Write the equation of the line through the points (1, 3), (3, 3)

Answers

Answer:

y  = 3

Step-by-step explanation:

P ( 1 , 3)    and  Q ( 3 , 3 )

The straight line is parallel to the x-axis since the two points have the same y.

The intercept with the y-axis is 3.

The slope-point equation for a line is:

y  = m*x + b             (1)

m is the slope and  b is the intercept with the y-axis

To calculate the slope

m =  (  y₂ -  y₁ ) /  ( x₂  -  x₁ )

m =  3 - 3 / 3 - 1          m   = 0 / 2      m  = 0

therefore, equatio (1) becomes

y  =  0*x + 3

y  = 3

The radii of two right circular cylinders are in the ratio 3 : 4 and their heights are in the ratio 1 : 2. Calculate the ratio of their curved surface areas

Answers

Answer:

18.852:50.272

Step-by-step explanation:

Step one:

given

The radii of two right circular cylinders are in the ratio 3 : 4

r1= 3

r2= 4

Their heights are in the ratio 1 : 2

h1= 1

h2= 2

Step two:

The expression for the curve surface area is

CSA= 2πrh

CAS1=  2πr1h1

CAS1=  2*3.142*3*1

CAS1=  18.852

CAS2=  2πr2h2

CAS2=  2*3.142*4*2

CAS1=  50.272

The area of a square is 100cm what is the perimeter?

Answers

Answer:

your perimeter will be 40cm

The 4 sides of a square are the same length. Find the length of a side by taking the square root of the area.

Side = sqrt(100) = 10 cm

Perimeter = side length x 4

Perimeter = 10 x 4 = 40 cm

Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works. If the number of pizzas varies directly with minutes, how many pizzas can Allan make in 3 hours? Please Help

Answers

Answer:

96 pizzas

Step-by-step explanation:

Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works.

We are told that;

If the number of pizzas varies directly with minutes,

P ∝ M

P = kM

Hence:

8 = 15k

k = 8/15

How many pizzas can Allan make in 3 hours?

Convert 3 hours to minutes

1 hour = 60 minutes

3 hours = x

x = 3 × 60

x = 180 minutes

Hence,

M = 180 minutes

k = 8/15

P = kM

P = 8/15 × 180

P = 96 pizzas

Therefore, Allan can make 96 pizzas in 3 hours

Answers

Answer:

F=95

L=70

Step-by-step explanation:

3L+2F=400

2L+3F=425

Plug in and substitute

F=95

L=70

(Can I get brainliest please)

Answer:

lemon cookies = 70 calories

fudge cookies = 95 calories

Step-by-step explanation:

Lemon cookies = "x"

Fudge cookies = "y"

As per what is given;

3x + 2y = 400

2x + 3y = 425

Multiply the first equation by (-3), and the second by (2)

-9x - 6y = -1200

4x + 6y = 850

________________

-5x = - 350

Inverse operations;

-5x = -350

/-5      /-5

x = 70

Subsitute back in;

3x + 2y = 400

3(70) + 2y = 400

Simplify, inverse operations;

210 + 2y = 400

-210           -210

2y = 190

y = 95

Solve the proportion what y = ?

Answers

Answer:

y = 12

Step-by-step explanation:

proportions can be solved by cross-multiplying

to work with smaller numbers, you can simplify [tex]\frac{14}{10}[/tex] to be [tex]\frac{7}{5}[/tex]

[tex]\frac{7}{5}[/tex] = [tex]\frac{y+9}{15}[/tex]

7(15) = 5(y + 9)

105 = 5y + 45

60 = 5y

y = 12

Triangle QRS is reflected over y = 2. What are the coordinates of Q'?

Answers

Answer:

(1,6)

Step-by-step explanation:

In order to reflect a point over a horizontal line, you need to count how many units it takes to reach that line (going vertically). Once you have that number, count that many units starting from that point on the line (again, going vertically), then that is your reflected point.

Counting from point Q to the line y = 2, it takes 4 units. So starting from that point on the line where I left off, I would count another 4 units, taking me to (1,6). The picture below explains it better visually.

It takes meagen 56 minutes to cook a golden turkey that weighs 12 pounds. Her compieter, chef Geraidine takes 1 hour and 16 minutes to cook a golden turkey that weighs 304 ounces. What is the differnece in pounds cooking the golden turkey er minute between chef meagen and chef chef geraidine?

Answers

Answer:

0.033 pounds/min

Step-by-step explanation:

For Meagen:

Time taken to cook golden turkey = 56 minutes

Weight of golden turkey = 12 pounds

For her competitor:

Time taken to cook golden turkey = 1 hour 16 minutes = 77 minutes

Weight of golden turkey = 304 ounces

16 ounces = 1 pound

Therefore, 304 ounces = [tex]\frac{304}{16}[/tex] = 19 pounds

Now, let us find the number of pounds cooked per minute by each chef.

Pounds cooked per minute by Meagen = [tex]\frac{12}{56} = 0.214\ pounds/min[/tex]

Pounds cooked per minute by the competitor = [tex]\frac{19}{77} = 0.247\ pounds/min[/tex]

Difference = 0.247 - 0.214 = 0.033 pounds/min

Which graph represents the solution to the system of inequalities below?
5x - 4y > 4
x + y < 2

Answers

Answer:

The correct option is;

B

Step-by-step explanation:

The given system of inequalities are;

5·x - 4·y > 4...(1)

x + y < 2...(2)

Representing both inequalities as a function of "y", gives;

For, 5·x - 4·y > 4...(1), we have;

-4·y > 4 - 5·x

y < 4/(-4) - 5·x/(-4)

∴ y < 5·x/4 - 1

For x + y < 2...(2), we have;

y < 2 - x

Therefore, y is less than the values given by the equation of the straight line equalities, and the feasible region is given by the common region under both dashed lines representing both inequalities as shown in the attached diagram created using Microsoft Excel

The correct option is therefore, B.
