Answer:
area: 1070
perimeter: 434 units
Step-by-step explanation:
area:
- use pythagoream theorem to find the height, which is gonna be 84
- from there, you're gonna wanna find the area of the rectangle and then the two triangles. the way i do it is by just finding the area of the rectangle first, 100x84 = 8400, and then finding the area of the triangles (35x84/2 = 1470 and 20x84/2 = 840)
- you have the area of all shapes, now just add them together (8400+1470+840 = 10710)
perimeter:
just add all the lengths given together.
KL, LM, MN and KN are tangent to the circle. what is the perimeter of KLMN
Answer:
perimeter = 46
Step-by-step explanation:
Segments of tangents to a circle from the same external point are congruent.
KL = 3 + 4 = 7
LM = 4 + 10 = 14
MN = 10 + 6 = 16
NK = 6 + 3 = 9
Perimeter = 7 + 14 + 16 + 9 = 46
Given the triangle below, list its angles in order from smallest to largest.
Answer:
<J, <k, <L
Step-by-step explanation:
Automatically we know that L is the largest because it is a right triangle making it 90 degrees. Next we know J is the smallest because looking at the opposite side the 13 is the shortest side making that the smallest angle putting K in the middle.
A number is less than one-fourth the sum of eight times the number and four.
Answer:
Assume the number is X. What is given can be written as the following:
X < (1/4)*(8X+4)
Multiply 4 on both sides
4X< 8X+4
Subtract 4X+4 from both sides
-4 < 4X
-1<X i.e., X>-1 the number is greater than -1.
Vertical lines have _________ slope.

Jacob is a plumber. Due to increased material costs, he puts all his prices up by 7%. He now chargers R320 per hour for her services. What did he charge before he put his prices up?
Answer:
R290.1
Step-by-step explanation:
Let
x = charge before he put his prices up
New charge = R320
Percentage increase in price = 7%
x + 7% of x = 320
x + 0.07 * x = 320
x + 0.07x = 320
1.07x = 320
x = 320/1.07
x = 299.06542056074
Approximately
x = R290.1
Charge before he put his prices up = R290.1

The length of the base of an isosceles triangle is x. The length of a leg is 2x - 2. The perimeter of the triangle is 51. Find x.
Answer:
x = 11
Step-by-step explanation:
x + 2(2x-2) = 51
x + 4x - 4 = 51
5x - 4 = 51
5x = 55
x = 11
Answer:
x = 11
Step-by-step explanation:
2x - 2 + 2x - 2 + x = 51
5x - 4 = 51
5x = 55
x = 11
Can someone help me on this plzzz
Answer:
b=15
How I got it:
32 + (7x4) = 32 + 28 = 60
60 divided by 4 = 15
Checking:
15 - 7 = 8
8 x 4 = 32
32 = 32
You can tell b = 15 is the correct answer.

What is the volume of this cone
Answer:
4096pi/3
Step-by-step explanation:
Volume is pi * r^2 * h/ 3
r (radius) = 16
h (height)= 16
pi * 256 * 16/3 = 4096pi/3
i can’t figure out the answer
Answer:
Pythagoras theorem
hypotenuse²=base²+height²
(24)²=base²+(9)²
576=base²+81
576-81=base²
494=base²
[tex] \sqrt{494} = base \\ 22.24 = base[/tex]

Ms. Nelson has 8 pounds of ground beef. She is making burgers that are ¼ pound each.
Answer:
she will make 32 burger patties.
One way:
8 x 4 = 32
the fraction will get reversed so it turns to 4.
Second way(basically the same as the first way):
8 divided by 1/4 = 8 x 4= 32
You just have to divide 8 by 1/4. The fraction gets reversed in divisions so it turns to 4.
Answer:
ok the answer is...
Step-by-step explanation:
32!!
the reason for this is because 1/4 + 1/4 + 1/4 + 1/4 = 4!
so do that again all over again 8 times and you have your answer.

Using rational roots theorem, we can see that the possible roots of the the given equation are:
By substituting the possible roots, we can see that x = 1 is a root, thus x - 1 is a factor.
We can get the other factors by using sythetic division to divide by x - 1.
Step-by-step explanation:
x^3+x^2+4x+4=0
x³+x²+4x=-4
x(x²+x+4)=-4
either
x=-4
or
x²+x+4=-4
x²+x+4+4=0
