Mal works at a photo gallery. He charges $50 for a large photo and $40 for a large frame. Sales tax is 5%. How much total tax will a customer pay on both?
Answer the questions to show how to write and simplify expressions that represent the problem.

1. One way to calculate the total tax is 0.05(50 + 40). Use the order of operations to evaluate this expression.

2. Use the distributive property to expand 0.05(50 + 40).

3. Find the total tax using the expanded expression. Did you get the same answer as you did by evaluating the original expression?

4. Which expression, the original expression or the expanded expression, involves finding the total cost first, then calculating the tax on that total?

Answers

The cost of large photo after sales tax is $94.5.

Given that, Mal charges $50 for a large photo and $40 for a large frame. Sales tax is 5%.

Total cost of large photo = 50+40

= $90

Sales tax on large photo

= 5% of 90

= 5/100 ×90

= 0.05×90

= 4.5

Cost of large photo after tax = 90+4.5

= $94.5

Therefore, the cost of large photo after sales tax is $94.5.

Liza is designing a calendar as a fund-raising project for Math Class. The cost of printing
is 5000php, plus 150php per calendar. Write an equation in slope-intercept form that
models the total cost of printing the calendars.

Answers

Answer: y = 150x+5000

Step-by-step explanation:

Equation in slope-intercept form:

y= mx+c , where x= independent variable , y= dependent variable, m= slope , c= y-intercept.

Given: The cost of printing is 5000php, plus 150 php per calendar.

If x= Number of calendar and y= Cost of x calendars.

Then, m= 150 , c= 5000

Equation becomes

y = 150x+5000

Solve the following system of equations by graphing. y = –1∕2x – 2 y = –3∕2x + 2 Question 1 options: A) (3,–4) B) (4,–3) C) (–4,–4) D) (4,–4)

Surface Area of the box is 190" or in.

Step-by-step explanation:

We start by determining the surface area formula for the box, which is a rectangular prism:

S = 2(l*w+w*h+l*h), where S = surface area of rectangular prism, l = length, w = width, and h = height.

Since length = 7", width = 2", and height = 9", we can substitute the information given into the formula above.

S = 2((7*2)+(2*9)+(7*9))

= 2(14+18+63)

= 2(95)

= 190"

Surface Area of the box is 190" or in.

In the right triangle below, the measure of angle C is 90°, AB= 5 units, and CB = 2 units. What is tan B?

Answers

It’s the letter F. Hope this helps

The value of the tanB is root of 21/2

We have given that ,

C is 90 degrees and side AB=5 units and CB=2 units

We have to find the tan B

We have given that the right angle triangle.

What is the value of tan ratio?

[tex]tan\theta=\frac{opposite side}{adjucent side}[/tex]

Here opposite side side of B is AC and adjacent side of B is CB.

We know the side AB=5 units and CB=2 units

First we have to find the side AC

Therefore by using Pythagoras theorem,

[tex]AB^2=CB^2+AC^2[/tex]

[tex]AB^2-CB^2=AC^2\\25-4=AC^2\\21=AC^2\\[/tex]

Taking square root on both side we have

[tex]\sqrt{21}=AC\\ AC=\sqrt{21}[/tex]

Now we have the tan ratio,

[tex]tan\theta=\frac{opposite side}{adjucent side}\\\\tanB=\frac{AC}{CB}\\\\tanB=\frac{\sqrt{21} }{2}\\[/tex]

Therefore the option F is correct.

The value of the tanB is root of 21/2.
