Answer: 5:10 A.M.
Step-by-step explanation:
First find the total time that Isabelle spent playing volleyball and hiking.
= 2 hours and 10 minutes + 1 hour and 55 minutes
= 4 hours and 5 minutes
If she finished both activities at 11:15 am, the time she started was:
= 11:15 - 4 hours 5 minutes
= 5:10 A.M.
does a triangle with side lengths 10, 49.5, and 50.5 form a right triangle ?
Answer:
yes
Step-by-step explanation:
Use Pythagorean Theorem:
10² + 49.5² = 50.5² ??
100 + 2450.25 = 2550.25
2550.25 = 2500.25

A climber is ascending the face of a 500-foot high vertical cliff at 5 feet per minute. Her climbing partner is observing from 150 feet away. Find the function that describes the amount of time climbing as a function of the angle of elevation of the observer’s line-of-sight to the climber. Does the viewing angle ever reach 75 degrees?
Answer:
a) t (α) = 30 * tan α
b) α = 75 ° is not possible because
Step-by-step explanation:
The vertical cliff (y), the observing partner ( 150 ft ) from the point o ( the common point for the cliff and the ground ) between the cliff, and the line of sight from the observer and the climber, shape a right triangle. Hypothenuse is the distance between the partners, the cliff, and distance of the observer to the cliff are the legs.
Then
α is the elevation angle
tan α = y / 150 (1)
y(t) = elevation of the climber
y(t) = speed * time
y(t) = 5 * t
tan α = 5 *t / 150
tan α = t / 30
t (α) = 30 * tan α
b) α = 75 ° is not possible because:
tan α = y / 150 tan 75° = 3.73
Then y = 3.73 * 150 = 559 ft and the cliff is only 500 ft

Use a formula to find the amount of wrapping paper you need to wrap a gift in the cylindrical box shown. You need to cover the top, bottom, and all the way around the box. Use 3.14 for .
Answer:
Total wrapping paper need = 960.84 inch²
Step-by-step explanation:
Given:
Height of cylinder box = 8 inch
Radius of cylinder box = 9 inch
Find:
Total wrapping paper need
Computation:
Total wrapping paper need = Total surface area of cylinder
Total surface area of cylinder = 2πr(h + r)
Total wrapping paper need = 2[3.14][9][8+9]
Total wrapping paper need = 2[3.14][9][17]
Total wrapping paper need = [6.28][9][17]
Total wrapping paper need = [56.52][17]
Total wrapping paper need = 960.84 inch²

