Answer 1

Answer:

Bill and Ted are going to order t-shirts for there school clubs. The t-shirts will have the club logo printed on the front. Bill and Ted ask two local t-shirt companies to give them a price. * Patty's Printing charges $21.50 for each t-shirt. * Sandra's shirts has a one-time set up fee for $63 and then charges $18 for each t-sh

Step-by-step explanation:

Part 2: Table Chart:

Number of t-shirts: 2

Patty's cost: 43$

Sandra's cost: : 99$

Number of t-shirts: 4

Patty's cost: 86$

Sandra's cost: : 135$

Number of t-shirts: 6

Patty's cost: 129$

Sandra's cost: : 171$

Number of t-shirts: 8

Patty's cost: 172$

Sandra's cost: : 207$

Number of t-shirts: 10

Patty's cost: 215$

Sandra's cost: : 243$

Number of t-shirts: 12

Patty's cost: 258$

Sandra's cost: : 279$

Number of t-shirts: 14

Patty's cost: 301$

Sandra's cost: : 315$

Number of t-shirts: 16

Patty's cost: 344$

Sandra's cost: : 351$

Number of t-shirts: 18

Patty's cost: 387$

Sandra's cost: : 387$

Part 3: Patty's Printing

Linear equation = equation of a line= y=mx+b

y=21.5x

Part 4: Sandra's Shirts:

Linear equation = equation of a line= y=mx+b

y= 18x+63

Part 5: Note to Jackie

Dear Jackie, I recommend Sandra's shirts.

Write equations:

Sandra's Shirts = 18x+63

Patty's Printing = 21.5x

Sandra's Shirts: 495=18x+63 = 24 shirts

Patty's Printing: 495=21.5x = 23 shirts

Part 6: Refute Jackie

Sandra's Shirts is more expensive at the beginning, but as you buy more shirts (greater than 18), Patty's Printing becomes cheaper.

You should probably add to this, but I can't think of anything else.

Part 7: Equality

At 18 shirts (see table), the shirt cost is equal.

You should probably add to this, but I can't think of anything else.

18x+63=21.5x

Words of encouragement:

Good luck!

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)

Answers

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Step-by-step explanation:

The tens place value would help you write 50/1,000 as 5/100 because to get 50 to 5, you would need to get rid of the tens place. In other words, you would need to divide by 10.

50 divided by 10 is 5

1,000 divided by 10 is 100

The correct answer would be the tenths place.

-----------------------

3y = 63

÷3     ÷3

--------------

y = 21

x + 27 + 3y + 8x + 18 = 180

9x + 45 + 3(21) = 180

Write an equation in standard form of the line that passes through (−6,−10) and has the slope m=1/6.

Answers

Step-by-step explanation:

y-b=m(x-a)

y--10=1/6(x--6)

y+10=1/6(x+6)

6y+60=1(x+6)

6y+60=1x+6

6y=1x-54

y=1/6x-54/6

y=1/6x-9

The  equation of line is y= 1/6x - 9.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

slope= 1/6

and, passes through (−6,−10)

Now, using slope intercept form

y- a =m (x- b)

y - (-10)= 1/6(x -(-6))

y + 10= 1/6( x + 6)

y + 10 = 1/6x + 1

y= 1/6x - 9

Hence, the equation of line is y= 1/6x - 9.

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!

Answers

The function for the points are  y = -15x - 5

How to determine the function

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

m is the slope of the liney - y₁ and (x - x₁) are the points

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

1. y = -3/4 +4 cause that is the same line as the equation and since they are the same line it would mean there would be infinitely many solutions.

2. y=-3/4x+2 if you graph this line next to the orginal line it runs through (0,1) and you can see that its paralellel and will never meet the other line so there will be no solutions

3. for this question im confused because none of the answers fits the line that the question is asking for the closest would be y= -3/4x+2 since it runs through (0,2) but other than that none of the answers fit the line its describing.

Answer: conversion factor is just how much of it is in another unit

Step-by-step explanation:

for example, 5280 feet are in a mile so the original rate of 15 in a hour can be turned into the equation on the first image.


Original rate (15 miles) x conversion factor (5280 feet are in a mile)

So when you multiple get 79,200 which simple means, in one hour she will go 79,200 ft. This concept can be applied to other scenarios such as feet and meter, liters and gallons, miles and kilometers, all that’s necessary is to know the conversion rate. The conversion factor is simple how much of your term is in another, this may be confusing but imagine it like this how many feet are in a yard? The answer is 3 so the conversion factor is just 3ft:1yd

The answer is 3 but the conversion factor is 3ft 1 yard

The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?

160 ml
400 ml
1,600 ml
4,000 ml

Answers

Answer: 1,600 ml

Step-by-step explanation:

You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).

2,800 ml - 1,200 ml = 1,600 ml

I hope this helps :)

Answer: 1,600 mL

Step-by-step explanation:

1. convert the 1,200 mL to L, which is 1.2 L.

2. Subtract that value from 2.8 L, equaling 1.6 L

3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.

Answer:

It is point c

Step-by-step explanation:

ok so the coordinates are always (x,y) so therefore if X is 0 then it stays in the middle of the graph and doesn't go anywhere. since Y is -3, y always goes down or up. so if it goes down then it is negative. up is always positive. same with x. X is always horizontal so if it moves right, it is positive and left (backwards) is negative. hope this helps and isn't confusing. *Also, since it's -3, then it goes down negative 3 units. *

Answer:

C

Step-by-step explanation:

In the coordinate (x,y), x refers to the place of point above the horizontal line while y represents the place of point in the side to its vertical lines.

Here, x is 0, that means it is lying on y line and y is -3, that means it's lying in 3rd quadrant. So, point C matches them completely. That's why the correct answer is C.

Step-by-step explanation:

A = 40 + .1(M-500) for M>500

B = 25 + .05M

20 minutes a day for 30 days = 600 minutes per month

A(600) = 40+.1(100) = $50

B(600) = 25 + .05(100) = $30

Plan B is less expensive

40+.1(M-500)= 25+.05M

40-25- .1(500) = .05-.1M

.05M = 35
M= 35/.05 = 700 minutes will have the same cost under plan A or B

40+.1(200) = $60 under plan A
25+.05(700) = $60 under plan B

Answers

Answer: Option A is the correct answer

Step-by-step explanation: I took the test and got it right

The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.

Given approximate weights of the two animals are as:

1. 5.12 x 10² lbs

2. 6.8 x 10² lbs

We need to find the total weight of the two animals.

Step 1: Add the weights together:

5.12 x 10² lbs + 6.8 x 10² lbs

Step 2: Perform the addition:

(5.12 + 6.8) x 10² lbs

11.92 x 10² lbs

Step 3: Express the result in scientific notation with the correct number of significant digits:

The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:

11.9 x 10² lbs

This matches option 2 from your provided answers:

2. 1.19 x 10³ lbs.

So, the correct answer is: 1.19 x 10³ lbs.
