Answer:

180000 m/s

Step-by-step explanation:

The frequency of the wave is 900 Hz.

The wavelength of the wave is 200 m.

The speed of a wave is given as the product of wavelength and frequency. That is:

v = λf

where λ = wavelength

f = frequency

The speed of the wave is therefore:

v = 200 * 900 = 180000 m/s

The speed of the wave is 180000 m/s.

Answer:

AC = 10sin 40°

Step-by-step explanation:

From the diagram attached, using terms in trigonometric ratio, AC is the opposite side, BC is the adjacent side and AB is the hypotenuse.

Thus, since we want to find AC;

We know that in trigonometric ratios; opposite/hypotenuse = sin θ

In the diagram, θ = 40° and AB = 10

Thus,

AC/10 = sin 40°

Multiply both sides by 10 to get;

AC = 10sin 40°

Answer:

The sandcastle B has the greatest volume

Step-by-step explanation:

The volume of a pyramid is given by the following formula:

V = (1/3) * A * h

Where A is the base area and h is the height.

Now we can calculate the volume of both pyramids:

V1 = (1/3) * 30 * 6 = 60 in3

V2 = (1/3) * 24 * 8 = 64 in3

So the volume of the pyramid B is bigger than the volume of the pyramid A.

To solve the given polynomial addition and subtraction question, combine like terms. The z4 terms combined are -7z4 and the z2 terms are 5z2, resulting in the simplified expression 5z2 - 7z4.

To add or subtract the polynomials 7z2 − 2z4 − 2z2 − 5z4, you'll want to combine like terms. Like terms are terms that have the same variables raised to the same power.

Here, z2 and z4 are like terms, so you can combine them separately.

Starting with the z4 terms:
-2z4 and -5z4 combine to give you -7z4. They both have the same variable z raised to the fourth power, so you just add the coefficients, keeping the exponent the same.

Then, combine the z2 terms:

7z2 and -2z2 combine to give you 5z2.

Similarly, these terms have the same variable z raised to the second power.

Now, putting it all together, you get:

5z2 − 7z4

This is the simplified version of the polynomial after combining like terms.

The circumference of a circle can be calculated using the formula C = 2πr, where C is the circumference and r is the radius.

The circumference of a circle can be found using the formula C = 2πr, where C represents the circumference and r is the radius of the circle.

For example, if the radius of the circle is 5cm, the circumference would be C = 2π(5) = 10π cm. It is important to note that the circumference is always given in terms of π, which represents the mathematical constant.

Therefore, the circumference of a circle can be calculated by multiplying the radius by 2π.

Answer:

Part A: 32 square yards per gallon

Part B: 13 square feet per gallon difference

Step-by-step explanation:

Part A:

To find how many square yards each gallon covers, you have to divide 42 2/3 by 1 1/3, which equals 32. That means each gallon of paint covers 32 square yards.

Part B:

First, you have to convert how much Angela covered in square yards to square feet. Since one square yard is equal to 9 square feet, we have to multiply 32 by 9, which equals 288. To find the difference, you have to subtract 288 - 275, which equals 13.

Final answer:

Angela's rate of paint coverage in square yards per gallon is 32, and the difference in square feet per gallon between Angela’s rate and the average rate on the paint label is 13 square feet per gallon.

Explanation:

Part A: Calculating Paint Coverage

To find Angela’s rate of paint coverage in square yards per gallon, we would divide the total area painted by the amount of paint used. We have 42 2/3 square yards painted using 1 1/3 gallons of paint. First, it's easier to work with improper fractions, so we convert 42 2/3 to (126/3 + 2/3) = 128/3 square yards, and 1 1/3 to (3/3 + 1/3) = 4/3 gallons. Now, we calculate the rate by dividing the square yards by the gallons:

Rate = ​(128/3) / (4/3) = (128/3) × (3/4) = 128/4 = 32 square yards per gallon.

Part B: Difference in Square Feet per Gallon

To find the difference in square feet per gallon, we need to compare Angela's rate to the average rate given on the label. Angela's rate is 32 square yards per gallon, and there are 9 square feet in a square yard. So, Angela's rate in square feet would be 32 × 9 = 288 square feet per gallon. The label states an average coverage rate of 275 square feet per gallon. Thus, the difference is:

Difference = Angela’s rate - Label’s rate = 288 - 275 = 13 square feet per gallon difference.

The statement which best describes the situation correctly is that the golf ball is on the ground at 0 and 6 seconds.

Given that:

Sharon hits a golf ball off the ground.

The function h represents the height of the golf ball, in feet, t seconds after it is hit.

h(t) = -16(t - 3)² + 144, which is a quadratic function.

Since the options contain the time when the ball hits the ground, it is required to find the time when the ball hits the ground.

When the ball is on the ground, the height is 0.

So, h(t) = 0

-16(t - 3)² + 144 = 0

-16(t - 3)² = -144

Divide both sides by -16.

(t - 3)² = 9

Take the square root on both sides.

t - 3 = ±√9

t - 3 = ±3

So, t = 3 + 3 and t = -3 + 3

So, t = 6 and t = 0

Hence, the ball hits the ground when t = 0 and t = 6, which is option B.

The diameter of a sphere is 0.926 inch. It is required to find the volume of the sphere. The formula used to find the volume of sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Since, r is radius, r = d/2 = 0.463 inch

Area of a rectangle is length x width.

Let the width = x

The length would be x +7. ( 7 inches longer than the width)

Area = 20

Set up the formula:

20 = x * x+7

Simplify the right side:

20 = x^2 + 7x

Subtract 29 from both sides:

X^2 + 7x -20 = 0

Solve using the quadratic equation

X = -b + sqrt(b^2 -4ac) / 2a

X = -7 + sqrt(7^2-4(1)(-20) / 2(1) (exact answer)

X = 2.178908 ( as a decimal)

The width is 2.178907 inches (round as needed)

The length would be 9.178907 inches ( round as needed.)

Depending on how you round, when you multiply them together you get approximately 20 square inches.

Step-by-step explanation:

Step 1:  Find the dimensions

l = 7 + w

Area = 20

Find width

[tex]A = l * w[/tex]

[tex]20 = (7 + w)(w)[/tex]

[tex]20 - 20 = 7w + w^2 - 20[/tex]

[tex]w^2 + 7w - 20 = 0[/tex]

[tex]w=\frac{-(7)\pm\sqrt{(7)^2-5(1)(-20)}}{2(1)}[/tex]
