What is an equivalent fraction for 4 21/4

Answers

Answer 1

Answer: The answer is 5 1/4, because 4 goes into 21, 5 times, adding 1 whole number making it 5. also, 21-20=1 (just giving all information), and, the denominator always stays the same, but not needed for multiplying and dividing (cuz dividing is almost the same as multiplying). So the answer to ur question is 5 1/4. Hope it helps! ;)

Answer 2

Answer: 4 and 21/4
9 and 1/4
Happy to Help!

To find the area of the shaded region, we can find the area of the rectangle, and subtract the area of the circle (the non shaded part of the rectangle).

Area of Rectangle:
A= 21in x 16in = 336in^2

Area of Circle:
A = pi * r^2
A = 3.14 * (8in)^2
A = 3.14 * 64in^2
A = 201in^2

Subtracting the non shaded region from the area of the rectangle:
336in^2 - 201in^2 = 135in^2

Therefore, the answer is 1. 135in^2

The first thing you would do is find the area of the rectangle.

To find the area of a rectangle you would use length x width

So it already gives you the length which is 21, now you can find the width by looking inside at the radius of the circle (8). That would be half of the width. Which means we would multiply 8 by 2.

8 x 2 = 16 so the width is 16. Now the only thing left to do is to multiply the width times the height.

16 x 21 = 336

The area of the rectangle is 336.

Next we need to find the area of the circle.

To find the area of a circle you would do Pi x r^2

The radius is 8. 8^2 = 64 then multiply that by Pi (3.14)

64 x 3.14 = 200.96

We have the area of the rectangle and the circle. The only thing left is to subtract the area of the circle from the area of the rectangle.

336 - 200.96 = 135.04

The answer would be 1. 135 in^2

you have a 4x6 photo of you and your friend. You order a 5x7 print of the photo. Is the new photo similar to the original?

Answers

No because 4 times 6 =24 and 5 times 7 =35

Math wise no. 5×7 is a bigger form than 4×6, think of it like this, 4 squares up, and 6 squares side, same with the 5x7, its a bigger area and perimeter

The figure is made up of a cylinder and a sphere which has been cut in half. The radius of each half sphere is 5 mm. What is the volume of the composite figure? Use 3.14 for Pi. Round to the nearest hundredth. A cylinder and 2 half spheres. All have a radius of 5 millimeters. The cylinder has a height of 10 millimeters. Recall the formulas V = B h and V = four-thirds pi r cubed 376.80 cubic millimeters 847.80 cubic millimeters 1,177.50 cubic millimeters 1,308.33 cubic millimeters

Answers

Answer:

$1308.33 {mm}^(3)$

Step-by-step explanation:

The volume of the composite shape is given by:

Volume of cylinder +volume of two spheres.

The volume of cylinder

$= \pi \: {r}^(2) h$

We substitute r=5mm and h=10mm

The volume cylinder becomes

$= \pi \: * {5}^(2) * 10 \n = 250\pi$

$= 250 * 3.14 \n = 785 {mm}^(3)$

The volume of the two hemispheres

$= (4)/(3) \pi {r}^(3)$

We substitute the radius to get:

$= (4)/(3) * \pi * {5}^(3) \n = 523.33 {mm}^(3)$

We add the two volumes to get:

$= 785 + 523.33 = 1308.33 {mm}^(3)$

Is the GCF (Greatest Common Factor) of a pair of numbers ever greater than both numbers? Explain with an example.

Answers

The GCF can be the smaller one of the two numbers,
or else it can be a number smaller than either of them.
It can never be more than the smaller of the two numbers.

-- The GCF of 10 and 100 is 10 .

-- The GCF of 9 and 102 is 3 .

-- The GCF of 10 and any number more than 10
an never be bigger than 10 .

Basically, what I would say is that the Greatest Common Factor is no larger than smallest. Keep in mind that Greatest means biggest, but don't let it trick you.
