80 newspapers in 5 piles equals newspapers in 1 pile

Answer:

To subtract two fractions, you need to have a common denominator. The common denominator for 8 and 3 is 24.

-5/8 = -15/24 (multiply both the numerator and denominator by 3)

-4/3 = -32/24 (multiply both the numerator and denominator by 8)

Now, we can subtract the two fractions by subtracting their numerators while keeping the common denominator.

-15/24 - (-32/24) = -15/24 + 32/24 = 17/24

Therefore, -5/8 - -4/3 = 17/24 in its simplest form.

Answer:

Luke has saved $21

Step-by-step explanation:

Answer:

According to the problem, Ramona has saved 3 times as much money as Luke, so:

Ramona's savings = 3x

Luke's savings = x

The problem tells us that Ramona has saved $63, so we can write an equation:

3x = 63

To solve for x, we can divide both sides by 3:

x = 21

Therefore, Luke has saved $21.

Yes, both triangles are similar.

Similar triangles are two triangles that have the same shape, but may differ in size. In other words, their corresponding angles are congruent and their corresponding sides are proportional. This means that if you were to scale one triangle up or down, it would still maintain the same shape as the other triangle.

In ΔABC,

AC² = 36² +15²

AC² = 1521 = 39²

AC = 39

In ΔXYZ,

XY² = 24² +10²

XY² = 676 = 26²

XY = 26

If the ratio of the sides of both triangles are similar So we can say that the both triangles are similar.

AB/XZ = BC/YZ = AC/XY

15/10 = 36/24 = 39/26

3/2 = 3/2 = 3/2

Here we can see that the ratio of the sides of both triangles are similar So we can say that the both triangles are similar.

In the above prompt involving a trajectory calculation, the correct option is: "The kick is not successful. The ball is approximately 5 feet too low." (Option A)

x component of trajectory =   73 cos 34   f/s  

   Now how long will it take to travel 49 yards (= 147 feet) ?

         147 / (73 cos 34) = 2.43 seconds

Initial y component of trajectory = 73 sin 34 f/s = 40.82 f/s  

    but this velocity is acted upon by gravity

       y = y0 + vot - 1/2 a t^2

The hiker's altitude after 4.5 hours is 448 feet.

What is arithmetic?

Arithmetic is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots.

Here, we have

Given: A hiker is climbing a local peak. After 1.5 hours of hiking, he is at an altitude of 220 feet. After 4 hours, he is at an altitude of 410 feet.

We have to find the hiker's altitude after 4.5 hours.

We have height as a function of time:

x = time, y = height

Our two points are (1.5, 220), (4, 410), and (4.5,x)

(4-1.5) = (410-220)

2.5 = 190

1 = 190/2.5

1 hours = 76 feet

0.5 hours = 38 feet

4.5 hours = 410 + 38 feet = 448 feet

Hence,  the hiker's altitude after 4.5 hours is 448 feet.

Answer:

the probability that a randomly chosen refill will fit correctly is 0.9780 (rounded to three decimal places).

Step-by-step explanation:

We can use the standard normal distribution to solve this problem. We first need to calculate the z-scores for the given diameters.

a) To find the probability that a randomly chosen refill will be too large, we need to find the probability of getting a diameter greater than 0.520 mm.

z-score = (0.520 - 0.5) / 0.007 = 2.857

Using a standard normal table or calculator, we find that the probability of getting a z-score of 2.857 or greater is 0.0021.

Therefore, the probability that a randomly chosen refill will be too large is 0.0021 (rounded to three decimal places).

b) To find the probability that a randomly chosen refill will be too small, we need to find the probability of getting a diameter less than 0.485 mm.

z-score = (0.485 - 0.5) / 0.007 = -2.143

Using a standard normal table or calculator, we find that the probability of getting a z-score of -2.143 or less is 0.0164.

Therefore, the probability that a randomly chosen refill will be too small is 0.0164 (rounded to three decimal places).

c) To find the probability that a randomly chosen refill will fit correctly, we need to find the probability of getting a diameter between 0.485 mm and 0.520 mm.

First, we find the z-scores for each diameter:

z-score for 0.485 mm = (0.485 - 0.5) / 0.007 = -2.143

z-score for 0.520 mm = (0.520 - 0.5) / 0.007 = 2.857

Using a standard normal table or calculator, we find that the probability of getting a z-score between -2.143 and 2.857 is 0.9780.

Therefore, the probability that a randomly chosen refill will fit correctly is 0.9780 (rounded to three decimal places).

Answer: the answer is C $912.

Step-by-step explanation: The interest on the loan is calculated as follows:

Interest = Principal x Rate x Time

where Principal is the amount borrowed, Rate is the interest rate as a decimal, and Time is the length of the loan in years. Substituting the given values, we get:

Interest = $800 x 0.14 x 1

Interest = $112

Therefore, the total amount to be repaid is the sum of the principal and the interest, which is:

Total amount = Principal + Interest

Total amount = $800 + $112

Total amount = $912

Let's use algebra to solve this problem.

Let x be one of the integers, and y be the other integer.

From the problem, we know that:

x = 4y + 17 (one integer is 17 more than 4 times the other)

xy = -15 (the product of the two integers is -15)

We can use substitution to solve for one of the variables. From the first equation, we can write:

y = (x - 17)/4

Substituting this expression for y into the second equation gives:

x(x - 17)/4 = -15

Multiplying both sides by 4 and expanding gives:

x^2 - 17x = -60

Rearranging gives:

x^2 - 17x + 60 = 0

This is a quadratic equation that can be factored as:

(x - 5)(x - 12) = 0

So the solutions are:

x = 5, y = (-12/4) = -3

x = 12, y = (-5/4) = -1.25

Since the problem states that the integers are both integers, the only valid solution is:

x = 5, y = -3

Therefore, the two integers are 5 and -3.

Answer:

The common difference in an arithmetic sequence is the constant difference between any two consecutive terms. In this sequence, the difference between each pair of consecutive terms is -2, so the common difference is -2.

The total resistance of three resistors in parallel s 2 Ohms. Option A

Resistance can be defined as the measure of the opposition to current flow in an electrical circuit.

Resistance is measured in Ohms, using the Greek symbol for omega (Ω).

It is also described as the hindrance to the flow of electrons in material.

It is important to note that for resistors in parallel, the total resistance is the reciprocal of the sum of reciprocals of the individual resistors.

This is represented as;

1/Rt = 1/R₁ + 1/R₂ + 1/R₃ ...

Where the variables , 'R' represented the resistors

Now, substitute the values, we have;

1/Rt = 1/4 + 1/8 + 1/8

The unitary method is a mathematical technique that involves finding a single unit value in order to solve a problem involving multiple units. In other words, the unitary method involves finding the value of one unit of a given quantity, and then using that value to calculate the value of another quantity that is related to it.

Here,

First, we need to convert pounds to ounces since the unit price is usually measured in terms of ounces. There are 16 ounces in one pound, so:

5 pounds = 5 x 16

= 80 ounces

The bag of potatoes costs $2.95 for 80 ounces, so the unit price per ounce can be found by dividing the total cost by the number of ounces:

The radian measure of an angle is directly proportional to the length of the arc intercepted by that angle on the unit circle.

Proportional is a mathematical concept that describes the relationship between two or more values that have a constant ratio. It is commonly used to describe the relationship between two or more variables, such as the size of an object in relation to another or the amount of a certain item in relation to the total amount. In proportionality, the ratio of the amounts remains consistent, no matter what the size of the values.

This means that as the angle increases, so does the length of the arc. This is because the length of an arc is determined by the angle measure of the central angle created by the arc, and the radian measure of an angle is the ratio of the arc length to the radius of the circle. Therefore, if the angle measure increases, so does the arc length.
