Answer: Ethan spent 4 hours mowing lawns.


Step-by-step explanation:

Mowing pay rate: $6/hour.
Groceries pay rate: $7.50/hour.

Assume mowing hours = x.
Bagging groceries hours = y.

The difference in hours is 10:
y - x = 10    ---------(1)

Total earnings: $129, which means:
6x + 7.50y = 129    ---------(2)

From (1), y = x + 10.

Substitute into (2):
6x + 7.50(x + 10) = 129
6x + 7.50x + 75 = 129
13.50x + 75 = 129

Subtract 75:
13.50x = 54

Divide both sides by 13.50:
x = 4

Calculate y:
y = 4 + 10 = 14

Therefore, Ethan worked 4 hours mowing lawns.

Let x represent the hours Ethan spent bagging groceries. Then, hours spent mowing lawns equals x + 10. The equation to solve is:

6x + 7.50(x + 10) = 129

Solving this gives x = 4, meaning Ethan worked 14 hours mowing lawns.

lawyer [3979]

Answer:

The p-value for this test is 0.031. It should be interpreted as "There is a 96.9% likelihood that the actual average of soup sales at the new site exceeds 75 bowls it daily"

Step-by-step explanation:

The p-value"In hypothesis testing, the p-value, or probability value, represents the likelihood of obtaining test outcomes at least as extreme as the observed results, given that the null hypothesis holds true"

The bus routes in a city run on average every 15 minutes. The route times can vary by three minutes. Which absolute value equati
AnnZ [3868]

Response:

Max = 18\ mins

Min = 12\ mins

Step-by-step explanation:

Information given:

Time = 15\ mins

Variation = 3\ mins

Objective:

Calculate the maximum and minimum values

The max value is found as follows:

Max = Time + Variation

Max = 15\ mins + 3\ mins

Max = 18\ mins

The min value is identified as follows:

Min = Time - Variation

Min = 15\ mins - 3\ mins

Min = 12\ mins

Assume that the flask shown in the diagram can be modeled as a combination of a sphere and a cylinder. Based on this assumption,
Svet_ta [4296]

Answer:

Here’s the response provided

Step-by-step explanation:

Referring to the flask diagram, the diameter of the cylinder measures 1 inch and its height (h) is 3 inches. Thus, the radius of the cylinder (r) = diameter / 2 = 1/2 = 0.5 inch

The volume of the cylinder can be calculated as πr²h = π(0.5)² × 3 = 2.36 in³

As for the sphere, its diameter is 4.5 in. Hence, the radius of the sphere R = diameter / 2 = 4.5/2 = 2.25 in

The volume of the sphere is calculated as 4/3 (πR³) = 4/3 × π × 2.25³ = 47.71 in³

The total volume of the flask = Volume of the cylinder  + Volume of the sphere = 2.36 + 47.71 = 50.07 in³

<pWhen the cylinder and the sphere are expanded by a scale factor of 2, the height (h') of the cylinder becomes 3/2 = 1.5 inches and the radius (r') becomes 0.5/2 = 0.025 inches.

The new volume for the cylinder = πr'²h' = π(0.25)² × 1.5 = 0.29 in³

For the sphere, the new radius is R' = 2.25 / 2 = 1.125 in.

The new volume of the sphere = 4/3 (πR'³) = 4/3 × π × 1.125³ = 5.96 in³

Thus, the new volume of the flask = The new volume of the cylinder  + The new volume of the sphere = 0.29 + 5.96 = 6.25 in³

<pThe ratio of the new volume to the original volume = New Volume of the flask / Volume of the flask = 6.25 / 50.07 = 1/8 = 0.125<pThe resulting volume will thus be 0.125 times the original volume

2. Peter drew two rays, AC and AP with A as a common endpoint. Which of the following statements
PIT_PIT [3895]

The complete question reads:

Peter created two rays, AC and AP, sharing a common vertex at point A. Which of the following statements

might accurately describe Peter's drawing?

I. AC and AP are parallel.

II. PAC represents an angle.

III. AC and AP are at right angles.

A. I and II

B. II and III

C. I and III

D. I, II, and III

Answer:

Option B: II & III

Step-by-step explanation:

We know Peter has drawn rays AC and AP.

Since the point A is shared as the endpoint, it indicates an angular relationship at this common point.

This angle could potentially be 90°, suggesting that rays AC and AP may be perpendicular.

Thus, the valid statements that characterize his drawing are: II & III.
