Sara can read about 30 pages in 95 minutes.
What does per hour mean?To start, multiply the weekly hours by the number of weeks in a year to get the overall number of hours worked (52). Then subtract this amount from the annual pay. For instance, if a worker earns $50,000 annually and puts in 40 hours per week, their hourly rate would be $50,000/2,080 (40 x 52) = $24.04.
Accordion to question:First, we need to convert 95 minutes to hours by dividing by 60:
95 min ÷ 60 min/hour = 1.5833 hours (rounded to 4 decimal places)
Next, we can use the conversion factor to find the number of pages Sara can read in 1.5833 hours:
19 pages/hour x 1.5833 hours = 30.1391 pages
Rounding to the nearest whole number, Sara can read about 30 pages in 95 minutes.

The dot product a . b is -22
What is the dot productThe dot product, also known as scalar product or inner product, is a binary operation that takes two vectors and returns a scalar (single-valued) quantity. The dot product of two vectors is equal to the product of the magnitude (length) of the vectors and the cosine of the angle between them.
Given two vectors, A and B, the dot product is defined as:
A ∙ B = |A| * |B| * cos(θ)
where |A| and |B| are the magnitudes of vectors A and B, and θ is the angle between them.
a = <3, -2>
b = <-2, 8>
a . b = (3 * -2) + (-2 * 8)

Beth added 1 1/4
pounds of fruit to a fruit basket. Her son took 2 3/8 pounds
of fruit out of the basket. What was the total change in pounds of fruit in the
fruit basket?
Answer: To find the total change in pounds of fruit in the basket, we need to subtract the amount taken out from the amount added.
First, let's convert all the fractions to decimals:
1 1/4 = 1.25
2 3/8 = 2.375
Now, we can subtract:
1.25 - 2.375 = -1.125
So, the total change in the fruit basket was -1.125 pounds, meaning the basket had 1.125 pounds less fruit after the removal.

The first day after the autumn equinox that the solar panel generates 8400 kJ is approximately 39.2 days, or 0.107 radians, after the equinox.
To find the first day after the autumn equinox that the solar panel generates 8400 kJ, we need to solve the equation:
624sin(2π/365)t + 8736 = 8400
Simplifying the equation, we get:
sin(2π/365)t = 0.958
Taking the inverse sine of both sides, we get:
(2π/365)t = 1.296 or (2π/365)t = 3.846
Solving for t in each equation, we get:
t ≈ 78.97 or t ≈ 235.62
Since t is measured in radians, we need to convert it to days by dividing by 2π/365:
t ≈ 78.97 / (2π/365) ≈ 86.75 or t ≈ 235.62 / (2π/365) ≈ 256.73
Therefore, the first day after the autumn equinox that the solar panel generates 8400 kJ is either day 87 or day 257.

Step-by-step explanation:
ABC and ADE are similar triangles.
that means they have the same angles, and there is one scaling factor for all sides from one triangle to the other.
so, we see that AB = 2, AD = 2+1 = 3
the scaling factor f from AB to AD is then
AB × f = AD

f = 3/2
the same scaling factor now applies between BC and DE (= x).
BC × f = x

The barber cuts 61 haircuts in 4 days. Determine the rate for a ratio of the two different quantities.
61 over 65 haircuts per day
4 over 65 haircuts per day
4 over 61 haircuts per day
61 over 4 haircuts per day
Answer:
61 over 4 haircuts per day
What is a ratio?
A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.
A way to solve for the number of haircuts per day is to use this equation:
total number of haircuts ÷ number of days = haircuts per dayYou could also use this fraction:
[tex]\frac{total-number-of-haircuts}{number-of-days}[/tex]Inserting the numbers into the fraction::
[tex]\frac{61}{4}[/tex]Therefore, the rate for a ratio using the two different quantities is 61 over 4 haircuts per day.
the bakery made $600 Donuts they made 384 more Donuts than Bagels the bakery made 216 Bagels
The bakery made 384 donuts and 216 bagels
What is bakery?
A bakery is a business that produces and sells baked goods, such as bread, cakes, pastries, and cookies.
Let's use the variable "x" to represent the number of bagels made.
From the problem, we know that:
The number of donuts made is 384 more than the number of bagels made, so the number of donuts is x + 384.
The bakery made 216 bagels.
We also know that the bakery made a total of 600 donuts. So, we can set up an equation to represent the total number of pastries made:
x + 384 + 216 = 600
Simplifying and solving for x:
x + 600 = 600
x = 600 - 600 + 384
x = 384
So, the bakery made 384 + 216 = 600 pastries in total.
Therefore, the bakery made 384 donuts and 216 bagels.

