ElenaW [278]2 years ago
5 0

Answer:

A

Step-by-step explanation:

the height a creates with half of the baseline (5) and a leg (10) a right-angled triangle, and we can use Pythagoras to calculate a.

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle, so in our case the 10 side).

10² = a² + 5²

100 = a² + 25

75 = a²

a = sqrt(75) = sqrt(3×25) = 5×sqrt(3)

Jayden received a $600 signing bonus when he accepted a job as an executive assistant. If he makes $26 an hour, which equation m
IrinaVladis [17]

Given, the signing bonus of Jayden = $600.

Jayden makes $26 in an hour.

Jayden works for x hours.

For 1 hour he makes = $26

So for x hours he will make = $(26)(x) = $(26x)

So the total pay of Jayden = The sum of the signing bonus and the total pay for x hours.

The total pay of Jayden = $(600+(26x))

Given, jayden's total pay = y dollars.

So we can write the equation as y=600+26x

we have got the required equation y= 26x +600

zaharov [31]

Answer:

  20

Step-by-step explanation:

In 12 years, the sum of their ages will be 24 more than it is now. The sum of their ages now is 61-24 = 37.

If Jennifer is 3 years older than Peter, we have ...

  j + (j -3) = 37

  2j = 40 . . . . . . add 3

  j = 20 . . . . . . . divide by 2

Jennifer is now 20 years old.

_____

Peter is now 17 years old. In 12 years, they will be 29 and 32, so their ages will sum to 61.
