2. Gerald was given the following problem to solve for the length of the “?”. He has made a mistake in his work. Identify and describe how he made his mistake. Then, solve the problem correctly.
Answer:
x = 18.7
Step-by-step explanation:
Gerald's answer is almost correct.
He just needs to switch the 14 and the x.
it should be
24/x = 18/14
solve for x by cross multiplication
18x = (24)(14)
18x = 336
x = 18.7
You treat your friend to lunch. The food bill was $30.24. A 7% sales tax will be added and you want to leave a 20% tip.
a. Find the sales tax.
b. Find the tip.
c. Find the total amount you pay for lunch.
Answer:
a. $2.12
b. $6.45
c. $38.81
Step-by-step explanation:
a.
I'll convert 30.24 and 7% into fractions.
756/25 * 7/100
Cross cancel 756 and 100 (GCF is 4)
189/25 * 7/25
Convert above into a single fraction
(189 * 7)/(25 * 25)
Multiply 189 by 7, then 25 by 25.
1323/625
Divide, then round to the nearest cent
$2.1168 ≈ $2.12 in sales tax
b.
Like before, I'll convert $32.26 ($30.24 + $2.12) and 20% into fractions.
1613/50 * 1/5
Multiply 50 by 5.
1613/250
Divide, then round to the nearest cent.
$6.452 ≈ $6.45 in tip money
c.
This is probably the simplest part of the 3. Just add $30.24 + $2.12 + $6.45.
$30.24 + $2.12 + $6.45
$32.36 + $6.45
You pay a total of $38.81 for lunch.

Henry buys a softball for $16 plus a 9% tax. Ella buys a pair of shoes for $17 plus a 9% tax. Enter the difference in the amount
Henry and Ella paid, including tax. Round your answer to the nearest cent.
Answer:
The different of the tax was 0.09 cents
Step-by-step explanation:
1. Find how much the tax was
Henry = (16/100) (9) = (0.16) (9) = $1.44
Ella = (17/100) (9) = (0.17) (9) = $1.53
2. Subtract the taxes
1.53 - 1.44 = 0.09 cent

asking for the equation
Which is an equation of the line that passes through the points (-6, 3) and (2, 7)?
Answer:
slope: 1/2
y: intercept: (0;6)
so B
The equation of the line is y = x/2 + 6 which passes through the points (-6, 3) and (2, 7) option (B) is correct.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
The line that passes through the points (-6, 3) and (2, 7)
The equation of the line:
y - 7 = (7 - 3)/(2 + 6)[x - 2]
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
y = (1/2)x - 1 + 7
y = x/2 + 6
Thus, the equation of the line is y = x/2 + 6 which passes through the points (-6, 3) and (2, 7) option (B) is correct.

Identify the zeros of the quadratic function.
x=1 and x= -3
x= -1 and x=3
y= -1 and y= -3
y= -1 and y=3
Answer:
The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

For the function in Item 2, what is
the average rate of change over
the interval 2 ≤ x ≤ 3?
A.(0)
B.(1)
C.(5)
D.(25)
Answer:
See below.
Step-by-step explanation:
You don't show what the function is, but I'll explain how to do it.
The average rate of change of function f(x), from x = a to x = b, is given by the fraction:
[tex] \dfrac{f(b) - f(a)}{b - a} [/tex]
Since I don't know what the function is, I cannot evaluate the function at x = a and at x = b, which in your case are x = 2 and x = 3, but you can do it.
Here are the steps you need to do:
1) Evaluate the function at x = 3. Get a value for f(3).
2) Evaluate the function at x = 2. Get a value for f(2).
3) Evaluate the following fraction, after writing the values for f(3) and f(2) that you found in steps 1) and 2) above.
[tex] \dfrac{f(3) - f(2)}{3 - 2} [/tex]
The denominator above is easy. It's just 1.
Try it and see what you get. You can write the function and your answer in the comments if you need more help.
What is the quotient of 2/3/4 ÷ 1/4
Answer:
11
Step-by-step explanation:
Do kcf (keep,change,flip)
First, covert 2 3/4 into an improper fraction
Then after you do that you get 11/4
so you do the equation 11/4 ÷ 1/4
when you do kcf it would be 11/4 × 4/1=
11/4×4/1=44/4 simplify divide both by 4 = 11

Please Help WORTH 15 POINTS Highlighted one is wrong
Answer:
change in buyer tastes.
Step-by-step explanation:
Buyers now want more donuts than the other goods.
increase in the cost of donuts is more likely to decrease the amount of donuts consumed, as they would be more expensive
consumers expecting something doesn't necessarily change anything, as they haven't yet dropped and therefore it's unlikely they'd increase the demand until they actually were cheaper.
Coffee doesn't necessarily effect donut sales, unless stated in the question.

Answer:
a) 46° b) 66° c) 4 cm
Step-by-step explanation:
a) because it is isosceles triangle, therefore, 2 opposite angles, and angle sum of triangle is 180 so 180-67-67=46
b) because again, isosceles triangle so two opposite sides,
x+x+48=180
2x=132
x=66
c)because it is equilateral, so therefore all angles are 60 degrees and all sides equal.
