Final answer:
The simplified expression of 1 + 4.25n + 3/2p - 3 + (-2p) +5/4n is -2 + 5.5n - 0.5p after combining like terms.
Explanation:
To simplify the algebraic expression 1 + 4.25n + 3/2p - 3 + (-2p) +5/4n, we need to combine like terms. The constants 1 and -3 can be combined, and the terms with 'n' and 'p' can each be combined respectively. Let's do this step by step:
Combine the constants: 1 - 3 = -2.Combine the 'n' terms: 4.25n + 5/4n = (17/4)n + (5/4)n = (22/4)n = 5.5n.Combine the 'p' terms: (3/2)p + (-2p) = (1.5 - 2)p = -0.5p.The simplified expression is -2 + 5.5n - 0.5p.

what two numbers multiplies to -90 and add to -8
Final answer:
The two numbers that multiply to -90 and add up to -8 are -10 and 2. This is found by factoring -90 and checking different factor pairs until the correct one is identified.
Explanation:
The student is asking for two numbers that when multiplied result in -90, and when added result in -8. This is a factorization problem that can be addressed by setting up a system of equations or by using intuition to guess and check pairs of factors. We are looking for a pair of numbers that have one positive and one negative number, because the product is negative (-90), and the sum is also negative (-8).
By listing out the factors of 90, we can test which pair of numbers, with one being negative, would multiply to -90 and add up to -8. After some trial and error, we find the pair that works are -10 and 9. -10 × 9 = -90 and -10 + 9 = -1. However, since the sum needs to be -8, then the correct pair is -10 and 2, because -10 × 2 = -20 and -10 + 2 = -8.

What is a conditional statement?A conditional statement is a type of logical statement that consists of two parts: a hypothesis (or antecedent) and a conclusion (or consequent).
The hypothesis is a statement that serves as a condition, while the conclusion is a statement that follows from the condition.
A conditional statement is usually written in the form "If p, then q", where p is the hypothesis and q is the conclusion.
The symbol "→" is often used to represent the phrase "if...then".
We have,
To make the inverse of a conditional statement "if p, then q", you simply negate both the hypothesis and the conclusion, and then switch their positions.
The inverse of "if p, then q" is "if not p, then not q".

At the end of a factory assembly line, completed widgets are deposited into a box until it is filled. if after 10 minutes the box contains 25 widgets and it takes 2 hours total to fill up a box, how many widgets must each box hold?
Final answer:
Each box must hold a total of 300 widgets.
Explanation:
To determine how many widgets must each box hold, we need to calculate the rate of production and then use it to find the total number of widgets produced in 2 hours (the total time it takes to fill the box).
First, we'll find out how many widgets are produced per minute. Since 25 widgets are deposited in 10 minutes, we divide the number of widgets by the time (in minutes) to get the rate:
Rate of production = 25 widgets / 10 minutes = 2.5 widgets per minute.
Now, we need to find out how many minutes are in 2 hours:
2 hours = 2 hours * 60 minutes/hour = 120 minutes.
Finally, we multiply the rate of production by the total production time (in minutes) to find out the total number of widgets per box:
Total widgets per box = 2.5 widgets/minute * 120 minutes = 300 widgets.

Find the equation (in slope-intercept form) of the line with the given slope that passes through the point with the given coordinates. slope: −2, ordered pair: (−5,1)
The equation of line is, y= -2x-9.
what is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
slope= -2
points= (-5, 1)
Now, using slope intercept form
y= mx+ b
1 = (-2)((-5) + b
1= 10 + b
b= -9
Thus, the equation of line
y= mx + b
y= -2x- 9
Hence, the equation of line is, y= -2x-9.

An artist wants to reduce the size of a drawing using a scale factor of 3:1 . The original drawing has an area of 720 square inches. What is area of the new drawing? Enter your answer in the box. in²
Answer: The area of the new drawing is 240 in².
Step-by-step explanation:
Hi, to answer this we have to use ratios:
Since the ratios is 3:1, it means that 3 units are equal to 1: 3/1
So, 720 units will be equal to x : 720/x
3/1 = 720/x
Solving for x:
x = 720/ (3/1)
x = 720/3
x = 240 in²
The area of the new drawing is 240 in².

