Answer:
(D same size and same shape)
Step-by-step explanation:
Congruent means the same size and shape.
Similar means the same shape, but not necessarily the same size
Answer:
The answer is : (D same size and same shape)
Step-by-step explanation:
Two shapes or figures are called congruent, when they are identical. When the angles are equal in degrees, they are called congruent angles and when sides are congruent, this means they have the same length.Two polygons are congruent if they have the same size and shape or if their corresponding sides and angles are equal.
Therefore, option D is correct.
which value makes this equation true -4x = 20
Answer:
x= -5 makes the given equation -4x = 20 true
Step-by-step explanation:
We have been given the equation;
-4x = 20
we are to determine the value of x that will make the equation true. We simply make x the subject of the formula;
divide both sides of the equation by -4;
(-4x)/(-4) = 20/(-4)
x = -5
Therefore, x= -5 makes the given equation -4x = 20 true
Answer:
[tex]x=-5[/tex]
Step-by-step explanation:
The given linear equation is:
-4x = 20
To find the value of x that makes the equation true, we need to solve for x.
We divide both sides by -4 to obtain:
[tex]\frac{-4x}{-4}=\frac{20}{-4}[/tex]
This is the sane as:
[tex]\frac{-4x}{-4}=\frac{-5\times-4}{-4}[/tex]
We cancel out the common factors to get:
[tex]x=-5[/tex]

line p contains point (6 ,- 5 and is perpendicular to line q the equation for line q is y=3x+5 write an equation for line q the find slope of line p write the recprocal of the slope you found in part 1
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
so
[tex]m1*m2=-1[/tex]
we have
[tex]y=3x+5[/tex] -----> equation of line q
the slope of line q is
[tex]m1=3[/tex]
Find the slope of line p
[tex]m1*m2=-1[/tex]
[tex]3*m2=-1[/tex]
[tex]m2=-1/3[/tex] ----> slope of line p
Find the equation of the line p
The equation into point slope form is equal to
[tex]y-y1=m(x-x1)[/tex]
we have
[tex]point(6,-5)[/tex]
[tex]m=-1/3[/tex]
substitute
[tex]y+5=-(1/3)(x-6)[/tex]
[tex]y=-(1/3)x+2-5[/tex]
[tex]y=-(1/3)x-3[/tex] ----> equation of the line p
see the attached figure to better understand the problem
The slope of line q is 3, so the slope of line p, which is perpendicular to line q, is -1/3. Substituting the given point (6, -5) and this calculated slope into the point-slope form of a linear equation, we find the equation of line p to be y = -1/3x + 3. The reciprocal of the slope -1/3 is -3.
Explanation:The equation of line q given is y=3x+5. The slope of this line is 3. Perpendicular lines have slopes that are negative reciprocals of each other. Therefore, the slope of line p, which is perpendicular to line q, should be the negative reciprocal of 3, which is -1/3. To find the equation of line p, use the point-slope form of a linear equation, which is y-y₁ = m(x-x₁), where m is the slope, and (x₁, y₁) is a point on the line. Substituting the given point (6, -5) and the calculated slope -1/3 into that formula, the equation for line p becomes: y - (-5) = -1/3 (x - 6), or simplifying further, y = -1/3x + 3. The reciprocal of the slope -1/3 is -3.

Answer:
Option B
Step-by-step explanation:
It is always wise to ask who or what the organization is asking. Always be safe.
Answer:
I would 100% go with
"Option B. Ask for the name of their organization and look for information about them to make sure they're authentic before he donates"
Step-by-step explanation:
That was the only logical decision, because for D. you can't just hope for the best and donate "blindfolded". A. was really not a smart decision because if you give someone your credit card number, they could easily take all the money they wanted off of it and put you in loads of debt. And then for C., it was the same with D., you can't just donate to an organization or charity fund when you have no idea if it's a probable cause or not. So, in conclusion "Option B." is your best and most logical answer.
What is the inverse equation of the function, y=5x-4
Answer:
y^-1 = (x + 4)/5
Step-by-step explanation:
To find the inverse equation of the function y=5x - 4, first we need to switch the x and y:
→ y = 5x - 4
→ x = 5y - 4
Now, solving for 'y':
→ x = 5y - 4
→ x + 4 = 5y
→ y = (x + 4)/5
therefore, the inverse equation is: y^-1 = (x + 4)/5

