Answer:
$ 1.9125
Step-by-step explanation:
price of gas last week= $2.25
15% of $2.25 = 15/100 × 2.25
= $0.3375
since the price of the gas decreased by 15% this week, the new price will be 2.25- 0.3373 =$1.9125.

Step-by-step explanation:
by what percent will a fraction increase if its numorator is increased by 60% and ist denominator decreased by 20%
Answer:
100%
Step-by-step explanation:
Assume the fraction is X/Y.
Increase the numerator by 60%: 1.6X
Decrease the denominator by 20%: 0.8Y
New value: 1.6X/0.8Y
That is equal to 2(X/Y)
The fraction increases by 100% [X/Y to s(X/Y)]

Answer:
The answer is 80°
Step-by-step explanation:
Given;We are given a hexagon with 6 anglesTo Find;The value of xHere, we know that the sum of all interior angles of hexagon is equal to 720°
So,
x + x + 140 + 140 + 140 + 140 = 720
2x + 560 = 720
2x + 560 – 560 = 720 – 560
2x = 160
2x/2 = 160/2
x = 80°
Thus, The value of x is 80°
For Verification
x + x + 140 + 140 + 140 + 140 = 720
80 + 80 + 140 + 140 + 140 + 140 = 720
720 = 720
L.H.S = R.H.S
Hence Verified!

A circle is drawn on the coordinate plane. It
has a center at (2, 1) and passes through the
point (2, 5). What is the approximate
circumference of the circle?
Step-by-step explanation:
please mark me as brainlist please
Answer:
Using Pythagorean theorem we can find the radius which is the distance between the center and any point along the circle:
r=((5-1)^2+(2-2)^2)^(1/2)
r=(4^2-0^2)^(1/2)
r=4 units.
Circumference=2pr so our circumference is 8p units^2
so about 25.13 u^2

11/12-3/4
a: 1/7
b: 1/5
c: 1/6
Answer: c. 1/6
Step-by-step explanation:
The least common demoninator would be 12, as 12 is a multiple of 4.
We can multiply the fraction 3/4 by (3/3)
3/4 = 3/4*(3/3)
= (3*3)/3*4)
= 9/12
We can plug in the value of 9/12 in as 3/4 back into the expression:
= 11/12 - 9/12
We can combine the numerators since there is a common denominator:
= (11-9)/12
= 2/12
Divide the numerator and denominator of this fraction by 2:

Out of a sample of 1,450 people, 1,000 said they prefer to drive themselves to work rather than carpool. Construct a 95% confidence interval for the population mean of people who would rather drive themselves than carpool.
CI = (65.84%, 72.09%)
CI = (66.58%, 71.35%)
CI = (65.27%, 72. 13%)
CI = (66.97%, 70.96%)
The required confidence interval for the population mean is; B: CI = (66.58%, 71.35%)
What is the Confidence Interval?We are given;
Sample size; n = 1450
Sample number; x = 1000
Thus,sample proportion is;
p^ = x/n = 1000/1450
p^ = 0.69
We are not given the population proportion but we will assume; p = 0.5
Formula for confidence interval is;
CI = p^ ± z√(p(1 - p)/n)
Where z for CL of 95% is; z = 1.96
Thus;
CI = 0.69 ± 1.96√(0.5(1 - 0.5)/1450)
CI = 0.69 ± 0.026
CI = (66.58%, 71.35%)

Answer: A'(3,0), B'(3,6), C'(9, 3)
Step-by-step explanation:
At a restaurant, 600 customers were served during a 10-hour period of time. Which graph has a slope that best represents the number of customers that were served per hour at this restaurant?
The number of customers that were served per hour at this restaurant is 60 customers per hour
What is a linear equation?A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
600 customers were served during a 10-hour period of time. Hence:
slope = 600 customers / 10 hours = 60 customers per hour.
The number of customers that were served per hour at this restaurant is 60 customers per hour

Answer:
106
Step-by-step explanation:
The given is a pentagon and the sum of interior angles is = 540
so to find the value of x:
132 + 90 + x + x + x = 540 add like terms
222 + 3x = 540 subtract 222 from both sides
3x = 318 divide both sides by 3
x = 106

Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
3(x + 2) + 52 + 35 = 180 , that is
3(x + 2) + 87 = 180 ( subtract 87 from both sides )
3(x + 2) = 93 ( divide both sides by 3 )
x + 2 = 31 ( subtract 2 from both sides )
x = 29

Trains Two trains, Train A and Train B, weigh a total of 281 tons. Train A is heavier than Train B. The difference of their weights is 113 tons. What is the weight of each train? Train A weighs tons.
Answer:
A = 197 tons
B = 84 tons
Step-by-step explanation:
Given Equations: A + B = 281 A - B = 113
A = 113 + B
113 + B + B = 281
2B = 281 - 113
2B = 168
B = 84
A = 113 + 84
A = 197
