Shalnov [3]

Answer:

Step-by-step explanation:

This is asking what is A

Formula A squared + B squared = C squared

A=x

B=8

C=20

X^2+ 8^2=20^2

8 squared is 64

20 squared is 400

400-64 is 336

X*X=336 find the square root of 336 =18.3

CHECK

18.3*18.3+ 8*8=398.89 which is super close to 400

Solve each problem by forming a pair of simultaneous equations:

Diano4ka-milaya [45]

Answer:

5.5, 9.5

Step-by-step explanation:

Let x and y be the numbers

x+y = 15

x-y = 4

Add the two equations together to eliminate y

x+y = 15

x-y = 4

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

2x = 19

Divide by 2

2x/2 =19/2

x = 9.5

Now find y

x+y = 15

9.5+y = 15

Subtract 9.5

x = 15-9.5

x =5.5

If you bought a stock last year for a price of $36, and it has gone down 16.6% since then, how much is the stock worth now, to t

Pepsi [2]

Answer:

The stock is now worth of $30.024.

Step-by-step explanation:

Here, the price of the stock last year =$36

The percentage down in the price of stock in a year = 16.6 %

Now, 16.6% of the value of stock $36 = $\frac{16.6}{100} \times 36= 5.976$

⇒16.6% of $36 = $ 5.976

Now, the Current Worth of Stock = Stock Value last year - Decrease in the stock price

= $36 - $ 5.976 = $30.024

Hence, the stock is now worth of $30.024.

John the car salesman makes a commission on selling cars, as a percentage of the price, which

Bess [88]

Answer:

<u>John's commission percentage on new cars is x and his commission percentage on used cars is 1.5x, therefore, John's commission percentage on new cars is 2% and his commission percentage on used cars is 3%.</u>

Step-by-step explanation:

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

John's commission percentage on new cars = x

John's commission percentage on used cars = x + 50%x (His commission on used cars is 50% more than on new cars)

Sales on new cars = $80,000

Sales on used cars = $50,000

John's commission check = $3,100

2. If x represents the commission percentage on new cars, express the commission percentage on used cars in terms of x.

John's commission percentage on new cars = x

John's commission percentage on used cars = x + 50%x = 1.5x

Now we can solve for x, this way:

80,000x + 50,000 * 1.5x = 3,100

80,000x + 75,000x = 3,100

155,000x = 3,100

x = 3,100/155,000

x = 0.02 = 2% ⇒ 1.5x = 3%

<u>John's commission percentage on new cars is 2% and his commission percentage on used cars is 3%</u>

a spinner has 6 equal-sized sections numbered 1,1,2,2,3and 4. what is the sample space for the spinner, and what is the probabil

Nezavi [6.7K]

Answer:

S={1, 1, 2, 2, 3, 4}

Probability of spinning a 1 = 1 in 3 or 33%

Step-by-step explanation:

The sample space is the set of all possible outcomes in an experiment. The outcomes here are the numbers in each section of the spinner: 1, 1, 2, 2, 3, 4. The sample space is:

S={1, 1, 2, 2, 3, 4}

Two out of six possible outcomes are "1s", therefore the probability of spinnin a 1 is:

$P(1)=\frac{2}{6}=\frac{1}{3}=33.33\%$

The probability of spinning a 1 is 1 in 3 or 33%.