Different values of the a coefficient result in different quadratic functions.
The vertex of the parabolas is halfway between the zeros, at x = -1.
y = a (-1 + 4) (-1 − 2)
y = -9a
So to find the value of a, divide the y-coordinate of the vertex by -9. For example, curve A has a vertex at (-1, -3), so the value of the a coefficient is -3 / -9 = ⅓.

A travel club can spend at most 10 nights in two cities on a trip. The club needs to reserve four rooms each night and wants to spend no more than 4200 on hotels and fuel. The estimated fuel cost is 200 can the club spend 3 nights in city a and 6 nights in city b? 7 nights in city a and 3 nights in city b? justify your answer using a system of linear equations
To solve this system, we must first determine the number of available rooms in each city, as well as the per-night cost of hotel rooms. Without that information, we can't tell if the club can spend three nights in city A and six nights in city B, or seven nights in city A and three nights in city B.
Let's start by defining the variables we'll need to solve this problem:
Assume that x is the number of nights spent in City A.
Let y represent the number of nights in City B.
To determine whether the club can spend three nights in city A and six nights in city B, or seven nights in city A and three nights in city B, we must first determine whether the total cost of hotels and fuel for each scenario is less than or equal to $4200.
Given that the estimated cost of fuel is $200, the cost of hotels must be less than or equal to $4000.
The following equations calculate the cost of hotels for each scenario:
3x + 6y = cost of hotels for spending 3 nights in city A and 6 nights in city B7x + 3y = cost of hotels for spending 7 nights in city A and 3 nights in city BWe also know that the club can only spend a total of 10 nights, so x + y must be less than or equal to 10.
Finally, we must ensure that the club can book four rooms each night. This means that the number of rooms required per night in each city is four times the number of nights. As a result, we must have:
4x ≤ number of available rooms in city A4y ≤ number of available rooms in city BWhen we combine all of these constraints, we get the following system of linear equations:
3x + 6y + 200 ≤ 4200 (cost constraint for spending 3 nights in city A and 6 nights in city B)
7x + 3y + 200 ≤ 4200 (cost constraint for spending 7 nights in city A and 3 nights in city B)
x + y ≤ 10 (total number of nights constraint) (total number of nights constraint)
A city with 4x available rooms (room constraint for city A)
4y rooms available in city B (room constraint for city B)
To solve this system, we must first determine the number of available rooms in each city as well as the cost of hotel rooms per night. We can't tell if the club can spend three nights in city A and six nights in city B, or seven nights in city A and three nights in city B, without that information.

Step-by-step explanation:
At the start of a party, a drink dispenser contains 912 quarts of iced tea. After the party only 7 cups of tea remain. How many cups of iced tea did people drink during the party?
Amount of iced-tea consumed during party was 92 cups, which is equivalent to 23 quarts. It's important to note difference between volume units such as cups and quarts, and the conversion factor between them.
To determine the number of cups of iced-tea that were consumed during the party, we need to subtract the amount that remained from the total amount that was in the drink dispenser at the start of the party.
One cup of iced tea is equal to 1/16 of a quart, so 7 cups is equal to
7 * (1/16) = 7/16 quarts.
Thus, the total amount of iced tea that was consumed during the party is 912 quarts -
7/16 quarts = 912 - 7/16
= 912 - 7 * (1/16)
= (912 * 16 - 7 * 1) / 16
= 1476 / 16
= 92.25 cups, rounded down to the nearest whole number, which is 92 cups.
It is important to note that the answer is given in cups and not quarts. Quarts is a unit of volume and cups is a unit of volume as well, but they are not equivalent. 1 quart is equal to 4 cups. If we wanted to express the amount of iced tea consumed in quarts, we would multiply the answer by 1/4.
In conclusion, the number of cups of iced tea consumed during the party is 92 cups, and if we express this in quarts it is equivalent to
92 * (1/4) = 23 quarts.

a gambler has a fair coin and a two-headed coin in his pocket. he selects one of the coins at random; when he flips it, it shows heads. what is the probability that it is the fair coin?
The probability of selecting the fair coin when a gambler has both a fair coin and a two-headed coin in his pocket is 50%.
This is because, when he selects one of the coins at random, it is equally likely that he has chosen either the fair coin or the two-headed coin. If he flips the coin and it shows heads, then the probability that it is the fair coin is still 50%, because either coin could have been selected and both would show heads.This is an example of a classical probability problem, which is based on the law of equal chances. This law states that when an event has multiple possible outcomes, each of those outcomes is equally likely to occur. In this case, there are two possible coins that could have been chosen, so each coin has a 50% chance of being selected. This means that the probability of selecting the fair coin is 50%.This also applies to events that have multiple outcomes which are not equally likely. For example, if a gambler has a fair coin, a two-headed coin, and a three-headed coin in his pocket, the probability of selecting the fair coin is still 50%. This is because the gambler has an equal chance of selecting any of the coins, regardless.
