Answer:
C is correct
Step-by-step explanation:
Fill in the blank below with a number. Puffin is travelling through the mazes of Galaxiconia and drops a stone into a deep, dark well.Let be the number of seconds it took before he heard the sound of it hitting the bottom.Then the number of metres the rock fell is given by 5w x w If the rock took seconds to hit the bottom, then the well is (answer) metres deep.
Answer:
Depends on what w is determined as, for example, if w = 4 then the answer would be 80
Step-by-step explanation:
Basically since there is a w next to the 5 we can make the equation 5 x w x w, since 4 = w, it makes the equation 5 x 4 x 4, next we can do 4 x 4 which gives us 16, you could also do 5 x 4 which equals 20, then we do 16 x 5 or 20 x 4 which equals 80 and there is your answer. This basically applies to all numbers as long as it is [number x w x w] and [w = number] no matter how you change the sequence you get the same answer.

Line Ris represented by the equation y ==x+2. Line S is perpendicular to Line R, and passes through
the point (-6,4). What is the equation for Line S?
A. y =
B. y = x +6
C. y=-*-5
D. y = -x + 8
Answer:
y = -x - 2
Step-by-step explanation:
y = x + 2 {Compare with y = mx + c}
Slope = m1 = 1
Slope of the line S = m2 = -1/m1 = -1/1 = -1
(-6 , 4)
y -y1 = m (x -x1)
y - 4 = (-1)(x - [-6] )
y -4 = (-1)(x + 6)
y -4 = (-1)*x + (-1) *6
y - 4 = -x - 6
y = -x - 6 + 4
y = -x - 2

Answer:
-13
Step-by-step explanation:
Well, they do most of the work for you all you have to figure out is what is "1/5(-65)". To do this you have to turn 1/5 into a decimal so 1 divided by 5 which equals 0.2 then multiply that by -65. That will give you your simplified answer of -13.

Answer:
a³-b³= (a-b)(a²+ab+ b²)
Step-by-step explanation:
Solve the following system of equations:
4x + 3y = 17
3x + 2y = 13
ANSWER:
(x,y) = (5,-1)
Answer:
(5, -1)
Step-by-step explanation:
Solve the system of equations by elimination.
4x + 3y = 17
3x + 2y = 13
Multiply the top equation by -3 and the bottom equation by 4:
-12x - 9y = -51
12x + 8y = 52
Add these together:
-y = 1
y = -1
Plug in -1 as y into one of the equations, and solve for x:
4x + 3y = 17
4x + 3(-1) = 17
4x - 3 = 17
4x = 20
x = 5
So, the solution is (5, -1)

Answer:
Linear relationship with negative slope
Step-by-step explanation:
This is a linear a linear relationship because most of the points are plotted in a line
It has a negative slope because it goes downwards from left to right which indicates that it has a negative slope
Answer:
B)
Step-by-step explanation:
The scatterplot makes a linear line starting in the top left and ending in the bottom right, meaning this slope is negative.

Beth Ann practiced piano for 1 hour 5 minutes each day for 1 week. She had 5 songs to practice and spent the same amount of time practicing each song. How long did she practice each song during the week?
Answer:
91 minutes per song in a week
Step-by-step explanation:
1 hour 5 minutes each day = 65 minutes per day
Total time spent on practicing piano in a week = 7 × 65 minutes
= 455 minutes
She had 5 songs to practice and spent the same amount of time practicing each song
Amount of time to practice each song = Total time spent on practicing piano in a week / number of songs
= 455 minutes / 5
= 91 minutes per song in a week
Equivalent to 1 hour 31 minutes
roup of softball players are training on a square-shaped sports ground with sides measuring 100 yards each. The players run around for 10 minutes to warm up. How many laps around the sports ground do they run given their average speed is 5 yards per second? Please add an explanation. I will mark the brainliest to whoever's answer is best and YOU GET 50 Points.
Answer:
7.5 laps
Step-by-step explanation:
First, you wanna figure out how many yards is in one lap
to do this, you would multiply 100 and 4 (four because there's four equal sides in one lap)
100 x 4 = 400
You know their speed is 5 yards per second, so you wanna find out how many seconds they will be running
to do this, you multiply 60 (sixty because there's sixty seconds in one minute) and 10 (ten because that's the given amount of minutes)
60 x 10 = 600 seconds
now to found out how much they will run in 10 minutes you will multiply 600 by 5
600 x 5 = 3000 yards
now to find how many laps this is, you can divide 3000 yards by 400 yards
3000 ÷ 400 = 7.5 laps

The geometric mean of x+3 and 4x+1 is 2x+1. Find all possible values of x.
Answer:
[tex] x = - \frac{2}{9} [/tex]
Step-by-step explanation:
Since, the geometric mean of x+3 and 4x+1 is 2x+1.
Therefore, by geometric mean theorem:
[tex] {(2x + 1)}^{2} = (x + 3)(4x + 1) \\ \\ \cancel{4 {x}^{2}} + 4x + 1 = \cancel{4 {x}^{2}} + x + 12x + 3 \\ \\ 4x + 1 = 13x + 3 \\ \\ 4x - 13x = 3 - 1 \\ \\ - 9x = 2 \\ \\ x = - \frac{2}{9} [/tex]

annual sales for a company are $149,999 and are increasing at a rate of 6% per year. write an exponential growth function to model this situation. then, find the annual sales after 7 years.
Answer:
S(t) = 149999(1.06)^t$225543Step-by-step explanation:
Initial value is $149999Increase rate is 6% per year = 1.06 timesThe model of the growth is:
S(t) = 149999(1.06)^t, where S- amount of annual sales, t- time in years, 1.06- growth rate per yearAnnual sales after 7 years:
S(7) = 149999(1.06)^7 = $225543If the sum of two numbers is 67, and there difference is 33. The largest number is what?
