Mia is three years older than twice her sister Brooke's age. The sum of their ages is less than 30. What is the greatest age brook can be ?

Answers

Answer 1
Whenever you see the phrases "less" or "greater," it's usually a pretty good indicator that you're going to be dealing with inequalities in some way or another.

As with most word problems, our "setup" should involve first giving a label to our unknowns. We don't know what Brooke's age is, so let's label that with the variable b. We know that Mia is three years older than twice Brooke's age, which, using our new variable, can be modeled with the expression m = 2b + 3, where the variable m represents Mia's age.

We're also given that the sum of their ages is less than 30, or, translated into an inequality:

[tex]m+b < 30[/tex]

We already know that m = 2b + 3 though, so we can rewrite everything in terms of Brooke's age, b:

[tex](2b + 3)+b < 30[/tex]

From there, simply solve for b and you'll have your upper limit.

Sylvia walked​ 3/4 ​mi east from her house to the bank. Then she walked 1/3 ​mi west to a gift shop. From the gift shop, she walked​ 1/4 ​mi west to a grocery store. How far is the grocery store from Sylvia's house?

Answers

Solution:

The grocery store is 1/6 miles far from her house.

Explanation:

We have been given that Sylvia walked​ 3/4 ​mi east from her house to the bank. Hence, the distance between the house and the bank is 3/4 miles.

Now, she walked 1/3 ​mi west to a gift shop. It means that she moved 1/3 miles towards her house.

Also,  from the gift shop, she walked​ 1/4 ​mi west to a grocery store. It means she moved 1/3 miles plus 1/4 miles towards her house.

Hence, the distance between the grocery store and the house is

[tex]\frac{3}{4}-\left ( \frac{1}{3}+\frac{1}{4} \right )\\\\=\frac{3}{4}-\frac{1}{3}-\frac{1}{4} \\\\ =\frac{1}{6}[/tex]

The expression 0.09x+(x−30) models the final price of a bicycle with an instant rebate in a state that charges a sales tax. The tax is on the original price. Which expression represents the amount of tax that is paid on the bicycle?

A) 1.09x

B) 0.09x

C) 0.09x - 30

D) x - 30

Answers

The correct answer is option B). The expression that represents the amount of tax paid on the bicycle is 0.09x.

The expression given is:

[tex]\[ 0.09x + (x - 30) \][/tex]

This expression can be broken down into two parts:

1. [tex]\( 0.09x \)[/tex] represents the tax paid on the original price of the bicycle, where [tex]\( x \)[/tex] is the original price and [tex]\( 0.09 \)[/tex] (or [tex]\( 9\% \)[/tex]) is the tax rate.

2. [tex]\( (x - 30) \)[/tex] represents the final price after the instant rebate of $30 has been subtracted from the original price [tex]\( x \)[/tex].

Since we are looking for the amount of tax paid, we only need to consider the tax component, which is [tex]\( 0.09x \)[/tex].

Therefore, the expression that represents the amount of tax paid on the bicycle is: [tex]{0.09x}[/tex]

The entire large rectangle above is 38 units long and 2 units wide.
Its area is length times width, so the area is 2 * 38.
38 is also the same as 30 + 8, so the area can also be written as 2(30 + 8).

The left rectangle is 30 units long and 2 units wide. Its area is 2 * 30.
The right rectangle is 2 units long and 8 units wide. Its area is 2 * 8.

If you add the areas of the small rectangles, you get
2 * 30 + 2 * 8

If you add the two small areas, you get the area of the laerge rectangle, so

2(30 + 8) = 2 * 30 + 2 * 8

which is an example of the distributive property.

The Pythagorean Sea, in Southern Antarctica has a depth that varies quadratically with its width. The width of the sea is 1000 meters. Two hundred meters from shore, the depth is 20 meters. Find the particular quadratic equation for the sea. Compute the depth of the deepest portion of the sea.

Answers

Final answer:

To find the quadratic equation that models the depth of the Pythagorean Sea, we apply given conditions to the standard form y = ax^2 + bx + c. Solving for coefficients, we then identify the vertex of the parabola to find the deepest point of the sea. Finally, we calculate the depth at this point by substituting the vertex into the equation.

