Answer:
x > -18
Step-by-step explanation:
If x was -18, -18/3 is -6 and -6-6 is -12. So, x must be greater than -18.
Answer:
x>-18
Step-by-step explanation:
Inequality answers are same as algebra but we use < or > for more than or less than and with line under for equal to.
x/3 -6 >-12
x/3 > -12 +6
x/3 > -6
x>-6 x 3
x> -18
Find the largest and smallest whole number when rounded to the nearest hundred to give 1600.
Answer:
Step-by-step explanation:
Smallest and largest whole number which gives 1600 when rounded to the nearest hundred.
The lowest whole number is 1550
The highest while number is 1649
Wheb rounding to the nearest hundred, the tens value which comes after the hundred value is carefully observed, of the tens value is less than 5, then it is rounded down to zero. However, if the tens value is greater than or equal to 5, it is rounded to 1 and added to the hundred value.
Numbers below 1550 will not round to 1600 (nearest 100) also numbers greater than 1649will not round to 1600(nearest 100).butvall numbers in between them will round to 1600 (nearest hundred)

Which numbers form a Pythagorean triple?
Answer:
A. 9, 12, 15
Step-by-step explanation:
9, 12, 15 is a set of numbers that form pythagorean triple because it satisfies the equation, a² + b² = c².
Where, c is the longest side while a and c are the two other legs of the triangle.
Thus:
9² + 12² = 15²
225 = 225 (this is true).

Diane had 0.9 grams of pepper. Then she used 0.6 grams of the pepper to make some scrambled eggs. How much pepper does Diane have left? 10min left!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
Diane had 0.3 grams of pepper left
Step-by-step explanation:
If she had 0.9 grams of pepper, we can subtract the amount of pepper she used (0.6) to find out how much she has left.
0.9 - 0.6 = 0.3
(sorry if this is confusing but I hope it helped)
Answer:
She has 0.3 grams of pepper left.
Step-by-step explanation:
0.9 g - 0.6 g = 0.3 g

What expressions represent 1/3 times the sum of 8 and 4
Answer:
1/3 * (8 + 4)
Step-by-step explanation:
Expression which represents 1/3 tines the sum of 8 and 4
Expressing mathematically,
Sum of 8 and 4 is written as (8 + 4)
1/3 of the sum is expressed as ; 1/3 x (8 + 4)
Hence,
1/3 * (8 + 4)
1/3 * 12
= 4
Expression is 1/3 * (8 + 4)
Result = 4
A merchant gains 20 %by selling an article for rs 480. what percent would he have gained or lost if he had sold it for rs 430
Answer: 7.5% gain
Step-by-step explanation:
First find the original price of the article.
Assume this price to be x.
x + (x * 20%) = 480
x + 0.2x = 480
1.2x = 480
x = 480/1.2
x = Rs. 400
Original price is Rs. 400.
If the merchant had sold the article for 430, the percent gain would have been:
= (Selling price - original price) / Original price
= (430 - 400) / 400
= 7.5%

Robero will randomly choose 1 book to read. What is the probability that he will
choose an adventure book?
Answer:
Step-by-step explanation:
How many books are there?
6+5+4+3 = 18 books total
How many are adventure books?
3
3 out of 18 books are adventure books
Robero has a 3/18 probability of choosing an adventure book.
Your teacher might want that probability in the lowest possible form. That is because it is the easiest to use and to understand.
You can do this by dividing both numbers by the "numerator" which is the first number in the fraction, (the adventure book count).
3/3 = 1
18/3 = 6
So the fraction can be reduced to 1/6.
Robero has a 1/6 chance of choosing an adventure book.
Find the median of the following numbers: 195, 230, 200, 226
Answer: 213
Step-by-step explanation: The median is the middle number
in the data set when the data set is written from least to greatest.
So let's start with writing ur data set from least to greatest.
So we have 195, 200, 226, 230.
Notice that there are two middle numbers.
If there are two middle numbers in the data set,
we find the median by taking their average.
In other words, we add the two middle numbers and divide by two.
So we have 200 + 226/2 or 426/2 which is 213.

The cycle time for trucks hauling concrete to a highway construction site is uniformly distributed over the interval 40 to 75 minutes. What is the probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes
Answer:
0.8333 = 83.33% probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
Uniformly distributed over the interval 40 to 75 minutes.
This means that [tex]a = 40, b = 75[/tex]
It is known that the cycle time exceeds 45 minutes
This means that we can use [tex]a = 45[/tex]
What is the probability that the cycle time exceeds 50 minutes?
[tex]P(X > 50) = \frac{75 - 50}{75 - 45} = 0.8333[/tex]
0.8333 = 83.33% probability that the cycle time exceeds 50 minutes if it is known that the cycle time exceeds 45 minutes
What are the solutions to –2x+ 2 = (3) +1?
Answer:
x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+2=3+1
Step 1: Simplify both sides of the equation.
2x+2=3+1
2x+2=(3+1)(Combine Like Terms)
2x+2=4
2x+2=4
Step 2: Subtract 2 from both sides.
2x+2−2=4−2
2x=2
Step 3: Divide both sides by 2.
2x2=22
x=1
A car travels 5/16 of a mile in 1/4 of a minute. How many miles will the car travel in 2 1/4 minutes?
Answer: 2 13/16 miles
Step-by-step explanation:
From the question, we are informed that a car travels 5/16 of a mile in 1/4 of a minute. The number of miles that the car will travel in 2 1/4 minute will be calculated as:
= 5/16 ÷ ( 1/4 / 2 1/4)
= 5/16 × 2 1/4 / 1/4
= 5/16 × (9/4 ÷ 1/4)
= 5/16 × 9
= 45/16
= 2 13/16 miles
The car will travel 2 13/16 miles in 2 1/4 minutes.
Using the coordinate plane below, find the distance between each pair of points. 1. (-3, 6) and (-3, 10) 2. (4, -5) and (-2, -5) 3. (6, 4) and (6, -1) 4. (-9, 1) and (-4, 1)
Answer:
1. 4
Step-by-step explanation:
(-3, 6) and (-3, 10)
|-3 - 3| = 0, |6 - 10| = 4
4² + 0² = 16, [tex]\sqrt{16}[/tex] = 4
(4, -5) and (-2, -5)
|4 - -2| = 6, |-5 - 5| = 0
6² + 0² = 36, √36 = 6
(6, 4) and (6, -1)
|6 - 6| = 0, |4 - -1| = 5
5² + 0² = 25, √25 = 5
(-9, 1) and (-4, 1)
|-9 - -4| = 5, |1 - 1| = 0
5² + 0² = 25, √25 = 5

9.) In a state with a sales tax of 7%, Hernando
spends a total of $73.98. What is the final price
after tax that Hernando has to pay? Show work.
Answer:
Final price = $79.16
Step-by-step explanation:
Given that:
Sales tax in the state = 7%
Amount spent by Hernando = $73.98
Amount of sales tax = 7% of 73.98
Amount of sales tax = [tex]\frac{7}{100}*73.98[/tex]
Amount of sales tax = 0.07 * 73.98
Amount of sales tax = $5.18
Final price = 73.98 + 5.18 = $79.16
Hence,
Final price = $79.16
