find the sum of−2 5/10 and−5 4/15. then, in two or more complete sentences, explain the steps you used to add the mixed numbers.
Answer:
- 7 23/30
Step-by-step explanation:
-2 5/10 + -5 4/15
First simplify the fractions if possible
-2 1/2 + -5 4/15
Then, we need to get a common denominator
The common denominator in this case is 30
-2 1/2*15/15 + - 5 4/15*2/2
-2 15/30 + -5 8/30
Since the signs are alike we add
First the whole numbers
2+5 =7
Then the fractions
15/30+8/30 = 23/30
Add the fraction and the whole number together
7 23/30
Take the sign
- 7 23/30
If the fraction was improper, we would change it to a mixed number and add the whole numbers together
Final answer:
To find the sum of −2 5/10 and −5 4/15, convert them to improper fractions, find a common denominator, add them with the negative signs, and simplify if needed, resulting in −7 23/30.
Explanation:
To find the sum of −2 5/10 and −5 4/15, we first convert the mixed numbers into improper fractions. The first step is to add the whole numbers together, and then add the fractions separately.
Since both numbers are negative, when we add them, the answer will also have a negative sign, following the rule that when two negative numbers add, the answer has a negative sign. We find the common denominator for the fractions, which in this case is 30, and convert them accordingly. After adding the converted fractions, we simplify the result if possible.
To illustrate, for the whole numbers: −2 + (−5) = −7. For the fractions: −(5/10 × 3/3) + −(4/15 × 2/2) = −(15/30) + −(8/30) = −(23/30). Thus, the sum is −(7) − (23/30) or −7 23/30.

Hey there!
Solving for equation: y = 9x + 2
Replace (for now) 9x + 2 for y in the equation: y = 3x + 12
y = 3x + 12
↪ 9x + 2 = 3x + 12
ADD by -3 on both of your sides
9x + 2 + (-3x) = 3x + 12 + (-3x)
If you solved that correctly you should get: 6x + 2 = 12
ADD by -2 on both of your sides
6x + 2 + (-2) = 12 + (-2)
Cancel out: 2 + (-2) because it gives you 0
Keep: 12 + (-2) because it helps us solve for our x-interpret
12 + (-2) = 10
NEW EQUATION: 6x = 10
DIVIDE by 6 on your sides
6x/6 = 10/6
Cancel out: 6x/6 because it gives you 1
Keep: 10/6 because it helps us solve for our x-intercept
10/6 = 10÷2/6÷2 = 5/3
Thus our x = 5/3
Solving for y = 9x + 2
Replace x with 5/3 since we found our x
y = 9(5/3) + 2
9(5/3) = 15
15 + 2 = 17
Thus our y = 17
Overall answer: a = 5/3 & y = 17 ✅ (Option D)
Good luck on your assignment and enjoy your day!

Amy printed a square picture that was 225% the size of the original picture. The length of the side of her original picture was 4 inches. Choose True or False for each statement.
Answer:
because i cant see the true or false parts i can help by giving some basic answers
Step-by-step explanation:
the new length is 9 in. (4 x 2.25=9, change the percent to a decimal)because it is a square the area of the original is 16 in.^2 and the new area is 91 in.^2you change the percent to a decimalif there are more true or false parts to this question please leave a comment with them so i can hopefully answer them.
Final answer:
Amy's printed picture, which is 225% the size of the original picture with a 4-inch side, would have a new side length of 9 inches, making it larger than the original. The statements truthfully state that the picture is larger and the size scale is 2 ¹/₄ in terms of the sides, but the area would be scaled by the square of the side scale factor.
Explanation:
When Amy prints a square picture at 225% of the original size, and the original picture has a side length of 4 inches, then the new side length can be determined by calculating 4 inches × (225/100). The correct calculation for the side length of Amy's printed picture should be 4 inches × 2.25 (or 225%) which equals 9 inches.
Therefore, the statements should be evaluated as follows:
Amy's printed picture is larger than the original picture. - TrueThe length of the side of Amy's printed picture is 2 ¹/₄ inches. - False, since the correct side length is 9 inches.Amy's printed picture is 22.5 times the size of her original picture. - False, the size in terms of area scales with the square of the scale factor.Amy's printed picture is 2 ¹/₄ times the size of her original picture. - True, if considering the scale factor of the sides, but in terms of area, it would actually be (2.25)² times the original size.If g^2+1/g^2=51, find the positive value of g-1/g
Answer:
7
Step-by-step explanation:
Note that
(g - [tex]\frac{1}{g}[/tex] )² = g² - 2 + [tex]\frac{1}{g^2}[/tex] = 51 - 2 = 49
Take the square root of both sides
g - [tex]\frac{1}{g}[/tex] = [tex]\sqrt{49}[/tex] = 7 ← the positive value
Write a polynomial f(x) that satisfies the given conditions.
Polynomial of lowest degree with zeros of
(multiplicity 2) and
(multiplicity 1) and with f(0) = -1.
Can someone do this?
Answer:
[tex] f(x) = (x-4)(x-\frac{1}{2})^2 = x^3-5x^2+4.25x -1 [/tex]
Step-by-step explanation:
Recall, if we have a polynomial of the form [tex](x-a)^k \cdot (x-b)^m[/tex], then we say that a is a zero of multiplicity k and b is a zero of multiplicty m. For example, in the polynomial of the form [tex](x+5)^10(x-2)^3[/tex] -5 is a zero of multiplicity 10 and 2 is a zero of multiplicity 3. If we want to know the degree of the polynomial, just add the multiplicity of both zeros (13 in our example).
In this case, we know that the degree of our polynomial should be at least 3(multiplicity 2 and multiplicity 1). So, lets take the polynomial of the form
[tex]f(x)=(x-a)(x-b)^2)[/tex].
In here, a is a zero with multiplicity 1 and b is a zero with multiplicity 2. We are also given that
[tex] f(0) = -1 = (0-a)(0-b)^2 = -a\codt b^2[/tex].
Which implies that [tex] 1 = a\cdot b^2[/tex]. Since the square of any number is a positive number, it must happen that a>0. So, we have that
[tex]b= \pm \sqrt[]{\frac{1}{a}}[/tex].
We can choose any value of a and solve for b. Let us choose a=4. So we can have b=1/2 or b=-1/2. Let's use b=1/2. So our polynomial would be
[tex] f(x) = (x-4)(x-\frac{1}{2})^2 = x^3-5x^2+4.25x -1 [/tex]
which we can easily check that f(0)=-1.

