The area is the product of two dimensions so the ratio of areas is:

The area of ΔDEF:

Answer:

5

Step-by-step explanation:

If you subtract the same thing from both sides, and you are left with 0 = 0, there are infinitely many solutions.

5x + 5 = 5x + ____

Subtract 5x from both sides.

5 = ____

What do you need on the right side, so that when you subtract the same number from both sides you end up with 0 = 0? Answer: 5.

5 = 5

Subtract 5 from both sides.

0 = 0

Let's go back to the original problem, and use a 5 in the blank.

5x + 5 = 5x + 5

Subtract 5x from both sides, and subtract 5 from both sides.

0 = 0

Since 0 = 0 is a true statement, the equation is true for every value of x.

Answer: 5

Answer:

[tex]\sin(N) = 0.66[/tex]

Step-by-step explanation:

Given

[tex]\angle P = 90^o[/tex]

[tex]PO = 48; NP = 55; ON = 73[/tex]

Required

[tex]\sin(N)[/tex]

The given parameters is illustrated with the attached image.

From the attached, we have:

[tex]\sin(N) = \frac{Opposite}{Hypotenuse}[/tex]

[tex]\sin(N) = \frac{PO}{ON}[/tex]

[tex]\sin(N) = \frac{48}{73}[/tex]

Answer:

Step-by-step explanation:

The total cost for the laptop for 3 years is $1174.20.

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

Given that,

Cost of the laptop when purchased = $780

Daily cost = $0.36

Number of days in 3 years = 3 × 365 = 1095 days

Cost for the laptop for 3 years = 1095 × $0.36

                                                   = $394.20

Total 3 year cost = $394.20 + $780

                            = $1174.20

Hence the total cost for the laptop is $1174.20.

Answer:

A. 55°

Step-by-step explanation:

Complementary angles are angles that add up to give us 90°.

Since <A and <B are complementary angles, it implies that:

m<A + m<B = 90°

If m<A = 35°, therefore:

35° + m<B = 90°

Subtract 35° from each side

m<B = 90° - 35°

m<B = 55°

Answer:

4, 860 yards

Step-by-step explanation:

To find area multiply l*w. So, multiply 90 by 54 to get your answer:

90 yards × 54 yards = 4, 860 yards

if rectangular field is 90 yards long and 54 yards wide then the area of the field is 4860 square yards.

The area of Rectangle is length times of width.

Given that Grass seed is going to be spread over a playing field.

The number of bags of seed needed depends on the size of the field.

The rectangular field is 90 yards long and 54 yards wide.

We need to find the area of the field.

Length of field = 90 yards

Width of field = 54 yards

Area of Field = Length×Width

=90×54

=4860 square yards.

Hence, if rectangular field is 90 yards long and 54 yards wide then the area of the field is 4860 square yards.

Answer:

The equation that best represents this model is [tex]P(x) = 10000(1.08)^x[/tex]

Step-by-step explanation:

Exponential equation for population growth:

The exponential equation for population growth, after x years, is given by:

[tex]P(x) = P(0)(1+r)^x[/tex]

In which P(0) is the initial population and r is the growth rate.

A model predicts that the population of a certain town was 10,000 in 2001.

This means that [tex]P(0) = 10000[/tex]

8% yearly increase.

This means that [tex]r = 0.08[/tex]. So

[tex]P(x) = P(0)(1+r)^x[/tex]

[tex]P(x) = 10000(1+0.08)^x[/tex]

[tex]P(x) = 10000(1.08)^x[/tex]

The equation that best represents this model is [tex]P(x) = 10000(1.08)^x[/tex]

Answer:

P(25 < x < 37) = 0.77

Step-by-step explanation:

Given - If a Variable has a normal distribution with mean 30 and standard deviation 5

To find - find the probability that the variable will be between 25 and 37.

Proof -

Given that,

Mean, μ = 30

S.D, σ = 5

Now,

[tex]z = \frac{x-\mu}{\sigma}[/tex] ~ N(0,1)

Now,

P(25 < x < 37)

= [tex]P(\frac{25 - 30}{5} < z < \frac{37 - 30}{5} )[/tex]

= P(1 < z < 1.4)

= P(z < 1.4) - P(z < -1)

= 0.9192 - 0.1587

= 0.7605

≈ 0.77

∴ we get

P(25 < x < 37) = 0.77

Answer:

x = 1    y = 3    z = 1

Step-by-step explanation:

(1)  x - 3y - z = -9           (2)   -2x + y + 2z = 3        (3)   2x + y + 3z = 8

                                2x(1)     2x - 6y - 2z = -18      (2)  -2x + y + 2z = 3

                                                 - 5y = -15                           2y + 5z = 11

                                                      y = 3                            2(3) + 5z = 11

                                                                                            6 + 5z = 11

                                                                                                  5z = 5

                                                                                                    z = 1

       x - 3(3) - 1 = -9

       x - 9 - 1 = -9

            x - 10 = -9

            x = 1

Answer: Choice B is correct.

==================================================

Explanation:

We are told that the derivative function f ' (x) is positive for all real numbers x. This means that f(x) is increasing for all real numbers. An increasing function goes uphill as you move from left to right. This rules out choices C and D.

We're also told that the integral of f(t), from t = 4 to t = 7, is equal to 0. Because f(x) is increasing, this must mean that some portion of f(x) is below the x axis and some portion is above the x axis when focused on the interval of [tex]4 \le x \le 7[/tex]. This allows us to rule out choice E since there are no portions that are below the x axis here.

At this point, the answer is between A and B. We can rule out choice A for similar reasoning we did with choice E. This time, there is no portion that is above the x axis. We need a negative area (below the x axis) to counterbalance with a positive area (above the x axis) so that the two areas cancel out and add to 0. That doesn't happen with choice A.

The only thing left is choice B so that must be the answer. We have a portion below the x axis and a portion above it, so it's possible that these two areas cancel out to add to 0. Since we don't know the actual f(x) function, it's impossible to tell whether that happens or not.
