Find two numbers whose square increased by 15 equals 8 times the number.

Answer:

x=9.5

Step-by-step explanation:

In order to find the answer, we know that 6x + 4x - 5 = 90

Next we want to combine like terms: 10x - 5 = 90.

Now we have to add 5 to 90 in order to get x on its own.  10x = 95

Now solve for x by dividing 95 by 10: x=9.5

Answer:

The answer is 20%.

Step-by-step explanation:

10/50= 10 divided by 50=.2

.2 times 100 (because percentages are out of 100) = 20

20% is your answer

Answer:

5/16

Step-by-step explanation:

As you can see in the 16 given possible outcomes, in 5 of them at least 3 coins land facing up. Since there are 16 outcomes in total, the probability that at least three coins land facing up is 5/16. Hope this helps!

Answer:

4

Step-by-step explanation:

You can cross multiply.

first i would simplify x/12=3/9 to x/12=1/3

so then it would be equal to x*3=1*12

then i would simplify it to 3x=12

then you solve for x and i would get 4

Answer:

x = 4

Step-by-step explanation:

[tex]\frac{x}{12} =\frac{3}{9} \\[/tex]

Simplify [tex]\frac{3}{9} = \frac{1}{3} \\[/tex]

Answer:

[tex]n[/tex].

Step-by-step explanation:

Assuming that [tex]n \in Z^{+}[/tex], then all number less than [tex]n+1[/tex] are

[tex]n+1-1=n[/tex]

Notice that the "plus one" indicates that the whole number shown by the expression [tex]n+1[/tex] indicates a whole number greater than [tex]n\\[/tex] by one unit. So, we just subtract one whole unit to achive a number less than the given expression.

Therefore, the answer is [tex]n[/tex].

Step-by-step explanation:

The distance between the points  (-3, -6) and (3, 2) is  10 units.

The distance formula between two points (x₁, y₁) and (x₂, y₂) is given by,

D = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1_)^2[/tex].

Given, We have to determine the distance between the points (- 3, - 6) and (3, 2).

Let, (x₁, y₁) is (- 3, - 6) and (x₂, y₂) is (3, 2).

Therefore,

D = [tex]\sqrt{(3 + 3)^2 + (2 + 6)^2[/tex].

D = [tex]\sqrt{(6)^2 + (8)^2[/tex].

D = [tex]\sqrt{(36 + 64)[/tex].

D = [tex]\sqrt{100}[/tex].

D = 10 units.

Answer:

392

Step-by-step explanation:

I got it correct! :)

The surface area of the design is 392 square inches.

The correct option is B.

A cuboid is a solid in three dimensions with six rectangular faces, eight vertices, and twelve edges. Three dimensions, including length, breadth, and height, define a cuboid. A cuboid with integer edges is referred described as being perfect.

Given:

The shape is a cuboid.

The surface area of the cuboid,

= 2lw+2lh+2hw,

where l is the length, w is the width and h is the height.

The height of the upper cuboid,

= 10-4 = 6 inches.

The surface area of the upper cuboid,

= 2lw+2lh+2hw

= 2(36) + 2(36) - 2(36)

= 144 square inches.

The surface area of the lower cuboid,

= 2lw+2lh+2hw

= 2(40) + 2(24) + 2(60)

= 248 square inches.

The total surface area,

= 392 square inches.

Therefore, the surface area of the design is 392 square inches.

Answer:

Perimeter = 55.1 ft

area = 236.625 ft2

Step-by-step explanation:

radius = 15 / 2 = 7.5

Perimeter = perimeter of 2 half circle + 4+4

                = perimeter of 1 circle +4 +4

                = 2*7.5* pi + 4 + 4 = 55.1 ft

area = area of 2 half circle + area of 1 rectangle

        = area of 1 circle + area of 1 rectangle

        = pi *7.5*7.5 +4*15

        = 236.625 ft2

The area of a base of the triangular prism is 20 square feet.

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

From the given figure, the dimensions of the base are 4 ft and 5 ft.

Here, the base is rectangle

We know that, the area of a rectangle is Length×Width

Answer:

Step-by-step explanation:

1. We know that the 2 lines are not parallel. If they were, it would be marked on the graph. Therefore, corresponding angles (5 and 6 in this case) are not equal.

2. Angles 1 and 2 are corresponding angles, and because the 2 lines are parallel, they must be equal. Therefore, ∠1 = ∠2 = 60°.

3. Some real-life examples of parallel lines could be the shelves of bookcases or the painted lines in a parking lot. I hope this helps you.

<GDH = 112°

<FDH = 192°

<FDE = 135°

Step-by-step explanation:

If DE bisects <GDH this means that <GDE = <EDH

Given <GDE = (8x+1)° and <EDH = (6x+15)° then;

8x+1 = 6x+15

8x-6x = 15-1

2x = 14

x = 7°

Since <GDH = <GDE + <EDH

<GDH = 8x-1+6x+15

<GDH = 14x+14

<GDH = 14(7)+14

<GDH = 98+14

<GDH = 112°

For <FDH,

Note that sum of angle on a straight line is 180°

<FDH = <FDG + <GDE + <EDH

<FDH = <FDG + <GDH

<FDG = 180-(43+8x+1)

<FDG = 180-44-8x = 136-8x

<FDH = 136-8x+112

<FDH = 248-8x

<FDH = 248-8(7)

<FDH = 248-56

<FDH = 192°

For <FDE;

<FDE = <FDG + <GDE

<FDE = 136-8x+8x-1

<FDE = 135°

1.38 is the mean of the amount of rainfall over the course of the week

Answer:

1.4 inches (1 decimal place)

Step-by-step explanation:

To calculate the mean you get the sum of all the terms required and divide by the number of terms you summed up.

All of the terms in the table sum up to 29/3. 29/3 divided by 7 (number of days in a week) = 1.3809..., which you can round to 1.4 inches
