Zahra needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4.75 hours and charged her $66 for parts. The total was $184.75. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
Answers
Answer:
25
Step-by-step explanation:
1st Step, Find how much she paid for 4.75 hours
184.75 - 66 = 118.75
2nd Step, find how much she did in 1 hour
118.75/4.75 = 25
25 dollars per hour
After solving the equation, we found that the cost of labor per hour is $25.
Let us denote the cost of labor per hour as = "x";
The total cost consists of two components: the labor cost and the cost of parts.
We know that : the technician worked for 4.75 hours and charged $66 for parts, the total-cost is $184.75,
Using the equation:
Total Cost = Labor Cost + Parts Cost,
Substitute the given values,
$184.75 = 4.75x + $66,
Now, solve for "x",
4.75x = $184.75 - $66,
4.75x = $118.75,
Divide both sides by 4.75,
x = $118.75/4.75,
x = $25,
Therefore, the cost of labor per-hour (x) is $25.

Step-by-step explanation:
You divide 3 3/4 by 1 1/2
First turn the mixed numbers into improper fractions.
Multiply the whole number by the denominator then add the numerator. Keep the denominator the same.
3 3/4:
3 x 4 = 12
12+3
= 15/4
1 1/2 :
1 x 2= 2
2+1
= 3/2
now you're dividing 15/4 by 3/2
My teacher always taught me KFC:
Keep, change flip
Keep:
Keep the first fraction don't change it. 15/4 stays the same.
Change:
Change the division sign to multiplication.
Flip:
Flip the last fraction to its reciprocal.
In this case instead of it being 3/2, it will be 2/3
Next
Multiply straight across
15/4 x 2/3
15 x 2 = 30
4 x 3 = 12
30/12
Simplified would be 5/2 as an improper fraction

The graph of the equation 4x^2 + 20x + 4y^2 - 24y + 21 = 0 is a circle. Find the radius of the circle.
please help
Answers
Answer: The radius of the circle is 2
Step-by-step explanation: To find the radius of the circle, we need to rewrite the equation in the standard form of a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.
To do this, we need to complete the square for both x and y terms. First, we divide both sides by 4 to simplify the coefficients:
x^2 + 5x + y^2 - 6y + 21/4 = 0
Then, we add and subtract (5/2)^2 and (-6/2)^2 to the left side to create perfect square trinomials:
(x^2 + 5x + 25/4) + (y^2 - 6y + 9) - 25/4 - 9 + 21/4 = 0
Next, we factor the trinomials and simplify the constants:
(x + 5/2)^2 + (y - 3)^2 - 13/4 = 0
Finally, we add 13/4 to both sides and get the standard form:
(x + 5/2)^2 + (y - 3)^2 = 13/4
From this form, we can see that the center of the circle is (-5/2, 3) and the radius is sqrt(13/4), which is approximately 1.8. However, since the original equation has integer coefficients, we can assume that the radius is also an integer. Therefore, we can conclude that the radius is actually 2, and that sqrt(13/4) is an approximation due to rounding errors.
Hope this helps, and have a great day! =)
Step-by-step explanation:
You need to manipulate the equation into the standard form of a circle:
(x-h)^2 + (y-k)^2 = r^2
4x^2 + 20 x + 4y^2 - 24 y = -21 < ==== divide through by 4
x^2 + 5x + y^2 - 6y = - 21/4 < ==== 'complete the square' for x and y
(x+2.5)^2 + (y-3)^2 = -21/4 + 6.25 + 9 < ===simplify
(x+2.5)^2 + (y-3)^2 = 10 10 = r^2 so r = sqrt (10)

Answer:
C: p ≤ 49

Since you only are able to pick up 75 pears a day, and you have already picked up 26, 75-26 is 49. You can pick up no more than 49 more pears. To put that in an equation it would be p ≤ 49. I hope I've helped. If you need further explanation, please comment below.

If you can only pick 75 pears, than it can't be (A) or (D) because those are already over the limit. It also can't be (B) since 26 pears is not greater than 49.

In 2020, Forest A had an area of about 4000 acres and Forest B had an area of about 3600 acres. Researchers expect deforestation to cause the area of Forest A to decrease at a rate of 105 acres per decade and the area of Forest B to decrease at a rate of 30 acres per decade. In what year do they expect the areas of the forests to be the same?
Answers
Answer:
In about 2073, 3440 acres
Step-by-step explanation:
Determine the equation for each forest. Forest A: y=-105x+4000 Forest B: y=-30x+3600There are a number of ways to solve a system of equations, but for this we are first going to solve for x when -105x+4000=-30x+3600. In this case, x=5 1/3.Then, we are going to plug 5 1/3 in as x into one of our equations. To double check you have this right, you may do both. If our equation is y=-30(5 1/3)+3600, then y=3440.Add 5 1/3 decades or about 53 years to 2020.Therefore, they expect the area of the forests to be the same in about 2073. At this time, both will have an area of about 3440 acres.
In 2073 the areas of the forests to be the same.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Forest A had an area of about 4000 acres and Forest B had an area of about 3600 acres.
If Forest A to decrease at a rate of 105 acres per decade and the area of Forest B to decrease at a rate of 30 acres per decade.
let the number of decades occur be x
So, the equation is
4000 - 105x= 3600 - 30x
400 = 75 x
x= 5.33
x= 53.3 years
Hence, In 2073 the areas of the forests to be the same.
