7.486 to 7.5 Place value

Answer:

A) 2

Step-by-step explanation:

The square root of 4 is 2 because 2 x 2 = 4.

The equation says x = 4, and what your trying to solve is the square root of that, not the root. The root to 4 would be 16 if it was reversed.

Answer:

10

Step-by-step explanation:

Use the PEMDAS rule.

20 - 3 * 6 + 8

= 20 - 18 + 8

= 20 - 10

= 10

When we carry out the operation 20 - 3 × 6 + 8 the result obrained is 10

The meaning of BODMAS is given below:

The above pattern tells us exactly what sign to carry out 1st when we have more than one signs in an expression.

20 - 3 × 6 + 8

Carry out multiplication

20 - 18 + 8

Carry out addition

20 - 10

Carry out subtraction

Answer:

The rectangle above shows its dimensions. Find the perimeter.

First, substitute the values for the width

(W)

and the length

(L)

into the perimeter formula.

P=2(12)+2(9)

Next, complete the multiplication and addition to find the perimeter.

PPP===2(12)+2(9)24+1842

The answer is 42.

The perimeter of the rectangle is 42 inches.

Area is the amount of square units inside the figure. Area is found by multiplying the

length×width

. The formula for finding the area of a rectangle is:

A=L×W

You can use the dimensions from the rectangle above to find the area of this rectangle.

First, fill the values for

L

and

W

into the formula for area.

AA==L×W12×9

Next, solve for the area by multiplying.

AA==12×9108

The answer is 108.

The area of the rectangle is

108 in2

.

Notice that the unit of measurement for area is squared. That is because you multiplied a unit measure times itself:

in×in=in2

. Area is always written in square units.

You can also find the perimeter and area of a square. Remember that a square has four equal sides given the symbol

s

. You can use the following formula for finding the perimeter of a square:

P=4s

Let’s look at an example.

A rectangle has a length of 12 feet and a perimeter of 72 feet. Write and solve an equation to determine the width of the rectangle.

First, substitute the values for the perimeter

(P)

and the length

(L)

into the perimeter formula.

72=2(12)+2W

Next, complete the multiplication.

72=24+2W

Then, subtract 24 from both sides to get your variable alone on the right side.

72−2448==24−24+2W2W

Then, multiply both sides by the reciprocal of 2 to isolate your variable.

12×481482W===12×2W1W24

The answer is 24.

The width of the rectangle is 24 feet.

The width of the rectangular garden is 5 2/3 feet

We have the following information available from the question is:

The area of a rectangle is 53 5/6 square feet

and, the length (L) of the garden is 9 1/2 feet

We have to find the width (W) of the rectangle.

Now, According to the question:

We know that :

The area of rectangle = L × W

Plug all the values in above formula:

53 5/6 = 9 1/2 × W

323/6 = 19/2 × W

[tex]W=\frac{323(2)}{6(19)}[/tex]

W = 17/3

17/3 as a mixed number would be 5 2/3.

Hence, The width of the rectangular garden is 5 2/3 feet

Answer:

The answer should be D

Step-by-step explanation:

sorry if it's wrong, I just did this test the other day and I forgot if I got it right.

The rational function that is represented by the given graph is [tex]f(x) = \frac{4x - 8}{x^{2} +x-6}[/tex]

Rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials.

We need to find out which  rational function is represented by this graph.

Firstly, we see that graph does not exist at x = -3 and x = 2.

Thus, (x+3) and (x-2) cannot be equal to 0.

(x + 3)(x - 2) = x² + x - 6

Thus, the denominator of the function is x² + x - 6.

So, our solution can be B. or D.

We can also see that there is a circle over the graph at x = 2. This means that f(x) is undefined at x = 2. It is possible only if f(x) = ∞/∞ or 0/0 at x = 2.

On putting the value of x = 2 in both B. and D., we find that in D. f(x) = 0/0 at x = 2.

[tex]f(2) = \frac{4*2 - 8}{4 + 2 - 6} = \frac{0}{0}[/tex]

$212

Step-by-step explanation:

to get this answer, you must find what 6% of 200 is, which can be calculated using this little equation here

percentage/100 x original price = sales tax

6/100 x 200= 0.06 x 200= 12

this gives you the sales tax, or the amount of money that was added onto the original price, all that's left to do is to add, so original price + sales tax

200+12= $212

A graph may or may not represent a function.

The true statement is: (b) Yes, the graph passes the vertical line test.

The vertical line test is used to determine if a graph represents a function or not.

When a vertical line is drawn through the graph, the line would only intersect with the curve at a point.

This means that:

The graph represents a function.

Hence, option (b) is true
