Answer:

7.91

Step-by-step explanaton:

  Derek wants to determine the height of the top of the backboard on the basketball goal at the playground. He places a standard 12-inch ruler next to the goal post and measures the shadow of the ruler and the backboard. If the ruler has a shadow of 11 inches and the backboard has a shadow of 7.25 feet, then about how high is the top of the backboard?

A.  

6.14 feet

 B.  

8.92 feet

 C.  

7.91 feet

D.  

9.17 feet

i was looking for the answer and jess couldn't find it and so i answered it and it told me the answer was 7.91.

it also told me that the reason for this was:

Since the backboard and the ruler are both vertical and the sun is at the same position in the sky, the triangle made by the backboard and its shadow is similar to the triangle made by the ruler and its shadow.

The ratio of the corresponding sides of the triangles are equal and the height of the backboard can be determined by solving the following proportion.

Therefore, the top of the backboard is 7.91 feet high.

Answer:

Option C is the correct answer

Step-by-step explanation:

Let μ1 be the average flying speed of monarch butterflies and let μ2 be the average flying speed of swallowtail butterflies.

Also, let n1 be the sample size of monarch butterflies and let n2 be the sample size of swallowtail butterflies.

Thus, defining the hypothesis, we have;

Null hypothesis;H0: μ1 = μ2

Alternative hypothesis; H1: μ1 > μ2

In this case, the p-value = P_H0[t_(n1 + n2 - 2) ≥ t] where t is the test statistic based on tbe differences of sample mean,that follows t distribution with degrees of freedom (n1 + n2 - 2)

With respect to the question, the probability of the monarchs and swallowtails flying at the same speed is 0.072.

Thus,

P_H0[t_(n1 + n2 - 2) ≥ t] = 0.072

We can therefore conclude that in this case, the p-value is the probability of observing a difference equal to or greater than the sample difference under the null hypothesis which states that μ1 = μ2, which is 0.072

Thus, option C is the correct answer

Answer:

The correct option is;

b. The probability that monarchs and swallowtails fly at the same speed is 0.072

Step-by-step explanation:

The p- value indicates the probability of which the hypothesis tested, the null hypothesis is true and it is compared against a given confidence level. Whereby the p-value is more than the given confidence level then it indicates that the null hypothesis assumption is correct.

Therefore, whereby the null hypothesis tests proposes the equality of the two means, then at  a 5% confidence level or α = 0.05, whereby p-value = 0.072 > α = 0.05 we accept the null hypothesis and state that the probability that monarchs and swallowtails fly at the same speed is 0.072.

Answer:

the correct answer is B.

Step-by-step explanation:

The system of equations has one solution. Option B is correct.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression,
x² + y² = 1

Now,
Put x = 1
1 + y² = 1
y² = 0
y = 0

Since for the given expression more than one solution can be possible but for the given condition a x = 1 only one solution is possible.

Thus, the system of equations has one solution. Option B is correct.

Given that the triangular prism with height 10 inches.

The side lengths of the base of the triangle are 12 inches, 13 inches and 5 inches.

We need to determine the surface area of the prism.

Surface area of the prism:

The surface area of the prism can be determined using the formula,

[tex]SA=bh+(s_1+s_2+s_3)H[/tex]

where b is the base and h is the height of the triangle.

s₁, s₂, s₃ are the side lengths of the triangle and

H is the height of the prism.

Substituting b = 12, h = 5, s₁ = 12, s₂ = 5, s₃ = 13 and H = 10 in the above formula, we get;

[tex]SA=(12)(5)+(12+5+13)(10)[/tex]

[tex]SA=60+(30)(10)[/tex]

Answer:-5

Step-by-step explanation:

It’s just how it is -5

The coordinate of S' is (1, -5) if the triangle in the diagram is translated 3 units right and 4 units down.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

Let point is (-2, -1)

Now,

Translated 3 units right, the x-coordinate of the point = -2 + 3 = 1

Translated 4 units down, the y-coordinate of the point = -1 - 4 = -5

The coordinate of S' is (1, -5)

Thus, the coordinate of S' is (1, -5) if the triangle in the diagram is translated 3 units right and 4 units down.

Answer: BC = 15

Step-by-step explanation:

Since the triangles are congruent, that means they are the same. So side AB = side EF. Since we know side FD is 15, that means side BC= 15

Final answer:

To find BC when given triangles ABC and DEF are congruent and the perimeter of DEF is 38, subtract the summed lengths of DE and EF from 38 to get the length of DF, which will be equal to BC.

Explanation:

If you are given that triangle ABC is congruent to triangle DEF and the perimeter of DEF is 38 units, to find the length of side BC, we need to first establish that corresponding sides of congruent triangles are equal in length. This means that each side of triangle ABC corresponds and is equal to a side of triangle DEF. Therefore, if you are given the lengths of sides DE and EF, you subtract their sum from the total perimeter of triangle DEF to find the length of side DF. Since triangle ABC is congruent to triangle DEF, BC is equal to DF. Thus, the length of side BC in triangle ABC can be calculated.

For example, if DE is 10 units and EF is 12 units, then:

You would estimate first look at the 100's place 3+2=5 so we already have 500 so we know that the sumis greater than 500 because is you at 61+83 with 500 its a larger number than just 500

Final answer:

To see if 361 + 283 is greater than 500, round each number to the nearest hundred and add them. The rounded sum of 400 + 300 = 700 is clearly greater than 500, thus the actual sum must also be greater than 500.

