Answer:
20
Step-by-step explanation:
We know that a triangle's angles must add up to 180 which means that
100+40+2x=180
solve for x
140+2x=180
2x=40
x=20

A. 48
B. 124.8
C. 135.2
D. 115.2
Answer:
B. 124.8Step-by-step explanation:
ΔBDS ~ ΔBZD
BD = 52BZ = 20BS = ?Use ratios of similar triangles:
BS/BD = DZ/BZBS = BD*DZ/BZDZ = √(52²-20²) = 48
BS = 52*48/20 = 124.8Correct choice is B
The radius of a circle is 10 meters. What is the area of a sector bounded by a 45° arc?
45°
r=10 m
Give the exact answer in simplest form.
Answer:
The area of the circular sector is approximately 39.269 square meters.
Step-by-step explanation:
A circular sector is a segment of a circle, whose area ([tex]A[/tex]), measured in square meters, is determined by this formula:
[tex]A = \frac{\theta}{2} \cdot r^{2}[/tex] (1)
Where:
[tex]\theta[/tex] - Central angle, measured in radians.
[tex]r[/tex] - Radius, measured in meters.
If we know that [tex]\theta = \frac{\pi}{4}[/tex] and [tex]r = 10\,m[/tex], then the area of the circular sector is:
[tex]A = \frac{\pi}{8} \cdot (10\,m)^{2}[/tex]
[tex]A \approx 39.269\,m^{2}[/tex]
The area of the circular sector is approximately 39.269 square meters.
Answer:
39.269

Please help! (Geometry)
Answer:
x=5
From the dashed lines on the two sides of this triangle, we can see that these two sides are congruent, or equal, to each other.
In geometry, if a triangle has two congruent sides, then we can call it a isosceles triangle.
In an isosceles triangle, the corners opposite the congruent sides are also congruent, meaning, that the angle measures of this triangle are: 88, 9x+1, and 9x+1.
We also know that angles in a triangle add up to 180 degrees.
So, we have: 88+(9x+1)+(9x+1) = 180
Simplifying: 18x + 2 = 92
Solving: 18x = 90, so x=5

Wendell didn't make it in Nashville. Now he only
has $12 in nickels and dimes left to his name-
barely enough to pay for a bus ticket back
home. If Wendell has 3 times as many nickels
as dimes, how many dimes does he have?
Help meee lol
Answer:
Wendell only has $12 in nickels and dimes
Let Wendell have x dimes
If Wendell has 3 times as many nickels as dimes, how many dimes does he have?
Number of nickels = 3x
dime 10 c
nickel 5c
10x+5*3x = 1200 ( $12=1200 c)
25x = 1200
x= 48 number of dimes
9+x=-11

The sum of two numbers is 44 and the difference is 2 What are the numbers
Answer:
21 & 23
Step-by-step explanation:
44 ÷ 2 = 22
The two numbers are going to be close to 22.
21 + 23 = 44
32 - 21 = 2
Answer:
You can try to write two equation from the question
Call x a number and y the other.
The sum of them is 44: x + y = 44
The difference (substract) is 2: x - y = 2
System:
x+y=44
x-y = 2
You can just sum both equations, as the y disappear:
2x = 46
x =46/ 2 = 23
We replace in the equation:
23 - y = 2
y = 21
And we know the numbers are 21 and 23
88 is a solution to (1/8) x =11 because if x = 88 then the equation (1/8) x = 11 is true.
Answer:
True
Step-by-step explanation:
To check to see if the statement given is true we need to substitute x with 88 and solve.
[tex](1/8)x=11[/tex]
Substitute 'x' for 88.
[tex](1/8)88=11\\\\\boxed{11=11}[/tex]
88 is a solution to the equation, therefore the statement is true.
Hope this helps.

2/5+____= 11/15
Answer:
1/3 is the answer
Step-by-step explanation:
Answer:
hi! so first you make 2/5 into 6/15 and the answer would be 5/15 (or 1/3 if you simplify it) because 6/15+5/15=11/15

Factor the expression using 3 as one factor. 3x−30
Answer:
3(x - 10)
Step-by-step explanation:
3x - 30 = 3(x - 10)
Hii!
__________________________________________________________
Answer:
3(x-10)
Step-by-step explanation:
Note that both terms, 3x and -30, have a 3 in common. This is called the greatest common factor, or g.c.f.
The g.c.f. of 3x and -30 is 3. So we divide both 3x and -30 by 3, and obtain
x-10
Put parentheses around x-10
(x-10)
Next, put 3 outside the parentheses
3(x-10)

Today, Reza ate 20 grapes, which was 400% as many
grapes as he ate yesterday. Explain how to use
equivalent ratios to find the number of grapes Reza ate
yesterday. (help plz)
its not a sin to want to win cant see meflying like a bee i see a dreamer other there by the water but i
LOL
Answer:
What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.
To do it, let:
x: number of grapes that Reza ate yesterday
(x / 20) = (100/400).
Clearing x we have:
x = (100/400) * (20) = 5
answer
the number of grapes Reza ate yesterday was 5

Answer:
..Step-by-step explanation:
9x - 4y= 19
4x + 4y= 20
Answer:
x=3 and y=2
Step-by-step explanation:
9x - 4y= 19
4x + 4y= 20
add both equations;
13x = 39
x= 3
using 4x + 4y= 20;
4(3) +4y=20
12+4y=20
4y= 20-12=8
y=8/4=2

Answer:
y = -2
Step-by-step explanation:
3(3v-5) = 39
Simplify your answer as much as possible.
Answer:
v = 6
Step-by-step explanation:
Given
3(3v-5) = 39
So,
3v - 5 = 39 / 3
=> 3v - 5 = 13
=> 3v = 13 + 5
=> 3v = 18
=> v = 18 / 3
=> v = 6
#HopeItHelps
Answer:
V=6
Step-by-step explanation:
Hope this helped! :)
Simplifying
3(3v + -5) = 39
Reorder the terms:
3(-5 + 3v) = 39
(-5 * 3 + 3v * 3) = 39
(-15 + 9v) = 39
Solving
-15 + 9v = 39
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 9v = 39 + 15
Combine like terms: -15 + 15 = 0
0 + 9v = 39 + 15
9v = 39 + 15
Combine like terms: 39 + 15 = 54
9v = 54
Divide each side by '9'.
v = 6
Simplifying
v = 6

5,6,7,and 8 plz
Answer:
number 5:4/12
#6: 25/45
#7: 26/44
#8: 52/30
Step-by-step explanation:
Answer:
5) 1/3=x/12
12=3x
3x=12 (divide both sides)
12 divided by 3 = 4
therefore, x = 4
6) 5/9=25/y (cross multiply the numbers)
after cross multiplying you should get: 5y=225
divide both sides to get 45
therefore, y = 45
7) 26/z = 13/22 (cross multiply numbers)
after cross multiplying, you should get: 572=13z (swap the numbers)
after swapping the number, you should get: 13z=572 (divide both sides)
after dividing you should get 44
therefore, z = 44
8) b/30 = 2.6/1.5 (simplify expression)
after simplifying you should get: b/30=26/15 (cross multiply after)
after cross multiplying you should get: 15b = 780 (divide both sides)
after dividing both sides, you should get: 52
therefore, b = 52
Hope this helps:)!
