Help plssss plsss???????

Answer: $213

Step-by-step explanation:

First find out how much is spent on the other things:

Utilities

= 15% * 420

= $63

Internet services

= 1/5 * 420

= $84

Phone service

= 1/7 * 420

= $60

The amount left for food is therefore:

= 420 - money spent on other things

= 420 - 63 - 84 - 60

= $213

Answer:

answer is 113.04 [tex]cm^{2}[/tex]

Step-by-step explanation:

Answer:

2n³ - 3n² - 7n + 3

Step-by-step explanation:

Given

(n² - 3n + 1)(2n + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

n²(2n + 3) - 3n(2n + 3) + 1(2n + 3) ← distribute the parenthesis

= 2n³ + 3n² - 6n² - 9n + 2n + 3 ← collect like terms

= 2n³ - 3n² - 7n + 3

Answer:

Ciera is driving at a faster rate.

Step-by-step explanation:

You calculate speed, by dividing distance by time.

So 18 divided by 24 is 0.75. That is Ciera's speed.

And then to calculate the other person/thing's speed you have to divide 46 by 60 minutes (equal to one hour). The speed calculates to 0.7666666667

Therefore, Ciera is driving faster.

Answer:

4%

Step-by-step explanation:

The percentage of the people polled like playing golf =( people that liked playing golf / total number of people polled) x 100

(4/100) x100 = 4%

She needs to convert all the numbers be be the same type ( fraction or decimal).

With the numbers she has it would be easiest to convert all the numbers to decimals.

72/80 = 0.9

3 1/5 = 3.3

Pi = 3.14

Now she can arrange the decimals in order:

-2.9, 0.9, 2.979, 3.14, 3.2

She needs to switch 3 1/5 and pi

Answer:

3 1/5 is tha one

Answer:

1 mile = 0.5 cm

Step-by-step explanation:

I hope this helps!

Hey again!

The answer to your question is 2 cm = 1 mile

We can solve this by doing 9/4.5, and we get 2. This means that every 2 centimeters in the scale drawing is equal to 1 mile in the actual.

Hope this helps!

Hey there!

Here is a graph of the points:

A scatterplot is a graph, but the points won't be able to connect in a straight line, and they have no relation.

A line of best fit is a line that goes evenly through the points, or as best as it could.

Answer:

The domain is all real number:

i.e.

[tex]-\infty \:<x<\infty \:[/tex]

Therefore,

[tex]\mathrm{Domain\:of\:}\:10^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Step-by-step explanation:

Given the function

y = 10ˣ

Determining the domain of the function y = 10ˣ :

We know that the domain of the function is the set of input or arguments for which the function is real and defined.  

In other words,

From the graph, it is clear that the function has no undefine points nor domain constraints.

Thus, the domain is all real number:

i.e.

[tex]-\infty \:<x<\infty \:[/tex]

Therefore,

[tex]\mathrm{Domain\:of\:}\:10^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Answer:

The domain is all real numbers

Step-by-step explanation:

Answer:

We conclude that:

[tex]\frac{x+2}{x+4}-\frac{x-1}{x+6}=\frac{5x+16}{\left(x+4\right)\left(x+6\right)}[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{x+2}{x+4}-\frac{x-1}{x+6}[/tex]

Least Common Multiple of x+4, x+6:  (x+4) (x+6)

Adjusting fractions based on the LCM

[tex]=\frac{\left(x+2\right)\left(x+6\right)}{\left(x+4\right)\left(x+6\right)}-\frac{\left(x-1\right)\left(x+4\right)}{\left(x+6\right)\left(x+4\right)}[/tex]

since the denominators are equal, combine the fractions:

[tex]\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]

so the expression becomes

[tex]=\frac{\left(x+2\right)\left(x+6\right)-\left(x-1\right)\left(x+4\right)}{\left(x+4\right)\left(x+6\right)}[/tex]

