one teacher want to give each student 4/5 of a slice of pizza, if the teacher has 4 slices of pizza, then how many students will

GuDViN [60]

Answer:

The answer is 5 students.

Step-by-step explanation:

This problem is a division problem.

To solve, divide 4 by 4/5.

There is a strategy for this- Keep, Change, Flip.

Keep the dividend like it is, which is 4 or 4/1.

Change the division to multiplication.

And flip the divisor- 4/5 to 5/4.

When you multiply, you should get 20/4.

Simplify by dividing 20 by 4.

20 divided by 4 is 5.

So the answer is 5 students

Geometry question for my practice assignment

Tcecarenko [31]

5/3

Csc is equal to 1/sin

Sin= opposite/hypotenuse

So just take the inverse of what sine would be

Sin= 3/5

So Csc=5/3 :)

Jack and Julio each improved their yards by planting daylilies and geraniums. They bought their supplies from the same store.

o-na [289]

Cost of one daylily is $2 and cost of one geranium is $4.

Step-by-step explanation:

Let,

Cost of one daylily = x

Cost of one geranium = y

According to given statement;

x+5y=22 Eqn 1

13x+y=30 Eqn 2

From Eqn 1;

x=22 - 5y

Putting this value of x in Eqn 2;

$13(22-5y)+y=30\\286-65y+y=30\\-64y=30-286\\-64y=-256$

Dividing both sides by -64

$\frac{-64y}{-64}=\frac{-256}{-64}\\y=4$

Putting y=4 in Eqn 1

$x+5(4)=22\\x+20=22\\x=22-20\\x=2$

Cost of one daylily is $2 and cost of one geranium is $4.

O,60 is the same rotation as O, A. -300 B. 120 C. 300

aalyn [17]

The correct answer to the question that is being asked and presented above would be letter a. The problem 'O,60 is the same rotation as O,' should have the answer -300. Since both of them lie on the first quadrant when computed for the rotation.

Answer:

1. false

2. true

3. true

Step-by-step explanation:

1. Since a and b are right angles, a+b = 180, not 90, false

2. since a right angle is 90 degrees and b is a right angle, 90 + 90 = 180 true

3. B and A are right angles, so 180 - 90 = 90 true
