Which expression is equivalent to 250 + 150 ?

Answer:

64 ounces of carrots

Step-by-step explanation:

4×16=64

Answer:

64 ounces

Step-by-step explanation:

There are 16 ounces in 1 pound.

If you know that 16 ounces is 1 pound, then you know that 4 pounds must be 16 * 4.

16 * 4 = 64 ounces

Answer:

X = -6 - 3y

Y = -1

Step-by-step explanation: Solve for X first using basic algebra. Plug in X vaalue to original equation and solve. -6 - 3y + 3y = -6. Solve by adding 6 to both sides of the equation and dividing -3y by 3y.

Answer:

12+8k

Step-by-step explanation:

I can start by combining the like terms in the equation which is 10 and 2. 10+2=12. My final answer would be 12+8k because 8k and 12 are not like terms so I cannot proceed in this case and leave it as my answer.

Answer:

  244 tiles

Step-by-step explanation:

These "border" problems can be a little tricky.

The tiles are 1 ft square, so an integer number of them fit along each of the sides. The 40-ft side will take 40 tiles for its border, and the 80-ft side will take 80 tiles.

The total number of tiles along each of the four sides is ...

  40 + 80 + 40 + 80 = 240 . . . tiles

However, there is also a tile in each of the corners. There are 4 of those, so the total number of tiles surrounding the pool is ...

  240 +4 = 244 tiles

__

Alternate solution

For a border of width w, the outside area of the pool plus the border is ...

  A = LW = (80 +2w)(40 +2w) = 80·40 +240w +4w²

The area of the pool is ...

  A = LW = (80)(40) = 80·40

Subtracting the area of the pool from the total area including the border gives ...

  border area = (80·40 +240w +4w²) -(80·40) = 240w +4w²

We know the width of the border is 1 foot, so w=1 and the border area is ...

  border area = 240·1 +4·1² = 244 . . . . square feet

Each tile is 1 square foot, so 244 tiles are needed for the border.

_____

It can help to draw yourself a diagram. It can also help to make a small model using blocks, Scrabble tiles, Legos, jigsaw puzzle pieces, squares cut from paper, or even coins (pennies). Anything that will give you an idea of how to count the tiles required to make a border can be helpful.

Answer:

Mean will be affected.

Step-by-step explanation:

The mean value of the data set will be affected as it depends on the magnitude of data points and not its position. The median however will not change since it depends on the relative position of data points.

Question 38 . Cos ∅ = 12/13   ∅ in Quadrant-4(Where only Cos & Sec are Positive all other Functions Are Negative in this Quadrant)

Now ∅ Represent a Right Angle Triangle with Base=12 Perpendicular=5 & Hypothenese=13

Sin∅ = -5/13 , Cosec∅=-13/5 , Tan∅=-5/12 , Cot∅=-12/5 & Sec∅=13/12

Question 39 . SinX=-3/4   X Lies in Quadrant-3(Where only Tan & Cot are Positive all other Functions Are Negative in this Quadrant)

Find By Using Basic Formulas

[tex]SinX^{2}+CosX^{2}=1[/tex] ↔ Put Value of Sin∅=-3/4

We get CosX= ±[tex]\frac{\sqrt{5} }{4}[/tex] (but X Lies in Quadrant-3 Where Cosine Is Negative , So Neglect CosX= +[tex]\frac{\sqrt{5} }{4}[/tex])

Answer:

66.32

Step-by-step explanation:

Hello!

[tex]\large\boxed{66.32 m}[/tex]

We are given the area, so we can solve for the width given the length:

A = l × w

Thus:

272.4 = 15 × w

w = 18.16 m

The perimeter of a rectangle can be calculated using this equation:

P = 2l + 2w

Therefore:

P = 2(15) + 2(18.16)

P = 30 + 36.32 = 66.32m

Answer:

Angle BAC corresponds with side length BC

Side length AC will correspond with angle ABC

Step-by-step explanation:

In a triangle, the side length will correspond to the angle opposite it and vice versa.

That is, the side length opposite angle A corresponds to the side of Angle A

Hence, in the triangle given above ;

Angle BAC corresponds with side length BC, because BC is opposite BAC

Side length AC will correspond with angle ABC, because AC is directly opposite angle ABC.

Answer:

(60.382 ; 83.998)

Step-by-step explanation:

The confidence interval is given as :

Mean ± Margin of error

Mean = 72.19

The margin of error is : Tcritical * s/√n

n = 13 ; s = 15.88

Tcritical at 98%, df = 13-1 = 12 = 2.681

Margin of Error = 2.681 * 15.88/√13 = 11.808

Confidence interval = 72.19 ± 11.808

(60.382 ; 83.998)

Answer:

Proportional

Step-by-step explanation:

Proportional functions can be written as [tex]y=kx[/tex], where [tex]k[/tex] is some constant of proportionality. Plugging in (x,y) pair into this function will yield a constant of proportionally of [tex]k=\frac{3}{2}[/tex] and since this constant is maintained through all the coordinate pairs in the table, the table is proportional.

Answer:

x =150 men

Step-by-step explanation:

Think of the total as workdays

125men* 120days = 15000 workdays

We still need 15000 workdays

100 days * x = 15000workdays

Divide by 100

x = 15000/ 100

x =150 men

Answer:

150 men

Step-by-step explanation:

120 × 125 = 15000

15000 ÷ 100

Answer:

-74

Step-by-step explanation:

f(x) = -2x^2 +8x -10

Let x = -4

f(-4) = -2 ( -4)^2 +8(-4) -10

     = -2(16) -32-10

     = -32 -32-10

    = -74

Answer:

C

Step-by-step explanation:

We have the equation:

[tex]4x^2+5x=-10[/tex]

Add 10 to both sides to isolate the equation.

[tex]4x^2+5x+10=0[/tex]

This is not factorable*, so we can use the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

In this case, a = 4, b = 5, and c = 10.

Substitute:

[tex]\displaystyle x=\frac{-(5)\pm\sqrt{(5)^2-4(4)(10)}}{2(4)}[/tex]

Simplify:

[tex]\displaystyle x=\frac{-5\pm\sqrt{-135}}{8}[/tex]

Since we cannot take the root of a negative, we have no real solutions.

Our answer is C.

*To factor something in the form of:

[tex]ax^2+bx+c=0[/tex]

We want two numbers p and q such that pq = ac and p + q = b.

Since ac = 4(10) = 40. We need to find two whole numbers that multiply to 40 and add to 5.

No such numbers exist, so the equation is not factorable.

Answer:

c) No Real Solution

Step-by-step explanation:

I'ma try my best to explain it!

We have: 4x^2+5x=−10

Step 1: Subtract -10 from both sides.

4x^2+5x−(−10)=−10−(−10) (you don't put the -10 next to it but you put it in the bottom)

Then we get 4x^2+5x+10=0 from the subtraction above

For this equation: a=4, b=5, c=10

4x^2+5x+10=0

Then we use quadratic formula with a=4, b=5, c=10

The answer is the picture below: means no solution

Hope this helps and is correct!
