Answer:

64 oz. were consumed and 16 oz. were left.

Step-by-step explanation:

8*10 = 80 oz. of juice total.

10-2=8 boxes consumed

8*8(number of oz. per box)=64 oz. consumed

2*8=16 oz. left

64+16=80 checks out.

answer A , that could not be point

Answer:

Options a and c

Step-by-step explanation:

A unit circle is one which has origin as centre and radius as 1.

The equation of the unit circle would be

[tex]x^2+y^2 =1[/tex]

Thus we find that any point satisfying the above equation lies on the unit circle

Let us try the given points one by one

a) [tex](0.8)^2+(-0,6)^2 =1[/tex]. Hence lies on the circle

b) (1,1)

Cannot lie on circle since [tex]1^2+1^2 \neq 1[/tex]

c) [tex](\frac{-2}{3} ,\frac{\sqrt{5} }{3} )\\(\frac{-2}{3})^2+(\frac{\sqrt{5} }{3} )^2 =1[/tex]. Hence lies on the circle

d) [tex](\frac{\sqrt{3} }{2} ,\frac{1}{3} )\\(\frac{\sqrt{3} }{2})^2+(\frac{1}{3} )^2\\\neq 1[/tex]

Hence does not lie on the circle

Only option A,C are right

Answer:

60 cm, 60 cm, 32 cm, 32 cm

Step-by-step explanation:

Multiply each length by the scale factor.

15 cm * 4 = 60 cm

8 cm * 4 = 32 cm

The dilated sides AB and CD will have a length of 60 cm.

The dilated sides AC and BD will have a length of 32 cm.

Answer:

The error is:

He multiplied the dividend by 100 instead of 10

Step-by-step explanation:

∵ 1.926 ÷ 0.9 ⇒ means

  1.926 = 1926/1000 ⇒ dividend

  0.9 = 9/10 ⇒ divisor

* [tex]\frac{1926}{1000}[/tex] ÷ [tex]\frac{9}{10}[/tex]

 [tex]\frac{1926}{1000}[/tex] × [tex]\frac{10}{9}[/tex]

 [tex]\frac{1926}{100}[/tex] × [tex]\frac{1}{9}[/tex]

∵ 1926/100 = 19.26 ⇒ dividend

∴ 19.26 ÷ 9 = 1926/100 ÷ 9

  19 ÷ 9 = 2 with remainder 1/9

  12 ÷ 9 = 1 with remainder 3/9

  36 ÷ 9 = 4 no remainder

∴ The quotient is 214/100 = 2.14

Answer:He multiplied the dividend by 100 instead of 10

Answer:

s > 5

Step-by-step explanation:

s is the number of cookies Sue has.

Since she has more than 5 cookies, the number of cookies she has is greater than 5.

Hello there! An inequality modeling this could be x > 5.

When setting up this equation, we can use x to model the number of cookies that Sue has.

Remember that these are the symbols we use to represent inequalities:

< - greater than

> - less than

≤ - greater than or equal to

≥ - less than or equal to

Since the number of cookies Sue has is greater than 5 (but not equal to), we use the symbol.

We can represent her having x amount of cookies, which is more than 5, like this: x > 5,

I hope this helps and have a great day! :)

ANSWER

2160 cubes

EXPLANATION

The given rectangular prism has edge lengths,

9 inches,9inches and 3⅓ inches.

The volume of this rectangular prism is

[tex]V = 9 \times 9 \times \frac{10}{3} [/tex]

[tex]V = 3 \times 9 \times 10 = 270 {in}^{3} [/tex]

A cube with unit edges of length

[tex] \frac{1}{8} [/tex]

has volume.

[tex]v = {( \frac{1}{8}) }^{3} = \frac{1}{8} [/tex]

The number of unit cubes that can go into the prism is

[tex] = \frac{270}{ \frac{1}{8} } = 2160[/tex]

Answer:

2160 cm³

Step-by-step explanation:

The volume of a rectangular prism is calculated using the formula

V = lbh ( l is length, b is breadth, h is height )

here l = 18, b = 10 and h = 12, hence

V = 18 × 10 × 12 = 2160 cm³

Volume = l × b × h

= 18 × 10 × 12

= 2160cm³

[tex]g(2)\to\trext{put x = 2 to the equation of}\ g(x):\\\\g(2)=3(2)+2=6+2=8[/tex]

[tex]\dfrac{f(3)}{g(2)}=\dfrac{7}{8}[/tex]

Answer:

Please, refer to the images below

Step-by-step explanation:

