Answer:

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.

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

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.

When one bird in a colony spots a predator, it flies up and sounds an alarm. All the nearby birds then fly up and give alarm calls too. If the alarm is strong enough, it travels through the colony like a wave. Soon most of the birds in the colony are airborne. The alarmed birds scream, dive-bomb, and harass the predator to drive it away. People who walk near colonies of nesting birds often get mobbed in the same way that a fox, a coyote, or an eagle might. The gulls' reaction to Larry was nothing more than an intense display of their natural behavior toward a feared predator.Question 1Part AWhich inference can be drawn from the paragraph from "The Day the Gulls Went Crazy"? Larry was the first person to be attacked by gulls. Colonial birds have a weak response toward predators. Birds lack the ability to communicate with each other. Nesting colonial birds may consider people a threat.Question 2Part BWhich textual evidence best supports the answer to Part A? "If the alarm is strong enough, it travels through the colony like a wave." "People who walk near colonies of nesting birds often get mobbed in the same way that a fox, a coyote, or an eagle might." "The alarmed birds scream, dive-bomb, and harass the predator to drive it away." "When one bird in a colony spots a predator, it flies up and sounds an alarm."
