Answer:

She will lift 383 units.

Step-by-step explanation:

The amount of weight that she can lift after x cycles is given by:

W(x) = 315(1.05)^x

How much will she lift after 4 training cycles?

This is W when x = 4, that is, W(4). So

W(x) = 315(1.05)^4 = 383

She will lift 383 units.

kell works at an after-school program at an elementray school. on monday he work for 1.5 hours and recived 12.6 dollars, on tues
Rina8888 [55]

Answer:

Kell would make more money working 10 hours than Markio.

Step-by-step explanation:

To find how much Kell makes per hour, you have to divide how much he worked by how much he earned. So on Monday, Kell worked 1.5 hours and received 12.6 dollars. Divide 12.6/1.5 and you'll find you're answer.

Monday:   12.6/1.5=<u>8.4</u>

On Tuesday, the problem states that he worked 2.5 hours and received 21 dollars. Divide 21/2.5 and you'll find the answer.

Tuesday:     21/2.5= <u>8.4</u>

On Wednesday, the problem states that he worked 4 hours and received 33.60. Divide 33.60/4 and you'll get you're answer.

Wednesday:    33.60/4= <u>8.4</u>

So we can conclude that Kell makes $8.40 per hour.

Now the problem states, Markio gets paid 7 dollars per hour. To find the answer to the question, you have to multiply how much they make per hour times 10 hours.

Markio:  7x10=70

Kell:  8.4x10=84

So to answer the question, Kell would make more money working 10 hours.

lamar has 1354.5 Kilograms of potatoes to deliver equally to 18 stores 12 of the stores are Bronx how many kilograms of potatoes
Novay_Z [31]

903 kg of potatoes will be delivered to stores in Bronx

<em><u>Solution:</u></em>

Given that, lamar has 1354.5 Kilograms of potatoes to deliver equally to 18 stores

12 of the stores are Bronx

Number of stores in Bronx = 12

From given,

Kilograms of potatoe = 1354.5 kg

Total number of stores = 18

<em><u>Let us first find the kilograms of potato delivered to 1 store</u></em>

\text{kg of potato to 1 store } = \frac{\text{Total kg of potato}}{\text{ total number of stores}}

Substituting the values we get,

\text{kg of potato to 1 store } = \frac{1354.5}{18} = 75.25

Thus 75.25 kg potato is delivered to 1 store

<em><u>How many kilograms of potatoes will be delivered to stores in Bronx</u></em>

Number of stores in bronx is 12, so multiply 75.25 by 12

\rightarrow 12 \times 75.25 = 903

Thus 903 kg of potatoes will be delivered to stores in Bronx

there are three people who work full-time and are to work together on a project but their total time on the project is to be equ
zhuklara [117]
This would be:
1 - \frac{1}{2} - \frac{1}{3}

Using common denominator of 6:
\frac{6}{6}- \frac{3}{6}- \frac{2}{6} =  \frac{1}{6}

They should use \frac{1}{6} of their time.
