y=8cm

Answer:

20 guests

Step-by-step explanation:

20 (20) + 400 = 400 + 400 = 800

10 (20) + 600 = 200 + 600 = 800

answer B = 20 guests

Answer:

For 20 persons the price would be same.

Step-by-step explanation:

y=y

20x+400=10x+600

20x-10x=600-400

10x=200

x=20

Therefore, for 20 persons the price would be same.

Answer:

24 kg

Step-by-step explanation:

21 kg every 7 hr

21kg/7hr = 3kg/hr

This means he prepares 3 kg of dough every hour.

After working 8 hours, he would have prepared (3kg)(8) = 24kg of dough

(7 hot dogs)/(4 minutes) = (23 hot dogs)/(x minutes)

7/4 = 23/x

7x = 4*23 .... cross multiplication

7x = 92

x = 92/7

x = 13.142857 approximately

x = 13.1

Answer:

x=0.2

Step-by-step explanation:

1 / 5 = 0.2

therefore

5 x 0.2 = 1

Since the value of y varies directly with x, the value of x when y equals 9 is [tex]\frac{9}{13}[/tex]

Given the following data:

To find the value of x when y = 9:

This is a direction proportion exercise and you're required to solve for the value of x when the value of y is equal to 9.

First of all, we would determine the constant of proportionality (k) for the mathematical expression.

[tex]y = kx\\\\15 = 195k\\\\k = \frac{195}{15}[/tex]

k = 13

Now, we can find x:

[tex]y = kx\\\\9 = 13x\\\\x = \frac{9}{13}[/tex]

Therefore, the value of x when y equals 9 is [tex]\frac{9}{13}[/tex]

Answer:

y = -1/6x + 2

Step-by-step explanation:

Slope: (-6,3) and (6,1) = (1-3) / (6 - - 6)

= - 2/12 = -1/6

b = 3 - (-1/6)(-6)

b = 3 - 1

b = 2

Answer:0

Step-by-step explanation:

The sum of a convergent geometric series can be calculated with the formula a ⁄ 1 – r, where “a” is the first term in the series and “r” is the number getting raised to a power. A geometric series converges if the r-value (i.e. the number getting raised to a power) is between -1 and 1. So the answer is 0

The complete similarity transformation is: triangle abc was dilated by a scale factor of [2], reflected across the [x-axis], and moved through the translation [0].​

From the figure, we have:

AB = 2 units

DE = 4 units

So, the scale factor (k) is:

k = DE/AB

k = 4/2

k = 2

So, the scale factor is 2

Also, both shapes are on either sides of the x-axis, and they are equidistant from the x-axis.

This means that the triangle is reflected across the x-axis with no translation.

Hence, the complete similarity transformation is:

abc was dilated by a scale factor of [2], reflected across the [x-axis], and moved through the translation [0].​

Answer:

k=3.5, and y=3.5x is the equation of the line

Step-by-step explanation:

y and x are proportional means that y = kx for some constant k.

Thus, when y=7 and x=2, we have that 7 = k * 2, so that k = 7/2 = 3.5,

and the equation of the line is y = 3.5x

Answer:

The unit rate is C. 50mph

Step-by-step explanation:

Take two points from the line,

I took points (1, 50) and (2, 100).

Then plug them into this formula:

y2-y1/x2-x1

Solve:

(100- 50)/(2 - 1)

100 - 50 = 50

2 - 1 = 1

50/1 = 50

So, you get C. 50mph
