Answer:
HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome). Learning the basics about HIV can keep you healthy and prevent HIV transmission. You can also download materials to share or watch videos on basic information about HIV.
What is HIV?
HIV Overview
HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome).
There is currently no effective cure. Once people get HIV, they have it for life.
But with proper medical care, HIV can be controlled. People with HIV who get effective HIV treatment can live long, healthy lives and protect their partners.
Where did HIV come from?
History of HIV
HIV infection in humans came from a type of chimpanzee in Central Africa.
The chimpanzee version of the virus (called simian immunodeficiency virus, or SIV) was probably passed to humans when humans hunted these chimpanzees for meat and came in contact with their infected blood.
Studies show that HIV may have jumped from chimpanzees to humans as far back as the late 1800s.
Over decades, HIV slowly spread across Africa and later into other parts of the world. We know that the virus has existed in the United States since at least the mid to late 1970s.
To learn more about the history of HIV in the United States and CDC’s response to the epidemic, see CDC’s HIV and AIDS Timeline.

Mrs.; Jones bought 25 mangoes for $7.50. She sold 12 mangoes for 60 cents each and the remainder for 55 cents each. Calculate her percentage profit or loss. State whether she made a profit or loss
somebody help me plzzzzz
Answer:
She made a profit of $6.85
Step-by-step explanation:
she started out with 25 mangos for $7.50
she then sold 12 mangos for $7.15 leaving her with 13 mangos
she then sold the remaning mangos for 7.20
add $7.15 to $7.20 and you get $14.35
thats the gross profit, and you subtract that by $7.50, how much she bought the mangos for, to get her total net profit.

find the measure of the missing angles
b=
c=
Answer:
b=20
c=160
Step-by-step explanation:
b has the same measurement as the other angle that is across from it. c is 160 because the line that c is on is a straight line so it is 180 degrees, you subtract the other angle on the line,20, then you get the answer.
Answer:
b = 20° ( vertically opposite angles are equal)
b + c = 180°
=> 20 + c = 180
=> c = 180 – 20
=> c = 160°

A store buys 77 1/2 pounds of mulch in a large shipment. They divide the mulch up into bags that can each hold 2 1/4 pounds. The store sells one bag of mulch for $2.25. For each part of the question, show your work.
Solve the questions below.
A. how many full bags of mulch will the store make?
B. considering only the full bags, what is the total sales price of all the
bags of mulch?
Answer:
The store will make 24 bags
total sales will be $55
Step-by-step explanation:
finding the number of bagsade by the store,
compare, 2 1/4 pounds= 1 bag
77 1/2 pounds= ? bags
cross multiplication
number of bags the store will make will be 24 4/9 bags.
considering the full bags only which are 24 then the number of full bags the store will make are 24 bags.
total sales will be 1 bag= $2.25
24bags= ?
croas multiplication
the store will make $55
Leo and Vanessa both have a certain amount of money and plan to spend a certain amount each week until they run out. Vanessa starts with $400 and plans to spend $80 every 2 weeks. Leo plans to spend his money half as fast and has the same amount of money as Vanessa after 7 weeks.
Answer:
Leo started with $260
The balance of Vanessa and Leo after 7 weeks = $120
Step-by-step explanation:
Vanessa started $400
Vanesaa spending rate= $80/2weeks
In a week she would spend=$40/week
In 7 weeks should spend =40*7 = $280
Her balance after 7 weeks is =
$400 - $40 × x
$400 - $280
= $120
Leo spends at half of vanessa’s rate= $20/week
In 7 weeks leo will spend
$20 × x weeks
= 20 × 7 = $140
Since Leo and Vanessa’s balance would be the same after 7 days then leo balance is $120
Hence, the amount Leo started with $120 + $140= $260
In order to confirm your above answer
The Equation can be given as
$400 - $40 ×x = $260 - $20 × x
Where x = 7 weeks
$400 -40x = 260 - 20x
$400 - 40× 7 = $260 - 20× 7
$400 - 280 = $260 - 140
$120 = $120

Which answer choice shows the numbers in order from least to greatest?
A) 2/3, -1/2, 7/12, 0.82
B) -1/2, 1.3, 7,12, -0.45, 0.82
C) -0.45, -1/2, -2/3, 7/12, 0.83
D) -0.45, -1/2, 7/12, -2/3, 0.82
Answer:
c
Step-by-step explanation:
a has a positive before negative, so its ruled out
1.3 is more than -0.45, so b is ruled out
everything in c is in the right order. -1/2 is -0.5 and -2/3 is -0.66, 7/12 is -.58
d is incorrect because -2/3 isnt more than 7/12

• He donates 20% of his books to the national library
• He sells 1 of his books to a rare book dealer.
• The remaining books he sells online.

1. George works for a tech company. He has worked there for 5 years. He makes
$81,536 a year. He started with 8 days of paid vacation time. For each year he works at
the company he gains another three days of paid vacation to a max of 30 days.
a. How many paid vacation days does he now have?
Answer:
George now has 20 paid vacation days
Step-by-step explanation:
The given parameters are;
The number of years George has worked for the tech company = 5 years
The amount George makes annually while working for the company = $81,536
The starting amount of paid vacation time George has each year = 8 days
The annual increase in the amount of paid vacation time George has each year = 3 days
The maximum number of days of paid vacation allowable = 30 days
a. The number of paid vacation days George now has is given as follows;
The first year George had 8 days paid vacation
The next year George had 8 + 3 = 11 days paid vacation
The third year George had 11 + 3 = 14 days paid vacation
The fourth year George had 14 + 3 = 17 days paid vacation
The fifth year George had 17 + 3 = 20 days paid vacation
Therefore, George now has 20 paid vacation days.
