The price of oil recently went from $7.80 to$10.40 per case of quarts. Find the ratio of the increase in price to the original price.

Answers

Answer 1

Hello,

When you are looking for a ratio, it is simply a fraction.

In the numerator, we will put the amount of the increase which is 10.4 - 7.80 = 2.6.
In the denominator, we will put the original price of $7.80.

This gives us the ration of 2.6/7.8 or just 0.33 if we divide.
We can say there was a 33% increase (or one-third).

I hope this helps, Good luck!

a worker is tiling the floor of a rectangular room that is 12 feet by 15 feet. THe tiles are square with side lengths 1 1/3 feet. How many tiles are needed to cover the entire floor?

Answers

area of room: 12 x 15 = 180 square feet
area of 1 tile = 1 1/3 x 1 1/3 = 1.78 square feet
round to 1.8

180 / 1.8 = 100 tiles are needed

Answer:

102 tiles needed to cover the entire floor.

Step-by-step explanation:

Given : A worker is tiling the floor of a rectangular room that is 12 feet by 15 feet. The tiles are square with side lengths [tex]1\frac{1}{3}[/tex] feet.

To find : How many tiles are needed to cover the entire floor?

Solution :

A rectangular room that is 12 feet by 15 feet.

The area of the room is [tex]A=L\times B[/tex]

[tex]A_r=15\times 12[/tex]

[tex]A_r=180\ ft^2[/tex]

The tiles are square with side lengths [tex]1\frac{1}{3}=\frac{4}{3}[/tex] feet.

The area of the tile is [tex]A_t=s^2[/tex]

[tex]A_t=(\frac{4}{3})^2[/tex]

[tex]A_t=\frac{16}{9}\ ft^2[/tex]

Number of tiles needed to cover the entire floor is

[tex]n=\frac{A_r}{A_t}[/tex]

[tex]n=\frac{180}{\frac{16}{9}}[/tex]

[tex]n=\frac{180\times 9}{16}[/tex]

[tex]n=101.25[/tex]

Therefore, Approximately 102 tiles needed to cover the entire floor.

John walks 1 mile west. Then he turns north and walks another 2 miles before he stops to rest. How far is John from his starting point when he stops to rest? Round your answer to the nearest tenth.

Answers

You might think at first that he is 3 miles from his starting point, but if you think about it, that's not true. This forms a right triangle with one side of 2, the other side with 1, and the unknown distance as the hypotenuse. We can use Pythagorean's Theorem to solve this:
[tex]a^2 + b^2 = c^2[/tex]
[tex]c = \sqrt{a^2+b^2} = \sqrt{2^2+1^2} = \sqrt{5} [/tex]

This cannot be simplified anymore, so the distance John travels is [tex] \sqrt{5}[/tex] miles. You can put this into a calculator to get a value of 2.2 miles (rounding to the nearest tenth).

If you multiply/divide the numerator and denominator of a fraction by the same number, you will get an equivalent fraction.

For the first one, 6 is in the new numerator. Let's divide this by the original numerator to see what they did.

30/6 = 5

So they divided the numerator by 5. To get an equivalent fraction, we must do the same to the denominator.

35/5 = 7

So our new equivalent fraction is 6/7.

For the second one, the new denominator is 5. Let's see what they did to get this.

40/5 = 8

So they divided the denominator by 8 to get 5, let's do the same to the numerator:

8/8=1

So we have 1/5.

For the last one, they have 4 in the new denominator. Let's see what they did to get this denominator:

20/4 = 5

So they divided the denominator by 5, let's do the same thing to the numerator:

The wildflowers began blooming by my house at the beginning of March. The first week there were 88 blooms. After week two, there were 176 flowers in bloom. If the flowers continue to bloom at the same rate each week, how many flowers will there be after 6 weeks?
A. 264
B. 462
C. 528
D. 536

Answers

88+88= 176 Two weeks
176+88= 263 Three weeks
264+88=352 Four weeks
352+88=440 Five weeks
440+88=528 Six weeks
The answer is C.

The number of wildflowers is doubling each week. Starting with 88 blooms in the first week and 176 in the second, the pattern suggests that there will be 2816 flowers after six weeks.

