cost after tax to repair it is represented by 0.09(75h) + 75h, where h represents the number of hours it takes to repair her computer. What part of the expression represents the amount of tax Mrs. Bull has to pay? I need the total tax that she paid, and please explain it! Thank you!

0.09(75h) is the part of the expression that represents the amount of tax Mrs.Bull has to pay. 75h (h representing the number of hours it will take to repair the laptop) is the amount before tax, so 0.09 and 75h multiplied will equal the total of tax.


Hope this helps you

I’d say that the repair costs 75$/hour which then leaves the tax to be 0.09

What is the value of y?
Xelga [282]

Answer:

y = 54

Step-by-step explanation:

We know the sum of the angles of a triangle are 180

72+y+y = 180

Combine like terms

72 + 2y = 180

Subtract 72 from each side

72-72 +2y = 180-72

2y = 108

Divide each side by 2

2y/2 = 108/2

y = 54

an isosceles triangle has a vertex angle of 21.21 degrees. two sides of the triangle are each 17.91 ft long. whats the area of t
lubasha [3.4K]

Answer:

The area of triangle is A=58.02\ ft^{2}

Step-by-step explanation:

Let

B -----> the measure of the vertex angle of the isosceles triangle ABC

a and c -----> the two congruent sides of the isosceles triangle ABC

we know that

The area of a triangle applying the law of sines is equal to

A=\frac{1}{2}(a)(c)sin(B)

we have

a=c=17.91\ ft

B=21.21\°

substitute in the formula

A=\frac{1}{2}(17.91)(17.91)sin(21.21\°)

A=58.02\ ft^{2}

Please answer this correctly without making mistakes
Gekata [30.6K]

Answer:

16

Step-by-step explanation:

The distance is given by

d = sqrt( (x2-x1) ^2 + ( y2-y1) ^2)

Since the x values are the same

d = sqrt(  ( y2-y1) ^2)

d = sqrt(  (( -6 - 10)^2))

d =  sqrt((-16) ^2)

d = 16

We can also just find the number of squares between the points since the x value is the same.

10 - -6

10+6

16