[tex]=\frac{x^2+8x+12-\left(x-1\right)\left(x+4\right)}{\left(x+4\right)\left(x+6\right)}[/tex]

[tex]=\frac{x^2+8x+12-x^2-3x+4}{\left(x+4\right)\left(x+6\right)}[/tex]

simplify

[tex]=\frac{5x+16}{\left(x+4\right)\left(x+6\right)}[/tex]

Therefore, we conclude that:

[tex]\frac{x+2}{x+4}-\frac{x-1}{x+6}=\frac{5x+16}{\left(x+4\right)\left(x+6\right)}[/tex]

Answer: AB=20, BC=14

Step-by-step explanation:

set AB together with the side congruent to it (which is DC)

3x-7=x+11

subtract x and add 7 to both sides

2x=18

divide both sides by 2

x=9

plug 9 in for AB.

3(9)-7

27-7=20.

now do the same for BC

Answer:

AB = 20

BC = 14

Step-by-step explanation:

ABCD is a parallelogram

Opposite sides of a parallelogram are equal.

Therefore,

AB = DC

3x - 7 = x + 11

3x - x = 11 + 7

2x = 18

x = 18/2

x = 9

AB = 3x - 7 =3*9 - 7 = 27 - 7 = 20

7y - 7 = 3y + 5

7y - 3y = 7 + 5

4y = 12

y = 12/4

y = 3

BC = 7y - 7 = 7*3 - 7= 21 - 7 = 14

Answer:

€120

Step-by-step explanation:

Let us represent

Ann = x

Brian = y

Carol = z

€400 is divided between Ann, Brian and Carol

Hence: x + y + z = €400...... Equation 1

Ann has twice as much as Brian

Hence:

x = 2y

Brian has three times as much as Carol.

y = 3z

z = y/3

We substitute

x + y + z = €400...... Equation 1

2y + y + y/3= €400

Multiply both sides by 3

2y × 3 + y × 3 + y/3 × 3 = €400 × 3

6y + 3y + y = €1200

10y = €1200

y = €1200/10

y = €120

How much does Brian receives ?

Since, Brian = y

Brian receives €120

Answer:

(-7,-3)

Step-by-step explanation:

You keep the -3 since that is the y but the x will become negative because you are reflecting to the left and not the right, making the x then negative.

Answer: (-7,-3)

Step-by-step explanation:

The point (7,-3) is located in the fourth quadrant  mean that if you reflect the point across the  y a-xis, it should end up in the third quadrant.

If you flip a point over the y axis, the x coordinate switches.

(7,-3) ⇒ (-7,-3)

Answer:

sum of interior angles of octagon is 1080 degrees

From figure ,

136 + 132 + 129 + 116 + 158 + 141 + 124 + x = 1080

so, x = 1080 - 936

        = 144

Step-by-step explanation: Simply add the angles and substract the sum from 1080 which is the sum of interior angles of octagon

Answer:

144 degrees.

Step-by-step explanation:

There are 8 sides to this polygon so the total internal of

angles = 180( 8 - 2)

= 1080

Adding up the 7 given angle we get  936

So x = 1080 - 936

= 144.

Answer: Add the two equations together to eliminate y

Step-by-step explanation:

X+y=3

I would use elimination since one equation has +y and one equation has -y

Add the two equations together

X+y=3

4x-y=7

Answer:

8 Three Points

Answer:

40

Step-by-step explanation:

To solve this question you will need to use BEDMAS which is the order of which numbers you have to solve first. In this case you need to solve the brackets first, then the exponent, and then lastly the addition.

 3^3 + 3(4 + 1/3)

= 3^3 + 3(13/3)

= 27 + 3 x 13/3

= 27 + 13

= 40

Answer:

x = 1/4

Step-by-step explanation:

[tex]log_{x}[/tex] 16 = 2 can be written as [tex]16^{x}[/tex] = 2

([tex]2^{4}[/tex])^x = 2^1

if bases are the same we can create this equation:  4x = 1

                                                                                      x = 1/4
