Answer:
$13.68
Step-by-step explanation:
3.42 x 4
Final answer:
To find the total cost of 4 baseballs, each costing $3.42, we multiply the cost of one baseball by the number of baseballs, resulting in a total cost of $13.68.
Explanation:
The question asks to calculate the total cost of 4 baseballs, provided that each costs $3.42. To find the total cost, we need to multiply the cost of one baseball by the number of baseballs that were purchased. Hence, the calculation of the total cost of baseball is given by $3.42 (cost of one baseball) × 4 (number of baseballs) = $13.68. Therefore, the total cost of the 4 baseballs is $13.68.

Hope this helps.
To get back the original number after dividing by 9, one should multiply the result by 9, because multiplication and division are inverse operations.
The student's question asks: James thought of a number and divided it by 9. What can he do to get back his original number? The correct answer is (A) multiply by 9. When a number is divided by 9 to undo this operation one must multiply it by 9. This is because multiplication is the inverse operation of division. Therefore, if James wants to obtain his original number back, he should take the result he got after dividing by 9 and multiply it by 9.
A college football stadium holds 45,000 fans. In a random sample of 30 fans, 26 were wearing the colors of the home team. Predict the number of fans who are wearing the colors of the home team.
Answer:
38,999
Step-by-step explanation:
In your sample you have 26 out of 30. I like to get that number into a percentage, so you do 26 divided by 30
26/30 = .8666
Then you take your total amount of fans, 45,000 and multiply it by your percentage wearing team colors.
45,000 x .8666 = 38,999.97
Since you can't have .97 of a person, your round it down to 38,999.

Answer:
The correct answer is "Circle 1 is a translation of 1 unit right and 7 units up from Circle 2, and a dilation of Circle 2 with a scale factor of 1.6"
Step-by-step explanation:
We can tell this because first they identify the movement properly. When going from (-3, 0) to (-2, 7), we move to the right one and up 7.
Also, we know there is a scale factor of 1.6, because when we look at the radius of each circle, we can divide and find that factor.
8x/5x = 1.6

0.35
0.03
0.02
0.83
Answer:
P (S∩LC) = 0.03
Step-by-step explanation:
We are given that the probability that someone is a smoker is P(S)=0.19 and the probability that someone has lung cancer, given that they are a smoker is P(LC|S)=0.158.
Given the above information, we are to find the probability hat a random person is a smoker and has lung cancer P(S∩LC).
P (LC|S) = P (S∩LC) / P (S)
Substituting the given values to get:
0.158 = P(S∩LC) / 0.19
P (S∩LC) = 0.158 × 0.19 = 0.03

Which of the following shows the correct order of the numbers below?
First who answers will get brainlyest
Answer:
c)
Step-by-step explanation:
if you look at option c it would be correct because 0.75 (3/4) is bigger than 0.7. Then 11/12 is a bigger proportion then 0.75. there for your answer is correct.
The correct order of the numbers given when converted to decimals for easy comparison is 0.7, 3/4 and 11/12, which corresponds to option b: 0.7 < 3/4 < 11/12.
Explanation:This is a question about comparing and ordering fractions and decimals. To answer this, we first need to convert all the numbers into the same format. We can convert the fractions 11/12 and 3/4 into decimals for easier comparison.
First, to convert 11/12 to a decimal, you'll do the division to find approximately 0.9167. Secondly, 3/4 can be converted to a decimal by performing 3 divided by 4, which equals 0.75. Now, we can easily compare these decimals to 0.7.
From this, we can see that 0.7 is less than 0.75 (3/4) and both 0.7 and 0.75 are less than 0.9167 (11/12). So the correct order of the numbers from least to greatest would be 0.7 < 3/4 < 11/12.
So the correct option is b. 0.7 < 3/4 < 11/12.

Before she went on a diet, Jenna's waist measured 32.45 inches.After the diet, it measured 26.97 inches.How many inches did Jenna lose?
Answer:
5.48
Step-by-step explanation:
32.45 - 26.97 = 5.48
Answer:
Jenna lost 5,48
Step-by-step explanation:
Before the diet Jenna's waist measured 32.45 inches.
After the diet Jenna's waist measured 26.97 inches.
To get the difference between the two measures, we have to discount the new measure from the previous one.
So, difference is 26.97 inches-32.45 inches= -5,48. It is negative because she lost inches.

In circle O, the measure of ∠ROW is 110°. What is the measure of arc RAW?
Answer:
250°
Step-by-step explanation:
We know that a circle has a total of 360°.
Now we know that ∠ROW is 110° and that Arc RAW has the same End points as ∠ROW.
We can safely assume that arc RAW will be the difference of ∠ROW and 360°.
So we then get:
360° - 110° = 250°
This means that Arc RAW will be 250°
The function below has been transformed from f(x) = x2. Describe the transformation. h(x) = 4x2 + 12
Answer:
vertically expanded by a factor of 4then, translated upward 12 unitsStep-by-step explanation:
If f(x) = x² and g(x) = 4x² = 4f(x), the function g(x) represents a vertical expansion of f(x) by a factor of 4.
If h(x) = g(x) +12, the function h(x) represents a translation of g(x) by 12 units upward.
Together, these transformations on f(x) are ...

David and Tonya each cut a cylinder in half. The cross-section that results from David's cut is a rectangle. The cross-section that results from Tonya's cut is a circle.
Answer:
Tonya cut the cylinder vertically and David cut it diagonally.
David’s cut along the length of his cylinder resulted in a rectangular cross-section, while Tonya’s perpendicular cut resulted in a circular cross-section. This illustrates principles of geometric cross-sections and plane intersections with solids.
Explanation:In the problem described, David and Tonya are each cutting a cylinder, a geometric shape. The cuts they make, and the cross-sections they create, depend on the orientation of their cuts in relation to the shape of the cylinder.
When David cuts the cylinder, his cross-section result is a rectangle. This implies that he made a longitudinal cut along the length of the cylinder, essentially splitting it from top to bottom.
When Tonya cuts her cylinder, the cross-section is a circle. This means she made a cross-sectional cut perpendicular to the length of the cylinder, slicing it into two equal half cylinders.
This problem illustrates the principles of geometric cross-sections and plane intersections with solids, which are part of the broader field of study in geometry.
