One leg of a right triangle has a length of 7 m. The other side have lengths that are consecutive integers. Find these lengths

Darina [25.2K]

Answer:

6 and 5

Step-by-step explanation:

Consecutive means that it is continuous, and since the triangle largest side (7) has to be less than the additive of two other sides. Therefore 6 and 5. Hope this helps.

(H/6 )- (1)<br> Solve for H<br> Please help me

likoan [24]

All you need to do for this is remove the parenthese and your answer will be $\frac{H}{6} -1$ because that's the furthest it can be simplified.

The roof on Crystal’s house is formed by two congruent trapezoids and two congruent isosceles triangles. She wants to put new wo

NeTakaya

Answer:

the total number of shingles is 3060

Step-by-step explanation:

Please have a look at the attached photo.

We need to find the total are of the roof.

The are of the trapezoid is:

A = 1/2 (base 1 + base 2) height

= 1/2 (20+30)*15

= 375 $ft^{2}$

The are of the triangle:

A = 1/2*base*height

= 1/2(1.5*10)

= 7.5 $ft^{2}$

=> We need to find the total are of the roof is:

The are of the 2 trapezoids + The are of the 2 triangles

= 375 $ft^{2}$ *2 + 7.5 $ft^{2}$ *2

= 765 $ft^{2}$

Given in the question that, the shingles are 1 foot by 1 foot, but they overlap by 0.75 square foot so the usable area of the shingle is only 0.25 $ft^{2}$

So the total number of shingles is:

765 $ft^{2}$ / 0.25 $ft^{2}$

= 3060

2) Jose has a new job and earns a salary of $48,000. Victor has a new job and earns a salary of $59,000. Jose will receive a sal

leonid [27]

Answer:

y = b + kn

Step-by-step explanation:

In any given year, the salary of each will be given by the equation

y = b + kn where

y = Salary

b= Initial salary before increment

k= Increment

n= is the year in question

Thus, this can be proven by equating the salaries of both workers.

Jose's salary will be $48,000 + $2800n

Victor's salary will be $59000 + $1700n

Thus, to get the particular year, we equate both as

$48,000 + $2800n = $59000 + $1700n

$2800n -$1700n =$59,000 - $48,000

$1100n =$11000

Canceling the dollar signs throughout, we get

n = 11000/1100 = 10 years.

If you worked his out, you will get that in the 10th year, both salaries will be $76,000.

Thus, the equation is

y = b + kn

with the variables as explained above.
