Answer:

$5.99 for 1.5 lbs of gumballs

Step-by-step explanation:

You want to buy One and a half pounds of gumballs for $3.99 per pound. It is 3.99 for one pound of gumballs, so the price for half a pound of gumballs is half of that price.

3.99 / 2 = 1.995

Then add the price of 1 pound

3.99 + 1.995 = 5.985

Then you can round that up to 5.99

Answer:

X=-10

Step-by-step explanation:

Answer:

x = -10

Step-by-step explanation:

4.5(8-x) + 36 = 102 - 2.5(3x+24)

36 - 4.5x + 36 = 102 - 7.5x - 60

72 - 4.5x = 42 - 7.5x

72 + 3x = 42

3x = -30

x = -10

Answer:

C

Step-by-step explanation:

Prime factors: 2, 3, 3

Answer:

1.811

Step-by-step explanation:

To get the decimal Jenna should type into the computer you simply have to get the decimal value of each fraction and add them all together.

[tex]\frac{3}{4}=.75[/tex]

[tex]\frac{1}{8} =.125[/tex]

[tex]\frac{4}{5}=.8[/tex]

[tex]\frac{17}{125}=.136[/tex]

Then just add all the decimals together.

Answer:

1 1/2

Step-by-step explanation:

n= 3/2

Decimal Form:

n= 1.5

Mixed Number Form:

n = 1 1/2

Answer:

9.75

We know that the 2 triangles are proportional and are similar so that means there must be a scale factor between the sides of the triangles.

Answer:

14(cos(330)+isin(330))

Step-by-step explanation:

step1: determine the modulus using the formula  |z|=√(a²+b²)

|z|=  √((7√3)² + (-7)²) = √196 = 14

step2: determine the argument using the formula θ=tan⁻¹(y/x)

θ=  tan⁻¹(-7/7√3) =  (-1/√3) --> rationalize the denominator by multiplying top and bottom by √3 to get:  -√3/3

the tangent value on the unit circle that is -√3/3 is 330 degrees in quadrant iv

then put it together :p

Answer:

The smallest number you can add to 6412 to make it a perfect square is 149. Which would make 6561, and be the square 81

Step-by-step explanation:

Answer: y = 2x+12

Step-by-step explanation:

y = mx + b

the Ys are going down by 6 each time

the Xs are going adding up by 3 each time

radio: 6/3 = 2

that's our slope

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

when x is 0 then the y will be our b

which is 12

all together

y = 2x+12

Answer:

Yes,  -2 is a "rashihol" number

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]3x-24=81[/tex]

Collect like terms and simplify

[tex]3x=81+24\\\\3x = 105[/tex]

Divide both sides of the equation by 3

[tex]\frac{3x}{3} = \frac{105}{3} \\\\Simplify\\\\x = 35[/tex]

Answer:

  C.  √3

Step-by-step explanation:

When one of the factors is a rational number (0.5), the product will be irrational if, and only if, the other factor is irrational.

Of the numbers offered, only √3 is irrational.

  √3 will produce an irrational product when multiplied by 0.5.

The other values are all rational:

  A: 4

  B: 5/9

  D: 1/3

Answer:

1

Step-by-step explanation:

just keep the first number and flip the sign and it would be 1 i think idrk

Answer:

see below

Step-by-step explanation:

the circumference of a circle is

[tex]2\pi r[/tex]

in our problem

r=11

[tex]C=2\pi (11)\\\\=22\pi[/tex]

rounded to the nearest tenth

[tex]C\approx69.1[/tex]

the area of a circle is

[tex]\pi r^2[/tex]

so the area is

[tex]A=\pi(11)^2\\\\=121\pi[/tex]

rounded to nearest tenth

[tex]A\approx 380.1[/tex]

Answer:

9

Step-by-step explanation:

ok so first if the place you're rounding to is 5 or more you round up and if the place is 4 or less then it stays the same

8.5

5 is 5 or more so you round up

to 9

Step 1:

[tex]25+10x+x^2[/tex]

Let's split split 10x to factorise

Step 2:

[tex] = 25 + 5x + 5x + {x}^{2} [/tex]

Step 3:

[tex] = 5(5 + x) + x(5 + x)[/tex]

Step 4:

[tex] \green{= (5 + x)(5 + x)✓}[/tex]

Answer:

(x+5)(x+5)

Step-by-step explanation:

Let's arrange it in a proper manner first of all.

Step: Spilt 10x in order to factorize it.

x² + 10x + 25

0r, x² + 5x + 5x + 25

Step: Make two pairs from equation

x² + 5x + 5x + 25

0r, x(x+5) + 5(x+5)

Step: Take common thing from the given equation

x(x+5) + 5(x+5)

0r, (x+5)(x+5)

Hence, (x+5) and (x+5) are the factor for the given equation.

Answer:

I think its 229

if you take how many yellow marbles he got out of 7 it would be 3/7 and then I divided 400 by 7 and got 57. something so I multiplied 3 times 57 and got 171. So if you take 400-171 you get 229

Answer:

the answer for the number of stickers in all 4 boxes is 1200.

Step-by-step explanation:

there are 100 stickers in each roll and a box has 3 rolls. There are 12 rolls in total so you would do 100 X 12 which is 1200.

It's not clear what the pattern is supposed to be for the digits in the givne number. It looks like the repeating block should be 846, but it could just as easily be 84684.

Assume the first case, and let x = 7.846846846... . Then

1000x = 7846.846846846...

Subtract x from this to cancel the repeating decimal part, then solve for x :

999x = 7846 - 7 = 7839

x = 7839/999 = 871/111

If instead you meant the second case, let x = 7.846848468484684... . Then

10⁵ x = 784,684.846848468484684...

Solve for x :

99,999 x = 784,684 - 7 = 784,677

x = 784,677/99,999 = 261,559/33,333

Maybe you meant something else altogether?
