Answer:

Uhm I think you need to like times the 10 to the 56? erm yeaaaaaaa SOrry if you get it wrong

Step-by-step explanation:

Answer:

1:2

Step-by-step explanation:

56*10= 560

34+56= 90

90*10= 900

X is about 2 times the size of W so it would be

1:2 (W:X)

I think i am right, i may be wrong i haven't exactly learned this yet, i am just going off by what i know. sorry if i am wrong

Answer:

No, the student is not correct. The correct expression is 9(n+13).

Step-by-step explanation:

"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.

Answer:

Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.

Answer:

3) cos A = 12/13 = 0.9231

1) sin A = 5/13 = 0.3846

2) tan C = 12/5 = 2.4000

plug y = 6 on to the equation y =x + 5

=> 6 = x +5

=> x = 1

Answer:

(-3, -4)

Step-by-step explanation:

y= -4

so you plus y in for the y=2x+2 equation where you get x=-3

[tex]\huge\text{Hey there!}[/tex]

[tex]\large\text{If y = -4 then SUBSTITUTE it into the EQUATION}[/tex]

[tex]\large\text{-4 = 2x + 2}[/tex]

[tex]\large\text{TURN the EQUATION}[/tex]

[tex]\large\text{2x + 2 = -4}[/tex]

[tex]\large\text{SUBTRACT by 2 to BOTH SIDES}[/tex]

[tex]\large\text{2x + 2 - 2 = -4 - 2}[/tex]

[tex]\large\text{CANCEL out: 2 - 2 because that gives you 0}[/tex]

[tex]\large\text{Keep: -4 - 2 because it helps us solve for x}[/tex]

[tex]\large\text{2x = -6}[/tex]

[tex]\large\text{DIVIDE by 2 to BOTH SIDES }[/tex]

[tex]\mathsf{\dfrac{2x}{2}=\dfrac{-6}{2}}[/tex]

[tex]\large\text{CANCEL out: }\mathsf{\dfrac{2}{2}}[/tex] [tex]\large\text{because that gives you 1}[/tex]

Answer:

40.4%

Step-by-step explanation:

Given data

Initial depth= 5feet

Final depth= 5-3.2+6.6= 8.4feet

Hence the percent change

% change= FInal-initial/final*100

% change= 8.4-5/8.4*100

% change= 3.4/8.4*100

% change= 0.404*100

% change=40.4%

Hence the percent change is 40.4%

Percentage change between two measurement is the proportion of

change between the measurement expressed as a percentage.

The percentage change in the river depth in in 1848 is 106.25%

Reasons:

The given parameters are;

The depth of the river in the year 1846 = 5 feet

In the year 1847, the depth = 3.2 feet

In 1848 the depth = 6.6 feet

[tex]\displaystyle Percentage \ change = \mathbf{ \frac{Current \ depth - Previous \ depth}{Previous \ depth}}[/tex]

Which gives;

[tex]\displaystyle Percentage \ change = \frac{6.6 -3.2}{3.2} \times 100 = \mathbf{106.25 \%}[/tex]

The percentage change in the river depth in the current period = 106.25%

Answer:

ecall that 6 + 6 + 6 = 6 × 3

Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.

Similarly,

6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42

Still by the same token,

2 + 2 + 2 + 2 = 2 × 4

In algebra, 2 × 4 can be written as (2)(4)

You can think of this as four groups of 2.

This situation is shown in the number line below.

You basically start at 0 and count by 2's until you have put four 2's on the number line. You end up at 8 and 8 is positive.

Answer:

This quadratic has two unequal, imaginary roots.

Step-by-step explanation:

y = 3x^2 + 8 is a quadratic function, and (like all quadratics) it has two roots.  In this case they happen to be different (unequal), as well as imaginary.

Setting y = 3x^2 + 8 = 0, we get:

3x^2 = -8, or

x^2 = -8/3

Taking the square root of both sides, we get

x = ±i√(8/3) (2 imaginary roots)

Answer:

  C  3x +1 = y

Step-by-step explanation:

x-values increase by 1 from row to row.

y-values increase by 3 from row to row.

The slope of the linear function is the ratio of the y-increase to the x-increase:

  m = ∆y/∆x = 3/1 = 3

The only offered choice with an x-coefficient of 3 is ...

  C  3x +1 = y

__

If you check this against the table entries, you find it fits.

  3(1) +1 = 4

  3(2) +1 = 7

and so on.

Step-by-step explanation:

Answer:

A. Add -2 to both sides

Step-by-step explanation:

The reason you need to add -2 to both sides is because if you add -2 to -2 it cancels out and you are left with x=18. But you need to add -2 to 18 too because them the equation won't be equal anymore.

Answer:

10.

Step-by-step explanation:

Lets define a square root.  A square root is a number multiplied by itself.        10 x 10 = 100, this is the closest we can get to 105, therefore 10 is the answer.
