^{(a - b)}[/tex]

Solve the equation:

[tex]\to \frac{[(2^{30}) \times (2^{-10})]}{2^{-7}} \\\\\to \frac{(2^{30})}{2^{-7}} \times \frac{(2^{-10})}{2^{-7}} \\\\ \to \frac{(2^{30})}{2^{-7}} \times \frac{(2^{-10})}{2^{-7}} \\\\\to (2^{30 - (-7)}) \times (2^{-10- (-7)}) \\\\\to 2^{37} \times 2^{-3} \\\\\to 2^{37 -3} \\\\\to 2^{34} \\\\[/tex]

Therefore, the final answer is "[tex]\bold{2^{34}}[/tex]".

Answer:1.b 2.c 3.a

Step-by-step explanation:

The percent of increase is 10% or 5. If you multiply 20 x 0.1, you get 2. Then, you add 20 and 2 together to result with $22. Therefore, the answer is 10% or a 10% increase.

Question:

The probability of rolling a number less than 3 on a number cube is 2/6 . Jennifer rolls a number cube 60 times. How many times should Jennifer expect to roll a number less than 3?

Answer:

The expected value is 20

Step-by-step explanation:

Given

[tex]n= 60[/tex] --- Number of rolls

[tex]p = \frac{2}{6}[/tex] -- probability

Required

Determine the expected value

Expected value (E(x)) is calculated using:

[tex]E(x) = n * p[/tex]

Substitute values for n and p

[tex]E(x) = 60 * \frac{2}{6}[/tex]

[tex]E(x) = \frac{120}{6}[/tex]

[tex]E(x) = 20[/tex]

Step-by-step explanation:

In the trapezoid , PQ || MN. Taking PN as transversal , we can say that QPN and MNP are supplementary angles.

[tex] = > 3x + 5 + 8x - 12 = 180[/tex]

[tex] = > 11x - 7 = 180[/tex]

[tex] = > 11x = 180 + 7 = 187[/tex]

[tex] = > x = \frac{187}{11} = 17[/tex]

Answer:

The price is now $44

Step-by-step explanation:

The original price is $55

The discount percent is20%

Calculate the savings: 20% of $55 = $11

Subtract the savings from the original price to get the sale price: $55 - $11 = $44

Answer:

that could be any number

Step-by-step explanation:

There is not enough information to find out the exact amount so this could be any number.

Answer:

2339

Step-by-step explanation:

the answer is a because you have to find the slope.

Answer:

2x+3=4

2x=1

x=0.5

.....

Step-by-step explanation:

Hence it is a triangle So sum of all the angels of triangle is equal to 180°

Then

5x + 6x + x = 180°

12x = 180°

x = 180° / 12

x = 15°

5x = 5*15°= 75°

6x = 6* 15° = 90°

x = 15°

Answer: 5

Step-by-step explanation:

If you use long division you will get 5.

The explanation behind  the area of a rectangle increases by a factor of 4 when the side length is doubled is due to the fact that;

The length and width are double which translates to a product of 4 which means the area will increase by a factor of 4.

We know that area of a rectangle is;

A = length x width

Now, let us say we have a sample rectangle with length of 7 cm and width of 3 cm.

This means area is; A = 7 x 3 = 21 cm²

Now, if we double the side lengths, it means our length is now 7 x 2 = 14 cm² and width now 3 x 2 = 6

Our new area is now 14 x 6 = 84 cm²

If we look at the initial area we will see that it has been increased by a factor of 4 to obtain 84.

All of them are the same length because if you see the picture the red dot is in the middle of the circle so that's how there all the same length.

Step-by-step explanation:

Circumference of the circle

= 2πr = (2)(π)(12 in) = 24π in.

Length of arc ABC

= 24π in * (210°/360°)

= 14π in

= 43.98 in.

Hey, I'm using edmuentum too, just so you know, you only have to do the tutorials unless you get the Mastery test wrong. I normally just skip through them and just get the questions wrong since the teachers can't see your answers on the tutorials. :) Anyways the answer is:

The first is growth by 25%

The second is decay by 25%

The third is growth by 100%

The fourth is growth by 1%

The last is decay by 1%
