Jorge bought a new computer for $399 and extra computer memory for $42. Give the percentage of the total amount that Jorge spent was the cost of the computer? Round to the nearest tenth of a percent, if necessary. A. 9.5% B. 10.5% C. 90.5% D. 92.6%

Answers

Answer 1

Answer: The answer is letter D which is 90.5%. To come with the answer you need to add the cost of new computer which is $399 and the computer memory which is $42 with the total amount of $441. Then you $399 by $441 and multiple by 100%.

Solution:

= $399 + $42

= $441

=$399/$441 x 100%

=.9048 x 100%

= 90.48% or 90.50%

Sam has 12 black and white photos and 18 color photos.he wants to put the photos in equal rows so each row has either black and white photos only or color photos only. in how many rows can Sam arrange the photos

Answers

The question is asking us to determine the number of rows in which Sam can arrange his 12 black and white and 18 color photos. Sam wants to put them in the equal rows so that each row has either black and white photos only or color photos only. We have to find the GCF ( the Greatest Common Factor ) of 18 and 12. GCF ( 18, 12 ) = 6. So there should be 6 photos in each row if they have to be equal ( the equal number of photos in every row ). 18 = 6 * 3 and 12 = 6 * 2. Therefore the number of the rows is : 3 + 2 = 5. Answer: Sam can arrange his photos in 5 rows.

Answer:

Step-by-step explanation:

First you have to find the GCF (greatest common factor) and the GCF is 6

Then you have to multiply 3×6 = 18, 2×6 = 12

Next add 3 + 2 = 5 because I added the first digits of the multiplying thinge

How many 2-inch segments are there in 12 ft.?
a. 6
b. 24
c. 72
d. 10

Answers

When we convert 12 feet to inches and then divide by the length of each segment (2 inches), we find that there are 72 two-inch segments in 12 feet.

To calculate how many 2-inch segments are there in 12 feet, we need to convert both measurements to the same unit before performing the division.

Step 1: Convert 12 feet to inches.

Since 1 foot is equal to 12 inches, to convert 12 feet to inches, we multiply by 12:

12 feet * 12 inches/foot = 144 inches

Step 2: Divide the total number of inches by the length of each segment (2 inches).

144 inches ÷ 2 inches/segment = 72 segments

Therefore, there are 72 two-inch segments in 12 feet.

In summary, when we convert 12 feet to inches and then divide by the length of each segment (2 inches), we find that there are 72 two-inch segments in 12 feet. This calculation involves converting units to ensure they are in the same measurement scale before performing the division.

Suppose that we have a right triangle $ABC$ with the right angle at $B$ such that $AC = \sqrt{61}$ and $AB = 5.$ A circle is drawn with its center on $AB$ such that the circle is tangent to $AC$ and $BC.$ If $P$ is the point where the circle and side $AC$ meet, then what is $CP$?

Answers

Answer:

CP = 6

Step-by-step explanation:

The length of segment BC is given by the Pythagorean theorem:

AC² = AB² +BC²

(√61)² = 5² + BC² . . . . . fill in the given numbers

61 -25 = BC² = 36 . . . . .subtract 25

BC = 6 . . . . . . . . . . . . . . take the square root

Since the center of the circle is on AB and is tangent to BC, it must pass through point B. That is, segment BC of length 6 is one of the tangent lines from point C. The other one, to point P, must be the same length, so ...

CP = 6
