It cost $5.25 for a bottle of 150 vitamins. if the cost varies directly with the number of vitamins in the bottle, what should a bottle of 250 vitamins cost?
what is the equation o the situation?
Could you please give me the equation and show me how you got it please so I could understand... thanks.
Answer: $8.75 for 250 vitamins.
Step-by-step explanation:
To find how much each vitamin costs we can divide $5.25 by 150.
5.25/150 = 0.035. So each vitamin is equal to $0.035.
We can then multiply the cost of 1 vitamin by 250.
0.035 x 250 = 8.75 or $8.75.
We can also make an equation for this problem. Let the total cost be equal to y and each vitamin equal to x.
y = 0.035x
So the equation above states that the total cost, y, is the amount of vitamins that are bought.
What is the result of adding these two equations?
5x - y = 6
- 2x + y = 8
Answer:
x=14/3
Step-by-step explanation:
5x-y=6
+ -2x+y=8
----------------
5x+(-2x)-y+y=6+8
5x-2x-y+y=6+8
3x=14
x=14/3
I apologize if something is incorrect, please me know how to fix it. Thank you!

At a farmers market, a package of pears weighs 3lb and cost $9. Bananas are priced at 4lb per dollar. Use rates to explain witch kind of fruit is more expensive per pound
Answer:
The pears are more expensive per pound
Step-by-step explanation:
Find the cost per pound of the pears and bananas by dividing the cost by the number of pounds:
Pears:
9/3
= 3 ($3 per pound of pears)
Bananas:
1/4
= 0.25 ($0.25 per pound of bananas)
Since 3 is larger than 0.25, this means the pears are more expensive per pound.

Determinism each situation is likely to be normally distributed, normally distributed, skewed left, or skewed right.
a. The age at which people died in the U.S.
b. Selling prices of cars in 2019
c. The number of pets owned by students at your school.
d. The height of all adult females in Connecticut
(NOT A MULTIPLE CHOICE)
Answers
a) Skewed leftb) Skewed rightc) Normally distributed (symmetrical)d) Normally distributed (symmetrical)==============================================================
Explanations:
a) It's a very unfortunate part of life that everyone dies, and some do earlier than others. In general and on a grand scale of things, the older generations tend to die more frequently compared to the younger generations. In other words, an 90 year old man is more likely to die than say a 20 year old man. This is assuming that they both live in the same environment with other factors held constant as well. Because the older generation dies more frequently, this means we have the main cluster to the right (where the ages are older) and a long tail stretching to the left. The tail is the set of outliers of people who died at a fairly young age. Again, I'm not saying that young people don't die, but I'm saying that they don't die as much compared to older people. This tail on the left tells us we have negatively skewed data.b) Most cars are priced low so that people can afford them. So the main cluster is to the left while we have outliers to the right. The outliers to the right represent very expensive luxury cars. The outliers on the right side pull on the right tail to make it skewed to the right. We consider this positively skewed. In contrast, the one for part (a) was negatively skewed. Think of the positive and negative directions on the x axis to help figure out which direction things are being skewed in.c) Some people have a lot of pets, while others have few or none at all. In the middle is some average number where the highest peak is located. The distribution is fairly normal as with anything scattered about on average.d) Similar to part (c). There are some very short women, and some are very tall, but the majority are within some range of the average height. Doing a dot plot or a histogram of the distribution help leads to an approximately normal distribution, which is symmetric.Someone helllppppppppppoppppoop

Write an equation for the trend line shown. Type answer in y = mx + b format.
Answer:
y=1/4x+250
Step-by-step explanation:
Answer:
y = 12.5x + 250
Step-by-step explanation:
(4,300) , (8,350)
m = 350 - 300 / 8 - 4 = 25/2 = 12.5
y - 300 = 12.5(x - 4)
y - 300 = 12.5x - 50
y = 12.5x + 250

Step-by-step explanation:
Eric has $25 to purchase magazines and to pay for his lunch. Each
magazine costs $4 and his lunch costs $15. Which inequality can be used
to determine how many magazines, m, Eric can buy?
A. 4m - 15 > 25
B. 4m - 15 < 25
C. 4m + 15 > 25
D. 4m + 15 = 25
Answer:
B
Step-by-step explanation:
The maximum amount Eric can spend on magazines is $25 less the cost of lunch, $15.
The appropriate inequality sign would be less than since he cannot spend more than $25.
Also, the amount he can spend on magazines would be what is left after paying for lunch.
So the correct inequality is 4m - 15 < 25

Given:
HML = 180°
KMG = 180° (since both are lines)
∠KML = 83°
To find:
Measurement of ∠KMH
Steps:
Since we know HML is a line and equals to 180°, then
∠LMK + ∠KMH = ∠HML
83° + ∠KMH = 180°
∠KMH = 180° - 83°
∠KMH = 97°
Therefore the measurement of ∠KMH is 97°
