Answer:

C

Step-by-step explanation:

Darby's equation in slope-intercept form: y = 4x + 6

Where,

Slope (m) = 4

y-intercept (b) = 6

Let's find the slope (m) and y-intercept (b) of the line Samuel graphed using the values of the given table.

Slope (m) using (0, 6) and (2, 14)

Slope (m) = ∆y/∆x = (14 - 6)/(2 - 0) = 8/2

Slope (m) = 4

y-intercept (b) = 6, because at x = 0, y = 6. This is where the line intercepts the y-axis.

Now, we can see that both functions has the same slope (m) = 4, and the same y-intercept (b) = 6

Both will have the same line.

Answer:

Y = 6X-5

Step-by-step explanation:

substitute the value of slope and Y intercept in the standard equation Y = MX + B

where M is the slope and b is the y-intercept

Answer:

Step-by-step explanation:

Alright so we are going to solve

5x ≥ 25  Divide both sides by 5

x≥5

Answer:

Step-by-step explanation:

because both angles are vertical they are equal to each other

lets solve 3x+50=6x-10

add 10 to 60

3x+60=6x

subtract 3x from 6x

60=3x

divide 3 on both sides

20=x

X=20

I hope this helped :)

Answer: D) Qualitative data is not collected by instruments, it is just observations

Quantitative data deals with numeric values, which is collected by instruments usually. For example, if you're weighing various rocks, then each numeric weight value is part of the quantitative data set. The color of each rock would be qualitative data as you simply look at the rocks and record the color. It will depend on what question you're trying to answer as to whether quantitative data or qualitative data is more useful. Sometimes you may need both types.

Answer:

$210

Step-by-step explanation:

the expression is 25a+10c-5

where a=adults,c=children

and we have 5adults and 9 children

then 25a + 10c - 5 is

25(5)+10(9)-5

=125+90-5

=210

answer:Monica is going to purchase tickets for 5adults and 9 children for$210

Answer:

a) 910

b) 828100

c) 144320

Step-by-step explanation:

a. ∑y

This is the sum of all values of y. So

[tex]\sum y = 216 + 184 + 35 + 92 + 142 + 175 + 9 + 57 = 910[/tex]

b. (∑y)^2

This is the square of the sum, so the square of 910, that we found in the previous item.

910² = 828100

c. ∑y^2

This is the sum of the squares of each amount spent. So

[tex]\sum y^2 = 216^2 + 184^2 + 35^2 + 92^2 + 142^2 + 175^2 + 9^2 + 57^2 = 144320[/tex]

Answer:

Results are below.

Step-by-step explanation:

1. First, we need to calculate the Future Value:

FV= {A*[(1+i)^n-1]}/i

A= quarterly deposit

n= 10*4= 40

i= 0.12/4= 0.03

FV= {4,000*[(1.03^40) - 1]} / 0.03

FV= $301,605.04

Now, the present value:

PV= FV/(1+i)^N

PV= 301,605.04/(1.03^40)

PV= $92,459.09

2. First, we need to calculate the value of the first year of college:

FV= PV*(1+i)^n

FV= 24,000*(1.04^3)

FV= $26,996.74

Now, the quarterly payments:

FV= {A*[(1+i)^n-1]}/i

A= quarterly deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

i= 0.08/4= 0.02

n= 3*4= 12

A= (26,996.74*0.02) / [(1.02^12) - 1]

A= $2,012.87

Answer:

85 1/2 inches

Step-by-step explanation:

14 1/4 x 6 = 85 1/2 inches

Answer:

For s students, at least 6s liters of water will be needed. So, for 30 students, at least 6*30 = 180 liters of water will be needed.

Step-by-step explanation:

This question is solved by proportions, using rule of three.

I am going to say that:

s is the number of students.

l is the number of liters of water needed for s students.

I have found that with five students in the class at least 30 litres of water is needed.

This means that:

[tex]\frac{s}{l} = \frac{5}{30}[/tex]

[tex]5l = 30s[/tex]

[tex]l = \frac{30s}{5}[/tex]

[tex]l = 6s[/tex]

This means that for s students, at least 6s liters of water will be needed. So, for 30 students, at least 6*30 = 180 liters of water will be needed.

Answer:

35/3 or 11 2/3

Step-by-step explanation:

This is a division problem.

We need to divide 7 by 3/5.

7 / 3/5 = 7/1 / 3/5 = 7/1 * 5/3 = 35/3 = 11 2/3

Answer: 35/3 or 11 2/3

Answer:

Height, h = 20.99 millimeters.

Step-by-step explanation:

Given the following data;

Volume = 8792mm³

Radius = 20 mm

To find the height;

We know that the shape of an anthill is conical in nature.

Mathematically, the volume of a cone is given by the formula;

[tex] V = \frac{1}{3} \pi r^{2}h[/tex]

Where;

Substituting into the equation, we have;

[tex] 8792 = \frac{1}{3} * 3.142*20^{2}*h [/tex]

[tex] 8792 = \frac{1}{3} * 3.142*400*h [/tex]

[tex] 8792 = \frac{1}{3} * 1256.8*h [/tex]

[tex] 8792 = 418.93*h [/tex]

[tex] Height, h = \frac {8792}{418.93}[/tex]

Height, h = 20.99mm.

Therefore, the height of the cone is 20.99 millimeters.

Answer:

13.01d - 2.65

Step-by-step explanation:

DON'T IGNORE THIS PART!!!

Hmmm... in order to be able to solve these type of expressions and more complex ones, we need to know what like terms are in the first place.

Well, the best definition of like terms is: Terms that have the same exact variables.

Let's see the terms that have the same exact variables! They are 3.26d and 9.75d.

By the way, before we continue--I would like to mention something extremely important: 3.26d and 9.75d are positive, whereas -2.65 is negative (you know, the negative sign appears right before it).

Now, let's add 3.26d and 9.75d. It equals 13.01d.

Step-by-step explanation:

Answer:

X=50

Step-by-step explanation:

x is the angle

180 - x is its suplement

90 - x is its complement

(180 - x) - 3(90 -x) = 10

180 - x -270 +3x = 10

-90 + 2x = 10

2x = 100

X = 50

Answer:

We have,

3+4(w+5)

=31 Or, 3+20+4w

=31 or, 4w

=31−23

w=8/4

Thus, w comes out to be 2 .

Step-by-step explanation:

Hope it is helpful....

Answer:

w=2

Step-by-step explanation:

3 + 4(w + 5) = 31

distribute 4(w + 5)

4 x w = 4w

4 x 5 = 20

rewrite your equation

3 + 4w + 20 = 31

add like terms

3 + 20 = 23

rewrite equation

4w + 23 = 31

subract 23 on both sides

4w + 23 = 31

-23 -23

4w = 8

divide by 4 on both sides to get w by itself

4w = 8

4      4

w = 2
