Group like terms:
= (4.9 x 7.9) x (10-6 x 10-5)
Multiply coefficients and add exponents:
= (38.71) x (10-11)
Convert to proper SN:

A cylinder has the net shown.
net of a cylinder with diameter of each circle labeled 2.6 inches and a rectangle with a height labeled 2 inches
What is the surface area of the cylinder in terms of π?
A) 8.58π in2
B) 6.89π in2
C) 18.72π in2
D) 10.40π in2
The correct answer is A) 8.58π in².
For us to find the surface area of the cylinder, we can consider the area of the two circular bases and the lateral surface area.
The formula for the surface area of a cylinder is:
Surface Area = 2πr² + 2πrh
Given that the diameter of each circle (base) is labeled as 2.6 inches, we can find the radius by dividing the diameter by 2:
Radius (r) = 2.6 inches / 2 = 1.3 inches
The height (h) of the rectangle is labeled as 2 inches.
Now we can calculate the surface area using the formula:
SA (Surface Area) = 2π(1.3)² + 2π(1.3)(2)
= 2π(1.69) + 2π(2.6)
= 3.38π + 5.2π
= 8.58π
Therefore, the surface area of the cylinder in terms of π is 8.58π square inches.

-Graphing Linear equalities with slope and y-intercept-
Answer:
I don't know how to type the table but the description is:
Slope= -3/2
y-intercept=0
y-intercept would be the b in y = mx + b and in this equation, it looks like there is no b but there is, it is just an invisible 0 because you don't need to add or subtract 0. The slope is -3/2 because m in the equation y=mx+b means slope.

HELPPP!!!!! Spencer has 16 blue marbles and 8 white ones. If he wants to place them in identical groups without any marbles left over, what is the greatest number of groups Spencer can make?
please give an explanation so i can stop asking for help
Answer: 8
Step-by-step explanation:
One way to find the GCF (Greatest Common Factor) is to list the factors of each number and find the largest factor that they have in common.The factors of 16 are: 1, 2, 4, 8, 16
The factors of 8 are: 1, 2, 4, 8
The largest factor that 16 and 8 have in common is 8.
This means that the marbles can be divided into 8 identical groups, each containing 2 blue marbles and 1 white marble.
Therefore, the greatest number of groups Spencer can make is 8.

Stacie sends 12 text messages per hour each day from 4 p.m. to 8 p.m. Which of the following equations can be used to calculate the number of text messages that Stacie sends during these hours in x weeks? A. y = 48x B. y = 420x C. y = 84x D. y = 336x
Answer: D
Step-by-step explanation:
Stacie sends text messages for 4 hours each day (from 4 p.m. to 8 p.m.), so she sends a total of 12 x 4 = 48 text messages per day.
To calculate the number of text messages that Stacie sends during these hours in x weeks, we need to multiply the number of days by the number of text messages per day.
Since there are 7 days in a week, Stacie sends 48 x 7 = 336 text messages per week.
Therefore, the equation that can be used to calculate the number of text messages that Stacie sends during these hours in x weeks is:
y = 336x
So the answer is D.
Answer:
The answer would be D: y=366x
Step-by-step explanation:
The question asks for an equation that says how many messages she sends in x amount of weeks.
First, you would need to find how many messages she sends in 1 week. She sends 12 messages in a 4-hour span (4 pm to 8 pm) so that makes 48 messages in that span a day. Then you multiply that by 7 to see how many she sends in a week.
y represents the total number of messages, this is unknown. X represents the number of weeks.
Hope this helps :)
50 POINTS NO INCORRECT OR FAKE ANSWER!
Answer:
1.3n + 9.6
Step-by-step explanation:
We can first gather the terms with the same variable to simplify the expression and combine like terms. In this case, we have 3.4n and -2.1n, which have the variable n. So, we can combine these terms by subtracting the coefficient of n:
3.4n - 2.1n = 1.3n
Next, we can add the constant terms 9.6:
1.3n + 9.6
So the simplified expression with combining like terms is 1.3n + 9.6. This means that the original expression 3.4n + 9.6 - 2.1n is equivalent to 1.3n + 9.6 after combining the terms with the same variable.
Answer: 9.6 + 1.3n
Step-by-step explanation:
3.4n + 9.6 - 2.1n
Combine like terms which are 3.4n and 2.1n
You do 3.4n - 2.1n = 1.3n
Now it's 9.6 + 1.3n
You would think to add 9.6 and 1.3n. No.
Leave it like that.
Answer: 9.6 + 1.3n

Cloey has to go to England for a interview with the King. A plane ticket costs $4,000. She has $10,000. She is also buying lessons to speak English. The lessons cost $4,000. How much cash does she have left over?
Cloey will spend a total of $4,000 + $4,000 = $8,000 on the plane ticket and the English lessons.
To calculate how much cash she has left over, we need to subtract the total cost from her initial savings:
$10,000 - $8,000 = $2,000
Therefore, Cloey will have $2,000 cash left over after buying the plane ticket and English lessons.

Two friends have gone on vacation together. On Monday, they each chose a different activity. One friend went in a helicopter and went 128 feet above the ocean. The other friend decided to go diving and he was 28 feet below sea level in the water. What is the distance between the 2 friends if they were directly above each other at the same time?
Answer: The answer would be 100.
Step-by-step explanation: The answer would be 100 because one friend is 128 feet above the ocean right, then the other friend is 28 feet below sea level in the water OK. So if one is 128 feet above sea level then that's a positive 128 feet. Now if the other friend is 28 feet below sea level in the water well then that's a negative 28 feet. So then what I would do is i would subtract 128 from 28 and get my answer of 100 feet apart from each other. Hope i helped and have an amazing day, and good luck on any upcoming test that you might have. I hope you Ace them all:) Good day buddy.

Answer:
Part A:110.8 ft
Part B:$76.526 or rounded to the nearest dollar is $77
Step-by-step explanation:
Part A: 6.2 x 4 = 24.8
24.8 x 2 = 49.6
4 x 3 = 12
12 x 2 = 24
6.2 x 3 = 18.6
18.6 x 2 = 37.2
49.6 + 24 + 37.2 = 110.8
110.8 ft sq
Part B: 6.2 x 4 = 24.8
24.8 x 2 = 49.6
4 x 3 = 12
12 x 2 = 24
6.2 x 3 = 18.6
49.6 + 24 + 18.6 = 92.2
92.2 x .83 = 76.526
$76.526 or rounded to the nearest doller $77
50 POINTS!!!!!! Please solve due tonight. Members of the band sold tickets for the fall concert. On monday they made 125$ in presales and sold 120 tickets at the door. For Tuesday they made 180$ in presales and sold 110 tickets at the door. if the band members earned the same amount of money each day what is the cost per ticket?
Answer:
$5.50
Step-by-step explanation:
Let x = price of 1 ticket at the door.
Monday income:
120x + 125
Tuesday income:
110x + 180
Set the two amounts of income equal and solve for x.
120x + 125 = 110x + 180
10x = 55
x = 5.5
