Answer:

y=4x is the first answer

second answer id you will need 16 lemons

Step-by-step explanation:

The ratio is 3:12

if you divide 3 by 3 you will 1

and i you divide 12 by 3 you will get 4

keep in mind this is direct proportion whatever you do to one side you must do to the other

now that i have divided the ratio you get 1:4

meaning 1 pitcher for every 4 lemons that the relationship between x and y

y=4x

and if you make 4 pitchers you will need 16 lemons

hope this helped xx

Answer:

Input Variable: Number of chores

Output Variable: Earnings

Step-by-step explanation:

Given

Earnings = $3 per chore

Required

Determine the input and the output variables

The given parameter

Earnings = $3 per chore

i.e.

If he does 1 chore, he earns $3

If he does 2 chores, he earns $6

If he does 3 chores, he earns $9

---

--

-

If he does n number of chores, he earns $3n

So, we can conclude that:

His earning is dependent on the number of chores.

The keyword dependent shows that:

Input Variable: Number of chores

Output Variable: Earnings

$66.50.

Step-by-step explanation:

Answer:

Step-by-step explanation:

(10^2-6^2) gives the hypotenuse of the smaller triangle therefore we get 8 units for that side.looking for the value of x

(8^2-3^2)=x^2

(64-9)=x^2

55=x^2

X=√55

Answer:

Store C

Step-by-step explanation:

store a is selling 10 pencils for $2.50

$2.50 divided by 10 is 25 cents

so the price for store a is 25 cents per pencil

store b is selling 50 pencils for $6.00

$6.00 divided by 50 is 12 cents

so the price for store b is 12 cents per pencil

store c is selling 100 pencils for $8.25

$8.25 divided by 100 is 8.25 cents

obviously you can't give someone .25 cents so round it down to 8

so the price for store c is 8 cents per pencil

store d is selling 250 pencils for $21.25

$21.25 divided by 250 is 8.5 cents

which rounds up to 9 cents per pencil

Store c has the lowest price for one pencil

Answer:

60 cm^3

Step-by-step explanation:

The computation of the volume of the cuboid is given below:

let us assume the length be l

and b the breadth

So

l = b + 1

And, the perimeter is

2(l + b) = 18

2l + 2b = 18

2b + 2 + 2b = 18

b = 4

And l = 5

Now

2(l + b) × h = 54

2(5 + 4 ) × h = 54

h = 3

Now the volume of the cuboid is

= l × b × h

= 5 × 4 × 3

= 60 cm^3

197

Step-by-step explanation:

13.33% of 197 = 26.26

.26 < 0.5

So, 197 + 26 = 223

Answer:

x=196.77 ir 197

Step-by-step explanation:

197

Step by step explanation:

13.33% of 197 = 26.26

0.26 <0.5

So it can be ignored

So, 197 + 26 = 223

Answer:

x = 6

Step-by-step explanation:

8 - 2 = 6

7(8 - 2) = 7(6)

7x6 = 42, so

x = 6 is the correct answer

Since  6.38 is precise to the hundredth digit, so the answer must also be rounded/approximated to the nearest hundredth.

For the expression to be precise it has to have the approximation of the least number.

Therefore,

0.5 is 1 decimal place(nearest tenth)

6.38 is 2 decimal place(nearest hundredth)

Therefore,

The answer of the expression 0.5 +6.38  should be in hundredth digit.

Hence,

0.5 +6.38  = 6.88

The statement that 6.38 is precise to the hundredth digit, so the answer must also be rounded to the nearest hundredth is FALSE

When taking the sum of decimal numbers, the equivalent result must be rounded up to the decimal with least number of decimal place.

Given the expression

0.5 +6.38 = 6.88

The given result is wrong since it is not in 1 decimal place. The correct result should be 6.9. Hence the statement that 6.38 is precise to the hundredth digit, so the answer must also be rounded to the nearest hundredth is FALSE

Answer:

1. 12r= 2

2. 60r - 4= 6

3. 3r power of 2= 1/12

Step-by-step explanation:

1. 12r = 12* 1/6= 12/6= 2

2. 60r - 4 = 60* (1/6) -4= 60/6 -4= 10- 4=6

3. 3r power of 2= 3* (1/6) power of 2= 3* 1/36= 1/12

Answer:

m<ABC = 116°

m<CDE = 67°

Step-by-step explanation:

✔️m<ABC = 180 - m<BAD (adjacent angles of a parallelogram are supplementary)

m<ABC = 180 - 64° (Substitution)

m<ABC = 116°

✔️m<CDA = m<CDE + m<ADE (angle addition postulate)

m<CDA = m<CDE + 49°

m<CDA = m<ABC (opposite angles of a parallelogram are congruent)

m<CDE + 49° = 116° (substitution)

m<CDE = 116° - 49° (Substraction property of equality)

m<CDE = 67°

Answer:

Answer vary: to make 3 cakes this is what Matteo needs

9 ounces of butter

12 ounces of sugar

15 ounces of flour

6 eggs

3 teaspoons (tsp) baking powder

Step-by-step explanation:

honestly in my opinion thats my answer but it might be wrong. you could add or multiply it, I added the ingredients 3 times but it’s more simple to multiply each by 3.

3 times 3 = 9

4 times 3 = 12

5 times 3 = 15

2 times 3 = 6

1 times 3 = 3

Answer:

The answer is below

Step-by-step explanation:

1) The length of the south side of the field = (5x + 2) + (x² - 9) + (x² - 7x +12) = x² + x² + 5x - 7x + 2 - 9 + 12 = 2x² - 2x + 5

2) The perimeter of pumpkin field = 2(length + breadth) = 2[(5x - 2) + (5x + 2)] = 2[5x + 5x - 2 + 2] = 2(10x)

The perimeter of pumpkin field = 20x

3) The perimeter of pumpkin field is useful in case Bob wants to fence the pumpkin field.

4) The perimeter of potato field = 2(length + breadth) = 2[(x + 6) + (x² - 7x + 12)] = 2[x² - 7x + x + 6 + 12] = 2(x² - 6x + 18)

The perimeter of potato field = 2x² - 12x + 36

5) Area of squash field = length * breadth = (4x) * (x)

Area of squash field = 4x²

6) The area of the squash field would be important if Bob want to determine the number of squash seeds that would be enough for the field.

7) Area of pumpkin field = length * breadth = (5x - 2) * (5x + 2) = 25x² + 10x - 10x - 4

Area of pumpkin field = 25x² - 4

Area of pumpkin field and squash field = 4x² + (25x² - 4) = 29x² - 4
