A City Has Cone Shaped Buildings For Storing Salt And Sand For Icy Roads. Each Building Has A Radius

Answers

Answer 1

Answer:

Radius=50 ftπ=3.14Height=30 ftVolume=?

We know that,

[tex]\star \: \: \purple{Volume_{(cone)} =\pi {r}^{2} \frac{h}{3} }[/tex]

[tex]\star \: \: \purple{Volume_{(cone)} =3.14 \times {(50)}^{2} \times \: \cancel\frac{30}{3} \: }[/tex]

[tex]\star \: \: \purple{Volume_{(cone)} = 3.14 \times (50 \times 50) \times 10} [/tex]

[tex]\star \: \: \purple{Volume_{(cone)} =3.14 \times 2500 \times 10 }[/tex]

[tex]\star \: \: \purple{Volume_{(cone)} =78500 }[/tex]

Thus,the third option is correct.

So the point of A from the origin is 12ft to the right and 24ft up, or better still it’s at the point (4,8). Since the scale doubles to 6 ft, the coordinate will half. So 12 ft to the right is reflected over 2 to the right and 24ft up goes to 4 squares up because we divide it by 6ft for the scale. Doing this and plotting the point you’d get (2,4) which is half the original coordinate of A as I said it will be.

For a recent job, a plumber earned $28/hr, and the plumber’s apprentice earned $15/hr. The plumber worked 3 hours more than the apprentice. If together they were $213, how much did he esrn

Answers

Answer: (with explanation) (ANSWER AT THE BOTTOM)

et P = number of hours that the plumber worked.

let H = number of hours that the helper worked.

since the plumber worked 3 more hours than the helper, the equation for hours worked is

P = H + 3

-----

since the plumber earned 28 dollars per hour and the helper earned 15 dollars per hour, the equation for amount of money each made is the number of hours each worked times the dollars per hour each earned.

this equation is

(28*P) + (15*H) = 213 dollars

-----

both get the same answer.

-----

-----

substitute for P in the money equation since P is the same as H + 3.

equation becomes

(28*(H+3)) + (15*H) = 213

solve for H.

28*H + 28*3 + 15*H = 213

43*H + 84 = 213

43*H = 129

H = 3

-----

if H = 3, then P = 6 because P = H + 3.

-----

6*28 + 3*15 = 213 so your answer is

Plumber works 6 hoursHelper works 3 hours.

now to find the amount each earn by themselves, we just have to multiply by 6 or 3 by their hourly earning.

let's do the Plumber first

28x6=168

now the helper

15x3=45

---------

now to check if that was the right answer, let's add them up...

168+45=213

so, our answer is right.

-----------------

The plumber worked for 6 hours and earned $168 and the helper worked for 3 hours and earned $45 dollars. In total, they earned $213.

5000 · 4.32

h(x)= 21,600

Answer:

$6802.44

Step-by-step explanation:

We will replace x with 4.

h(4) = 5000 · (1.08)^4

Use a calculator from here if you don't want stress.

1.08 x 1.08 x 1.08 x 1.08 = 1.36048896

1.36048896 x 5000 = 6802.4448

Since we are looking at the cost, we will approximate to the nearest hundredth.

6802.4448 ≈ 6802.44

The cost is $6802.44.

Find

(ii) BCE​

Answers

Answer:

(i) 88°

(ii) 23°

Step-by-step explanation:

See the picture below.

The numbers added in red are the angle measures. The numbers added in black are the order in which each angle measure was written.

ABCD is a rhombus, so all sides are congruent.

Triangle BCD is isosceles with sides DC and BC congruent, so <DBC is congruent to <BDC. From the sum of the measures of the angles of a triangle, we get m<DCB. Opposite angles of a rhombus are congruent, so m<A = m<DCB. From the sum of the measures of the angles of a triangle and from isosceles triangle ADB we get m<ADB and m<ABD. From m<DBC and supplementary angles, we get m<CBE. From isosceles triangle BCE, we get m<BCE.

Step-by-step explanation:

Using the variable definitions shown, the two given relations are ...

  11 +x +y = 45 . . . . . . 45 total orders

  x = y -2 . . . . . . . . . . 2 fewer medium orders than large

__

Using the second equation, we can substitute for x in the first equation to solve this system:

  11 +(y -2) +y = 45

  2y = 36 . . . . . . . . . . collect terms and subtract 9 from both sides

  y = 18 . . . . . . . . . . . divide both sides by 2

  x = 18 -2 = 16 . . . . use the second equation to find the value of x

At what point on the curve y = 9 + 2ex − 5x is the tangent line parallel to the line 5x − y = 8?

(x, y) = ?

Answers

Answer:

[tex](\ln(5), 19-5\ln(5))[/tex]

Step-by-step explanation:

The line can be represented as y=5x-8, so the slope of the line is 5.

The derivative of the curve is:

[tex]\frac{d}{dx} [9+2e^x-5x]\\=\frac{d}{dx} [9]+\frac{d}{dx} [2e^x]-\frac{d}{dx} [5x]\\=2e^x-5\\[/tex]

We need to set that equal to 5 to find the x coordinate of our desired point

[tex]2e^x-5=5\\2e^x=10\\e^x=5\\x=\ln(5)[/tex]

Now, just plug in x in the curve to solve for y:

[tex]9+2e^{\ln(5) } -5\ln(5) = y\\9+10-5\ln(5)=y\\19-5\ln(5)=y[/tex]

Line 5x y = 8 has a slope of 5. This means that the tangent line that runs parallel to this line must also have a slope of 5.

To solve this equation

dy/dx = 2ex 5 is the derivative of the function y = 9 + 2ex 5x. Consequently, 2ex 5 is equal to the slope of the tangent line at any location.

When we set the slope of the tangent line to 5, we obtain:

2ex − 5 = 5

2ex = 10

e^x = 5

Taking the natural logarithm of both sides, we get:

ln(e^x) = ln(5)

x = ln(5)

Therefore, ln(5) is the x-coordinate of the crossing point.

We can enter this value of x into the original function to determine the y-coordinate:

y = 9 + 2e^(ln(5)) − 5(ln(5))

y = 9 + 10 − 5ln(5)

y = 15 − 5ln(5)

As a result, the intersection is at (ln(5), 15 5ln(5)).

To sum up, (ln(5), 15 5ln(5)) is the point on the curve y = 9 + 2ex 5x where the tangent line is parallel to the line 5x y = 8.

Calculation of number of races

The number of sprinters = 271

The number of sprinters per race= 7

The area to be covered for each race = 200m

For every race covered, a champion is selected and the rest is eliminated.
