Step-by-step explanation:
3(x - 4) + 2(x + 5) = 3*x - 3*4 + 2*x + 2*5
= 3x - 12 + 2x + 10
= 3x + 2x - 12 + 10 {Combine like terms}
= 5x - 2

In a game, a player has to guess a 3-digit code in an attempt to unlock a trunk containing a prize. If the digits are to be chosen from the integers between 0 and 9 and they can be repeated, what is the probability that the player guesses the correct code on the first try?
Answer:
I think it will be 3/9=1/3
The probability that the player guesses the correct code on the first try is 0.001 or 0.1%.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
In a game, a player has to guess a 3-digit code in an attempt to unlock a trunk containing a prize.
If the digits are to be chosen from the integers between 0 and 9 and they can be repeated.
The total number of outcomes will be
Total outcomes = 10³ = 1000
The player guesses the correct code on the first try. Then the favorable event will be
Favorable event = 1
Then the probability will be
[tex]\rm P = \dfrac{1}{1000}\\\\P = 0.001\\\\P = 0.1 \%[/tex]

Use a calculator to solve for θ in the given interval. Cot θ= 0.7615, for 0 < θ < 2 pi
θ = 52.71° or 232.71°
In radians
θ = 0.2928π rad or 1.2928π rad
That is,
θ = 0.92 rad or 4.06 rad
Step-by-step explanation:
Cot θ = 0.7615 for 0 ≤ θ ≤ 2π
Note that Cot θ = (1/tan θ)
(1/tan θ) = 0 7615
tan θ = (1/0.7615) = 1.3132
θ = tan⁻¹ (1.3132) = 52.71°
But, note that tan is also positive in the 3rd quadrant, hence,
θ is also equal to 180° + 52.71° = 232.71°
θ = 52.71° or 232.71°
We now convert to radians
360° = 2π
52.71° = (52.71 × 2π)/360 = 0.2928π = 0.92 radian
232.71° = (232.71 × 2π)/360 = 1.2928π = 4.06 radians

Kim bought x pairs of shoes for $45 each and y pairs of socks for $4 each. She spent $159 in all. Which equation represents this situation? A. 45 + x + 4 + y = 159 B. 45 + 4 + xy = 159 C. 45x + 4y = 159 D. 4x + 45y = 159
Answer:
C
Step-by-step explanation:
The number of shoes times the cost plus the number of socks times the cost is equal to 159
3 baguettes and 2 rolls=£3
1 baguettes and 4 rolls=£2
How much does each item cost on its own?
Answer:
baguettes are b = $0.80
rolls are r = $0.30
Step-by-step explanation:
1b + 4r = 2
3b + 2r = 3 step 1 when we need to balance and make one the same
6b + 4r = 6 step 2 when both equations must have 1 same value ie) 4r we take 2r and x2 to all values on that same equation.
6b + 4r = 6
-
1b + 4r = 2 step 3 when both equations show add we subtract them
5b = 4
b = 4/5
b = 0.8 b = 0.8 = 4/5 step 4 when we find x we plug in for x in this case we found b and plug in for b
1(0.8) + 4r = 2
0.8 + 4r = 2
4r = 2 - 0.8
4r = 1.2
r = 1.2 /4
r = 0.3
Find the missing amount)
Original:_______
New: 260 gallons
%increase: 30%
(not multiple choice)
Answer: 182 gallons
find 30% of 260 by multiplying 260 by 30%
260 x .3 = 78
30% of 260 = 78
Subtract 78 from 260 to get original amount
260 - 78 = 182
Original is 182 gallons
ps. this is an actual impossible question because you need to know the original amount to find what 30% of it is. What i found was a 30% decrease of 260 not a 30% increase of the original. With that being said I think this is what you want?
Answer:
Original = 200 gallons
Step-by-step explanation:
Original: x
New: 260
Percent Increase: 30%
x = 100%
New = 100% + 30%
260 = 130%
To find, original we do:
260/130 * 100 =
2 * 100 = 200

