Marty is spending money at the average rate of $3 per day. After 14 days he has $68 left.
a) Write the equation to model this situation, where x is the number of days.
b) Use the equation to determine how much money Marty had two weeks ago.
c) Use the equation to determine when Marty will run out of money if he continues to spend at this rate.
a) equation to model this situation can be
14x + 68 = 0
b) so, the money he had before two weeks are
14(3) + 68 = $120
c) equation to determine when Marty will run out of money if he continues to spend at this rate is 57 days and 8 hours.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Given:
Spent per day = $3
After 14 days = $68 left
a) equation to model this situation can be
14x + 68 = 0
b) so, the money he had before two weeks are
14(3) + 68 = $120
c) equation to determine when Marty will run out of money if he continues to spend at this rate.
let the total money be a
a - 14x = 120
a = 14(3) + 120
a = 172
So, if m is the number of days
172 - 3m = 0
3m= 172
m = 57 days and 8 hours

a chemist has 5 1/10 kg of calcium. if she uses 0.15 kg of the compound each time she performs an experiment, for how many experiments will her supply last?
The chemist can perform approximately 34 experiments with her 5.1 kg supply of calcium, given that she uses 0.15 kg of calcium for each experiment.
Explanation:The chemist has 5 1/10 kg of calcium and uses 0.15 kg of calcium for each experiment. To determine the number of experiments she can perform with her existing supply, we need to divide the total amount of calcium she has by the amount used in each experiment.
So, 5 1/10 kg = 5.1 kg. Dividing 5.1 kg by 0.15 kg, we get approximately 34. Therefore, she can perform 34 experiments with her current supply of calcium.

Flee, Fin, and Fliffers are 3 rabbits for sale in a pet store. Combined they represent 30% of the total number of rabbits for sale. What is the total number of rabbits for sale?
To find the total number of rabbits for sale in the pet store, set the total number of rabbits as 'x' and solve the equation 0.30x = 3 to get x = 10. Therefore, there are 10 rabbits for sale.
The question involves Flee, Fin, and Fliffers, three rabbits that constitute 30% of the total number of rabbits for sale in a pet store. To find out the total number of rabbits, let's designate the total number of rabbits as 'x'. Since the three rabbits are 30% of the total, we can write the equation
0.30x = 3
(because Flee, Fin, and Fliffers are three rabbits).
Solving for 'x', we divide both sides of the equation by 0.30 to get
x = 3 / 0.30.
Therefore, x = 10, which means there are a total of 10 rabbits for sale in the pet store.
Let's represent the total number of rabbits for sale as x. Since Flee, Fin, and Fliffers represent 30% of the total, their combined number is 0.30x. We can set up an equation: 0.30x=number of rabbits represented by Flee, Fin, and Fliffers. Solving for x, we divide both sides by 0.30x=number of rabbits represented by Flee, Fin, and Fliffers/0.30x. This implies that the total number of rabbits is 3.33 times the number represented by Flee, Fin, and Fliffers. So, if we know the number of rabbits represented by Flee, Fin, and Fliffers, we can multiply it by 3.33 to find the total number of rabbits for sale.
Complete answer;
Flee, Fin, and Fliffers are 3 rabbits for sale in a pet store. Combined they represent 30% of the total number of rabbits for sale. What is the total number of rabbits for sale?

Which of the following statements describes this sequence 1, 3, 9, 27
I this is an arithmetic sequence
II The common ratio for this sequence is 3
III the next term in the sequence is 54
IV The sequence can be described by the expression n+3
I and IV
I,II, and III
II
The given sequence is a geometric sequence with a common ratio of 3. The next term of the sequence is 81, not 54. The sequence cannot be described by the expression n+3 or as an arithmetic sequence.
Explanation:The sequence given is 1, 3, 9, 27, which is a sequence where each term is a multiple of the previous term. This type of sequence is called a geometric sequence. In this particular sequence, it is clear that every term is being multiplied by 3 to obtain the next term. Hence, the common ratio for this sequence is indeed 3 (Statement II).
This sequence is not an arithmetic sequence (Statement I is false) because the difference between successive terms is not constant. Furthermore, the sequence can't be described by the expression n+3 (Statement IV is false) because the sequence doesn't increment by adding 3 to each term; instead, it increments by multiplying the previous term by 3. Lastly, the next term in the sequence is not 54 (Statement III is false). It is 81 because you multiply the previous term (27) by the common ratio (3) to get 81.

