Answer:

55 cm²

Step-by-step explanation:

Area of rectangle is 9 × 7 = 63 cm²

Area of write angled triangle is [tex]\frac{1}{2}[/tex] (7 - 3)(9 - 5) = 8 cm²

The area of shaded region is 63 - 8 = 55 cm²

Answer:

Solving the equation [tex]\frac{a^2-b^2}{2+d^3}[/tex] by putting a=6, b=4 and d=1/2 we get [tex]\frac{160}{17}[/tex]

Step-by-step explanation:

We are given formula: [tex]\frac{a^2-b^2}{2+d^3}[/tex]

and values a=6, b=4 and d=1/2

We need to put the values of a, b and d in the given equation [tex]\frac{a^2-b^2}{2+d^3}[/tex] and find their result

Putting values in the equation:

[tex]\frac{a^2-b^2}{2+d^3}\\=\frac{(6)^2-(4)^2}{2+(\frac{1}{2})^3}\\=\frac{36-16}{2+\frac{1}{8}}\\=\frac{20}{\frac{2*8+1}{8}}\\=\frac{20}{\frac{17}{8}}\\=\frac{20*8}{17}\\=\frac{160}{17}[/tex]

So, solving the equation [tex]\frac{a^2-b^2}{2+d^3}[/tex] by putting a=6, b=4 and d=1/2 we get [tex]\frac{160}{17}[/tex]

Answer:

The required distance away from the foot of the tree is 238.0 feet.

Step-by-step explanation:

The height of the redwood tree = 340 feet, and the angle of elevation to its top = [tex]55^{o}[/tex].

let the required distance be represented by x, applying the appropriate trigonometry function, we have;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

Tan [tex]55^{o}[/tex] = [tex]\frac{340}{x}[/tex]

⇒ x = [tex]\frac{340}{Tan 55^{o} }[/tex]

      = [tex]\frac{340}{1.4282}[/tex]

      = 238.062

x = 238.0 feet

The required distance away from the foot of the tree is 238.0 feet.

Complete question is;

A truck driver travels from a distributor to a retailer every week. The driver records the distance that he is from the retailer at different times during his trip. After several weeks of collecting data, the driver creates a scatter plot of the data. The best–fit line is y = 73.6 – 67.8x, where x is the number of hours spent driving and y is the distance, in miles, from the retailer.

Which of the following statements are true? Select all that apply.

The distance from the retailer increases with time.

The distance from the retailer decreases with time.

The distributor is 67.8 miles away from the retailer.

The distributor is 73.6 miles away from the retailer.

The truck is traveling at a rate of 67.8 miles per hour.

Answer:

B: The distance from the retailer decreases with time.

Step-by-step explanation:

Formula for best fit line is;

y = mx + b

Where;

m is slope

b is y-intercept

We are told that the best–fit line is y = 73.6 – 67.8x

This can be written as;

y = -67.8x + 73.6

This means the slope is negative and when x = 0, y = 73.6 which is the y-intercept.

We are told that x is the number of hours spent driving and y is the distance, in miles, from the retailer.

Since we have a negative slope, it means that y is decreasing with increasing values of x.

Thus, we can say that the distance from the retailer decreases with time.

Answer:

X=8

Step-by-step explanation:

17x-4=12+15x

add 4 on both sides to get

17x=16+15x

now subtract 15x on both sides to get

2x=16

divide by 2 on both sides

you get

x=8

Answer:

The number of places correctly identified is 110 places

Step-by-step explanation:

The number of places he correctly identified will be;

11 + 4 + 86 + 9 = 110 places

By using compatible numbers, we refer to the fact that she use an estimate by making sure each of the numbers are closer to the nearest 10th or 5

so 4 will be 5

11 will be 10

86 will be 85

9 will be 10

Adding all of these together, we have

5 + 10 + 85 + 10 = 110

The correct option is option C i.e., (1,3).

It is given that a circle has the points (4, 2), (-2, 2), (-1, 4), (1, 1), (1, 3), (2, -3).

We have to check which ordered pair from given options is correct.

What do you mean by domain and ranges of a function ?

The domain is set of all values for which the function is defined and the range of the function is set of all values that function takes.

As per the question ;

A circle has the points ;

(4, 2), (-2, 2), (-1, 4), (1, 1), (1, 3), (2, -3).

We know that ;

A function is just like a machine that gives an output for a given unique input. The input given to the function is called the domain whereas the output of a function is called its range.

Also ;

The domain is the independent variable and is represented by the 'x' coordinate and range depends on the values of the domain and is represented by the 'y' coordinate.

Now ; check for relation.

Here ; the ordered pairs (1, 1) and (1, 3) have the same input. So if we remove either of them , it will make the relation as a function.

So;

The correct option is C.

Thus , the correct option is option C i.e., (1,3).

Answer:

The equation -x + 6y = -7 does not represent direct variation.

