Curved surface of a cone of slant height 20 cm and base radius 14 cm is ____. * 1 point 280 sq.cm 2080 sq.cm 1496 sq.cm 880 sq.cm

Answers

Answer:

880 cm²

Step-by-step explanation:

Given that :

Curved surface area of a cone : πrl

r = base Radius = 14 cm

l = slant height = 20 cm

Hence,

Curved surface area = π * 14 * 20

Curvwd surface are = π * 14 * 20

Curved surface area = 879.64594 cm²

Curved surface area = 880 cm²

In 2011 Tufts University had 17,000 applicants. Each year the number of applicants increased 11% from the previous year.

How many applicants would you expect Tufts University to have in 2013? Round to the nearest whole

Answers

Explanation: it’s up by 2 years each being 11% so just multiply that by 2 and just do
17,000 x 22% which is 17,000 x 0.22 = 3,740
So 17,000 + 3,740 = 20,740

First two (S = 9.20 K = 10.15)

Step-by-step explanation:

Hours = x

Money Earned (AED) = y

Shamael

y = 9.2x

AED = 9.2(hours)

$9.20 an hour

Kamla

y = kx

([tex]x_{1} ,y_{1}[/tex]) = (5, 50.75)

([tex]x_{2}, y_{2}[/tex]) = (4, 40.60)

k = [tex]\frac{y_{1}-y_{2}}{x_{1}-x_{2}}[/tex] = [tex]\frac{50.75-40.60}{5-4}[/tex] = [tex]\frac{10.15}{1}[/tex] = 10.15

AED = 10.15(hours)

$10.15 an hour

Maura is going to hire a makeup artist for a fashion show and is comparing prices. Evelyn charges $19 as a booking fee and an additional $89 per hour. Brenda charges $87 per hour, plus a booking fee of $21. Depending on the length of the show, the cost could end up being the same for either artist. How long would the show be? What would the cost be?

Answers

Step-by-step explanation:

Evelyn: Y=89x + 19

Brenda: Y=87x + 21

Punch in numbers for X until you get the same for both. Remember that X is hours and Y is total. the numbers with no letters is the fixed booking amount. cheers. Good luck :)

The Parker Solar Probe is supposed to reach a top speed of 430,000 miles per hour. If it
were to fly at this speed for 43,800 hours (5 years), how many miles would it travel?

Answers

1.88*10^10 miles

Step-by-step explanation:

(430,000m/h)*(24 hours/ 1 day)*(365 days/ 1 year)*(5years)

Everything but miles cancels out,

430,000*(24*365*5) = 18,834,000,000miles

Or, 18.8 billion miles

Or, 1.88*10^(10) miles

Answers

Answer:

it's the second choice (3=3)

Answer:

y = - x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (3, 1)

m = [tex]\frac{1-3}{3-1}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 , then

y = - x + c ← is the partial equation

To find c substitute (1, 3 ) into the partial equation

3 = - 1 + c ⇒ c = 3 + 1 = 4

y = - x + 4 ← equation of line
