PLEASE ANSWER ASSAP!!! IF CORRECT WILL GIVE BRAINLY!!!!! Which one of these relationships is different than the other three? Explain how you know.
Answers
Answer:
The relationship B is different than the other three, because it has a different proportionality constant.
Step-by-step explanation:
All available options show direct relationships, which are defined as follows:
[tex]y\propto x[/tex]
[tex]y=k\cdot x[/tex] (1)
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]k[/tex] - Proportionality constant, dimensionless.
We proceed to use the following strategy based on the proportionality constant, that is:
[tex]k = \frac{y}{x}[/tex]
A different relationship must indicate a different proportionality constant:
Option A ([tex]x = 0.8[/tex], [tex]y = 4[/tex])
[tex]k = \frac{4}{0.8}[/tex]
[tex]k = 5[/tex]
Option B ([tex]x = 10[/tex], [tex]y = 55[/tex])
[tex]k = \frac{55}{10}[/tex]
[tex]k = 5.5[/tex]
Option C ([tex]x = 4[/tex], [tex]y = 20[/tex])
[tex]k = \frac{20}{4}[/tex]
[tex]k = 5[/tex]
Option D ([tex]x = 10[/tex], [tex]y = 50[/tex])
[tex]k = \frac{50}{10}[/tex]
[tex]k = 5[/tex]
The relationship B is different than the other three, because it has a different proportionality constant.

Elena knows that 5 servings of granola have 1,750 calories. if she eats 2 servings of granola,how many calories dose she eat
Answers
Answer:
700 calories
Step-by-step explanation:
1,750/5
=350
350colories per serving
So multiply 350 by 2
350x2
=700
Answer:
Elena eats 700 calories
Step-by-step explanation:
First, we need to find out how many calories are in one serving of granola. To do that, we will divide; 1750/5=350. We now know that there are 350 calories in one serving of granola. However, the problem is asking for how many calories are in two servings of granola. 350 x 2 = 700. Therefore, Elena eats 700 calories.

two fair dice are rolled. the score is the difference between the two dice. some of the possible scores are shown in the table.
c) which score has a probability of occurring 1/18
Answers
Answer:
Step-by-step explanation:
a). From the table attached,
Number in 1st column and 1st row = 1 - 1 = 0
Number in 1st column and 6th row = 6 - 1 = 5
Number in 2nd column and 4th row = 4 - 2 = 2
Number in 5th column and 2nd row = 5 - 2 = 3
Number in 6th column and 5th row = 6 - 5 = 1
b). Probability of scoring 1 = [tex]\frac{\text{Preferred outcome}}{\text{Total outcomes}}[/tex]
Preferred outcomes of getting = 10
Total outcomes = 36
Probability of scoring 1 = [tex]\frac{10}{36}[/tex]
= [tex]\frac{5}{18}[/tex]
c). Probability of occurring a score = [tex]\frac{1}{18}[/tex]
= [tex]\frac{1\times 2}{18\times 2}[/tex]
= [tex]\frac{2}{36}[/tex]
= [tex]\frac{\text{Preferred outcome}}{\text{Total outcomes}}[/tex]
Since, 5 is a number which has occurred twice
Score that has a probability of occurring of [tex]\frac{1}{18}[/tex] is 5.

Answer:
7000degrees/sec
Step-by-step explanation:
The question is not properly structured. Here is the correct question.
A pitcher's arm rotates at a speed of 7 degrees per millisecond (degrees/ms) . At what speed does the pitcher's arm rotate in degrees/s?
Before we proceed, you must know that we will be applying the following conversion;
1 milliseconds = 10⁻³secs
Given
Speed of pitcher's arm in degree per milliseconds = 7deg/ms
Required
We are to express in degree/sec
Using the conversion formula above;
[tex]7deg/ms = \dfrac{7^0}{1millisecs} \\\\converting \ to \ deg/s\\7deg/ms = \dfrac{7^0}{1millisecs} \times \dfrac{1}{10^{-3}s}\\7deg/ms = \dfrac{7^0}{10^{-3}s}\\[/tex]
[tex]7deg/ms = 7^0 \times 1/0.001s\\7deg/ms = 7^0 \times 1000/s\\7deg/ms = 7000^0/sec\\[/tex]
Hence the value in degree/sec is 7000degrees/sec
Suppose Jerome reads the following numbers of pages each day. Will he meet his goal of reading at least 85 pages by the end of the day Friday?
Answers
Answer:
Step-by-step explanation:
Jerome has already read 50 pages of a novel and read p pages each day from Monday to Friday.
If Jerome read at least 85 pages by the end of Friday, inequality will be,
50 + 5p ≥ 85
If Jerome reads 6 pages each day,
For p = 6,
Inequality will be,
50 + 5(6) ≥ 85
80 ≥ 85
It's not true.
Therefore, he will not meet his goal.
If p = 7,
Inequality will be,
50 + 5(7) ≥ 85
85 ≥ 85
It's true.
Therefore, he will meet his goal.
If p = 8,
Inequality will be,
50 + 5(8) ≥ 85
90 ≥ 85
It's true.
Therefore, he will meet his goal.

What type of bond is in NOF (Nitrosyl fluoride)?In a molecule of NOF, Oxygen is double bonded with Nitrogen. Nitrogen molecule of NOF is single bonded with flourine.
Rest of the valence electrons are not bonded.
Nitrogen's atomic number: 7, valence electron's count = 5Oxygen's atomic number: 8, valence electron's count = 6Florine's atomic number: 9, valence electron's count = 7Thus, with the above said description we will get:

What are some rules to solve an equation ?To solve an equation we follow BODMAS rule which stands for first solving which are inside brackets then we divide terms to each other if division is given.Then we multiply terms if multiplication is given.Next step we add terms if given.In last we do subtraction if it is in the given expression.If any of these operations are not given we just skip and do the next operation according to the BODMAS rule.
According to the given question
Charlotte wants to solve the equation 6(2x+1) – 3 = 4x – 5.
6( 2x + 1 ) - 3 = 4x - 5
12x + 6 - 3 = 4x - 5
12x + 3 = 4x - 5
12x - 4x = - 5 - 3
8x = - 8
x = -8/8
x = -1
