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?
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 :)

Jim and Krutika win some money and share it in the ratio 3:1. Jim gets £40 more than Krutika.
How much did they get altogether?
Step-by-step explanation:
let the amount that Krutika gets be x, therefore, gets him the amount that jim get will be x +40
therefore 3/1=x+40/x
hence 3x=x+40
therefore x=40/2
x=20
Step-by-step explanation:
let the amount that Krutika gets be x, therefore, gets him the amount that jim get will be x +40
therefore 3/1=x+40/x
hence 3x=x+40
therefore x=40/2
x=20

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

Answer:
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

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?
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

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
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
