A plant is 30cm tall when planted in a garden it increases by 10 percent each week how long will it take to reach 1 meter

belka [17]

Answer:

12.63 weeks ~~ 13 weeks

Step-by-step explanation:

This is much like a banking question with compounded interest

FV = PV ( 1 + i)^n FV = Future value = 1 m PV = present value = .3

i = periodic interest = .10 n = periods

1 = .3(1 + .1)^n solve for n = the number of weeks

1/.3 = 1.1^n

log (1/.3) / log 1.1 = n = 12.63 weeks

The total cost, C, for running an advertisement in a local newspaper, The Free Press, is made up of an initial cost of $12 plus

allochka39001 [22]

There is no clear question here, however, the plan for the local newspaper, if the plan is long-term, is more comfortable for the consumers, but less comfortable if it is short-term.

Using a sample size of two days.

- For the local newspaper, we have

($5 × 2) + ($12) = $22

- For the rivals, we have

$8 × 2 = $16

Using a sample size of one hundred days.

- For the local newspaper, we have

($5 × 100) + ($12) = $512

- For the rivals, we have

$8 × 100 = $800

Mike spent $7920 on his vacation, which was 11% of his monthly salary. What was his monthly salary?

oksian1 [2.3K]

Amount spent on vacation=$7920,

Let Mike monthly salary be x,

11% of X= $7920,

$\frac{11}{100} \times x = 7920$

$11x = 7920 \times 100$

$x = 792000 \div 11$

$x = 72000$

If 10% of a group ate sandwiches two days in a row, and 40% of the group had a sandwich on the first day, this means that 25% of

Charra [1.4K]

The problem can be represented on a Venn diagram, as shown below.

We have P(Day 1 ∩ Day 2) = 0.1 and P(Day 1) = 0.4
We can deduce that 30% of the group ONLY had sandwiches on Day 1 and there's 60% of the group ONLY had sandwiches on Day 2.

We obtain the value 60% = 0.6 from 100%-(10%+30%)=60%

We also can deduce that there 70% of the group that had sandwiches on Day 2

The proportion of people who ate sandwiches on Day 2 GIVEN that they ate sandwiches on Day 1 is given by

P(Day 1 ∩ Day 2)÷P(Day 2) = 0.1÷0.4 = 0.25 = 25%

The statement is TRUE
