Answer:
2.86$
Step-by-step explanation:
first you must find out how much she is spending since she is buying 2.8 pounds of asparagus that are 2.55 per pound you can just times 2.8 x 2.55 its the same as if it were a dollar for a pound it would be 1 x 1 except in the case of this question it is a decimal number. Now that you know how much she spent you would subtract it from 10 since that's the amount she gave the cashier so you subtract the cost from how much she gave and you will get how much change she will get.
D. 30* Because This is definitely smaller than a 45 degree angle. If it was a bit wider it would be.
Answer:
y = 0.1(4^x)
Step-by-step explanation:
An exponential function can be written as ...
y = a(b^x)
where 'a' is the y-intercept, and 'b' is the ratio of terms with consecutive x-values.
The table tells us a=0.1, and b=0.4/0.1 = 4. The equation is ...
y = 0.1(4^x)
