A gardener is planting two types of trees: Type A is 7 feet tall and grows at a rate of 2 inches per year. Type B is 2 feet tall
arsen [322]

Answer: it will take 0.33 years for the heights to be the same.

Step-by-step explanation:

Let x represent the number of years it will take for both trees to be the same height.

Type A is 7 feet tall and grows at a rate of 2 inches per year. This means that the height of the tree after x years would be

2x + 7

Type B is 2 feet tall and grows at a rate of 17 inches per year. This means that the height of the tree after x years would be

17x + 2

For the heights to be the same, the number of years would be

17x + 2 = 2x + 7

17x - 2x = 7 - 2

15x = 5

x = 5/15

x = 0.33 years

How do I simplify 3(2a-8b)
Mumz [18]
You would have to do distribution. So you would have to multiply 3 by 2a and multiply 3 by -8b. 3 times 2a equals 6a (always keep the letter) and 3 times -8b equals -24b. (if there is only one negative number when multiplying, always keep the negative sign.) now you are left with 6a-24b. and since we cant put a into b, your answer would be 6a-24b. hopefully this helped you and sorry if it confused you

The titanium content of an alloy is being studied in the hope of ultimately increasing the tensile strength. An analysis of six
HACTEHA [7]

Answer:

Tstatistic = - 3.068

Step-by-step explanation:

Given the data: 9.7% 7.4% 5.9% 7.7% 7.5% 8.9%

Mean titanium > 9.5%

Test statistic :

(m - μ) / (s/√n)

From the data: obtain the sample mean and standard deviation

From the data given ;

Calculate the same mean and standard deviation :

Using calculator :

Sample mean (m) = ΣX / n

Sample size (n) = 6

m = 47.1 / 6 = 7.85

Standard deviation (s) :

Using calculator = 1.317

Hence,

(m - μ) / (s/√n)

Tstatistic = (7.85 - 9.5) / (1.317/√6)

Tstatistic = - 1.65 / 0.5376629

Tstatistic = - 3.068

17. Mike has $50 more than Kemone has. Together they have $730. How much does Kemone have?
kakasveta [241]

Answer:

340

Step-by-step explanation:

$730 - $50 = $680

$680 / 2 = 340

they both have an equal of 340 and then mike adds in 50 more so:

340 + 340 = 680 + mike's $50 = $730.
