The axis of symmetry of a parabola is x=4.6. It crosses the x -axis at (0.6,0). What is the x -coordinate of the other point where the parabola crosses the x -axis?

Answers

Answer 1
Answer: keeping in mind that the vertex of a parabola is halfway between the x-intercepts, if a point is a 0.6, and the vertex is at 4.6, that's just 4 units over to the right, thus the other point will have to be 4 units further, check the picture below.

A pencil at a stationery store costs $1, and a pen costs $1.50. Shawn spent $12 at the store. He bought a total of 9 items. Which system of equations can be used to find the number of pencils (x) and pens (y) he bought?1.5x + y = 12
x = 9y

x + 1.5y = 12
x + y = 9

x + 9y = 12
x = 1.5y

9x + y = 12
x = 1.5y

Answers

The system of equations that represents the given statements is

x + 1.5y = 12

x + y = 9

Where x is the number of pencils and y is the number of pens that Shawn bought.

How to write an equation for a statement?

To write an equation:

  • Observe the variableterms from the given statement
  • Add/subtract required terms according to the word's 'total or difference' given in the statements
  • Multiply/divide required terms according to the words 'more or less given the statements
  • Equate with the respective values related to the variable term.

Calculation:

Given that,

A pencil at a stationery store costs - $1

and A pen costs - $1.50

Shawn spent $12 at the store. He bought a total of 9 items.

So,

Consider number of pencil = x and number of pens = y

Since he bought a total of 9 items, we can add the number of pencils and pens and equate the sum with 9

I.e., x + y = 9 ...(i)

We have cost for a single pencil and a single pen

So, to get the cost for the total number of pencils and pens that he bought, multiply the cost of a single one by the number of pencils and pens. I.e.,

1 × x and 1.50 × y

Since it is given that he spent $12 for both pencils and pens, we can write

x + 1.5 y = 12  ...(ii)

Thus, from equations (i) and (ii), the system we can write

x + 1.5 y = 12

x + y = 9

So, option 2 is the correctset of equations for the given system.

A candle manufacturer sells cylindrical candles in sets of three. Each candle in the set is a different size. The smallest candle has a radius of 0.5 inches and a height of 3 inches. The other two candles are scaled versions of the smallest, with scale factors of 2 and 3. How much wax is needed to create one set of candles?

Answers

so smalest has radius of 0.5 and heith of 3
multiply pi times 0.5^2 times 3=2.35619
so smallest is 2.36 in volume
I am not sure abouot the scale factors part

9/20 because you would get it as a decimal first and it would be .45 then put 100 at the end and then reduce and you end up with 9/20 
As a fraction it would be 45/100 and in simplest form it is 9/20

You randomly select a coin from a jar containing 30 coins: 8 pennies, 10 nickels, 7 dimes, and 5 quarters.What is the probability of:

selecting a penny?

selecting a nickel?

not selecting a dime?

selecting a dime or a quarter?

Answers

The probability of selecting a penny is 4/15

The probability of selecting a nickel is 1/3

The probability of selecting a dime is 7/30

The probability of selecting a dime or a quarter is 2/5

Probability

From the formula for probability,

P(A) = (Number\ of\ favourable\ outcomes\ to\ A)/(Total\ number\ of\ possible\ outcomes)

Total number of possible outcomes = 30

  • The probability of selecting a penny

P(penny) = (8)/(30)

P(penny) = (4)/(15)

The probability of selecting a penny is 4/15

  • The probability of selecting a nickel

P(nickel) = (10)/(30)

P(nickel) = (1)/(3)

The probability of selecting a nickel is 1/3

  • The probability of selecting a dime

P(dime) = (7)/(30)

The probability of selecting a dime is 7/30

  • The probability of selecting adime or a quarter

First, we will calculate the probability of selecting a quarter

P(quarter) = (5)/(30)

P(quarter) = (1)/(6)

Then, the probability of selecting a dime or a quarter is

P(dime \ or \ quarter) = (7)/(30)+ (1)/(6)

P(dime \ or \ quarter) = (7+5)/(30)

P(dime \ or \ quarter) = (12)/(30)

P(dime \ or \ quarter) = (2)/(5)

The probability of selecting a dime or a quarter is 2/5

Hence,

The probability of selecting a penny is 4/15

The probability of selecting a nickel is 1/3

The probability of selecting a dime is 7/30

The probability of selecting a dime or a quarter is 2/5
