Find the volume of a rectangular prism with a length of 5 cm, a width of 5 cm and a

Using each of the digits 0-6 only ones, make two equivalent ready ratios parentheses also known as a proportion brother sees one

nadya68 [22]

Answer:

1. 4/13 = 20/65

2. 4/20 = 13/65

3. 5/10 = 23/46

4. 5/10 = 32/64

5. 5/23 = 10/46

6. 5/32 = 10/64

Step-by-step explanation:

We can make the following six equivalent ratios using the digits from 0 to 6 only once:

1. 4/13 = 20/65 (We multiply 4 and 13 by 5 to get the second equivalent ratio)

2. 4/20 = 13/65 (We divide the first ratio by 4 and the second by 13 and we get 1/5 on both ratios)

3. 5/10 = 23/46 (We divide the first ratio by 5 and the second by 23 and we get 1/2 on both ratios)

4. 5/10 = 32/64 (We divide the first ratio by 5 and the second by 32 and we get 1/2 on both ratios)

5. 5/23 = 10/46 (We multiply 5 and 23 by 2 to get the second equivalent ratio)

6. 5/32 = 10/64 (We multiply 5 and 32 by 2 to get the second equivalent ratio)

Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of 51.1 d

Inga [223]

Answer:

$Mean = 53.25$

Step-by-step explanation:

Given

Low Temperature : 40−44 || 45−49 || 50−54 || 55−59 || 60−64

Frequency: --------------- 3 -----------6----------- 1-----------3--- -----7

Required

Determine the mean

The first step is to determine the midpoints of the given temperatures

40 - 44:

$Midpoint = \frac{40+44}{2}$

$Midpoint = \frac{84}{2}$

$Midpoint = 42$

45 - 49

$Midpoint = \frac{45+49}{2}$

$Midpoint = \frac{94}{2}$

$Midpoint = 47$

50 - 54:

$Midpoint = \frac{50+54}{2}$

$Midpoint = \frac{104}{2}$

$Midpoint = 52$

55- 59

$Midpoint = \frac{55+59}{2}$

$Midpoint = \frac{114}{2}$

$Midpoint = 57$

60 - 64:

$Midpoint = \frac{60+64}{2}$

$Midpoint = \frac{124}{2}$

$Midpoint = 62$

So, the new frequency table is as thus:

Low Temperature : 42 || 47 || 52 || 57 || 62

Frequency: ----------- 3 --||- -6-||- 1-||- --3- ||--7

Next, is to calculate mean by

$Mean = \frac{\sum fx}{\sum x}$

$Mean = \frac{42 * 3 + 47 * 6 + 52 * 1 + 57 * 3 + 62 * 7}{3+6+1+3+7}$

$Mean = \frac{1065}{20}$

$Mean = 53.25$

The computed mean is greater than the actual mean

The ratio of the measures of the sides of a triangle is 7:9:12, and it's perimeter is 84 inches. Find the measures of each side

Ede4ka [16]

Answer:

Step-by-step explanation:

The lengths of the sides are 7x, 9x, and 12x.

7x + 9x + 12x = 84

28x = 84

x = 3 in

Sides: 21 in, 27 in, 36 in

Darren is on a super efficient diet. He started with 210 pounds 2 months ago and he now weighs 150 pounds . Find his percent of

ikadub [295]

Answer:

29%

Step-by-step explanation:

210-150/210 = 60/210 or 6/21

Now we have to find the percent out of 100 so we have to find out 100/21 to see what we have to multiply by to get to 100 so we can do the same with the 2 (numerator) so 1000/21= 4 16/21

then we have to multiply the 6 by 4 16/21 which is about 29%
