What Is The Surface Area Of This Wedge

Answers

Answer 1

Answer:

84 ft

Step-by-step explanation:

triangle= 1/2bh

rectangle or square = bh

so 1/2(4)3=6

6 times 3= 18

1/2(4)3= 6

4 times 6 = 24

5 times 6 = 30

now you add them all up

6 + 18 + 6+ 24+ 30 =

Answer 2

The Surface area of this wedge is 84 square ft.

What is Surface Area?

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area.

To find the Surface are we will find the area of each part individually.

We have two triangle and 3 rectangles.

So, area of Triangle

= 1/2 b h

= 1/2 x 4 x3

= 6 square ft

Area of rectangle

= l w

= 6 x 3

= 18 square ft

Area of 2 rectangle

= l w

= 4  x 6

= 24 square ft

and, area of 3rd rectangle

= 5 x 6

= 30 square ft

So, the Surface area of Figure is

= 6 + 18 + 6 + 24 + 30

= 84 square ft

What is the total surface area of the rectangular prism in square meters?

The net of a rectangular prism and its dimensions are shown in the diagram.What is the total surface

Answers

Answer:

642.96

Step-by-step explanation:

To find the surface area"

\(SA=2lw+2lh+2wh\)

Insert measurements into the equation:

\(SA=2*17\frac{2}{5}*3+2*17\frac{2}{5}*13.2+2*3*13.2\)

Now to go through the very tedious steps of actually solving the equation (we got this!)

\(2*17\frac{2}{5}*3= 104.4\)\(2*17\frac{2}{5}*13.2=459.36\)\(2*3*13.2=79.2\)

Next: Addition

\(104.4+459.36=563.76\)\(563.76+79.2=642.96\)

And we have our answer!

What is Unitary method?

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Steps to Use Unitary Method

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

total books = 1500

So, cartoons of 10 needed

=1500 / 10

=150 cartoons

and, cartoons of 15 needed

=1500/15

=100 cartoons

To find the mean we add all of the scores together and divide it by how many scores there were:

\(\frac{5+2(6)+4(7)+8(8)+5(9)}{20}\)

After simplifying, we get:

\(\frac{140}{20} =7\)

So the mean is 7.

To find the median we order the scores of them from least to greatest:

\(5,6,6,7,7,7,7,8,8,8,8,8,8,8,8,9,9,9,9,9,\)

We see that the number in the middle is 8, so the median is 8.

The mode is obviously 8, because it appears most frequently.

The range is the highest score subtracted from the lowest score, or 4.

How far did I travel to reach my destination on each day of my three-day Trip?
a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination.
b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination.
c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.

Answers

The total distances you traveled to reach your destination on each day of your three-day trip are as follows:

a) Day 1 = 40 miles

b) Day 2 = 30 miles

c) Day 3 = 11 miles.

How the total distances are determined:

The total distances are determined using proportions.

Proportion refers to the fractional value of the whole number or quantity.

a) Day 1:

The fractional distance traveled = ⁵/₈

The remaining distance to travel = 15 miles

15 miles = ³/₈ (1 - ⁵/₈)

Proportionately, the total distance = 40 miles (15 ÷ ³/₈)

b) Day 2:

The distance traveled = 18 miles

The remaining distance to travel = ²/₅

The distance traveled = ³/₅ (1 - ²/₅)

³/₅ = 18 miles

Proportionately, the total distance = 30 miles (18 ÷ ³/₅)

c) Day 3:

The distance traveled = ⁵/₁₁

The distance to travel = 6 miles

The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)

Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

Write an equation in standard form of the line that passes through (−6,−10) and has the slope m=1/6.

Answers

Step-by-step explanation:

y-b=m(x-a)

y--10=1/6(x--6)

y+10=1/6(x+6)

6y+60=1(x+6)

6y+60=1x+6

6y=1x-54

y=1/6x-54/6

y=1/6x-9

The  equation of line is y= 1/6x - 9.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

slope= 1/6

and, passes through (−6,−10)

Now, using slope intercept form

y- a =m (x- b)

y - (-10)= 1/6(x -(-6))

y + 10= 1/6( x + 6)

y + 10 = 1/6x + 1

y= 1/6x - 9

Hence, the equation of line is y= 1/6x - 9.

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)

Answers

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.
