Answer:

A. 3:4

B. 63 soccer players

Step-by-step explanation:

A. If out of 7 players, 3 wore headbands, then it means 4 out of 7 did not wear headbands.

Ratio of players who wire headbands to those who didn't wear headbands would be 3:4

B. Let x represent number of players who wore headbands

Number of players who didn't wear = 36

Total number of players in the league = number of players who wore headbands + those who didn't wear headbands = x + 36

Let's find x by using the ratio generated in part A.

Ratio of players who wore head bands to players who didn't wear = 3:4 = x:36

[tex] \frac{3}{4} = \frac{x}{36} [/tex]

Cross multiply

[tex] 4*x = 3*36 [/tex]

[tex] 4x = 108 [/tex]

[tex] \frac{4x}{4} = \frac{108}{4} [/tex]

[tex] x = 27 [/tex]

Total number of players in the league = x + 36

Plug in the value of x

= 27 + 36

= 63 players

I have had the question in the past

Answer:

15a: 3 tarts = 90 minutes or 1 tart = 30 minutes

15b: 3.75 days

15c: 5 = 120 minutes or 1 tart every 24 minutes. It would take 720 minutes, or 12 hours, and if Peter is working 4 hrs a day, it would take 3 days.

Answer:

[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{4^{1}}{4^{3}}[/tex]

[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{1}{4^{2}}[/tex]

Step-by-step explanation:

Given

[tex]\dfrac{4^{-3}}{4^{-1}}[/tex]

Required

Choose equivalent expressions

Choosing the first answer:

[tex]\dfrac{4^{-3}}{4^{-1}}[/tex]

Split expressions

[tex]4^{-3} * \frac{1}{4^{-1}}[/tex]

Apply laws of indices: [tex](a^{-b} = \frac{1}{a^b})[/tex]

[tex]\frac{1}{4^3} * \frac{1}{4^{-1}}[/tex]

Apply laws of indices: [tex](a^{-b} = \frac{1}{a^b})[/tex]

[tex]\frac{1}{4^3} * \frac{1}{1/4}[/tex]

[tex]\frac{1}{4^3} * \frac{4^1}{1}[/tex]

[tex]\frac{4^1}{4^3}[/tex]

Hence:

[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{4^{1}}{4^{3}}[/tex]

Choosing the second:

[tex]\dfrac{4^{-3}}{4^{-1}}[/tex]

Apply law of indices: [tex](\frac{a^m}{a^n} = a^{m-n})[/tex]

So,

[tex]\dfrac{4^{-3}}{4^{-1}} = 4^{-3-(-1)}[/tex]

[tex]\dfrac{4^{-3}}{4^{-1}} = 4^{-3+1)}[/tex]

[tex]\dfrac{4^{-3}}{4^{-1}} = 4^{-2}[/tex]

Apply law of indices: [tex](a^{-b} = \frac{1}{a^b})[/tex]

So:

[tex]\dfrac{4^{-3}}{4^{-1}} = \dfrac{1}{4^{2}}[/tex]

Answer: 10-7x3+18

Step-by-step explanation:

Ten less so that would be (10-) less than seven would make it (10-7) times a number is the same as 3 would make it (10-7x3) plus 18 would then make it (10-7x3+18)

Did that help??!!

You would want to use the Keep, Change , Flip

method. So you keep the 1/8, change division into multiplication, the flip the 4 into 1/4.

Hi there !

n = - 27/3

n = - 9

Good luck !

Answer:

125 times bigger.

Step-by-step explanation:

A great way to visualize this problem is to think of it as a volume problem itself. Another good way to think about it is to plug in numbers in its place.

Way #1

5*5*5 (or 5^3)=125

Way #2

(2*2*2)=8

(2*5)*(2*5)*(2*5)=1000

1000/8=125

Answer:

y<-2/3x. y< x-3

Step-by-step explanation:

y ≤ - (2/3)x and y < x - 3 are the system of inequalities that best matches he graph below.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

First, we can see that for both of the inequalities the shaded part is below the lines.

