Answer:
16%
Step-by-step explanation:
To find the percent, add the total for each meal to find the total dollars spent.
23.59 + 40.65 + 30.50 + 15.68 = 110.42
Divide the tip amount 17.67 by 110.42.
17.67/110.42 = 0.16
Multiply the decimal by 100 to convert to a percent.
0.16*100 = 16%
Answer:
x = 3; y = 2
Step-by-step explanation:
x + y = 5
y = 2x - 4
<em>Isolate the y in the first equation</em>
y = 5 - x
y = 2x - 4
<em>Substitute the values</em>
5 - x = 2x - 4
<em>Isolate the Variable</em>
9 = 3x
<em>Simplify</em>
3 = x
<em>Plug that into the first equation</em>
3 + y = 5
<em>Subtract 3 from both sides</em>
y = 2
Answer:
Step-by-step explanation:
In this question, it is given that, A rectangle with a short side of 6. An arrow points to a smaller rectangle with a short side of 1.5 .
The shorter side of first rectangle is of measurement 6 units and of second rectangle, is of size 1.5units .
To find the scale factor, we have to do division of the shorter sides of the first and second rectangle, that is
So the scale factor is 0.25 .
There is a way to do this algebraically using equations, but it is really messy so I am going to go over the way to do it. The way you do this is by finding whole numbers that multiply to make -192. Start with 1 and 192, 2 and 96, 3 and 64, etc and make the smaller number negative.
The reason why you make the smaller number negative is because we are looking for what numbers add together to make a positive number (10). If the bigger number was negative, then we would get a negative sum.
From what i could find, there aren't any whole numbers that satisfy this, and i doubt that the question would want you to find decimals for this.
The way to find this with equations (in short) is to have to variables, x and y, and make two equations. in this case x+y=10 and xy=-192. Solve one equation for a variable and then use substitution to plug that variable into the other equation. if you do this you get really long decimals.
The answer is false, they are parallel not perpendicular
