The answer would be A.

Explanation:

If they enter with one car, that’s a price of $3 for the car alone. Because there’s also a fee for each person who enters, and there is a family of 5 who enters, x is representative of the cost for each person who enters. Therefore, there would be 5 x’s and one 3 that when solved would add up to the total of $45 they spent. That would mean A is correct because the equation would be x + x + x + x + x + 3 = 45.

Nadya [2.5K]

Answer:

(-3,-3)

Step-by-step explanation:

If we reflect P (0,0) across x=-3 and then across y=-3, then the new point of P would be (0-3,0-3)=(-3,-3)

a window is shaped like a parallelogram. the height of the window is half the length of the base of the window. the base of the

rusak2 [61]

The area of the parallelogram is 36 inches square.

We have a parallelogram shaped window whose dimensions are as follows-

base (b) : 12 inches

height (h) : $\frac{1}{2} \times 12$ = 6 inches

Other side = 10 inches

We have to find the area of the window.

<h3>What is the formula to calculate the area of a parallelogram of given base (b) and height (h).</h3>

The area of the parallelogram is given by -

$A = \frac{1}{2} \times base\times height$

In the question given - We can apply the above formula to estimate the area of the window.

A = $\frac{1}{2} \times 12\times6$ = 36 inches square.

Hence, the area of the parallelogram is 36 inches square.

In how many ways can the first 4 guests arrive at a party if 15 guests have been invited.

notsponge [240]

Answer:

The first 4 guests can arrive in 32,760 ways.

Step-by-step explanation:

The order in which the guests arrive is important. For example, A,B,C,D is a different outcome to B,A,C,D. So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this question:

4 guests from a set of 15. So

$P_{(15,4)} = \frac{15!}{(15-4)!} = 32760$

The first 4 guests can arrive in 32,760 ways.

At 5 p.m., the total snowfall is 2 centimeters. at 10 p.m., the total snowfall is 10 centimeters. what is the mean hourly snowfa

TEA [102]

Answer:

The mean hourly snowfall is 2.5 centimeters

Step-by-step explanation:

The mean hourly snowfall is the number of centimeters that fell during the period divided by the number of hours.

From 5 P.M. to 9 P.M., there are 4 hours

At 5 P.M., the total snowfall is 2 centimeters.

At 9 P.M., the total snowfall is 12 centimeters.

So in those four hours, the depth of snow increases 12-2 = 10 centimeters

10/4 = 2.5

The mean hourly snowfall is 2.5 centimeters
