Answer 1
Answer:

Answer:

See explanation

Step-by-step explanation:

Points A(-3, -3), B(-2, 2), C(3, 3), and D(2, -2) are the vertices of a quadrilateral.

Find lengths of the sides as distances between points:

AB=√((-2-(-3))^2+(2-(-3))^2)=√(1^2+5^2)=√(26)\ units\n \nBC=√((3-(-2))^2+(3-2)^2)=√(5^2+1^2)=√(26)\ units\n \nCD=√((2-3)^2+(-2-3)^2)=√(1^2+5^2)=√(26)\ units\n \nAD=√((2-(-3))^2+(-2-(-3))^2)=√(5^2+1^2)=√(26)\ units

Since all lengths of sides are the same, quadrilateral ABCD is the rhombus.

Ginger sent 18 text messages yesterday Jerry sent 4 more than twice as many messages as Ginger sent. Kyle sent 15 fewer messages than Jerry. How many text messages did Jerry and Kyle send?

Answers

Applying algebra, we can conclude that: Jerry sent 40 messages, and Kyle sent 25 messages.

How to find the number of messages using algebra?

Let's use algebra to solve this problem.

Let's represent the number of messages Ginger sent as "G," the number of messages Jerry sent as "J," and the number of messages Kyle sent as "K."

We are given the following information:

Ginger sent 18 text messages, so G = 18.

Jerry sent 4 more than twice as many messages as Ginger sent, so J = 2G + 4.

Kyle sent 15 fewer messages than Jerry, so K = J - 15.

Now, let's substitute the value of G from the first equation into the second equation to find the value of J:

J = 2 * 18 + 4

J = 36 + 4

J = 40

Now that we know Jerry sent 40 messages, we can find Kyle's number of messages using the third equation:

K = 40 - 15

K = 25

So, Jerry sent 40 messages, and Kyle sent 25 messages.

So...
G sent 18
J sent 4+2(18)
K sent -15 of J

So...
18 times 2 is 36. Then add 4 to get 40. 
So, Jerry sent 40

then subtract 15 to 40... 40-15... which equals 25

Jerry is 40 texts
Kyle is 25 texts.
I hope this helps :)

A classroom globe has a diameter of 12 inches. What is the volume of the globe? Use 3.14 for pi. Round your answer to the nearest hundredth. 904.32 in3 

2144.66 in3

7238.23 in3

9202.77 in3

Answers

V=(4)/(3) \pi r^(3)

r=12/2=6
pi=3.14

V=(4)/(3)(3.14)*(6)^(3)

V=(4)/(3)(3.14)*216=904.32 in^(3)

The answer is 904.32 in^(3). Sorry. I used the wrong formula. ^^;
The answer would be 904.32

Felipe bought 3/4 of a pound of American cheese at the deli. She used 1/2 of the cheese to make sandwiches. How much cheese did she use?

Answers

She used 3/8 of the cheese. Since she used 1/2 of 3/4, you multiply 3/4 times 1/2. If you multiply straight across, the answer should be 3/8. If you need further explanation, just ask! Hope this helps! =D :D
The answer is 2/4 because 2 is half of 4.
