What is the product of 7/16, 4/3, and 1/2?

What is the product of 7/16, 4/3, and 1/2

7/16 * 4/3 * 1/2

= (7/16 * 4/3) * 1/2 (doesn't the group order, result remains the same)

= 28/48 * 1/2

= 28/96

= 7/24

7/16 * 4/3 * 1/2

= (7/16 * 4/3) * 1/2 (doesn't the group order, result remains the same)

= 28/48 * 1/2

= 28/96

= 7/24

If f(x)=-2x+2 then find f(1/2)

Answer:

F is 0

Step-by-step explanation:

If you divide X on both sides to get X on one side, it will end with F = -2 + 2, which is 0

Write the number 392 as hu

ndred. tens and ones

Well 392 = 300 (Hundred), 90 (Tens), 2 (Ones)

300=Hundreds

90=Tens

02= Ones

90=Tens

02= Ones

How do you write 5,392,029,004 in expanded form

5,000,000,000 + 300,000,000 + 90,000,000 + 2,000,000 + 20,000 + 9,000 + 4

Elizabeth brought a box of donuts to share. There are two-dozen (24) donuts in the box, all identical in size, shape, and color. 6 are jelly-filled, 10 are lemon-filled, and 8 are custard-filled. You randomly select one donut, eat it, and select another donut. Find the probability of selecting two custard-filled donuts in a row. Write your answer as a fraction in simplest form.

The probability of selecting two custard-filled donuts is: 7/69

The distribution of donuts is given as:

Eating a selected donut is an illustration of a selection without replacement.

So, the probability of selecting two custard-filled donuts is:

Substitute known values

Simplify

Further, simplify

Calculate the product

Hence, the probability is 7/69

The probability of the first selection being custard-filled is 8/24. If a custard-filled donut was selected first, there are 7 custard-filled donuts remaining among a total of 23 donuts. Therefore the probability of the second selection being a custard- filled donut is 7/23. The required probability is therefore:

(8/24) x (7/23) = 7/69

The answer is 7/69

(8/24) x (7/23) = 7/69

The answer is 7/69

Two groups of workers are painting a bridge in the bay. The first group is responsible for painting the north side of the bridge, and the second group is responsible for painting the south side of the bridge. The first group has already painted 2 kilometers of the bridge and is painting 2 additional kilometers per day. The second group has already painted 5 kilometers of the bridge and is painting 1 additional kilometer per day. When the two groups have painted the same amount of the bridge, how much of the bridge will they each have painted?

Answer:

They will each have painted 8 km. This goal will be met on Day 4.

Step-by-step explanation:

Group A | Group B

Start: 2 | Start: 5 Day 1

2 + 2 = 4 | 5 + 1 = 6 Day 2

4 + 2 = 6 | 6 + 1 = 7 Day 3

6 + 2 = 8 | 7 + 1 = 8 Day 4

The length of a rectangle is 3 inches more than its width. If the perimeter is 42 inches, find the dimensions of the rectangle.

The problem uses the perimeter formula. P = 2w + 2l where w is the width, and l is the length.

We know the length (l) is 3 inches longer than it's width (or l = w+3). Substitute w +3 into Perimeter equation

P = 2w + 2(w+3). That simplifies to P = 4w + 6.

Since P + 42, we have 42 = 4w +6. With some simple algebra we find that w = 9 and l = 12.

Hope this helps!

Width is 12 and length is 9

5 apple pies ,you need about 2 pounds of apples. How many pounds of apples do you need to make 20 apple pies

8; 20/5=4, 4*2=8 so therefore it's 8 pounds

8 lbs; 20/5=4x2=8

Or 10 pies= 4lbs then 4x2 because 2lbs per 5 pies which = 8

Or 10 pies= 4lbs then 4x2 because 2lbs per 5 pies which = 8
