The number of hours Hamal works is represented as x.

Since we need to find the amount Hamal is earning per hour (or in an hour), we replace x as 1 (for 1 hour)

Now, we get the equation : y = 10 x 1 + 50.

Since y represents the amount of money he earns, we need to find y when x = 1, or the equation above.
-> y = 60.

Therefore, Hamal earns 60 (dollars?) per hour.

The number of hours of rain is 34.

The depth of the creek before the rain was 3 feet. There was a flood last month. The depth of the creek rose to 20 feet after the flood. The weather man said that it rained for 0.5 feet every hour.

The rise in the depth of the creek is the difference between the final and initial depths.

D = 20 - 3 = 17 feet

The number of hours for which it rained is the result of the division of the rise in the depth by the rate of rain.

N = 17/0.5

N = 34 hours

Since the series is an Arithmetic progression, the difference between the consecutive terms is constant,

Therefore,

(2x+8) - (x+4) = 12 - (2x+8)

⇒ 2x + 8 - x - 4 = 12 - 2x - 8

⇒x + 4 = 4 - 2x

The formula for calculating standard deviation of a sample is expressed as

Standard deviation = √Σ(x - mean)^2/(n - 1)

where

n = the number of samples = 5

Mean = (17 + 20 + 44 + 39 + 40)/5

Mean = 32

Σ(x - mean)^2 = (17 - 32)^2 + (20 - 32)^2 + (44 - 32)^2 + (39 - 32)^2 + (40 - 32)^2 = 626

n - 1 = 5 - 1 = 4

Standard deviation = √(626/4)

Standard deviation = 12.51

The equation of a circle with its center at the origin and passes through the point (5,0):   x2+y2=25

the equation of a circle of with the center (2,3) and containing the point (3,2): x2+y2=2

Origin is referred to as the first point or the starting point from which we begin our calculations or measurements in mathematics, particularly in the subject of coordinate geometry. The 0 on a ruler is the point at which we begin taking measurements; as a result, it is referred regarded as the scale's origin.

(x-h)^2+(y-k)^2=r2

                          is the equation for a circle with center (h,k) and radius (r).

This yields the more well-known equation

x2+y2=r2

             for a circle centered at the origin.

Since we are aware that the circle's center is at its origin, i.e.

This fact, together with the circle's intersection point (5,0), can be used to determine the radius. The distance formula is used for this.

r=√(x2−x1)^2+(y2−y1)^2

In light of (0,0) and (5,0):

r=√(5−0)^2+(0−0)^2

=√25+0

√25=5

⇒ r=5

Therefore, x^2+y^2=(5)^2

                   x2+y2=25 is the equation for the circle.

(x-h)^2+(y-k)^2=r2 is the equation for a circle with center (h,k) and radius (r).

This yields the more well-known equation x2+y2=r2 for a circle centered at the (2,3).

Since we are aware that the circle's center is at (2,3), i.e.

This fact, together with the circle's intersection point (3,2), can be used to determine the radius. The distance formula is used for this.

r=√(x^2−x1)^2+(y2−y1)^2

In light of (2,3) and (3,2):

r=√(3−2)^2+(2−3)^2

r = √(1)^2+(-1)^2

= √1+1

=√2

⇒ r=√2

Therefore, x2+y2=(√2)^2

                   x2+y2=2 is the equation for the circle.

When pushing a car using a force of 500 N. The work done is 7500 Joule.

Force is a power that results in the motion of an object. It is calculated by newton. Distance is the measurement of two entities from one side to another side. It is calculated in meters and kilometers.

By multiplying the total force used, and the total distance traveled, the total work done may be calculated.

Given, the force is 500 N

Distance is 15 m

Total work done = force × distance

500 × 15 N = 7500 Joule

Hence, 7500 Joule work is done.

The width of a rectangle is 4 units less than the length. The width, in units, of the rectangle is 2 units.

Represent the length and width by L and W.

Then W = L - 4.

The area of the rectangle is 12 units

= Length x width  

=  L x W

=  L(L - 4)

=L^2 - 4L = 12

L^2 -4L - 12 = 0

Now on solving this quadratic equation we get

L^2 -4L - 12 = 0

L^2 - 6L  + 2L -12 = 0

L(L - 6 ) -2(L - 6) = 0

(L-6)(L-2) = 0

This factors easily into

(L - 2)(L - 6) = 0

so L must be 2,6.  

When L = 2

The width of the rectangle is W = L - 4 = 2 - 4 = -2 units.

We ignore the negative values.

when L= 6

The width of the rectangle is W = L - 4 = 6 - 4 = 2 units.

Answer:

The submarine will be at -50 feet after the descent.

Step-by-step explanation:

A submarine at -20 feet descends 30 feet. What is the submarine's current location after the descent?

If the starting point is -20 feet and it says that the submarine goes down another 30 feet we can write an equation and solve it.

Descending indicates going down or subtraction.

Let x=the current location after the descent.

-20+(-30)=x

-20-30=x

-50=x

The submarine will be at -50 feet after the descent.

By solving a system of equations we can see that Alang sold 25 pounds of blueberries and 45 pounds of grapes.

Here we need to define the variables:

g = pounds of grapes bought.

b = pounds of blueberries bought.

We know that:

"Alang sold 20 more pounds of grapes than pounds of blueberries and made $182.50 altogether."

then we can write the system of equations:

g = b + 20

g*3.5 + b*1 = 182.50

To solve this, we can replace the first equation into the second one, so we get:

(b + 20)*3.5 + b*1 = 182.50

b*4.5 + 70 = 182.50

b*4.5 = 182.50 - 70

b*4.5 = 112.50

b = 112.50/4.5 = 25

And we know that:

g = b + 20 = 25 + 20 = 45

So he sold 25 pounds of blueberries and 45 pounds of grapes.