r = 2 + 2 cos(theta)
Please select the best answer from the choices provided
A
B
C
D
Answer:
c. r = 3 + 2 cos(theta)
Step-by-step explanation:
At θ = 180°, the value of r is positive, but just a fraction of the value at θ = 0°. This eliminates choices 'b' and 'd'.
Choice 'a' would give r=3 and r=5 for those two cases, but the ratio of left extent to right extent looks smaller than 3/5. A graph of choice 'c' shows it matches the given figure.
Answer:
c. r = 3 + 2 cos(theta)

How many degrees are in a quarter circle?
o 25°
40°
o 90°
100°
Answer:
There are 90° in a quarter circle.
Answer:
90 degrees
Step-by-step explanation:
I believe its 90 degrees because if you have half of a protractor it only goes up to 180 degrees but if you have a whole one (dont know if it exists) you will have 360 degrees but if you put that into fourths it would result it in being 90 degrees.

Can more than one triangle be drawn with two side lengths of 6 inches and a nonincluded angle of 60°? Explain?
Answer:
No This is an unique triangle.
Step-by-step explanation:
Given that:
Two side lengths of 6 inches=> it is an isosceles triangle
According to the property of an isosceles triangle, the measurements of the two non-included angle are equal.
In this situation, a non included angle of 60°=> This is an equilateral triangle because the two non-included angles and include angle ( 180° - 2 *60°) are 60° .
This is an unique triangle.
Answer:No because you cannot form another triangle out of it. It only makes 1 shape.

most of the values are blank the mean ?
The mode is the value that appears most often in a data set. It is a measure of central tendency and is especially useful for describing categorical data or discrete sets. The correct answer is B. mode.
The mode, denoted as B in the options, is the value that occurs most frequently in a given data set. It is a statistical measure used to describe the central tendency of a dataset.
Unlike the mean, which calculates the average, and the median, which identifies the middle value, the mode focuses on the most recurring value. This is particularly helpful in analyzing categorical or discrete data. A dataset may have one mode (unimodal), more than one mode (multimodal), or no mode if all values occur with the same frequency.
Therefore, the mode is a valuable tool for understanding the distribution and characteristics of a dataset. (option B)
The complete question is:
The ____ is the value that appears most often in a data set.
A. mean
B. mode
C. median
D. range

Mary is creating valentine’s Day card for her friends and can choose from white,red,or pink construction paper to create a heart.On the heart she can use a black blue or green marker to write out her message and she can’t finish the valentine by sprinkling gold or silver glitter.Wh is the probability that her valentine to her friend will be on either red or pink construction paper with. black market and gold glitter?
Answer:
(1/9)
Step-by-step explanation:
Mary can choose from white,red,or pink construction paper to create a heart.
And she can use black, blue or green marker to write out her message and she can’t finish the valentine by sprinkling gold or silver glitter.
The probability that her valentine to her friend will be on either red or pink construction paper with black marker and gold glitter.
The probability that she uses red or pink construction paper = (2/3)
(since red or pink are two out of the total 3 sample spaces available for construction paper)
Probability that she uses black marker = (1/3)
(Black is one of the 3 sample spaces for markers)
Probability that she uses gold glitter = (1/2)
(Gold glitter is one of two sample spaces for glitters)
The required probability is then
(2/3) × (1/3) × (1/2) = (1/9)
