After the party, there was 0.5 of the pizza left. Angela ate 0.2 of the leftover pizza.

Angela said that she ate 0.01 of the whole pizza but Cal and Martha disagreed. Cal said it was 0.10 and Martha said it was 0.1

Mark all statements that are true.
True Not True

Angela is correct.

Cal is correct.

Martha is correct.

Nobody has the correct answer.

Answers

Answer 1
For one thing, Cal and Martha are technically in agreement; 0.1 and 0.10 are the exact same value. To see whether they're right, or whether Angela had it correct, let's take a look at the numbers 0.5 and 0.2.

As fractions, those two values would be [tex] \frac{5}{10} [/tex] and [tex]\frac{2}{10}[/tex], or [tex] \frac{1}{2} [/tex] and [tex] \frac{1}{5} [/tex] when reduced. When you cut the original pizza in half, you cut it into 2 equal slices. Cutting each of those two pieces into 5 equal pieces, we get a total of 5 x 2 = 10 equal slices. So, taking one of those slices at that point - as Angela did - would be taking [tex] \frac{1}{10} [/tex] - or 0.1 - of the whole pizza.

So, both Cal and Martha are correct.

Travis and Paula went to lunch. Travis ordered a sandwich for $7.50, and Paula ordered a burger for $5.25. after lunch they left a %15 percent tip for their waiter. how much money did the spend together?

Answers

First, you would need to determine how much they spent, not including tax.
$7.50 + $5.25 = $12.75

Next, you would need to create an equation for this problem.
($12.75 x 0.15) + $12.75

Now, all you would have to do is solve it.
($12.75 x 0.15) + $12.75 = $14.6625

They spent $14.6625 in total.

Answers

When you divide 972 by 10.8 you get the answer of 90. Hope this helps :)


If an apartment has  972 square feet of carpeting then from conversion we can say that it has 90 square meters.

What is conversion?

Conversion is basically converting one unit to another because there are different quantities expressed in different units. Like in one kilogram there are 1000 grams, etc.

How to convert units?

We have been given that an apartment has 972 square feet of carpeting and we are required to convert these 972 square units into square meters. We have been given that 1 square meter is equal to 10.8 square feet.

972 square feet=972/10.8

=90 square meters.

Hence if an apartment has  972 square feet of carpeting then from conversion we can say that it has 90 square meters.

What polynomial has roots of −6, 1, and 4?

Answers

The answer is c.

If you have a root (a), it can also be written as (x-a).

(x+6),(x-1),(x-4)

Multiply all of them together to get the equation

(x+6)(x-1)(x-4)=

(x2-x+6x-6)(x-4)=

(x2+5x-6)(x-4)=

(x3+5x2-6x-4x2-20x+24)=

x3+x2-26x+24

To find a polynomial with given roots −6, 1, and 4, we create factors (x + 6), (x - 1), and (x - 4). Multiplying these factors, we get the polynomial x3 - 5x2 - 21x + 24.

Finding the Polynomial with Given Roots

To find a polynomial with roots of −6, 1, and 4, we need to create factors that each set to zero at these roots. A polynomial is a product of its factors, and a root is a solution to the equation where the polynomial is equal to zero. The factors corresponding to the roots −6, 1, and 4 are (x + 6), (x - 1), and (x - 4) respectively. Multiplying these factors gives us the polynomial:

(x + 6)(x - 1)(x - 4) = x3 - (1 + 4)x2 + (4 - 1 - 24)x + (6 x 1 x 4)

Let's expand and simplify:

x3 - 5x2 - 21x + 24

Therefore, the polynomial with roots of
−6, 1, and 4 is x3 - 5x2 - 21x + 24.
