Answer:

required answer. is 1/x³

Answer:

you find the x and y intersepts and draw the line

Step-by-step explanation:

if we break down the equasion in the end it's y=x+4 and from there we can find the intersepts by canceling out, y=x+4 becomes y=4 and 0=x+4 wich is x=-4

Answer:

hello :) the answer is 30 m/s

Answer:

30m/s

Step-by-step explanation:

Convert km to m:

108 —> 108000

Convert hr to s

1 —> 3600

Now put them back into their place in the fraction: 108000/3600

Simply the fraction: 30m/s

Answer:

15%

Step-by-step explanation:

GIven data

Initial population=  354,000

Final population=407,100

%Error= Final- Initial/initia*100

%Error= 407,100- 354,000/ 354,000*100

%Error= 53100/ 354,000*100

%Error=0.15*100

%Error=15%

Hence the error is 15%

Move 12 units to the right and 24 units up to complete the conversion from point A to point  A'

Answer:

[tex]\textsf{B.} \quad 3.14, \; \pi, \; \dfrac{22}{7}, \;\sqrt{10}[/tex]

Step-by-step explanation:

The given set of numbers (in any order) is:

[tex]\pi, \;\sqrt{10}, \; 3.14, \; \dfrac{22}{7}[/tex]

Convert each number to its decimal equivalent to 4 decimal places:

[tex]\implies \pi=3.1416\;(\sf 4\;d.p.)[/tex]

[tex]\implies \sqrt{10}=3.1623\;(\sf 4\;d.p.)[/tex]

[tex]\implies 3.14 = 3.1400\;(\sf 4\;d.p.)[/tex]

[tex]\implies \dfrac{22}{7}=3.1429\;(\sf 4\;d.p.)[/tex]

Each number has 3 units and 1 tenth.

Comparing the hundredths, all the numbers have 4 hundredths except √10 which has 6 hundredths.  Therefore, √10 is the largest number since 6 > 4.

Comparing the thousandths of the other three numbers, 3.14 is the smallest number as it has zero thousandths.

π is the next smallest as it has a one thousandth.

Therefore, the given set of numbers in increasing order is:

[tex]3.14, \; \pi, \; \dfrac{22}{7}, \;\sqrt{10}[/tex]

Answer:

720 grams of flour.

10.8 grams of salt.

14.4 grams of yeast

36 ml of oil.

Step-by-step explanation:

The recipe is:

600g flour

9g salt

12g yeast

30ml oil

500ml water

Now we use 600ml of water.

We can take the quotient between the amount of water we use and the amount of water in the recipe, this is:

600ml/500ml = 1.2

Then the ratio between the quantities we need to use and the quantities un the recipe should be always 1.2

Or the quantities that Eli needs to use will be 1.2 times the ones shown in the recipe.

Then she needs to use:

1.2*600g flour = 720 grams of flour.

1.2*9g salt = 10.8 grams of salt.

1.2*12g yeast = 14.4 grams of yeast

1.2*30ml oil = 36 ml of oil.

Answer:

4.

Step-by-step explanation:

There are 18 squares, if you want to shade 2/9 you have to make the denominator, which is 9 into 18, so you multiply by 2, you will do the same thing to the numerator, 2x2=4 9x2=18.

Brainiest would be appreciated.

There are 4 squares that would have to be shaded so that 2/9 of the shape is shaded.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

We have to determine the number of squares that would have to be shaded so that 2/9 of the shape is shaded

According to the given figure,

There are 3 rows and 6 columns of squares

So the number of squares would be 3 × 6 = 18

There are 18 squares, therefore if you want to shade 2/9, you must first divide the denominator, which is 9 into 18, by 2, and then multiply by 2.

If 2/9 of the shape is shaded: 18 × 2/9 ⇒ 36/9 = 4

Hence, there are 4 squares that would have to be shaded so that 2/9 of the shape is shaded.

Answer:

No.

Step-by-step explanation:

If she is riding 15 miles per hour (the rate), and she has six hours (the time), then in order to find out the distance, we multiply the rate*the time.

15*6 = 90

90<96

So, no, she will not make it.

Answer:

A ≈ 5.1 units²

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] × 2 sides × sin (angle between them ) , then

A = 0.5 × 7 × 3 × sin29° ≈ 5.1 units²

Answer:

The answer is option A. Since you would be paying 0.10 for each bag.

The solution is Option A.

The best deal for Maggie to buy the bag of potato chips would be 9 bags for $ 0.90 because each bag cost $ 0.10

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of each bag be represented as A

Now , the equation will be

a)

$0.90 for 9 bags of chips

The cost of 9 bags = $ 0.90

The cost of 1 bag A = The cost of 9 bags / 9

Substituting the values in the equation , we get

The cost of 1 bag A = 0.90 / 9

On simplifying the equation , we get

The cost of 1 bag A = $ 0.10

b)

$0.84 for 7 bags of chips

The cost of 7 bags = $ 0.84

The cost of 1 bag A = The cost of 7 bags / 7

Substituting the values in the equation , we get

The cost of 1 bag A = 0.84 / 7

On simplifying the equation , we get

The cost of 1 bag A = $ 0.12

c)

$1.50 for 5 bags of chips

The cost of 5 bags = $ 1.50

The cost of 1 bag A = The cost of 5 bags / 5

Substituting the values in the equation , we get

The cost of 1 bag A = 1.50 / 5

On simplifying the equation , we get

The cost of 1 bag A = $ 0.30

Therefore , the 0.10 < 0.12 < 0.30

Hence , the cost of $0.90 for 9 bags of chips is the best deal

Answer:

look at the explanation

Step-by-step explanation:

hey hey. i’ll help you. sorry if this is long. :)

okay so let’s think about this. there’s a lot of extra information that we don’t need so let’s get rid of everything up to ”7 years”.

now.. she works 40 hours per week right? and she makes $2.13 per hour. so now that we have that, let’s think what 40 x $2.13 is. if you do the math right you should get 85.2 or $85.20. so that’s in one week, but then in a typical week sheserves 75 tables that have an average bill of $4q. so now that we have those numbers, we take 41 x 75 then add it to our weekly number. so we multiply the two together and we get 3075. not 30.75 but $3075.00! so take that and add it to 85.20.. you should get 3160.2, or $3160.20. but then typically an 18% tip, so let’s go back to the number before (41) and find what 18% of 41 is.

18% of 41 is 7.38 or in this case, $7.38. so once we have that, you’re gonna want to multiply 7.38 by 75 to get that total. if you do that you should get 553.5

okay.. now we have all the numbers we need. we’re already basically done, we just need to add the tips to the other total!

$3160.20 + $553.50 = $3713.70

so in a week, she makes $3713.70

i hope this helped you! good luck!

Answer:

$45 after the discount

Step-by-step explanation:

Set up a proportion.

     [tex]\frac{x}{50} = \frac{10}{100}[/tex]      $50 is the total amount and make the 10% a decimal

x(100) = 50(10)

100 = 500

100 ÷ 500

x = 5     <-- We have to subtract this amount from the total

$50 - $5 = $45 <-- total after the discount

Hope this helps!!
