0. The weight of an object on the Moon is about 16.5% of its weight on Earth. The weight of an astronaut on the Moon is 24.75 pounds. How much does the astronaut weigh on Earth?
Answer: 150 pounds
Step-by-step explanation:
Let the the astronaut weight on Earth be represented by x.
Based on the information given in the question, thus can be formed into an equation as:
16.5% of x = 24.75
16.5% × x = 24.75
16.5/100 × x = 24.75
0.165x = 24.75
x = 24.75/0.165
x = 150 pounds
The astronaut weigh 150 pounds on Earth.
if cos ø = -4/7 what are the values of sin ø and tan ø
Answer:
tan=5,5
sin=0,98
Sry when Its wrong
Answer:
sin• = √13/7
tan•= -√13/4
Step-by-step explanation:
sin2•+ cos2• = 1
sin• = √1-cos2•
sin•= √1-(-4/7)2
sin•= √1-16/49
sin•= √ 49-16/49
sin•= √ 13/ 49
sin•= √13/7
tan• = sin•\cos•
= √13/7/-4/7
= -√13/4

Answer:
umm, i can't read it
Step-by-step explanation:
Answer what you can please and show work. I will mark you brainliest.
Answer:
part 1:
1) AB = BC = 10
2) DE = sqrt(10² - 9²) = sqrt(19)
3) CED = 90⁰
4) BCD = (90⁰ - 53⁰).2 = 74⁰
part 2:
because FGHJ is a rhombus
=> GK = KJ
<=> 3x + 1 = x + 9
<=> 2x = 8
<=> x = 4
and we have:
GHK + FGK = 90⁰
<=> (4y - 8)/2 + y + 4 = 90⁰
<=> 2y - 4 + y + 4 = 90⁰
<=> 3y = 90⁰
<=> y = 30
5) with x = 4 => GJ = 2KJ = 2.(4 + 9) = 26
6) JK = 4 + 9 = 13
7) with y = 30, HFJ = 90 - FGK = 90 - 34 = 56⁰
8) HJF = 2.FGK = 2.34 = 68⁰
part 3:
because MNLO is rectangle
=> MP = PO
<=> 5a - 7 = 2a + 8
<=> 3a = 15
<=> a = 5
9) with a = 5, MO = 2.PO = 2.(2.5 + 8) = 2.18 = 36
10) NP = PO = 2.5 + 8 = 18
11) LM² = LN² - MN² = MO² - 26² = 36² - 26² = 620
=> LM = 2sqrt(156) = 24,9
12) tan NMO = NO/MN = LM/MN = 24.9/26
=> NMO = 43,8⁰
part 4:
because RSTU is square
=> SR = RU
=> 2k + 7 = 3k - 2
<=> k = 9
with k = 9 =>RU = SR = 2.9 + 7 = 25
13) RV = 1/2.SU = 1/2.sqrt(25² + 25²) = 17,7
14) SU = 2RV = 2.17,7 = 35,4
15) perimeter RSTU = 25.4 = 100
16) area RSTU = 25² = 625

2. The following list of prices is for a used original radio for a 1955 Thunderbird. The prices vary
depending on the condition of the radio.
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
a. Find the mean of the radio prices. Round to the nearest cent.
Answer: $275
Step-by-step explanation:
The mean of the radio price is $275 or 27500 cents
Given,
Price of used original radio for a 1955 Thunderbird:
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
We need to find the mean of these prices.
And round to nearest cent.
What is the mean of a set of values?The mean is the average of all the given sets of values.
Example:
1,2,3,4
Mean = (1+2+3+4) / 4 = 10/4 = 2.5
Find the sum
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
Sum=(210+210+320+200+300+10+340+300+245+325+700+250+240+200)
Sum = 3850
Find the number of prices.
= 14 prices
Find the mean.
= 3850 / 14
= 275
The mean radio price is $275.
Converting into cents.
$1 = 100 cents
$275 = 27500 cents
Thus the mean of the radio price is $275 or 27500 cents

Chipotle Burritos are normal distributed with a mean length of 200mm and a standard deviation of 8mm. What is the probability that a burito picked at random is shorter than 190mm?
Answer: 0.1056
Step-by-step explanation:
Given: Chipotle Burritos are normal distributed with
Mean = 200 mm
Standard deviation = 8 mm
Let x be the length of a random burrito.
The probability that a burrito picked at random is shorter than 190mm will be :
[tex]P(x<190)=P(\dfrac{x-\mu}{\sigma}<\dfrac{190-200}{8})\\\\=P(z<-1.25)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z<1.25)\\\\=1-0.8944\\\\=0.1056[/tex]
Hence, the probability that a burrito picked at random is shorter than 190mm is 0.1056.

A company rents out 14 food booths and 26 game booths at the county fair. The fee for a food booth is $175 plus $8 per day. The fee for a game booth is $65 plus $7 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
The expression is ________
Answer:
$4140 + $294d
Step-by-step explanation:
Hello,
Let's write down what we know first,
d days
14 food baths -- $175 and $8 per day
26 game booths -- $65 and $7 per day
What we want to find the amount of money paid for both food baths and game booths so after finding them individually, we need to add them up.
We already know the company rents out 14 fb and 26 gb and we know that each fb is 175 dollars and each gb is 65 dollars, so we should find out the cost of buying them. We can also write out the total cost of
14 * $175 = $2450
26 * $65 = $1690
Now lets find the per day cost,
14 * $8 * d = $112d
26 * $7 * d = $182d
With both equations added together we get,
$2450 + $112d
$1690 + $182d
Add those together and we get:
$4140 + $294d

For questions 1-4, find the distance between points A and B. Round your solutions to the nearest tenth when necessary.
Answer:
1. AB= 8.94,
2. AB= 7.28
3. AB= 16.4
4. AB= 19.21
Step-by-step explanation:
This is fun! Well you have to find the (1,4) (or point e) point and count the distance to the other points point a and point b.
4 units from a to e and 8 b to e
a² + b² = c²
8² + 4² = c²
64 +16 = c
√80 = √c²
8.94 = c
It dose not matter which units you plug in for a and b but c has to be the long side of the triangle/ hypotonuse.
Follow the same steps for the rest of the problems.
On proplems 3 and 4 plot points first you can subtract the x-x and y-y as a short cut to find the units.
