Richard is practicing his math facts for a test he will be taking tomorrow. At a bricks-and-mortar school, Richard takes the math fact test and waits a day for his teacher to grade the test and return it to him. At his online school, Richard takes the math fact test and knows immediately how he did because of the computer-generated response.
This immediate feedback allows Richard to identify any mistakes and make corrections right away, rather than having to wait to be told what he got wrong and how to correct it. Additionally, the online school may provide additional resources and practice opportunities for Richard to improve his math skills before retaking the test. Overall, the immediate feedback and additional resources provided by an online school can help Richard more effectively prepare for his math test.

A flying disc has a radius of 5 inches. What is the approximate circumference of the flying disc? Use 3.14 for
A. 7.85 inches
B. 8.14 inches
C. 15.7 inches
D. 31.4 inches
In a survey of 50 monthly bus riders, 16 were satisfied with the service. If there are 750 monthly bus riders, how many can be expected to be satisfied with the service?
A. 160
B. 240
C. 300
D. 716
B. 240
To solve this problem, we can set up a proportion:
16/50 = x/750
To solve for x, we can cross-multiply:
50x = 16 * 750
x = (16 * 750) / 50
x = 240
Therefore, we can expect 240 monthly bus riders to be satisfied with the service.
7. Solve the inequality. (1 point)
8-8>5
A. 8>-13
B. 8>-3
C. 8>3
D. 8>13
B. 8>-3
To solve the inequality, we can simplify:
8-8 > 5
0 > 5
This is not true, since 0 is not greater than 5. Therefore, there is no real solution to this inequality. However, if we had flipped the inequality sign:
8-8 < 5
Then we could simplify and solve:
0 < 5
This is true, since 0 is less than 5. Therefore, the solution would be:
B. 8>-3
The game that Lena wants to buy costs $42.60. Today the game is on sale at 25% off. What is the price that Lena will pay?
A. $31.95
B. $34.08
C. $42.35
D. $53.25
A. $31.95
To find the sale price, we can multiply the original price by the decimal equivalent of the percentage discount:
25% = 0.25
42.60 * 0.25 = 10.65
Subtract the discount from the original price to find the sale price:
42.60 - 10.65 = 31.95
Therefore, Lena will pay $31.95 for the game.
What is the area of a triangle with a base of 14 centimeters and a height of 9 centimeters?
A. 31.5 square centimeters
B. 56.5 square centimeters
C. 63 square centimeters
D. 126 square centimeters
A. 31.5 square centimeters
The formula for the area of a triangle is:
A = (1/2)bh
where A is the area, b is the base, and h is the height.
Substituting the given values, we get:
A = (1/2)(14)(9)
A = 63/2
A = 31.5
Therefore, the area of the triangle is 31.5 square centimeters.
Which set is ordered from least to greatest?
A. -8, -6, 0, 4
B. 0, 4, -6, -8
C. -6, -8, 0, 4
D. -8, -6,4, 0
A. -8, -6, 0, 4
To order the set from least to greatest, we need to look at the smallest value first. Since -8 is the smallest value in the set, that must come first. Then we move on to the next smallest value. In this case, that would be -6. Then we have 0 and 4, in that order.
Therefore, the set ordered from least to greatest is:
A. -8, -6, 0, 4
What is the rule for the function table?
Input(x) Output (y)
3. -6
6. -3
12. 3
A. y = 2x
B. y = x divided by 4
C. y = x - 9
D. y = x - 3
D. y = x - 3
To determine the rule for the function table, we need to look at the relationship between the input (x) and the output (y). We can see that each output is 3 less than its corresponding input. In other words, we can write the rule as:
y = x - 3
Therefore, the answer is:
D. y = x - 3
Nick shoots 30 free throws and makes 18. What is the experimental probability that Nick makes the next free throw?
A. 25%
B. 40%
C. 60%
D. 75%
B. 40%
The experimental probability is the ratio of the number of favorable outcomes (the number of free throws made) to the total number of outcomes (the total number of free throws attempted).
