Which expression is equivalent to rm ÷ rn? (4 points)

1 answer:

6 0

I did not know what your question implied; so I answered it both ways.

rm ÷ rn

= $\frac{rm}{rn} = \frac{m}{n}$

$r^{m}$ ÷ $r^{n}$

= $\frac{ r^{m} }{ r^{n} } = r^{m - n}$

The difference between two numbers is 3. The sum of the same tow numbers is 13. What is the

Ber [7]

Answer: 40

Step-by-step explanation:

Let the two numbers be a and b.

Therefore,

a - b = 3 ....... i

a + b = 13 ....... ii

From equation I, a = 3 + b

Put a = 3+b into equation ii

a + b = 13

3 + b + b = 13

3 + 2b = 13

2b = 13 - 3

2b = 10

b = 10/2

b = 5

Since a = 3 + b

a = 3 + 5

a = 8

The product of the numbers will be:

= 8 × 5

= 40

The volume of the polyhedron is ______ yd3.

DochEvi [55]

Answer:

122,850 yd³

Step-by-step explanation:

The polyhedron is a right triangle prism

Area of the right triangle prism = ½*a*c*h

a = 91 yd

c = 60 yd

h = 45 yd

Volume = ½*91*60*45

= 122,850 yd³

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-5x + 6y = 55

4x + 3y = 34

Step 2: Rewrite Systems

4x + 3y = 34

Multiply everything by -2: -8x - 6y = -68

Step 3: Redefine Systems

-5x + 6y = 55

-8x - 6y = -68

Step 4: Solve for x

Elimination

Combine equations: -13x = -13
Divide -13 on both sides: x = 1

Step 5: Solve for y

Define equation: 4x + 3y = 34
Substitute in x: 4(1) + 3y = 34
Multiply: 4 + 3y = 34
Isolate y term: 3y = 30
Isolate y: y = 10