We need to solve for x in the equation

cos (x+ pi) ^2 = sin (x)

cos (x+ pi) = - cos(x)

(-cos (x)) * (-cos (x)) = sin(x)

cos(x) ^2 = sin(x)

We know that

cos(x) ^2  + sin(x) ^2  = 1

cos(x) ^2 = 1 - sin(x) ^2

1 - sin(x) ^2 = sin(x)

sin(x) ^2 + sin (x) -1 = 0

Let A = sin(x)

A^2 + A - 1 = 0

(solutions attached in picture 1)

This means that

x = arcsin(A)

(solutions attached in picture 2)

Answer:

2W=9

Step-by-step explanation:

You must first get the Length, which is 15, and multiply it by 2 and you get 30. You then subtract 30 from 48 and get 18. Since the equation has 2W, you have to divide 18 by 2, which gets you the answer 9.

Answer:

width = 9 feet

Step-by-step explanation:

Here we are given that total length of the wood for the garden is 48 feet only.

The length in represented in the equation given below. In geometry we call it Perimeter.

2l+2w=48

Where l is the length of the garden and the w is width of the garden.

Here also given that , if Manny wants the length to be 15 feet, what will be width of the garden.

In order to find this we put the value of l as 15  in 2l+2w=48 and solve for w

Let us see how

2l+2w=48

2(15)+2w=48

30+2w=48

subtracting 30 from both sides

30+2w-30=48-30

2w=18

Dividing both sides by 2 we get

w=9

Hence the width will be 9 feet

Answer:

[tex]\frac{45-b}{25}[/tex]

Step-by-step explanation:

45 - b = 25m ← divide both sides by 25

[tex]\frac{45-b}{25}[/tex] = m

The cost of each song is $1.25.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Amelia used a $50 gift card to buy digital music online after playing for 16 songs her balance on the gift card was $30.

So, the cost of 16 song is 50-30=$20

Now, the cost of each song = 20/16

= 5/4

= $1.25

Therefore, the price of each song is $1.25.

Answer:

4 goals short

Step-by-step explanation:

To find how many shots Talia made - multiply the total number of shots (35) by 60% (or 0.60)

    35*.60 = 21 shots made

Subtract her goal (25) by the shots actually made (21)

    25-21 = 4 shots from her goal

Answer: 16

Step-by-step explanation: If 3 black circles equal 30, we can divide that by 3 and get 10. If 1 black circle and 2 white circles equal 18, we can subtract 10 and get left with 2 white circles worth 8, which means a white circle is 4. A white circle minus a square is 2, which means a square is 2. So we put this all together and get 16.

Answer:

b² - 7b - 18

Step-by-step explanation:

To multiply the factors.

Each term in the second factor is multiplied by each term in the first factor, that is

b(b - 9) + 2(b - 9) ← distribute both parenthesis

= b² - 9b + 2b - 18 ← collect like terms

= b² - 7b - 18

Answer:

The amount he will have at the end of 3 years is $3742.73

Step-by-step explanation:

* The formula for annual compound interest is:

A = P (1 + r/n)^(nt)

Where:

A = Total money after t years

P = the investment amount (the initial deposited amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years the money is invested

∵ P = $2860 ⇒ deposited

∵ r = 9% = 9/100 = 0.09 ⇒ annual rate

∵ n = 12 ⇒ compounded monthly

∵ t = 3 years

∴ A = 2860(1 + 0.09/12)^(12 × 3)

∴ A = 2860(1.0075)^36 = $3742.73

* The amount he will have at the end of 3 years is $3742.73

Answer:

The amount he will have at the end of 3 years = $3742

Step-by-step explanation:

Formula for compound interest

A = P[1 + R/n]^nt

A - Amount

P - Principle amount

R - rate of interest

n - Number of times in which the amount compounded

t - Number of years

To find the amount

Here,

P = $2,860, R = 9% = 0.09

n = 12 and t = 3 years

A = P[1 + R/n]^nt

 =2860[1 + 0.09/12]^(12*3)

 = 2860[1 + 0.0075]^36 = 3742.7257 ≈ $3742

First, calculate the amount of commission = .06 x $1,850 = $111

$350 + $111 = $461

Answer:

C

Step-by-step explanation:

Since there are no blue cards, the probability that you'd draw one is 0/12, which means that there is no chance you'll draw one.

It is impossible to get blue cards. Then the correct option is C.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

There are 4 red cards and 8 black cards in a bag.

In the bag, the number of blue cards will be zero.  

Thus, it is impossible to get blue cards. Then the correct option is C.
