Answer:

5/25

Step-by-step explanation:

khan academy

Answer:

5/25

Step-by-step explanation:

The number 3.44 is 40% per cent of the number 8.6.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the number 3.44 is some percentage of the number 8.6. The percentage of the number will be calculated as:-

x% of 8.66 = 3.44

( x / 100 ) x 8.66 = 3.44

x = ( 3.44 x 100 ) / 8.66

x = 40%

Therefore, the number 3.44 is 40% per cent of the number 8.6.

For this case we have the following kinematic equation that models the problem:

h (t) = (1/2) * (- 9.8) * t ^ 2 + 12 * t + 2

Rewriting we have:

h (t) = -4.9 * t ^ 2 + 12 * t + 2

When the ball hits the ground we have:

-4.9 * t ^ 2 + 12 * t + 2 = 0

Solving the polynomial we have:

t1 = -0.16

t2 = 2.61

We ignore the negative root because it is time.

Answer: It will take the ball to hit the ground about:

t = 2.61 sec

Answer:

Just substitute, and the simplified form is 1

Step-by-step explanation:

Substitute the values needed into the original equation. For example, if n=1

t(1)=15-2.5(1)=15-2.5=12.5. Or, if tn+1 substitute f(tn+1)=15-2.5(tn+1) and simplify.

tn+1-tn in its simplest form is just 1, as tn and -tn cancel out to leave 1.

Answer:

3,125

Step-by-step explanation:

1. This sequence is similar to the Fibonacci sequence, where you add the two terms to get the next term and so on. (e.g. 1, 1, 2, 3, 5, 8, 13)

2. However, this differs from the Fibonacci sequence because instead of adding, we're multiplying. 1 x 5 = 5, 5 x 5 = 25, 5 x 25 = 125. Given this sequence, we have to multiply 25 by 125 next, and the product of that expression is 3,125!

Answer:

40%

Step-by-step explanation:

So, there are 60 students for B. So, what I did was add all the students to get 150. Then I divided 60 by 150 (60/150) to get 0.4. 0.4 * 100 is 40 which is the percent. Hope this helps.

Answer:

A. Probability of Russell = 12/37 or 32.4% (Rounding to the next tenth)

B. Probability of Peter = 5/74 or 6.8% (Rounding to the next tenth)

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

              Guard Forward Center Totals

Over 6 feet 25     30        30        85

Under 6 feet 130 120      35        285

Totals           155 150      65        370

2. Russell is 5'9". What is the probability he is a forward?

Probability = Number of forwards under 6 feet/Total number of players

Probability = 120/370

Probability = 12/37 or 32.4% (Rounding to the next tenth)

3. Peter is 6'2". What is the probability he is a guard?

Probability = Number of guards over 6 feet/Total number of players

Probability = 25/370

Probability = 5/74 or 6.8% (Rounding to the next tenth)

Answer:

Equivalent expressions are expressions that have the same value. Writing equivalent expressions can make them easier to work with and solve.

Sometimes when you are writing equivalent expressions, you will need to use the distributive property. Multiply a number outside of parentheses by each number inside the parentheses.

Look at the steps for 3(2+4t).

3(2+4t)  Multiply 3 by each addend.

3(2)+3(4t) To multiply 3 and 4t, multiply 3 and 4. The variable stays the same. So, 3(4t)=12t.

6+12t

So, 3(2+4t) and 6+12t are equivalent expressions.

Step-by-step explanation:

Answer:

Enter the equations.

Multiply each equation by a number to get the lowest common multiple for one of the variables.

Add or subtract the two equations to eliminate that variable .

Substitute that variable into one of the equations and solve for the other variable.

Let aₙ be the n-th term of the A.P.

Then for some fixed number d,

[tex]a_{844} = a_{843} + d[/tex]

[tex]a_{844} = (a_{842} + d) + d = a_{842} + 2d[/tex]

[tex]a_{844} = (a_{841} + d) + 2d = a_{841} + 3d[/tex]

and so on.

Notice how on the right side, the subscript of a and the coefficient of d always add up to 844. Follow this pattern all the way down to a₁₉ to get

[tex]a_{844} = a_{19} + 825d[/tex]

We're told that a₁₉ = 844 and a₈₄₄ = 19. Solve for d :

19 = 844 + 825d

825d = -825

d = -1

We can also write aₙ in terms of an arbitrary k-th term, aₖ, using the pattern from before:

[tex]a_n = a_k + (n - k) d[/tex]

Suppose aₖ = 0 for some value of k. Pick any known value of aₙ, replace d = -1, and solve for k :

a₈₄₄ = 0 + (844 - k) • (-1)

19 = k - 844

k = 863

So, a₈₆₃ = 0.

Answer: The mixed number 5  7/9

We can write the mixed number as 5 & 7/9 to better separate the whole part (5) from the fractional part (7/9)

==================================================

Explanation:

Use this formula

[tex]a \frac{b}{c} = \frac{a*c + b}{c}[/tex]

to convert from a mixed number to an improper fraction.

Here are the steps in converting 5 & 1/3

[tex]a \frac{b}{c} = \frac{a*c+b}{c}\\\\5 \frac{1}{3} = \frac{5*3+1}{3}\\\\5 \frac{1}{3} = \frac{16}{3}\\\\[/tex]

Through similar steps you should also have

[tex]4 \frac{5}{9} = \frac{41}{9}\\\\6 \frac{5}{9} = \frac{59}{9}\\\\[/tex]

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

Let's add the amounts needed for the family room and the living room.

[tex]\frac{41}{9}+\frac{59}{9}\\\\\frac{41+59}{9}\\\\\frac{100}{9}\\\\[/tex]

Subtract off the amount the painter already has

[tex]\frac{100}{9} - \frac{16}{3}\\\\\frac{100}{9} - \frac{3*16}{3*3}\\\\\frac{100}{9} - \frac{48}{9}\\\\\frac{100-48}{9}\\\\\frac{52}{9}\\\\[/tex]

This improper fraction is the number of gallons of paint that's missing, i.e. the amount the painter needs to buy.

Converting it to a mixed number gets us:

[tex]\frac{52}{9}=\frac{45+7}{9}\\\\\frac{52}{9}=\frac{45}{9}+\frac{7}{9}\\\\\frac{52}{9}=5+\frac{7}{9}\\\\\frac{52}{9}=5\frac{7}{9}\\\\[/tex]

Note that 52/9 leads to a quotient of 5 and a remainder of 7. The 5 and 7 match with 5 & 7/9

The painter needs to buy 5 full gallons, plus another 7/9 of a gallon. Or we can state it as him needing 5 & 7/9 gallons of paint.
