The area of the triangle below is 38.28 square meters. What is the length of the base?

Answer:

D-2

Step-by-step explanation:

You can use elimination to get the value of y. Move numbers to one side and x and ys to the other side. To use elimination, multiply the first equation with 2. You will get 2x+2y=24. add it with the equation below. y will be eliminated and you will get the value of x. X=10. Plug in x and get the y value. Y=2

Answer:

Cost of the box of pencils = x = $4

Cost of the notebook = x+2 = 4+2 = $6

Cost of package of pens = 3x = 3(4) = $12

Step-by-step explanation:

Let the cost of the box of pencils = x

Cost of the notebook = 2 more than the pencils cost = x+2

Cost of package of pens = 3 times the pencils cost = 3x

The total was $22, so we can say:

(x)+(x+2)+(3x) = 22

5x=22-2

x=20/5

x=$4

Cost of the box of pencils = x = $4

Cost of the notebook = x+2 = 4+2 = $6

Cost of package of pens = 3x = 3(4) = $12

The population of deer at time t=3 years is approximately 4128 deer.

An exponential function is a mathematical function of the form [tex]f(x) = a^x[/tex], where a is a positive constant called the base, and x is the input variable. The exponent x represents the power to which the base a is raised.

The rate of growth of the deer population is given by the function [tex]R(t) = 2000e^{(0.231t)}[/tex], where t is the time in years since t=0.

To find the population at time t=3, we need to evaluate R(3) using the given function:

[tex]R(3) = 2000e^{(0.231\times 3)[/tex]

[tex]R(3) = 2000e^{0.693}[/tex]

R(3) ≈ 4127.72

Therefore, the population of deer at time t=3 years is approximately 4128 deer.

Answer:

At t = 9, Whitney's acceleration will be -0.2 miles per minute.

Step-by-step explanation:

Remember that the acceleration is the derivative of velocity.

Since we want to find Whitney's acceleration at t = 9 and we are given the velocity function, we can simply find the derivative of the point at t = 9. In other words, a(9) = v'(9).

For the interval (7, 11), we simply have a line. So Whitney's acceleration at t = 9 will be equivalent to the slope of that line.

We have the two points (7, 0.8) and (11, 0). So, the slope between them is:

[tex]\displaystyle m=\frac{0-0.8}{11-7}=\frac{-0.8}{4}=-\frac{1}{5}[/tex]

So, a(t) = v'(t) = -0.2 ∀t ∈ {t | 7 < t  < 11}. Then at t = 9, Whitney's acceleration will be -0.2 miles per minute.

Answer:

$817.78

Step-by-step explanation:

To find the tax you must do the equation:

751.98 x 0.0875

(Btw, 0.0875 is decimal form of 8.75%. Always turn the percentage into a decimal before finding the tax or sale amount)

751.98 x 0.0875 = 65.80.

Now, add the sale tax amount and the original price:

751.98 + 65.80 = 817.78

Therefore, the answer is 817.78.

Answer:

Children=21 Adult=35

Step-by-step explanation:

[using c for children tickets and a for adult tickets]

56=c+a and 203=3c+4a [starting system of equations]

a=56-c ---> 203=3c+4(56-c) [plugging the first eq. into the second]

203=3c+224-4c [simplify]

-21=-c [simplify 2.0]

c=21 [simplify 3.0]

56=21+a [plugging back into org. eq.]

so a=35

Answer:

The product of two rational numbers is rational.

So, multiplying two rationals is the same as multiplying two such fractions, which will result in another fraction of this same form since integers are closed under multiplication. Thus, multiplying two rational numbers produces another rational number.

The total area is 45 square inches.

This question requires your knowledge about the area of compound shapes. For solving this, you should:

The figure is composed of:

Therefore, you should sum the area of these geometric figures for determining the given  area.

Area of each square =  a², where a=the length of the side.

Like, the length of the side is equal to 3 in, the area will be:

A_square= 3²=9 in².

You have two squares in the figure. Then, the total area for the squares is 9 + 9 =18 in²

Area of the rectangle = bh . The figure shows that:  the base = 9 in and the 3=8 in

Thus,  A_rectangle=bh= 9*3=27in²

A_total= A_squares+ A_rectangle

A_total= 18+27=45 in²

A_total= 45in²

Answer:

(5.097, 7.404)

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 40 - 1 = 39

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 39 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.6849

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.6849\frac{4.33}{\sqrt{40}} = 1.154[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 6.25 - 1.154 = 5.096 hours

The upper end of the interval is the sample mean added to M. So it is 6.25 + 1.154 = 7.404 hours.

The answer is  (5.097, 7.404)

Answer:

a.) the effect of one independent variable depends on the levels of the second variable

Step-by-step explanation:

In regression, an interaction effect comes to play whenever the effect that an independent variable has on a dependent variable changes, as regards to value(s) of other independent variables( one or more variables). The variables that give interaction effect as a result of interaction with each other is reffered to as "interacting variables" For instance, in a research whereby how "Male gender versus female gender" and their " dieting B and dieting D" influence their " weight loss" There would be interaction effect in a situation where by a " female gender" that operate on " diet B" shed more weight compare with " male gender" that operate on " diet B". It should be noted that two variables are said to interact when the effect of one independent variable depends on the levels of the second variable