Answer:
B
Step-by-step explanation:
To solve this problem we need to use order of operations or GEMDAS
First the Groupings which is the ()
Next is the Exponents,
3^6 = 729
y^-5 = y^-5 (Since it is a variable there is really nothing we can do about it)
Next is the other set of () outside our fraction (the ^2)
(Note: We really shouldn't have solved the exponents but just have placed them there but I just wanted to show you how that would look like.)
(3^6)^2 = 3^12
(y^-5)^2 = y^10
Meaning, the answer would be B
Hope this helps (Make sure to check it though)
Answer:
Answer B is correct
Step-by-step explanation:
Before, solving this let us get to know some points.
⇒ [tex](a^{x}) ^{y} = a^{xy}[/tex]
⇒ [tex]a^{x} *a^{y} =a^{x+y}[/tex]
⇒ [tex]\frac{a^{x} }{a^{y} } =a^{x-y}[/tex]
⇒ [tex]a^{-x} =\frac{1}{a^{x} }[/tex]
⇒ [tex]\frac{1}{a^{-x} } =a^{x}[/tex]
Let us solve the question now.
( 3⁶ ÷ y⁻⁵)²
3⁽ ⁶ ˣ ² ⁾ ÷ y ⁽ ⁻⁵ ˣ ²⁾
3¹² ÷ y⁻¹⁰
3¹² ÷ [tex]\frac{1}{y^{-10} }[/tex]
3¹² × y¹⁰
Therefore, Answer B is correct.
Charlie is shopping for a jacket that he likes. The jacket, regularly priced at $200, is on sale at Clothes Are Us for $150. Jacket World is offering a 25% discount on the same jacket that regularly sells for $190 at that store. Which statements are correct for this situation?
A) Jacket World's price is $150.00
B) Jacket World has the better deal.
C) Clothes Are Us has the better deal.
D) Both stores are offering a 25% discount on the jacket.
E) The difference in the sale prices at the two stores is $7.50.
List all that are correct
Choice B) Jacket world has the better deal.
Choice D) Both stores are offering a 25% discount on the jacket.
Choice E) The difference in sale prices at the two stores is $7.50
===========================================================
Explanation:
25% = 0.25
25% of $190 = 0.25*190 = 47.50
190 - 47.50 = 142.5
This indicates the price at Jacket World is $142.5 instead of $150
Therefore, choice A is false.
---------------------
Choice B on the other hand is true because $142.50 at Jacket World is a lower price compared to $150 at Clothes Are Us. Jacket World has the better deal.
---------------------
Because choice B was shown to be true, there's no way choice C can be true as well. Otherwise, we'd have a contradiction. So we can rule out choice C.
---------------------
Let's find the percentage discount for Clothes Are Us.
The original price is $200 and its sale price is $150. So you save 200-150 = 50 dollars.
Divide that over the original price to find the discount: 50/200 = 0.25 = 25%
Therefore, Clothes Are Us has the same discount percentage as Jacket World. Both have a 25% discount. Choice D is true.
---------------------
Comparing the two sale prices of $150 (Clothes Are Us) and $142.50 (Jacket World), the difference in price is 150-142.50 = 7.50; this means choice E is a true statement.

Answer:
See Below
Step-by-step explanation:
Point A (0,0)
Point B (3,2)
Point C (9,6)
b. x values from A to B: 0 to 3
x values from B to C: 3 to 9
No, AB has a change of 3 and BC has a change of 6 in x
c. y values from A to B: 0 to 2
y values from B to C: 2 to 6
No, AB has a change of 2 and BC has a change of 4 in y
d. Calculate Slope: [tex]\frac{y{2}-y{1}}{x{2}-x{1}}[/tex]
AB (2-0/3-0) = 2/3
BC (6-2/9-3) = 4/6 = 2/3 simplified
Thus, AB has the same ratio of change as BC
