Two boxes can hold the same amount of sand. Box 1 is 1/4 filled and box 2 is 2/3 filled. If the sand in box2 is poured into box 1, what is the fraction of box 1 still not filled a.1/12 b.3/7 c.4/7 d.11/12

Answer:

6/7

Step-by-step explanation:

First, find two points that fall on the line and are coordinates on the graph.

The two points I found were (3,5) and (10,11).

Use the slope formula to come up with the slope.

[tex]slope = \frac{change in y}{change in x}[/tex]  

slope = [tex]\frac{11-5}{10-3}[/tex] = [tex]\frac{6}{7}[/tex]

Answer:

Boys = 114

Girls = 145

Step-by-step explanation:

Boys = b

Girls = 2b-83

b+2b-83=259

3b=259+83

3b=342

b=114

Boys = b = 114

Girls = 2b-83=228-83=145

The number of boys is 114 and the number of girls is 145

The given expression in algebraic form is written as:

let the number of boys = b

then, the number of girls, g = 2b - 83

given total number of students, t = 259

To find:

Set the following equations to find the number of boys and girls:

number of boys + number of girls = total number of students

[tex]b + g = 259\\\\b + 2b -83 = 259\\\\3b = 259+83\\\\3b = 342\\\\b = \frac{342}{3} \\\\b = 114\\\\The \ number \ of \ girls = 2(114) - 83 = 145[/tex]

Thus, the number of boys is 114 and the number of girls is 145

Part A is correct. We have x+15 as the length and x+3 as the width. Convention usually has the width be the smaller of the two.

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

Part B will have you replace x with 8 and simplify

length = x+15 = 8+15 = 23

width = x+3 = 8+3 = 11

the rectangle is 23 yards by 11 yards, so the area is 23*11 = 253 square yards

Answer:

Below

Step-by-step explanation:

As we see the area is expressed as second degree polynomial

We have already a side wich is (x+15)

● x^2 +18x + 45 = w × (x+15)

● w = (x^2 +18x+45)/(x+15)

Using the eucledian division we get:

● w = x+3

Since x^2 +18x +45 = (x+15) × (x+3)

So your answer was right

■■■■■■■■■■■■■■■■■■■■■■■■■■

Let's calculate the dimensions if x= 8 yards

● the length

x+15 = 8+15 = 23 yards

● the width

x+3 = 8 + 3 = 11 yards

● the area

(x+15)×(x+3) = 23 × 11 = 253 yards^2

Step-by-step explanation:

you need to factor out the 2 from the expression, add common like terms, factor out -2 from the expression, multiply a positive and a negative to get a negative, then multiply the numbers, and you'll get your answer

BAE + HEG = 180°

124 + 2x+6 = 180°

2x+6 = 56

x = 50/2

x = 25°

Reason:

Given

HEG = EAD since they are corresponding angles

EAD + EAB = 180° since they are supplementary angles.

Answer:

15 cm

Step-by-step explanation:

The area of an equilateral triangle is:

[tex]\frac{\sqrt{3} }{4}a^2[/tex], where a is the length of one side.

We can find the value of a (the length) by:

[tex]\frac{25\sqrt{3} }{4} = \frac{\sqrt{3} }{4}a^2[/tex]

[tex]a^2 = 25[/tex]

a = 5, so the side length of this triangle is 5 cm.

The perimeter of an equilateral triangle will be 3 times the length.

Answer:

  all values except one (-2)

Step-by-step explanation:

The function heads off toward infinity at x=-2, so it is not defined there. The function is defined for all values except one.

Answer:

x = 1

Step-by-step explanation:

−31−4x=−5−5(1+5x)

First step is to simplify both sides

−31−4x=−5−5(1+5x)

−31+−4x=−5+(−5)(1)+(−5)(5x)

distribute

−31+−4x=−5+−5+−25x

−4x−31=(−25x)+(−5+−5)

and combine like terms

−4x−31=−25x+−10

−4x−31=−25x−10

Then add 25x to both sides

−4x−31+25x=−25x−10+25x

21x−31=−10

Add 31 to both sides

21x−31+31=−10+31

21x=21

And divide by 21!

