Jill drives 75 1/3 miles every hour.how many miles can Jill drive in 8 3/4 hours?

Answers

Answer 1
Answer:

Answer:

Distance travelled in  8 (3)/(4) hours is 659.17 miles .

Step-by-step explanation:

As given

Jill drives 75 (1)/(3) miles every hour .

i.e

Jill drives (226)/(3) miles every hour .

Now find out the distance travelled in 8 (3)/(4) hours .

Distance\ travelled = 8 (3)/(4)* miles\ travelled\ every\ hour

Distance\ travelled =(35)/(4)* (226)/(3)

Distance\ travelled =(7910)/(12)

Distance travelled = 659.17 miles (Approx)

Therefore distance travelled in  8 (3)/(4) hours is 659.17 miles .

Answer 2
Answer: 75(1)/(3)\ miles\ in\ 1\ hour\n\nx\ miles\ in\ 8(3)/(4)\ hours\n\nmaking\ cross\ multiplication\n75(1)/(3)*8(3)/(4)=x\n\nx=(226)/(3)*(35)/(4)=(7910)/(12)=659(1)/(6)miles\n\nJill\ can\ drive\ 659(1)/(6)miles

First, I'm not sure if this at all correct but um, I counted up all the pieces in both circles and there are 9 pieces in total. Since both circles have 1, 2, and 3 as the same numbers, there are 1 of each in the circles, so the probability is 2 over 9. Hope that helped and good luck! :]

X=pi*360/10*pi------> 36°

the answer is 36°

Which is the midpoint of AB if A is (-4,-1) and B is (10,5)?A. (-14, -6)

The midpoint of AB if A is (-4, -1) and B is (10, 5) is the point (3, 2). Hence, option c is the right choice.

What is the midpoint formula?

The midpoint formula of a line segment XY, where X is (x1, y1) and

Y is (x2, y2) is given by point M = ((x1+x2)/2, (y1+y2)/2).

How do we solve the given question?

We are asked to find the midpoint of AB, given A is (-4, -1) and B is (10, 5).

We use the midpoint formula to find it.

Taking A (-4, -1) as (x1, y1) and B (10, 5) as (x2, y2), we substitute the values in the formula: M = ((x1+x2)/2, (y1+y2)/2).

∴ M = ((-4 + 10)/2, (-1 + 5)/2)

or, M = (6/2, 4/2)

or, M = (3, 2)

∴ The midpoint of AB if A is (-4, -1) and B is (10, 5) is the point (3, 2). Hence, option c is the right choice.

Lets write this out:-

(3 × 3)3

First lets do what is in the parentheses, because we will follow PEMDAS. Then we will multiply, Lets do it:-

(3 × 3)3
(9)3
27

So, (3 × 3)3 = 27.

Hope I helped ya!! xD
3(3 × 3) First multiply inside the parenthesis;
3(9) Then multiply the last terms;
3 × 9 = 27
so your final answer is 27

Tthe options that can be used as a reason in a two-column proof are:

a. a premise

b. a definition

d. a postulate

In a two-column proof, each step or statement in the proof is accompanied by a reason to justify why that step is valid. The reasons are typically based on established mathematical principles, and the choices for reasons often include premises, definitions, postulates, and previously proven theorems. Let's delve into each of these options in more detail:

Premise (a): A premise is a statement or fact that is given to you as true. It serves as a foundational piece of information on which your proof is built. For example, if you're working with a geometry proof, you might be given the premise that two angles are congruent.

Definition (b): Definitions provide the meanings of mathematical terms and concepts. You can use definitions as reasons to clarify the meaning of specific terms or properties used in your proof. For instance, you might use the definition of a right angle to justify a particular statement in a proof.

Conjecture (c): Conjectures are unproven statements or hypotheses. They are not typically used as reasons in a proof because they lack the mathematical rigor and certainty required in a proof. However, conjectures can serve as a starting point for exploring and formulating proofs.

Postulate (d): Postulates (or axioms) are fundamental statements or principles in mathematics that are accepted as true without proof. Postulates are often used as reasons in geometric proofs to justify certain statements or relationships, such as the postulate that states two points determine a unique line.

Two column proofs are typically divided into two columns, statements and reasons, and each statement must be justified in the reasons column. Therefore, only postulates and definitions can be used in a two column proof reason