if p (n,3)=1320what is n
Answer:
n=12
Step-by-step explanation:
lol we meet again
just use the permutation formula for this one.
n!/(n-3)!=1320
[n×(n-1)×(n-2)×(n-3)!]/(n-3)!=1320
n(n-1)(n-2)=1320
(n²-n)(n-2)=1320
n³-3n²+2n-1320=0
n=12
Rahul, a coach at a local school has collected data on his players. But in an accident he lost how many games each player participated in. He knows that per game Michael played 30 minutes, had 1 foul, and 2 goals. Per game, Sherry played 25 minutes, had 1 foul, and 5 goals. Rashad played 20 minutes, had 2 fouls, and 4 goals per game. Rahul also knows that the total amount of all three players. Together they played 370 minutes, had 20 fouls, and 58 goals. Can you use algebra to determine how many games each athlete played in
Answer:
Michael played 4 games, Sherry played 6 games and Rashad played 5 games
Step-by-step explanation:
Let X, Y and Z represents the number of games for the three players.
Based on the given information, three equations can be formed -
30 X + 25 Y + 20 Z = 370 ---(1)
X + Y + 2Z = 20 ---(2)
2X + 5Y + 4 Z = 58 ---(3)
From Equation (2), X = 20 -Y-2Z
Substituting value of X from equation 2, in equation 1 and 2, we get -
30 (20-Y-2Z) + 25 Y + 20 Z = 370
600 -30Y-60Z + 25 Y + 20 Z = 370
-5Y -40Z = -230
Y + 8Z = 46 ----(4)
2(20-Y-2Z) + 5Y + 4 Z = 58
40 -2Y-4Z + 5Y + 4 Z = 58
3Y = 18
Y = 6
Substituting value of Y in equation 4, we get -
8Z = 46-6
8Z = 40
Z = 5
Substituting value of Y and Z in equation 2 we get
X + 6 + 2* 5 = 20
X = 20-16 = 4
Hence, Michael played 4 games, Sherry played 6 games and Rashad played 5 games
Solve for the Hypotenuse of the Right Triangle in the Diagram below. C = ?, a = 5, b = 12
•25
•144
•169
•13
Answer:
13 is the correct answer. Remember the equation c = √(a² + b²)
i seriously need help to pass this test!!
Question 1 options:
A 30°-60°-90° triangle has a shorter leg with a length of 14 cm. The hypotenuse of the triangle is ___ cm
From now on, remember that the smallest side in a triangle is always facing the smallest angle of the triangle.
_________________________________
The question told us that the shorter leg has a measure of 14 in which it is tha smallest side of the triangle thus 14 is the facing side to the 30 degrees angle .
As we know, in a right-angled triangle, the facing side to the angle of 30 degrees has half measure of hypotenuse. So :
1/2 × hypotenuse = 14
Multiply both sides by 2
hypotenuse = 28
Find the area of the regular polygon.
The perimeter of 14 and radius of 2.5
Answer:
The area of the regular polygon is 17.5.
Step-by-step explanation:
To find the area of the regular polygon with a perimeter of 14 and radius of 2.5, the following calculation must be performed, knowing that the area of a regular polygon arises from multiplying the perimeter by the apothem divided by two:
(14 x 2.5) / 2 = X
35/2 = X
17.5 = X
Therefore, the area of the regular polygon is 17.5.
Which function represents transforming ƒ(x) = 3x with a reflection over the x-axis and a vertical shift of 4 units?
A) h(x) = 3x + 4
B) h(x) = -3x + 4
C) h(x) = 3x-4
D) h(x) = -3x+4
Answer:
B. h(x) = -3x + 4.
Step-by-step explanation:
I am assuming that the vertical shift is upwards,
A refection in the x axis gives -3x
Vertical shift upwards of 4 gives -3x + 4.

DONT MINF MY PRO CROPPING. DEFF.
ALSO ITS NOT A
Answer:
I believe it's C
Step-by-step explanation:
The surface area of the bottom is 64 because it's 8 times 8.
All of the sides are 8 times 12.
8 times 12 is 96.
96 times 4 (for all four sides) is 384.
So the sides (384) plus the bottom (64) is 448, or C

Find each missing measure.
Answer:
m∠E= 37°
m∠F=37°
Step-by-step explanation:
Total angle value: 180°
180-106=74
The lengths are the same, so we can determine that the angles E and F are the same. So we divide 74 by 2
74/2= 37
m∠E= 37°
m∠F=37°

Answer:
105 m²
Step-by-step explanation:
Dividing the figure into 3 rectangle will be easier to find its area.
The area of the larger rectangle
= (10-5) × 13
= 65 m²
The total area of the 2 smaller rectangles
= 2 × (4×5)
= 40 m²
The area of the figure
= 65 + 40
= 105 m²

Standardized tests for certain subjects, given to high school students, are scored on a scale of 1 to 5. Let X represent the score on a randomly selected exam. The distribution of scores for one subject’s standardized test is given in the table.
A 2-column table with 5 rows. Column 1 is labeled score with entries 1, 2, 3, 4, 5. Column 2 is labeled Probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.
What is the probability of earning a score of 3 or higher?
0.26
0.36
0.62
0.66
Answer:
C. 0.62
Step-by-step explanation:
probability of earning a score of 3 or higher means the probability we are trying to find includes 3,4,5 so we just add these together to get the probability of 3 and above
3 = 0.26
4= 0.21
5= 0.15
0.26+0.21+0.15= 0.62
Sasha runs at a constant speed of 3.6 meters per second for
1/2 hour. Then, walks at a rate of 1.6 meters per second for
1/2 hour. How far did run and walk in 60 minutes?
Step-by-step explanation:
Distance covered = speed × time.
Sasha runs at a constant speed of 3.8 meters per second for 1/2 hour.
This means distance covered while running would be
3.8 × 1/2 = 1.9 meters
Then she walks at a constant rate of 1.5 meters per second for 1/2 hour. This means distance covered while walking would be
1.6 × 1/2 = 0.8 meters
Total distance that Sasha covered while running and walking in 60 minutes would be
1.9 + 0.8 = 2.7 meters
