Answer:
8.91m/s²
Step-by-step explanation:
If you were referring to the question :
If a 2.2 kg textbook weighs 19.6 newtons on Venus, what is the strength of gravity on that planet then read on.
Weight is the force of gravity on an object and it can be computed using the formula:
W = mg
where:
W = weight (N)
m = mass (kg)
g = acceleration due to gravity
So we know the weight and the mass of the object, all we do is plug it into our formula and solve for what we do not know.
Answer:
y=1/2x-4
Step-by-step explanation:
You are given the slope, 1/2. So you can plug it into the equation (y=mx+b)
You also need to plug in the x and y coordinate your given so you'll have
-3=1/2(2)+b. Then you solve for b, which is -4. You now have your answer, y=1/2x-4.
Area: (2x - 7) * (3*2 + 4x)
(2x - 7) * (6 + 4x)
8x-42
Perimeter: 2(2x - 7) + 2(3*2 + 4x)
The ratio indicates that there are 8 dolls for every 7 teddy bears. That means that if there is 16 dolls, then there is 14 teddy bears. And that if there is 24 dolls, then there is 21 teddy bears. You could continue this pattern, or you could divide and multiply. If you have 160 dolls, then do 160/8 to simplify the ratio. You get 20. So if there is (8x20) dolls, then there is (7x20) teddy bears. 7x20 is 140, so there are 140 teddy bears.

first brand quantity is x
2nd brand quantity is y
x+y=30
0.3x+0.55y=0.35(30) or 0.3x+0.55y=10.5
solve for x and y
multiply first equation by -0.3
-0.3x-0.3y=-9
add to 2nd equation
0.3x-0.3y=-9
<u>0.3x+0.55y=10.5 +</u>
0x+0.25y=1.5
0.25y=1.5
divide both sides by 0.25
y=6
sub back
x+y=30
x+6=30
x=24
you need 24 gallons of the first brand and 6 gallons of the 2nd brand
