What is 6x^2 – 3х + 12 =

Final answer:

To find three ratios equivalent to 3:12, we simplify the ratio to 1:4 and then scale it up. The three equivalent ratios are 2:8, 3:12 (the original ratio), and 4:16.

Explanation:

To find three ratios equivalent to the ratio 3:12, we need to simplify or scale the given ratio up or down. Given that 3:12 simplifies to 1:4 (by dividing both numbers by their greatest common divisor, which is 3), any multiple of this simplified ratio will also be equivalent to 3:12.

These three equivalent ratios show the concept of scaling a ratio up while maintaining the proportional relationship between the two quantities.

Answer:

  c.)  π/4

Step-by-step explanation:

Form the desired ratio and simplify:

  A / B = circle area / square area

  = (36π)/(144) = (π·36)/(4·36) = π/4 . . . . matches choice C

The answer to this question is C.

The y-intercept of a graph is the point, where the graph crosses the y-axis.

The graph with the given details is graph (c)

The given parameters are:

[tex]\mathbf{Domain = (-\infty,4)\ u\ (-4,3)\ u\ (3,\infty)}[/tex]

[tex]\mathbf{y-intercept = (0,3)}[/tex]

[tex]\mathbf{Increasing\ interval = (0,4)}[/tex]

From the list of given options. graph (d) has a y intercept of 2, because it crossed the y-axis at y = 2.

So, graph (d) cannot be the required graph

Graph (a) has a domain of: [tex]\mathbf{(-\infty,5),,,,,}[/tex]

So, graph (a) cannot be the required graph

The domain of graph (b) is [-3,3]

So, graph (b) cannot be the required graph

Hence, the required graph is graph (c)

1 foot and a half lol

Step-by-step explanation:

step

by

step

The objects which are more than 1 foot but less than 2 feet are of the measurements 1.1 feet, 1.2 feet, 1.25 feet, and so on.

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is essential to determine the quantity of any object.

Given that,

We have to find the object which has the length of more than 1 foot but less than 2 feet.

Those objects will be having the measurements in between 1 foot and 2 feet.

1 foot is approximately 30.5 cm.

So, the object will be having the length of 30.5 cm to 61 cm.

Hence the required objects will be having the length in between 30.5 cm to 61 cm.

Answer:

2 miles per day

Step-by-step explanation:

The length of the road built is 1/3 miles, so let's call L = 1/3

The time spent to build this length is 1/6 days, so let's call D = 1/6

To find the unit rate in miles per day, that is, the speed that this length of the road was built, we just need to divide L by D (speed is distance over time). Let's call the speed S:

S = D/T

S = (1/3) / (1/6)

S = (1/3) * 6

S = 2 miles per day

The unit rate, which is the rate of distance built per day, is 2 miles per day. Calculated by dividing the total distance by the total time, multiplying 1/3 by the reciprocal of 1/6.

This question involves the concept of unit rates. A unit rate tells us how one quantity relates to one unit of another quantity. In this case, we are asked to find the number of miles of road that can be built in one day (the unit rate).

To find the unit rate, we need to divide the total distance (1/3 miles) by the total time (1/6 days). When we divide fractions, we multiply the first fraction by the reciprocal of the second.

So, the calculation should be (1/3) ÷ (1/6) = (1/3) * (6/1) = 2.

So, the construction crew can build 2 miles of road in one day.

Answer:

x = 19

y = 14

so c is the correct answer

Step-by-step explanation:

for them to be parallel, 5x + 15 has to equal 110 because of the 70 on the opp side making the two supplementary, and 5y has to equal 70

so 5y = 70, making y = 14

then 5x + 15 = 110

Answer:

ok so the earth radius is 1534mi so if that is the radius than the area is 7.39×10^6so then you divide that into 3 pieces so each piece would be 2,463,333.3333 the nearest million would be 2,000,000

Step-by-step explanation:

To find the land area of a planet with a radius of approximately 1,534 miles and two-thirds water coverage, we calculate the total surface area and take one-third of that as the land area. The land area is approximately 9,867,658 square miles, which rounds to 10 million square miles.

