Answer:

The equation is 3x + 24 = 6x

Step-by-step explanation:

Let

Zach's age = x

If Zach added 8 to his age and multiplied this sum by 3.

Zach = 3(x + 8)

= 3x + 24

James = 6x

Zach's age = James's age

3x + 24 = 6x

Collect like terms

24 = 6x - 3x

24 = 3x

Divide both sides by 3

x = 24/3

= 8

x = 8

Check

Zach = 3(x + 8)

= 3(8+8)

= 3(16)

= 48 years

James = 6x

= 6(8)

= 48 years

The equation is 3x + 24 = 6x

Find the volume of a cone of radius 49cm and height 10cm​
den301095 [7]

Answer:

<h2> 25154.34{cm}^{3}</h2>

Step-by-step explanation:

Given,

Radius ( r ) = 49 cm

Height (h) = 10 cm

Volume of cone=?

Now,

Applying the formula to find the volume of cone:

\pi \:  {r}^{2}  \frac{h}{3}

Plugging the values,

\frac{22}{7}  \times  {49}^{2}  \times  \frac{10}{3}

\frac{22}{7} \times 2401 \times  \frac{10}{3}

Calculate

25153.34  \:  {cm}^{3}

Hope this helps...

Good luck on your assignment..

Which of the following is a true statement
77julia77 [94]

Answer:

11/15 < 4/5

Step-by-step explanation:

1.  5/6 = 10/12, so the first answer is not correct

2. 1/4 = 4/16, so the second answer is not correct

3. 3/4 = 9/12 and 4/6 = 8/12, so the third answer is not correct

4. 4/5 = 12/15 > 11/15, so this answer is correct

Are shape I and shape II similar? If so, give the dilation that proves they are similar. If not, explain why the shapes are not
e-lub [12.9K]

Answer:

The answer is "They are similar".

Step-by-step explanation:

They were comparable in this respect because both aspect ratios of the top triangle are one square more. The top triangle is equal to the base triangles if you remove one square away from the height and width.

Otherwise, we can say that it forms all different. The dilation factor which translates that bottom left point of shape I to form II is 2. But this does not map the other shape I vertices onto form II. There's, therefore, no dilation in form I of maps on form II.
