Answer 1

Answer:

3 inches

Step-by-step explanation:

Volume of a hemisphere = [tex]\frac{2}{3}[/tex]π[tex]r^{3}[/tex]

=> 18π = [tex]\frac{2}{3}[/tex]π[tex]r^{3}[/tex]

=> 18 = [tex]\frac{2}{3}[/tex][tex]r^{3}[/tex]

=> [tex]r^{3}[/tex] = 18 × [tex]\frac{3}{2}[/tex]

=> [tex]r^{3}[/tex] = 27

=> r = [tex]\sqrt[3]{27}[/tex]

=> r = 3 inches

Therefore, the radius of the hemisphere in inches is 3 inches.

Hope it helps :)

Answer:

C)

Step-by-step explanation:

First, multiply the 2 factors that add up to 8.

1/3 x 2. Since this equation does not have one x but 2 (x and y), we will not subtract or divide any sides.

Divide and multiply 2 by 8 and 1/3. Then, we solve for y.  

y = 2/3x - 4

Hope this helps!

Answers

Answer:

The slope of the line is constant. This is because all straight lines have a constant slope. The slope of this line is 1/3. When you use the legs to measure, the horizontal legs of the triangle, they increase in length by 3 units from the previous triangle. The vertical legs of the triangle also increase by 1 with each added triangle. Both of these observations support that the slope of the line is a constant 1/3.

What is the solution to the equation?

2/3a - 1/6 = 1/3​

Answers

Answer:

a = 3/4

Step-by-step explanation:

2/3a - 1/6 = 1/3​

Multiply each side by 6 to clear the fractions

6*(2/3a - 1/6) = 6*1/3​

Distribute

4a - 1 = 2

Add 1 to each side

4a -1+1 = 2+1

4a = 3

Divide each side by 4

4a/4 = 3/4

a = 3/4

Answer:

Step-by-step explanation:

1. π ≈ 3.1415. π + 10 ≈ 13.1415.

2. Find the square root of 20. It is about 4.4721. 4.4721 + 1/2 (or .5) = 4.9721

3. The square root of 100 is 10.

4. Order them.

5. It is most obvious that the answer to [tex]\sqrt{20\\}[/tex] + 1/2 is first. The square root of 100 is ten, so that goes second because pi + 10 is greater than 10. (pi + 10 goes last)

6. [tex]\sqrt{12} + 1/2, \sqrt{100}, \pi + 10[/tex]

The answer is c

I don't understand this
plz answer 3,4 and 5

Answers

Answer:

3. Since it asked us to write question 3 in the from y=mx + c

m is the gradient

c is the intercept on y axis or where the line enters or cuts the y axis. This can be seen from the diagram. The line cuts the y axis at "9". (Check the diagram for this).

Now to find m.

Pick points on the line

Say (1,6) and (2,3)

Gradient = m = y2 - y1/(X2 - X1)

x1 = 1

y1 =6

x2 = 2

y2 = 3

Substituting into that formula

m = 3 - 6/2 - 1

m= -3/1

m= -3.

Since we've gotten what we need

y=mx + c

Y= -3x + 9.

4. 4x + 2y = 12

Rearranging by making y subject to suit the eqn...y=mx + c

you have

m is the gradient and c is the intercept.

2y = -4x + 12

Divide through by 2

y= -2x + 6

y=mx + c

By comparing...

m==gradient = -2

c== Intercept = 6

5). Doing the same thing we did above

-6x + 3y =21

Making y subject

3y = 6x + 21

Divide through by 3

y= 2x + 7

y=mx + c

m==gradient =2

c==Intercept =7.

Hope this helps.

Have a great day!

Answers

Answer:

D

Step-by-step explanation:

First, plot the points they gave you onto a graph (shown in the attached image). The slope is the rise (units up or down from a given point) over the run (units left or right from a given point).

So the slope is 6/4 because to get from the red point to the blue point, you rise 6, and run 4. And from blue to red you rise (remember rise goes up or down) 6 and run 4. 6/4 can be simplified to 3/2 so D is your answer :)

The answer is D.

Answers

Answer:

[tex]6\frac{1}{2}[/tex]

Step-by-step explanation:

When given the following problem:

[tex]7\frac{1}{7}-\frac{9}{14}[/tex]

Convert the first mixed number to an improper fraction. This can be done by multiplying the "number" part of the mixed number by the denominator of the fraction, the number under the fraction bar. Then add the result to the numerator.

[tex]\frac{50}{7}-\frac{9}{14}[/tex]

To perform this operation, one must ensure that both denominators have the same value. Multiply the numerator and denominator for the first fraction by (2), so that the denominators of both fractions is (14),

[tex]\frac{100}{14}-\frac{9}{14}[/tex]

Perform the operation, subtract one numerator from the other, leave the denominators the same,

[tex]\frac{91}{14}[/tex]

Simplify, divide the numerator by (14) (the denominator), write the whole part as the "number" part of the mixed number. Then write the remainder on top of the fraction bar.

[tex]6\frac{7}{14}[/tex]

Reduce, divide the numerator and denominator by a common fraction,

[tex]6\frac{1}{2}[/tex]

Convert the mixed numbers to improper fractions, then find the LCD and combine.
The answer is 6 1/2
