The table shows the number of trees at Citrus Orchards. What is the ratio of orange trees to the total number of trees?

Answer explanation

This ratio is asking for the number of orange trees to the TOTAL number of trees. To get the total, you need to add up all the kinds of trees (including orange trees). Then you need to SIMPLIFY your ratio to see which multiple choice ratio matches!

What is the area of the triangle?

• 160 ft²

• 58 ft²

• 80 ft²

• 88 ft²

Answer explanation

Remember to find the area of a triangle you need to multiply the base times the height and then divide by 2. The base and height MUST be perpendicular to each other. (You know they are perpendicular because they have a little square in the corner where the lines connect). The base is always one of the side lengths but the height is often shown as a dotted line (either inside or outside the triangle). The only time the height is a side length is when you have a right triangle.

A houseware shop receives a shipment of 125 dishes in 5 boxes. At this rate, how many dishes will it receive in 15 boxes?

• 25

• 45

• 375

• 625

Answer explanation

Read the question carefully. They already tell you the amount for 5 boxes and you must scale up to 15 boxes. This is just 3 times the amount that you already have.

A diagram of a rectangular flag, with a shaded section, is shown here. What is the area, in square centimeters, of the shaded section of the flag? SHOW YOUR WORK on paper or on a print screen, and then attach a photo of your work to this quizizz.

(This was a 2 credit question from last year's state exam. If you had the correct answer with no work, you received 0 credit).

Mathematical Equivalence

ON

Answer explanation

There are a few ways to solve this.

One way is to find the area of the entire rectangle (shaded & unshaded), then find the area of the unshaded triangle to the right and then subtract.

Remember:

Area of a rectangle is base times height.

Area of a triangle is 1/2 times base times height. Or base times height divided by 2.
