Answer:
Step-by-step explanation:
total surface area=3×(1/2×10×6.7)+1/2×10×8.7=3×(33.5)+43.5
=100.5+43.5
=144
Answer:
t=-10
Step-by-step explanation:
-6=t-2/7-5
-6=t-2/2
Cross multiply
-6*2=t-2
-12=t-2
t=-12+2
t=-10
Answer:
y -5 = (3/4)(x -6)
Step-by-step explanation:
Between the two points, the line has a rise of 6 and a run of 8. Thus, the slope is ...
... m = rise/run = 6/8 = 3/4
The point-slope form of the equation of a line with slope m through point (h, k) is ...
... y - k = m(x - h)
For point B, (h, k) = (6, 5), so filling in the values gives ...
... y - 5 = (3/4)(x - 6)
Answer:
50
Step-by-step explanation:
rectangle area = 144 cm
Formula: A= L*H
The give the length which is 16
144 = 16*H
Since they gave u the area instead of the height, work backwards
144/16 = 16/16 *H
9 = H
Now you have the length and height
Length: 16
Height: 9
Perimeter is when you add up all the sides
The top and bottom of the rectangle is the length which is 16 so
16 + 16 = 32
The left and right side of the rectangle is the height which is 9 so
9 + 9 = 18
Now add then both
32 + 18 = 50
So the perimeter of the rectangle is 50
Hope this helped!
