Answer:

y = 15

Step-by-step explanation:

We need to solve for k

y = x

21 = 7k  Divide both sides by 7 to solve for k

3 = k

y = xk

y = 5(3)

y = 15

Answer: y = 15

7 x 9 = 63

Step-by-step explanation:

Answer: 1. Using the line test, the function runs into the same x-values; so this is not a linear function. 2. A linear function can't have different y-values with the same x-value; so this is not a linear function.

Answer:

\(\sqrt[4]{625x^{12}y^8} = 5 {x^3} {y^2}\)

Step-by-step explanation:

Given

\(\sqrt[4]{625x^{12}y^8}\)

Required

Simplify

We start by splitting the roots

\(\sqrt[4]{625x^{12}y^8} = \sqrt[4]{625}* \sqrt[4]{x^{12}} * \sqrt[4]{y^8}\)

Express 625 as exponents

\(\sqrt[4]{625x^{12}y^8} = \sqrt[4]{5^4}* \sqrt[4]{x^{12}} * \sqrt[4]{y^8}\)

From laws of indices

\(\sqrt[n]{a^m} = a^{\frac{m}{n}}\)

So,

\(\sqrt[4]{625x^{12}y^8} = \sqrt[4]{5^4}* \sqrt[4]{x^{12}} * \sqrt[4]{y^8}\) becomes

\(\sqrt[4]{625x^{12}y^8} = {5^\frac{4}{4}} * {x^\frac{12}{4}} * {y^\frac{8}{4}}\)

\(\sqrt[4]{625x^{12}y^8} = 5 * {x^3} * {y^2}\)

\(\sqrt[4]{625x^{12}y^8} = 5 {x^3} {y^2}\)

Answer : 5 players

Step - by - step explanation :

First, put the information down . . .

1 out 3 players are new this season

there are 15 players in total

Second, convert ( the denominator [ to 15 ] ) . . .

1/3 x 5/5 = 5/15 <-- 5 players are new this season

tip : when trying to do things like this - multiply the numerator and the denominator by the same number for accurate results !

The number of new players is 5.

Division is breaking a number up into an equal number of parts.

Given that, One out of every 3 players on a soccer team is new this season, There are 15 players on the team in all.

15/3 = 5

Hence, The number of new players is 5.

Answer:

Step-by-step explanation:

Let's start by finding the sum of the list of nine numbers, which we can then use to find the value of the remaining two numbers in the list:

Sum of the nine numbers = mean * number of numbers = 17 * 9 = 153

Let the three modes be a, b, and c. Since they are modes, each of them must appear at least twice in the list.

Let's assume that the numbers in the list are arranged in non-decreasing order. Then we have:

a ≤ b ≤ c

Since a, b, and c are modes, each of them must appear at least twice in the list. We have three cases to consider:

Case 1: Each of a, b, and c appears exactly twice in the list.

In this case, the remaining three numbers in the list are:

x1 = a + 4

x2 = b + 1

x3 = c - 8

We know that x1, x2, and x3 are distinct and not modes of the list. Therefore, they must be among the six numbers in the list that are not equal to a, b, or c. Let's call these numbers d, e, and f, where:

d ≤ e ≤ f

Then we have:

a + b + c + x1 + x2 + x3 + d + e + f = 153

3(a + b + c) + 3(d + e + f) = 153 + x1 + x2 + x3

Since x1, x2, and x3 are distinct and not modes of the list, we have:

x1 > c

x2 > b

x3 < c

Therefore, we can write:

x1 = c + k1

x2 = b + k2

x3 = a + k3

where k1, k2, and k3 are positive integers.

Substituting these expressions into the equation above, we get:

3(a + b + c) + 3(d + e + f) = 153 + a + b + c + k1 + k2 + k3

Simplifying, we get:

2(a + b + c) + 3(d + e + f) = 153 + k1 + k2 + k3

Since k1, k2, and k3 are positive integers, the right-hand side of this equation is at least 3. Therefore, we have:

2(a + b + c) + 3(d + e + f) ≥ 156

We want to find the value of 3(a + b + c), so let's isolate this term:

3(a + b + c) = 2(a + b + c) + (a + b + c)

Since the left-hand side is three times the sum of a, b, and c, and the right-hand side involves the sum of a, b, c, d, e, and f, we need to express d, e, and f in terms of a, b, and c.

From the inequality a ≤ b ≤ c, we have:

a + k3 ≤ b + k2 ≤ c + k1

Adding 4 to the first inequality, we get:

a + k3 + 4 ≤ b + k2 + 4 ≤ c + k1 + 4

Adding -8 to the second inequality, we get:

a + k3 + 4 ≤ c + k1 - 4 ≤ b + k2

Therefore, we can choose d = a + k3 + 4, e = c + k1 - 4, and f = b + k2. Then

Answer:

X = 35° & Y= 110°

Step-by-step explanation:

The total measure of all angles in a parallelogram must equal to 360°. While finding the measures, it is important to remember that opposite angles of parallelograms are congruent & adjacent angles of parallelograms are supplementary.

Let's call (3x+5): Side A

Side B: 70°

Side C: 2x

Side D: (x+3y)

Opposite angles of parallelograms are congruent, which means:

Side C = Side B

Side A = Side D

Lets solve for X:

Since side B = Side C, we can divide: 70°/2x

This means that X=35°

Lets solve for Y:

We already know the value of x. So lets substitute it into side a.

(3x+5)°

= (3(35)+5)

= (105+5)

= 110° ans

Now we know that side D must equal to 110°.

Side D= (x+3y)

(35+3y) = 110°

Subtract 35 on both sides, which gives you 3y= 75°

Now we divide both sides by 3, and this gives us 25°.

Y=25°

To check if the values of x & y are correct, we can add all the values and make sure they add up to 360°.

Side A + Side B + Side C + Side = 360°

110 + 70 + 70 + 110 = 360°

= 360° = 360°

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

Answer:

The required height of the lighthouse is given as 160 ft tall.

Given that,

A scale model of a lighthouse has a scale of 1 in. : 8 ft. The scale model is 20 inches tall.

What is the scale factor?

The scale factor is defined as the ratio of the modified change in length to the original length.

What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

here,

scale factor = 1 / 8 in per ft

Now,

The actual length of the lighthouse =  20 / [1 / 8]

                                                            = 20 × 8 = 160 ft

Thus, the required height of the lighthouse is given as 160 ft tall.