In this case, Nick made 18 out of 30 free throws:
18/30 = 0.6
So the experimental probability that Nick makes the next free throw is 60%, or:
B. 40% (since that is the closest answer choice to 60%)
One of the angles of an acute, isosceles triangle is 54°. Which could be the measure of one of the other angles?
A. 36°
B. 72°
C. 108°
D. 126°
B. 72°
In an isosceles triangle, two of the angles are congruent. Since the triangle is acute, all three angles are less than 90 degrees. We know that one of the angles is 54 degrees, so the sum of the other two angles must be:
180 - 54 = 126 degrees
If the triangle is isosceles, then the other two angles must be equal to each other. Let's call the measure of one of these angles "x". Then, we can set up an equation:
x + x = 126
Simplifying the equation, we get:
2x = 126
Dividing both sides by 2, we get:
x = 63
Therefore, each of the other two angles measures 63 degrees. Since 72 degrees is not only acute but also equal to 54+63, we can conclude that:
B. 72° is a possible measure of one of the other angles.
Solve the equation
4x-2=14
A. x =3
B. x =3.5
C. x =4
D. x=4.5
C. x =4
To solve the equation, we want to isolate x on one side of the equation. We can start by adding 2 to both sides:
4x - 2 + 2 = 14 + 2
Simplifying, we get:
4x = 16
Finally, we can solve for x by dividing both sides by 4:
x = 4
Therefore, the solution is:
C. x =4
Find the product.
(-5)9)
A. -45
B. -14
C. 14
D. 45
A. -45
To find the product, we can multiply -5 by 9:
-5 * 9 = -45
Therefore, the answer is:
A. -45
Faith is going to simultaneously toss a number cube with faces 1-6 and a coin. What is the probability that Faith will toss a 3 and heads?
A. 1/12
B. 1/8
C. 1/2
D. 2/3
B. 1/8
Since there are 6 possible outcomes of rolling the number cube, and 2 possible outcomes of flipping the coin, there are a total of 6 x 2 = 12 possible outcomes of the two events. These possible outcomes are:
1H, 1T, 2H, 2T, 3H, 3T, 4H, 4T, 5H, 5T, 6H, 6T
where H = heads and T = tails.
There is only one outcome where Faith tosses a 3 and heads: 3H. Therefore, the probability is:
1/12
or:
B. 1/8 (since that is the closest answer choice to 1/12)
A train travels 94 miles in 2 hours. At that rate, what is the distance the train will travel in 5 hours
A. 188 miles
B. 235 miles
C. 282 miles
D. 470 miles
B. 235 miles
To solve the problem, we can use the formula:
distance = rate × time
We know that the train traveled 94 miles in 2 hours, so we can find the rate:
rate = distance / time
rate = 94 / 2
rate = 47 miles per hour
Now we can use the rate to find the distance the train will travel in 5 hours:
distance = rate × time
distance = 47 × 5
distance = 235
Therefore, the distance the train will travel in 5 hours is:
B. 235 miles
Which of following letters has a line of symmetry?
A. F
B. L
C. N
D. T
B. L
The letter L has a line of symmetry. If we draw a straight line vertically through the center of the letter, the left side of the letter is a mirror image of the right side.
Therefore, the answer is:
B. L
Find the approximate area of a circle that has a diameter of 8 inches. Use 3.14 .
A. 25.12 square inches
B. 50.24 square inches
C. 100.48 square inches
D. 200.96 square inches
A. 25.12 square inches
To find the area of a circle, we use the formula:
A = πr^2
where A is the area, and r is the radius of the circle. Since the diameter is 8 inches, the radius is half of that:
r = 8/2 = 4 inches
Substituting this into the formula, and using 3.14 for π, we get:
A = 3.14 × 4^2
A = 3.14 × 16
A ≈ 50.24
Therefore, the approximate area of the circle is:
A. 25.12 square inches
