Answer:

46

Step-by-step explanation:

turn the percentage into a fraction

so 20% is equal to 2/10.

230 is the whole number so multiply is by the numerator which is 2

230 x 2=460

and divide it by the denominator which is 10

460/10=46

Answer:

[tex]y=2x+5[/tex]

Step-by-step explanation:

[tex](5,0)[/tex]

Since the y-axis is cross on 5, that's the slope.

y=mx+5

To find x, let's use the formula;

[tex]m=\frac{rise}{run}[/tex]

[tex]m=\frac{6}{3}=2[/tex]

Answer:

6a

Step-by-step explanation:

The GCF (Greatest Common Factor) is a number/variable that you can take out of all of the terms in the expression.

In this case, each term in this expression has a 6, and an a, but not all have an x, so we only take out:

6a

By taking 6a, you get:

6a([tex]x^2[/tex] + x + 1)

Answer:

1/36

Step-by-step explanation:

If the cubes are numbered from 1 to 6 there is just one way that the sum of both of them equals 12 and this is when Marsha gets 6 in the first cube and 6 in the other.

Thus, to know what the probability that the total of numbers facing up will equal 12 we would have to calculate the probability that the first cube is 6 AND the second one is also 6.

The probability that the first cube has the number 6 is: 1/6

The probability that the second cube has the number 6 is: 1/6

We need to multiply this numbers because they both have to be 6 (rule of multiplication),

so: [tex]\frac{1}{6}(\frac{1}{6} )= \frac{1}{36}[/tex]

Thus, the probability that the sum of them equals 12 is 1/36

Answer:

n=42

Step-by-step explanation:

Hey there!

Let's think of both of these functions as two different slope-intercept equations (y=mx+b). Don't let all of the fs and gs confuse you; those are just showing that they are two different functions!

Our function f has an equation of y=x, which is a diagonal line that passes through the origin and goes across each small grid on the graph diagonally.

Our function g has an equation of y=-1/3x+2, which means that it will intersect with the y-axis at two units above the origin and for every three whole steps it goes to the right, it will have gradually gone down one whole step as well.

Attached to my answer is what a graph of it would kind of look like. Sorry if the lines don't look too much like a line it's a bit difficult to draw with a mouse haha!

I hope that this helps! Have a wonderful day!

Answer:

b = 2 x .  

(9+2x) (9-2x)

Step-by-step explanation:

Since both terms are perfect squares, factor using the difference of squares formula,  a 2 − b 2 = ( a + b ) ( a − b )

Answer:

Step-by-step explanation:

81 - 4[tex]x^{2}[/tex]

         notice how this is difference of squares, meaning you can simplify

(9-2x) (9+2x)

         if the question is asking to find roots, then you just set this equal to 0, and that means that either 9-2x or 9+2x must be equal to 0.

9-2x = 0                    9+2x = 0

9 = 2x                       9 = -2x

x = 4.5                      x = -4.5

Therefore the two roots of this equation are ±4.5

Answer:

-24

Step-by-step explanation:

To find the y intercept, plug x in as 0.

Answer:

-24

Step-by-step explanation:

Y intercept is where graph cuts the y axis and it satisfies x=0

So put x=0 in your equation

F(0)= -8 x 3

F(0)= -24

Therefore y-intercept= -24

Answer:

Its B. y-5x+5

Step-by-step explanation:

Use the slope formula

The equation of the linear model is y = 5x + 5. The correct answer is option B.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We can find the equation of the linear model passing through two points using the slope-intercept form of a line:

y = mx + b

where m is the slope of the line and b is the y-intercept.

First, we need to find the slope of the line:

m = (y₂ - y₁) / (x₂ - x₁)

Let (0, 5) be the first point, and (3, 20) be the second point:

m = (20 - 5) / (3 - 0) = 15 / 3 = 5

Now that we know the slope, we can plug in one of the points and solve for the y-intercept:

y = mx + b

5 = 5(0) + b

b = 5

Hence, the equation of the linear model is:

y = 5x + 5

Answer: [tex]17.33ft[/tex]

Step-by-step explanation:

We need to go from area to radius to circumference.

Formula for the area:

[tex]A=\pi r^2[/tex]

Solve for r;

Divide by pi

[tex]r^2=\frac{A}{\pi}[/tex]

Extract the square root.

[tex]r=\sqrt{\frac{A}{\pi} }[/tex]

Plug in the value of the area.

[tex]r=\sqrt{\frac{24ft^2}{3.14} } \\r=2.76ft[/tex]

Now that you've found the radius, use the circumference formula to calculate it.