△ABC has interior angles with measures x°, 100°, and 70°, and △DEF has interior angles with measures y°, 70°, and 20°. Using the given information, which statement is true? The triangles are similar because they each have an interior angle with a measure 70°. The two triangles are not similar because x≠y . The two triangles are not similar because y=90 so it is impossible to have three congruent angles. The two triangles are not similar because the interior angles are congruent but the side lengths are different.
△ABC has interior angles with measures x°, 100°, and 70°.
By using angle sum property, which states that the sum of measures of all three angles is 180 degrees.
[tex] x^{\circ}+100^{\circ}+70^{\circ}=180^{\circ} [/tex]
[tex] x^{\circ}=10^{\circ} [/tex]
Now, △DEF has interior angles with measures y°, 70°, and 20°.
By using angle sum property,
[tex] y^{\circ}+70^{\circ}+20^{\circ}=180^{\circ} [/tex]
[tex] y^{\circ}=90^{\circ} [/tex]
Now, we can say that,
"The two triangles are not similar because x≠y"
As one angle of measure 70 degree is common in both the triangles.
If 'x' would be equal to 'y' , then we could say that the triangles are similar by AA criteria.
Therefore, the two triangles are not similar because x is not equal to y.
A map of a public park shows a circular pond. there is a bridge along a diameter of the pond that is 0.85 mi long. you walk across the bridge, while your friend walks halfway around the pond to meet you at the other side of the bridge. how much farther does your friend walk? round your answer to the nearest hundredth. use 3.14 for π.
Answer:
Your friend walks about 0.48 miles farther than you.
Step-by-step explanation:
Find the circumference of the park.
C = πd Use the circumference formula.
C ≈ 3.14(0.85) Substitute for the diameter and π.
C ≈ 2.669 Multiply.
The circumference of the park is about 2.669 centimeters.
Find how far your friend walks when he or she walks halfway around the pond to meet you on the other side of the bridge. Divide the circumference by two.
0.785 ÷ 2 = 1.33
Your friend walks 1.33 miles.
Find how much farther your friend walks. Subtract the miles you walk from the miles your friend walks. Round your answer to the nearest hundredth.
1.33 − 0.85 ≈ 0.48

which sampling method would most likely be used in a poll of voters regarding a referendum calling for a national gun control standardization?
(A) Use satisfied random sampling
(B) Use simple random sampling
(c) Use convenience sampling
(D) Use cluster sampling
(E) Use systematic random sampling
Answer:
(A) Use stratified random sampling
Step-by-step explanation:
Since, the population include all the citizens of that country so it is quite large data and working on this population is quite time taken and costly. Thus, Sample must be taken and it must be taken by appropriate sampling method.
Here Stratified Sampling is used because by this sampling method peoples of every state, every cities, every village can be taken without much expense and in less time.
Further,
If the samples from the population are chosen randomly, where each and every unit has an equal chance of selection in a sample. This type of sampling is called Simple Random Sampling.
If the observers collect the sample as his\her convenience, then this type of sampling method is called Convenience Sampling.
In Cluster Sampling the population is distributed into a distinct group (clusters) and one or more groups (clusters) are chosen as a sample.
In Systematic Sampling the selection of sample is taken by some criteria . Like he\she is taken every 7th unit as a sample from the population.
Write a recursive definition for the set of odd positive integers.
Final answer:
A recursive definition for the set of odd positive integers starts with a base case of 1 and uses a recursive step where each subsequent odd integer is obtained by adding 2 to the current odd integer.
Explanation:
To write a recursive definition for the set of odd positive integers, you can define a base case and a recursive step. The base case is the smallest odd positive integer, which is 1. The recursive step will then generate the next odd integer by adding 2 to the current odd integer. Here's how you can express it:
Base case: Let O1 = 1, which establishes that 1 is the first odd positive integer.
Recursive step: For every odd positive integer On, there exists an On+1 = On + 2. This means that if you have an odd positive integer, the next one in the set can be found by adding 2 to the current one.
This definition ensures that every number generated by the recursive step will be odd since adding 2 to an odd number always results in another odd number, and starting from 1, guarantees that all numbers will be positive.
