Question
Ms. Garcia burns 236 calories riding her bike each hour. She wants to burn more than 354 calories riding her bike at the same rate.
Which inequality represents all possible values for t, the number of hours Ms. Garcia must ride her bike to burn more than 354 calories?
Responses
A t < 1.5t < 1.5
B t < 0.5t < 0.5
C t > 1.5t > 1.5
D t > 0.5
To burn more than 354 calories, we can use the inequality:
236t > 354
Dividing both sides by 236, we get:
t > 354/236
Simplifying, we get:
t > 1.5
Therefore, the answer is C. t > 1.5.
A Scientist used 6.87 liters of a liquid for an experiment. How many milliliters of the liquid did the scientist use for this experiment?
Responses
A 68,700 mL68,700 mL
B 687,000 mL687,000 mL
C 6,870 mL6,870 mL
D 687 mL
To convert liters to milliliters, we need to multiply by 1000.
6.87 liters x 1000 mL/liter = 6870 mL
So, the scientist used 6870 mL of the liquid for the experiment.
Therefore, the answer is C. 6,870 mL.
Carolina walked to school on 12 of the 20 school days in March. Which value is NOT equivalent to the fraction of the school days in March that Carolina walked to school?
Responses
A 3/53/5
B 60%60%
C 0.060.06
D 0.600.60
The fraction of the school days in March that Carolina walked to school is:
12/20
Simplifying, we get:
3/5
So, the other options also need to be converted to 3/5:
A. 3/5 - This is equivalent to 3/5.
B. 60% = 0.6, and when we convert this to a fraction, we get 3/5. So, this is equivalent to 3/5.
C. 0.06 = 6/100, and when we simplify this fraction, we get 3/50. This is NOT equivalent to 3/5.
D. 0.60 = 60/100, and when we simplify this fraction, we get 3/5. So, this is equivalent to 3/5.
Therefore, the answer is C. 0.06.

Question
On Sunday Calvin gave his guinea pig 80 grams of food. The table shows the amount of each type of food he gave to the guinea pig.
Which percentage bar graph best represents the data?
Responses
A Graph BGraph B
B Graph DGraph D
C Graph CGraph C
D Graph A
To determine the correct percentage bar graph, we need to calculate the percentage of each type of food out of the total amount of food given to the guinea pig.
The total amount of food given to the guinea pig is:
80 g
The amount of carrots given is:
30 g
So, the percentage of carrots is:
(30/80) x 100% = 37.5%
The amount of kale given is:
12 g
So, the percentage of kale is:
(12/80) x 100% = 15%
The amount of pellets given is:
38 g
So, the percentage of pellets is:
(38/80) x 100% = 47.5%
Using these percentages, we can see that Graph C best represents the data.
Therefore, the answer is C. Graph C.

Question
The dimensions of a lawn shaped like a trapezoid are given in meters. What is the area of the lawn in square meters?
Responses
A 100 m2
100 m 2
B 39 m2
39 m 2
C 60 m2
60 m 2
D 30 m2
The formula for the area of a trapezoid is:
A = (b1 + b2) x h / 2
where b1 and b2 are the base lengths and h is the height.
We need to use the given dimensions to calculate the area of the lawn. From the diagram, we see that:
b1 = 10 m
b2 = 20 m
h = 4 m
Substituting these values into the formula, we get:
A = (10 + 20) x 4 / 2
A = 30 x 4
A = 120
Therefore, the area of the lawn is 120 square meters.
So, the answer is not listed among the given options.
Which situation can be represented by the equation y = x + 15?
Responses
A Vince is y years old. His age is 15 years greater than x, his brother's age in years.Vince is y years old. His age is 15 years greater than x, his brother's age in years.
B Vince spent x dollars to buy a gift for his brother. He gave the cashier y dollars and received $15 in change.Vince spent x dollars to buy a gift for his brother. He gave the cashier y dollars and received $15 in change.
C Vince went to school for x years. This is 15 times y, the number of years his brother went to school.Vince went to school for x years. This is 15 times y, the number of years his brother went to school.
D Vince has y dollars. This amount is 15 times x, the amount of money in dollars Vince's brother has.Vince has y dollars. This amount is 15 times x, the amount of money in dollars Vince's brother has.
The equation y = x + 15 represents the situation where Vince is y years old. His age is 15 years greater than x, his brother's age in years.
Therefore, the answer is A. Vince is y years old. His age is 15 years greater than x, his brother's age in years.
The ratio of the number of boys to the number of girls in a choir is 6 to 5. There are 45 girls in the choir. How many boys are in the choir?
Responses
A 5454
B 66
C 3939
D 6161
The ratio of boys to girls is 6:5. This means that for every 6 boys, there are 5 girls.
If there are 5 girls in the choir, then we can set up a proportion to find out how many boys are in the choir:
6/5 = x/45
where x is the number of boys.
To solve for x, we can cross-multiply:
6 x 45 = 5 x
270 = 5x
x = 54
Therefore, there are 54 boys in the choir.
So, the answer is A. 54.

Question
The dot plot shows the wing lengths in millimeters for ten birds.
Which statement is NOT supported by the data in the dot plot?
Responses
A Most of the birds measured had a wing length of 48 mmMost of the birds measured had a wing length of 48 mm
B Less than half of the birds have wing lengths of less than 50 mmLess than half of the birds have wing lengths of less than 50 mm
C More than half of the birds have wing lengths of at least 48 mmMore than half of the birds have wing lengths of at least 48 mm
D The same number of birds have a wing length of 54 mm as birds that have a wing length of 46 mm
From the dot plot, we can see that:
- There is one bird with a wing length of 46 mm
- There is one bird with a wing length of 50 mm
- There are three birds with a wing length of 52 mm
- There are two birds with a wing length of 54 mm
- There are three birds with a wing length of 48 mm
Therefore, the statement that is NOT supported by the data in the dot plot is:
D. The same number of birds have a wing length of 54 mm as birds that have a wing length of 46 mm.
This is not supported because there is only one bird with a wing length of 46 mm, while there are two birds with a wing length of 54 mm.
So, the answer is D.
The weights of four puppies are shown in pounds.
8.25, 8 and 1/8, 8.625, 8 and 1/2
List the weights in order from LEAST to GREATEST.
Responses
A 8 and 1/2, 8.25, 8.625, 8 and 1/88 and 1/2, 8.25, 8.625, 8 and 1/8
B 8.25, 8.625, 8 and 1/2, 8 and 1/88.25, 8.625, 8 and 1/2, 8 and 1/8
C 8 and 1/8, 8.25, 8 and 1/2, 8.6258 and 1/8, 8.25, 8 and 1/2, 8.625
D 8.625, 8 and 1/2, 8.25, 8 and 1/8
To order the given weights from least to greatest, we need to convert the mixed numbers to decimals or fractions.
8 and 1/8 = 8.125
8 and 1/2 = 8.5
Now we can order the weights:
8.125, 8.25, 8.5, 8.625
Therefore, the answer is C. 8 and 1/8, 8.25, 8 and 1/2, 8.625.
