NEED HELP ASAP!! Everyone has different answers, I need the right one, perimeter?

Mr. Fernandez uses 7 boards that are 4 feet long and 6 inches wide to make on bookshelf. If he buys lumber in lengths of 8 feet

True [87]

Bookshelf =7boards each
Lumber=4 boards each
He wants to make 5 bookshelves total
5x7=35
So he needs 35 boards
And each lumber makes 4 boards
So what number times 4 is equal to or more than 35?

9times 4 is 36

So he needs 9 pieces of lumber to make 5 bookshelves.

Good luck with your work! Brainliest would be appreciated :)

What number is 8% of 1,500?

Dima020 [189]

Answer:

120

Step-by-step explanation:

Solution for What is 8 percent of 1500:

8 percent *1500 =

(8:100)*1500 =

(8*1500):100 =

12000:100 = 120

Now we have: 8 percent of 1500 = 120

Question: What is 8 percent of 1500?

Percentage solution with steps:

Step 1: Our output value is 1500.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 1500 = 100%

Step 4: Similarly, x = 8%

Step 5: This results in a pair of simple equations:

1500 = 100% (1).

x = 8% (2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

x 8%

Step 7: Again, the reciprocal of both sides gives

1500 100

x = 120

Therefore, 8% of 1500 is 120

Hope this helps you!!!

Two standardized tests, a and b, use very different scales of scores. the formula upper a equals 40 times upper b plus 50a=40×

Romashka [77]

Answer:

(a) The mean score of test A is 1210.

(b) The mean score of test A is 1210.

(c) The standard deviation of test A is 80.

(d) The value of Q₃ for test A is 1170.

(e) The value of median for test A is 1090.

(f) The value of IQR for test A is 290.

Step-by-step explanation:

The relation between two standardized tests <em>A</em> and <em>B</em> is:

$50A=40B+50$

The equation above approximates the relationship between scores on the two tests.

The summary statistics for test B are as follows:

Lowest Score = 21

Mean score = 29

Standard deviation = 2

Q₃ = 28

Median = 26

IQR = 6

(a)

Compute the lowest score on test A as follows:

$A=40B+50\\=(40\times21)+50\\=890$

Thus, the lowest score on test A is 890.

(b)

Compute the mean score of test A as follows:

<h2> $A=40B+50\\=(40\times29)+50\\=1210$ </h2>

Thus, the mean score of test A is 1210.

(c)

Compute the mean score standard deviation of test A as follows:

<h2> $A=40B+50\\=(40\times2)\\=80$ </h2>

Thus, the standard deviation of test A is 80.

(d)

Compute the value of Q₃ for test A as follows:

$A=40B+50\\=(40\times28)+50\\=1170$

Thus, the value of Q₃ for test A is 1170.

(e)

Compute the value of median for test A as follows:

$A=40B+50\\=(40\times26)+50\\=1090$

Thus, the value of median for test A is 1090.

(f)

Compute the value of IQR for test A as follows:

$A=40B+50\\=(40\times6)+50\\=290$

Thus, the value of IQR for test A is 290.
