Answer:

Open Circle from 3 to -10

Step-by-step explanation:

M is less than 3 in this equation (because the "mouth" is eating the bigger variable, 3) so the graph goes from 3 and down. The circle is open because the symbol is (<) I think of it like this: the closed circle has more to it because you have to color it in. The (≥) symbol also has more to it because it has a line below it. So maybe use that to think about. Have a nice day!

Cyndee is taking her siblings out for dessert. Ice cream, c, costs $4.00 per cone. Brownies, b, are $2.00 each. Water for everyo
GalinKa [24]

Answer:

The term that represent the amount of money she will spend on brownies is 2b

Step-by-step explanation:

Let

c ----> the number of cones

b ----> the number of brownies

we know that

The cost of desserts can be found using the expression

4c+2b+5

where

4c ----> is the term that represent the amount of money spend in cones

2b ----> is the term that represent the amount of money spend in brownies

5 ----> is the term that represent the amount of money spend in water

therefore

The term that represent the amount of money she will spend on brownies is 2b

That means ---> the number of brownies (b) multiplied by the cost of each brownie ($2)

One circle has a diameter of 6 inches. A larger circle has a diameter that is 4 times the diameter of the circle. what is the ra
harina [27]

Answer:

C, 1 : 16

Step-by-step explanation:

Small Circle

The radius is half of the diameter. 3 inches.

π×r²=A

We'll use 3.14 for pi.

3.14×9

28.26 in²

Bigger Circle

6×4= 24

So the diameter is 24. The radius is 12.

3.14×12²

3.14×144

452.16 in²

Let's divide.

452.16÷ 28.26

= 16

Therefore, the answer is C, 1 : 16.

Hope this helps, please mark brainliest if possible :)

What’s the answer hurry
Rina8888 [55]

Answer:

Choice C: Lauren is faster than Kevin, slower than Jeremy.

Step-by-step explanation:

Ok, so it directly says that Jeremy is going at y=12x, or 12 miles per hour. To find how fast Kevin is riding, take two points of the table and use the slope formula to get the speed(.

Slope Formula: (y2-y1) / (x2-x1)

So lets take the table plots (2, 22) and (4, 33) to do this.

(y2-y1) / (x2-x1)

(33-22) / (4-2)

(11) / (2)

The speed of Kevin is 5.5 miles by hour.

Then, it asks for how fast Lauren is going, saying she is twice as fast as Kevin. Therefore, simply do:

5.5 * 2 = 11 miles per hour

To get the third biker's speed.

Now, with all of the speeds of the bikers, we can now compare them. Here's a listing of their speeds to make things easier to compare:

Jeremy: 12 mph

Kevin: 5.5 mph

Lauren: 11 mph

From this, we can see that Lauren is the second fastest. She is slower than Jeremy but faster than Kevin. Therefore, the correct answer choice is C.
