marishachu [46]

Answer:

There are 178 more boys in Barlow school as compared to Willow school.

Step-by-step explanation:

We are given the following in the question:

Barlow school:

Total number of students = 873

Number of boys =

$=\dfrac{4}{9}\times 873 = 388$

Willow school:

Total number of students = 630

Number of girls =

$=\dfrac{2}{3}\times 630 = 420$

Number of boys =

Total number of students - total number of girls

$=630-420 = 210$

Thus, Barlow school has greater number of boys than Willow school.

Difference between the number of boys =

$=388-210\\=178$

Thus, there are 178 more boys in Barlow school as compared to Willow school.

A building with a cost of $1,800,000 has an estimated residual value of $125,000, has an estimated useful life of 40 years, and

nika2105 [10]

Answer:

$41,875

Extra

a. $17,250 [($780,000 – $90,000) ÷ 40]

b. $366,000 [$780,000 – ($17,250 × 24 yrs.)]

c. $29,600 [($366,000 – $70,000) ÷ 10 yrs.]

Step-by-step explanation:

Step 1: Determine the cost of the asset

$1,800,000$

Step 2: Subtract the estimated salvage value of the asset from the cost of the asset to get the total depreciable amount

$1,800,000 - 125,000$

Step 3: Determine the useful life of the asset

$40$

Step 4: Divide the sum of step (2) by the number arrived at in step (3) to get the annual depreciation amount

$$41,875$

How do you prove that a point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects?

konstantin123 [22]

Check the picture drawn

Consider the line segment AB,

let M be the midpoint of AB, so AM=MA

erect the perpendicular MT to AB from point M. Pick a point P on MT and join it to the points A and B

The triangles PMA and PMB are congruent from the Side Angle Side congruence postulate:

AM=MA, PM is common and m(PMA)=m(PMB)=90°, as MT is perpendicular to AB

so PA=PB

Lincoln Middle School plans to collect more than 2000 cans of food in a food drive. So far, 668 cans have been collected. Write

Schach [20]

Let x be the unknown number.

7x + 668 < 2000 => 7x plus 668 is less than 2000

where:
7x => x represents the number of cans to be collected in 7 days
668 is the number of cans already collected.
2000 is the target number of cans.

7x + 668 < 2000
 - 668 -668
7x < 1332
÷7 ÷7
x < 190.30
or
x < 190

To check:

7x + 668 < 2000
7(190) + 668 < 2000
1330 + 668 < 2000
1998 < 2000
