it's should be 220 because your starting point is at 70 then add 15 for 10 weeks which means you have to add 15*10 or 150 to 70 which will give you 220
Area of triangle
= h*b/2
x*7/2=17.5
17.5*2/7
=5m
Height=5m
Answer:
This shows us that there are 1400 readers.
Step-by-step explanation:
To work this out you would first need to find how many times 5% goes into 100%, You can do this by dividing 100 by 5, this gives you 20. This is because the whole amount is equivalent to 100%.
To work out the total number of readers you would multiply 70 by 20, this gives you 1400. This is because we know that 70 is equivalent to 5% and that 5% goes into 100% 20. So by multiplying 70 by 20 we are working out the total (100%), and that this shows us there are 1400 readers.
1) Divide 100 by 5.
2) Multiply 70 by 20.
Answer:
y = 2x + 150
Step-by-step explanation:
The initial value is $150, this is the y intercept as this is the amount she has at day 0.
To calculate the gradient use change in Y/change in X. the question says that there is an increase of $2 each day so the gradient is 2.
Since y = mx + c we can replace m and c for 2 and 150 to get y = 2x + 150
The answer is -2 4/5. This is in simplest form because my calculator does everything into simplest form.
