Alyssa can complete a job in 12 minutes. If Miranda helps her, they can complete the job in 9 minutes. How long would it take Miranda to complete the job by herself? (In minutes.) Rate of work problem
Answer:
36 minutes
Step-by-step explanation:
The key is to get the same amount of time for each.
9 * 12 = 108
At 12 minutes per job,
in 108 minutes Alyssa could do
108/12 = 9 jobs
At 9 minutes per job,
Together in 108 minutes they could do
108/9 = 12 jobs
--------------------------
In 108 minutes Mirada does
12 - 9 = 3 jobs
108/3 = 36 minutes per job
A firefighter is on the fifth floor of an office building. She needs to throw a rope into the window on the seventh floor, 40 feet above her. If she throws the rope upward with an initial velocity of 36 ft/s, will the rope get to the window.
Answer:
no, it wont
Step-by-step explanation:
2g.h = v²
2(33)(40) = v²
2640=v²
v=√2640 = 51.38 ft/s
36 < 51.38
so, the rope will not get to the window

Lesley purchased 5 beads at a total cost of 80 cents. The round beads cost 15 cents each, and the oval beads cost 20 each. The equations and graph below can be used to determine the number of each type of bead kesley purchased. Where x represents the number of round beads and y represents the number of oval beads. What are the numbers of round and oval beads Kelsey purchased?
Answer:
Lesley purchased 1 oval bead and 4 round beands.
Step-by-step explanation:
Given that Lesley purchased 5 beads at a total cost of 80 cents, and the round beads cost 15 cents each, and the oval beads cost 20 each, to determine what are the numbers of round and oval beads Kelsey purchased, the following calculation must be performed :
5 x 0.20 + 0 x 0.15 = 1
4 x 0.20 + 1 x 0.15 = 0.95
2 x 0.20 + 3 x 0.15 = 0.85
1 x 0.20 + 4 x 0.15 = 0.80
Therefore, Lesley purchased 1 oval bead and 4 round beands.
Given TU = 7.4. what is PS in OC? Round to the nearest tenth.
Answer:
3.7
Step-by-step explanation:
TU= 7.4
PS is half of TU, so we divide 7.4 by 2.
The value of the PS in OC will be 3.8 Phythogorous theorem is applied in the triangle PSC to solve the problem.
What is the definition of geometry?It is concerned with the geometry, region, and density of various 2D and 3D shapes.
Joining the point p to c, resulting in pc being the circle's radius and equal to CQ's radius.
Take a look at the PSC triangle now. In the right angle triangle, PSC apply phythogorous theorem.
PC²=PS²+SC²
(5.1)²=PS²+(3.4)²
26.01=PS²+11.56
PS²=26.01-11.56
PS=√(14.45)
PS=3.8
Hence, the value of the PS in OC will be 3.8

Step-by-step explanation:
The average rate of change from day 2 to day 10 is given by the slope of the line m =
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The number of houses sold on day 2 is P
The number of houses sold on day 10 is Q
Let the first point be P ( 2 , 8 )
Let the second point be Q ( 10 , 2 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2 - 8 ) / ( 10 - 2 )
Slope m = -6/8
m = -3/4
Therefore , the number of houses sold between day 2 and 10 is -3/4 houses per day
Hence , the slope is m = -3/4 houses per day

What is the diameter of a hemisphere with a volume of 5990in^3 to the nearest tenth of an inch?
Answer:28.4
Step-by-step explanation:
Delta Math
The diameter of the asked hemisphere is 28.38 in.
What is hemisphere?The half of a sphere is called a hemisphere.
Given that, a hemisphere with a volume of 5990 in³
Volume of a hemisphere = 2/3πr³
2/3πr³ = 5990
r³ = 5990x7x3/22x2
r³ = 125790/44
r³ = 2858.8636
r = 28.38

Find all real solutions of the equation (x-5)^2-4=0 real solutions=?
Answer:
x = 7
x = 3
Step-by-step explanation:
(x - 5)² - 4 = 0
Take the (x - 5)² and foil it. By doing that, you're going to set them both against each other to multiply. The squared part means that (x - 5) is being multiplied by itself. Like so:
(x - 5) (x - 5)
Multiply the x by the x, the x by the -5, the -5 by x, and the -5 by -5.
The x times x would be x². The x times -5 would be -5x. The -5 times x would be -5x. And the -5 and -5 would be 25.
To put it in an equation: x² - 5x - 5x + 25 - 4
Simply the equation: x² - 10x + 21
Now that it's a quadratic equation, we can factor. Looking at the final term, the 21, we can find factors of 21 that add up to -10, which would be -7 and -3. They both multiply to a positive 21 and add up to a -10.
Taking this new information, we can split the equation up like so: (x -7), (x - 3)
Set both equations equal to 0.
So: x - 7 = 0
Add seven to both sides.
x = 7
x - 3 = 0
Add three to both sides
x = 3
Final Answer: x = 3, x = 7, both are real solutions
