mario62 [17]

Answer:

B

Step-by-step explanation:

We are given f(x) is height in cm while x is days old.

We are also given f(60)=210.

If you compare f(60) to f(x) you should see that x is 60 so we have the sunflower is 60 days old. Since f(60)=210, then you have the height of the sunflower is 210 cm tall.

Jena's income is $1600 a month, and she plans to budget 1/3 of her income for rent and 1/8 of her income for groceries. Step 2 o

WARRIOR [948]

Answer:

Jena spends $ 733. 33 on her rent and groceries altogether per month.

Step-by-step explanation:

Jena's total income in a month= $1600

Here , expenditure on rent = (1/3) of her income

So, now one- third of her income $1600 is

= $\frac{1}{3} \times 1600 = 533.33$

or, (1/3) of her salary is $533. 33

Hence, Jena spends $ 533. 33 on her rent monthly.

Now, her expenditure on groceries = (1/8) of her income

So, now one- eighth of her income $1600 is

= $\frac{1}{8} \times 1600 = 200$

or, (1/8) of her salary is $ 200.

Jena spends $ 200. on her groceries monthly.

So, Total expenditure = Expenditure on rent + Expenditure on groceries

= $533. 33 + $200 = $733.33

Hence, Jena spends $ 733. 33 on her rent and groceries altogether per month.

Jason runs around a 400-meter track for training. During the month of September he ran around the track 520 times. How many kilo

marishachu [46]

Answer:

208 km

16 tablets per day

Step-by-step explanation:

Given:

Length of training track run by Jason = 400 m

Number of times Jason ran on the track = 520

Therefore,

The total length covered by Jason = 520 × 400 = 208,000 m

now,

1 Km = 1000 m

thus,

208,000 m = $\frac{\textup{208000}}{\textup{1000}}$

or

= 208 km

b) Amount of calcium carbonate in a tablet = 500 mg = 0.5 g

Maximum amount of calcium carbonate that can be taken = 8 g

hence,

the maximum number of tablets that she can take

= $\frac{\textup{Maximum amount of calcium carbonate that can be taken}}{\textup{Amount of calcium carbonate in a tablet}}$

= $\frac{\textup{8}}{\textup{0.5}}$

= 16 tablets per day
