Answer:

The triangle with side lengths 7 in, 11 in, 13 in will be an acute angled triangle.

Step-by-step explanation:

If we assume that the triangle with height 7 inches and base 11 inches of a right triangle then its hypotenuse will have the length of

$\sqrt{7^{2} + 11^{2}} = \sqrt{170} = 13.04$ inches.

But the third side of the triangle is given to be 13 inches which is less than 13.04 inches i.e. 13 < 13.04.

Therefore, the triangle with side lengths 7 in, 11 in, 13 in will be an acute-angled triangle. (Answer)

Determine whether the data set is a population or a sample. Explain your reasoning. The salary of each teacher in a school. Choo

SVETLANKA909090 [29]

Answer:

D. Population, because it is a collection of salaries for all teachers in the school.

Step-by-step explanation:

In research, population refers to a complete set of subjects that share a characteristic and that the researcher is interested in. On the other hand, a sample is a subset of a population and it's usually the one the researcher takes to make a study with.

In this example, we have "The salary of each teacher in a school" since we are taking ALL the teachers of this school, this would be a population. If we were working with the salary of only a portion of the teachers of said school, it would be a sample.

Thus, the right answer is D. Population, because it is a collection of salaries for all teachers in the school.

A van travels from Town A to Town B. It uses 1 gallon of gas for every 24 miles traveled. A) How many gallons of gas does the va

Setler79 [48]

Answer:

A) $\frac{x}{8}$ gallons

B) Distance between Town A and Town B is $48y$ miles

Step-by-step explanation:

We know, number of gallons = $\frac{DistanceTravelled}{MilesPerGallon}$

if miles per gallon (mpg) is given as 24 & total distance travelled is 3x miles, then, using formula we have:

Number of Gallons = $\frac{DistanceTravelled}{MilesPerGallon}=\frac{3x}{24}=\frac{x}{8}$

Now, given is number of gallons = 2y & we know mpg is 24; <em>so what is the distance?</em>

We use the same formula and solve for distance (let distance between A and B be "D"):

$NumberOfGallons=\frac{DistanceTravelled}{MilesPerGallon}\\2y=\frac{D}{24}\\D=2y*24\\D=48y$

In order to play in chess tournaments at the Marshall Club, Malik pays a fee to become a member. In addition, he pays a set rate

Keith_Richards [23]

Answer:

p = 22.50 + 15t

Step-by-step explanation:

For Malik :

Membership fee = m

Rate per tournament = t

After 4 tournaments :

m + 4t = 85 - - - (1)

After 7 tournaments :

m + 7t = 130 - - - (2)

Subtract 2 from 1

4t - 7t = 85 - 130

-3t = - 45

t = 45 / 3

t = 15

Put, t = 15 in (1)

m + 4(15) = 85

m + 60 = 85

m = 85 - 60

m = 25

Massai pays 10% less membership fee than Malik

Hence, Massai's membership fee:

(100 - 10)% * 25

0.9 * 25 = $22.50

Total price, p, Massai will pay to compete in t tournaments ;

Total price = membership fee + (rate per tournament * number of tournaments)

p = 22.50 + 15t
