Step-by-step explanation:

24÷16=1.5

21÷1.5=14

Answer:

A=$2100

B=$1400

Step-by-step explanation:

3500*1.06=3710

a+b=3500

1.05a+1.075b=3710

1.05a+1.05b=3675

1.05a+1.075b=3710

Subtract 1.05a+1.05b=3675 from 1.05a+1.075b=3710

0.025b=35

b=1400

a=3500-1400=2100

Double check: (2100*1.05)+(1400*1.075)=3710

3500*1.06=3710

The amount invested in the account that pays a 5% interest is $2100 and the amount invested in the account that pays a 7.5% interest is $1400.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

0.05a + 0.075b = (0.06 x $3500)

0.05a + 0.075b = $210 ----- equation 1

a + b = $3,500   -------- equation 2

Where:

a is the amount invested in the account that paid a 5% interest.

b is the amount invested in the account that paid a 7.5% interest.

The amount invested in the account that pays a 7.5% interest.

In order to determine this value, multiply equation 2 by 0.05

0.05a + 0.05b = 175  ------- equation 3

0.025b = 35

b = $1400

The amount invested in the account that pays a 5% interest.

a + $1400 = $3500

a = $3500 - 1400

a = $2100

Therefore, The amount invested in the account that pays a 5% interest is $2100 and the amount invested in the account that pays a 7.5% interest is $1400.

Answer:

60

Step-by-step explanation:

Given that :

Total crop on corn plot = 1500

Total on soya bean plot = 3000

Total on grass plot = 500

Total plants = 5000

A Stratified sample of 200 corn plants is to be selected ;

Number of samples he takes from each plot:

Percentage of number of samples :

x% of 5000 = 200

0.01x * 5000 = 200

50x = 200

x = 200/50

x = 4%

Hence, number of plants to be selected from corn plot :

4% of 1500

0.04 * 1500

= 60

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left.

3) O(x,y)=(x-3,y+5)

The rule that describes the translation is (x, y) -> (x - 3, y + 5), the correct option is C.

The transformation of a function may involve any change.

Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units:

y=f(x+c) (same output, but c units earlier)

Right shift by c units:

y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y =[tex]k \times f(x)[/tex]

Horizontal stretch by a factor k: y = [tex]f\left(\dfrac{x}{k}\right)[/tex]

We are given that;

5 units up and 3 units to the left

Now,

In this case, the rectangle is translated 5 units up and 3 units to the left. This means that the vertical shift is 5 and the horizontal shift is -3.

After transformation x=x - 3

Y=y + 5

Therefore, the transforming function will be (x, y) -> (x - 3, y + 5).

Answer:

x = 2  +  √-16 [ (-2)⁻¹]

See steps below.

Step-by-step explanation:

Finding the zeroes of a function simply means solving for the unknown variable (in this case "x") when the function is equated to zero.

The function here is   [tex]f(x) = -(x + 1)^{2} - 4 = 0[/tex]

Start by opening the bracket. Ignore the minus sign. It will be reintroduced at the end of this step.

(x + 1)(x + 1)   = x² + x + x + 1    = x² + 2x + 1

Reintroduce the minus sign. Don't forget to put the result above back in a bracket.

- (x² + 2x + 1)  = -x² -2x -1

Place the expression back in the equation and solve. Make sure to put it back in the position where it was.

-x² - 2x - 1 - 4 = 0

Simplify the non-algebraic terms.

-x² - 2x - 5 = 0

Use Quadratic Formula to solve for x.

Quadratic formula: x =  -b ± √(b² - 4ac)

                                              2a

a = the coefficient of x² = -1

b = the coefficient of x  = -2

c = the unit term            = -5

So   x = -(-2)  ± √ [(-2)² - 4(-1 x -5)]

                       2(-1)

x = 2 + √-16                    or x = 2 - √-16

         -2                                          -2

This is where the evaluation ends, since the square root of minus sixteen cannot be evaluated. x hence is equal to a complex number. The above are the two values for x.

Next step is to put it in "a + bi" form.

x = 2  +  √-16  ÷  -2     =  2  +  √-16  x (-2)⁻¹

So   x = 2  +  √-16 [ (-2)⁻¹]

where

a is 2;

b is √-16

i is [(-2)⁻¹]

Answer:

you have a 1/5 chance of choosing a red marble.

