If 75% is 60, what is the full cost?

Answers

If 75% is 60 then:
$0.75x=60$
Solve for x by dividing both sides by 0.75:
$(0.75x)/(0.75)=(60)/(0.75)$
$x=80$

The answer would be 80

Ryker is given the graph of the function y= 1/2x^2 - 4 . He wants to find the zeros of the function but is unable to read them exactly from the graph. Find the zeros give answer to nearest tenth

Answers

Answer:

x= 2.8 and x= -2.8

Step-by-step explanation:

$y=(1)/(2)x^2-4$

To find out the zeros, we replace x y with 0 and solve for x

$0=(1)/(2)x^2-4$

Add 4 on both sides

$4=(1)/(2)x^2$

Multiply by 2 on both sides

8= x^2

Now we take square root on both sides

x= +- $√(8)$

x=2.82843 and x=-2.82843

x= 2.8 and x= -2.8

$y=(1)/(2)x^2-4\n\nzeros\ when\ y=0\n\n(1)/(2)x^2-4=0\n\n(1)/(2)x^2=4\ \ \ \ /\cdot2\n\nx^2=8\n\nx=-\sqrt8\ and\ x=\sqrt8\n\n\underline{\underline{x\approx-2.8\ and\ x\approx2.8}}$

In 1990 retail sales at bookstores were about $7.4 billion. In 1997 retail sales at bookstores were about $11.8 billion. Write a linear model for retail sales s (in billions of dollars) at bookstores from 1990 through 1997. Let T represent the number of year since 1990. Then estimate the retail sales at bookstores in 2012.

Answers

hopefully this helps you and gives you insight in how to solve the problems from now on (:

= $11.8 + (2012-1997)([$11.8-$7.4][1997-1990])

= $11.8 + 5 ($4.4/7)

= $11.8 4/5 + $22/7

= $59/5 + $22/7

= $413/35 + $110/35

= $523/35 or $14 33/35

answer : SALES IN 2012 WOULD BE $14 33/35 BILLION OR $14.9 3/7

Final answer:

A linear model representing retail sales at bookstores from 1990 through 1997 is s(T) = 0.63T + 7.4. The estimated sales at bookstores in 2012 would be approximately $21.46 billion.

Explanation:

To solve this problem, we need to create a linear model. A linear model is a mathematical representation expressed as y = mx + b, where m is the slope, and b is the y-intercept.

To determine the slope (m), we subtract the ending value of retail sales from the starting value and divide by the number of years. So, subtract $7.4 billion (sales in 1990) from $11.8 billion (sales in 1997) and divide by 7 (the number of years from 1990 to 1997): (11.8 - 7.4) / 7 = 0.63. So, m = 0.63.

The y-intercept (b) is the value of y when x = 0. In this model, this corresponds to the sales in 1990, because x is the number of years since 1990, and 'x = 0' therefore corresponds to the year 1990. So, b = $7.4 billion.

The final linear model for retail sales at bookstores from 1990 through 1997 is s(T) = 0.63T + 7.4.

To estimate the retail sales at bookstores in 2012, we plug T = 22 (because 2012 is 22 years after 1990) into our linear model: s(22) = 0.63*22 + 7.4 ≈ $21.46 billion. So, the estimated retail sales in bookstores in 2012 were about $21.46 billion.

The perimeter of a rectangular painting is 318 cm.If the length of the painting is 95 cm, what is its width?

Answers

Answer:

64 cm

Step-by-step explanation:

In a rectangle, two sides opposite each other would be equal to 95. (5 plus 95 is 190. 318 minus 190 is 128. 128 divided by 2 is 64. 64+64+95+95=318.

The length of the rectangle is 64
