what is 4/5+(−7/5)?
(it's in fraction form)

Answer:

C

Step-by-step explanation:

Follow Pythagorean Theorem. a^2 + b^2 = c^2

We know b and c:

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = √25

a = 5

The answer is C because we know side a = 5

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer:

Crayola Classic: 5 Packs; Crayola Tropical: 4 Packs

Step-by-step explanation:

Keep multiplying by both until you get a number equal to eachother

1. 8 x 2 = 16,  10 x 2 = 20

2. 8 x 3 = 24, 10 x 3 = 30

You may notice that the numbers are getting farther apart. This is normal because the boxes are not equal and are getting multiplied further. That means that your answer will have different factors in both the equations.

3. 8 x 4 = 32, 10 x 4 = 40

4. 8 x 5 = 40

Both of those equations (in bold) have the same answer and he wanted the same crayons from both. So, the answer is:

10 x 4 = 40

8 x 5 = 40

Answer:

Time = 1.27 x 10^1 minutes

Step-by-step explanation:

To calculate the approximate amount of time it takes for light to travel from the Sun to Mars, we can divide the distance between them by the speed of light.

Given:

Speed of light = 1.12 x 10^7 miles per minute

Distance between the Sun and Mars = 1.42 x 10^8 miles

Time = Distance / Speed

Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)

Time = (1.42 / 1.12) x 10^(8 - 7) minutes

Time = 1.27 x 10^1 minutes

Rounded to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.70 minutes in scientific notation.

The length of segment NB is 0.833

From the question, we have the following parameters that can be used in our computation:

The rectangle

The area of the rectangle is

Area = (20 + x) * 10

The area of MNBC is

Area  = 1/2 * 10 * (x + 20 + x - 5)

Area  = 5(2x + 15 )

The area of the quadrilateral MNBC is 40% of the total area of the rectangle

So, we have

5(2x + 15) = 40% * (20 + x) * 10

5(2x + 15) = 4* (20 + x)

When evaluated, we have

x = 0.833

Answer:

X=1

Step-by-step explanation:

The total area of the rectangle is 20x10=200

so the area of MNBC is: 40%x200=80

MC= 20-5=15

so (x+15).10/2=80 (according to the trapezoidal area formula)

x=1

Answer:

-----------------------------------

The two angles with the variable x form a linear pair and therefore:

Angles 16x - 18 and 12y are congruent as vertical angles:

Answer:

x = 7.5

y = 8.5

Step-by-step explanation:

Linear Pair

Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).

To find x, equate the sum of the two angles with the variable x to 180° and solve:

⇒ (16x - 18)° + (10x + 3)° = 180°

⇒ 16x - 18 + 10x + 3 = 180

⇒ 26x - 15 = 180

⇒ 26x = 195

⇒ x = 7.5

Vertical Angles Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Therefore:

⇒ (16x - 18)° = 12y°

Substitute the found value of x into the equation and solve for y:

⇒ 16x - 18 = 12y

⇒ 16(7.5) - 18 = 12y

⇒ 120 - 18 = 12y

⇒ 102 = 12y

⇒ y = 8.5

Answer:

Step-by-step explanation:

Given a model has a scale factor of 2:15 with respect to the original car, you want to know the ratios of model : original for width, volume, and surface area.

The scale factor is the ratio of linear dimensions, such as width. This means the ratio of widths will be 2:15, the same as the scale factor.

Areas have units of the square of a linear dimension. Hence the ratio of areas is the square of the ratio of linear dimensions, the square of the scale factor. The ratio of surface areas will be 2²:15² = 4:225.

Volumes have units of the cube of a linear dimension. Hence the ratio of volumes is the cube of the ratio of linear dimensions, the cube of the scale factor. The ratio of volumes will be 2³:15³ = 8:3375.

The model : original ratios are ...

Step-by-step explanation:

If the drama club spent $8.50 per person on food, and if the total cost of food was $229.50. How many people were at the cast party?

To find how many people are there, we need to divide $229.50 to $8.50.

$229.50 ÷ $8.50 = 27

Answer:

27 people

Step-by-step explanation:

229.50/8.50=27

Answer:

45 degrees

Step-by-step explanation:

OK so

is L and N are equal you can represent that as 2x

the remaining angle should be 90 because right triangles always have a 90 degrees angle somewhere

you know that all three angles of a triangle add up to 180 so that's what the total is

2x+90=180

subtract 90 from both sides

2x=90

divide both sides by 2

x=45
