Brandon is playing hide-and-seek with Katy and Tony. Katy is hiding 63 feet south of Brandon, and Tony is hiding due east of Katy. If Brandon is 87 feet from Tony, how far apart are Katy and Tony?
Answers
Answer:
60 feets
Step-by-step explanation:
Given that :
Using Pythagoras rule :
Hypotenus = sqrt(Adjacent^2 + opposite^2)
From the attached picture :
x² = 87^2 - 63^2
x^2 = 7569 - 3969
X^2 = 3600
Take the square root of both sides :
X = sqrt(3600)
X = 60 feets
Hence, Katy and Tony are 60 feets apart

x=2.5 for the second question!
x= -8.3 repeating for the 5th question
Step-by-step explanation:
Answer:
1. x = 9
2. x = 5/2
3. x = -64
4. x = -20
5. x = -5
6. x = 19
7. x = -6
Step-by-step explanation:
1.
-3x + 9 = -18
-3x = -27
x = 9
2.
2x - 14 = -9
2x = 5
x = 5/2
3.
x/2 + 8 = -24
x/2 = -32
x = -64
4.
-2.5x - 10 = 40
-2.5x = 50
x = -20
5.
-6x - 10 = 20
-6x = 30
x = -5
6.
50 = 2x + 12

Which proportion could be used to find the length of side b?

Answers
Answer: Choice C) [tex]\frac{\sin(23)}{6.2} = \frac{\sin(85)}{b}[/tex]
=========================================================
Explanation:
The angle opposite side b is 85 degrees. So we'll involve either the fraction [tex]\frac{\sin(85)}{b}[/tex] or [tex]\frac{b}{\sin(85)}[/tex]. In this case, we will use the first fraction. This is due to all of the answer choices having sine on top.
The other fraction must have sine on top as well.
The known side is AB = 6.2; the opposite angle is C = 23 which you find by solving A+B+C = 180 and plugging in A = 72 and B = 85.
So the other fraction we'll use is [tex]\frac{\sin(23)}{6.2}[/tex]
Overall, the proportion we can set up is
[tex]\frac{\sin(23)}{6.2} = \frac{\sin(85)}{b}[/tex]
which points to choice C as the final answer.

This venn diagram represents the science subjects studied by students what is the probability that a student,chosen at random,studies physics and chemistry or both ?
Answers
Answer:
Step-by-step explanation:
Looking at the Venn diagram :
The total number of students surveyed is 7+5+8+6+2+4+3+6 = 41
The number of students that studies physics is = 14
The number of students that studies chemistry is = 21
Probability = number of favorable outcomes / total number of outcomes
Therefore the probability that a student chosen at random studies physics and chemistry or both is 35/41 = 0.85
If Roger ran 5 miles in 150 minutes, Ryan ran 10 miles in 300 miles, and Rick ran 5 miles in 2 and ½ hours, who had the best rate of running(fastest time)?
Answers
Answer:
All three have same rate of running.
Step-by-step explanation:
Given that:
Distance covered by Roger = 150 minutes
Time taken by Roger = 5 miles
Distance covered by Ryan = 300 minutes
Time taken by Ryan = 10 miles
Distance covered by Rick = 2[tex]\frac{1}{2}[/tex] hours
Time taken by Rick = 2 miles
To find:
Who has the fastest rate of running?
Solution:
First of all, we need to convert the time in hours and then we need to apply the formula for relation between Speed, time and distance.
Then we can compare the Speed.
60 minutes = 1 hour
150 minutes = [tex]\frac{1}{60} \times 150 = 2.5\ hours[/tex]
300 minutes = 5 hours
Formula for Speed:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Rate of running (speed) of Roger = [tex]\frac{5}{2.5}[/tex] = 2 miles/hr
Rate of running (speed) of Ryan = [tex]\frac{10}{5}[/tex] = 2 miles/hr
Rate of running (speed) of Rick = [tex]\frac{5}{2.5}[/tex] = 2 miles/hr
Therefore, All three have same rate of running.

Answer:
∠1 = 40
Step-by-step explanation:
So due to the alternate interior angles theorem, angle 1 and angle 2 equal each other so:
2x + 20 = 3x + 10
subtract 2x from both sides
20 = x + 10
subtract 10 from both sides
10 = x
Now input 10 into the equation
2(10) + 20
20 + 20
40

Answers
Answer:
Hope it helps) and HAPPY NEW YEAR MY DEAR
Step-by-step explanation:
Let A be the number of cards Alan has
B be the number of cards Bill has
C be the number of cards Calvin has
Alan had 11 less than 2 1/2 times the number of cards bill has.
is 2.5
Alan is 2.5 of bill has minus 11
A=2.5B -11
Calvin has 1 more than 1 1/2 times the number of cards bill has.
is 1.5
Calvin is 1.5 of bill has plus 1
C=1.5B + 1
Alan and Calvin have the same number of cards
So A=C
WE plug in A and C equations and solve for B
2.5B -11 = 1.5B + 1 (subtract 1.5B on both sides)
1B -11 = 1 (Add 11 on both sides)
B = 12
If Alan and Calvin have the same number of cards, the number bill has is 12
The number of cards Alan and Calvin each have is 19
Total cards = 12 + 19 + 19 = 50
If Alan, bill, and Calvin have all the cards in the deck then the deck has 50 cards.

Interpretation of axes and scales:
The horizontal axis (x-axis): There is time in seconds on the horizontal axis
Scale: 1 unit in the x-axis = 1 second
The vertical axis (y-axis): There is the distance in feet which is the height of the elevator from the ground on the horizontal axis
Scale: 1 unit in the y-axis = 20 feet
Interpretation of the origin:
The coordinate is represented by the point (0,0) in the graph. This means at time = 0 the height of the elevator =0, i.e the elevator is on the ground at the starting time.
