Answer:

To decrease it by 13% we will multiple (100-13 = 87) .

Step-by-step explanation:

Multiply the decimal form of the number (in this case 13) to the number.

For example: 13% of 50

13% can also be said as 0.13 in decimal form.

50*0.13=6.5

13% of 50 is 6.5.

The z-score of the person who scored 178 on the exam is fund as 2.8.

For the given question,

Mean μ = 150

Standard deviation σ = 10

Observed value x = 178.

The z-score is calculated as;

z = (x - μ)/σ

z = (178 - 150)/10

z = 28/10

z = 2.8

Thus, the z-score of the person who scored 178 on the exam is fund as 2.8.

The equation x/-2 = -9 has only one solution and is x = 18.

We are given an equation x/-2 = -9 for which we need to check whether it has a solution, no solution or infinite solutions.

For this we first solve this equation.

x/-2 = -9

Answer: 9/16 as a decimal is 0.5625

9-16-as-a-decimal-is-0.5625

Let's look into the two methods to write 9/16 as a decimal.

Explanation:

Method 1: Writing 9/16 as a decimal using the division method

To convert any fraction to decimal form, we just need to divide its numerator by denominator.

Here, the fraction is 9/16 which means we need to perform 9 ÷ 16

This gives the answer as 0.5625. So, 9/16 as a decimal is 0.5625

Method 2: Writing 9/16 as a decimal by converting the denominator to powers of 10

Step 1: Find a number such that we can multiply by the denominator of the fraction to make it 10 or 100 or 1000 and so on.

Step 2: Multiply both numerator and denominator by that number to convert it into it's an equivalent fraction.

Step 3: Then write down just the numerator, putting the decimal point in the correct place, that is, one space from the right-hand side for every zero in the denominator.

9/16 = (9 × 625) / (16 × 625) = 5625/10000 = 0.5625

Irrespective of the methods used, the answer to 9/16 as a decimal will always remain the same.

You can also verify your answer using Cuemath's Fraction to Decimal Calculator.

Thus, 9/16 as a decimal is 0.5625

If a value that is is greater than 100% of the original value will always be larger than original value.

If a value is less than 1% of the original value will always be less than the original value.

Given,

A value that is greater than 100% of the original value.

And it is 1% less than the original value.

We have to compare these values with the original value;

That is,

A value that is greater than 100% of the original value,

eg;

130% of 20 = 20 × 130/100 = 26

26 is greater than 20.

That is,

If a value that is is greater than 100% of the original value will always be larger than original value.

Next,

It is 1% less than the original value.

eg;

1% of 20 = 1/100 × 20 = 0.2

0.2 is less than 20

That is,

If a value is less than 1% of the original value will always be less than the original value.

A = students who passed the test = 14

B = students who completed the assignment = 13

N = Total students = 22

(A⁺ ∩ B⁺) = 6

P(A ∪ B) = 1 - 6/22 = 8/11

P(A ∩ B) = P(A) + P(B) - P(A ∪ B) = 14/22 + 13/22 - 8/11 = 1/2

P(A|B) = P(A ∩ B)/P(B) = (1/2)/(13/22) = 11/13 ≈ 0.85 ≈ 85%

The value of r is calculated as (m/-6) + 3 for the line with undefined slope passing through (3,2) and (r,-4).

We must determine the value of r that gives the line passing through (3,2) and (r,-4) an undefined slope.

Let,

x₁ = 3

y₁ = 2

x₂ =r

y₂ = -4

slope = m

Using the slope equation we get,

m = (y₂ - y₁)/(x₂ - x₁ )

m = (-4-2)/(r-3)

m/-6 = r - 3

r = (m/-6) + 3

Therefore, the value of r is calculated as (m/-6) + 3 for the line passing through (3,2) and (r,-4) with undefined slope.

The radius of the hole to the nearest hundredth of a foot is 2.88 feet.

What is radius?

