Mr. Littles is building a triangular sandbox using three boards. He already has two boards that measure 9 feet and 12 feet. Sele

Answer:

How much is the rent? And how many clothes does she want to buy?

Step-by-step explanation:

The equivalent ratio is 3/4.

Mel descends 50-35=15 feet in 5-2=3 seconds. Thus, her descent rate is 15/3=5 ft/sec.
Victor descends 60-50=10 feet in 4-1=3 seconds. Hence, his descent rate is 10/3=3⅓ ft/sec. Mel is faster, traveling at 5 ft/sec.

Response:

The average of the 10 sales figures for store A is $40,000.

Detailed explanation:

Provided;

yˆ= −3,000 + 1.2x...................... (1)

Where;

x = daily sales amounts at store A or the average of the 10 sales amounts for store A =?

yˆ = daily sales amounts at store B or the average of the 10 sales amounts for store B = $45,000

Substituting y = 45,000 into equation (1) and solving for x, yields:

45,000 = −3,000 + 1.2x

45,000 + 3,000 = 1.2x

48,000 = 1.2x

x = 48,000 / 1.2

x = 40,000

Consequently, the mean of the 10 sales figures for store A is $40,000.

The average speed for his entire journey from York to Blackpool is about 61.41 km/h.

Here’s a breakdown of how we arrive at this:

The distance he travelled from York to Leeds is 45 km,

and the speed during that section was 54 km/h.

Therefore, the time taken to travel from York to Leeds is 45/54 hours (since Time = Distance/Speed).

Next, the distance from Leeds to Blackpool is 42 km,

and the time for that leg of the journey is 35 minutes, which is 35/60 hours.

This leads to the total duration for his trip as

hours.

The cumulative distance covered equals 45 + 42 = 87 km.

Thus, his average speed is calculated as:
