Answer: they would have to win 22/40 games

Step-by-step explanation:

22 divided by 40 is 0.55 or 55%

Answer:

x = 12 (I took the FLVS assignment for 04.04, and I'll show you guys how to do this!)

Step-by-step explanation:

The team has completed 28 matches so far and has won 10 of them.

The current success rate is:

[tex]r=\frac{10}{28} *1.00=.35714[/tex]

(1.00 = 100% and .35714 = 35.714%)

We need the success rate to be 55%

Then the team must win a number of "x" matches, so:

[tex]r=\frac{10+x}{28+x} =0.55[/tex]

Now we solve the equation for x:

[tex]\frac{10+x}{28+x} =0.55[/tex]

[tex]10+x=0.55(28+x)[/tex](distributive property here!)

[tex]10+x=15.4+0.55x[/tex]

Now, move the 0.55x to the other side by subtracting it from both sides:

[tex]10+x-0.55x=15.4[/tex]

And move the 10 by doing the same thing (subtracting from both sides):

[tex]x-0.55x=15.4-10[/tex]

[tex]0.45x=5.4[/tex]

(You might ask: 15.4 - 10 = 5.4, but how do you get 0.45x out of x - 0.55x? Use Quick Math, and you should get the answer!)

[tex]x=\frac{5.4}{0.45}[/tex]

[tex]x = 12[/tex]

So, by following these steps, x = 12 is your answer!

The team must win 12 matches to have a success rate of 55%.

Hope this helps! Have a wonderful day!

Answer: the train traveled 43km southwards

Step-by-step explanation:

First, let's define.

North as the positive y-axis.

East as the positive x-axis.

And the initial position of the train is (0, 0).

Now, we know that:

"A train first travels east for 20 kilometers."

The new position will be:

(0, 0) + (20km, 0) = (20km , 0)

"Then it turns north and travels for 43 kilometers."

The new position will be:

(20km, 0) + (0, 43km) = (20km, 43km)

"Next it goes west for 20 kilometers."

If East if the positive x-axis, then West is the negative x-axis.

The new position of the train will be:

(20km, 43km) + (-20km, 0) = (0, 43km)

Then it travels south for an unknown number of kilometers, such that the final position is the same as the initial position, then if the train goes X kilometers to the south (and because North is the positive y-axis, South will be the negative y-axis), we have:

(0, 43km) + (0, -X) = (0, 0)

(0, 43km - X) = (0, 0)

Then we must have that:

43km - X = 0

43km = X

This means that the train traveled 43km southwards.

We are given:

Money on the fifth day (a₅) = $80

Money on day 21 (a₂₁) = $160

To Find:

Money in the bank on the first day (a₁) = ?

Money being added to the account per day (d) = ?

Money in the bank on day 30 (a₃₀) = ?

__________________________________________________________

Finding the money on day one and the money added:

Solving for equations

Since we are adding a constant amount to our account every day, the amount of money in the bank can be represented by an AP

We know that the formula for the nth term of an AP is:

aₙ = a₁ + (n-1)d

So, we can write the amount of money on day 5 as:

a₅ = a₁ + (5-1)d

a₅ = a₁ + 4d

80 = a₁+  4d                        [We are given that a₅ = 80]

We are also given the amount of money on day 21:

a₂₁ = $160

Money on day 21 can be rewritten as:

a₂₁ = a₁ + (21-1)d

160 = a₁ + 20d                  [Since a₂₁ = 160]

Solving the equations:

Now we have 2 equations. We will now solve them to get the values of a₁ and d

160 = a₁ + 20d ----------------------(1)

80 = a₁ + 4d--------------------------(2)

From equation (2), we can say that:

a₁ = 80 - 4d              [subtracting 4d from both sides]

Now, we will use this value of a₁ in the equation (1):

160 = a₁ + 20d

160 = (80-4d) + 20d

160 = 80 + 16d

80 = 16d             [subtracting 80 from both sides]

d = 5                   [dividing both sides by 16]

Now that we know the value of d, we can use it in any of the 2 equations:

80 = a₁ + 4d

80 = a₁ + 4(5)              [since d=5]

80 = a₁ + 20

a₁ = 60                        [subtracting 20 from both sides]

Now, we know the values of the initial amount of money and the money added to the account everyday

Initial money in the bank = $60

Money added everyday = $5

__________________________________________________________

Money in day 30:

We will use the AP formula to find the value of money on day 30

a₃₀ = a₁ + (30-1)d

We know that a₁ = $60 , d = $5

a₃₀ = 60 + 29(5)

a₃₀ = 60 + 145

a₃₀ = $205

Money on day 30 = $205

Answer:

started with $55

adds $5 each day

$205 on the 30th day

Step-by-step explanation:

21-5 = 16

160-80 = 80

80 divided by 16 = 5

5 * 5 = 25

80 - 25 = 55

9 * 5 = 45

160 + 45 = 205

Step-by-step explanation:

Answer:

69

Step-by-step explanation:

69x 9= 621

Step-by-step explanation:

-3^2 / 9^6

-3^2 / 3^2

(9 divided by 3 = 3 and 6 divided by 3 = 2)

It would now be -1 because a negative divided by a positive gives a negative.

Answer:

7 feet long

Step-by-step explanation:

This set up will give a right angle triangle where;

Length of the ladder is the hypotenuse = x

The distance of the ladder to the house is the adjacent = 3 feet

Angle of elevation theta = 72 degrees

Using the CAH in trigonometry identity;

cos theta = adjacent/hypotenuse

cos 72 = 3/hyp

hyp = 3/cos72

hyp = 3/0.4258

hyp = 7.05 feet

Hence the ladder is approximately 7 feet long

Answer:

x = 6, y = -113

Step-by-step explanation:

10x - y = 53 --- Equation 1

y = [tex]\frac{-13x+92}{2}[/tex] --- Equation 2

I will be using the substitution method.

Substitute y = [tex]\frac{-13x+92}{2}[/tex] into Equation 1:

10x - y = 53

10x - ([tex]\frac{-13x+92}{2}[/tex]) = 53

I want to make the denominators on the left side of the equation the same, so I will multiply 10x by 2 so that I can get a fraction.

[tex]\frac{20x}{2}[/tex] - ([tex]\frac{-13x+92}{2}[/tex]) = 53

Now that their denominators are both 2, I can combine the numerators under the same denominator.

[tex]\frac{20x-(-13x+92)}{2}[/tex] = 53

Two minuses, one outside a bracket and one inside makes a plus. One plus and one minus make a minus.

[tex]\frac{20x+13x-92}{2}[/tex] = 53

Evaluate like terms.

[tex]\frac{33x-92}{2}[/tex] = 53

Shift the (÷2) over to the right side and turn into (×2).

33x - 92 = 53 × 2

               = 106

Shift the (-92) over to the right side and turn into (+92).

33x = 106 + 92

      = 198

Find x.

x = 198 ÷ 33

x = 6

Substitute x = 6 into Equation 1:

10x - y = 53

10(-6) - y = 53

Evaluate.

-60 - y = 53

Shift the (-60) over to the right side and turn into (+60).

-y = 53 + 60

   = 113

Find y.

y = -113