[tex]C=2\pi r\\C=2(3.14)(2.76ft)\\C=17.33ft[/tex]

[tex](2x*4x)+(2x*-1)+(3*4x)+(3*-1)<8x^2+1[/tex]

[tex](8x^2)+(-2x)+(12x)+(-3)<8x^2+1[/tex]

[tex]8x^2-2x+12x-3<8x^2+1[/tex]

Subtract [tex]8x^2[/tex]

[tex]8x^2-2x+12x-3+(-8x^2)<8x^2+1+ (-8x^2)[/tex]

[tex]-2x+12x-3<1[/tex]

The cost price of the cycle is Rs.3240

Represent the cost price of the cycle with x and the selling price with y

A gain of 5% when the marked price is at a discount of 10% implies that:

[tex]5\%=\frac{(1 - 10\%)y-x}{x}[/tex]

Express 10% as decimal

[tex]5\%=\frac{(1 - 0.10)y-x}{x}[/tex]

[tex]5\%=\frac{0.90y-x}{x}[/tex]

Express 5% as decimal

[tex]0.05=\frac{0.90y-x}{x}[/tex]

Cross multiply

[tex]0.05x=0.90y-x[/tex]

Collect like terms

[tex]x + 0.05x=0.90y\\[/tex]

This gives

[tex]1.05x=0.90y[/tex]

Make y the subject of the formula

[tex]y = \frac{1.05x}{0.90}[/tex]

Also, when the discount is 5% and the profit is 351, we have:

[tex]351=(1 - 5\%)y -x[/tex]

Express 5% as decimal

[tex]351=(1 - 0.05)y -x[/tex]

This gives

[tex]351=0.95y -x[/tex]

Make y the subject

[tex]0.95y = 351 + x[/tex]

Substitute [tex]y = \frac{1.05x}{0.90}[/tex]

[tex]0.95 \times \frac{1.05x}{0.90} = 351 + x[/tex]

[tex]\frac{0.9975x}{0.90} = 351 + x[/tex]

Subtract x from both sides

[tex]\frac{0.9975x}{0.90} -x= 351[/tex]

Take LCM

[tex]\frac{0.9975x - 0.9x}{0.90}= 351[/tex]

[tex]\frac{0.0975x}{0.90}= 351[/tex]

Multiply both sides by 0.90

[tex]0.0975x= 315.9[/tex]

Divide both sides by 0.0975

[tex]x= 3240[/tex]

Hence, the cost price of the cycle is Rs.3240

Answer:

Step-by-step explanation:

Given a rhombus ABCD

|AB|=|DC| (Opposite sides of a rhombus are equal)

|AB|=9s+29

|DC|=10s-16

Therefore:

9s+29=10s-16

Collect like terms

10s-9s=29+16

Recall: |AB|=9s+29

|AB|=9(45)+29=405+29=434 Units

Since all the sides of a rhombus are congruent

AB=AC=BD=CD

Therefore:

|BC|=434 Units

Answer:

x = - 4.5, and x = 1

Step-by-step explanation:

~ Let us solve for x through factorization, but first change the equation to an expression for the simplicity ~

1. First break this expression into groups ⇒ ( 2x^2 - 2x ) + ( 9x - 9 )

2. Now factor 2x from 2x^2 - 2x ⇒ 2x ( x - 1 )

3. Now factor 9 from 9x - 9 ⇒ 9 ( x - 1 )

3. Combine these factored expressions ⇒ 2x ( x - 1 ) + 9 ( x - 1 )

4. Factor out common term x - 1 ⇒ ( 2x + 9 )( x - 1 )

5. Now add 0 to this expression as provided in the start: ( 2x + 9 )( x - 1 ) = 0

6. And now we recieve two answers, calculated through zero product property ⇒ 2x + 9 = 0   and   x - 1 = 0,  ⇒ 2x = - 9   and    x = 1   ⇒

x = - 4.5, and x = 1

The solution of the given expression would be as x = - 4.5, and x = 1.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

First we have to break this expression into groups

[tex]( 2x^2 - 2x ) + ( 9x - 9 )[/tex]

Now factor 2x

2x ( x - 1 )

Now factor 9 from 9x

9 ( x - 1 )

Combine these factored expressions as;

2x ( x - 1 ) + 9 ( x - 1 )

Then Factor out common term;

( 2x + 9 )( x - 1 )

Then add 0 to this expression as provided in the start;

( 2x + 9 )( x - 1 ) = 0

By zero product property

2x + 9 = 0   and   x - 1 = 0,  

⇒ 2x = - 9   and    x = 1  

x = - 4.5, and x = 1

The solution of the given expression would be as x = - 4.5, and x = 1.
