Answer:

3 x 10= 30

Step-by-step explanation:

Round 3.1 to 3. Round 9.87 to 10. Plug numbers in.

Answer:

30.597

Step-by-step explanation:

3.1×9.87 (3 decimal places)

So, 31×987 = 30,597

Place the decimal places hence, 30.597

Answer:

1) 8/15

Step-by-step explanation:

When dividing by a number, multiply by its reciprocal.

2/5 ÷ 3/4

2/5 × 4/3

Answer:

no

Step-by-step explanation:

3^3=27

so 3^3+3^3+3^3=27+27+27=81

3^9=19683

Answer:

No it's not same because we cannot add degrees. 3^9 is much greater than 3^3+3^3+3^3.

27+27+27≠ 19, 683

81≠19,683

Answer:

C

Step-by-step explanation:

the "-" sign can't be true, because that would have turned the whole graph of x² upside-down. but it is not.

so, we need a positive sign for the x term.

and the whole graph is shifted to the right. so the functional value of x of F(x) is now the same that happened "earlier" (for smaller x) with G(x). so, the argument "x" is now reduced (by 3 units, as the graph is shifted right by 3 units) in the calculation compared to the original G(x) calculation.

therefore, the ...(x-3)... expression is right.

so, positive sign and "(x-3)" is only in C.

Given that :-

[tex]\leadsto[/tex]Remaining hours for which the job will last after first hour= (h-1)

Therefore,

Cost for subsequent hours = 30×(h-1)

Answer:

277 591.1 ft³

Step-by-step explanation:

First, use the formula for circumference to solve for the diameter.

Circumference = πd

295.3 = πd

295.3/π = d

94 ft = d

Then, divide the diameter by 2 to find the radius.

r = d/2

r = 94/2

r = 47 ft

Now, use the value of the radius with the given height in the formula for volume of a cylinder.

V = πr²h

V = π(47²)(40)

V = 277 591.1 ft³

Answer:

3x-3y+4

Step-by-step explanation:

Answer:

3x-3y+4

Step-by-step explanation:

x-3y+2x+4

Assume the coefficient of term x is 1, so: 1x-3y+2x+4

1x and 2x are the only like terms, so we combine them and the final answer is:

3x-3y+4

Answer:

Yes.

Step-by-step explanation:

The expression 2y + 6 could be used to denote the tree's height.

A number, a variable, or a mixture of numbers and variables, along with operation symbols, make up an expression. Two expressions joined by an equal sign form an equation.

Given, the height of a tree that began at 6 feet and increases by 2 feet per year. Let y represent the number of years

Expression = 2y + 6

Since the height of the tree starts at 6 feet thus positive 6 would be constant and it increases by 2 feet every year thus 2 would be the multiple of the variable that is y.

therefore, an Expression that represents the height of the tree would be 2y + 6.

Step-by-step explanation:

divide 35 by 2 and u get 17.5, this is in between 17 and 18 so that's why they are they consecutive numbers.

Answer:

123 + (456 + 789)

Step-by-step explanation:

since this is an addition problem, the parenthesis don't matter, and they can be put wherever you want.

(123 + 456) + 789

123 + 456 + 789

(123 + 456 + 789)

123 + (456 + 789)

technically, any of these would work, but I think the kind of answer the problem is looking for is;

123 + (456 + 789)

Answer:

Real analysis serves as the basis for measure theory, axiomatic probability, which follow to stochastic processes. Stochastic processes are used in finance, trading, computer and network simulations, modelling, manufacturing, quality control, etc

Answer:

a is D and b is C

Step-by-step explanation:

Slope is always with an x, b is always alone

Hey there!

Please remember that

Is y=4x-5 written in slope-intercept form (y=mx+b)? Sure! :)

Therefore, the slope, m, is 4, and the y-intercept, b, is -5.

Same with the second equation:

y=2/3-x

or

y=x-2/3

here, the y-intercept, b, is 2/3, and the slope, m, is -1.

Now, what's the equation of the line with a slope of 2 and a y-intercept of -7?

That's right, y=2x-7.

Hope everything is clear.

Let me know if you have any other questions!

Step-by-step explanation:

The reduced row echelon form* of ...

  [tex]\left[\begin{array}{ccc|c}4&5&-6&2\\-3&-2&7&-15\\-1&4&2&-13\end{array}\right][/tex]

is ...

  [tex]\left[\begin{array}{ccc|c}1&0&0&-3\\0&1&0&-2\\0&0&1&-4\end{array}\right][/tex]

which tells you the value of 'a' is -3.

_____

* Many scientific and/or graphing calculators and web sites can find the reduced row echelon form of a matrix for you. Or, for a single variable (such as 'a'), you can use Cramer's rule. That requires you compute two 3×3 matrix determinants. Again, there are many calculators, apps, and web sites that will make this calculation for you.

  [tex]a=\dfrac{\left|\begin{array}{ccc}2&5&-6\\-15&-2&7\\-13&4&2\end{array}\right| }{\left|\begin{array}{ccc}4&5&-6\\-3&-2&7\\-1&4&2\end{array}\right|}=\dfrac{147}{-49}=-3[/tex]

Answer:

0.3024

Step-by-step explanation:

Given the following :

Probability of breaking pinata on first hit = 0.58;

P(first hit break) = 0.58

P(does not break on first hit) = 1 - p(first hit break) = 1 - 0.58 = 0.42

P(2nd hit break) = p(first hit break) + 0.14 = 0.58 + 0.14 = 0.72

Hence, Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit

P(does not break on first hit) * p(2nd hit break)

0.42 * 0.72 = 0.3024

Answer:

105

Step-by-step explanation:

Assuming A^2 + B^2 = C^2:

C^2 = 4 + 3 = 7

So,

C^2 * 15 = 49(15) = 105

Note: Since the relationship between A, B, and C isn't known, it cannot be said for certain that 105 is the answer.

Step-by-step explanation:

there is no C in the first 2 equations. There is no A or B in the last expression. I do not think you can solve this.
