Answer:

180

Step-by-step explanation:

So, in the first 4 games, they score 10 points. If this continues to happen in the remaining 18 games, it would be 180.

             10 x 18 = 180.

1)  A number that is divided by 5, with the result as 50 less than if the number had been divided by 6 is; -1500

2) If both turtles survive until then, the number of years from today that the older turtle's age would be 3 times that of the younger turtle is; 146 years

1) Let the number be x. We are told that it is divided by 5, and the result is 50 less than if the number had been divided by 6. Thus, we have;

(x/6) - (x/5) = 50

Multiply through by 30 to get;

5x - 6x = 1500

-x = 1500

x = -1500

2) Let the older turtle be x and the younger one be y.

Today, the older turtle's age is 11 times that of the younger turtle. Thus;

Todays age;

Older turtle = 11y years

Younger turtle = y years

In 24 years, the older turtle's age will only be 7 times that of the younger turtle. Thus;

11y + 24 = 7(y + 24)

11y + 24 = 7y + 168

11y - 7y = 168 - 24

4y = 144

y = 144/4

y = 36

Thus;

Age of older turtle today = 11 * 36 = 396 years

Age of younger turtle today = 36 years

Thus, for older turtle to be thrice the age of younger turtle, then;

3(36 + t) = 396 + t

108 + 3t = 396 + t

2t = 292

t = 292/2

t = 146 years

8/9 - 1/3

To subtract these two fractions, first find a common denominator.

The common denominator will be the

least common multiple for the two denominators.

In this case, the least common multiple of 9 and 3 is 9.

So to subtract, a denominator of 9 is needed in each fraction.

8/9 already has 9 in the denominator so it stays the same.

To get a 9 in the denominator of 1/3, multiply top and bottom by 3.

This gives us 3/9.

So we have 8/9 - 3/9 which is 5/9.

Answer: i believe its 0.46 im not for sure though

Step-by-step explanation:

The order of the numbers from lowest to highest is 4.68 × 10⁻⁶,  8.34 × 10⁻², 1.2  × 10⁷, 3.24 × 10⁹ and  5.48  × 10⁹

The given numbers are expressed in standard form. Standard form is a way of writing numbers as a power 10 e.g 100 = 1 × 10² and 0.01 = 1 × 10⁻².

So converting the numbers back to ordinary numbers will be useful.

To do this, we will multiply or divide the powers of 10 with the decimal numbers.

We will multiply if the power is positive e.g 2.4 x 10² = 2.4 x 100 = 240 and divide if the power is negative  2.4 x 10⁻² = 2.4/100 = 0.024

3.24 × 10⁹  = 3.24 x 1000,000,000 =  3240000000

4.68 × 10⁻⁶ = 4.68 / 1000000 = 0.00000468

5.48  × 10⁹ = 5480000000

8.34 × 10⁻² = 8.34/100 = 0.0834

1.2  × 10⁷ = 12000000

Therefore, arranging from lowest to highest. We have:

4.68 × 10⁻⁶,   8.34 × 10⁻², 1.2  × 10⁷, 3.24 × 10⁹ and  5.48  × 10⁹

There is a 0.0530 percent probability that the randomly chosen study participant will be shorter than 68 inches.

The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance.  Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

We have been given that

μ = 68.3

σ = 4.0

Find the probability that a study participant has a height that is less than 68 inches.

We are supposed to find P(x<68)

x = 68

z = (x - μ) / σ

z = (68 - 68.3) / 4

z = -0.3 / 4

z = -0.075

Use z table :

So, P(z<-0.0725)=0.0530

Answer:

f(x) = x^4

Step-by-step explanation:

h(x) = f(g(x)) = (x - 2)^4

g(x) = x - 2

h(x) = f(g(x)) = (g(x))^4

f(x) = x^4

The length , width and height of a box with volume 125 cubic centimeters will be

1, 5 and 25.

The volume of a box can be calculated by multiplying its length, width, and height.

here given volume = 125

V = l x w x h

125 = l x w x h

l, w, h is the factors of 125

To find the common factors, we must first list the factors of each of the given numbers.

since 125 is  composite number, it will have more than two factors.

125 → 1, 5, 25 and 125.

The factors of 125 is 1, 5, 25,125

here 125 cannot consider as length since volume is 125 other sides cannot be 0.

so the length, width, height can be 1 , 5, 25.

Marcus have 44 CDs, Sherry have 34 CDs and Kristen have 22 CDs.

Let us assume that Kristen has x numbers of CD's.

According to the provided situation,

Marcus have twice the number of CDs as Kristen.

Number of CDs of Marcus = 2x

The number of CDs of Sherry is 12 more than the CDs of Kristen

Number of CDs of of Sherry = 12 + x

Total number of CDs combined are 100.

So, we can write,

x + 2x + (12 + x) = 100

4x + 12 = 100

Any equation with the highest degree of variable as one, just like the above equation is called Linear Equation.

Further solving the Equation,

4x + 12 = 100

4x = 88

x = 22

The number of CDs that Kristen has is 22.

The number of CDs that Marcus have is 2(22).

The number of CDs Marcus gas is 44.

The number of CDs Sherry has is (12 + x) which is equal to 34.

The number of CDs Kristen, Marcus and Sherry have is 22, 44 and 34 respectively.

Solution

Step 1

Two lines are perpendicular if the product of their slope = -1

Step 2

Step 2

In any equation in math, the most basic thing is the the fact that both expressions on either side of the equality sign are of the same value. This means -35 and 5b (in number 1) are of the same value. Therefore, whatever you do to the one on the left, you must likewise do to the one on the right. That is, if you have to add 10 to the one on the left, you must simultaneously add 10 to the one on the right. Hence, number 1 is solved as follows;

(1) -35 = 5b

To eliminate the 5 and isolate the b variable, divide both sides by 5

-35/5 = 5b/5

- 7 = b

(2) x - 6 = - 26

Add 6 to both sides of the equation;

x - 6 + 6 = - 26 + 6

x = - 20

(3) 130 = 13b

Divide both sides of the equation by 13

130/13 = 13b/13

10 = b

(4) 19 = 16 + m

Subtract 16 from both sides of the equation

19 - 16 = 16 - 16 + m

3 = m

(5) a + 15 = 11

Subtract 15 from both sides of the equation

a + 15 - 15 = 11 - 15

a = - 4

(6) p - 8 = - 8

Add 8 to both sides of the equation

p - 8 + 8 = - 8 + 8

p = 0

(7) - 17 + x = - 24

Add 17 to both sides of the equation

- 17 + 17 + x = - 24 + 17

x = - 7

(8) 4 + n = 13

Subtract 4 from both sides of the equation

4 - 4 + n = 13 - 4

n = 9

(9) - 3x = 0

Divide both sides of the equation by - 3

- 3x/-3 = 0/-3

x = 0

(10) 0.6 = m - 0.8

Add 0.8 to both sides of the equation

0.6 + 0.8 = m - 0.8 + 0.8

1.4 = m

(11) x - 5.3 = 1.27

Add 5.3 to both sides of the equation

x - 5.3 + 5.3 = 1.27 + 5.3

x = 6.57

A linear equation has a constant slope.

For every step increase in x, there needs to be another step increase in y.

From the table,

x decreases by 2 units

y doesn't decrease by the same unit
