Q1) 3 cups to milliliters. Round to the nearest hundredth if necessary. Your answer​

Answers

Answer:

3 cups = 709.77 milliliters

Step-by-step explanation:

Cup : milliliters

1 cup : 236.59 milliliters

3 cups : x milliliters

Equate both ratios

1 / 236.59 = 3 / x

Cross product

1 * x = 236.59 * 3

x = 709.77 milliliters

Therefore,

A bowling alley charges $2.50 per game plus $4 to rent shoes. A second bowling alley charges $4 per game plus $1 to rent shoes. How many games would a
person have to play for the two bowling alleys to cost the same amount?

Answers

Answer:

The person would have to play 2 games for the two bowling alleys to cost the same amount

Step-by-step explanation:

Assume that the number of games that makes the two costs equal is x

∵ A bowling alley charges $2.50 per game plus $4 to rent shoes

∵ The number of games is x

The cost = 2.50x + 4

∵ A second bowling alley charges $4 per game plus $1 to rent shoes

∵ The number of games is x

The cost = 4x + 1

∵ They have the same cost

→ Equate the 2 expressions above

4x + 1 = 2.50x + 4

→ Subtract 2.50x from both sides

∵ 4x - 2.50x + 1 = 2.50x - 2.50x + 4

1.50x + 1 = 4

→ Subtract 1 from both sides

∵ 1.50x + 1 - 1 = 4 - 1

1.50x = 3

→ Divide both sides by 1.50

x = 2

The person would have to play 2 games for the two bowling alleys to

   cost the same amount

Bob’s monthly phone bill is made up of a $10 fee plus $0.05 per minute. Bob’s phone bill for July was $22. Write an equation to model the situation using m to represent the number of minutes. Solve the equation to determine the number of phone minutes Bob used in July.

Answers

Answer:

equation: 10 + 0.05x=22

Step-by-step explanation:

the next step after writing the equation would be to subtract 10 from both sides to get 0.05x=12. after this you would then have to divide 12 by 0.05 to get 240 minutes. you could check it by putting 240 in for x to get 10+0.05(240)=22. you would then multiply 0.05 by 240 to get 12 and then add 10 onto it to get 22 which was already given.

9514 1404 393

Answer:

  equation: 10 +0.05m = 22

  solution: Bob used 240 minutes in July

Step-by-step explanation:

Bob's bill is the total of the fixed fee and the charges based on minutes. The latter is 0.05m, where m is the number of minutes. Hence, Bob's July bill is ...

 10 + 0.05m = 22 . . . . . total of charges for July is $22

__

The equation is solved by subtracting the constant and dividing by the coefficient of m.

  0.05m = 12 . . . . . subtract 10

  m = 12/0.05 = 240

Bob used 240 minutes in July.

The system of equations representing the rates for two duplicating companies are -

C[1] = 5 + 0.06x

C[2] = 10 + 0.04x

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have the rates for two duplicating companies. There are two different rates as-

[1] > initial fee of $5 and $0.06 per page.

[2] > initial fee of $10.00 and $0.04 per page.

For the [1] company, we can write the equation as -

C[1] = 5 + 0.06x

For the [2] company, we can write the equation as -

C[2] = 10 + 0.04x

So, the system of equations will be -

C[1] = 5 + 0.06x

C[2] = 10 + 0.04x

Therefore, the system of equations representing the rates for two duplicating companies are -

C[1] = 5 + 0.06x

C[2] = 10 + 0.04x

Jen and Kamlee are walking to school. After 20 minutes, Jen has walked 45 mile. After 25 minutes, Kamlee has walked 56 mile. Find their speeds in miles per hour. Enter the correct answers in the boxes.

Answers

Answer:

Jen's speed = 135 miles per hour (Approx)

Kamlee's speed = 134 miles per hour (Approx)

Step-by-step explanation:

Given:

Jen walk = 45 miles

Jen's time = 20 min = 20/60 = 0.333 hour

Kamlee walk = 56 miles

Kamlee's time = 25 min = 25/60 = 0.416667 hour

Find:

Speed

Computation:

Jen's speed = 45 / 0.333

Jen's speed = 135 miles per hour (Approx)

Kamlee's speed = 56 / 0.416667

Kamlee's speed = 134 miles per hour (Approx)

Answers

Answer: y=-4x+5

Step-by-step explanation:

Answer:

y=-4x+5

Step-by-step explanation:

1. Find the slope by counting downward and over from one point to another point.  Let's start from (-2,13) and go down to (0,5)

If you are worried about miscounting, you could also use the slope formula which is y2-y1/x2-x1

5-13/0--2

= -8/2

The slope is -4.

2. FInd where the line crosses the y-axis to get the y-intercept. Here it crosses it at 5.

The next event requires each runner to jump 8 hurdles that are spaced 12.3 meters apart. If there are 15 meters from the starting line to the first hurdle and 10.5 meters from the last hurdle to the finish line, how long is the race? Show your work. (2 points) 15 m 10.5 m Start Finish

Answers

Answer: 111.6 meters

Step-by-step explanation:

Since there are 8 hurdles that are spaced 12.3 meters apart, the number of meters here will be:

= 7 × 12.3 meters

= 86.1 meters

We are further told that there are 15 meters from the starting line to the first hurdle and 10.5 meters from the last hurdle to the finish line.

The length of the race will be:

= 86.1 + 15 + 10.5

= 111.6 meters

Answer:

The race is 111.6 m long.

8 hurdles spaced 12.3 m apart means 7 spaces that are 12.3 m in length; 7*12.3 = 86.1

Add to this the distance to the first hurdle and the distance from the last hurdle:

86.1+15+10.5 = 111.6 m

Algebra I

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

2r + 8s = -4

7r = -6s + 8

Step 2: Rewrite Systems

2r + 8s = -4

Factor:                                               2(r + 4s) = -4Divide 2 on both sides:                    r + 4s = -2Subtract 4s on both sides:               r = -4s - 2Multiply -7 on both sides:                 -7r = 28s + 14

Step 3: Redefine Systems

-7r = 28s + 14

7r = -6s + 8

Step 4: Solve for s

Elimination

Combine equations:                     0 = 22s + 22Isolate s term:                                -22 = 22sIsolate s:                                         -1 = sRewrite:                                          s = -1

Step 5: Solve for r

Define equations:                    2r + 8s = -4Substitute in s:                         2r + 8(-1) = -4Multiply:                                    2r - 8 = -4Isolate r term:                           2r = 4Isolate r:                                    r = 2

Answer:

r = 2, s = - 1

Step-by-step explanation:

Given the 2 equations

2r + 8s = - 4 → (1)

7r = - 6s + 8 ( add 6s to both sides )

7r + 6s = 8 → (2)

Multiplying (1) by 7 and (2) by - 2, then adding will eliminate the r- term

14r + 56s = - 28 → (3)

- 14r - 12s = - 16 → (4)

Add (3) and (4) term by term to eliminate r , that is

44s = - 44 ( divide both sides by 44 )

s = - 1

Substitute s = - 1 into either of the 2 equations and solve for r

Substituting into (1)

2r + 8(- 1) = - 4

2r - 8 = - 4 ( add 8 to both sides )

2r = 4 ( divide both sides by 2 )

r = 2

solution is r = 2 , s = - 1

"If three angles and two sides of two triangles are congruent, are the triangles congruent? Why or why not?"

Answers

Answer:

yes

Step-by-step explanation:

because the corresponding angles are congruent, the triangles are congruent through CPCTC. If two sides are congruent and an included angle, then the triangles are congruent through the SAS postulate. And if two sides and a non-included angle are congruent then the triangles are congruent through the AAS postulate. Any way of looking at this proves congruency through various postulates, therefore the trianlges are congruent.