Answer:
15 phones, option B.
Step-by-step explanation:
A cell phone company orders new phones = 500
The probability of a phone is being defective = 2.9%
2.9% of 500 phones are = [tex]\frac{2.9}{100}[/tex] × 500

Ernest thinks Ryan rested between 120 and 150 miles. Emma thinks he walked a flat part of the trail during that time. Who is correct and why? Which hypothesis matches the graph, Emma or Ernest’s? PLEASE HELP I GIVE BRAINLIEST
To determine who is correct, analyze the graph and compare it to the hypotheses of Ernest and Emma.
Explanation:Both Ernest and Emma have different hypotheses about Ryan's rest during the trail. Ernest thinks Ryan rested between 120 and 150 miles, while Emma believes he walked a flat part of the trail during that time. To determine who is correct, we need to analyze the graph to see if it matches either hypothesis.
If the graph shows a flat line between 120 and 150 miles, then Emma would be correct. However, if the graph shows a change in elevation during that distance, then Ernest's hypothesis would be correct. To identify the correct hypothesis, visually analyze the graph and compare it to the hypotheses put forth by Ernest and Emma.

(-2,1) and (3,-2)
Answer:
(–3, 6) and (6, –9) and (0, 2) and (5, 5)
Step-by-step explanation:
Given : Slope = [tex]\frac{-3}{5}[/tex].
To find: Which ordered pairs could be points on a line that is perpendicular to this line.
Solution : We have given that Slope = [tex]\frac{-3}{5}[/tex].
Slope = [tex]\frac{y_{2}-y_{1} }{x_{2}- x_{1}}[/tex].
For (–8, 8) and (2, 2)
Slope = [tex]\frac{2- 8 }{2 + 8}[/tex].
Slope = [tex]\frac{-6 }{10}[/tex].
Slope = [tex]\frac{-3 }{5}[/tex].
For (–5, –1) and (0, 2).
Slope = [tex]\frac{2+1 }{0 + 5}[/tex].
Slope = [tex]\frac{3 }{5}[/tex].
For, (–3, 6) and (6, –9)
Slope = [tex]\frac{-9- 6}{6 + 3}[/tex].
Slope = [tex]\frac{-15 }{9}[/tex].
Slope = [tex]\frac{-5}{3}[/tex].
For (–2, 1) and (3, –2)
Slope = [tex]\frac{-2 -1 }{3 +2}[/tex].
Slope = [tex]\frac{-3 }{5}[/tex].
For (0, 2) and (5, 5)
Slope = [tex]\frac{5 -2 }{5 -0}[/tex].
Slope = [tex]\frac{3 }{5}[/tex].
Therefore, (–3, 6) and (6, –9) and (0, 2) and (5, 5)

What is the equivalent fraction?
Drag the answer into the box to match the decimal.
0.7¯
The equivalent fraction of 0.7 is 7/9.
What is a fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
The decimal 0.7¯ (0.7777...) represents a repeating decimal in which the digit 7 repeats infinitely. To convert this to a fraction, we can use the following steps:
Let x = 0.7¯
Multiply both sides by 10 to move the decimal point one place to the right:
10x = 7.7¯
Subtract the left-hand sides of the first and second equations, and the right-hand sides of the first and second equations, to get:
10x - x = 7.7¯ - 0.7¯
Simplify both sides:
9x = 7
Divide both sides by 9:
x = 7/9
Therefore, the equivalent fraction for 0.7¯ is 7/9.