Step-by-step explanation:

Let us solve the question

∵ The equation is -x + 6y = -7

→ Substitute x by 0 to find the value of y-intercept

∵ x = 0

∴ 0 + 6y = -7

∴ 6y = -7

- Divide both sides by 6 to find y

∴ y = [tex]-\frac{7}{6}[/tex]

∴ The y-intercept of the equation is (0, [tex]-\frac{7}{6}[/tex] )

∵ The y-intercept of the direct variation is (0, 0)

∴ The equation -x + 6y = -7 does not represent direct variation.

Answer:

25 1/2 square meters remaining

Step-by-step explanation:

Total area of the pool deck=76 1/2 square meters

He painted 2/3 of the deck before stopping for lunch

Total painted=2/3 of 76 1/2

=2/3*153/2

=306/6

=51 square meters

Total remaining=Total area - total painted area

=76 1/2 - 51

=153/2 - 51

=153-102/2

=51/2

=25 1/2 square meters remaining

How to solve your question

Your question is 1/2(4x-2)=6x-3

Solve

1.Combine multiplied terms into a single fraction

1/2(4x-2)=6x-13

1(4x-2) divided by 2 =6x-13

2.Multiply by 1

3 Subtract 6x from both sides of the equation

4.Simplify

5.Multiply all terms by the same value to eliminate fraction denominators

6.simplify

7.Add 2 to both side of equation

8.Simplify

9.Divide both sides of the equation by the same term

10.Simplify

Step-by-step explanation:

Combine multiplied terms into a single fraction

1/2 (4x-2) / 2 = 6x - 13

1 (4x -2) /2 = 6x -13

Multiply by 1

1 (4x - 2) / 2 = 6x - 2

4x - 2 / 2 = 6x-13

Subtract 6x from both sides of the equation

4x - 2 / 2 = 6x - 3

4x - 2 /2 - 6x =6x -13 -6x

Simplify

Combine like terms

4x -2 /2 -6x = -13

Multiply all terms by the same value to eliminate fraction denominators

4x -2 /2 -6x = -13

2 (4x-2 /2 -6x) =2(-13)

Simplify

Answer:

Step-by-step explanation:

Answer:

(x + 8)² = 36

Step-by-step explanation:

When you are trying to complete the square and the equation already has a constant, you add or subtract that value to the other side of the equation so you can cancel it out.

x² + 16x + 28 = 0

x² + 16x + 28 - 28 = 0 -28

x² + 16x = -28

Now, you find ([tex]\frac{b}{2}[/tex])² (divide b by 2 and raise the quotient to the second power). Half of 16 is 8, and 8² is 64. Add 64 to both sides.

x² + 16x + 64 = -28 + 64

x² + 16x + 64 = 36

Now, you just factor the equation on the left. To factor it, you will always use the number you got to make the constant, which in this case is 8.

(x + 8)² = 36

Answer:

98 grams

Step-by-step explanation:

The simplest way to think about this is that the half life has elapsed 3 times, so you need to take the initial mass and divide it by 2 3 times, so 784/2/2/2 or 784/8 which is 98

Let's do long division. I've uploaded the file for the work.

Answer:

v=99

Step-by-step explanation:

This is somewhat like a ratio problem. So, when v is 36, g is 4. We can simplify this. So, if we divided g by 4 we get one, and if we divide v by 4 we get 9. So, we have 1:9 ratio of g to v. If g is 11, then we multiply the 1 by 11 and the 9 by 11 also. Therefore, v is 99

Answer:

y = -5x - 8

Step-by-step explanation:

Take the points (-5,-4) and (0,-3) plug them into this formula to get the slope.

[tex]\frac{y2 - y1 }{x2 - x1}[/tex]

Now plug in your points

[tex]\frac{-3 - (-4)}{0 - (-5)} \\\\\frac{1}{5}[/tex]

Since you're slope is 1/5 the slope of the perpendicular line is going to be the totally opposite -5 is the slope of the perpendicular line.

Now plug in -5 and the point (-2,2) into y = mx + b to get the y-intercept

2 = -5(-2) + b (b represents the y-intercept)

2 = 10 + b (subtract 10 from both sides)

-8 = b

The perpendicular line looks like this y = -5x - 8

Answer:

s : l = 24 : 35

Step-by-step explanation:

Let

Socks weight = s

Princess weight = p

Luna's weight = l

The ratio of Socks weight to princess weight is 4:5

s : p = 4 : 5

s / p = 4 / 5

The ratio of princesses weight to Luna's weight is 6 :7

p : l = 6 : 7

p / l = 6 / 7

What is the ratio of socks weight to Luna's weight

Multiply both given ratios

s / p * p / l = 4 / 5 * 6 / 7

p cancel out

s / l = 24 / 35

s : l = 24 : 35

Ratio of socks weight to Luna's weight is 24 : 35
