Answer:

Hi there!

The correct answer will be D. 7

Step-by-step explanation:

This is an example of the power rule where: [tex](a^{x} )^{y}[/tex] = [tex]a^{xy}[/tex]

1/5 multiplied by 5 equals 1, and anything with the exponent of one is itself so it's 7

Answer:

y = -22/5

Step-by-step explanation:

-3+7y=5x+2y

Subtract 2y from each side

-3+7y-2y=5x+2y-2y

-3 +5y = 5x

Add 5 to each side

5y = 5x+3

Divide each side by 5

y = 5x/5 +3/5

y = x +3/5

Let x = -5

y = -5 + 3/5

y = -25/5 +3/5

y = -22/5

Answer:

[tex]y=-\frac{22}{5}[/tex]

Step-by-step explanation:

[tex]-3+7y=5x+2y\\x=-5[/tex]

Replace:

[tex]-3+7y=5(-5)+2y\\-3+7y=-25+2y[/tex]

Subtract -2y

[tex]-3+7y-2y=-25[/tex]

Add 3

[tex]7y-2y=-25+3[/tex]

Combine like terms;

[tex]5y=-22[/tex]

Divide by 5.

[tex]y=-\frac{22}{5}[/tex]

Proof

[tex]For x=-5, y=-\frac{22}{5}[/tex]

[tex]-3+7y=5x+2y[/tex]

[tex]-3+7(-\frac{22}{5} )=5(-5)+2(-\frac{22}{5} )[/tex]

[tex]-3-\frac{154}{5}=-25-\frac{44}{5}[/tex]

To make it easier to solve, add 154/5

[tex]-3=-25-\frac{44}{5}+\frac{154}{5}[/tex]

Now add 25

[tex]-3+25=-\frac{44}{5}+\frac{154}{5}[/tex]

Combine like terms;

[tex]22=\frac{110}{5} \\22=22[/tex]

According to this question

new value = 63

old value = 90

Inputing these values we have ;

(63-90)/63 * 100

-27/63 * 100%

Answer:

C. 6

Step-by-step explanation:

Multiply the exponents on the expression

1/4 x 4 = 1

This simplifies to 6^1 or 6

Answer: C

Step-by-step explanation:

Since we are looking at a vertical and horizontal line, we can eliminate B and D. A and C would both be correct, but the most accurate description would be C. x=-2 and y=5 are perpendicular lines. Since one is horizontal and the other is vertical, it makes a perfect 90°.

Answer:

x = 12

Step-by-step explanation:

Given

[tex]\frac{3x}{6}[/tex] + 2 = 8 ( subtract 2 from both sides )

[tex]\frac{3x}{6}[/tex] = 6 ( multiply both sides by 6 )

3x = 36 ( divide both sides by 3 )

x = 12

Answer:

x = 12

Step-by-step explanation:

[tex] \frac{3x}{6} + 2 = 8 \\ collect \: like \: terms \\ [/tex]

[tex] cross \: multiply \\ \frac{3x}{6} = \frac{6}{1} \\ 3x = 6 \times 6 \\ 3x = 36[/tex]

[tex]divide \: both \: sides \: of \: the \: equation \: by \: 3 \\ \frac{3x}{3} = \frac{36}{3} \\ x = 12[/tex]

Answer:

10

Step-by-step explanation:

Answer:

(2) 22

Step-by-step explanation:

In the given triangle MNP, the medians are straight lines drawn from the angle to opposite side so as to divide the side into equal parts.

PS = 8 and QS = 3, thus;

PS = NS = 8 (congruent property of ΔRSN and ΔQSP)

QS = SP = 3 (congruence property)

So that,

NQ = NS + SQ

     = 8 + 3

    = 11

PR = PS + SR

    = 8 + 3

   = 11

Thus;

NQ + PR = 11 + 11

             = 22

Therefore, NQ + PR = 22

Answer:

120 cubes

Step-by-step explanation:

First we need to find the volume of the box and the volume of the cube.

