Answer:
678.672cm^2
Step-by-step explanation:
Given data
A cone is described by the length and radius
l=19cm
r=8cm
The formula for the surface area of the cone is
T.S.A=πrl+πr^2
Substitute
T.S.A=3.142*8*19+3.142*8^2
T.S.A=477.584+201.088
T.S.A=678.672
Hence the surface area is
678.672cm^2

area = (14 x 16) - (0.5 x 16 x 6) = 176 ft²
Step-by-step explanation:
Answer:
A = 176 ft²
Step-by-step explanation:
2 shapes: one rectangle and 1 triangle:
Rectangle:
A = bh
A = 16(14)
A = 224
Triangle:
A = 1/2bh
A = 1/2(16)(6)
A = 48
Combined:
224 - 48
176

Answer:
48°
Step-by-step explanation:
We solve the above question using circle theorem.
Finding x
The formula is given as
x = 1/2 (150° - 54°)
x = 1/2 (96)°
x = 48°
the area of a rhombus is 24 square inches. What is the are of a similar rhombus that is 7 times as big?
Answer: 1176
Step-by-step explanation: 7 times as big is an ambiguous term; it could mean that each side is 7 times larger, or that the shape as a whole is made 7 times larger. We'll assume that each side is made larger, because that is typically the type of question asked. The area is given as base times height, and obviously, if you dilate the non-base side by 7, the height will also become 7, because those two lines from a triangle with the third side being the base extended. I wish I could draw you a diagram but i can;t. Either way, think of it as a square, and if we dilate each side by 7, then we have lx7xwx7=Area, which is lw*49=49 times the given area, which is 24; 24*49=1176

Find the area of the shaded region.
A. 5x2 – 11x + 16
B. 5x2 + 7x – 26
C. 5x2 + 11x – 12
D. 5x2 + 7x – 20
Area of the shaded region = area of big square minus area of little square.
Here is the set up:
Let A_s = area of shaded region.
A_s = (2x + 2)(3x - 4) - [(x - 3)(x - 6)]
Take it from here.
Answer:
B. 5x2 + 7x – 26
Step-by-step explanation: keeping in mind that the area of a rectangle is simply width * length, if we get the area of the larger rectangle, and then subtract the area of the smaller rectangle, we're in effect making a hole in the larger rectangle's area and thus what's leftover is the shaded area.
.................................................................................................................................
Answer:
Area = 5x^2 +7x -26
Step-by-step explanation:
The area of the shaded region can be found if you substruct the small rectangle from the big one. The area of any rectangle is calculated if you multiply width and height.
In other words:
A_small = (x-3)(x-6) = x^2-9x +18
A_big = (2x+2)(3x-4) = 6x^2 -2x -8
A_big - A_small = (6x^2 -2x -8) - (x^2-9x +18)
= 6x^2 -2x -8 - x^2 + 9x -18
= 5x^2 +7x -26
x/2 + 4 < 18

Worth 29 points
Answer:
x<28
Step-by-step explanation:
Isolate x
First, subtract 4 on both sides
x/2+<14
Then, multiply both sides by 2 to get x alone
x<28
On a number line, there would be an open circle (not filled in dot) on 28, and the entire left side of the number line would be filled in
Answer:
x<28
Step-by-step explanation:
x/2+4<18
multiply the 2 on both sides to get rid of it
x+8<36
isolate the x
x<28
on the number line, it's an open circle with the arrow pointing to the left.

Find the measure of each number:
Step-by-step explanation:
11. angles 1 and 2 are vertical angles, meaning they are congruent.
angle 2=angle 1=38 degrees
14. angles 1 and 2 are supplementary angles, meaning they add to 180 degrees.
angle 1=180-angle 2=180-67=113 degrees

B. 29
C. 46
D. 134
Answer:
A
Step-by-step explanation:
Remarks
The given angle is an exterior angle.It's value is 46 degrees. An exterior angle is the sum of the two remote angles. (A remote angle is one that is not supplementary to the given exterior angle.Solution
46 = <u + <t<t = 2946 = <u + 29 Subtract 29 from both sides.46 - 29 = <u<u = 17 degrees1. Determine the value of y for y = x -2

The highest value on the domain of the function is called its ____ ____. (2 words)
starts with ab
Answer:
It is called the maximum value.
Step-by-step explanation:
The highest value on the domain of the function is called its maximum value.
What is domain and range of the function?The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:
Domain = the set of all x-coordinates = {1, 2, 3, 4}
Range = the set of all y-coordinates = {2, 3}
The maximum value of a function is the place where a function reaches its highest point, or vertex, on a graph. There is no point above the maximum value of the function. Thus the highest point on the graph is known as the maximum value of the domain of the function.
The maximum value is one of the extreme values of the domain of the function. The other extreme value is known as the minimum value. It is on one side of the graph and the maximum value is on the other side of the graph.
Therefore, the highest value on the domain of the function is called its maximum value.

Rachel has 42 stickers she wants give to her friends. Rachel put the stickers in 7 equal groups. Then Rachel found more stickers and put 3 more in each pile. If Rachel gives 5 stickers to each of her 12 friends, how many stickers does she have left over?
Answer:
3 stamps
Step-by-step explanation: 42 stamps in equal groups would be 6 stickers/group.
6+3 = 9 stickers in each pile
there was 7 piles so multiply 7 by the 9 stickers in each pile
7· 9 = 63
5 · 12 = 60, so she gave her friends 60 stickers
63-60 = 3
