Adam buys a box of stuff that weighed 6 3/8. if he buys box of fruit that weighed 7 2/5. what is the combined weight.

jolli1 [7]

Answer:

The combined weight is 13 31/40.

Step-by-step explanation:

Given:

Adam buys a box of stuff that weighed 6 3/8. if he buys box of fruit that weighed 7 2/5.

Now, to find the combined weight.

So, we change the mixed fraction to improper first:

Weight of box of stuff = $6\frac{3}{8}=\frac{51}{8}$ .

Weight of box of fruit = $7\frac{2}{5}=\frac{37}{5}$ .

Then, by adding to get the combined weight:

$\frac{51}{8}+\frac{37}{5}$

$=\frac{51\times 5+37\times 8}{40}$

$=\frac{255+296}{40}$

$=\frac{551}{40}$

$=13\frac{31}{40}$

Therefore, the combined weight is 13 31/40.

If the function graphed is f(x), find f(1).

Crazy boy [7]

Locate 1 on the x axis. This is the horizontal number line.

Draw a vertical line through 1 on the x axis. Extend this vertical line as far up and down as you can.

Notice how the vertical line crosses the blue curve. Mark this point. Then draw a horizontal line from this point to the y axis. The horizontal line will touch -4 on the y axis. So that means the point (1,-4) is on the curve.

If the input it is x = 1, then the output is y = -4

So that's why the answer is choice A

A cellphone company charges $60 for a cellphone and a monthly rate to use the phone.Regina will pay $1,140 for a 24-month cellph

Alinara [238K]

The monthly rate is $45 for this cellphone plan.

Step-by-step explanation:

Given,

Amount charged for cell phone = $60

Amount paid by Regina for 24 month plan = $1140

Number of months = 24

Let,

m be the monthly rate for cellphone plan

Number of months * Monthly rate + cellphone charges = Amount paid

$24m+60=1140\\24m=1140-60\\24m=1080$

Dividing both sides by 24

$\frac{24m}{24}=\frac{1080}{24}\\m=45$

The monthly rate is $45 for this cellphone plan.