To find the total cost per mile to rent the car, add the rental cost for 5 days to the gasoline cost, then divide by the miles driven. Ruth Barr's total cost per mile was approximately $0.3785.
Explanation:
To calculate the total cost per mile to rent the car, we need to add the cost of renting the car for 5 days to the cost of gasoline and then divide the sum by the number of miles driven.
Calculate the rental cost for 5 days: 5 days × $59.95/day = $299.75.
Add the cost for gasoline: $299.75 (rental cost) + $137.76 (gasoline) = $437.51.
Divide the total cost by the number of miles driven: $437.51 ÷ 1156 miles = approximately $0.3785 per mile.
The total cost per mile Ruth Barr spent to rent the car was approximately $0.3785.
Quadratic equations and functions.
n^2+2n-15=0
Answer:
n = -5, 3.
Step-by-step explanation:
n^2 + 2n - 15 = 0
Let's check if we can factor this quadratic:
We need 2 numbers whose product is -15 and whose sum is +2.
There are 2 such numbers and they are +5 and -3, so the factors are:
(n + 5)(n - 3) = 0.
n + 5 = 0 or n - 3 = 0
therefore the zeroes are -5 and 3.
The number of books borrowed from a library each week follows a normal distribution. When a sample is taken for several weeks, the mean is found to be 190 and the standard deviation is 30.
There is a % chance that more than 250 books were borrowed in a week.
Answer:
There is a 2.275% chance that more than 250 books were borrowed in a week.
Step-by-step explanation:
Let the random variable X denote the number of books borrowed from the library each week. Then from the information given;
X is normally distributed with a mean of 190 and a standard deviation of 30.
We are required to determine the probability that more than 250 books were borrowed in a week;
This can be written symbolically as;
Pr(X > 250)
The first step is to determine the z-score associated with the value 250. This is obtained via standardizing X;
Pr(X > 250) = [tex]Pr(Z>\frac{250-190}{30})=Pr(Z>2)[/tex]
This is simply the area to the right of 2 in a standard normal curve. From the standard normal table, this area is; 0.02275
As a percentage this is equivalent to 2.275%
To find the probability of borrowing more than 250 books, calculate the Z-score and use a standard normal distribution table to find the corresponding percentile. Subtract this percentile from 1 to obtain the desired probability.
Explanation:The question involves using the properties of a normal distribution to find the probability that more than 250 books were borrowed in a week, given that the mean number of books borrowed is 190 and the standard deviation is 30. To determine this probability, one would calculate the Z-score for 250 books and then refer to a standard normal distribution table or use a calculator with normal distribution functions to find the area under the curve to the right of this Z-score.
To calculate the Z-score, we use the formula:
Z = (X - μ) / σWhere X is the value of interest (250 books), μ is the mean (190 books), and σ is the standard deviation (30 books).
Calculating it gives:
Z = (250 - 190) / 30Z = 60 / 30Z = 2The Z-score of 2 corresponds to a certain percentile in the standard normal distribution, which indicates the probability that a sample has a value less than 250. To find the probability of a value being more than 250, one would subtract this percentile from 1.

What type of number gets a mathematician in trouble the most when trying to use
function to model a real world situation? Why?
Answer:
Step-by-step explanation:
Interesting question. Perhaps an inverse relationship.
y = k/x where k is a constant like 10.
The problem begins to become a problem when x approaches 0 and that happens quite frequently.
I would say as a class of numbers, 0 is the most problematic. 0 was developed about 1100 years after the death of Christ so the concept is pretty subtle. The Romans had no value for 0 as a place holder. 2019 for them was not written with anything that resembled a zero. (MMXIX is how they would write it). That's got to be very awkward when giving parts of an inch in their engineering drawings.
The second group that probably causes some trouble would be the irrationals. pi for one. sqrt(3) for another. That took a while to develop as well.
Final answer:
The type of number that often gets mathematicians in trouble when using functions to model real-world situations is irrational numbers.
Explanation:
The type of number that often gets mathematicians in trouble when trying to use functions to model real-world situations is irrational numbers. Irrational numbers are numbers that cannot be expressed as a fraction or a ratio of two integers. They consist of an infinite decimal expansion without a repeating pattern. Examples of irrational numbers include π (pi) and √2 (the square root of 2).
Mathematicians may encounter irrational numbers when dealing with measurements, calculations, or any situation that requires precise numerical representations. Irrational numbers can cause difficulties because they cannot be represented exactly and must be approximated for practical use.
For example, if a mathematician is trying to model the distance a car travels in a given time, they may encounter irrational values when dealing with measurements involving π or √2. These values may need to be rounded or approximated to fit the model, introducing potential errors in the calculations.
Do 2 ratios form a proportion???
They form a proportion when both of the ratios are equivalent.
An example: 3/15 and 1/5 is a proportion because the are equivalent.
The reason why they are equivalent is because if you cross multiply meaning doing 3*5 which equals 15 and 15*1 which equals 15 so basically you multiply the numerator by the other fractions denominator and do the same for the other side and see if the numbers are the same if they are not the same they are not a proportion if they are the same they are a proportion.

Answer:
Final answer is [tex]t=5[/tex].
Step-by-step explanation:
Given equation is [tex]t^2-25=0[/tex].
Now we need to solve that equation for t when [tex]t>0[/tex].
[tex]t^2-25=0[/tex]
[tex]t^2-5^2=0[/tex]
[tex](t+5)(t-5)=0[/tex]
or [tex](t+5)=0[/tex], [tex](t-5)=0[/tex]
or [tex]t+5=0[/tex], [tex]t-5=0[/tex]
or [tex]t=-5[/tex], [tex]t=5[/tex]
Given that t>0
so that means t=-5 is not possible.
Hence final answer is [tex]t=5[/tex].

Sally's $8,800 savings is in two accounts. One account earns 2% annual interest and the other earns 6%. Her total interest for the year is $440. How much does she have in each account?
Answer:
In the 2% account, Sally has $2200 and in the 6% account, Sally has $6600.
Step-by-step explanation:
Suppose the amount invested at 2% is $X and the amount invested at 6% is $Y (assuming that the college student invested all his/her income on the two schemes). Therefore:
X + Y = 8800 (The sum of investments is basically the total income).
0.02X + 0.06Y = 440 (The sum of the interest received from the invested amounts is actually the total return).
Now solving these 2 simultaneous equations:
x + y = 8800 (Equation 1)
2x + 6y = 44000 (Equation 2)
From (Equation 1):
x = 8800 - y (Equation 3)
Put (Equation 3) in (Equation 2):
2(8800 - y) + 6y = 44000.
17600 - 2y + 6y = 44000.
4y = 26400
y = 6600.
To find x, substitute y = 6600 in equation 3. This gives:
x = 8800 - y.
x = 8800 - 6600.
x = 2200.
So in the 2% account, Sally has $2200 and in the 6% account, Sally has $6600!!!
