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

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
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)
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

Hello There!
So first things first
we need to find the measure of ∠ABD
If you didn´t know the sum of the triangle angles is 180
so to find ∠ABD we subtract the given angles ( 30 and 25) from 180
180-25-30=125
so angle ∠125
Now lets find ∠DBC
∠ABD and ∠ DBC are supplementary angles so the sum of the two angles is 180
So to find ∠DBC we subtract 125 from 180
180-125=55
so ∠DBC = 55
Now we can find the measure of ∠BDC
remember like stated before the sum of all of the angles in a triangle is 180
So to find the measure of ∠BDC we subtract the given angles from 180
180-90-55=35
so we could conclude that ∠BDC = 35
Other ways to solve for ∠DBC:
angle DBC is an exterior angle of ΔABD
the measure of an exterior angle is equal to the sum of the opposite interior angles
so basically ∠DBC = ∠ADB + ∠BAD
30+25=55 so ∠DBC = 55
Other ways to find angle BDC:
Having found the measure of ∠DBA and the other opposite angle we could find ∠BDC
Like stated before the measure of an exterior angle is equal to the sum of the opposite interior angles
basically ∠DBA = ∠BDC + ∠BCA
we have the measures of ∠BCA and ∠DBA so we plug in the values
125=∠BDC+90
isolate the variable by subtracting each side by 90
125-90=35
we´re left with
∠BDC=35
I hope this helps and if you have anymore questions, feel free to ask! :)

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.
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 = $22554336 m : 72 m = 6 sec :____

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]
