Yesterday the Bandits scored 56 points in their basketball game. Today they scored 42 points. What is the percent decrease of Th

FromTheMoon [43]

Answer:

x = 25% percent decrease

Step-by-step explanation:

For this problem we will use percentage calculation and make proportion:

Initial value 56 points is worth 100%

Second value 56 - 42 = 14 points of decrease is worth x%

56 : 14 = 100 : x

When we multiply external and internal members we get:

56 · x = 14 · 100 => x = 1400/56 = 25%

x = 25% percent decrease

in 2010, the price of a laser printer was $1599. in 2018, the price of the same type of printer had dropped to $579. find the pe

uysha [10]

Hi there!

nearest percentage=64%

1.Subtract starting value and final value:

$1599-579=1020$

2.Divide it by the starting value:

$1020*1599= 0.6378986866791744840525328330206378986$

3.Multiply the term by 100:

$0.6378986866791744840525328330206378986$ · $100= 63.78986866791744840525328330206378986$

4.Round the term:

$63.78986866791744840525328330206378986=64$

Therefore, the decrease of the total 8 years was 64%.

igor_vitrenko [27]

Answer:

The values of y would be -9 and 15

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$d=13\ units$

S(-2,3) and T(3,y)

substitute the given values in the formula and solve for y

$13=\sqrt{(y-3)^{2}+(3+2)^{2}}$

$13=\sqrt{(y-3)^{2}+25}$

squared both sides

$169=(y-3)^{2}+25$

$(y-3)^{2}=169-25$

$(y-3)^{2}=144$

take square root both sides

$y-3=(+/-)12$

$y=3(+/-)12$

$y=3(+)12=15$

$y=3(-)12=-9$

therefore

The values of y would be -9 and 15

olchik [2.2K]

If we let p and t be the masses of the paper and textbook, respectively, the equations that would best represent the given in this item are:
(1) 20p + 9t = 44.4
(2) (20 + 5)p + (9 + 1)t = 51

The values of p and t from the equation are 0.6 and 3.6, respectively. Thus, each paperback weighs 0.6 pounds and each textbook weighs 3.6 pounds.