The volume of the cylinder, V = 4200 cubic feet

Height, H = 2.1 miles = 11088 feet

The volume of the cylinder is given by the formula, V =πr²H

Putting values in the formula to find out radius,

4200=πr²(11088)

r²=[(11088)π]/4200

r²=8.2938

r=2.879~2.88 feet

Answer:

Step-by-step explanation:

We have a + 1/a = 5

(a + 1/a)² = a² + (1/a²) + 2.a.1/a =  a² + (1/a²)  + 2

But (a + 1/a)² = 5² = 25

So a² + (1/a²) = 25 - 2 = 23

(a + 1/a)³ = a³ + 3a²(1/a) + 3a(1/a)² + (1/a)2

= a³ + 1/a³ + 3a + 3/a

= a³ + 1/a³ + 3(a + 1/a)

= a³ + 1/a³ + 3(5)

=  a³ + 1/a³ + 15

But (a + 1/a)³ = 5³ = 125

So

a³ + 1/a³ + 15 = 125

a³ + 1/a³  = 110

Answer:

23 and 110

Step-by-step explanation:

using the expansion

(a + b)² = a² + 2ab + b² , then

a + [tex]\frac{1}{a}[/tex] = 5 ( square both sides )

(a + [tex]\frac{1}{a}[/tex] )² = 5²

a² + 2(a × [tex]\frac{1}{a}[/tex] ) + [tex]\frac{1}{a^2}[/tex] = 25

a² + 2(1) + [tex]\frac{1}{a^2}[/tex] = 25

a² + 2 + [tex]\frac{1}{a^2}[/tex] = 25 ( subtract 2 from both sides )

a² + [tex]\frac{1}{a^2}[/tex] = 23

---------------------------------------------------------------------

using the expansion

(a + b)³ = a³ + b³ + 3ab(a + b) , then

a + [tex]\frac{1}{a}[/tex] = 5 ( cube both sides )

(a + [tex]\frac{1}{a}[/tex] )³ = 5³

a³ + [tex]\frac{1}{a^3}[/tex] + 3(a × [tex]\frac{1}{a}[/tex] )(a + [tex]\frac{1}{a}[/tex] ) = 125

a³ + [tex]\frac{1}{a^3}[/tex] + 3(1)(5) = 125

a³ + [tex]\frac{1}{a^3}[/tex] + (3 × 5) = 125

a³ + [tex]\frac{1}{a^3}[/tex] + 15 = 125 ( subtract 15 from both sides )

a³ + [tex]\frac{1}{a^3}[/tex] = 110

Step-by-step explanation:

y2-y1 / x2-x1

-4 -(-3) / -5 - 4

Double negative switches the # to a positive

-4+3 / 5 - 4

= -1 / -9

Two negatives equal a positive

m=1/9

y-y1=m(x-x1)

y-(-3)=(1/9)(x-4)

Double negative=positive #

y+3=(1/9)(x-4)

Distribute (1/9) to the x and -4

y+3= (1/9)x - (4/9)

Subtract 3 from both sides

y = -3.4

Using substitution method, For the given equations, the value of x is 1/2 or x = -3

A fundamental operation in computer algebra is substitution. In computer algebra systems, it is frequently abbreviated as "subs" or "subst."

When a variable (or set of letters) in an algebraic statement is substituted, its numerical value is used instead. The expression's total value can then be calculated.

Given,

y= 9 - x

y= 2x² + 4x + 6

Substituting the value of y from 1 equation to other.

⇒ 9 - x = 2x² + 4x + 6

Now factorizing the equation,

⇒ 2x² + 5x - 3 = 0

⇒ 2x² + 6x - 1x - 3

⇒ 2x(x + 3) -1 (x + 3)

⇒ (2x - 1) (x + 3)

It will take 300 minutes to fill the pool if only 3 taps are used

From the question, we have the following parameters that can be used in our solution:

Number of taps = 5 taps

Number of minutes = 180 minutes

From the above parameter, we can calculate the constant of proportionality

The constant of proportionality is calculated as

Constant of proportionality = Number of taps * Number of minutes

Substitute the known values in the above equation

So, we have the following equation

Constant of proportionality = 5 * 180

Evaluate the quotient

Constant of proportionality = 900

The number of minutes it will take to fill the pool is then calculated as

Constant of proportionality = Number of taps * Number of minutes

Where

Constant of proportionality = 900

Number of taps = 3

Substitute the known values in the above equation

So, we have the following equation

900 = 3 * Number of minutes

This gives

Number of minutes = 900/3

Evaluate

Number of minutes = 300

Hence, the number of minutes is 300 minutes