Volume of box = 4 * 2.5 * 1.5 = 15 cubic units

Volume of cube = 0.5 * 0.5 * 0.5 = 0.125 cubic units

Now, to find how many cubes can be packed inside the box, we just need to divide the volume of the box by the volume of the cube:

number of cubes = volume of box / volume of cube

number of cubes = 15 / 0.125 = 120 cubes

Answer:

Ashton read 62 pages over the three days

Step-by-step explanation:

Given;

Ashton read 12 pages on Friday

He read 3 times as many pages on Saturday = 3 x 12 pages = 36 pages

He read 14 more pages on Sunday

The total number of pages read Ashton over the three days can be calculated as follows;

Total pages read by Ashton = 12 pages + 36 pages + 14 pages

Total pages read by Ashton = 62 pages

Therefore, Ashton read 62 pages over the three days

The airplane's path is an illustration of right-triangles

Represent the angle of descent with [tex]\theta[/tex]

The angle of descent, [tex]\theta[/tex] is then calculated using the following tangent identity

[tex]\tan(\theta) = \frac{35000\ feet}{150 \ miles}[/tex]

Convert feet to miles

[tex]\tan(\theta) = \frac{6.6287879\ miles }{150 \ miles}[/tex]

Divide

[tex]\tan(\theta) = 0.0442[/tex]

Take the arc tan of both sides

[tex]\theta = \tan^{-1}(0.0442)[/tex]

Evaluate the arc tan

[tex]\theta = 2.5[/tex]

Hence, the angle of descent is 2.5 degrees

Represent the plane's path with p

The plane's path is calculated using the following Pythagoras theorem

[tex]p^2 = (150\ miles)^2 + (35000\ feet)^2[/tex]

Convert feet to miles

[tex]p^2 = (150\ miles)^2 + (6.6287879\ miles)^2[/tex]

Evaluate

[tex]p^2 = 22543.940829[/tex]

Take the square roots

[tex]p = 150.15[/tex]

Hence, the plane's path is 150.15 miles

Answer: The rate of change is 5.

Step-by-step explanation:

Our equation is:

f(x) = x^2 + 4x + 5

And we want to find the rate of change in the range −1≤ x ≤2

when we want to find the rate between x1 ≤ x ≤ x2

we have:

Rate = (f(x2) - f(x1))/(x2 - x1)

So we have:

Rate = ( f(2) - f(-1))/(2 - 1)

Rate = (2^2 + 4*2 + 5 - (-1)^2 - 4*(-1) - 5)/3 = 15/3 = 5

The rate of change is 5.

Answer:

1/24

Step-by-step explanation:

In order to find the probability of a compound event, you have to multiply the probability of each event occurring together.

The probability of choosing a female is 1/2. There are only 2 genders.

The probability of choosing long hair is 1/3. There are three different lengths of hair to choose from.

The probability of choosing red hair is 1/4. There are four different hair colors to choose from!

Multiply all these probabilities:

1/2 * 1/3 * 1/4

= 1/24

Answer:

Angle y measures 130 degrees

Step-by-step explanation:

Notice that the angles marked as "2x+18", and "4x-14" must be equal angles since they are generated on the same sector (top right) of the parallel lines by the transverse line "b".

Then by finding the value of "x" we can deduce the value of the actual angle these two angles measure:

[tex]2x+18=4x-14\\18+14=4x-2x\\32=2x\\x=16^o[/tex]

Now, we can find the actual value of these two angles, we use for example the first expression:

Top-right angle = [tex]2\,(16^o)+18^o=50^o[/tex]

Now, if these two angles measure [tex]50^o[/tex], then angle "y" (which is the supplementary angle (angle which added renders [tex]180^o[/tex] )  for them, must equal [tex]180^o-50^o=130^o[/tex]

Answer:

  Correct. He transformed the triangle according to the rule (x, y) → (–y, x)

Step-by-step explanation:

  F'(-2, 3), H'(-5, 4), G'(-2, 1)

Find

  Whether the triangle was correctly transformed using the rule ...

  (x, y) → (–y, x).

Solution

For point F, we have ...

  x = 3

  y = 2

Then the rule tells us the point F' should be ...

  F' = (-y, x) = (-2, 3)

This is the point Quinton found for F', so his transformation was correct. (We can similarly verify that H' and G' are also correct.)

Answer: the answer is D

Step-by-step explanation:

The Volume of Cylinder is 108 inch³.

Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it can occupy in three dimensions.

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

Given:

Base = 12 inch

Height = 9 inch

So, the Volume

= base x height

= 12 x 9

= 108 inch³

For 6 years:

[tex]50000*(1.04)^6=\$63266[/tex]

On average, you would have to be profiting:

[tex]\frac{63266}{6}=\$10544[/tex] per year

For 4 years:

[tex]50000*(1.04)^4=\$58492[/tex]

On average, you would have to be profiting:

[tex]\frac{58492}{4} = \$14623[/tex] per year.

It would be better to have the longer term option - although you will be paying off more in total, you would be paying off a smaller portion of your earnings.

However, you may want to pay off the loan faster as you would no longer have to worry about it, and it would be cheaper to pay off over the shorter period.
