Step-by-step explanation:

square root of 36 is 6 ^w^

u = 6

Given:

a) Area = 121 ft²

b) Area = 81 yd²

To find:

The side length of each square

Solution:

a) Area = 121 ft²

Area of the square = s²

⇒ s² = 121

Taking square root on both sides.

[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 121}[/tex]

[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 11^2}[/tex]

Square root and squares get canceled.

⇒ s = 11

The length of each side of the square is 11 ft.

b) Area = 81 yd²

Area of the square = s²

⇒ s² = 81

Taking square root on both sides.

[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 81}[/tex]

[tex]\Rightarrow \sqrt{s^2} = \sqrt{ 9^2}[/tex]

Square root and squares get canceled.

⇒ s = 9

The length of each side of the square is 9 yd.

Answer:

-12

Step-by-step explanation:

a positive times a negative is a negative

Uisng the appropriate arithmetic operation, the value of 4y when y = - 3 is - 12.

To obtain the value of 4y, we substitute, the value of y into the equation thus :

4(-3) = 4 × - 3

4(-3) = - 12

Hence, the value of 4y = - 12

To find the air pressure of a thunderstorm, the given wind velocity is substituted into the function and the equation is solved for the air pressure in millibars.

To find the air pressure of a thunderstorm where the wind velocity is 49.3 meters per second, we need to substitute this given wind velocity into the given function and solve for p.

https://brainly.com/question/13624217

#SPJ12

To calculate the air pressure during a thunderstorm with a wind speed of 49.3 m/s, use the mathematical function provided. Solve for 'p' by setting the function equal to given wind speed, isolating 'p', and calculating thereafter.

The student's question pertains to finding an unknown in the function v(p) = 5.7 √998 - p, given that the wind velocity is 49.3 m/s. The expression given is for wind velocity in a storm, based on changing air pressure. To answer this, we need to solve the equation for 'p'.

1. First, we set the equation equal to 49.3: 49.3 = 5.7 √998 - p

2. Then we isolate the square root term by dividing by 5.7: (49.3/5.7) = √998 - p

3. After that, we square both sides to eliminate the square root: (49.3/5.7)^2 = 998 - p

4. We then isolate 'p' by subtracting the result from 998: p = 998 - (49.3/5.7)^2

Doing the calculations will give the approximate value of 'p', which is the air pressure in millibars for a thunderstorm with a wind velocity of 49.3 m/s.

Final answer:

The correct simplified form is \(\frac{1}{r^7} + \frac{1}{s^{12}}\), with each term representing the reciprocal of the base raised to a positive exponent and kept as separate terms.

Explanation:

The simplified form of r-7 + s-12 is \(\frac{1}{r^7} + \frac{1}{s^{12}}\). The negative exponents indicate that each term is the reciprocal of the base raised to the positive exponent. So, r-7 becomes \(\frac{1}{r^7}\) and s-12 becomes \(\frac{1}{s^{12}}\). Since these are two separate terms, they are not combined together into a single fraction.

Answer:

Step-by-step explanation:

First, calculate the volume of water needed to fill the pond one-quarter of the way up, then multiply that by the cost per cubic foot to find the total cost, which is approximately $2297.29.

The subject of this question is Mathematics, more specifically, it involves the use of geometry and algebra. The question is asking about the cost of filling a cylindrical pond one-quarter of the way up with water, given the dimensions of the pond and the price of water per cubic foot.

To answer this question, we first need to determine the volume of water needed. Since the pond is cylindrical, we use the formula for the volume of a cylinder: V = πr²h, where r is the radius and h is the height. The diameter is given as 30 feet, so the radius is 15 feet (half the diameter), and we're filling to a depth of 1.25 feet (one-quarter of the 5-foot depth). This gives us a volume of approximately 706.86 cubic feet.

We then multiply this volume by the price of water. At $3.25 per cubic foot, that's a total cost of about $2297.29. So, you would need to spend approximately $2297.29 to fill the pond one-quarter of the way up with water.

Answer:

-63/16

Step-by-step explanation:

csc x = 5/3

sin x = 3/5

So x is the angle in a 3-4-5 triangle, opposite of the 3.

cos y = 5/13

So y is the angle in a 5-12-13 triangle, opposite of the 12.

tan(x + y) = (tan x + tan y) / (1 − tan x tan y)

tan(x + y) = (3/4 + 12/5) / (1 − (3/4)(12/5))

tan(x + y) = (3/4 + 12/5) / (1 − 9/5)

tan(x + y) = (15 + 48) / (20 − 36)

tan(x + y) = -63/16

Radius of a sphere with a volume of 26,244π inches³ is 27 inches.

Volume of a sphere, V = (4/3)πr³.

Given the volume of 26,244π inches³,

(4/3)πr³ = 26,244π

The radius of sphere (r) =

r³ = (26,244π)/(4/3)π

r³ = 26,244 × (3/4)

r³ = 19,683

r = ∛19,683

r = 27 inches

The radius of the sphere is 27 inches.

The formula for the volume (V) of a sphere with radius (r) is given by:

[tex]\[ V = \frac{4}{3} \pi r^3 \]Given that the volume (\( V \)) of the sphere is \( 26,244\pi \) cubic inches, we can set up the equation:\[ 26,244\pi = \frac{4}{3} \pi r^3 \]To solve for \( r \), we first divide both sides by \( \frac{4}{3} \pi \):\[ r^3 = \frac{26,244\pi \times \frac{3}{4}}{\pi} \]\[ r^3 = 19,683 \][/tex]

Taking the cube root of both sides:

[tex]\[ r = \sqrt[3]{19,683} \]\[ r \approx 27 \][/tex]

Therefore, the radius of the sphere is 27 inches.
