Answer: D) QR^2 = 20^2 + 27^2 – 2(20)(27) ⋅ cos 99°

Step-by-step explanation:

since you have the lengths of two sides and their included angle, you can use the law of cosines to solve for the missing side. let a, b, and c be the side lengths, and A be side a's respective opposite angle:

the law of cosines states that

a^2 = b^2 + c^2 - 2bc ∙ cosA

Answer:

168000

Step-by-step explanation:

5/14 to the son.

that leaves 9/14 of the total.

these 9/14 we need to split into 1/3rds, as 2/3 of these 9/14 go to the daughter, and then the remaining 1/3 of these 9/14 to the wife.

how do we do that ?

well, here it is simple, as we see right away that the numerator 9 can be easily split into 1/3rds (9/3 = 3).

but in general by multiplying. so 2/3 of 8/14 is

9/14 × 2/3 = 9×2 / 14×3 = 3×2 / 14 = 6/14

and then little surprising 1/3 is

9/14 × 1/3 = 9 / 14×3 = 3/14

now, we know, these 3/14 are 36000.

what we need to know is how much is 14/14 or 1/1 : the whole amount.

well, the easiest way in my opinion is now to bring it to 1/14 (by dividing by the numerator 3) and then multiply it by 14 (the denominator) to bring the sum to the whole (14/14).

it in total, multiply it with the reverse fraction : 14/3

36000 × 14/3 = 12000×14 = 168000

Answer:

2

Step-by-step explanation:

The average rate of change over [2, 8] is the change in the y-values over the change in the x-values.

[tex]\frac{f(8) - f(2)}{8 - 2}[/tex]

[tex]f(8) = 2(8) - 8 = 16 - 8 = 8[/tex]

[tex]f(2) = 2(2) - 8 = 4 - 8 = -4[/tex]

[tex]\frac{8 - (-4)}{8-2} = \frac{8 + 4}{8-2} = \frac{12}{6} = 2[/tex]

Answer:

-163.64..................

Answer:

n = 6

Step-by-step explanation:

To solve this you can use an equation such as:

[tex]\frac{2}{3} n+4=8\\\\[/tex]

We need to so for n. Subtract 4 from both sides to get the variable (n) alone. 4 - 4 and 8 - 4 equals:

[tex]\frac{2}{3}n=4[/tex]

So now we divide both sides by 2/3.

This now equals:

In f(x)=ax+b, 'a' is the slope and b is the initial value or y intercept

Given :

Given function is f(x)=ax+b

f(x)=ax+b is the linear equation

The graph of a linear equation is a line. The value of 'a' tell us the steepness of the line that is the slope of the line .

'b' is the initial value . when x=0, f(x)=a(0)+b

that is f(0)=b

So, 'b' is the initial value or y intercept.

The volume of the warehouse with the three dimensions is V = 1,316.224 cubic meters.

Given data:

To calculate the volume of the warehouse, you need to multiply its length, width, and height:

Volume = Length *  Width * Height

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Given the dimensions:

Length = 22.4 meters

Width = 11.3 meters

Height = 5.2 meters

Substitute these values into the formula:

Volume = 22.4 m × 11.3 m × 5.2 m

Calculate the result:

Volume = 1,316.224 m³

So, the volume of the warehouse is approximately 1,316.224 cubic meters.

Answer

(3.5 times 5.25) times 4

Step-by-step explanation:

then convert the decimal to a fraction.

The surface area is the total area occupied by the object. The surface area of the painted figure is [tex]440m^2.[/tex]

From the attached box, we have the following:

[tex]L = 20m[/tex] -- length

[tex]W = 10m[/tex] --- width

[tex]H = \frac 45 \times 5m = 4m[/tex] --- the painted height

Since the box has an open-top, the surface area is:

[tex]Area = LW + 2(WH + LH)[/tex]

So, we have:

[tex]Area = 20 \times 10 + 2 \times (10 \times 4 + 20 \times 4)[/tex]

[tex]Area = 200 + 2 \times (120)[/tex]

[tex]Area = 200 + 240[/tex]

[tex]Area = 440[/tex]

Hence, the painted area is [tex]440m^2.[/tex]

Answer:

Gordon will use 5/6 of the bag of cheese to make the entire recipe.

Step-by-step explanation:

We are given that Gordon makes 4/5 of a recipe with 2/3 bag of cheese.

And we want to determine what fraction of the bag of cheese Gordon will use to make the entire recipe.

We can write the following ratio:

[tex]\displaystyle \frac{\dfrac{2}{3}\text{ bag of cheese}}{\dfrac{4}{5}\text{ recipe}}[/tex]

Find the unit rate. Multiply both layers by 5/4:

[tex]\displaystyle \frac{\dfrac{2}{3}\text{ bag of cheese}}{\dfrac{4}{5}\text{ recipe}}\times \frac{\dfrac{5}{4}}{\dfrac{5}{4}}[/tex]

Multiply:

[tex]\displaystyle \frac{\dfrac{5}{6}\text{ bag of cheese}}{1 \text{ recipe}}[/tex]

In conclusion, Gordon will use 5/6 of the bag of cheese to make the entire recipe.

Answer:

y = 3x + 19

Step-by-step explanation:

Apply point-slope form. Our point (y1, y2) is (-4, 7) and our slope (m) is 3. The slope of y = 3x - 5 is 3 because it is "m" in y = mx + b. Parallel lines have the same slope.

y - y1 = m(x-x1)

y - 7 = 3(x-(-4))

y - 7 = 3(x+4)

y - 7 = 3x + 12

y = 3x + 19