Explanation:

To determine if the sum of 361 + 283 is greater than 500 without actually adding the numbers together, you can use estimation. You can round each number to its nearest hundred to make the math easier. 361 can be rounded to 400 and 283 can be rounded to 300. When you add these rounded numbers together, 400 + 300 = 700, which is clearly greater than 500. Since rounding each number up only increases the sum, the actual sum of 361 + 283 must also be greater than 500.

This concept is based on the understanding that the rules of mathematics are universally valid, as addition is commutative (A+B=B+A).

The midpoint is (-4,1)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates and divide by 2

(-6+-2)/2 = -8/2 = -4

To find the y coordinate of the midpoint, add the y coordinates and divide by 2

(-4+6)/2 = 2/2 =1

The midpoint is (-4,1)

Answer:

The midpoint of the segment is at (-4,1)

Step-by-step explanation:

Since the midpoint of an line segment is the middle of the two x and y coordinates:

x-coords:

-6+-2 = -8

-8/2 = -4

y-coords

-4+6 = 2

2/2 = 1

The midpoint of the segment is at (-4,1)

The amount owed after 9 years on a $2000 loan compounded semiannually at an 18% interest rate is approximately $8599.63.

When we need to find the amount owed after 9 years on a $2000 loan compounded semiannually at an 18% interest rate, we use the formula for compound interest:

A = P (1 + r/n)^(nt)

Where:

A is the amount of money accumulated after n years, including interest.

P is the principal amount ($2000).

r is the annual interest rate (18% or 0.18).

n is the number of times the interest is compounded per year (2 for semiannual).

t is the time the money is invested for, in years (9 years).

Substituting the values into the formula, we have:

A = 2000 (1 + 0.18/2)^(2*9)

A = 2000 (1 + 0.09)^(18)

A = 2000 (1.09)^18

Calculating this expression gives us the amount owed after 9 years. Do not round any intermediate computations, and round your answer to the nearest cent.

The calculation is as follows:

A = $2000 * (1.09)^18

A ≈ $2000 * 4.299816955

A ≈ $8599.63

Therefore, the amount owed after 9 years would be approximately $8599.63.

Final answer:

The submarine will travel approximately 1532 feet horizontally as it dives down at an angle of depression of 40 degrees to a depth of 2000 feet, using the cosine trigonometric function to calculate this distance.

Explanation:

The student's question involves finding the horizontal distance a submarine will travel as it dives at a given angle of depression. When solving problems like this, we can use trigonometric functions, specifically the cosine function, because the horizontal distance is the adjacent side of a right-angled triangle, with the angle of depression being one of the angles, and the depth of the dive being the opposite side.

Now calculate the horizontal distance: x = 2000 * 0.766, which gives us x ≈ 1532 feet.

Therefore, the horizontal distance traveled by the submarine when it finished its dive is approximately 1532 feet.

Answer:

Step-by-step explanation:

You want the volume of a medicine capsule and the mass of active ingredient if the capsule is a cylinder 4 mm in diameter and 5.6 mm long, capped on either end by a hemisphere, and the active ingredient has a density of 0.7 mg/mm³.

The volume of a cylinder is given by ...

  V = πr²h

and the volume of a sphere is given by ...

  V = 4/3πr³

The two hemispheres have a total volume equal to that of a sphere, and the radii of the cylinder and sphere are the same. This means the volume of the capsule can be found as ...

  V = πr²h +4/3πr³

  V = πr²(h +4/3r)

The radius is half the diameter, so we have ...

  V = π(2 mm)²(5.6 mm +4/3(2 mm)) ≈ 103.882 mm³

The volume of the capsule is about 103.9 mm³.

Multiplying the volume by the density gives the mass of active ingredient:

  m = ρV

  m = (0.7 mg/mm³)·(103.882 mm³) ≈ 72.72 mg

There are about 72.7 mg of active medication in one capsule.

Answer:

  B) Circle F is shown. A line segment goes from one point to another point on the circle and goes through point F. It has a length of 20.

Step-by-step explanation:

A segment that goes through the center of the circle and that has its ends on the circle is a diameter. The radius is half the length of the diameter.

A chord through the center of circle F with a length of 20 units means circle F has a radius of 10 units.

Final answer:

Option B is the correct answer because it describes a line segment that passes through the center and is 20 units long, indicating it's a diameter; hence the radius is half of that, which is 10 units.

Explanation:

To determine which circle has a radius of 10 units, we need to recall that the radius is a straight line from the center of the circle to a point on its boundary. Two radii lined up end-to-end across a circle form a diameter. Therefore, a diameter is twice the length of the radius.

Option A describes a line segment of length 10, but we cannot confirm if it's a radius or a diameter without additional information.

Option B describes a line segment that goes through the center point F and is 20 units long, indicating it's a diameter. Since the diameter is twice the radius, a circle with a diameter of 20 units has a radius of 10 units.

Option C, like option A, cannot be confirmed without additional information about the line segment's relation to the center of the circle.

Option D also describes a line segment of 20 units, but again, without confirmation that it's a diameter, we cannot be sure.

Therefore, the correct answer is Option B, where the circle's diameter is explicitly mentioned to be 20 units, meaning the radius is 10 units.

The angles are 150°, 108°, 90°, and 12°.

In a literal sense, corresponding means pairwise angles. Like the right corner angles of two triangles etc. But usually, we take them as:

For two similar figures, the pair by pair similar angles of those two similar figures are called corresponding angles. They are of the same measurement.

Suppose for example, that 10 people choose city A as a destination.

To calculate its corresponding angle, we have to use the following proportion, 60 people represent the whole circle, is 360°, then 10 people are represented by:

France:

25/60 × 360 = 150°

Spain:

18/60 × 360 = 108°

Greece:
