A student ate 3/20 of all the candy and another 1.2 lb. Another student ate 3/5 of the candy and the remaining 0.3 lb. What was the total weight of the candy they ate?

Answers

Answer 1

Answer:

x = 6 lb

Step-by-step explanation:

Let

Total weight of the candy = x

3/20x + 1.2 lb + 3/5x + 0.3 lb = x

3/20x + 3/5x + 1.5 lb = x

3x+12x/20 + 1.5 lb = x

15/20x + 1.5 = x

1.5 = x - 15/20x

1.5 =20x -15x /20

1.5 = 5/20x

1.5 = 1/4x

x = 1.5 ÷ 1/4

= 1.5 × 4/1

= 6

x = 6 lb

What is the distance between the

(7.8)

Answers

To find the exact difference, we have to subtract the two decimal points.

1. First, we'll subtract the whole number. Then, we'll subtract the decimal number. This will make mental math easier.

a. 7 - 3 = 4

b. 8 - 2 = 6

2. Add the answers together to get your final answer.

a. = 4.6

The exact distance between the two points is 4.6. If you can't figure this strategy out, do algorithm. The simplist way to solve this is to use a calculator, which I checked my answer on. Have a nice day! :)

the distance between the two points would be 4.6

Steven is comparing the cost of a fresh lobster dinner at two different restaurants. The first
restaurant charges $51 for the meal, plus $2 per pound for the lobster he picks. At the
second restaurant, Steven would pay $4 per pound for the lobster, in addition to $19 for the
meal. Steven realizes that, in theory, dinner at both restaurants could cost the same amount
if the lobster had a certain weight. How much would Steven pay for his dinner? What is the
weight?

Answers

Answer:

Step-by-step explanation:

2x+51=4x+19

32=2x

x=16. The weight is 16 pounds

plug it back in to find the cost

32+51=83. 64+19 = 83. The cost is 83 dollars

A freight train traveling along a certain route uses 12 units of fuel per mile plus an additional 2.2 units of fuel per mile for each railcar on the train. Let N represent the number of railcars on the train. What is an expression for f(N), the total number of units of fuel used per mile? find f(12). How many railcars does the train have if f(N)=34?

Answers

Answer:

[tex]38.4\ \text{units of fuel/mile}[/tex]

10

Step-by-step explanation:

Let [tex]N[/tex] represent the number of rail cars on the train

Each rail car adds 2.2 units of fuel per mile.

Fixed fuel consumption is 12 units of fuel per mile

The function of fuel consumption per mile is

[tex]f(N)=12+2.2 N[/tex]

when

[tex]N=12[/tex]

[tex]f(12)=12+2.2\times 12\\\Rightarrow f(12)=38.4\ \text{units/mile}[/tex]

[tex]\boldsymbol{f(12)=38.4\ \text{units/mile}}[/tex]

[tex]f(N)=34\\\Rightarrow 12+2.2N=34\\\Rightarrow N=\dfrac{34-12}{2.2}\\\Rightarrow N=10[/tex]

So, the number of rail cars when [tex]f(N)=34[/tex] is 10.

On a chapter test, Stephanie uses the rules of equation solving and inverse operations to solve the cubic equation below. The directions on the test are not very specific, however, they do say to give an exact solution. Stephanie is not sure if she should submit a decimal approximation or a simplified radical as the answer.

4x3 = 756

What recommendation can you make to Stephanie regarding her answer to the cubic equation above? In your recommendation, explain what the term "exact" indicates with regards to the solution.
Solve the cubic equation from Stephanie’s test. Submit two solutions for the equation- a) your answer as a decimal approximation, rounded to the nearest hundredth, and b) as a simplified radical. Use substitution to check each version of your solution in the original equation.
After solving the test question and checking both the decimal solution and the simplified radical form, would you change your recommendation (in Part 1) to Stephanie regarding the format of her answer? Use complete sentences to explain your reasoning.

Answer:

The y-intercept is (0, 5) and the x-intercept is (2.5, 0).

What is an intercept of the straight line?

In the context of a straight line in a two-dimensional plane, an intercept refers to the point(s) where the line intersects with one or both of the coordinate axes (i.e., the x-axis and the y-axis).

To find the y-intercept, we set x = 0 and solve for y:

-4(0) + 7 = 2y - 3

7 = 2y - 3

2y = 10

y = 5

Therefore, the y-intercept is (0, 5).

To find the x-intercept, we set y = 0 and solve for x:

-4x + 7 = 2(0) - 3

-4x + 7 = -3

-4x = -10

x = 2.5

Therefore, the x-intercept is (2.5, 0).

Answers

Answer:

Step-by-step explanation:

is your qustion like -8-16 because its -24

Answer:

y = 4x + 16

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (- 8, - 16) into the partial equation

- 16 = - 32 + c ⇒ c = - 16 + 32 = 16

y = 4x + 16 ← equation of line

Chet started to slow his eating speed down later in the evening. He was
now eating only 1/4 of a turkey every 2 hours. What was his unit rate
later in the evening?

Answers

Answer:

The unit rate is:

1/8 turkey/per hour.

Step-by-step explanation:

As Chet was eating 1/4 of a turkey every 2 hours.

This tells us that every two hours, Chet will eat  175  1/4 of a turkey.

Unit rate basically means 'how much of something per 1 unit of something else'.

A unit rate is a rate with a denominator of  1  unit.

This means, in 1 hour, Chet will eat half of what he eats every 2 hours.

so Chet will eat [tex]\frac{\frac{1}{4}}{2}=\frac{1}{8}[/tex] of a turkey in 1 hour.

i.e.

[tex]\frac{\frac{1}{4}}{2}=\frac{1}{8}[/tex]

Therefore, the unit rate is:

1/8 turkey/per hour.

The dimensions for a rectangular prism are x + 7 for the length, x + 9 for the width, and x for the height. What is the volume of the prism? Enter your answer as a polynomial in standard form. The volume of the prism can be expressed as _____.

Answers

Answer:

The volume of the prism is x^3 + 16x^2 + 63x

Step-by-step explanation:

Mathematically, the volume of the prism is the area of the base multiplied by the height of the prism

The area of the base is l * w

= (x + 7)(x + 9) = x^2 + 7x + 9x + 63 = x^2 + 16x + 63

The volume is now; x(x^2 + 16x + 63)= x^3 + 16x^2 + 63x

1/4×l +(2 1/2) = 4l = 6

Step-by-step explanation:

For l laps around a 1/4 mile track, the total distance is ...

  l×(1/4)

After adding 2 1/2 miles to that, Gabriella's total distance was 4 miles:

  l×(1/4) +(2 1/2) = 4 . . . . an equation to find l

__

We can solve this equation by subtracting 2 1/2, then multiplying by 4.

  l×(1/4) = 1 1/2

  l = 4(1 1/2)

  l = 6