The student is asking about a pattern of growth in the population of wildflowers. The flowers began blooming with 88 blooms and by the second week, there were 176 flowers in bloom. This indicates that the number of flowers is doubling each week. To find the number of flowers after six weeks, we can establish a pattern of growth and calculate the number for the sixth week.

We can see that from week 1 to week 2, the blooms doubled (88 x 2 = 176). If this pattern continues, the blooms will double each week.

Let's calculate the number of blooms for each week up to six weeks:

Week 1: 88 flowers

Week 2: 176 flowers (88 x 2)

Week 3: 352 flowers (176 x 2)

Week 4: 704 flowers (352 x 2)

Week 5: 1408 flowers (704 x 2)

Week 6: 2816 flowers (1408 x 2)

math class has 6 girls and 2 boys in the seventh grade and 3 girls and five boys in the right grade. the teacher randomly selects a 7th and a 8th grader. What is the probability that the student she selects are both girls

Answers

Final answer:

To find the probability of selecting two girls, multiply the probability of selecting a girl from the 7th grade class by the probability of selecting a girl from the 8th grade class.

Explanation:

To find the probability that the teacher selects two girls, we need to determine the probability of selecting a girl from the 7th grade class and the probability of selecting a girl from the 8th grade class, and then multiply those probabilities together.

Probability of selecting a girl from the 7th grade class = Number of girls in 7th grade class / Total number of students in 7th grade class = 6 / (6+2) = 6/8 = 3/4 = 0.75

Probability of selecting a girl from the 8th grade class = Number of girls in 8th grade class / Total number of students in 8th grade class = 3 / (3+5) = 3/8 = 0.375

Probability of selecting two girls = Probability of selecting a girl from 7th grade class * Probability of selecting a girl from 8th grade class = 0.75 * 0.375 = 0.28125

Final answer:

The probability of selecting two girls, one from each grade, is 9/32.

Explanation:

The probability of selecting a girl from the seventh-grade class is 6/8, since there are 6 girls out of 8 total students. Similarly, the probability of selecting a girl from the eighth-grade class is 3/8. Since the two events are independent of each other, we can multiply the probabilities to find the probability of selecting a girl from both grades.

So, the probability of selecting a girl from the seventh grade AND a girl from the eighth grade is (6/8) * (3/8) = 18/64 = 9/32.

Therefore, the probability that the teacher selects two girls is 9/32.

If the endpoints of the diameter of a circle are (−10, −8) and (−6, −2), what is the standard form equation of the circle?

Answers

Final answer:

The standard form equation of the circle with endpoints (-10, -8) and (-6, -2) is (x + 8)^2 + (y + 5)^2 = 13.

Explanation:

To find the standard form equation of a circle, we need to find the center and the radius. Since the endpoints of the diameter are given, we can find the center by finding the midpoint of the diameter. The x-coordinate of the center is the average of the x-coordinates of the endpoints, and the y-coordinate of the center is the average of the y-coordinates of the endpoints. The radius is half the length of the diameter. Once we have the center and radius, we can plug them into the standard form equation of a circle, which is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.

Step 1: Find the midpoint of the diameter using the formula:
(x, y) = ((x1 + x2) / 2, (y1 + y2) / 2)
(x, y) = ((-10 + -6) / 2, (-8 + -2) / 2) = (-16 / 2, -10 / 2) = (-8, -5)

Step 2: Find the radius by halving the length of the diameter:
Length of the diameter = √((x2 - x1)^2 + (y2 - y1)^2) = √((-6 - -10)^2 + (-2 - -8)^2) = √(16 + 36) = √(52)
Radius = √(52) / 2 = √(13)

Step 3: Plug the center and radius into the standard form equation of a circle:
(x + 8)^2 + (y + 5)^2 = 13

a cell phone company has a basic monthly plan of $40plus $0.45 for many minutes ised over 700. John was charged a total of $48.10. Write an equation to determine how many minutes he must have used during the month.

Answers

Cost of month plan = $40

Cost of minutes used = $0.45 after 700 minutes

Total cost = $48.10

Let x be the total minutes used
Total cost = 40 + 0.45(x - 700)

------------------------------------------------------------------
Form the equation and solve x
------------------------------------------------------------------
40 + 0.45(x - 700) = 48.10
40 + 0.45x - 315 = 48.10
0.45x - 275 = 48.10
