Answer:

surface area of a cone = 132.935πft

Step-by-step explanation:

to find the surface area of a cone

given that

radius = 5ft

height of cone = 21ft

recall that the formulae for finding the surface area of a cone = πr( r + √ h² + r²)

so,

surface area of a cone = πr( r + √ h² + r²)

surface area of a cone = π x 5( 5 + √ 21² + 5²)

surface area of a cone = 5π ( 5 + √ 441 + 25)

surface area of a cone = 5π( 5 + 21.587)

surface area of a cone = 5π (26.587)

surface area of a cone = 132.935πft

If the sum is x, x+5

Step-by-step explanation:

The sum of the two numbers x+y = a, increased by 5, a+5.

The sum of two numbers increased by 5 to be determined.

The sum is defined as the addition of two or more values.

Here,
Let the two numbers be x and y.
their sum is x+y = a(let)
Now the sum is increased by 5.
=a+5

Thus, the sum of the two numbers x+y = a, increased by 5, a+5.

Answer:

Runner 1

Step-by-step explanation:

Runner 1's speed is the slope of the line = (20-0)/(2-0) = 10

Runner 2's speed is the slope of the line = 8.5 (the coefficient of t)

Runner 3's speed is slope = (36-18)/(4-2) = 9

The fastest pace, therefore is of runner 1, because 10>9 AND 10>8.5

The required time the student spends on studying is 9.5 hours. Option C is correct.

The association between two numerical variables measured for the same individuals is displayed in a scatterplot. One variable's values are displayed on the horizontal axis, and the other variable's values are displayed on the vertical axis.

here,

Given the regression line,
y = 3.1 x + 40.5.

Put y = 70
70 = 3.1x + 40.5

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

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.

Answer:

0.0083

Step-by-step explanation:

Answer: A = 2500 (1.035)^n

A= $ 4,974.47

Step-by-step explanation:

A=P(1+r)^n

A= Amount

P= Principal

R= rate

N= # of years

A= 2500(1.035)^n

N=20

2500(1.035)^20

A= 4,974.47

The equation describing the relationship between the number of cinema sites and years past 2000 is y = -220x + 6700. To predict the number of cinema sites in 2009, substitute x = 9 into the equation, resulting in a predicted value of 4720.

To write an equation describing the relationship between the number of cinema sites and years past 2000, we can use the slope-intercept form of a linear equation, which is y = mx + b. In this case, y represents the number of cinema sites and x represents the years past 2000.

The slope (m) can be found using the formula (change in y)/(change in x), and the y-intercept (b) can be found by substituting one set of ordered pairs into the equation.

From 2000 to 2004, the change in years past 2000 is 4, and the change in the number of cinema sites is -880. Therefore, the slope (m) is -880/4 = -220.

We can substitute the ordered pair (0, 6700) into the equation to find the y-intercept (b).

So, the equation describing the relationship is y = -220x + 6700, where y is the number of cinema sites and x is the years past 2000.

To predict the number of cinema sites in 2009, we substitute x = 9 (since 2009 is 9 years past 2000) into the equation:

y = -220(9) + 6700

y = -1980 + 6700

y = 4720.

Therefore, the predicted number of cinema sites in 2009 is 4720.

Step-by-step explanation: Because if you had a zero on a number line you would subtract 5 from the left and that would give you negative 5

We are given y.

-4x - 8 = 24

~Add 8 to both sides

-4x - 8 + 8 = 24 + 8

~Simplify

-4x = 32

~Divide -4 to both sides

-4x/-4 = 32/-4

~Simplify

x = -8

Step-by-step explanation:

square root of 36 is 6 ^w^

u = 6

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.
