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.

What is the solution set to the equation (3x−9)(5x−3)=0?
{35,3}
{3}
{35,53}
{−3,−35}
Answers
Answer:
{ [tex]\frac{3}{5}[/tex], 3 }
Step-by-step explanation:
Given
(3x - 9)(5x - 3) = 0
Equate each factor to zero and solve for x
3x - 9 = 0 ( add 9 to both sides )
3x = 9 ( divide both sides by 3 )
x = 3
and
5x - 3 = 0 ( add 3 to both sides )
5x = 3 ( divide both sides by 5 )
x = [tex]\frac{3}{5}[/tex]

A car is merging onto a freeway (beginning at rest), accelerating at a constant rate of 10ft/sec2. How long does it take to reach merging speed at 70mph?
Answers
Answer:
10.3secondsStep-by-step explanation:
Step one:
given data
acceleration,a= 10ft/sec^2
final velocity v= 70mph
first, let is convert mph to ft/sec
1mph is 1.46667 ft/sec
70 mph is x
cross multiply we have
x= 102.7ft/s
Step two:
we are using the first equation of motion
v=u+at
initial velocity u= 0m/s
102.7=0+10*t
102.7=10t
divide both sides by 10
t=10.3seconds

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

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.
