Find the area of the figure
Answer:
145.1327
Step-by-step explanation:
Divide the given figure up into two smaller figures. Calculate the area of each of the smaller figures and then add up the areas. One can divide this figure into a rectangle with sides (8 and 15), and a semi-circle with a diameter of (8m).
Calculate the area of the rectangle, the formula to calculate the area of a rectangle is ([tex]base*height[/tex])
8 * 15 = 120
Calculate the area of the semi-circle. The formulas for the area of a semi-circle is the formula for the area of a circle divided by (2), ([tex]A=\frac{(pi)r^2}{2}[/tex]). Where (A) represents the are, (pi) represents the number (3.1415...), and (r) represents the radius of the circle. The radius is always half of the diameter of a cricle. Substitute in the given values, and solve
[tex]\frac{(pi)(\frac{8}{2})^2}{2}[/tex]
[tex]=\frac{(pi)(4)^2}{2}[/tex]
[tex]=\frac{(pi)16}{2}[/tex]
[tex]=8(pi)[/tex]
~25.1327
Now add up the two values,
120 + 25.1327
= 145.1327

Step-by-step explanation:
Sammy draws 3 identical rectangles on his paper. If each rectangle has a base of 15 cm and a height of 12 cm, what is the total area of all 3 rectangles added together?
Answer:
540
Step-by-step explanation:
If you do 15x12 which is the formula for area for a rectangle, you get 180. That's only the area of one rectangle but if you multiply it by 3 you get 540 for the areas added together.
Answer:
540 cm
Step-by-step explanation:
you multiply 15 x12 If you are getting an area 15 x12=180 then you multiply 180 by 3 180x3=540 I think

Answer:
This is the famous "Ice cream cone" problem. notice that if you turn the object 90° counter clock wise , it looks like an ice cream cone. anyway
Step-by-step explanation:
the two triangles on the pointy end make a box , if you put them together, so it's a box of 4 x 11 or 44 [tex]in^{2}[/tex].
then the actual box part in the middle it's 3 x 8 or 24 [tex]in^{2}[/tex].
and finaly the ice cream :P or the round part. well half round part.
it's half of a circle..(we don't really know if the arc is really a circle from the problem but I'm guessing that we are supposed to assume that it is ) and the area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]
then [tex]\pi[/tex]*[tex]4^{2}[/tex] = 50.2655 which is the entire circle but we only have half.. so divide by 2 = 25.1327 [tex]in^{2}[/tex].
add the 3 parts
93.1327 [tex]in^{2}[/tex].
that's the total area of the "ice cream cone"

Its says in question 4 tue horizontal translation is A right.?
Answer:
Here we have:
g(x) = 3*f( 2*x - 2) - 1
We want to know the horizontal translation used here.
We need to discuss two types of transformations here.
horizontal translation.
If we have a function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N)
if N is negative, the translation is to the right.
if N is positive, the translation is to the left.
Horizontal dilation.
For a function f(x) an horizontal dilation of scale factor k is written as:
g(x) = f( x/k)
You can see that in our function we have both of these transformations.
Because we compare the translation with f(x), we assume that the horizontal translation is the first thing we did, then we must have
translation:
g(x) = f(x + N)
and now a horizontal dilation of scale factor k
g(x) = f( (x + N)/k)
Then we must have that the argument of the above function is the same as the argument of the given function.
(x + N)/k = 2*x - 2
then:
k = 1/2
(x + N)/1/2 = 2*x + 2*N = 2*x - 2
2*N = -2
N = -2/2 = -1
This means that we have a translation of 1 unit to the right.

What is the area of this parallelogram?
104 m²
88 m²
56 m²
32 m²
Answer: To find area of a rectangle, multiply its base (length) by its height (width). Plug in the base, 7 meters, and the height, 8 meters. So the area of Rectangle DFBE is 56 square meters.
88m

the length and the breadth of a rectangular Garden are 0.8 km and 0.6 km respectively find the length of a wire required to put a fivefold fans around the garden
Answer:
Length of wire required for 5 fold of garden = 14 km
Step-by-step explanation:
Given:
Length of rectangle garden = 0.8 km
Width of rectangle garden = 0.6 km
Find:
Length of wire required for 5 fold of garden
Computation:
Perimeter of rectangle = 2[l + b]
Perimeter of garden = 2[0.8 + 0.6]
Perimeter of garden = 2[1.4]
Perimeter of garden = 2.8 km
Length of wire required for 5 fold of garden = 5 x Perimeter of garden
Length of wire required for 5 fold of garden = 5 x 2.8
Length of wire required for 5 fold of garden = 14 km
perimeter 254 meters and dimension measures 6 meters

Answer:
384 cm²
Step-by-step explanation:
Since it is a square pyramid, the total surface area of the pyramid is the area of its square base plus the area of its 4 triangular faces.
[tex]\boxed{area \: of \: triangle = \frac{1}{2} \times base \times height }[/tex]
Area of a triangular face
= ½ ×12 ×10
= 60 cm²
[tex]\boxed{area \: of \: square = side \times side}[/tex]
Base area of pyramid
= 12 ×12
= 144 cm²
∴ Surface area of pyramid
= 4(60) +144
= 240 +144
= 384 cm²

a set of speakers that regularly cost $160 are on clearance for 35% off. Find the sales price of the speakers
Answer:
I'm pretty sure this is the answer....
The speakers are $56.
Sorry if i'm wrong. :')
Step-by-step explanation:
Answer:
You want to buy something that costs $160, and it's on sale for 35% off. What is the item's sale price?
First, convert the 35% to a real mathematical number. For percents, this is always done by dividing the 35% by 100%, or 35% / 100% = 0.350.
Second, find out what 35% of $160 is. This is the amount of the sale discount. This is always found by mulitplying 0.350 by the item's cost $160, like this:
0.350 x $160 = $56.00.
So for this sale, you'll save $56.00 on this item.
This means, the cost of the item to you is
$160 - $56.00 = $104.00.
Alternatively, you can think about it this way. The item is 35% off. This means you'll pay 65.000% of the total cost (100% - 35% = 65.000%).
Now what's 65.000% of the total cost?
0.650 x $160 = $104.00.
Just like the result above, the sale price on the item is $104.00
What is the equation of the following line?
Answer:
E
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
slope = rise / run = 7 / 1 = 7
m = 7
y-intercept = 0
So:
y = 7x + 0
y = 7x
