I need to know what is 140% of 15

Answers

Answer 1

Answer: Something percent of a number is itself*something/100

For instance, 50% of 10 is 10*50/100=10/2=5

Here, $15*(140)/(100)=21$

Answer 2

Answer:

Final answer:

140% of 15 is calculated by converting the percentage to a decimal (1.4) and then multiplying it by 15, giving a result of 21.

Explanation:

To determine 140% of 15, the process involves converting the percentage to a decimal and multiplying it by the given number. In the first step, 140% is transformed into 1.4 by dividing it by 100. Next, 15 is multiplied by 1.4. Executing this multiplication yields a final result of 21. The calculation follows a two-step procedure: conversion to a decimal and multiplication. This method ensures accurate determination of the desired percentage. In this case, the outcome of 140% of 15 is precisely 21, showcasing the systematic approach used in the mathematical computation.

Given the equation 4x + 2y = 9, which equation below would cause an inconsistent-independent system?A:6x + 12y = 13
B: 2x + y = -6
C:x - 2y = 7
D:8x - 4y = -5

Answers

Inconsistent-independent system means that there are no solutions.
Graphically the lines of those equations will never cross - the lines are parallel.

So when the two lines are parallel?
When they have the same A factors.

So when you have an equation 4x+2y=9 we need to rewrite it to
y= -2x+9/2
So the A factor is -2 (it is the number with x) and the B factor is 9/2

So all we need to do now is to find an equation with the same A factor.

Lets rewrite equations in answers:
A: 6x+12y=13 -> y=-1/2x+13/12 A=-1/2 - so it is not an equation we are looking for
B: 2x+y=-6 -> y=-2x-6 A=-2 - this is an equation we were looking for.
C: x-2y=7 -> y=1/2x-7/2 A=1/2 - so it is also not a good answer

The answer is B: the equation 2x+y=-6 will cause the inconsistent-independent system with the given equation.

A hybrid car can travel 40 miles per gallon. Approximately how many gallons of fuel will the car need to travel 20 km? (5 points) [1 mile = 1.6 km]

Answers

Answer:

To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.

Step-by-step explanation:

Proportions

The hybrid car can travel 40 miles per gallon.

Since one mile is equivalent to 1.6 Km, the distance traveled per gallon is 40*1.6 = 64 Km.

Now the distance is expressed in Km, we can find the gallons needed to travel 20 Km, by calculating 20/64 = 0.3125.

To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.

The school that Brenda goes to is selling tickets to the annual talent show. On the first day of the ticket sales the school sold 2 adult tickets and 14 child tickets for a total of $96. The school took in $120 on the second day by selling 12 adult tickets and 8 child tickets. find the price of an adult ticket and the price of a child ticket.

Answers

a=cost er adult ticket
c=cost per child ticket

2a+14c=96
12a+8c=120

solve

simplify by dividing firs equation by 2 and 2nd by 4

a+7c=48
3a+2c=30

multiply first equaiton by -3 and add to second
-3a-21c=-144
3a+2c=30 +
0a-19c=-114

-19c=-114
divide both sides by -19
x=6

sub back

a+7c=48
6+7c=48
minus 6
7c=42
divide 7
c=6

adult ticket=$6
child ticekt=$6

5.
aritmetic is same increase per term
14 to 21 is 7
21 to 42 is 21
7≠21
no

6.
decreases by 4 each time
an=a1+d(n-1)
an=10-4(n-1)
n=12 for 12th term
a12=10-4(12-1)
a12=10-4(11)
a12=10-44
a12=-34

it is -34

7.
missing term is y
22+n=y
y+n=34
22+n+n=34
22+2n=34
minus 22 from both sides
2n=12
divide both sides by 2
n=6
22+n=y
22+6=y
28=y
