Answer:

Dial it up : ring ring

=8:9

Step-by-step explanation:

From Dial it up= $16 per 2 gb.

ratio of gb : price

2:16

can be reduced to 1:8

this means that per each Gigabyte, you pay $8.

Ring Ring has plans of $9 per 1gb

ratio of gb to price is 1:9

And the ratio between the prices

of the companies is

Dial it up:ring ring

8:9

which means that in one company you get one gb for $8, while in the other company you get the same one gb for $9.

____ [38]

Answer:

Yes.

Step-by-step explanation:

When you add the different amounts needed together ( 1lb 3oz + 1lb 8oz + 2lb 4 oz ), you get 4lb 15oz. Since there are 16oz in a pound, you need less than 5 lb. Therefore, you need less than 5lb, the 5lb bag will be more than enough.

So far this basketball season, Sherita made 46 of her
Tresset [83]

Answer:

<em>Sherita would need to make 10 free throws</em>

Step-by-step explanation:

<u>Proportions</u>

Sherita made 46 of her first 60 free throws in this basketball season. Calculating the average we get:

\displaystyle \frac{46}{60}=76.7\%

Sherita wants to have a free throw average of at least 80% in her next x free throws. This means she will have 46+x made throws out of 60+x total throws. For this new performance, the new average would be:

\displaystyle \frac{46+x}{60+x}

And we equate it to 80% (0.8 in decimal):

\displaystyle \frac{46+x}{60+x}=0.8

Multiplying by 60+x:

46+x=0.8(60+x)

Operating:

46+x=48+0.8x

Subtracting 46 and 0.8x:

0.2x=2

Dividing by 0.2

x = 10

Sherita would need to make 10 free throws
