3/4 X 10= $7.50
Because 3/4 is 75%, 10 is the original price. And 75% times 10 is 7.50<span />
Answer:
x = 7
Step-by-step explanation:
A line perpendicular to the x- axis is a vertical line parallel to the y- axis.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line goes through
The line goes through (7, 13) with x- coordinate of 7, thus
x = 7 ← equation of perpendicular line
Answer:
49.5 square inches
Step-by-step explanation:
We can split the figure into two easier shapes to find the area of; a triangle and a square.
The formula for a triangle is (b*h)1/2. Once we solve we get 24.5 or 24 1/2.
The formula for a square is l*w. Once we solve we get 25.
To find the area of the shaded region, we would add both area and get 49.5 or 49 1/2 square inches.
Answer:
- team: 8 kph
- current: 4 kph
Step-by-step explanation:
The downstream speed is ...
speed = distance / time
speed = 36 km/(3 h) = 12 km/h
The upstream speed is ...
12 km/(3 h) = 4 km/h
__
If b and c represent the speeds of the boat and current, respectively, then we have ...
b + c = 12
b - c = 4
Adding these gives ...
2b = 16
b = 8
c = b -4 = 4
The rate of the rowing team in calm water is 8 km/h; the rate of the current is 4 km/h.
