Answer:        

8 ounces of 20%12 ounces of 70%

Step-by-step explanation:

Let 'x' be the number of ounces of 20% solution'y' be for the 70%

solutionSince the the mix is 50% of 20 ounces then:x + y = 200.20x +

0.70y = 0.50(20)From the 1st equation solve for xx = 20 - ySubstitute it to

the 2nd equation0.2(20-y) + 0.7y = 104 - 0.2y + 0.7y = 100.5y = 10-40.5y =

6y = 12Substitute to x = 20 - yx = 20 - 12x = 8

Step-by-step explanation:

Answer:

3 = (50.000%)

4 = (66.667%)

Step-by-step explanation:

3 out of 6 = 3/6

4 out of 6 = 4/6

3/6 in decimal form is 0.5

4/6 in decimal form is 0.6666 (the six repeats forever)

0.5 out of 1 is 50%

0.6666 (the six repeats forever) out of 1 is about 66.667%

0.5 = (50.000%)

0.66667 (rounded) = (66.667%)

Answer:

105 cookies

Step-by-step explanation:

We can model Karen's cookie situation like so:

#TotalCookies = #RecentlyBought + #AlreadyHad

We know that Karen already had 9 cookies in a jar, so it now looks like.

#TotalCookies = #RecentlyBought + 9

The number she recently bought, involves multiplication. So she bought 6 bags of 16 cookies. That's 6 x 16 = 60 + 36 = 96

#TotalCookies = 96 + 9 = 105 cookies

Karen loves cookies!

Answer:

105 cookies

Step-by-step explanation:

Given:-

To find:-

Solution:-

total no. of cookies :- new cookies + old cookies

Answer:

7%

Step-by-step explanation:

First, let's add the 20 dogs and 15 cats together to find the total number of animals adopted

20 + 15 = 35 animals adopted

We cand do 35 ÷ 200 to find how much of a percent 35 is of 500

35 / 500 = 0.07

Multiply this number by 100 to get a percent

0.07 × 100% = 7%

7% of the animals

Answer:

[14] 139

[15] 90

[16] 41

[17] 49

[18] 139

[19] 131

Step-by-step explanation:

[14] Since m ∠ CEB is vertical with m ∠ AED = 139

[15] Knowing that m ∠FBD = 90 degree then m ∠ CEF = 90 degree

[16] Since m ∠ DEB is vertical to m ∠ADC Thus answer = 41

Note: vertical angles are angles opposite each other where two lines cross.

[17] Since m ∠ FED = 90 degree and m ∠ DEB = 41 then 90 - 41 = 49

[18] To Find m ∠CEB we have to subtract from m ∠ DEB

180 - 41 = 139

[19] Knowing that m ∠ FED = 90 degree and m ∠DEB = 41

Then m ∠ AEF =  90 +41=131

Answer:

Step-by-step explanation:

Remark

These two angles are supplementary. They make up the horizontal line. Supplementary angles add to 180 degrees.

Equation

x + 134 = 180

Solution and Answer

x + 134 = 180                    Subtract 134 from both sides

x + 134 - 134 = 180-134    Combine

Answer: x = 46

Answer:

80

Step-by-step explanation:

For these types of counting problems, just multiply all of the levels.

For example, this would be

4 choices

5 choices

4 choices

Multiply 4*5*4, and you get 80.

Total number of ways of combining one level from each of the growth factors is equals to 80.

" As per fundamental principle of counting if first event has 'm' number of possible outcomes , second has 'n' number of possible outcomes then total number of ways are m× n ."

According to the question,

Number of growth factors =3

First growth factor: Lightening

Second growth factor: Age

Third growth factor : Temperature

As per the data given we have,

Number of levels in lightening 'm'= 4

Number of levels in age 'n'= 5

Number of levels in temperature 'p' =4

Substitute the value as per the definition of fundamental principle of counting

Total number of ways = m × n × p

                                     = 4 × 5 × 4

                                     = 80 ways

Hence, total number of ways of combining one level from each of the growth factors is equals to 80ways.

Answer:

No

Step-by-step explanation:

Since gravity falls at a rate of 16 feet per second, t= number of seconds.

if t=2 seconds, you would have the equation 16*2 = fall amount

16*2 =32. Since it is less than 60 feet, the backpack won't hit the ground in 2 seconds

Answer:

1/36

Step-by-step explanation:

Meal: 4 choices

Side: 3 choices

Beverage: 3 choices

Total number of possible combinations: 4 × 3 × 3 = 36

The specific combination of cheese pizza, apple, and milk is 1 of the 36 possible choices.

p(cheese pizza, apple, milk) = 1/36

Answer:

e

Step-by-step explanation:

We first have to find out how many outcomes there are in total. That means finding out how many meals, sides, and beverages there are.

Meals: cheese pizza, cheeseburger, hotdog, and salad (4)

Sides: banana, apple, and yogurt (3)

Beverages: milk, water, and juice (3)

4 x 3 x 3 = 36

There are 36 possible outcomes.

We need to find the probability that Zoe will choose cheese pizza, an apple, and milk. Those are three outcomes.

The probability is 3/36.

The fraction 3/36 can be simplified to 1/12.

Answer:

This line has a slope of 0, with the equation being y = -4

Step-by-step explanation:

  Slope can be found with change in y over change in x

[tex]\frac{-4--4}{-2--3} =\frac{-4+4}{-2+3}=\frac{0}{1} =0[/tex]

       Note: We can tell by just looking at the line it will have a slope of 0. A line straight up and down vertically is one with an undefined slope, but a horizontal line has a slope of 0 since there is no incline/decline.

Answer: 909.03

Step-by-step explanation:

We know that the equation is an exponential function, it can be written as y=ab^x

[tex]100 &=a b^{6.5} \dots \mathrm{Equation \ 1} \\11 &= a b^{1} \\[/tex]

[tex]\Rightarrow ab^1=11[/tex]

[tex]\Rightarrow \frac{ab^1}{b}=\frac{11}{b};\quad \:b\ne \:0[/tex]

[tex]\Rightarrow a=\frac{11}{b}[/tex]

a = 11/b, substitute it in equation 1

[tex]100 &=a b^{6.5}[/tex]

[tex]\Rightarrow 100=\left(\frac{11}{b}\right)b^{6.5}[/tex]

[tex]\Rightarrow 100b=11b^\frac{11}{2}[/tex]

[tex]\Rightarrow 11\sqrt{b^{11} } =100b[/tex]

[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]

[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]

[tex]\Rightarrow {b^{11} } =\frac{10000}{121}}[/tex]

[tex]\Rightarrow {b} =\frac{\sqrt[11]{10000 \cdot 11^9} }{11}[/tex]

[tex]\Rightarrow {b} = 1.49379[/tex]

a = 11/b

a = 11/(1.49379)

a = 7.36382

Equation: y = (7.36382)(1.49379)^x

Now plug in 12 for x:
[tex]\Rightarrow { \left(7.36382\right)\left(1.49379\right)^{12}[/tex]

[tex]\Rightarrow 7.36382\cdot \:1.49379^{12}[/tex]

[tex]\Rightarrow 7.36382\cdot \:123.44530\dots[/tex]

[tex]\Rightarrow 909.03[/tex]

Therefore, f(12) = 909.03 for the exponential function
