What is the total surface area of the prism?

Answer:

5/6 (decimal form: 0.83)

Step-by-step explanation:

Step-by-step explanation:

Answer:

70cm

Step-by-step explanation:

12 + 22 + 12 + 4 = 50

There are 50 marbles you can choose from and 12 green marbles so the chance of you getting a green marble is:

12/50

= 0.24

24%

Answer:

profit : $28

profit percentage: 14%

Step-by-step explanation:

his profit :    $1.14 times 200kg = $228

228 -200 = 28

28 divided by 200 = 0.14

0.14 times 10 = 14 %

Perimeter = 2 (l + b)

2x² + 4x - 4y = 2 {(2x - 3y) + b}

2x² + 4x - 4y = (4x - 6y) + 2b

2x² + 4x - 4y - (4x - 6y) = 2b

2x² + 4x - 4y - 4x + 6y = 2b

2x² + 2y = 2b

(2x² + 2y)/2 = b

x² + y = b

Breadth = x² + y

First setup the equation for how much element is remaining after each day:

 y = a ( 100% - 3.418%)^t

where y is the amount remainig and t is the number of days

We can clean this up by subtracting the percentages and converting that to a decimal:

  y = a (0.96582)^t

Now for the half-life, we need to figure out how long until there's half of what we started with.  When does "a (0.96582)^t" equal "1/2 of a"

1/2a = a (0.96582)^t

divide by a on both sides and you get

1/2  = (0.96582)^t

take the log of both sides and you get:

log(1/2) = t log(0.96582)

divide both sides by log(0.96582)

 log(1/2) / log(0.96582) = t

Throw that into a calculator and you have

 t ≈ 19.93

Answer:

11

Step-by-step explanation:

y=(3 x 4)-1

y=12-1

y=11

Answer:

y = 11

Step-by-step explanation:

Substitute the value for x.

Answer:

1428- one is in the thousandth place

the number beside is lower than five so drop it and add zero to the end

1000 -is now your answer

Step-by-step explanation:

hope this helps if not then sorry goodluck and bye

The number 1428 to the nearest thousand is 1000.

When you round a number to a certain digit, you have to check the value of the digit before the place you want to round off to.

1. If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

2. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

Here, the question said the nearest thousand, so I had to look at the value in the hundred places which is 4 and less than 5.

Hence round the number down.

So,  1428 to the nearest thousand is 1000.

Answer:

5 8/11, 57/10, 5.724, 5.95

Step-by-step explanation:

Step-by-step explanation:

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

The median is the middle value when a data set is ordered from least to greatest.

If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

so, the mean value is

(10+10+18+18+10+5+12+13)/8 = 96/8 = 12

the median is first not clear when ordering the data set, as we have an even number of elements.

5 10 10 10 12 13 18 18

so, we have to take the mean or average between the 2 middle numbers : 10 and 12.

(10+12)/2 = 22/2 = 11

the median is 11.

Answer:

12 students

Step-by-step explanation:

First, find the percentage of how many students have siblings:

3/10 = 0.3 = 30%

40 * 0.3 = 12

This means that 30% of this class are 12 students. These 12 students have siblings.

Hope this helps!

Answer:

8 years old

Step-by-step explanation:

Set Amy's age as x.

Kevin's age will be 2x, since he is two times as old as Amy.

Father's age will be 5x, since he is five times as old as Amy.

x + 2x + 5x = Sum of the ages = 64

x + 2x + 5x = 64

Combine like terms: 8x = 64.

Divide 8 on both sides: x = 8.

Amy's age = 8.

Hope this helps!

We have 5 ft 9 in = 69 in, so

P(X > 69) = P((X - 64.1)/2.5 > (69 - 64.1)/2.5) = P(Z > 1.96)

where X and Z both represent women's heights, but Z is normally distributed with mean 0 and s.d. 1.

Then consulting a table of z-scores, you'll find that P(Z > 1.96) ≈ 0.025. So approximately 2.5% of women are taker than 5'9''.