To estimate the land area on the planet with a radius of 1,534 miles that is two-thirds covered by water, we first calculate the planet's total surface area using the formula for the surface area of a sphere, which is 4πr². Plugging in the radius:

Total surface area = 4π(1,534)² ≈ 29,602,975 square miles.

Since two-thirds of the planet's surface is covered by water, one-third is land. Therefore, the land area is approximately:

Land area = ([tex]\frac{1}{3}[/tex]) × Total surface area ≈ ([tex]\frac{1}{3}[/tex]) × 29,602,975 ≈ 9,867,658 square miles.

When rounded to the nearest million, the estimate for the land area is 10 million square miles.

Answer:

10

Step-by-step explanation:

Don't just think: 6,7,8,9, oh it must be 10.

When x is 0, y is 6. That means no matter what 6 is added to x. So if we look at when x is 2, y = 8. Lets subtract the 6 from the 8 and we get 2. So the x is not multiplied by anything.

The equation is y = x+6.

Answer:

Step-by-step explanation:

Median means the middle number. So you can look at it like this:

a,b, 20, c,d

Those are the variables for the numbers we do not know. We do know that they are all even numbers and they are consecutive, meaning in sequence. So if they are all even, then there should be a gap of 2 between each. They should also be in order. Knowing that, you can subtract 2 from 20 to get b, subtract 2 from b to get a, add 2 to 20 to get c, and add 2 to c to get d.

This should be your answer:

16, 18, 20, 22, 24

Consecutive, and even.

Final answer:

The smallest integer in the set of five consecutive even integers with a median of 20 is 16. This is calculated by recognizing the median as the middle value, and subtracting 4 (for two even steps) from the median.

Explanation:

If the median of five consecutive even integers is 20, we can determine the value of the smallest integer by understanding the property of consecutive even numbers and the nature of the median in a symmetrically distributed set. Since the median of this set is the middle value, the five consecutive even numbers can be represented as:

x

x + 2

20 (the median)

x + 4

x + 6

The median, 20, is the third value in this ordered set. To find the smallest value, x, we look two even numbers behind 20. Since consecutive even numbers increase by 2 with each step, we subtract 4 from 20 to find the smallest value.

20 - 4 = 16

Therefore, the smallest integer in this set of five consecutive even numbers is 16.

Final answer:

There is no integer power of 7 that exactly equals 2041, as 7 to the power of 4 is 2401, which is the closest integer power of 7 that is higher than 2041.

Explanation:

The question asks to determine the power of 7 that equals 2041, which is written mathematically as 2041 = 7x. To solve this, one approach is to estimate and refine by trying different powers of 7 until we get close to 2041. Here's how the estimation process could work:

Start with lower powers of 7 like 72 = 49, and increase the exponent.

Notice that 73 = 343 and 74 = 2401.

Since 2401 is just above 2041, we suspect our answer will be close to 4 but slightly less.

Checking with a calculator or using a division strategy, we can confirm that 2041 is slightly below 74, making it clear there's no integer power of 7 that equals 2041.

Therefore, there isn't an integer power of 7 that precisely equals 2041.

Answer:

Part A: 204 pages

Step-by-step explanation:

Eliza reads of her book on Monday by [tex]\frac{r}{7}[/tex] pages, where r is the total number of pages in the book.

On Tuesday and Wednesday combined,  she reads three times as much as she reads on Monday i.e. [tex]\frac{r}{7} * 3 = \frac{3r}{7}[/tex] pages.

So, combining Monday, Tuesday and Wednesday she reads [tex]( \frac{r}{7} + \frac{3r}{7} ) = \frac{4r}{7}[/tex] number of pages.

Part A: If Eliza's book has a total of 357 pages then combining Monday, Tuesday and Wednesday she reads [tex]\frac{4*357}{7} = 204[/tex] pages.
