Answer:

Step-by-step explanation:

The area of a triangle is commonly described as one half times the base times the height. A better way to describe it though might be one half times the base times the length from the highest point to the base. A bit more of a mouthful but it helps get rid of confusion in cases like this.

So, the distance from the base to the highest point is 25 mm and the base itself is 11 mm. That 23 doesn't mean anything here and the 35 is the length of one of the sides, but not the base or the height, so it's not used. Anyway, we have the values we need.

(1/2)11 * 25 = 137.5

Mary bought these art supplies: 4 paint brushes @ $1.29 each, 6 dowel rods @ $1.49 each, a jar of paste @ $1.25, and 2 canvases

Answer:

Option (1) is correct

The amount she receives back from $40 is $12.65

Step-by-step explanation:

Given: Mary bought the art supplies.

4 paint brushes @ $1.29 each, 6 dowel rods @ $1.49 each, a jar of paste @ $1.25, and 2 canvases @ $6.00 each.

We have to find the change she get from $40.

We first find the total cost of the art supplies.

Since, she brought 4 paint brushes @ $1.29 each,

Thus, cost of 4 paint brush is 1.29 × 4 = $5.16

Also, 6 dowel rods @ $1.49 each,

Thus, cost of 6 dowel rods is 1.49 × 6 = $8.94

Thus, cost of 1 jar of paste is $1.25

and 2 canvases @ $6.00 each

Thus, cost of 2 canvases is $12.00

Thus, total cost of art supplies = 5.16 + 8.94 + 1.25 + 12 =$27.35

Thus, amount she receives back from $40 is $40 - $12.35 = $12.65

A cell phone company says that a fully charged battery lasts 14 hours. In reality, each battery behaves a little differently. Fo

gregori [183]

Answer:

The percentage is 50%

Step-by-step explanation:

From the question we are told that

The mean is $\mu = 14 \ hours$

The standard deviation is $\sigma = 1 \ hour$

Generally on the normal distribution curve the mean divides the curve into two. with the half to the left of the mean (50% to the left )representing the percentage of the batteries that will last less than 14 hours and the area under the curve to the right (50% to the right)representing the percentage of batteries that will last longer than mean (14 hours )

Hence the percentage of the cell phone batteries that will be expected to last longer than 14 hours is 50%