Step-by-step explanation:

Answer:

Your probability of choosing  a red marble is 30%

Step-by-step explanation:

You'll need to start by adding all the marble's which will give you 100.

30 + 50 + 20 = 100

Then add up the non-red marbles, which is 70.

50 + 20 = 70

30 red marbles are left.

Now, you'll have the fraction 30 over 100.

As a percentage that would be 30%

Answer:

Please check the explanation.

Step-by-step explanation:

Given the system of equations

2 + 2y = 6

2x - 3y = 26

Let us solve the system of equations

[tex]\begin{bmatrix}2+2y=6\\ 2x-3y=26\end{bmatrix}[/tex]

Rearrange equations

[tex]\begin{bmatrix}-3y+2x=26\\ 2y=4\end{bmatrix}[/tex]

Multiply -3y+2x=26 by 2:    -6y+4x=52

Multiply 2y = 4 by 3:  6y = 12

[tex]\begin{bmatrix}-6y+4x=52\\ 6y=12\end{bmatrix}[/tex]

adding the equations

[tex]6y=12[/tex]

[tex]+[/tex]

[tex]\underline{-6y+4x=52}[/tex]

[tex]4x=64[/tex]

Solve 4x = 64 for x

[tex]4x = 64[/tex]

divide both sides by 4

[tex]\frac{4x}{4}=\frac{64}{4}[/tex]

Simplify

[tex]x = 16[/tex]

For -6y+4x = 52 plug in x = 16

[tex]-6y+4\cdot \:16=52[/tex]

Multiply the numbers: 4 · 16 = 64

[tex]-6y+64=52[/tex]

Subtract 64 from both sides

[tex]-6y+64-64=52-64[/tex]

Simplify

[tex]-6y=-12[/tex]

Divide both sides by -6

[tex]\frac{-6y}{-6}=\frac{-12}{-6}[/tex]

[tex]y=2[/tex]

Therefore, the solution to the system of equations be:

[tex]y=2,\:x=16[/tex]

Thus,

(x, y) = (16, 2)

Answer:

837.23 cm³

Step-by-step explanation:

La fórmula para el volumen de un prisma pentagonal se da como:

1/2 (5 s × a) × h

Dónde:

s = longitud lateral

a = Apotema

h = altura

De la pregunta anterior:

s = largo de lado = 6.1 cm

a = Apotema = 4.5 cm

h = Altura = 12.5 cm

Por lo tanto:

El volumen del prisma pentagonal =

1/2 (5 × 6.1 × 4.5) × 12.5

= 1/2 × 137.25 × 12.5

= 837.225 cm³

Aproximadamente = 837.23 cm³

This expression will simplify back to x-3y+7

Answer:

y= 1/3x-7/3

Step-by-step explanation:

We have: x-3y+7

There are many equivalent expressions we can create, but let's write this equation in slope- intercept form.

First step is to rearrange the terms: -3y=-x+7

But we are not done yet; now we divide both sides with -3: y=1/3x-7/3

(The negatives cancel out, which is why we get a positive 1/3)

Answer:

Determine if each relation is a relation or not

A function is represented as: [tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3)...(x_n,y_n)\}[/tex]

Where

[tex]x = domain[/tex] and [tex]y = range[/tex]

For a relation to be a function:

No x value (in other words, the domain) must be repeated

[tex](a):\ y = \frac{x + 3}{7}[/tex]

The above relation is a function. This is so because every unique value of x have a unique value of y.

In other words:

No two domains exist for a range

Conclusively, it is a one-to-one function

[tex](b):[/tex]

[tex]\begin{array}{ccccc}x & {-2} & {-2} & {1} & {3} \ \\ y & {-5} & {-1} & {3} & {7} \ \ \end{array}[/tex]

In the above table, we have:

[tex](x_1,y_1) = (-2,5)[/tex] and [tex](x_2,y_2) = (-2,-1)[/tex]

The domain (-2) points to range (5 and -1).

Based on the condition that no two domain should point to the same range, we can conclude that this is not a function.

[tex](c):[/tex]

[tex]\begin{array}{ccccc}x & {-3} & {-1} & {1} & {3} \ \\ y & {-4} & {-4} & {2} & {2} \ \ \end{array}[/tex]

In the above table, we have the domain to be:

[tex]x = \{-3,-1,1,3\}[/tex]

We can see that no x value is repeated.

Hence, this is a function.
