Answer:

0.78

Step-by-step explanation:

The constant of proportionality is the "k" in y = kx.

y is the dependent variable (whatever you do to x changes y)

x is the independent variable (it doesn't change in relation to y)

Your pounds of apples is your x

Your cost is your y

From the first row: 0.78 = (k)(1), which simplifies to k = 0.78

If you want to test it out, pick another line:

y = kx

3.12 = (k)(4)

divide both sides by 4

k = 0.78

It's great when tables like this have something in the x column that is a 1...because then the y is also the k

Answer:

12 by 12

Step-by-step explanation:

The area of a square is [tex]s^2[/tex], where [tex]s[/tex] is side length of the square. Therefore, we have:

[tex]s^2=144,\\s=\sqrt{144}=12[/tex]

Since all side lengths of a square are equal, the dimensions are 12 by 12.

Answer:

Step-by-step explanation:

area of square=l^2

144=l^2

[tex]\sqrt{144[/tex]=l

12=l

therefore the dimensions of square is 12 x 12.

Answer:

6

Step-by-step explanation:

60÷6 = 10

so we know the right side of the equal sign must equal 10

36÷6 = 6

now we know that (24÷n) must equal 10-6

we can write and equation like this:

24/n = 4

cross-multiply to get:

4n = 24

n = 24/4

n = 6

Answer:

60 ÷ 6 = ( 36 ÷ 6) + (24 ÷ ___)

10 = 6 + (24÷6)

10 = 6 + 4

10 = 10

Hello! answer: a = 8

Step-by-step explanation:

2.4 × 8 = 19.2

19.2 + 8 = 27.2 therefore a = 8 hope that helps!

Answer:

a = 8

Step-by-step explanation:

2.4a + 8 = 27.2

2.4a + 8 - 8 = 27.2 - 8

2.4a = 19.2

2.4a ÷ 2.4 = 19.2 ÷ 2.4

a = 8

Answer:

Solution given

Cos I=adjacent/hypotenuse=16/34

8/17 is a required answer.

The value of the trigonometric ratio of cosI is 8/17 if the length of the side adjacent to the angle is 16 units and the length of the hypotenuse is 34.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle and the trigonometric ratio are defined as the ratio of the pair of sides of a right-angled triangle.

We have a right-angled triangle in the picture.

If we take ∠I to calculate the ratio of cosec.

We know the cos is the ratio of the side adjacent to the angle to the side opposite to the right angle.

The length of the side adjacent to the angle A = 16 units

The length of the side opposite to the angle H = 34 units

Then

[tex]\rm cosI = \frac{A}{H}[/tex]

[tex]\rm cosI = \frac{16}{34}[/tex]

[tex]\rm cosI = \frac{8}{17}[/tex]

Thus, the value of the trigonometric ratio of cosI is 8/17 if the length of the side adjacent to the angle is 16 units and the length of the side opposite to the right angle is 34.

Answer: y = 8

Step-by-step explanation:

Answer:

39.2 is the mean

the deviation is 15.2

Step-by-step explanation:

the mean of a set of numbers is the sum divided by the number of terms = 39.2

the deviation measures the spread of a data distribution of the sample = 15.2

Answer:

10.8

Step-by-step explanation:

To find the mean absolute deviation, first you need to find the mean. To find the mean, add up 23 + 42 + 36 + 63 + 31 and you'll get 195. Divide 195 by the total of numbers, which is 5, and you'll get 39.

After finding the mean, you need to find the distance between the mean, which is 39, and the numbers given. 23 is 16, 42 is 3, 63 is 24, 31 is 8, and 36 is 3. Then, you'll need to calculate the mean of the distances that you got.

16 plus 3 plus 24 plus 8 plus 3 = 54. Once you got this, divide 54 by the total of numbers, which is 5, and you'll get 10.8.

Answer:

Step-by-step explanation:

Simon needs 1000 ML of milk

Craig needs 60 G of butter

Answer:

Craig needs 7.5g of butter to make 12 pancakes.

Step-by-step explanation:

To calculate how many times you need to multiply 8 by to make 12, simply divide 12 by 8. This gives you 1.5.

1.5*5 =7.5

So Craig needs 7.5g of butter to make 12 pancakes.

Step-by-step explanation:

plug in y

6=1/3x+11/15

multiply both sides by 15 to get rid of the fraction

90 = 5x +11

move terms to make them like terms

-5x =11- 90

-5x = -79

divide both sides by -5

evaluate for x

Answer:

4 weeks

Step-by-step explanation:

basic math

Answer:

6.5 weeks without parental help, 3.5 weeks with help from your parents.

Step-by-step explanation:

The Equation is:

Y = 20x

Y = Starting price for bikes

X = # of weeks

Therefore:

$130 = 20x

This can be simplified by solving for x

x = 130/20

x = 6.5 weeks

If your parents gave you $60 to help buy the bike the equation would be written as:

Y = 20x + 60

$130 = 20x + 60

Subtract 60 from both sides to get:

$70 = 20x

Solve for x

x = 70/20

x = 3.5 weeks

Answer:

27x-4

Step-by-step explanation:

Answer:

x = 12

y = 9

z = 11

Step-by-step explanation:

so, let's just do all the calculations in there :

(3×5)⁴ = 3⁴×5⁴

(2×3)⁵ = 2⁵×3⁵

(2×5)⁷ = 2⁷×5⁷

multiplying all 3 terms is then

3⁴×5⁴×2⁵×3⁵×2⁷×5⁷

more let's "group" and combine these terms based on the bases of the power operations, as we need to get an expression showing 2, 3 and 5 with their powers.

so, for the base of 2 we have

2⁵×2⁷ = 2¹²

for the base of 3 we have

3⁴×3⁵ = 3⁹

fire the base of 5 we have

5⁴×5⁷ = 5¹¹

so we get

2¹² × 3⁹ × 5¹¹

=>

x=12

y=9

z=11

Answer:

Hello! answer: y = 122

Step-by-step explanation:

360 - 116 = 244 244 ÷ 2 = 122 therefore y = 122

Hope that helps!

Answer:

x= z (vertically opposite angles)

x+z= 116

x+x = 116

2x= 116

x=116/2

x= 58

x+y= 180°(straight angle)

58°+y= 180°

y= 180°-58°

y = 122°

Answer:

800 in²

Step-by-step explanation:

Applying,

TSA (A) = Area of the base+ Lateral area of the

A = lw+1/2ps................ Equation 1

Where l = lenght of the base, w = width of the base, p = perimeter of the base, s = slight height of the base.

But,

p = 2(l+w)............. Equation 2

Substitute equation 2 into equation 1

A = lw+1/2[2(l+w)s)

A = lw+s(l+w)............. Equation 3

From the question,

Given: l = 16 in, w = 16 in, s = 17 in

Substitute these values into equation 3

A = (16×16)+17(16+16)

A = 256+544

A = 800 in²

Comparing with Equation of circle( x - h )²+ ( y - k )² = r²,

center of circle = (h,k) = (1,-3)

Radius of circle =√4 = 2unit

Answer:

[tex]\text{d) }p=0.35x+85[/tex]

Step-by-step explanation:

Since the 85 dollar fee is fixed, there should be no coefficient or constant that accompanies it. However, the total cost of the miles is directly proportional to the number of miles he drives. Thus, 0.35 should be accompanied by a constant that represents the total number of miles he drove. In this case, that constant is [tex]x[/tex] and [tex]0.35x[/tex] will represent the cost from the number of miles he drives in addition to the 85$ flat fee, hence [tex]\implies \boxed{\text{d) }p=0.35x+85}[/tex]
