Answer:
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees.
a+b=180
We are told that b=a+62 so
a+a+62=180
2a+62=180
2a=118
a=59, and since b=a+62,
b=59+62
b=121 so the angles are 59 and 121

. Attendance at the drama play was 140% of attendance at the concert. How many people came to the drama play?
This question is incomplete
Complete Question
A school held several evening activities last month—a music concert, a basketball game, a drama play, and literacy night. The music concert was attended by 250 people. How many people came to each of the other activities?
Attendance at the drama play was 140% of attendance at the concert. How many people came to the drama play?
Answer:
350 people
Step-by-step explanation:
Percentage of people that attended a drama play =
Number of people that attended the drama play/Total number of people at the concert × 100
Attendance at the drama play was 140% of attendance at the concert.
The music concert was attended by 250 people
Let the number of people that came to the drama play = x
Hence:
140% = x/250 × 100
140/100 = x/250
Cross Multiply
140 × 250 = 100 × x
x = 140 × 250/100
x = 350 people
Therefore, the number of people that came to the drama play = 350 people
The table shows data for a car stopping on a wet road. Stopping distance formula [tex]d(v)=\frac{2.15v^{2} }{64.4f}[/tex]
Determine the value of f, rounded to the nearest hundredth.
Answer:
0.35
the next one is d(v) = 2.15v^2 / 22.54
Step-by-step explanation:
i just did this assignment. also thanks to the answer above me :)
We have that the value of f, rounded to the nearest hundredth.
f_1=0.02
f_2=0.009
f_3=0.009
From the question we are told that
d(v)= \frac{2.15v^2}{64.4f}
Generally the equation for the f is mathematically given as
f= \frac{2.15v^2}{64.4*d(v)}
Therefore
For v=20 and f=38
f= \frac{2.15(20)^2}{64.4*(38)(20)}
f=0.02
For v=30 and f=86
f=\frac{2.15(30)^2}{64.4*(86)(30)}
f=0.01
For v=40 and f=153
f=\frac{2.15(40)^2}{64.4*(153)(40)}
f=0.009

pls help trigonometry is confusing to me :(
My first tip would be to label your triangles.
If you find our reference angle and go across, that would be our opposite side, so x is the opposite side.
The line with both the reference angle and the right angle would be our adjacent side, so 40 would be the adjecent side.
If you find the right angle and go across, that would be our hypotenuse.
//
In this problem, we are given an angle and the adjacent side and we are looking for the opposite side, so that means that we would be using our tangent ratio.
[tex]tan = \frac{opp}{adj} = \frac{x}{40} [/tex]
[tex] \tan(43) = \frac{x}{40} [/tex]
if the thing you are looking for is on the numerator, we would have to multiply. If the thing you're looking for is in the denominator, you would have to divide.
Since x is on the numerator, we would have to multiply.
[tex]x = 40 \tan(43 ) [/tex]
[tex]x = 37.3006034455[/tex]
[tex]x = 37.30[/tex]
You earn $320 in 40 hours. At this rate how many hours do you work to earn $440?
Answer:
60.5
Step-by-step explanation:
320/44=7.27
440/7.27=60.5
Answer: 55 Hours
Step-by-step explanation:
If you take 320 and divide it by 40
you get 8
This means you earn $8 for every hour you work.
Now if you take 440 and divide it by 8, meaning $440 dollars divided by $8
You will get
55, meaning you must work 55 Hours to make $440.

PLZZZ HELP!!! WILL MARK BRAINLIEST! Maggie wants to know if the number of words on a page in her science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Mean Median Mean Absolute Deviation
Science 49.7 41 8.4
Math 34.5 44 1.9
She claims that because the mean number of words on each page in the science book is greater than the mean number of words on each page in the math book, the science book has more words per page. Based on the data, is this a valid inference? (1 point)
Question 12 options:
1)
Yes, because there is a lot of variability in the science book data
2)
Yes, because the mean is larger in the science book
3)
No, because the mean is larger in the science book
4)
No, because there is a lot of variability in the science book data
Answer:
4) No, because there is a lot of variability in the science book dataStep-by-step explanation:
Mean absolute deviation is too large for the science book, therefore the mean is not a reliable data to consider.
Since we can't rely on the mean, Maggie's conclusion is not right.

Your friend is
Justify your answer.
Answer:
Step-by-step explanation:
I need more explanation
Volume decreases more when sides are divided than volume divided.
What is volume ?Volume is an amount of a substance that can be stored in a closed place.
Given that,
The volume of a cube is given by V(x) = x³
To verify claim,
Let the side of cube is 4⇒x=4,
Then volume of the cube V= (4)³ ⇒V = 64
According to the condition,
Half of the volume = 64/2 = 32
When side is divided in half, then side x=2
And volume V= (2)³ = 8
This implies that, the volume is more when volume is divided in half than sides are divided in half.
Therefore, friend's statement is wrong.

solve (5w-8)/3 = 4w + 2[
Answer:
w = -2
Step-by-step explanation:
(5w - 8)/3 = 4w + 2
First, we will distribute the division problem on the left.
5w/3 - 8/3 = 4w + 2
Next, subtract 4w from both sides
5w/3 - 8/3 - 4w = 4w + 2 - 4w
We have to turn 4w on the left side into a fraction, but we have to make sure they are like fractions (meaning they have the same denominator).
5w/3 - 8/3 - 12w/3 = 2
5w/3 and -12w/3 are like terms (same variables) so we will subtract -12w/3 from 5w/3
-7w/3 - 8/3 = 2
Now, we will add 8/3 to both sides
-7w/3 - 8/3 + 8/3 = 2 + 8/3
to add 2 and 8/3 together, we need to make them like fractions
-7w/3 = 6/3 + 8/3
-7w/3 = 14/3
Now we get rid of the 3 by mutliplying 3 to both sides
3 * (-7w/3) = 3 * (14/3)
-7w = 14
No we have to divide -7 to both sides
-7w/-7 = 14/-7
w = -2

a family buys 5 airline tickets online. the family buys travel insurance that costs $18 per ticket. the total cost is $955. let z represent the price of one ticket. write an equation for the total cost. then find the price of one ticket.
Answer: Equation that represents this situation is 5(x+17) = 1495,
Price of one ticket is 282
Step-by-step explanation:
Here x represents the price of one ticket,
Also, a person bought travel insurance that costs $17 per ticket.
Hence, the total cost of a person = x + 17
⇒ The total cost of 5 person = 5 ( x + 17 )
But, According to the question,
5 ( x + 17 ) = 1495
⇒ x + 17 = 299
⇒ x = 299 - 17
⇒ x = 282
