Expand the following:
a) x(x + 6)
b) x(5x - 1)
c) 3x(6x + 5)
d) 4x(2x – 3y)
Answer:
a) x(x + 6) = x · x + x · 6 = x² + 6x
b) x(5x - 1) = x · 5x - x · 1 = 5x² - x
c) 3x(6x + 5) = 3x · 6x + 3x · 5 = 18x² + 15x
d) 4x(2x – 3y) = 4x · 2x - 4x · 3y = 8x²-12xy

Jacob decided to start saving for college. After 3 months, he had saved $174. His friend Victoria was inspired to do the same. After 6 months, she had saved $360. If they are both saving money at a constant rate, how many more dollars per month does Victoria save than Jacob?
Answer:
$2 more.
Step-by-step explanation:
In this question, we have to find how much more money Victoria is saving.
We know that Jacob saved $174 in 3 months.
We also know that Victoria saved $360 in 6 months.
Lets find how much money they save per month:
Jacob:
174 ÷ 3 = 58
Victoria:
360 ÷ 6 = 60
Jacob is saving $58 per month and Victoria is saving $60 per month.
This means that Victoria is saving $2 more than Jacob per month.

Mrs.owens bought two candles for her dining room table. She paid with a $100 bill and received $32.16 in change. If sales tax is charged at a rate of 6% what was the price for one candle holder before taxes?
The price for one candle holder before taxes is $30.88.
What is a tax?It is an amount of money that a government requires people to pay according to their income, the value of their property, etc., and that is used to pay for the things done by the government.
The total payment including tax is $100.
The change received is $32.16.
The rate of sale tax is 6%.
The cost of one candle including tax is given by
(100 - 32.16) / 2 = 32.92
6% of a candle is given by
32.92 * 0.06 = 2.0352
The cost of one candle without tax is given by
32.92 - 2.0352 = 30.88

A certain insecticide kills 60% of all insects in laboratory experiments. A sample of 12 insects is exposed to the insecticide in a particular experiment. What is the probability that exactly 10 insects will die
Answer:
The probability that exactly 10 insects will die
P( X = 10 ) = 0.06385
Step-by-step explanation:
Step(i):-
Given a certain insecticide kills 60% of all insects in laboratory experiments
Given proportion p = 0.60
q = 1 - 0.60 = 0.40
Given sample size 'n' = 12
Step(ii):-
Let "X' be the random variable of binomial distribution
[tex]P(X=r) = n_{C_{r} } p^{r} q^{n-r}[/tex]
The probability that exactly 10 insects will die
[tex]P(X=10) = 12_{C_{10} } (0.60)^{10} (0.40)^{12-10}[/tex]
[tex]n_{C_{r} } = \frac{n!}{(n-r)!r!} = \frac{12!}{(12-10)!10!} = 66[/tex]
[tex]P(X=10) = 66 X (0.60)^{10} (0.40)^{2} = 0.06385[/tex]
Final answer:-
The probability that exactly 10 insects will die
P( X = 10 ) = 0.06385

Find the Value of “Y”.
Answer:
26
Step-by-step explanation:
7x - 28 = 5x + 12 and 5x + 12 + y = 180
The angle (7y - 28) and angle y are supplementary angles which means their sum is 180°
7y - 28 + y = 180 add like terms
8y - 28 = 180 add 28 to both sides
8y = 208 divide both sides by 8
y = 26

The price of a telephone is 200$ in shop A and 240$ in shop B. If you get 15% discount
shop B, where would you buy the telephone (both shops are next to each other
Answer: Shop A
15% of 240 is 36 and 240-36 is 204 so shop B is more expensive.
The price of a telephone at shop A is less than the price of a telephone at shop B. Then the telephone is bought from shop A.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The price of a telephone is $200 in shop A and $240 in shop B. If you get a 15% discount shop B.
The price of the telephone after the discount at shop B will be given as,
⇒ (1 - 0.15) x $240
⇒ 0.85 x $240
⇒ $204
The price of a telephone at shop A is less than the price of a telephone at shop B. Then the telephone is bought from shop A.

What percentage of the shape is purple?
Write your answer using a percent sign (%).

Okay, we see that there are 10 pieces in the circle - thus, it is our denominator. Next, we see that 9 out of them are coloured in. Therefore, the fraction is 9/10. To express our answer as a percent, we need to divide 9 and 10 to get 0.9. Then, we multiply 0.9 by 100 to get 90%. As a result, your answer is 90%.
The percentage of the shape that is purple is approximately 90%.
To find the percentage of the shape that is purple, we need to calculate the proportion of purple pieces out of the total number of pieces and express it as a percentage.
Given that there are 10 pieces in total and 9 of them are colored in, we can calculate the percentage as follows:
Percentage of purple pieces = (Number of purple pieces / Total number of pieces) × 100
Percentage of purple pieces = (9 / 10) × 100
Percentage of purple pieces = 0.9 × 100
Percentage of purple pieces = 90%
Therefore, the percentage of the shape that is purple is approximately 90%.
