HELP!!! Will mark brainliest!!
Step-by-step explanation:
BDC and ACD are complementary with each other. that means together they cover the full 180 degrees of the half circle that can be drawn on one side of a flat line.
180 = 11x + 25 + 4x + 5 = 15x + 30
150 = 15x
x = 10
BDC = 11x + 25 = 11×10 + 25 = 110 + 25 = 135 degrees
ACD = 4x + 5 = 4×10 + 5 = 40 + 5 = 45 degrees
if x and y are two overlapping subsets of a universal set U, write the relation between n(U),n(X U Y), and n(xūy).

Answer:
a. 1
b. 3
c. 9
Step-by-step explanation:
all you have to do is plug in 2 to the equations as x and solve for y!
a.
y = 7 - 3(2)
y = 7 - 6
y = 1
b.
y = (2)^2 -1
y = 4 -1
y = 3
c.
y = (18/(2))
y = 9

Step-by-step explanation:
to rent a popcorn machine, it costs 35$ plus $6.95 for each hour. write and evaluate an expression to find the total cost of renting the popcorn machine for 5 hours. then make a table showing the cost for 5, 6, 7, and 8 hours
Answer:
y=6,95x+35
Step-by-step explanation:
y=6,95x+35
y=6,95*5+35=69,75 for 5 hours
for 6 hours y=76,7
for 7 hours y=83.65
for 8 hours y=90,6

-4+4(-8+2n) = -37+8n
Answer:
No solutions for n
Step-by-step explanation:
Distribute the 4 to the -8 and the 2n
-4 + 4*-8 + 4*2n = -37 + 8n
Multiply
-4 - 32 + 8n = -37 + 8n
Subtract 8n on both sides
-4 - 32 = -37
Subtract on the left
-36 = -37
No solutions because -36 does not equal -37
Answer:
No solution
Step-by-step explanation:
-4 + 4(-8 + 2n) = -37 + 8n
-4 - 32 + 8n = -37 + 8n
-36 + 8n = -37 + 8n
8n - 8n = -37 + 36
0 = -1
Since 0 does not equal 1, this is a “No Solution”
Find the distance between the pair of points. (5,25) and (−19,−12) The distance is nothing. (Round to the nearest thousandth as needed
Answer:
44.1
Step-by-step explanation:
- To find the distance, we have to use the distance formula:
d = √(x2 - x1)² + (y2 - y1)²
d = √(-19 - 5)² + (-12 - 25)²
d = √(-24)² + (-37)²
d = √(576) + (1369)
d = √1945
d = 44.1

Find the 11th term of the geometric sequence 10,20,40
Answer:
10, 20, 40
scale factor = x2
10, 20, 40, 80, 160, 320, 640, 1280, 2560, 5120, 10240
answer = 10,240
Answer:
10,240
Step-by-step explanation:
First, we find the constant ratio by dividing a number by the previous number.
r = 40/20 = 2
Now we apply the formula for term a_n of a geometric sequence.
a_n = a_1 * r^(n - 1)
a_11 = 10 * 2^(11 - 1)
a_11 = 10 * 2^10
a_11 = 10,240
IF ONE THIRD OF THE SCHOOL STUDENTS LIKE MATHEMATICS AND 400 STUDENTS DO NOT LIKE MATHEMATICS , THEN HOW MANY STUDENTS DOES THE SCHOOL HAVE ?
A. 600 B. 800
C. 200 D. 1000
Answer:
There are 600 students in this school.
Step-by-step explanation:
Let p represent the total population of the school.
Then (1/3)p represents the number of students who like math. Subtracting this (1/3)p from p gives an expression representing those who do not like math:
p - (1/3)p = (2/3)p
400 students do not like math, so (2/3)p = 400.
Solve this for p by multiplying both sides by (3/2):
(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.
There are 600 students in this school.
plz just solve the questions 3 and 4 only thank you brainiest will be given out to the correct answer
Answer:
3. the proportional relationship is that for every cup of blue paint, you need 5 cups of yellow paint. so the relationship between the yellow and blue paint that keeps it proportional is 5 time the cups of blue paint, is how many cups of yellow paint you need
4. constant of proportionality is 5 because for every cup of blue paint, you need 5 cups of yellow paint:
2 * 5 = 10
1 * 5 = 10
3 * 5 = 10

A number line shows 1 1/5, −2 2/5, and −1 3/5. Which statement is NOT true?
Answer:
The answer Is A 1 1/5 < -2 2/5
Step-by-step explanation:
It says that this statement is true because 1 1/5 is to the left of -2 2/5 on the number line but it is actually to the right because -2 2/5 is negative while 1 1/5 is positive therefore making it larger and the correct statement would be that 1 1/5 > -2 2/5
Write and equation of the line that passes through the point (2,-6) and is parallel to the line x-2y=8
Answer:
y=0.5x-7
Step-by-step explanation:
x-2y=8
2y=x-8
y=0.5x-4 m1=0.5
m1=m2=0.5 - the slope for parallel lines are equaly
y=m2x+b
-6=0.5*2+b
b=-7

Hint:
[tex](a^{m})^{n}=a^{m*n}[/tex]
Answer:
[tex]1/x[/tex]
Step-by-step explanation:
To simplify, work from the inside out.
We start with
[tex]\sqrt[4]{x^{3/4}}[/tex]
on the inside. And we can change the fourth root into a fractional exponent -- 1/4:
[tex](x^{\frac{3}{4})^{1/4}[/tex]
A power of a power means multiply the exponents, giving
[tex]x^{\frac{3}{4} * \frac{1}{4}} = x^{3/16}[/tex]
So now we have
[tex][(x^{3/16})^{-4/3}]^4[/tex]
From here, apply the "power of a power rule" again, working from the inside out.
[tex](x^{-12/48})^4[/tex]
[tex]x^{-48/48}[/tex]
[tex]x^{-1}[/tex]
