Answer:
37in.^2
Step-by-step explanation:
So if the triangles at the top have a hypotenuse of 5, and a length of 4, then doing reverse Pythagorean theorem, you find out that the width is 3.
. so reverse of that for this problem would be 
and if we plug it in, we get 25 -16=9 and the square root of 9 is 3. so if we find the are of the triangle, 3*4*1/2=6 and there are 2 triangles so 12 for both triangles. The square is 5*4=20. and the smaller triangles on the side are 1*5*1/2=2.5, and there are 2 traingles so 2.5*2= 5. So 5+20+12=37. You can do this on most calculators, and please put my answer as the brainliest.✌
Answer:
W=191,000MWH S=27,000MWH
Step-by-step explanation:
OK, let's W be wind electricity generated and S, solar electricity generate.
TOTAL GENERATED: <u>218,000mwh = W + S </u>
RELATION BETWEEN W AND S: <u>W = 2,000mwh + 7S</u>
We have now two equations:
218,000 = W + S
W = 2,000 + 7S
Put th value of W into the 1st equation in order to find S:
218,000 = 2,000 + 7S + S
218,000 = 2,000 + 8S
218,000 - 2,000 = 8S
216,000 = 8S
S = 216,000/8
S = 27,000mwh
Now, we find W.
W = 2,000 + 7*27,000mwh
W = 2,000 + 189,000mwh
W = 191,000mwh
Answer:
157286400 bacteria
Step-by-step explanation:
We are given the following in the question:
The bacteria increases 4 times every 6 hours.
Initially there are 150 bacteria.
Thus, we can write the function for number of bacteria after x hours,
We have to find the number of bacteria in 2.5 days.
1 day = 24 hours
Thus,
Putting x = 60 in the above equation, we get,
Thus, there will be 157286400 bacteria in two and a half days.
Hello!
The equation, y = mx + b is slope-intercept form. In this equation, m is the slope, and b is the y-intercept.
If the baby was exactly 8 pounds when it was born, then the y-intercept is (0, 8) because at zero months, the baby was eight pounds. To find the rate of change, we can use the the y-intercept (0, 8), and the weight of the baby at four months, which is (4, 8 + 3) → (4, 11).
Since we have two points, we can use the slope formula 
to find the rate of change.
.
The rate of change is 3/4.
Therefore, the equation that describes the baby's weight is y = 3/4x + 8.
