Answer:

$552.50

Step-by-step explanation:

To find how much she will make, find 6.5% of 8500

8500(0.065)

= 552.5

So, she will make $552.50

Answer:

$552.50

Step-by-step explanation:

The formula we'll use for this is the simple interest formula, or:

[tex]I=P*R[/tex]

Where:

P is the principal amount, $8500.00.

R is the interest rate, 6.5% per year, or in decimal form, 6.5/100=0.065.

To find the simple interest, we multiply 8500 × 0.065 to get that:

The interest is: $552.50

Answer:

Area of triangle is 1 inches²

Step-by-step explanation:

We are given:

Base of triangle = 16 inches

Height of triangle = [tex]\frac{1}{8} \:[/tex] inches

We need to find:

Area of triangle

The formula used to find Area of triangle is:

[tex]Area \:of\: triangle=\frac{1}{2}\times b \times h[/tex]

where b is base and h is height.

Putting values and finding area:

[tex]Area \:of\: triangle=\frac{1}{2}\times 16 \times \frac{1}{8}\\ Area \:of\: triangle=\frac{16}{16}\\ Area \:of\: triangle=1\:inches^2[/tex]

So,  Area of triangle is 1 inches²

Step-by-step explanation:

ax2 + bx + c = 0

-2 = -x + x2 - 4

-1x + 1x2 - 2 = 0

1x2 - 1x -2 = 0

Answer:

y - 0 = -⅔(x - 3)

Step-by-step explanation:

Given a point, (a, b) and slope, m, equation of the line in point-slope form can be written.

Thus:

Substitute (a b) = (3, 0), and m = -⅔ into y - b = m(x - a).

y - 0 = -⅔(x - 3) (the equation in point-slope form)

Step-by-step explanation:

8(-10x+3.5y-7) = -80x + 28y -56

4(-20x+7y-14) = -80x +28y -56

Answer:

the first answer

Step-by-step explanation:

if a and x are the same and a has an angle of 45 degrees that means that x has an angle of 45 degrees

The required condition that must be true is,
(a) ∠x = 45°
(c) YZ = 3 cm

Incongruent geometry, the shapes that are so identical. can be superimposed to themselves.

Here,
For the given triangle to be congruent,
Each pair of corresponding angles and sides must be equal,
So,
(a) ∠x = 45°

When applying the cosine formula,
we get,
(c) YZ = 3 cm

Thus, the required condition that must be required to be to make the triangle congruent are,
(a) ∠x = 45°
(c) YZ = 3 cm

Answer:

The side length of the new square is 24 ft.

Step-by-step explanation:

Dilations

A dilation is a transformation that produces a new image that is the same shape as the original but of a different size.

A dilation stretches or shrinks the original figure. To describe a dilation it's usually included the scale factor (or ratio) and the center of the dilation.

We have a square with a side length of 36 ft. When this square is dilated by a scale factor of 2/3, the new square will have a side length of 36*2/3= 24 ft.

The side length of the new square is 24 ft.

Answer:

24 feet

Answer:

y = -x + 6

Step-by-step explanation:

Since the slope is -1, there is another point at (6,0), which is the x-intercept. The y-intercept is (0,6). The slope and y-intercept are then plugged into the slope-intercept form equation to get y = -x + 6

Answer:

0.9772 = 97.72% probability that a randomly generated value of X is greater than a randomly generated value of Y

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

[tex]\mu_X = 45, \sigma_X = 4, \mu_Y = 35, \sigma_Y = 3[/tex]

What is the probability that a randomly generated value of X is greater than a randomly generated value of Y

This means that the subtraction of X by Y has to be positive.

When we subtract two normal variables, the mean is the subtraction of their means, and the standard deviation is the square root of the sum of their variances. So

[tex]\mu = \mu_X - \mu_Y = 45 - 35 = 0[/tex]

[tex]\sigma = \sqrt{\sigma_X^2+\sigma_Y^2} = \sqrt{25} = 5[/tex]

We want to find P(X > 0), that is, 1 subtracted by the pvalue of Z when X = 0. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0 - 10}{5}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

1 - 0.0228 = 0.9772

0.9772 = 97.72% probability that a randomly generated value of X is greater than a randomly generated value of Y

Answer:

63 ft

Step-by-step explanation:

We solve this question using Trigonometric function of Cosine

cos θ = Adjacent/Hypotenuse

From the question:

θ = 23°

Adjacent = The distance of the fisherman from shore = 58 ft

Hypotenuse = The distance of the fisherman from the bird = x ft

Hence:

Cos 23 = 58/x

Cross Multiply

Cos 23 × x = 58

x = 58/Cos 23

x = 63.00890189 ft

Approximately = 63 ft

The distance of the fisherman from the bird is 63 ft
