Translate the word phrase into a variable expression.The quotient of a number and 3 is decreased by 1.

Answers

(x)/(3) - 1

quotient is the answer you get when you divide, a number and three is understood as x ÷ 3 , or (x)/(3)

decreaed by one, is understood as the first part of the expression has 1 subracted from it.
let the number be x
the quotient of the number and three : x/3
when it is decreased by 1 : (x/3) - 1

so the answer will be (x/3) - 1

What is the volume of the right prism?A. 50 in3

B. 600 in3

C. 1200 in3

D. 400 in3

Answers

Volume of a right prism = Area of the base * height

the base is the right triangle.
Area of a right  triangle = ab/2
a = 15 inches ; b = 8 inches

Area of a right triangle = (15in * 8in)/2 = 120 in² / 2 = 60 in²

V = B * h
V = 60 in² * 10 in 
V = 600 in³  Choice B.

Is the ordered pair (4, 20) a solution to the equation y = 5x? If yes, is it the only solution?A. Yes, and it is the only ordered pair that fits the equation. B. Yes, but it is not the only solution to the equation. C. No, because the ordered pair does not fit the equation.

Answers

The answer is yes,  it is an answer.  Plug in the values.  The x comes first and y is second in the order pair.  5*4=20
Now,  no,  it is not the only answer.  There are infinitely many solutions.  Any value can be x,  y is just 5 times larger.
So the answer is B,  hope this helps!

Nina's garden is 4 1/5 meters long and 3/10 meter wide. what is the area of nina's garden

Answers

Area of rectangular garden = 21/5*3/10 = 63/50 =1 * \n 13/50 m^(2) = 1.26 m^(2)

Consider Nina' s Garden is rectangular in shape

Length of the garden = 4 * 1/5 = 21/5

Width of the garden = 3/10

Area of the rectangle is given by

Area = Length * Width

So the area of the garden is given by

Area= 21/5*3/10 = 63/50 =1 * \n 13/50 m^(2) = 1.26 m^(2)

For more information please refer to the link

Area= length * width

length = 4 1/5= 21/5 . Multiply the whole number with the denominator. 4*5= 20 . Add 20 with the numerator. 20+1=22

width= 3/10

21/5* 3/10 ( Multiply the denominators together). ( Multiply the numerators together).

21*3 / 5*10

= 63/50 meters^2 or in mixed number:1 13/50 meters^2

Answer : 63/50 meters^2 or in mixed number:1 13/50 meters^2

Maria and Jeff collect data on the number of cars that pass through an intersection every Monday morning for 2 months. They record the findings as 78, 158, 63, 71, 56, 67, 75, and 64. They each use different methods to summarize the typical number of cars that pass through the intersection at the specified time and compare their findings. Jeff says that, on average, 79 cars pass through the intersection each Monday morning. Maria disagrees and says that the mean should not be used and uses the median instead to describe the typical number of cars that passes through the intersection on any given Monday morning.A) What is the median value of the data?
