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

29.2

Step-by-step explanation:

15×15=225

25×25=625

225+625=850

the square root of 850 is 29.2

240/4=60

1:3

60*3=180

Answer= 60:180

Answer:

60:120

Step-by-step explanation:

You need to add the two parts of the ratio

1+3=4

Then you divide 240 by 4

240 divided by 4= 60

Then you do :

60x1= 60

60x3= 120

There you go, you have your answer.

Answer:

w=2

Step-by-step explanation:

A=length times width (A=lw)

w= l-3

A=10

Substituting in, we get:

10= l(l-3)

Now, solve the equation.

10= [tex]l^{2}[/tex]-3l

[tex]l^{2}[/tex]-3l-10=0

(l+2) (l-5)=0 (factoring the equation)

Therefore, l= -2 or 5

Throw out the negative value because a length of rectangle will never be negative.

Now let's solve for width

Remember w=l-3

therefore

(5)-3=2

so, w=2

(honestly, this is easier to just do in your head. But here is the long form math if you happen to run into more complicated problems.)

Answer:

w=2 l=5

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.

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]

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

Answer:

D

Step-by-step explanation:

If 2 tangents are drawn to a circle from the same external point then they are congruent.

AG and AE are tangents to the circle from the same external point, thus

AG is congruent to AE

AG is congruent to AE. Then the correct option is D.

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

If two tangents are drawn to a circle from the same external point then they are congruent.AG and AE are tangents to the circle from the same external point.

Answer:

-5.95 on edge

Step-by-step explanation:

The absolute magnitude of a star that has a period of 45 days is -5.95.

magnitude, in astronomy, measures the brightness of a star or other celestial body. The brighter the object, the lower the number assigned as a magnitude. In ancient times, stars were ranked into six magnitude classes, the first magnitude class containing the brightest stars.

Mv = m - 2.5 log[ (d/10)2 ]. Stars farther than 10 pc have Mv more negative than m, that is why there is a minus sign in the formula. If you use this formula, make sure you put the star's distance d in parsecs (1 pc = 3.26 ly = 206265 AU).

The absolute magnitude of a 45-day star is -5.95.

The magnitude measures the brightness of a star or other celestial body in astronomy. The brighter the object, the lower the number assigned as a magnitude. In ancient times, stars were divided into six magnitudes, the first of which contained the brightest stars.

Mv = m-2.5log [(d / 10) 2]. Stars over 10 pc have a minus sign in the formula because Mv is more negative than m. When using this formula, enter the star distance d in parsecs (1 pc = 3.26 Ly = 206265 AU).

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:

(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

Step-by-step explanation:

Mike buys 3 cans of pop per week and this is one more than 2/5 of the number of cans of juice that he buys.

Let the number of cans of juice be j and let the number of cans of pop be buys be p.

This means that:

p = 1 +2j/5

Make j subject of formula:

p - 1 = 2j/5

=> 2j = 5p - 5

j = ½(5p - 5)

p = 3 (from the question)

Therefore:

j = ½(5 * 3 - 5) = ½(15 - 5)

j = ½ * 10 = 5

Mike buys 5 cans of juice per week.

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
