Answer:

Her answers wrong because the product of 7/8 times 1 1/2 equals 21/16.

Step-by-step explanation:

1 1/2=3/2

7/8*3/2=(7*3)/(8*2)

Determine if the two lines with the given slope are parallel, perpendicular, or neither. Circle your
Sati [7]

Answer:

As the lines are neither parallel nor perpendicular.

Therefore, the correct answer is ''neither''.

Hence, option C is correct.

Step-by-step explanation:

Given

m₁ = 3/2

m₂ = -3/2

We know that when two lines are parallel, they have equal slopes

But

m₁ ≠ m₂

3/2 ≠ -3/2

As the m₁ and m₂ are not equal.

Hence, the lines are not parallel.

We know that when two lines are perpendicular, the product of their slopes is -1.

Let us check the product of two slopes m₁ and m₂

m₁ × m₂ = 3/2 × -3/2

              = -9/4

              = -2.25

As

m₁ × m₂ ≠ -1

Thus, the lines are not perpendicular.

Conclusion:

As the lines are neither parallel nor perpendicular.

Therefore, the correct answer is ''neither''.

Hence, option C is correct.

What is 20% of 5 Please Help
Softa [21]
Hello there!

Start by asking yourself:"How to find the percentage of a number?"

We need to use the equation y = P% * x

In this case, the y is 20%

Y = P% * X

Y = 20% * X

Now we need to convert the percentage to decimal

P = 20%/100

P = 0.2

Then go back to the equation

Y= 0.2 * 5

Y = 1

The answer is 1

I hope the steps are easy to understand and hopefully the answer helps!

As always, I'm glad to help you today!

grigory [225]

Answer:

yuki has spent 22 percent , Rosetta spent 20 percent

step by step explanation:

1) if £100=100percent

then £22=x percent

x=(22×100)/100=22 percent

2) if £140=100 percent

then £28= x percent

x=(28×100)/140

x=2800/140

x=20 percent
