How is volume measured? i need a formula using cubes or unit cubes. PLEASE HELP!

gulaghasi [49]

Answer:

The volume of solids is measured in cubic measurements.

Step-by-step explanation:

Examples:

Volume of a cube: V = a^3

Volume of a sphere: 4/3 x pi x r^3

Volume of a triangle: 1/2 x b x h x l

For instance, a sphere with the radius of 5 feet:

4/3 x pi x 5^3 = V

V = 523.6 cubic feet

You and a friend ordered fajitas for two, and agreed to split the bill. The bill came to $19.06. You decided to give a 15 % tip.

just olya [345]

$2.86 if you’re tipping off of $19.06 but if you’re tipping off half of that so the split bill which is $9.53 then your tip is $1.43

klemol [59]

Answer:

s =2

Step-by-step explanation:

you need to multiply to find the answer

6 x 2=12

Then you need to replace the s with 2 and see if it fits correctly in this case it does

6x2 -4 =8

12-4=8

Find the equation for the line of best fit using the two points that are close to the line of best fit (2,70) and (4.5, 90)

kari74 [83]

Given:

Two points that are close to the line of best fit are (2,70) and (4.5, 90).

To find:

Th equation of best fit line using the given two points.

Solution:

We know that, if a line passes through the two points, then the equation of line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

Two points (2,70) and (4.5, 90) are close to the best fit line.

Consider the two points (2,70) and (4.5, 90). So, the equation of line is

$y-70=\dfrac{90-70}{4.5-2}(x-2)$

$y-70=\dfrac{20}{2.5}(x-2)$

$y-70=8(x-2)$

$y-70=8x-16$

Adding 70 on both sides, we get

$y=8x-16+70$

$y=8x+54$

Therefore, the equation of best fit line is $y=8x+54$ .

For the following trapezoid, h = 5 ft, b = 7.9 ft, and B = 14.6 ft. What is the area?

Bond [772]

Answer:

The area of the trapezoid is 56.25² feet.

Step-by-step explanation:

The formula for the area of a trapezoid is $A=\frac{b+B}{2} h$

A = area (of the trapezoid)
b = base of the trapezoid
B = (other) base of the trapezoid
h = height of the trapezoid

*Note: Trapezoids have 2 bases that are parallel to one another, but are not always the same length.

Using the information given to us, we can simply plug in numbers into the equation. By doing so, we'd get $A=\frac{7.9+14.6}{2} 5$ . By plugging this into a calculator, you'd get $A=56.25$ .
