Answer:
hope it helps :D
Let us assume the time after which both singers will charge the smae amount of money = x
Then
50 + 20x = 100 + 10x
20x -10x = 100 - 50
10x = 50
x = 50/10
= 5
So after 5 hours both Singer A and Singer B will charge the same amount of money. I hope the procedure is clear to you and you can attempt such problems in future without needing any kind of help.

Answer:
The equation is y = -5/6 x-4
Step-by-step explanation:
The equation of a line in slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = -5/6 x+b
Substitute in the point
-9 = -5/6(6) +b
-9 = -5+b
Add 5 to each side
-4 = b
The equation is y = -5/6 x-4
p + 2 = 5 ==> p = 3
3p + 2 = p + 3 ==> 2p = 2 ==> p = 1
3k + 5 = 2k + 2 ==> k = -3 (niemożliwe; lewa strona wagi ma większą wagę)
2w + 10 = 4w + 7 ==> 2w = 3 ==> w = 3/2
d + 9 = 3d + 2 ==> 2d = 7 ==> d = 7/2
W drugim zadanie każda litera reprezentuje wagę jednego z obiektów. Na przykład 3k + 4 reprezentuje całkowitą wagę 3 kół i 4 ciężarów, każdy o wadze 1 kg.
Trzecie zadanie to tylko połączenie dwóch pozostałych.
ANSWER
96 yd
EXPLANATION
Let the width of the rectangle be w, then, the length of the rectangle will be:
The area of a rectangle is calculated using the formula:
It was given that, the area of the rectangle is 320yd²
Divide both sides by 5.
Take square root of both sides to get:
This means the length is
The perimeter of a rectangle is given by:
P=2(w+l)
We plug in the values to get:
The perimeter is 96yd

Answer:
AC = 10sin 40°
Step-by-step explanation:
From the diagram attached, using terms in trigonometric ratio, AC is the opposite side, BC is the adjacent side and AB is the hypotenuse.
Thus, since we want to find AC;
We know that in trigonometric ratios; opposite/hypotenuse = sin θ
In the diagram, θ = 40° and AB = 10
Thus,
AC/10 = sin 40°
Multiply both sides by 10 to get;
AC = 10sin 40°