Explanation:

Finding the Particular Quadratic Equation and Depth of the Sea

To find the particular quadratic equation for the depth of the Pythagorean Sea as a function of its width, we can begin by assuming the standard form of the equation:

y = ax^2 + bx + c,

where y represents the depth in meters, and x is the horizontal distance from the shore in meters. Given that the sea's width is 1000 meters and at 200 meters from the shore the depth is 20 meters, we can establish some conditions.

At x = 0 (shoreline), the depth is 0: hence, c = 0.At x = 200 meters, the depth is y = 20 meters.At x = 1000 meters (opposite shoreline), the depth should return to 0.

By substituting these conditions into the equation, we can solve for a and b to determine the complete equation. Once we have the equation, the depth's maximum (the deepest part of the sea) will occur at the vertex of the parabola, which is at x = -b/(2a).

Once we find the deepest point, we can calculate its depth by substituting back into the equation.

Answer:

equation: y = 0.0005x²

maximum depth: 500 m

Step-by-step explanation:

Equation for a quantity that changes quadratically with another quantity:

y = kx²

where x = width, and y = depth.

For x = 200, y = 20.

20 = k(200²)

k = 20/(40000)

k = 0.0005

The equation is

y = 0.0005x²

The width is 1000 m.

For 1000 m, x = 1000

y = 0.0005x²

y = 0.0005(1000²)

y = 500

Answer:

equation: y = 0.0005x²

maximum depth: 500 m

 so 6/2 = 3 balls of wool are needed.

4/8 = x/6

8x/24

x = 24/8 = 3

Malcom will need 3 balls of wool to make 6 caps.

Understanding Wool to Caps Ratio

To determine how many balls of wool Malcom will need to make 6 caps, we will use a ratio table. We know that 4 balls of wool can make 8 knitted caps. We can set up a ratio table to find the number of balls needed for any number of caps.

Step-by-Step Explanation:

Step 1: Establish the known ratio: 4 balls of wool : 8 caps

Step 2: Simplify the ratio: (4 balls of wool) / (8 caps) = 1 ball of wool : 2 caps

Step 3: Determine the number of balls of wool needed for 6 caps using the simplified ratio. If 1 ball of wool makes 2 caps, then:

Step 4: Calculate: (number of caps) / (caps per ball) = 6 caps / 2 caps per ball = 3 balls of wool

Therefore, Malcom will need 3 balls of wool to make 6 caps.

One of the greatest baseball hitters of all time has a career batting average

of 0.366. Is it a statistic or a parameter


Answers

Its a statistic , because it the stat of the average batting . I don't think its correct thought . So sorry if I am not correct .

Final answer:

The career batting average of 0.366 for a baseball player is a parameter, whereas the 50 percent of high school seniors planning to attend college in a survey is a statistic.

Explanation:

The career batting average of 0.366 for one of the greatest baseball hitters of all time is a parameter, because it represents a numerical characteristic of the entire population of interest, which in this case is the player's hits during his career. A parameter is an actual value from the population, whereas a statistic is a value calculated from a sample that estimates a parameter. In baseball statistics, a player's career average is calculated using all of his at-bats and hits across his career, representing the whole population of his at-bats, hence being a parameter.

In the situation described in option 7 of the provided information, the 50 percent that indicates the proportion of high school seniors planning to attend a four-year college or university the following year is a statistic. This is because it is likely derived from a sample of the overall population of high school seniors, rather than including all high school seniors across the country.

Answers

Let's just say that:
B = Bucket
J = Jar.

The amount of water J can hold is 8 liters less than B. So:
J = C - 8
(C represent the amount of water the bucket can hold)

And let's do the same for B. Since B holds C amount of water, the expression for this is:
B = C

Hope I answered your question!

Answer:

The answer is:

The bucket may hold [tex]\frac{C}{C-8}[/tex] times the amount of water of the jar.

Step-by-step explanation:

In order to determine the answer, we have to know about proportion.

When we use proportion, we want to express a fraction between two measures. It is useful to compare each other if something is more than twice or three times or whatever.

In this case, we have two measures.

C= amount of water that is holded by the bucket.

J=amount of water that is holded by the jar.

Where:

[tex]C=J+8[/tex]

So, expressing both measure as a proportion:

[tex]\frac{C}{J}=\frac{C}{C-8}[/tex]

Finally, the bucket may hold [tex]\frac{C}{C-8}[/tex] times the amount of water of the jar.