21x/21 = 21/21

x=1

Answer:

X=1

Step-by-step explanation:

First this is you want to distribute the -5 to the 1 and 5x. Now you should have -31-4x=-5-5-25x. Next thing is to combine your like terms which would be -5 and -5 and you get -10. (-31-4x=-10-25x) Now add 31 to both sides and your new solution is -4x=21-25x. This time you add 25x to both sides and get 21x=21. Final step you divide both sides by 21 and get X=1. :)

Step-by-step explanation:

The number of oranges he has is a multiple of 6, so the number can be

6, 12, 18, 24, 30, 36, 42, 48, 54, etc.

He sells one orange, so now he an have:

5, 11, 17, 23, 29, 35, 41, 47, 53, etc.

All numbers above up to 53 are multiples of 1, so n can be 1.

Also 5 and 35 are multiples of 5, so n can be 5.

All numbers other than 5 and 35 are prime.

Answer: 2

Answer:

width = 10

length = 2 (10) + 7 = 27

Step 1:

If the perimeter was 74 inches, then that means one side of the width and one side of the length added together is 1/2 of 74, which is 37.

Step 2:

We can solve this by using this equation:

2w + 7 + w = 37

Then, we subtract 7 from both sides, since in the passage, it states that the length is 7 more than twice the width.

2w + w = 30

Add the w's together:

3w = 30

And then divide both sides by 3 to get:

w = 10

Step 3:

Now, we can plug in w into our equation to solve for the width and length.

width = 10

length = 2 (10) + 7 = 27

Answer:

your anwser is 4 x + 2 y − 3 z − 3

Step-by-step explanation:

Simplify:4 x + 2 y − 3 z − 3

Answer:

4x + 2y - 3z -3.

Step-by-step explanation:

2x+5y+z-6)+(6x-4y-z+7)+(-4x+y-3z-4)

Removing the parentheses:

= 2x + 5y + z - 6 + 6x - 4y - z + 7 - 4x + y - 3z - 4

Bringing like terms together:

= 2x + 6x - 4x + 5y - 4y + y + z - z - 3z - 6 + 7 - 4

Simplifying like terms we have:

4x + 2y - 3z -3.

Geometery is used everywhere you go. Construction blueprints, the design of assembly systems in manufacturing, nanotechnology, computer graphics, visual graphs, video game programming virtual reality creation, and etc. It has given us what we have today and why we have everything today. Without geometry to help us how would construction know how to build the bridge so it won't fall. It benefits us in ways people don't expect but everyone should learn it so we can recognize the importance of math to the real world.

Answer:

Step-by-step explanation:

Given the expression cos(2β)=√3/2 for 0≤β<2π, we are to find the value of β within the range that satisfies the equation.

[tex]cos(2\beta)=\sqrt{ 3}/2\\\\take \ the\ arccos\ of \ both \ sides\\\\cos^{-1}cos(2\beta) = cos^{-1}\sqrt{{3} }/2 \\ \\2\beta = cos^{-1}\sqrt{{3} }/2 \\\\2\beta = 30^0\\\\\beta = 30/2\\\\\beta = 15^0[/tex]

Since cos id positive in the 4th quadrant, [tex]\beta = 360^0-15^0[/tex], [tex]\beta = 345^0[/tex]

Hence the value of [tex]\beta[/tex] that satisfy the equation are 15° and 345°

Converting to radians;

180° = πrad

15° = 15π/180 rad

15° = π/12 rad

345° = 345π/180

345° = 23π/12 rad

The values in radians are  π/12 rad and  23π/12 rad

Answer:

[tex]x > 1610[/tex]

Step-by-step explanation:

Given that the empire fell in 1610

Required

Represent years after the fall of the empire using inequality

From the question, we understand that

1. x represent years

2. The empire fell in 1610

This implies that, years before (and including) 1610 are invalid and we only have to consider years after 1610;

Years such as 1611, 1612, 1613.......

All the aforementioned years are greater than 1610;

The keyword is greater than 1610

And this can be represented as [tex]x > 1610[/tex]

P=20x-0.01x^2-240

P=20(300)-0.01(300)^2-240

P=6000-0.01(90000)-240

P=6000-900-240

P=4860

Remember PEMDAS

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

EXPLANATION: first Is Parentheses, which would be 300, multiply that by 20, that would be 6000.

Next is Exponents, which would be the (^2) so you would Multiply the 300 by itself 2 times. which is 90000

Next is Multiplication, Multiply 0.01 by 90000, which would be 900.

There is nothing to divide or add so skip that.

Next is subtraction, subtract 6000-900-240 and the answer would be 4860.

so Faith's prediction profit for this season would be 4860 when her orchard produces 300 bushels of apples.

I hope that helped! Good Luck!
