Two angles are supplementary angles if the sum of their measures is 180 degrees. Find the measures of two supplementary angles if the measure of one angle is 3 degrees less than twice the other.
Answer:
60 degrees and 119 degrees
if the smaller angle is x, then
x + 2x - 3 = 180
3x -3 + 3 = 180 + 3
3x/3 = 183/3
x=61
2(61) - 3 = 119

The pictures to the right show how much sausage and pepperoni pizza was left at the end of one day. Which fraction represents how much more sausage pizza then pepperoni pizza was left?
Answer:
3/8
Step-by-step explanation:
There was 4/8 (or 1/2) of the pepperoni pizza left, and there was 7/8 of the sausage pizza left. To find out how much more sausage pizza was left than pepperoni pizza, you have to subtract the amount of pepperoni pizza remaining from the amount of sausage pizza remaining.
sausage pizza left - pepperoni pizza left = how much more sausage pizza than pepperoni pizza is left
Now, let's fill in the numbers.
7/8 - 4/8 = ?
7/8 - 4/8 = 3/8
Therefore, there was 3/8 more sausage pizza than pepperoni pizza left.
I hope this helps! Have a lovely day!! :)
Answer:
3/8
Step-by-step explanation:
So there is 7/8 sausage left and 4/8 pep left. The difference between the two is three slices (7/8 - 4/8) which is 3/8th of the whole pizza. This means that 3/8 represents the amount of pizza sausage has that pepperoni doesnt

Ray YL bisects ZAY B. Find the measurement of
ZBYL.
B
(7x + 17)
(3(4x - 1))
Y
0 90
0 45
0 None of the above
0 20
Answer:
B. 45
Step-by-step explanation:
YL is the angle bisector of ∠AYB, so the two angles are congruent:
∠AYL ≅ ∠BYLSubstitute and solve for x:
7x + 17 = 3(4x - 1)7x + 17 = 12x - 312x - 7x = 17 + 35x = 20x = 4Find the value of ∠BYL:
3(4*4 - 1) = 3(16- 1) = 3(15) = 45
This is matching the answer option B.
The red angles must be equal as YL is bisector
7x+17=3(4x-1)7x+17=12x-317+3=12x-7x20=5xx=4<BYL
3(4(4)-1)3(16-1)3(15)45Option B

Write an equation and solve it. Anything goes as long as you address the following points:
a. The equation must start with an 'x' variable in an exponent.
b. The equation must require logarithms to solve.
c. In the solution you must use the power rule, the product rule and the quotient rule at least once each.
d. Explain each step as you solve; which rules are you using and why?
e. What challenges did you face as you were writing your problem? Did you run into any dead ends?
My problem lies in finding an exponential equation [tex]N^x=N^x[/tex] (N being any positive number) that needs all 3 rules to solve. I can come up with an equation that uses 2 of the rules but I'm stuck on adding the third. Any suggestions would be nice. Thanks

What is the next number in the sequence? 9….16….24….33…
Answer:
43
Step-by-step explanation:
The first increase from 9 to 16 is 7
The second increase from 16 to 24 is 8
The third from 24 to 33 is 9
Following the pattern the next increase must be by 10. 33+10=43
Find the set of values of m for which the line with equation y = mx + 1 and the curve with equation y = 3x^2+ 2x + 4 intersect at two distinct points.
Answer:
Given : line y=mx+4 intersects the curve y=3x2 −4x+7at two distinct points.
To find : set of values of m
Step-by-step explanation:
y = mx + 4
y = 3x² − 4x + 7
Substitute y = mx + 4 to find intersection point
mx + 4 = 3x² − 4x + 7
=> 3x² - x(m + 4) + 3 = 0
(m + 4)² > 4(3)(3)
=> m² + 8m + 16 > 36
=> m² + 8m - 20 > 0
=> (m + 10)(m - 2) > 0
m < - 10 & m > 2
m = (-∞ , - 10) ∪ ( 2 , ∞ )
Making auto parts A grinding machine in an auto
parts plant prepares axles with a target diameter
p = 40.125 millimeters (mm). The machine has
some variability, so the standard cleviation of tlic
diameters is a = 0.002 mm. The machine operator
inspects a random sample of 4 uxles cach hour for
quality control purposcs and records llic sample
mcan diameter 1. Assuming that the process is work-
ing properly, what are the mean and standard devia I
fion of the sampling distribution of ? Explain.
Answer: See below
Step-by-step explanation:
Mean:
Since the sample is taken from a large population it follows the central limit theorem, which states that the sample mean is approximately equal to the population mean.
Therefore: [tex]\bold{\bar{X}=\mu=40.125}[/tex]
Standard Deviation:
Again by central limit theorem the standard deviation of the sample is calculated as:
[tex]S=\frac{\sigma}{\sqrt{n}}[/tex]
Since n=4, therefore
S = 0.001

3d + d what do i put this is Confusing
Answer:
4d
Step-by-step explanation:
i think any variable alone with no coefficient equals one
so this problem is like adding the terms 3d + 1d
so 1+3=4
and you use the variable d at the end
therefore the answer would be 4d
hope this helped<3
Answer:
4d
Step-by-step explanation:
3d+d this means 3d+1d because any variable without a coefficient is 1
which means
3d+1d
=4d

if a sum of money increased by 1/5 of itself every year and in 5 years amounts to Rs.8546,find the sum
Answer:
Answer :
Given : If a sum of money amounts to Rs 2200 in 5 years
Let sum of money = x
And as given : The interest is 3838 of the principal . So we get
x ( 3838 ) = 2200 - x
3x = 17600 - 8x
11x = 17600
x = 1600
So, Sum of money = Rs . 1600
Then interest = 2200 - 1600 = Rs . 600
Let Rate of interest = r %
And we know Simple interest = P × r × t100P × r × t100 , So we get
⇒1600 × r × 5100 = 600⇒16× r × 5100 = 6⇒80r = 600⇒r = 60080 = 152 = 712%⇒1600 × r × 5100 = 600⇒16× r × 5100 = 6⇒80r = 600⇒r = 60080 = 152 = 712%
