Which ratios form a proportion?
4/10 and 10/25
3/5 and 9/25
4/11 and 6/13
4/9 and 9/4​

Answer:

y=4x+3

I used the formula: y=mx+b

Explanation:

Think of 6 + y - 3 as 6 + 1y - 3

y and 1y are the same thing because 1 times any number is that same number.

The coefficient is the number to the left of the variable, so the coefficient is 1.

Answer:

$25

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

putting time into years for simplicity,

12 months ÷ 12 months/year = 1 years,

then, solving our equation

I = 500 × 0.05 × 1 = 25

I = $ 25.00

The simple interest accumulated

on a principal of $ 500.00

at a rate of 5% per year

for 1 years (12 months) is $ 25.00.

Given:

The table of values for Fallon's earnings in terms of Donald's earnings.

To find:

The equation that best represents Fallon's earnings in terms of Donald's earnings.

Solution:

In the given table the x-values are increasing by 5 units and  y values increasing by 5 units. It means the rate of change of y with respect to x is constant and the table represents a linear function.

If the graph of a linear function passes through two points, then the equation of linear function is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Consider any two points from the table. Let the two points are (38,45) and (43, 50). Then, the equation is

[tex]y-45=\dfrac{50-45}{43-38}(x-38)[/tex]

[tex]y-45=\dfrac{5}{5}(x-38)[/tex]

[tex]y-45=1(x-38)[/tex]

[tex]y-45=x-38[/tex]

Adding 45 on both sides, we get

[tex]y=x-38+45[/tex]

[tex]y=x+7[/tex]

Therefore, the correct option is A.

Answer:

slope is m= y_2-y_1/x_2-x_1 and the y-intercept is where the line crosses over the x-axis

Step-by-step explanation:

fill in the points and do the equation m= rise(y points)/ run(x points)

m=slope

(x_1, y_1) =coordinates of first point in the line

(x_2, y_2)=coordinates of second point in the line

Answer:

30%

Step-by-step explanation:

182-140=42(increase)

increase ÷ original × 100 %

= 42÷140×100%

=30%

The percentage increase from the old number to new number is 30 percent.

Given that, Max completed 140 questions on DFM last week. This week, Max completed 182 questions.

We know that, percentage increase = (New Number - Original Number)/Original Number ×100

= (182-140)/140 ×100

= 42/140 ×100

= 4200/140

= 30%

Therefore, the percentage increase is 30 percent.

Answer: 5.81%

Step-by-step explanation: Delta Math

A = 17700. P = 9900. t = 10

17700 = 9900e^r(10)

17700/9900 = 9900e^10r/9900

1.7878788 = e^10r

In(1.7878788) = In(e^10r)

In(1.7878788) = 10r

In(1.7878788)/10 = 10r/10

0.058103 = r

5.8103% = r

r = 5.81%

Answer:

Number of students in a student group = 8

Step-by-step explanation:

Let number of student in a student group = x

∴ Kevin lead 150 adults and 6x students

⇒Kevin lead = 150 + 6x

And,

Monica lead 134 adults and 8x students

⇒Monica lead = 134 + 8x

So, the number of students are equal

⇒150 + 6x = 134 + 8x

⇒150 - 134 = 8x - 6x

⇒16 = 2x

⇒x = [tex]\frac{16}{2}[/tex] = 8

∴ we get

Number of students in a student group = 8

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.

The shape congruent to given figure is Figure 4.

Option D is correct.

Congruent figures have sides that are the same length and angles that are the same measurement. In other terms, two figures are said to be congruent when they are superimposed upon one another. Even when they are flipped or rotated, they perfectly fit on top of one another.

We have a figure which is similar to parallelogram.

First, figure is seems to be rectangle and do not have same unit measurement which is not Congruent.

Now, the second has more width than given figure.

Now, Third figure is also a rectangle and cannot be congruent.

Now, the fourth figure is similar to given figure.

The original image undergoes reflection across x=-3.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

In the given graph DEFG is the original image.

D'E'F'G' is the new image after the transformations applied.

A reflection is defined by the axis of symmetry or mirror line. In the above diagram, the mirror line is x = -3.

Under reflection, the shape and size of an image is exactly the same as the original figure.

This type of transformation is called isometric transformation.

Hence, the original image undergoes reflection across x=-3.

Answer:

7/18

Step-by-step explanation:

Probability is the ratio of the number of possible outcomes to the number of total outcomes.

Given that there are 9 counters in a bag, 7 are green while 2 are blue.

the probability of picking at random a

Green counter = 7/9

Blue counter = 2/9

The probability that Ria takes one counter of each colour if 2 counter are picked as random is Green and Blue or Blue and Green

This is

=7/9 * 2/8 + 2/9 * 7/8

Recall that when a counter is picked the number of that ball available reduces and so does the total number of counter

=14/72 + 14/72

= 28/72

= 7/18
