Gordon pours 4/9 quarts of milk from a pitcher equally into 4 mugs.a. Find the amount of milk in each mug.
b.Find the amount of milk in 3 mugs

Answers

Answer:

a) 1/9 quarts

b) 1/3 quarts

Step-by-step explanation:

Gordon pours 4/9 quarts of milk from a pitcher equally into 4 mugs.

a. Find the amount of milk in each mug.

To solve the first part of this question, we can simply use the idea of proportion;

Let x be the amount of milk in 1 mug

4/9 quarts = 4 mugs

x = 1 mugs

We will cross multiply

4x = 4/9

To get the value of x, we will divide both-side of the equation by 4

4x/ 4 = 4/9 ÷ 4

(on the left hand- side of the equation, 4 will divide 4 leaving us with x)

x = 4/9 ÷ 4

( This ÷4 can be change to become × 1/4)

x = 4/9 × 1/4

(The 4 at the numerator will cancel out the 4 at the denominator leaving us with 1/9)

x = 1/9

Therefore the amount of milk in each mug is 1/9 quart

b.Find the amount of milk in 3 mugs

For this second part of the question, we can also use proportion to solve;

Let x be the amount of milk in 3 mugs

4/9 quarts = 4 mugs

x = 3 mugs

Cross multiply

4x = 3 × 4/9

(At the right-hand side of this equation 3 can divide 9 which will give us 3 )

4x = 1 × 4 /3

4x = 4/3

We can now divide both-side of the equation by 4 to get the value of x

4x/4 = 4/3 ÷ 4

(On the left hand side of the equation, 4 will cancel out 4 leaving us with just x and on the right-hand side of the equation ÷ 4 can be changed to ×1/4)

x = 4/3 × 1/4

(4 will cancel 4 leaving us with 1/3)

x = 1/3

Therefore the amount of milk in 3 mugs is 1/3 quarts

a. each mug will be 1/9 because 4/9 divide by 4 is 1/9
b 3/9 or 1/3 because 1/9 times 3 is 3/9

A quadrilateral has 2 right angles. The measure of the third angle is 73 degrees. What is the measure of the fourth angle?

Answers

Angles in a quadrilateral add up to 360. So subtract the 3 angles you know. 360-90-90-73=107

quadrilateral add up to 360. So this how u going solve 360-90-90-73=107 and than ur answer is 107

1/6+(-2/3)= a.-4/6
b.1/2
c.-1/2
d.-5/6

plz only abitious and up

Answers

1/6+ (-2/3)
= 1/6 - 4/6
= -3/6
= -1/2

The correct answer is c. -1/2~

you can say -2/3 = -4/6 so : 1/6 - 4/6 = -3/6 = -1/2 and thats the simplest so the answer is c :))

Six copies of the sum of nine-fifths and three

Answers

i think copies is a multiplication and sum is to add together so
6x(9/5+3)
9/5 is 1 whole and 4/5. 1 whole plus 3 wholes is 4 Wholes so it is 4 wholes and 4/5 which is 24/5.
6x24/5 is (6x24 is 144) so its 144/5 so its 28 wholes and 4/5.
