6 Mrs. Baker uses 7.5 cups of sugar to make
14 dozen cookies. To the nearest hundredth,
what is the rate of cups of sugar per cookie?
© 22.4 cups
s?
@ 0.45 cup
Ⓡ 0.04 cup
☺ 0.54 cup



What is the answer

Answers

Answer:

Option C: 0.04 is the correct answer.

Step-by-step explanation:

Given that:

cups of sugar used = 7.5

cookies = 14 dozen

As we know that 1 dozen cookies equal 12 cookies so,

14 dozen cookies = 14* 12 = 168 cookies

Now,

we have to find the rate of cups of sugar per cookie, So:

Rate = cups of sugar / total cookies

By putting values:

Rate = 7.5/ 168

By simplifying we get

Rate = 0.04464

By rounding it off to nearest hundred:

Rate = 0.04

Hence the rate of cups of sugar per cookie is 0.04

What is 5 thousand + 7 thousand in standard form

Answers


5000 + 7000 = 12000

5 x 10^4 + 7 x 10^4 = 12 x 10^4
Standard: 5,000 + 7,000 = 12,000
                   /                \                \
        5 thousand + 7 thousand = 12 thousand.

Which property is shown? –7 + 24 = 24 + (–7) A. associative property B. distributive property C. opposite of a sum property D. commutative property

Answers

B Commutative Property
This is the commutative property. This is because the commutative property just moves stuff around for example a+b = b+a, is the commutative property. The associative property is a+(b+c) = (a+b)+c, the distributive property is a(b+c) = ab+ac, and the opposite of a sum property is -(a+b) = (-a)+(-b).

Linear functions can be written in y=mx and y=mx+b. In which form is the linear function in the example problem? What are the values of m and b and what do they represent?

Answers

Answer:

M is 1 it is the slope. B is 2 it is where the slope crosses the y axis.

Step-by-step explanation:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0) or (0,y)


y = mx

"m" is the slope (the y-intercept is 0/it crosses the origin (0,0))


When x = 0, y is 2, so the y-intercept is 2.

You can find the slope by using the slope formula and plugging in two points, or you use this:

slope=(rise)/(run)

Rise is the number of units you go up(+) or down(-)

Run is the number of units you go to the right.


If you look at the graph, from each point, you go up 1 unit, and to the right 1 unit. So the slope is 1/1 or 1.


y = mx + b

m = 1  and it represents the slope of the line

b = 2 and it represents the y-intercept of the line

y = 1x + 2   or    y = x + 2
