You work on a concrete crew starting a construction project. Once the pouring begins, it must continue non-stop until it is completed. Your crew will work an 8-hour shift along with two other crews. The total project requires 175,000 yards of concrete. Your supervisor estimates that each crew will pour around 1200 yards per hour. How many consecutive days should you plan to work on this project?

Answer:

5.7-18y=1

Step-by-step explanation:

52-9y=3

5.2-9y=-2

or,57.2-18y=1

Answer:

-18y = 46.8

Step-by-step explanation:

Adding Left hand side elements together as well as right hand side

Eq1 = equation 1

Eq2 = equation 2

LHS(left hand side of the equation)

RHS(right hand side of the equation)

LHS of Eq1 + LHS of Eq2 = RHS of Eq1 + RHS of Eq2

-52 -9y + 5.2 -9y = 3 - 2

=> -9y -9y - 52 + 5.2 = 1

=> -18y - 46.8 = 1

=> -18y - 46.8 = 0

=> -18y = 46.8

25

Step-by-step explanation:

Answer:yes

Step-by-step explanation:

Answer:

Infinite solutions

Step-by-step explanation:

So if simplified it would be

-3x+15=15-3x

Which is basically the same thing if arranged

15-3x=15-3x

-3x+15 can also be 15-3x still the same thing as adding 15 to -3x

So since these are equal anything could be used

like try 0

Both get 15

Try 1

Both get 12

Try legit any number

youll get the same results (I would choose 3 positive easy ones, 0,1,2 and 3 negative ones -1,-2,-3)

Answer:

The ratio of books sold to movies sold at the store is 4:1.

Step-by-step explanation:

Given that:

Number of movies sold at the store = 2 movies

Number of books sold at the store =  8 books

Ratio of books sold to movies sold at the store is

Books sold : Movies sold

8 : 2

[tex]\frac{8}{2}:\frac{2}{2}[/tex]

4 : 1

Hence,

The ratio of books sold to movies sold at the store is 4:1.

Answer:

The answer must be D

Step-by-step explanation:

When a shape like a trapezoid is rotated, the figure will remain the same which means that a rotation will not change the measure of the angles, or the measure of the sides, therefore d must be correct because a rotation is a rigid transformation.

Answer:

              J < -7

Explantion:

Rewrite so J is on the left side

                  -20j > 140

               Divide each term by -20 and simplify

                   j < -7          

Answer:

0.032% probability of this happening

Step-by-step explanation:

Since the distribution is very large(10,000 skittles), and there are only two possible outcomes(either the Skittles is green or it is not) we can use the binomial probability distribution as an approximation.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Handful of 5 skittles:

This means that [tex]n = 5[/tex]

20% of the Skittles are green

This means that [tex]p = 0.2[/tex]

What is the probability of this happening?

Probability of all skittles being green, so [tex]P(X = 5)[/tex].

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 5) = C_{5,5}.(0.2)^{5}.(0.8)^{0} = 0.00032[/tex]

0.032% probability of this happening

Answer:

the first one is 267% and 400%

Step-by-step explanation:

but i don't know for the 2nd

Answer:

2/3 is 266.666667% of 1/4

2/3 is 400% of 1/6

Step-by-step explanation:

You just need to divide the second number by the first:

2/3 ÷ 1/4 = 2/3 · 4 = 2 2/3 which, in a percentage, is 266.666667.

2/3 ÷ 1/6 = 2/3 · 6 = 4 and 4 as a percentage is 400%

Answer:

5/12

Step-by-step explanation:

The whole book is 1.

So This will be your equation.

1/3 + 1/4 = 1

4/12 +3/12 = 1

7/12 = 1

Now you minus 7/12 from 1

1-7/12 is how much is left

12/12-7/12= 5/12

The fraction that represents the book john has left to read is 5/12.

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.

Given is that John read 1/3 of his book on the first day and 1/4 of the book on the second day.

Assume that the fraction that represents the book john has left to read is [x/y]. Then, we can write -

1/3 + 1/4 + x/y = 1

x/y = 1 - 7/12

x/y = 5/12

Therefore, the fraction that represents the book john has left to read is 5/12.

Answer:

1/16 or 0.0625

Step-by-step explanation:

Im not sure but this may be the answer

The given fraction in simplest form is 1/16.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

The given fraction is 2⁻⁴/4⁰.

Now, 2⁻⁴/4⁰ =2⁻⁴/4⁰

= 2⁻⁴/1

= 1/2⁴

= 1/16

Therefore, the given fraction in simplest form is 1/16.

Given:

[tex]\tan A=\dfrac{1}{5}[/tex]

[tex]\tan B=\dfrac{1}{4}[/tex]

To find:

The value of [tex]\tan^2(A-B)[/tex].

Solution:

We know that,

[tex]\tan (A-B)=\dfrac{\tan A-\tan B}{1+\tan A\tan B}[/tex]

Putting the given values, we get

[tex]\tan (A-B)=\dfrac{\dfrac{1}{5}-\dfrac{1}{4}}{1+\dfrac{1}{5}\cdot \dfrac{1}{4}}[/tex]

[tex]\tan (A-B)=\dfrac{\dfrac{4-5}{20}}{1+\dfrac{1}{20}}[/tex]

[tex]\tan (A-B)=\dfrac{\dfrac{-1}{20}}{\dfrac{20+1}{20}}[/tex]

[tex]\tan (A-B)=\dfrac{-1}{21}[/tex]

Taking square on both sides, we get

[tex]\tan^2 (A-B)=\left( \dfrac{-1}{21}\right)^2[/tex]

[tex]\tan^2 (A-B)=\dfrac{1}{441}[/tex]

Therefore, the value of [tex]\tan^2(A-B)[/tex] is [tex]\dfrac{1}{441}[/tex].
