Answer:

[tex]8 + x = 2 + 8 \\ 8 + x = 10 \\ x = 10- 8 \\ \\ x = 2 \\ then8 + 2 = 2 + 8 \\ thank \: you[/tex]

Answer:

2

Step-by-step explanation:

8 + 2 = 10, so basically, 10 - 8 = 2. Meaning the missing number to when 8 is added to something to equal 10, would be 2.

Answer:

let t be winning time     t < 7.09 seconds

Step-by-step explanation:

let's first order the times from least to greatest:

7.09, 7.40, 7.75, and 7.86

Now, in order to have the winning time, the last runner must have a time less than the fastest runner so far. So, the winning time is less than 7.09 seconds.

Make sure to add units. I know that my teachers are REALLY picky about that, though yours may not care.

Answer:

first statement

Step-by-step explanation:

64 < 77 < 81 , then

[tex]\sqrt{64}[/tex] < [tex]\sqrt{77}[/tex] < [tex]\sqrt{81}[/tex] , that is

8 < [tex]\sqrt{77}[/tex] < 9

Thus [tex]\sqrt{77[/tex] is to the left of 9 on the number line

Answer:

Olga's mistake: She did not multiply [tex]\frac{1}{4}[/tex] and [tex]\frac{1}{3}[/tex] in the beginning

Step-by-step explanation:

The main problem is that when a number is outside of the parentheses on the left side, then you have to multiply that number, in this case [tex]\frac{1}{4}[/tex], by both numbers in the parentheses. After that, continue solving the problem as you usually would. Hope this helped!

Answer:

50 gallons of red

30 gallons of blue

Step-by-step explanation:

5 parts of the whole must be red, 3 parts of the whole must be blue, and there are 5+3=8 parts in total.

therefore, 1 part = 80/8 = 10 gallons

red : 5 parts

5×10 = 50 gallons

blue : 3 parts

3×10 = 30 gallons

J (0 , -10)

gradient/slope(m) = 2.

We're asked to find K if K is the X- Intercept.

At the x intercept... the corresponding y value is zero. This concept should be pretty clear.

Reason is...

At the Point where the line touches the x axis...If you trace the y value... It will be at point zero(0).

With this Knowledge

We're able to interprete that the points of K is

(x" , 0)

Where x" represents the x coordinate of K

So

J ( 0, - 10)

K ( x" , 0)

m= 2.

Applying the Gradient/Slope Formula

m = y₂ - y₁/x₂ - x₁

x₁ = 0 y₁ = -10

x₂ = x" y₂ = 0

Substituting

2 = 0 - ( -10)/ (x" - 0)

2 = 10/x"

x" = 10/2

x" = 5.

Coordinates of Point K is ( 5 , 0).

THIS IS YOUR ANSWER!.

Total Time Taken = 16secs

10a). We're asked to calculate the rate of speed change for the first 5secs.

This is another way of saying "Calculate Acceleration" in the first 5sec of Motion.

Why?

Acceleration is the rate of change of speed or the rate at which speed changes.

acceleration = v - u/t

where v = Final Speed

u = initial Speed.

Looking at the graph

You see that

Initial speed(u) = 1m/s

Final Speed(v) = 9m/s

t = 5secs

Acceleration = 9 - 1/ 5

a = 8/5

a = 1.6m/s².✅

10b)

We're asked to calc "t" from the graph.

Given that the acceleration at "t" untill 16sec(end of motion) is 2m/s².

This simply means that Constant Acceleration was held from "t" to the end of the Motion.

Do not confuse Constant Acceleration for Constant Velocity.

At Constant Velocity... Acceleration is zero(0)

At Constant Acceleration...Velocity Changes Uniformly or at the same rate each second and this is what we're dealing with in this question.

Taking the same step as we used in calculating acceleration above

Given a= 2m/s²

a = v - u/∆t

Where ∆t means time change or difference.

From "t" to 16

The change in time is 16 - "t"

2 = 21 - 9/( 16 - t)

2 = 12/16-t

16-t = 12/2

16 - t = 6

t = 16 - 6

t = 10secs.✅

Have a great Day!.

Answer:

The three numbers are 29, 31, and 33.

Step-by-step explanation:

Let's imagine that the three consecutive odd integers are 2x−1, 2x+1, and 2x+3. And we are told the sum is 93 right? So, let's equal the three numbers to 93.

2x − 1 + 2x + 1 + 2x + 3 = 93

6x + 3 = 93

     -3     -3

-----------------

6x = 90

/6    /6

----------------

x = 15

Now, plug in x into 2x−1, 2x+1, and 2x+3 to find the three numbers.

2x − 1                   2x + 1                 2x + 3

2(15) - 1                2(15) + 1             2(15) + 3

30 - 1                    30 + 1                 30 + 3

= 29                      = 31                      = 33

Answer:

D because it costs less for 7 hours

Answer:

The company that would give you the best deal would be Company D.

Step-by-step explanation:

Company A:

First you set up as an equation.

y=25x+50

I used 25x because 25 represents the hourly rate and x represents the hour it increases.

y=25(7)+50

We have to substitute 7 in for x because it says "If you had planned for 7 hours".

Multiply 25 and 7. You should get 175.

y=175+50

Add 175 and 50. You should get 225.

y=225.

You do the same thing for the rest of the problems.

Company B:

y=30x+40

y=30(7)+40

y=210+40

y=250

Company C:

y=20x+60

y=20(7)+60

y=140+60

y=200

Company D:

y=5x+150

y=5(7)+150

y=35+150

y=180

The company that would give you the best deal would be Company D.

Answer:

20

Step-by-step explanation:

The distance formula is just

[tex]d = \sqrt{(x2-x1)^2+(y2-y1)^2} \\d = \sqrt{(-16-4)^2+(0)^2}\\d = \sqrt{(-20)^2} \\d = \sqrt{400} \\d = 20[/tex]

Step-by-step explanation:

Hi there!

According to the question;

nth term (tn) = 3n+8

a).

T1 = 3*1+8

= 11

b).

t7 = 3*7+8

= 29

c).

t14 = 3*14+8

= 50

Therefore, t1 = 11, t7 = 29, t14 = 50.

Hope it helps!

Answer:

11, 29, 50

Step-by-step explanation:

To find the appropriate term , substitute the term number into the rule, that is

(a) t₁ = 3(1) + 8 = 3 + 8 = 11

(b) t₇ = 3(7) + 8 = 21 + 8 = 29

(c) t₁₄ = 3(14) + 8 = 42 + 8 = 50

Answer:

[tex]y=6x-5[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept

We're given that the slope is 6. Plug this into [tex]y=mx+b[/tex] as m:

[tex]y=6x+b[/tex]

Now, to solve for the y-intercept, plug in the point (1,1) and solve for b:

[tex]1=6(1)+b\\1=6+b\\b=-5[/tex]

Therefore, the y-intercept of the line is -5. Plug this back into [tex]y=6x+b[/tex]:

[tex]y=6x+(-5)\\y=6x-5[/tex]
