PLS HELP ME!!!!! IT IS TIMED

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.

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

Answer:

Step-by-step explanation:

y=-1/13x   since it is perpendicular flip it and make it negative

Answer:

y = -1/13x + 27/13

Step-by-step explanation:

A perpendicular line will have the opposite reciprocal and sign.

So the perpendicular line slope to y = 13x + 4 would be -1/13

NOW PLUG IN (1, 2) TO GET THE Y- INTERCEPT

2 = -1/13(1) + b (b represents the y- intercept)

2 = -1/13 + b (add 1/13 to both sides)

y = -1/13x + 27/13 is the perpendicular line.

Hope this helps ya!!

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

rakka flakka told me

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:

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

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

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

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.

Answer:

B. The slope is -2, and the y-intercept is 12
