please help math sucks
Answer:
Last option: {-5, -1, 2, 11}
Step-by-step explanation:
Required inequality is x > -6
That means every item in the set of values indicated should be > - 6
We should eliminate answers with - 6 since -6 is not greater than -6 it is ≥ -6
That leaves 2 and 4
When comparing negative numbers, a negative number which has absolute value greater than the absolute value of another number will always be less than the other number
For example, -11 has absolute value 11
- 6 has absolute value 6
11 > 6
So - 11 < -6
All the values in option 2 are therefore < - 6
Therefore last option is the correct one
-5 > -6, -1 > -6 and positive numbers are always greater than negative numbers

Find the value of x
Answer:
x = 18 !
Step-by-step explanation:
We can see that ∠CHD is equal to ∠GHF as they are vertically opposite angles. We can also see that the angles next to ∠CHD should all add up to 90° as it is a right angle!
This means that we have to add 32 and 32 then minus that from 90...
32 + 32 = 6490 - 64 = 26As the angle is the same we are now left with...
x + 8 = 26We just have to solve this by taking away 8 from both sides!
x + 8 - 8 = x26 - 8 = 18x = 18Hope this helps, have a lovely day! :)
Answer:
The answer is 18°, but please read the explanation so you can solve this problem in the future.
Step-by-step explanation:
To find the angle of x, we have to look at the angles in the first quadrant (in which the lines C and D are) first. To begin, a right angle is 90°. We see that there are two angles of 32° within the right angle (90°). Let's find the sum of 32 and 32.
32 + 32 = 64
Now, we can subtract 64° from 90° to find the angle of CD.
90 - 64 = 26
The angle between C and D is 26°.
If we look below at lines G and F, we can see that they are directly across from lines C and D, so they have the same angles. The arrow pointing to the angle of GF, which we know is 26°, says that x + 8° = 26°. To find x, let's subtract 8 from 26.
26 - 8 = 18
x = 18°

What is the value of m in the equation?
m+3/4=12?
_____-__
Answer:
To solve for the value of m in the equation:
m + 3/4 = 12
We need to isolate the variable m on one side of the equation. We can do this by subtracting 3/4 from both sides of the equation:
m + 3/4 - 3/4 = 12 - 3/4
Simplifying the left side of the equation by canceling out the 3/4 terms:
m = 12 - 3/4
To combine the two terms on the right side of the equation, we need to find a common denominator. Multiplying 12 by 4/4 gives us:
m = (48/4) - 3/4
Combining the terms on the right side of the equation:
m = 45/4
Therefore, the value of m in the equation is 45/4.
Answer:
m= 45/4

Rhiannon went to the store and bought two sweatshirts. She spent $72. What was the price of each sweatshirt?
Would you write an inequality or an equation?
To solve this problem, we can use the equation:
2x = 72
Where x represents the price of one sweatshirt. We multiply by 2 because Rhiannon bought two sweatshirts.
Simplifying the equation we get:
x = 36
Therefore, each sweatshirt costs $36.
We used an equation to solve this problem.

what is 12 divided by 3/4?
correct answer gets brainliest!
Step-by-step explanation:
To divide by a fraction, we can invert the fraction and multiply.
So, 12 divided by 3/4 can be written as:
12 * 4/3
Simplifying this expression, we get:
= 48/3
= 16
Therefore, 12 divided by 3/4 is equal to 16.
12 divided by 1/3 is 1
9 divided by 1/4 is 2.25
1/8 divided by 4 is 0.5
12 divided by 1/3 is 4

Ryan has a checking account balance of -$25. Write an absolute value statement to show how much money Ryan owes the bank.
Answer:
the absolute value of -$25 is [25]
Step-by-step explanation:
no matter if the number is negative or positive the absolute value will be what the number is or how many numbers away from 0 it is
Example: absolute value of 30 is [30] and absolute value of -50 is [50]
There is an equal amount of yellow, blue, green, and red marbles in a bag of 32 marbles. If Ed draws 4 marbles out of the bag with replacement, predict how many of the 4 marbles drawn should be blue.
1
4
8
32
Answer:
There are 32 marbles in the bag, and 1/4 of them are blue, so there are 32 * 1/4 = 8 blue marbles in the bag.
When Ed draws 4 marbles out of the bag with replacement, the probability of getting a blue marble on any given draw is 1/4.
The number of blue marbles Ed is expected to draw can be found by multiplying the probability of drawing a blue marble on each draw (1/4) by the number of draws (4):
Expected number of blue marbles = (1/4) * 4 = 1
Therefore, Ed is expected to draw 1 blue marble out of the 4 marbles drawn.
1) 1
Reasoning:
There are 4 different colors of marbles and 32 total marbles. 32/4 is 8, so there will be 8 of each at the start.
Because Ed picks 4 marbles, and there are 4 colors, we will divide 4 by 4 (4/4) and get 1.
If a perimetre of a rectangle is 38 cm and length is 12.5 cm What is the Area?
Answer:
81.25 cm^2
Step-by-step explanation:
perimeter = 2(l + w)
2(12.5 + w) = 38
12.5 + w = 38/2
w = 19 - 12.5
w = 6.5
Area = lw = 12.5 x 6.5 = 81.25
Answer:
81.25 cm²
Step-by-step explanation:
What is the area?The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.
To solve for the perimeter of a rectangle, the expression is:
(Let p = perimeter, l = length, w = width)
(l × 2) + (w × 2) = pTo solve for the width of a rectangle when given the perimeter, we can use this expression:
(p - [l × 2]) ÷ 2 = wInserting 38 in for 'p' and 12.5 for 'l':
(38 - [12.5 × 2]) ÷ 2 = 6.5To check our work, we can use the expression to solve for the perimeter:
(6.5 × 2) + (12.5 × 2) = 38Because the perimeter matches up with 38, we know the width of the rectangle is 6.5cm.
To solve for the area of a rectangle, we use this expression:
(Let a = area)
l × w = aInserting 12.5 in for 'l' and 6.5 in for 'w':
12.5 × 6.5 = 81.25Therefore, the area of the rectangle is 81.25 cm².

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Moussa sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
27 visitors purchased no costume.
112 visitors purchased exactly one costume.
3 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase one or more costumes as a percent to the nearest whole number.
Step-by-step explanation
The probability that the next person will purchase more than one costume is 0.03How to solve for the probabilityWe have the following details to solve the problem withThe people that did not purchase any costume = 103Those that purchased exactly one costume = 161Those that purchased more than one costume = 7The total number of persons that we have here would be 103 + 161 + 7= 271We are to find the probability that the next would purchase more than 1 costume.This is given as:7 / 271 = 0.0258To the nearest hundredth = 0.03Hence, 0.03 is the probability that the next person is going to buy more than one costume.
Answer:
115/142 or 80.99%
Step-by-step explanation:
total people who visited the website --> 27+112+3 = 142
total people who bought one or more costume(s) --> 112+3 = 115
So, 115/142 or 80.99%
Hope this helped
