HERE IS THE FULL PROBLEM!!!!
the table below lists four names and their corresponding aproximant weights on earth.
________________________________
mass (kilograms) | weight (newtons)
20 | 196
50 | 490
x | 1078
130 | 1274
140 | 1372
the ratio weight to mass in contant. wich statemen describes the ratio of weight to mass and the value of x in the table?
A. 98/10; X =90
B. 98/10; =110
C. 10/98; X =90
D. 10/98; X= 110
Answer:
20
Step-by-step explanation:
The midsegment of a trapezoid is calculated as
=
=
= 20
The answer is D to the next step
Answer:
Height of fir tree = 9 meters
height of pine tree= 12 meters
Step-by-step explanation:
The combined height of one fir tree and one pine tree is 21 meters. The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.
Let x be the height of fir tree and y be the height of pine tree

Subtract x from both sides

height of 4 fir trees = pine tree +24

Substitute 21-x or y in the above equation

Add x on both sides

Divide by 5 on both sides
x=9
Now plug in 9 for x and find out y


y=12
Height of fir tree = 9 meters
height of pine tree= 12 meters
