What is the volume of a cone with a diameter of 8 in and a height of 5 in?

Answer:

He multiplyed 3x8 and 5x8 when it should be 3x8 and 5x1 because you but 1 under the 8 to make it into a  fraction.

Answer:

C. supplementary

Step-by-step explanation:

Answer:

150120.83 ; 40 ; 1800

Step-by-step explanation:

Amount of share per person = x

Number of persons = y

x = k/y

k = constant of proportionality

k = xy

257,350 * 7 = 1801450

k = 1801450

If there are 12 persons ; y = 12

x = k/y

x = 1801450 / 12

x = 150120.83

2.) weight on Mars = m

Weight in earth = e

m α e

m = ke

48 = 120k

k = 48 / 120

k = 0.4

m = 0.4 * 100

m = 40

3.)

I α pt

I = kpt

600 = k * 10000 * 2

600 = 20000k

k = 600/20000

k = 0.03

I = 0.03 * 15000 * 4

I = 1800

Answer:

The answer is x=6, y=3

Step-by-step explanation:

Multiply each equation by the value that makes the coefficients of y opposite(−1)⋅(4x−7y)=(−1)(3)x−7y=−15

Simplify.

−4x+7y=−3x−7y=−15

Add the two equations together to eliminate y from the system.−4x+7y=−3+x−7y=−15−3x=−18

Divide each term by −3 and simplify.

x = 6

Substitute the value found for x into one of the original equations, then solve for y.

y = 3

The solution to the independent system of equations can be represented as a point.(6,3)

The result can be shown in multiple forms.

Point Form: (6,3)

Equation Form: x=6, y=3

Answer:

Step-by-step explanation:

0.40beta%2Bbeta=180-5

1.40beta=175

beta=175%2F1.40

highlight%28beta=125%29�

then alpha%2B125=180 =>alpha=180-125 =>highlight%28alpha=55%29

The required values of angles are 125 and 55.

When two straight lines come together at a point, they produce an angle, which is represented by the symbol.

Given that,

Two angles are supplementary to each other.

Let angles are α and β.

According to given condition,

α + β = 180      (1)

Also, the measure of one angle α is 5 greater than 40% of the other.

α = 0.4 β + 5      (2)

Substitute the value of α in equation (1),

0.4 β + 5 + β = 180

1.4 β = 175

β = 175 / 1.4 = 125

The value of α =0.4 x 125 + 5 = 50 + 5 = 55

The value of angle α and β are 125 and 55.

i believe the answer is A.

Step-by-step explanation: Because the angle PQS is not a 90 degree angle it should equal 180 degrees, it is now lowered down to the answers A. and B. Answer B. has 2x and answer A. has just x. if it were to be 2x then the x would  have to represent 30 degrees but the point plotted x does not equal 30 degrees therefore leaving the last answer as A. x-60=180

Answer:

y = (2/3)x - 2

Step-by-step explanation:

The equation of this line is y = (2/3)x - 2, where m is the given slope and -2 is the given y-intercept.  We need only plug in the given values for m and b.

Answer:

[tex]y = \frac{2}{3} x -2[/tex]

Step-by-step explanation:

This is the slope-intercept form. The slope-intercept form is written as y = mx + b where m is the slope and b is the y-intercept. The y and x stay as they are.

I hope this was what you were looking for.

Given:

[tex]\cos \angle A=\dfrac{342}{1000}[/tex]

To find:

The measure of angle A to the nearest degree.

Solution:

We have,

[tex]\cos \angle A=\dfrac{342}{1000}[/tex]

It can be written as

[tex]\angle A=\cos ^{-1}\dfrac{342}{1000}[/tex]

[tex]\angle A=70.00123^\circ[/tex]

[tex]\angle A=70^\circ[/tex]

Therefore, the measure of angle A to the nearest degree is 70 degrees.

Answer:

Step-by-step explanation:

3 ( x - 3 ) = 5x - 4 + 3 ( 7 - x )

3x-9 = 5x-4 + 21 - 3x

collect like terms

3x-9 = 2x +17

move the terms

3x-2x = 17+9

x=26

Answer:

26

Step-by-step explanation:

3 (x-3) = 5x - 4 + 3 (7-x)

3x - 9 = 5x - 4 + 21 - 3x

3x - 9 = 5x - 3x + 17

3x - 9 = 2x + 17

3x - 2x = 17 + 9

x = 26

Answer:

If we add up all the angles of any triangle, we should get 180 degrees. Therefore, Angle C = 90 (angle A) - 45 (angle B) = 45 degrees. Since there was a ray drawn from A through C the exterior angle of angle C is angle 1.

Step-by-step explanation:

a "one angle" A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. ... Because a full rotation equals 2π radians, one degree is equivalent to π180 radians.

Answer:

she can fill 6 if them

Step-by-step explanation:

2/3 ÷ 4 = 1/6

Answer:

Step-by-step explanation:

You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.

You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.

That leaves you with one unknown angle. ? = 180°-40°-55° = 85°
