Ella needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 3 hours and charged her $61 for parts. The total was $226. Write and solve an equation which can be used to determine x, the cost of the labor per hour

Answer:

I'm not sure if B. is incorrectly written but the answer would be

65c + 90s [tex]\geq[/tex]600

Step-by-step explanation:

since he needs AT LEAST 600$ then the sign should look like that. 65 dollars per car, and c represents the amount of cars, and 90 per SUV and s represents how many SUVS

B. 65c + 90s ≥ 600 is the correct option.

Our friend really wants to buy the newest cell phone which will cost him $600. He gets a job detailing cars and SUVs and plans to save all the money he earns.

Inequality can be defined as the relation of the equation contains the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,

If he gets paid $65 to detail a car and $90 to detail an SUV

The inequality form for above condition so he can earn at least $600

= 65c + 90s ≥ 600, where c = cars and s = SUV

Thus, the required inequality is given by 65c + 90s ≥ 600.

The inequality that explains why the three segments cannot be used to construct a triangle is ED + EF < DF

From the question, we are to determine which of the given inequalities explains why the three segments cannot be used to construct a triangle

From the given information,

Line DE is about half the length of line DF

That is,

ED = 1/2 DF

Also,

Line FE is about one-third of the length of line DF

That is,

EF = 1/3 DF

Then, we can write that

ED + EF = 1/2DF + 1/3DF

ED + EF = 5/6 DF

Since,

5/6 DF < DF

Then,

ED + EF < DF

Hence, the inequality that explains why the three segments cannot be used to construct a triangle is ED + EF < DF

The equation representing the given case is 2(x - 8) = 3(x + 3), where x is the number.

The number satisfying this equation is -25.

In the question, we are asked to find the number when twice the difference of the number and 8 is equal to thrice the sum of the number and 3.

We assume the number to be x.

The expression representing twice the difference between the number and 8, can be shown as 2(x - 8).

The expression representing thrice the sum of the number and 3, can be shown as 3(x + 3).

We are informed that these two expressions are equal. This can be shown as the equation:

2(x - 8) = 3(x + 3).

Thus, the equation representing the given case is 2(x - 8) = 3(x + 3), where x is the number.

Now, to find the number, we solve the equation as follows:

2(x - 8) = 3(x + 3),

or, 2x - 16 = 3x + 9 {Simplifying},

or, 2x - 16 + (16 - 3x) = 3x + 9 + (16 - 3x) {Adding (16 - 3x) to both sides of the equation},

or, 2x - 16 + 16 - 3x = 3x + 9 + 16 - 3x {Simplifying},

or, -x = 25 {Simplifying},

or, -x(-1) = 25(-1) {Multiplying both sides of the equation with -1},

or, x = -25 {Simplifying}.

Thus, the number satisfying the equation is -25.

Hope this helps!

Answer:

6. x + x + 14 = 90

   2x + 14 = 90

   2x = 76

   x = 38

angle b = 38 + 14 = 52°

7. angles on a straight line add up to 180°

   x + x - 32 = 180

   2x = 212

    x = 106°

angle d = 106 - 32 = 74°

8. vertically opposite angles are equal

   7x - 80 = 3x

    -80 = -4x

     20 = x

angle 1 = 7(20) - 80 = 60°

angle 2 = 3(20) = 60°

The area of ​​the trapezoid is x+11 cm.

Given a trapezoid has one side of (x+6) cm, the other side is 5 cm, and the height is 2 cm.

A two-dimensional quadrilateral consisting of the sum of non-adjacent parallel sides and a suitable non-parallel side is denoted as a trapezoid.

Now we will use the formula to find the area of ​​a trapezoid

Area = 1/2 × (base 1 + base 2) × height

Here base 1 = (x+6) cm, base 2 = 5cm and height = 2cm

Substituting the values ​​into the formula,  we get

Area = 1/2 × (x+6+5) × 2

Area = 1/2 × (x+11) × 2

Area = x+11

Thus, the area of ​​the given figure when one side is x+6, the other side is 5 cm and the height is 2 cm is x+11 cm.

The confidence interval for the mean usage of water is (18.7,20.5).

Given population standard deviation of 2.4, mean of 19.5 gallons per day and confidence interval of 98%.

We have to find the confidence interval for the mean usage of water.

To find out the confidence interval we have to first find margin of error.

μ=19.5

σ=2.4

α=0.98

α/2=0.49

We have to find the z value for the p value 0.49 which is z=2.33

Margin of error=z*μ/[tex]\sqrt{n}[/tex]

=2.33*19.5/[tex]\sqrt{3034}[/tex]

=0.82

lower level=mean -m

=19.5-0.82

=18.68

after rounding upto 1 decimal

=18.7

upper mean = mean+m

=19.5+0.82

=20.52

Hence the confidence interval for the usage of water is (18.7,20.52).

The area of rectangle Q is; y × (1.25 × 40) = 50y.

Hence, since the area of Q is 10% less than the area of P, it follows that A(q) = 0.9A(p).

And, A(p)/A(q) = 10/9