You also can see that the solid line (correspondent to the symbol ≤) is the one with a negative slope, and the dashed line (correspondent with the line <) is the one with a positive slope.

Only with that, we conclude that the correct option is B.

y ≤ - (2/3)x

y < x - 3

Hence, y ≤ - (2/3)x and y < x - 3 are the system of inequalities that best matches he graph below.

Correct arrangement of the question is;

Rewrite the rational exponent as a radical: five to the three fourths power all raised to the two thirds power

A) the cube root of 5 squared

B) the twelfth root of 5

C) the square root of 5

D) the cube root of 5 the fourth power

Answer:

Option C) the square root of 5

Step-by-step explanation:

We are given: five to the three fourths power all raised to the two thirds power

Translating that statement means 5 is raised to ¾ raised to ⅔.

In indices, when we have two powers attached to a number, the two powers will multiply each other.

Thus, 5 is raised to; ⅔ × ¾ = 2/4 = ½

Thus, 5 is raised to power ½.

Now, when a number is raised to the power ½, it is said to be square root of that number.

Thus, the right answer is square root of five.

Answer:

y=3/4x+7

Step-by-step explanation:

You want to find the equation for a line that passes through the point (-4,4) and has a slope of 3/4.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was 3/4. So you can right away fill in the equation for a line somewhat to read:

y=3/4x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(-4,4). When x of the line is -4, y of the line must be 4.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the 3/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,4).

So, why not plug in for x the number -4 and for y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!.

(-4,4). y=mx+b or 4=3/4 × -4+b, or solving for b: b=4-(3/4)(-4). b=7.

Answer:

Step-by-step explanation:

1. Let the number be x

x^2 + 4x = 21

x^2 + 4x - 21 = 0

Solve the quadratic equation using factorization method

x^2 - 3x + 7x - 21 = 0

x(x - 3) + 7(x - 3) = 0

(x - 3)(x+7) = 0

x - 3 = 0 x + 7 = 0

x = 3 x = -7

The number is either 3 or -7

2. Same solution as number 1

3. Let

Width = x

Length = 2x - 3

Area of the rectangle = 9 square ft

Area of a rectangle = length × width

9 = (2x - 3) (x)

9 = 2x^2 - 3x

2x^2 - 3x - 9 = 0

Solve using quadratic formula

a = 2

b = -3

c = -9

x = -b +or- √b^2 - 4ac / 2a

= -(-3) +or- √(-3)^2 - 4(2)(-9) / 2(2)

= 3 +or- √ 9 - (-72) / 4

= 3 +or- √9 + 72 / 4

= 3 +or- √81 / 4

= 3 +or- 9 / 4

x = (3 + 9)/4 or (3 - 9) / 4

= 12 / 4 or -6 / 4

x = 3 or -3/2

Width can not be a negative value

So,

Width = x = 3 ft

Length = 2x - 3

= 2(3) - 3

= 6 - 3

= 3ft

2.if the sum of the square of the number and 4 time that number is 21 the what is the number?

3. the length of the rectangle is 3 less than twice the width. if the area is 9 square ft, the length and width of the rectangle.

4.given the figure below. find the area of the shaded part of the rectangle if the area of the big but angle is 6 times the area of the unshaded rectangle ​

Unshaded area

Length = 2x

Width = x

Shaded area

Length = (2x+3)

Width = (x+3)

Area of the shaded area = 6 × the unshaded area

(2x) (x) = 6(2x + 3)(x+3)

2x^2 = 6(2x^2 + 6x + 3x + 9)

2x^2 = 12x^2 + 36x + 9x + 54

2x^2 = 12x^2 + 45x + 54

12x^2 + 45x + 54 - 2x^2 = 0

10x^2 + 45x + 54 = 0
