Answer:

diameter [d]=15cm

radius [r]=7.5cm

slant height be l

and

height be h.

lateral surface area of cone =

πrl=477cm²

l=477/(3.1416*7.5)

l=20.244

now

h=\sqrt{20.2²-(7.5/2)²}=20cm

<u>height</u><u>=</u><u>2</u><u>0</u><u>c</u><u>m</u><u>.</u><u />

LSA of cone = πrl = 477cm²

L = 477/(3.1416 × 7.5)

L = 20.244

Height (h) = √{20.2²-(7.5/2)²}

h = 20cm

The formula M=log I/S determines the magnitude of an earthquake, where I is the intensity of the earthquake and S is the intensi
andriy [413]

Answer:

100

Step-by-step explanation:

M = log(I/S)

The intensity of the first earthquake:

8 = log(I₁/S)

10⁸ = I₁/S

I₁ = 10⁸ S

The intensity of the second earthquake:

6 = log(I₂/S)

10⁶ = I₂/S

I₂ = 10⁶ S

The ratio is:

I₁/I₂ = (10⁸ S) / (10⁶ S)

I₁/I₂ = 100

It is 100 times stronger.

Sheryl spends ​$17 every week on cigarettes and spends ​$24 a month on dry cleaning. On an annual​ basis, the money spent on cig
Rzqust [24]

the correct question is

Compute the total cost per year of the following pair of expenses. Then complete the sentence: On an annual basis, the first set of expenses is _% of the second set of expenses.Sheryl spends $17 every week on cigarettes and spends $24 a month on dry cleaning.


we know that

1 year is equal to 52 weeks

1 year is equal to 12 months

To calculate:

$17 * 52 = $884

$24 * 12 = $288

then

884/288 = 3.0694 * 100 = 306.94%

NEED ANSWERS QUICKLY! CORRECT ANSWER GETS BRAINLIEST
dolphi86 [110]

Answer/Step-by-step explanation:

Quotient is simply the ratio of the first numerator to the second numerator:

Let's \frac{x_1}{y}\;and\;\frac{x_2}{y} are two fractions in same terms.

Thus, \frac{x_1}{y}\div\frac{x_2}{y} {Divided by a fraction is equal to multiplied by its reciprocal}

=\frac{x_1}{y}\times\frac{y}{x_2}

Quotient is simply the quotient of their numerators.

Example could be:

\frac{2}{7}\div\frac{3}{7}

\frac{2}{7}\times\frac{7}3}

\frac{2}{3}

2 is first numerator and 3 is the second numerator.
