Answer:
116 km squared
Step-by-step explanation:
When you get crazy shapes like this, try and look for the basic ones inside (i.e. triangles, rectangles, etc.) I can find one big triangle and two rectangles, one small and one larger. Vide the attatchment for reference.
Step 1. Find the missing variables, x, y, and z
y = 2
x = 6 - 2 = 4
z = 8 + (4) + 2 = 14
Step 2. Find the area of each shape
Triangle:
Area = bh/2 = (8 x 14)/2 = 56 km sq
Big rectangle:
Area = bh = 8 x 6 = 48 km sq
Small rectangle:
Area = bh = 2 x 6 = 12 km sq
Step 3. Add all the areas together
56 + 48 + 12 = 116 km sq

A cylinder has volume 45 pie and radius 3. What is its height?
Answer:
5 units
Step-by-step explanation:
The volume of the cylinder is the area of the circle multiplied by it's height. Therefore, the volume of the cylinder is πr² × h, which when simplified, gives us πr²h. Let's substitute the volume and the radius in the formula to find the height.
⇒ πr²h = Volume of cylinder
⇒ (π)(3²)(h) = 45π
Now, simplify the equation to evaluate the area of the cylinder.
⇒ (π)(3²)(h)/(3²)(π) = 45π/(3²)(π)
⇒ (h) = 45π/(9)(π) = 45/(9) = 5 units

Ava invests money in an account paying simple interest. She invests $130 and no money is added or removed from the investment. After one year, she has $132.60. What is the simple percent interest per year?
well, she put 130 bucks, and then she got back 132.6 after one year, so the interest earned is 132.6 - 130 = $2.6, thus
[tex]~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill & \$2.60\\ P=\textit{original amount deposited}\dotfill & \$130\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &1 \end{cases} \\\\\\ 2.60 = (130)(\frac{r}{100})(1)\implies 2.6=\cfrac{130r}{100}\implies 260=130r \\\\\\ \cfrac{260}{130}=r\implies 2=r[/tex]

The total cost of 8 sharpeners and 3 sketchbooks is $26.05. If the cost of a sharpener is $a, and a sketchbook is $1.90 more expensive,
find A. Give your answer to two decimal places.
Answer:
1.85
Step-by-step explanation:
So, s (sketchbook) is a+1.90.
8a+ 3(a+1.90)=26.05
8a+3a+5.7=26.05
11a=20.35
a=1.85
Check:
8x1.85=14.8
s=11.25
Answer:
A= 1.85
Step-by-step explanation:
I made an equasion
8(a) + 3(a+1.90) = 26.05
distributed
8a+ 3a + 5.70 = 26.05
Added
11a+ 5.70= 26.05
subtracted
11a= 20.35
divided
a= 1.85

Demarcus has to wrap a gift for his friend's birthday party. the gift is in a rectangular box with the dimensions shown below. he's trying to figure out how much gift wrap he needs to cover the entire box. should he calculate the total surface area or the lateral surface area? pick the right measurement and then calculate it for him. in your answer, specify whether he should use total surface area or lateral surface area. calculate the one you choose, give that measurement of the box, and then explain how you calculated it. grade 5 mathematics item specification c1 ti
The gift wrap needed by Damarcus = total surface area of a rectangular box = 1,048 in.².
What is the Total Surface Area of a Rectangular Box?Total surface area (TSA) = 2(wl+hl+hw), where:
l = lengthw = widthh = height of the box.The amount of gift wrap needed to cover the whole box = total surface area of the rectangular box
l = 20 in.
w = 8 in.
h = 13 in.
Plug in the values into the formula for total surface area of a rectangular box:
TSA = 2(8×20 + 13×20 + 13×8)
TSA = 1,048 in.²
Therefore, the gift wrap needed by Damarcus = total surface area of a rectangular box = 1,048 in.².

Find the surface area of the triangular prism shown below.
the surface area should be 544 (whatever the unit is)
Step-by-step explanation:
You start by taking the rectangles on the side and finding their area.
1. (10×14)×2 ←Because there are two rectanglular sides.
2. find the area of the triangles on the side. 1/2bh = area of triangle.
(.5×8×6)×4 ← in order to find the area for all of the triangles.
3. lastly take the base of the prism and find the area then add the previously found values together.
(12×14)+(.5×8×6)×4+ (10×14)×2 = 544

Answer:
m∠5 = 75°
Step-by-step explanation:
Angle 2 and Angle 4 are the same as they are alternate interior angles.
Since m∠2 = 45°
We then have m∠4 = 45°
We are given m∠3 = 60°
Now, we just have to find 7∠5.
The sum of the angle of a triangle adds up to 180°.
So, m∠3 + m∠4 + m∠5 = 180°.
60° + 45° + m∠5 = 180°.
Solving for ∠5
m∠5 = 180° - (60° + 45°)
m∠5 = 180° - (105°)
m∠5 = 75°

[tex] {6}^{x + 3} = \sqrt{6} [/tex]
Answer:
x=-5/2
Step-by-step explanation:
Hi there!
We are given the following equation:
[tex]6^{x+3} = \sqrt{6}[/tex]
We want to find the value of x
This is an exponential equation. In order to find the value of x, we need to make sure that both sides of the equation are at the same bases before we solve the equation
On the left side, we have 6 (the base) raised to the power of x+3
On the right, we have √6
Here's a trick to make this problem easier: the square root of a number is equal to that number, raised to the power of 1/2. In other words, √a is equal to [tex]a^\frac{1}{2}[/tex]
Therefore, √6 is equal to [tex]6^\frac{1}{2}[/tex]
Rewriting the equation then:
[tex]6^{x+3}=6^\frac{1}{2}[/tex]
Both sides have the same base (6)
Now we can solve the equation for x. Simply take what the exponents are, and then set them equal to each other.
This means:
x + 3 = 1/2
Subtract 3 from both sides
x+3=1/2

Six right triangles are shown. Each side of each triangle is also the side of a square.
The area of the small triangle in six right triangles are shown is 1/25 units² and the area of the small square is 1 units².
What is the area of square?Area of square is the square of its sides length. It can be given as,
A=a^2
Here, (a) is the length of the side of the square
The legs of the smallest triangle is 1-1 units long. Thus, the area of this triangle is,
[tex]A=\dfrac{1\times1}{2}\\A=\dfrac{1}{2}\rm\; unit^2[/tex]
The area of small squares with side 1 is,
[tex]A=1^2\\A=1 \rm \;unit^2[/tex]
Pythagoras theorem says that in a right angle triangle, the square of the hypotenuse side is equal to the sum of the square of other two legs of the right angle triangle.
The hypotenuse side length of this triangle is,
[tex]h=\sqrt{1^2+1^2}\\h=\sqrt{2}[/tex]
Thus, the area of the square with √2 side is,
[tex]A=\sqrt{2}^2\\A=2\rm\; unit^2[/tex]
Similarly, the area of all the squares and triangle with the different sides can be found out.
Thus, the area of the small triangle in six right triangles are shown is 1/25 units² and the area of the small square is 1 units².
