The price of an item has been reduced by 35% . The original price was $60. What is the price of the item now?

Answer: 19.56z - 9

Step-by-step explanation: Hello!  Here are the steps to solve this problem:

14.33z - 3 - (6 - 5.23z).  

Firstly, you have to use the distributive property and distribute -1 to the parentheses using PEMDAS, Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

14.33z - 3 + -1(6 - 5.23z)
14.33z - 3 + (-6 + 5.23z)
14.33z + (-3) + (-6) + (5.23z)
14.33z + (5.23z) + (-3) + (-6)
(14.33z + 5.23z) + (-3 - 6)
19.56z + (-3 - 6)

19.56z + (-9)
19.56z - 9.

Answer: $115

Step-by-step explanation:  

92 is the price after a 20% discount, so it is 80% of the original value.

So, solve, 92÷0.80=115

So the original price was $115

According to the concept of average it will take 3 days in order to get a "no homework" day.

The term called average in math is defined as the number you get when you add two or more figures together and then divide the total by the number of figures you added.

Here we know that Mrs. Bready has a large bag filled with red and green cards. She tells the class that 15% of the cards are red and 85% are green.

And here we need to determine the average number of days that it will take in order to get a "no homework" day based on these 5 trials,

Then the following calculation must be performed as,

=> 0.85 x 0.85 x 0.85 x 0.85 x 0.85 = X

=>  x = 0.4437

Hence it will take 4.2 days in order to get a "no homework" day.

Here we have already know that the first trial is carried out then we have to subtract it from the total number then we get,

=> 4.2 - 1 = 3.2

When we round off the value then we get 3.

Therefore, option (b) is correct.

Answer:

I believe the answer is 273

Step-by-step explanation:

The unshaded part would be an area of 273 because the base is 26 and the height 21. You times that and divide it by 2.

Along with that times the whole rectangle (26 x 21 = 546)

Subtract 546 and 273 and get 273.

The probability that Sam's first upgrade will occur after the third flight = 0.729

Let m represents the number of flights Sam must take in order to receive his first upgrade.

To find the probability that Sam's first upgrade will occur after the third flight.

i.e., to find P(m ≥ 4)

Here,  0.10 probability that a coach-class ticket holder who flies frequently will be upgraded to first class on any flight.

p = 0.10

q = 1 - p

q = 0.90

P(m ≥ 4) = 1 - P(m ≤ 3)

P(m ≥ 4) = 1 - [P(m = 1) + P(m = 2) + P(m = 3)]

P(m ≥ 4) = 1 - [0.1 + (0.9 × 0.1) + (0.9² × 0.1)]

P(m ≥ 4) = 1 - (0.1 + 0.09 + 0.081)

P(m ≥ 4) = 0.729

Answer:

Yes. The two parallelograms are similar.

Step-by-step explanation:

Similarity:

     Two parallelograms are said to be similar when the corresponding sides are in the same ratio.

  [tex]\sf \dfrac{WX}{AB}= \dfrac{3}{2}\\\\\dfrac{XY}{BC}=\dfrac{9}{6} = \dfrac{9 \div 3}{6 \div 3}\\\\[/tex]

        [tex]\sf = \dfrac{3}{2}[/tex]

During the 1950s in the United States, married women who worked outside the home faced social pressures to stay at home with their children, but despite these pressures, the number of married women working outside the home increased throughout the decade. By the end of the 1950s, married women who worked outside the home accounted for nearly one-third of all married women.

It is worth mentioning that during that time, there were many societal expectations that women should be homemakers, and it was not as common for married women to work outside the home as it is today. Additionally, discrimination, lack of opportunities and lower wages for women further decreased the number of working women. However, during the 50s women started to participate more in the workforce, and that trend continued to increase in the following decades.

The interpret of P(0) is 0 and P(250) = 132.58. The domain of P is [0, ∞]

The population of Sasquatch in Portage County can be modeled by the function P(t) = 140t/(t + 14) where t represents the number of years since 1803.

We have to interpret P(0).

To interpret P(0) we put t = 0 in the function then solve the function.

The function is:

P(t) = 140t/(t + 14)

Putting t = 0

P(0) = (140 × 0)/(0 + 14)

P(0) = 0/14

P(0) = 0

Now we interpret P(250) by putting t = 250.

P(250) = (140 × 250)/(250 + 14)

P(250) = 35,000/264

P(250) = 132.58

The domain of the time cannot be negative. So the domain of P is [0, ∞].

The quotient is x³-3x²-3x+9 and the remainder is -33.

Synthetic division is a method used to perform the division operation on polynomials when the divisor is a linear factor.

When we divide a polynomial p(x) by a linear factor (x - a) (which is a polynomial of degree 1), Q(x) is the quotient polynomial and R is the remainder.

p(x)/q(x) = p(x)/(x- a) = Quotient + (Remainder/(x - a))

p(x)/(x - a) = Q(x) + (R/(x - a))

(A) The British literature class is most likely larger, because the standard deviation is lower.

A high standard deviation suggests that the observed data is very variable around the mean. This suggests that the observed data is widely dispersed. Instead, a modest or low standard deviation would suggest that the majority of the observed data is closely packed around the mean.

The standard deviation measures the degree of dispersion of a set of data. Each data point is compared to the average of all the data points, and standard deviation gives a determined value that indicates whether the data points are clustered together or dispersed.

Hence, when standard deviation is lower the class is most likely to be larger in number.

2x² +10x.

step 1: The first side's length is (x+ 5) metres, while the second side's breadth is (2x+ 1) metres.

Now, the RECTANGLE'S PERIMETER = 2 (LENGTH + WIDTH).

Here, perimeter is equal to 2 ((x+ 5) m + (2x + 1) m) or 2 (x + 5 + 2x +1) = 2(3x + 4) = 6x + 8

Therefore, the rectangle's perimeter is equal to (6 x + 8) metres.

step 2:

Area of a rectangle equals length times breadth

Given:

Size = x+5

Thickness = 2x+1

Area of rectangle = length breadth = (x+5) (2x+1) = 2x (x+5) (2x+1) =2x2+5+4x+1 =2x2+10x, according to the query.
