50 · (3÷4) = 37.5

Because each ribbon requires 3/4 of a yard its just 50 3/4

Nifal earned 9$ for washing two cars .He recived $1 more for the second car.How much was he paid for washing each car?Which two
Sveta_85 [38]

Answer:

Nifal received $ 4 for washing the first car.

Nifal received $ 5 for washing the second car.

4 and 5 have a sum of 9.

Step-by-step explanation:

The problem can be rewritten as follows: Find the sum of two consecutive entire numbers equal to 9. That is:

x + y = 9

y = x+1

Then, by eliminating y:

x + (x+1) = 9

2\cdot x + 1 = 9

Now, let is clear x:

2\cdot x = 8

x = 4

Nifal received $ 4 for washing the first car.

The earning for the second car is: (x = 4)

y = x +1

y = 4 + 1

y = 5

Nifal received $ 5 for washing the second car.

4 and 5 have a sum of 9.

A spherical hot air balloon has a diameter of 55 feet when the balloon is inflated the radius increases at a rate of 1.5 feet pe
Nuetrik [128]

Answer: 46.90mins

Step-by-step explanation:

The given data:

The diameter of the balloon = 55 feet

The rate of increase of the radius of the balloon when inflated = 1.5 feet/min.

Solution:

dr/dt = 1.5 feet per minute = 1.5 ft/min

V = 4/3·π·r³

The maximum volume of the balloon

= 4/3 × 3.14 × 55³

= 696556.67 ft³

When the volume 2/3 the maximum volume

= 2/3 × 696556.67 ft³

= 464371.11 ft³

The radius, r₂ at the point is

= 4/3·π·r₂³

= 464371.11 ft³

r₂³ = 464371.11 ft³ × 3/4

= 348278.33 ft³

348278.333333

r₂ = ∛(348278.33 ft³) ≈ 70.36 ft

The time for the radius to increase to the above length = Length/(Rate of increase of length of the radius)

The time for the radius to increase to the

above length

Time taken for the radius to increase the length.

= is 70.369 ft/(1.5 ft/min)

= 46.90 minutes

46.90mins is the time taken to inflate the balloon.

HELP PLEASE!! WILL GIVE BRAINLIEST!!!
beks73 [17]

Answer:

Slope = 2 Y-Intercept = (0, 3)

Step-by-step explanation:

Slope : \frac{Rise}{Run}  which is \frac{y2 - y1}{x2 - x1} from two points: point1 (x1 , y1) and point2 (x2, y2).

For the purpose of getting the slope I will be using point (0, 3) as point 1

and point (-3, -3) as point 2.

If you plug in 0 as x1, 3 as y2, -3 for x2, and -3 for y2:

\frac{-3 - 3}{-3 - 0} = \frac{-6}{-3} = 2

Y-Intercept: The y intercept is the point where the line is touching the y axis. Which in this graph, there is only point (0,3).
