PLEASE HELP!!!!!!!!!!!!!!! A small coffee cup holds 75% as much as a large coffee cup. If the small holds 36 units, how much does the large coffee cup hold?

Answers

Answer:

48 units

Step-by-step explanation:

Let x = the amount the large cup holds

36 = 75% of x

36 = .75x. (The word "of" indicates you will be multiplying)

36 ÷ .75 = x

48 = x

The number of cards in 4/5 of Hazel's baseball card collection is equal to twice the number in her brother's collection. If Hazel's brother has 80 cards, how many does Hazel's have?

Answers

Answer:

Hazel have 200 baseball cards in her collection.

Step-by-step explanation:

Let the number of card Hazel's have be x.

Given:

Hazel brother have = 80 cards

Also Given:

The number of cards in 4/5 of Hazel's baseball card collection is equal to twice the number in her brother's collection.

It means that 4/5 times of hazel card is equal to 2 multiplied with the number of cards hazel brother have.

Framing in equation form we get;

$(4)/(5)* x = 2* 80\n\n4 * x = 2 * 80 * 5\n\nx=(2* 80 * 5)/(4) =200$

Hence Hazel have 200 baseball cards in her collection.

(3xa+6):3+18=50 multumesc frumos

Answers

$(3a+6):3+18=50 \n\n (3a+6):3=50-18 \n\n (3a+6):3=32 \n\n 3a+6=32*3 \n\n 3a+6=96 \n\n 3a=96-6 \n\n 3a=90 \n\n a=90:3 \n\n \boxed{a=30}$

if 3xa=3 times a then
so the quantity (3xa+6) is divided by 3 so factor out the three and get3(a+2) divide by three and get (a+2)+18 and the associative propertyof addition allows us to move the parenthasees to (a+2+18)=50 or a+20=50 subtract 20 from both sides and get
a=30

or (3a+6)/3+18=50
3(a+2)/3+18=50
a+2+18=50
a+20=50
a=30

Planes A and B intersect in line s. If point V is a point on line s, then it lies on A. plane A only
B. plane B only
C. both plane A and B
D. neither plane A or B

Answers

Answer: C. Both plane A and B.

Step-by-step explanation: We very well know that if two planes intersect, then their intersection is a straight line.

We are given two planes- plane A and plane B, which intersect at a line S. Now, since 's' is the intersection of these two planes, so all the points on the line 's' will also be on the planes A and B.

It is given that 'V' is a point on the line 's', so 'V' will also lie on plane A as well as on plane B. Please see the attached figure.

Thus, the correct option is C. both plane A and B.

The answer would be C. both plane A and B because it's on line s which lies on both planes.
