Answer is $23.76

Calculate 20% of 22 and add it to 22:

20% x 22 = 4.4

22 + 4.4 = $26.4

Calculate 10% of 26.4 and subtract from 26.4

10% x 26.4 = 2.64

26.4 - 2.64 = $23.76

a traveling salesman drives his car 30000 miles a year. His car travels 16 miles to the gallon of gas. How many gallons of gas d
DENIUS [597]

Answer:

187.5 gallons

Step-by-step explanation:

Make a proportion

\frac{16 miles}{1 gallon} = \frac{3000 miles}{x}

3000/16 = 187.5, so multiply 1 by 187.5 to find the gallons used in a year

This gets you 187.5 gallons used in a year

Given the explicit rule, f(n) = 2n - 3, generate the first four terms in the sequence.
Vikki [24]

Answer: -1, 1, 3, 5

Step-by-step explanation:

F(n)= 2n-3

F(1)=2(1)-3= -1

F(2)=2(2)-3= 1

F(3)=2(3)-3= 3

F(4)=2(4)-3=5

The region R enclosed between the graph of the function y=x^2−4x+5 and the x-axis for 0≤x≤4 is partitioned into four subinterval
Marina CMI [18]

Answer:

9.00 square units

Step-by-step explanation:

The width of the interval is 4 − 0 = 4.  Divided by 4 equal subintervals, the width of each subinterval is 4/4 = 1.

The subintervals are:

0 ≤ x ≤ 1

1 ≤ x ≤ 2

2 ≤ x ≤ 3

3 ≤ x ≤ 4

MRAM is midpoint rectangular approximation method.  So we use the midpoints of each interval to find the height of the rectangle:

f(0.5) = (0.5)² − 4(0.5) + 5 = 3.25

f(1.5) = (1.5)² − 4(1.5) + 5 = 1.25

f(2.5) = (2.5)² − 4(2.5) + 5 = 1.25

f(3.5) = (3.5)² − 4(3.5) + 5 = 3.25

So the total approximate area is:

A = 3.25 + 1.25 + 1.25 + 3.25

A = 9.00
