Deb wants to organize a group of friends to go to a karaoke studio Friday night. She must pay $30 to reserve a private karaoke room plus $5 for each person in the group. She also wants to have snacks for the group at a cost of $2 per person. How many people can Deb invite in order to spend a total of $65?
Fill in the blanks to create an equation to represent the situation.
blank x + 2x + blank = 65
Based on the solution below, the number of people Deb can invite in order to spend a total of $65 is 5 people.
How do we use an equation to find a number?Given:
blank x + 2x + blank = 65 ............................... (1)
Where:
x = Number of people Deb can invite
First blank with x variable = 5; since Deb must pay an additional $5 for each person in the group
Second blank without x variable = 30; since Deb $30 to reserve a private karaoke room
Substituting the relevant values into equation (1) and solving for x, we have:
5x + 2x + 30 = 65
7x = 65 - 30
7x = 35
x = 35 / 7
x = 5

The correct option is the first one, (1.176*10¹) is 14.7 times larger than (8*10⁻¹)
How many times larger is the first number than the second number?Here we want to see how many times larger is (1.176*10¹) larger than (8*10⁻¹), we can see that both numbers are in scientific notation.
To check that, we just need to take the quotient between the two numbers, we will get:
(1.176*10¹)/(8*10⁻¹) = (1.176/8)*(10¹/10⁻¹)
(1.176/8)*(10¹/10⁻¹) = (1.176/8)*(10¹⁻⁽⁻¹⁾) = (1.176/8)*10² = 0.147*10²
Now, returning to standard notation, we can rewrite:
0.147*10² = 14.7
The correct option is the first one, (1.176*10¹) is 14.7 times larger than (8*10⁻¹)

the true conditional "If 47% of the dogs

biconditional? Explain.
There is no way he can write a bi-conditional because there are only 2 g e n d e r s which are m a l e and f e-m a l e and as such he can't use if and only if due to the fact that all non - m a l e dogs are f e m a l e dogs and v i c e v e r s a.
What is a biconditional statement?A biconditional statement is a statement combing a conditional statement with its converse. So, one conditional is true if and only if the other is true as well.
Now, he wrote a true conditional which is "If 47% of the dogs

How can you rearrange two digits in the number 2,957,648 so that the value of the digit 4 is 10 times greater?
Answer:
2,957,468
Step-by-step explanation:
Each digit to the left is worth 10 times more than the same digit one place to the right.
If 2,957,648 becomes 2,957,468, the 4 moves from the tens place to the hundreds place, and now its value is 400 instead of 40, so it's 10 times greater.

How many distinguishable permutations can be formed from the letters in the word sassafras
In the word "SASSAFRAS", there 2520 permutations can be formed.
Permutation :A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
The order of arrangement in permutation is in linear form.
In the given word is “SASSAFRAS”. There are total 9 letters in which some letters appears several times, that is
S = 4 times.
A = 3 times.
F = 1 times.
R = 1 times.
We can the number of permutation to arrange this letter with the help of :
nPr = n! / (n - r)!
nPr = Permutation
n = Total number of objects
r = Number of objects selected
'!' = Factorial
Factorial :
Factorial (noted as “!”) is the product of all positive integers less than or equal to the number preceding the factorial sign. For example, 3! = 1 x 2 x 3 = 6.
So, nPr = 9!/(4!) (3!) (1!) (1!)
= (9×8×7×6×5×4×3×2×1)/(4×3×2×1)×(3×2×1)×(1)×(1)
= 3,62,880/ 24×6×1×1

use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet.
Use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet: TRUE
What are headlights?A headlamp is a lamp connected to the front of a vehicle to illuminate the road ahead. Headlamps are also commonly referred to as headlights, but in the most precise usage, the flashlight is the term for the device itself, and the headlight is the term for the beam of light produced and sold by the device. If you are driving with your high-beam lights on, you must dim them at least 500 feet from any oncoming vehicle to avoid blinding the oncoming driver. If you are within 200-300 feet of the vehicle you are following, you must use low-beam lights. When visibility is less than 500 feet and there is insufficient light/adverse weather, headlights must be turned on for 1/2 hour after sunset to 1/2 hour before sunrise.Therefore, the statement "use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet" is TRUE.

The second lawn that Makayla mows has a length of 70 feet.
If the first lawn Makayla mows is 10 feet long and 7 feet wide, use the formula for the area of rectangle to know the area of the first lawn.
A = l x w
Area of first lawn = 10 feet x 7 feet
Area of first lawn = 70 ft^2
If the area of the second lawn is 7 times as big as the first, then the area of the second lawn is:
Area of second lawn = 7 x Area of first lawn
Area of second lawn = 7 x 70 ft^2
Area of second lawn = 490 ft^2
If the second lawn has the same width as the first, which is 7 feet, using the formula for the area of a rectangle, solve for the length of the second lawn.
A = l x w
Area of second lawn = l x w
490 ft^2 = l x (7 feet)
