1. The speed of sound in water is 1,500 meters/second. How far can sound travel in 10
minutes? One hour? Show all calculations.
Answer:
900 km5400 kmStep-by-step explanation:
The speed of sound in water:
s = 1500 m/secTime:
t = 10 min = 10*60 sec = 600 secor
t = 1 hour = 60 min = 60*60 sec = 3600 secDistance in 10 min:
d = s*td = 1500 *600 = 900 000 m = 900 kmDistance in 1 hour:
d = 1500*3600 = 5 400 000 m = 5400 km

Write the equation of the line with x-intercept 3 and passing through the point (5.4)
Answer: y=(1/5)m+3
Step-by-step explanation:
Start with the standard form of an equation of a straight line: y=mx+b, whre m is the slope and b the y-intercept (the value of y when x=0).
y=mx+b
We know b (3), so:
y=mx + 3
To find the slope, m, we can use the one given point, (5,4):
y=mx + 3 for (5,4) would be:
4 = m*5+3
1 = 5m
m = (1/5)
y=(1/5)m+3

Find the midpoint of the line segment joining the points (-1,-1) and (-3,10).
Answer:
[tex](\displaystyle-2,\frac{9}{2} )[/tex]
Step-by-step explanation:
Hi there!
Midpoint = [tex](\displaystyle\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex] where the two endpoints of the line segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the endpoints (-1,-1) and (-3,10):
[tex](\displaystyle\frac{-1+(-3)}{2} ,\frac{-1+10}{2} )\\\\(\displaystyle\frac{-4}{2} ,\frac{9}{2} )\\\\(\displaystyle-2,\frac{9}{2} )[/tex]
I hope this helps!
if ab=12 and a^2+b^2=25 ,then what is (a+b)^2=
Answer:
49
Step-by-step explanation:
Multiply out (a+b)^2
(a+b)^2 = (a+b)(a+b) = a^2 + ab + ba + b^2 ; not ab = ba so,
= a^2 + 2ab + b^2 = a^2 + b^2 + 2ab ; now subtitue in given values
=25 + 2(12) = 25 + 24 = 49
So (a+b)^2 = 49

In kick boxing, the force needed to break a board varies inversely with the length of the board.If it takes 5 pounds of pressure to break a board 2 feet long, how many pounds of pressure will it take to break a board that is 8feet long?
Answer:
Step-by-step explanation:
By taking k as constant:
P = k/L (where P is pressure, and L is length)
5 = k/2
k = 10
Therefore:
P = 10 / L
P = 10/ 8
P = 1.25 Pounds.

The ratio of quarters to dimes in a money bag is 21:18. If the total number of coins is 147,how many dimes are there?
21 + 18 = 39
147/39 = 3.7692307692307
3.7692307692307 x 18 = 67.846153846152, round to 67.80 and that's your answer
Evaluate: [(1/2)^2-(1/4)^3]
Answer:
15/64
Step-by-step explanation:
Evaluate:
[(1/2)²-(1/4)³]
We have to find the value of expression ?
Explanation:-
Given that
[(1/2)²-(1/4)³]
⇛ [{(1/2)×(1/2)}-{(1/4)×(1/4)×(1/4)}]
⇛ [{(1×1)/(2×2)}-{(1×1×1)/(4×4×4)}]
⇛ [(1/4)-(1/64)]
LCM of 4 and 64 = 64
⇛ [(1×16)-(1×1)]/64
⇛ (16-1)/64
⇛ 15/64
The value of the given expression is 15/64.

Explain step by step of how you would find the scale factor for the following problem.
Answer:
Scale factor = 2.5.
Step-by-step explanation:
Work out the lengths of the corresponding sides.
The scale factor is the ratio of one side to the other.
Take the smallest length in both triangles.
Blue triangle:
length = √((7.5-2.5)^2 + (12.5-5)^2) = 9.0139 units.
Red triangle:
length = √((3-1)^2 + (5-2)^2) =3.6056
So the scale factor
= 9.0139/ 3.6056
= 2.5.
ABCD is a parallelogram and X and Y are any point on CD and AD respectively. Prove that triangle AXB and triangle BYC are equal in area. Prove that
Answer:
See answer below
Step-by-step explanation:
ABCD is a parallelogram Given
BC ≅ AD; AB ≅ DC opposite sides of a parallelogram ≅
Δ AXB = 1/2 (AB)(AD) Formula for the area of a Δ
Δ BYC = 1/2 (BC) (DC) Formula for the area of a Δ
1/2 (AB)(AD)= 1/2(BC)(DC) Substitution
∴ Area of Δ AXB = Area of ΔBYC

a=V^2/P make v the subject
Answer:
correcto
Step-by-step explanation:
Answer:
v = sqrt(a*p)
Step-by-step explanation:
multiply both sides by p
a*p = v^2
square root both sides to get rid of the (^2) on the v
then you'll be left with v= sqrt(a*p)
