She uses $31.99 to pay for the items.

2(12.36) + 1.98 + 3.49
= 24.72 + 5.47
= 30.19 (cost of all items)

$30.19 + 0.80 = 31.99

A punch bowl contained 2 liters of ginger ale, 1 liter of orange juice, and 1 liter of cranberry juice. Select all of the statem

loris [4]

Answer:

The ratio of juices to ginger ale is 2 to 2

The ratio of orange juice to the cranberry juice is 1 to 1

Step-by-step explanation:

Ginger ale = 2 liters

Orange juice = 1 liter

Cranberry juice = 1 liter

Total ratio = 2 + 1 + 1 = 4

The ratio of ginger ale to the entire punch bowl is 1 to 4.

Ginger ale : entire punch bowl

= 2 : 4

= 1 : 2

Not true

The ratio of orange juice to ginger ale is 2 to 1.

Orange juice : ginger ale = 1 : 2

Not true

The ratio of juices to ginger ale is 2 to 2.

juices : ginger ale = orange juice + cranberry juice : ginger ale

= 1 + 1 : 2

= 2 : 2

True

The ratio of the entire punch bowl to the juices is 2 to 4.

Entire punch bowl : juices 4 : 2

Not true

The ratio of orange juice to the cranberry juice is 1 to 1.

Orange juice : cranberry juice = 1 : 1

True

Write the integral in one variable to find the volume of the solid obtained by rotating the first-quadrant region bounded by y =

Dovator [93]

Answer:

V = π ∫₀² (y² − 8y + 6√(2y)) dy

V = π ∫₀² (6x − 5x² + x³) dx

Step-by-step explanation:

y₁ = 0.5x²

y₂ = x

First, find the intersections of the curves.

0.5x² = x

x² = 2x

x² − 2x = 0

x (x − 2) = 0

x = 0 or x = 2

So the points of intersection are (0, 0) and (2, 2).

When we revolve this region about the line x = 3, we get a hollow shape that looks like an upside-down funnel, or a volcano.

One option is to use washer method to find the volume, by cutting a thin horizontal slice of thickness dy, inner radius 3−x₁ = 3−√(2y), and outer radius of 3−x₂ = 3−y.

V = ∫₀² π [(3−y)² − (3−√(2y))²] dy

V = ∫₀² π (9 − 6y + y² − 9 + 6√(2y) − 2y) dy

V = π ∫₀² (y² − 8y + 6√(2y)) dy

Another option is to use shell method to find the volume, by cutting a thin vertical slice of thickness dx, radius 3−x, and height y₂−y₁ = x−0.5x².

V = ∫₀² 2π (3 − x) (x − 0.5x²) dx

V = ∫₀² 2π (3x − 1.5x² − x² + 0.5x³) dx

V = ∫₀² 2π (3x − 2.5x² + 0.5x³) dx

V = π ∫₀² (6x − 5x² + x³) dx

The second option is arguably easier to evaluate, but either one will get you the same answer (V = 8π/3).

Find the slope (-2,-4) (-5,5)

diamong [38]

Answer:

Your answer would be Slope m = -3

Step-by-step explanation:

Step 1: Graph the points on a coordinate plane( refer to image!)

Whenever your trying to find a slope of 2 order pairs, remember this

m = rise/run. ( Slope = rise over run.) = Δy/Δx

Now we solve:

M = rise/run = Δy/Δx

M = y2 - y1/x2-x1

M = 5 - (-4) / -5-(-2)

So we get M = 9/-3 and 9 divided by -3 is -3

So, the slope of (-2,-4) and (-5,5) is -3.

Answer:

◻️B. The value of the mode is the least value of the data.

Step-by-step explanation:

The mode is the data value that appears most often

5,7,9,5,18,6,8,5

Arranging the data from smallest to largest

5,5,5,6,7,8,9,18

The number that appears most often is 5

This is the smallest value of the data
