A drawing has a scale of 1:40
On the drawing, a kitchen is a rectangle measuring 14 cm by 22 cm
A bedroom has an actual area of 500 000 cm?
How much smaller, in cm2, is the kitchen than the bedroom?

Answers

Answer 1
Area of kitchen = (14*40)(22*40) = 448,000 sq cm

500,000 - 448,000 = 52,000
The kitchen is 52,000 square centimeters smaller than the bedroom.

Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she should put into each bag?

Answers

Answer:

Softballs = (48/b)

Step-by-step explanation:

Given that,

Total number of softballs = 48

She wants to divide them evenly among b softball bags.

We need to find an expression that represents how many softballs she should put into each bag.

As it is dividing among b softball, it means we divide 48 and b. So,

[tex]s=\dfrac{48}{b}[/tex]

Hence, the required expression is (48/b).

Share 48 in the ratio 3 : 5

Answers

Answer:

18 : 30

Step-by-step explanation:

3 + 5 = 8 (Total units)

48 ÷ 8 = 6

3 units = 6 x 3 = 18

5 units = 6 x 5 = 30

So it's 18 : 30

18:30

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out the maximum amount of profit the company can make, to the nearest dollar.

y=-x^2+90x-454

Answers

9514 1404 393

Answer:

  $1571

Step-by-step explanation:

If we assume that y is profit in dollars, the maximum value of y is revealed by a graph to be ...

  ymax = $1571

The maximum profit the company can make is $1571 at a selling price of $45 each.

_____

The function can be written in vertex form as ...

  y = -(x^2 -90x) -454

  y = -(x^2 -90x +45^2) -454 +45^2

  y = -(x -45)^2 +1571

Because the leading coefficient is negative, we know this vertex represents a maximum. (x, y) = (45, 1571) at the vertex. Maximum profit is $1571.

Edwin bought 3 cds and 7 dvd for $80 Jessica bought 6cds and 3 dvds for $63.75 which system of equation could be used to determine how much one cd and one dvd cost

Answers

Answer:

The system of equations 3x + 7y = 80 and 6x + 3y = 63.75 can be used to determine the cost of one CD and one DVD.

Step-by-step explanation:

Given that:

Cost of 3 CDs and 7 DVDs = $80

Cost of 6 CDs and 3 DVDs = $63.75

Let,

x be the cost of one CD

y be the cost of one DVD

According to given statement;

3x + 7y = 80

6x + 3y = 63.75

Hence,

The system of equations 3x + 7y = 80 and 6x + 3y = 63.75 can be used to determine the cost of one CD and one DVD.

2# Cierra is keeping track of the amount of money in her lunch account each week. She writes the equation A = -6w + 40. What number represents the rate of change?

Answers

Answer:

The rate of change is the slope

In this case

m=2d+50 is a slope intercept equation.

where m is where the y would be

the 2 which is originally where the slope or (m) would be

the d for the (x)

and 50 for the y intercpet or (b)

so

#1=2

The expalantion is the same but different numbers, when asked for the rate of change look at the slope or the number next to the variable. Also put it in y=mx+b form to make sure the number is correct.

#2= -6
