A chemist is using 336 milliliters of a solution of acid and water. If 16.4% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.

Answer:

(1,4.5)

([tex]\frac{5+(-3)}{2} ,\frac{3+6}{2}[/tex])

Answer:16

Step-by-step explanation:Next day there will be (36+12) or 48 players.

For 36 players 12 pizzas are needed

For 1 player 12/36 pizzas are needed

For 48 players 12/36*48 or 16 pizzas are needed

The number of pizzas that 12 players will need is 4 based on the given ratio.

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

The ratio of pizza to players = 36/12

With the same ratio,

The number of pizzas required for x number of 12 players,

12/x = 36/12

x = 144/36 = 4

Hence "Based on the above ratio, 12 players will require 4 pizzas.".

Answer:

So the rate of decay is 0.25, or 25%.

Step-by-step explanation:

The variable r gives the rate of decay in the formula f(x) = P(1 − r)x = 16(1 − 0.25)x.

Answer:

Exponential decay, 75% decrease

Answer:

200 people were at the stadium

Step-by-step explanation:

Let us represent the total number of people at the stadium = x

At a football stadium, 5% of the fans in attendance were teenagers. If there were 10 teenagers at the football stadium

Hence:

5% of total number of people = 10 teenagers

5/100 × x = 10

5x/100 = 10

Cross Multiply

5x = 100 × 10

5x = 1000

Divide both sides by 5

5x/5 = 1000/5

x = 200

The total number of people in the stadium is 200

Answer:

y=2

Step-by-step explanation:

Distribute the 2 into 3y and -6:

6y-12=0

Move the -12 to the other side by adding both sides by 12:

6y-12+12=0+12

=

6y=12

divide both sides by 6:

y=2

Answer:

which way are the arrows facing on the graph? How many times does the fuction change directions?

Step-by-step explanation:

if arrows are going in same direction, degree is even and then count the number of direction changes for exact number

if arrows are going in opposite directions, degree is odd and then count direction changes

Answer: 7

Step-by-step explanation: If they equal each other, then that must mean that the exponents equal. Therefore, we can draw out the conclusion that x+2=9, which is x=7

Answer:

The point is (8,2)

Step-by-step explanation:

Is this a square or rectangle or rhombus, etc.? Yes, because all the lines are all parallel.

Are AB and FG are parallel to each other right? Yes, so that means whatever you do to F will happen to G and we can start on A, it goes 6 down, then two to the right.

Since all lines are parallel how many steps we do on A to get F, we have to do to B to get G. So, (8,2).

Answer:

17 t-shirts sold

Step-by-step explanation:

If we assume that we don't need t find the number of hats, then we can say that the profit from -tshirts would be $125 minus 40 or $85

Then we can write the following equation of x is the number of t-shirts:

5x = 85

If we solve by diving both sides of the equation by 5:

5x/5 = 85/5

x = 17 t-shirts sold

Answer: Yes, and the numbers are 4, 36, and 9

Step-by-step explanation:

Yes, because it x=4, y=36, and z=9 then 4 * 36=144, 144=12*12 4*9=36, 36=6*6, and 9*36=324, 324=18*18. As you can see they are all perfect squares and 4, 36, and 9 are all perfect sqaures too.

Answer:

The ladder has 20 steps

Step-by-step explanation:

10 is the direct middle if you go down 4 that is 6, if you go back up 7 you get 13 and if you go back down 13 and you are on the first step 13-13 is 0, so the ladder has 20 steps.

Step-by-step explanation:

Answer:

a) i) The probability depends on the total number of counters not on the number of colors.

  ii) There are 10 number of counters not 4

b) [tex]\dfrac{3}{10}[/tex]

Step-by-step explanation:

Given that:

Total number of counters in a bag = 10

Number of red counters = 4

Number of green counters = 3

Number of pink counters = 2

Number of blue counters = 1

a) Ella writes: "There are four colors, so the probability of selecting a green is [tex]\frac{1}4 + \frac{1}4 = \frac{2}4[/tex] , so the probability is [tex]\frac{1}2[/tex]"

Ella has considered the total type of counters here, which is 4.

But Ella must have considered total number of counters which is 10.

  i) The probability depends on the total number of counters not on the number of colors.

  ii) There are 10 number of counters not 4

b) There are 4 colors in the bag.

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

To select 2 counters of the same color:

[tex]P(2\ red) = \dfrac{4}{10}\times \dfrac{4}{10} = \dfrac{16}{100}[/tex]

[tex]P(2\ green) = \dfrac{3}{10}\times \dfrac{3}{10} = \dfrac{9}{100}[/tex]

[tex]P(2\ pink) = \dfrac{2}{10}\times \dfrac{2}{10} = \dfrac{4}{100}[/tex]

[tex]P(2\ blue) = \dfrac{1}{10}\times \dfrac{1}{10} = \dfrac{1}{100}[/tex]

The required probability will be the sum of all 4 above probabilities:

[tex]P(2\ of\ same\ color) = \dfrac{30}{100} = \bold{\dfrac{3}{10} }[/tex]

Answer:

g = 1/2

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

9 + 3.5g = 11 - 0.5g

Step 2: Solve for g

Step 3: Check

Plug in g into the original equation to verify it's a solution.

Here we see that 10.75 does indeed equal 10.75.

∴ g = 1/2 is a solution of the equation.

Answer: g= 0.5

Step-by-step explanation:

Add

3.5g and 0.5g. to get

9+4g=11

then subtract 9 from the 11 and you should get 4g=2.

then divide 4 from 2 and you should get the answer of 2/4.

simplify it and you should get the answer g=0.5
