Answer:

the answer would be 750 dollars.

Step-by-step explanation:

If he needs $1,000 in total and already has $250, you can do 1,000 - 250 to get 750. A simpler way to.do that could be to take 1,000 - 200 to get 800, and then subtract another 50.

Answer:

C)

B)

C)

Step-by-step explanation:

recall the surface area formula of cylinder

[tex] \displaystyle A _{S} = 2\pi r(h + r)[/tex]

given that,h=5 and r=0.7

substitute:

[tex] \displaystyle A _{S} = 2\pi (0.7)(5 + 0.7)[/tex]

simplify parentheses:

[tex] \displaystyle A _{S} = 2\pi (0.7)(5 .7)[/tex]

simplify multiplication:

[tex] \displaystyle A _{S} =25.0572 sqm[/tex]

hence, our answer is C

remember the surface area formula of cone

[tex] \displaystyle A _{S} = \pi r(r + s)[/tex]

given that,r=7 and s=10

substitute:

[tex] \displaystyle A _{S} = \pi (7)(7+ 10)[/tex]

simplify parentheses:

[tex] \displaystyle A _{S} = \pi (7)(17)[/tex]

simplify multiplication:

[tex] \displaystyle A _{S} =373.66sqcm[/tex]

hence, our answer is B

now for the question-3 we need a little bit understanding

remember the surface area formula of cube

[tex] \displaystyle A _{S} =6 {a}^{2} [/tex]

we are given that,[tex]A_S=600[/tex] Thus

substitute:

[tex] \displaystyle 6 {a}^{2} = 600[/tex]

divide both sides by 6:

[tex] \displaystyle {a}^{2} = 100[/tex]

square root both sides:

[tex] \displaystyle {a}^{} = 10[/tex]

hence, the measurement of each

edge is 10 cm therefore our answer is C)

Answer:

The initial velocity of the particle is

v' = -6 - 6.2 = -18 ft/s

at t = 5s, the velocity is v = -18 + 6.5 = 12 ft/s

the position is

[tex]x = - 32 - 18 \times 5 + \frac{1}{2} \times 6 \times 5 {}^{2} = - 47 \: ft[/tex]

the total distance traveled is

[tex]s = | \frac{12 {}^{2} - 18 {}^{2} }{2 \times 6} | = 15 \: ft[/tex]

Equation to solve for "x": 90 + x + x + 18 = 180

x = 36

Step-by-step explanation:

90 + x + x + 18 = 180

90 + 18 + 2x = 180

108 + 2x = 180

(108 - 108) + 2x = 180 - 108

2x = 72

2x/2 = 72/2

x = 36

90 + 36 + 36 + 18 = 180

108 + 72 = 180

180 = 180

Answer:

340

Step-by-step explanation:

$730 - $50 = $680

$680 / 2 = 340

they both have an equal of 340 and then mike adds in 50 more so:

340 + 340 = 680 + mike's $50 = $730.

Answer:

The units for the area are in square inches or in^2. The approximate value shown above is when using pi = 3.14

=============================================================

Explanation:

Use the pythagorean theorem to find the length of the hypotenuse

a^2 + b^2 = c^2

20^2 + 21^2 = c^2

400 + 441 = c^2

c^2 = 841

c = sqrt(841)

c = 29

The hypotenuse is 29 inches long. This is the diameter of the circle. Half of that is the radius at r = d/2 = 29/2 = 14.5 inches.

The area of the circle is...

A = pi*r^2

A = pi*(14.5)^2

A = pi*210.25

A = 210.25pi

Which is exact in terms of pi

We'll subtract off the triangular region as this isn't shaded in. The area of the triangle is base*height/2 = 20*21/2 = 420/2 = 210 square inches.

So the shaded region is therefore 210.25pi - 210 square inches

This approximates to 210.25*3.14 - 210 = 450.185 when using the approximation pi = 3.14; use more decimal digits of pi to get a more accurate value.

Answer:

10 1/8

Just look it up or something, that's what i did

The area of the given rectangle is 10 1/8 units².

The region is the space taken up by a flat, two-dimensional surface. Its unit of measurement is the square. A three-dimensional object's surface area is the area occupied by its exterior surface. It is also measured in square units.The total surface area is the area encompassing the base(s) and the curving part. It is the whole area that the surface of the object takes up. A shape with a curved base and surface has a total area equal to the sum of the two areas.

As per the given data:

Measurement of the rectangle is given by

2 1/4 units by 4 1/2 units

= 2 1/4 × 4 1/2 units²

To find the area of a rectangle:

Area = length × width

From the given data

length = 4 1/2 units

width = 2 1/4 units

Area = 2 1/4 × 4 1/2 units²

= 9/4 × 9/2 units²

= 81/8 units²

= 10 1/8 units²

Hence, The area of the given rectangle is 10 1/8 units².

they are Vertically Opposite Angles..

Answer:

x = 1.50p - 1,800

Step-by-step explanation:

The equation that depicts their situation is -

1.50[tex]x[/tex] - 1800 = 0

We have a paper company sells paper for $1.50 per package with an overhead cost of $1800.

We have to write an equation which depicts their situation.

Overhead cost to the company are the expenses other than the expenses during the generation of any product or service by that company. These expenses are somewhere needed and a certain amount of money is spent on them independent of the fact how much profit your product or service is generating. Concluding, we can say -

Overhead cost = Unwanted expense to the company

According to question -

Let's assume that the company sells [tex]x[/tex] pieces of paper for $1.50.

The overhead expenses = $ 1800

Hence, the equation that depicts their situation is -

1.50[tex]x[/tex] - 1800 = 0
