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: 218,000mwh = W + S
RELATION BETWEEN W AND S: W = 2,000mwh + 7S
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:
y = 40x
Step-by-step explanation:
Given - Alex walks from her home to the bus stop at a rate of 40 steps per minute.
To find - Write a rule they gives her from home in steps as a function of time after she leaves her home.
Proof -
The function will be a linear function.
The linear function is in the format of y(x) = mx + c
Let x be the total minutes
y be the total steps
So, the rule becomes
y(x) = 40x + 0
⇒y = 40x
As she walks 40 steps in 1 minutes
So, rate of change will be 40 and constant term will be 0.
-21/7 , -2.7 , 21/9 , 2.27
least to greatest
To solve this we are going to use the half life equation
Where:
is the initial sample
is the time in years
is the half life of the substance
is the remainder quantity after
years
From the problem we know that:
Lets replace those values in our equation to find
:
We can conclude that after 1600 years of radioactive decay, the mass of the 100-gram sample will be
91.7 grams.
Hi
96 miles ⇒ 3.2 gallons
x miles ⇒ 12.5 gallons
3.2x = 96·(12.5)
3.2x = 1,200
x = 1,200/3.2
x = 12,000/32
x = 375 miles
or
96/3.2 = 960/32 = 30 miles/gallon
1 gallon ⇒ 30 miles
12.5 gallons ⇒ x miles
x = 30·(12.5)
x = 375 miles
Answer: 375 miles
