Answer:

[tex]v=s-u+t[/tex]

Step-by-step explanation:

Hi there!

[tex]s=u-t+v[/tex]

Our goal is to isolate v on one side of the equal sign.

Subtract u from both sides:

[tex]s-u=u-t+v-u\\s-u=-t+v[/tex]

Add t to both sides to isolate v:

[tex]s-u+t=-t+v+t\\s-u+t=v\\v=s-u+t[/tex]

Answer:

Accuracy is how close a measured value is to an accepted value. Precision is how close measurements are to one another. To make measurements, you have to evaluate both the accuracy and the precision to get a correct value.

Answer:

6

Step-by-step explanation:

[tex]a + b + c = 20[/tex]

[tex]a + b = 14(i)[/tex]

Putting value (a + b) in the above equation

[tex]14 + c = 20[/tex]

[tex]c = 20 - 14[/tex]

[tex]c = 6[/tex]

Answer: x = 5 or x = -4

Step-by-step explanation:

Given equation

x² - x = 20

Subtract 20 on both sides

x² - x - 20 = 0

Cross factorize the equation

x          -5

x          4

Factorize the equation

(x - 5) (x + 4) = 0

[tex]\boxed{x=5}[/tex] or [tex]\boxed{x=-4}[/tex]

[tex]\\ \sf\longmapsto 22\div 2[/tex]

[tex]\\ \sf\longmapsto 11[/tex]

Answer:

Step-by-step explanation:

All of these numbers can be divided by 2, 3, 5, 7, 11, 13...

There is no whole number if you want to divide each number.

121 only goes into 1, 11, and 121. No other numbers have 11

45/2 = 22.5

45/3 = 15

45/5 = 9

2470/2 = 1235

2470/3 = 823.33333...

2470/5 = 494

121/2 = 60.5

121/3 = 40.33333...

121/5 = 24.2

Answer: 4 months

Step-by-step explanation:

$75 + $152X = 683

That's the equation you need to set up, with X being the number of months.

To solve, first subtract 75 from both sides.

$152x = 608

Then, divide each side by 152

X = 4

The answer is 4 months.

Answer:

[tex]y=3x-4[/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 (the value of y when x=0)

1) Determine the slope (m)

[tex]m=\displaystyle\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

On the graph, two points are highlighted for us: (0,-4) and (2,2). Plug these into the formula:

[tex]m=\displaystyle\frac{2-(-4)}{2-0}\\\\m=\displaystyle\frac{2+4}{2}\\\\m=\displaystyle\frac{6}{2}\\\\m=3[/tex]

Therefore, the slope of the line is 3. Plug this into [tex]y=mx+b[/tex]:

[tex]y=3x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=3x+b[/tex]

Recall that the y-intercept occurs when x=0. Given the point (0,-4), the y-intercept is therefore -4. Plug this into [tex]y=3x+b[/tex]:

[tex]y=3x+(-4)\\y=3x-4[/tex]

I hope this helps!

Answer:

B. 2³(3 x 5² + 2²)

Step-by-step explanation:

2³(3 x 5² + 2²)

Step 1. Simplify the exponents

8(3 x 25 + 4)

Step 2. Multiply 3 and 25

8(75 + 4)

Step 3. Add 75 and 4

8(79)

Step 4. Multiply

632

Answer:

Option B. 2³(3 x 5² + 2²) is correct

Step-by-step explanation:

2³(3 x 5² + 2²)

First of all multiply the exponents

8×(3×25+4)

Then do the multiplication of 3 and 25

8×(75+4)

Now add the following numbers in the bracket

8×(79)

And the last multiply the following numbers

8×79

632

[Hence, the expression 2³(3 x 5² + 2²) is equal to 632. ]

Step-by-step explanation:

One gallon = 15,140 drips

One liter = 4,000 drips

The ingredients that should be used will be ( 50 / 9 ), ( 5 / 3 ), and ( 10 / 9 ).

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that three liquids are to be mixed in the ratio of 5:3:1.and their total is ten liters. The quantity of each part will be calculated as:-

Let the ratio is L₁ = 5x, L₂ = 3x and L₃ = x.

5x + 3x + x = 10

9x = 10

x = 10 / 9

The fraction of each part will be calculated as:-

5x = 5 x { 10 / 9 ) = 50 / 9

3x = 3 x ( 10 / 9 ) = 10 / 3

x = 10 / 9

Therefore, the ingredients that should be used will be ( 50 / 9 ), ( 5 / 3 ), and ( 10 / 9 ).

Answer:

(SS,SG,GS,GG) Probability 0.25

Step-by-step explanation:

i don't know how to do this

Heyo!

So, first things first:

Based on the data shown, it appears that Cameron has 1/4 a chance to really recieve any combo of the following. Hence, he can get SS, SG, 6S, GG. So, each chance he picks, he has a 0.25 chance of probably recieving any of the combo. So, the outcome order is (SS, SG, GS, GG) and the probability for each is 0.25.

It hard to really describe how to write it out without an image, but I hope this helps! Pls, lmk if it does! Good luck!
