750 sq. Ft / 2 gallons = 375 sq ft per gallon

Divide total square feet by square feet per gallons:

3375 / 375 = 9 gallons total paint required.

Now multiply total gallons needed by price per gallon:

9 gallons x 7.50 per gallon = 67.50

Total cost = $67.50

Answer:

v = 16

Step-by-step explanation:

I am assuming you would like to find the value of v?

-3 = v/4 - 7

we want to get v on its own so that v = ... this means we must 'move' the other values onto the opposing side of the '=' (equals)

first, add 7 to both sides to 'remove' the 7 from 'v' side of the equation

so this means  

-3 + 7 = v/4 - 7 +7

furtherly simplify so that

4 = v/4

v/4 can also be written as v ÷ 4 therefore to 'undo' it we must perform the inverse sign, i.e. '*' multiply 4 to both sides

therefore

4*4 = v ÷ 4 *4

thus

16 = v

v= 16

Answer:

20 ,22 ,24 ,26

Step-by-step explanation:

Consecutive even integers are numbers that are even and are 2 units apart.

If x is the smallest even integer then the 4 consecutive numbers are:

x, x+2, x+4, x+6

The greatest of four consecutive even integers ( x+6) is 14 less (-14) than twice the smallest integer (2x).

x+6 = 2*x -14, add 14 and subtract x from both sides

14+6 = 2x -x , combine like terms

  20 = x

20, 22, 24, 26 are the integers

The difference between a normal integer 1, 2, 3, 4, 5... and an even integer 2, 4, 6, 8, 10, 12, ... is that the normal integers are consecutive when one unit apart, and even integers are consecutive when they are two units apart.

The normal integers have odd and even numbers, while the even consecutive integers are only even numbers.

In a circle with center R, the length of the arc QS is 10.03 units.

A circle is a two-dimensional geometric shape that represents a perfectly round and symmetrical curve. It is a closed curve consisting of all the points in a plane that are equidistant from a fixed center point.

In a circle, the distance from the center to any point on the curve is constant and called the radius. The longest distance across the circle, passing through the center, is known as the diameter. The diameter is twice the length of the radius.

Given that

∠QRS, [tex]\theta[/tex] = 34°

              [tex]=34\times\frac{\Pi}{180} \\= 34\times\frac{3.14}{180} \\= 0.59\ Radian[/tex]

QR, r = 17 units

Length of arc QS = r[tex]\theta[/tex]

                            = 0.59 × 17

                            = 10.03 units.

Thus, the length of arc QS is 10.03 units.

Answer: $2.49

Step-by-step explanation:

6%→0.06Now, we need to multiply the pre-tax cost of this item by this value in order to calculate the sales tax cost.

{Sales tax}=0.06\times\$2.35

Sales tax}=\$0.141

Round to two decimal places since our total is in dollars and cents.

{Sales tax}=\$0.14

Last, add this value to the pre-tax value of the item to find the total cost.

{Total cost}=\$2.35+\$0.14

{Total cost}=\$2.49

Answer:

Step-by-step explanation:

First you have to find out what the sales tax is. You make 6% into 6/100 and  ?/159. You then cross multiply 6 times 159= 954 and you then divide 954 by 100 which gives you 9.54 or 10. Then you subtract 159 by 9.54 which gives you 149. The price limit is 149.

8 and 10 can be divided by 2

Answer: The answer is 4/5

Step-by-step explanation:

Step 1: Write down the decimal divided by 1, like this: 0.800/1

Step 2: Multiply both top and bottom by 1000 (it's 1000 bcuz there're 3 decimal places, if there're 2 decimal places you'll multiply the top and bottom with 100)

                     (0.800/1) x (1000/1000)= 800/1000

Step 3: Simplified it. Notice that both 800 and 1000 can be divided by 200

                       800/200= 4

                       1000/200= 5

=> 4/5

= 3b^2 + 4ab - 2a^2 - 4a^2 + 3ab - 2b^2

= 3b^2 - 2b^2 - 2a^2 - 4a^2 + 4ab + 3ab

You can use the specified conversion scale to convert the weight given to kilograms.

The mass of given bulb in kilogram is 0.000245 kilogram.

If a quantity is given in one unit and its unit of measurement has to be changed to other unit, then you will have to get to know how is first unit related to other. Based on that, you can convert the unit of measurement to desired unit of measurement.

Since 1000 mg = 1 gram, thus,

Dividing by 1000 on both sides, we get:

[tex]\dfrac{1000}{1000} \: \rm mg = \dfrac{1}{1000} \: \rm g\\ \\ 1 \: mg = 0.001 \: g\\ \\ \text{Multiplying 245 on both sides}\\\\ 245 \times 1 \: mg = 245 \times 0.001 \: g = 0.245 \: g\\ 245 \: mg = 0.245 \: g[/tex]

Now since 1000g = 1 kg, thus,

Dividing by 1000 on both the sides,

[tex]\dfrac{1000}{1000} \: \rm g = \dfrac{1}{1000} \: \rm kg\\\\1 \: g = 0.001 \: kg\\\\\text{Multiplying 0.245 on both sides}\\\\0.245 \times 1 \: g = 0.245 \times 0.001 \: kg = 0.000245 \: kg\\0.245 \: g = 0.000245 \: kg[/tex][tex]\dfrac{1000}{1000} \: \rm g = \dfrac{1}{1000} \: \rm kg\\\\1 \: g = 0.001 \: kg\\\\\text{Multiplying 0.245 on both sides}\\\\0.245 \times 1 \: g = 0.245 \times 0.001 \: kg = 0.000245 \: kg\\0.245 \: g = 0.000245 \: kg[/tex]

Answer:

b = (13 root under 3)/2

Step-by-step explanation:

taking 60 as reference angle,

cos60 = b/h

1/2 = x/15

or, 15 = 2x

so, x = 7.5

Now

h² = p² + b²

15² = x²+z²

225 = (7.5)²+z²

or, 225-56.25 = z²

or, z² = 168.25

so, z = 12.97

so, z = 13 approximately

now

sin60 = p/h

or, sin60 = y/x

or, sin60 = y/7.5

or, sin60.7.5 = y

so, y = 6.5

now

taking 30 as reference angle,

cos30 = b/h

or, cos30 = b/z

or, cos30 = b/13

or, cos30.13 = b

so, b = 11.3 approximately
