The area of Joe's square yard is 196 square meters. Since his house is on one side of the yard, Joe only needs to fence the other three sides of the yard. How many meters of fencing does Joe need to enclose his yard? (Number answer only, no units.)

Answers

Answer:

42

Step-by-step explanation:

So are is length times width,

since we are dealing with a square, then the length and the width are congruent

so we can say that, for this case:

a = length * length

hence

196 = length^2

14 = length

and

14 = width

since only 3 sides of this square are needed, one only has to multiply the length by 3

14 * 3

=42

so only 42 meters of fencing are needed

Joseph is making kebabs.he wants each kebab to have 3 pieces of meat and 4 pieces of vegetables.Which of the following could Joseph use to make kebabs without any leftovers?

Answers

Answer: Joseph could use C), D), and E) to make kebabs without any leftovers:

C) 30 pieces of meat and 40 pieces of vegetables

D) 45 pieces of meat and 60 pieces of vegetables

E) 72 pieces of meat and 96 pieces of vegetables

How were the answers determined? To solve for the answer, here are some pointers:

   Consider the given which states that each kebab has 3 pieces of meat and 4 pieces of vegetables, and Joseph wanted to make kebabs without any leftovers - meaning, there should be no extra piece of meat or no extra piece of vegetable.

   In choosing which is the answer, make sure that the number of pieces of meat must be divisible by 3 (pieces of meat), and the number of pieces of vegetables must be divisible by 4 (pieces of vegetables). This was also based on the given.

   Moreover, the quotient for meat and the quotient for vegetables must be equal to each other so that there will be no leftovers.

   Therefore, the answers are C), D), and E) because these three answers satisfy the conditions abo

A toy box contains eight green balls and four purple balls. Suppose you choose a ball at random and then replace it by putting it back in the toy box. You then choose a second ball. What is the probability that you have selected a green ball and then a purple ball?
Option A: 2/9
Option B: 1/2
Option C: 1/3
Option D: 2/3

Answers

Answer: C.  [tex]\dfrac{1}{3}[/tex]

Step-by-step explanation:

Given: Box contains 8 green balls and 4 purple balls.

Total balls = 8+4 = 12

event 1 = first picking green ball

event 2 = second picking purple balls.

As first ball was replaced, that means both events are independent.

Probability that you have selected a green ball and then a purple ball = P(purple ball )

Formula for probability = [tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]

Probability of selecting a purple ball (second pick)= [tex]\dfrac{4}{12}[/tex]

[tex]=\dfrac{1}{3}[/tex]

The required probability [tex]=\dfrac{1}{3}[/tex], so C is correct option.

If each unit on the coordinate plane represents one mile, what is the total distance the truck travels on its route?

Answers

Answer:

36.16 miles

Step-by-step explanation:

A recycling truck begins its weekly route at the recycling plant at point A, as pictured on the coordinate plane below. It travels from point A to point B, then points C, D, and E, respectively, before returning to the recycling plant at point A at the end of the day. The truck’s route is illustrated on the coordinate plane below. If each unit on the coordinate plane represents one mile, what is the total distance the truck travels on its route?

Answer:

The distance between two points X([tex]x_1,y_1[/tex]) and Y[tex](x_2,y_2)[/tex] is given as:

[tex]|XY|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

From the image attached, the coordinates of the plane are:

A(-1, -1), B(1, -1), C(5, 2), D(0,  13), E(-5, 2).

The lengths are:

[tex]|AB|=\sqrt{(1-(-1))^2+(-1-(-1))^2}=2\ units\\ \\|BC|=\sqrt{(5-1)^2+(2-(-1))^2}=5\ units\\\\|CD|=\sqrt{(0-5)^2+(13-2)^2}=12.08\ units\\\\|DE|=\sqrt{(-5-0)^2+(2-13)^2}=12.08\ units\\\\|AE|=\sqrt{(-5-(-1))^2+(2-(-1))^2}=5\ units[/tex]

But 1 mile = 1 unit

Total distance = |AB| + |BC| + |CD| + |DE| + |AE| = 2 + 5 + 12.08 + 12.08 + 5 = 36.16 miles

Which fraction is BIGGER?

Answers

From my understanding -4/5 is bigger.

Negative numbers closest to 0 are the greatest.

-7/10 < -4/5, so -4/5 is the bigger fraction.

Which inequality is equivalent to the given inequality? -4(x+7)< 3(x-2)

Answers

Answer:

x > -22/7

Step-by-step explanation:

To find out which inequality is is equivalent, you solve for x.

-4(x+7) < 3(x-2): distribute variables

-4x-28 < 3x-6: Add 6 to both sided

-4x-22 < 3x: add 4x to both sides

-22 < 7x: divide by 7

-22/7 < x: you can switch sides if prefered but you have to switch sign too

x > -22/7

The expression represents the second consecutive odd integer is X + 2

and for the third consecutive odd integer is X + 4.

What are integers?

All whole numbers and negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a set of integers is formed.

An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.

Given One example of consecutive odd integers would be 3, 5, 7, 9, ...

the difference between 2 consecutive numbers is

5 - 3 = 2

when X is the first odd integer,

the second consecutive odd integer is X + 2

difference between 3rd and first digit is

7 - 3 = 4

the third consecutive odd integer is X + 4

Hence adding the consecutive even numbers to the first digit of odd numbers gives the consecutive odd numbers.
