Sarah wants to leave a tip of 15%. Her bill before the tip is $23.00. How much should she leave for the tip ? show your work.
Answer:
$26.45.
Step-by-step explanation:
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $23.00 meal cost is.This is always done by multiplying 0.15 by $23.00, or
0.15 x $23.00=$3.45.
So, the amount of tip you are going to leave is $3.45.
This makes the total cost of your meal (to write on your charge slip or other payment)
$23.00 + $3.45 = $26.45.

What is the slope of a line that is perpendicular to the line whose equation is 8y−5x=11?
Ill give someone brainlist
9514 1404 393
Answer:
-8/5
Step-by-step explanation:
When you solve for y, the slope of the line is the x-coefficient. For the given line, that is ...
8y = 5x +11 . . . . . add 5x
y = 5/8x +11/8 . . . . divide by 8
The given line has a slope of 5/8. The perpendicular line will have a slope that is the opposite of the reciprocal of this:
-1/(5/8) = -8/5 . . . . slope of perpendicular line
Answer:
The slope of the perpendicular line will be -8/5, or -1.6
Step-by-step explanation:
First we need to rearrange the equation to show the slope, putting in the format y = sx + c:
[tex]8y - 5x = 11\\8y = 5x + 11\\y = \frac{5}{8}x + \frac{11}{8}[/tex]
So the given line has a slope of 5/8.
A line perpendicular to that will have a negative reciprocal of that slope, so it's slope will be -8/5.
solve this plz
z = 2a + 2. for a
Answer:
a=(z-2)/2
Step-by-step explanation:
You need to isolate your "a" variable so first you want to subtract 2 from both sides, leaving you with:
z-2=2a
then you want to divide by 2 on both sides to isolate your "a" variable which would leave you with
a=[tex]\frac{(z-2)}{2}[/tex]

Answer:
Yes good job!
Step-by-step explanation:
If f(x) = 3x + 2, what is f(5)?
Answer:
17
Step-by-step explanation:
f(x) is the same as y=. "What is f(5)" is the same as saying what is y=3x + 2 when x is 5.
Either way, you are going to replace x with is numerical value, which is 5, and then solve.
y = 3(5) + 2
y = 15 +2
y = 17
f(5) = 17

Sydney has a bag of stuffed animals containing, 1 elephant, 4 bears, 3 cats, and 2 dogs. If she randomly selects 1 stuffed animal from the bag, places it on her bed and then selects another animal. What is the probability that she chooses a bear both times?
Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15
What is the slope of the line and y intercept PLEASE HELP
Answer:
c. slope: -3/2, y-intercept: 1/2
Step-by-step explanation:
First, let's find out the y-intercept. The y-intercept is where the line crosses the y-axis (the vertical line). In this question, the line crosses the y-axis at 1/2, so that is the y-intercept.
Now, we'll find the slope. The first thing we can do is look for two simple points on the graph. The points I'm going to use are (3, -4) and (1, -1). Slope is written rise over run. If you look at the point (3, -4) and rise (go up/down) 3 (up) and run (go across) -2 (left), you will reach the point (1, -1).
So the slope is -3/2 and the y-intercept is 1/2, which is in answer c.
I hope this helps you out, and have an amazing day (｡･v･)ﾉﾞ
A city has a vacant lot in the shape of an isosceles trapezoid and the city workers are installing a fence around the lot. What length of fencing is required? Round the answer to the nearest meter. А 25 m B x 25 m 45° The length of fencing required is meters.
Answer:
Length of the fence required = 135 m
Step-by-step explanation:
Total length of the fence required to cover the vacant lot = Perimeter of the isosceles trapezoid
Perimeter of ABCD = AB + BC + CD + AD
Since, AB = BC = EF = ED = 25 m
From the given right triangle BEC,
m∠EBC = m∠ECB = 45°
ΔBEC will be an isosceles triangle.
So, BE = EC
By Pythagoras theorem,
BC² = BE² + EC²
25² = 2(EC)²
EC = [tex]\frac{25}{\sqrt{2}} =17.7[/tex] m
And DC = (DF + EF + EC)
= EC + EF + EC [Since, DF = EC]
= 2EC + EF
= 35.4 + 25
= 60.4 m
Hence. perimeter of ABCD = 25 + 25 + 60.4 + 25
= 135.4 m
≈ 135 m
Therefore, length of the fence required = 132 m

Question 5
Trent has 12 cups of ice cream for his daughter's birthday party
If each serving is
3/4
of a cup, how many children can eat ice cream?
А
1
B
9
С
12
D
16
Answer:
B. 9
Step-by-step explanation:
12 times 3/4 is 9
Answer:
it takes 4 of the 3/4 servings to make a whole number and it's 3 cups.
12/3= 4 and 4*4= 16
so 16 children can eat ice cream
or you could do 12/0.75= 16
you would do that because 3/4=0.75
you would divide and not multiply because you're seeing how many times 0.75 can go into 12
