64 = x3
what value of x makes this equation true ?
Answer:
x = 4.
Step-by-step explanation:
64 = x^3
x^3 = 64
[tex]\sqrt[3]{x^3} = \sqrt[3]{64}[/tex]
[tex]\sqrt[3]{x^3} = \sqrt[3]{4 * 4 * 4}[/tex]
[tex]\sqrt[3]{x^3} = \sqrt[3]{4^3}[/tex]
x = 4.
Hope this helps!
Answer:
x = 3
The cube root of 64 is 4 because 4 x 4 x 4 = 64.
Cube roots have 3 identical factors, while square roots have 2 identical factors.
Hope this helps you!
A store sells paint sets. Each paint set costs the same amount. During a sale, the store reduces the price of each paint set by $1.30. Jasmine spends
$16.45 on 5 paint sets at the sale price.
What was the price of 1 paint set before the sale?
Answer:
$4.59
Step-by-step explanation:
At the sale price:
5 paints set cost Jasmine $16.45
Each paint set = Total cost of 5 paints set / 5
= $16.45 / 5
= $3.29
What was the price of 1 paint set before the sale?
Because the store reduces the price of each paint set by $1.30 before selling, we will add $1.30 to the price of each paint set during sales
Price of each paint set during sales = $3.29
price of 1 paint set before the sale = $3.29 + $1.30
= $4. 59
The cost of 1 paint set before the sale was $4.59
From the question, we are told that 5 paints set cost $16.45. From this, we can know the cost of 1 paint.
Cost of 1 paint set = cost of 5 paints set / 5
Cost of 1 paint set = $16.45 / 5
Cost of 1 paint set = $3.29
We are then asked the price of 1 paint set before the sale?
Since the store reduces the price of each paint set before selling it, this them means that we will add $1.30 to the price during the sales .
If the cost of 1 paint set during sales is $3.29, then
the cost of 1 paint set before the sale = $3.29 + $1.30
the cost of 1 paint set = $4. 59

Ezra counts the number of passengers who are already on the bus when he gets on each morning. His data for the last 15 days are shown below. What is the interquartile range of the data?
Answer:
6
Step-by-step explanation:
The data is
8,9,9,10,12,12,13,14,15,15,15,16,18,19,20
There are 15 data points
The median is the 15/2 = 7.5 rounding to 8

The mean score for a math test taken by Class A is 84, with the scores ranging from 78 to 94. The mean score for the same math test taken by Class B is 76, with the scores ranging from 68 to 88. Which BEST compares the scores of the two classes?
A) The highest score for the test was in Class B.
B) On average, the scores of Class A are lower than Class B.
C) On average, the scores of Class B are lower than Class A.
D) The scores of Class A vary more than the scores of Class B.
D) 22
Answer:
C
Step-by-step explanation:
mean score class A= 84
mean score class B= 76
the average/mean scores of class B< average/mean scores of class A
76<84
by process of elimination,
B is false- the mean scores class A are not lower than class B
A is false- the highest score is in class A with a score of 94 (highest score in class B=88)
D- not enough information is provided to determine coefficient of variation
Write four true conditional statements based on this biconditional statement.
An angle is a right angle if and only if it measures 90°.
Answer:
The four true statements are:
1. If an angle is a right angle, it measures 90°.
2. If an angle measures 90°, it is a right angle.
3. If an angle is not a right angle, it does not measure measure 90°.
4. If an angle does not measure 90°, it is not a right angle.
Step-by-step explanation:
Given the biconditional statement:
An angle is a right angle if and only if it measures 90°.
To find:
Four true conditional statements.
Solution:
First of all, let us the learn the concept of four true conditional statements from a given biconditional statement.
Let the biconditional statement be "[tex]a[/tex] is true if and only if [tex]b[/tex] is true.
Then the four true statements can be written as:
1. If [tex]a[/tex] is true then [tex]b[/tex] is true.
2. If [tex]b[/tex] is true then [tex]a[/tex] is true.
3. If [tex]a[/tex] is false then [tex]b[/tex] is false.
4. If [tex]b[/tex] is false then [tex]a[/tex] is false.
Here [tex]a[/tex] is "an angle is a right angle"
[tex]b[/tex] is "it measures 90°" .
So, the four true statements are:
1. If an angle is a right angle, it measures 90°.
2. If an angle measures 90°, it is a right angle.
3. If an angle is not a right angle, it does not measure measure 90°.
4. If an angle does not measure 90°, it is not a right angle.

-1 1/2 = -3/2
A rational number is a number that can be written as a fraction of integers.
-1 1/2 is the same as -3/2.
-3 and 2 are integers, so -3/2 is a fraction of integers.
Answer: yes
Answer: Yes
Step-by-step explanation:
-1 1/2 is a rational number because it is a non-repeating fraction and is still rational even if it is negative.

Question 3 (Not Answered). Om
Ned Question
Previous Question
Answer:
A. Plane B because it was 9.33 miles away
B. 48 units
Step-by-step explanation:
A. Since the airplanes fly at an angle to the runway, their direction forms a triangle with the runway with their height above the ground as the opposite of the angle and their distance from the airport as the hypotenuse.
So for airplane A with 44° angle of departure,
sin44° = y/h where y = height above the ground and h = distance from airport
So h = y/sin44° = 6/sin44° = 8.64 miles
So for airplane B with 40° angle of departure,
sin40° = y/H where y = height above the ground and H = distance from airport
So H = y/sin40° = 6/sin40° = 9.33 miles
Since airplane B is at 9.33 miles away from the airport whereas airplane A is 8.64 miles from the airport, airplane B is farther away.
B. We know that scale factor = new size/original size
Our scale factor = 4 and original size = 12 units. So,
new size = scale factor original size = 4 × 12 = 48 units.

Why does the inequality sign have to be flipped when multiplying and dividing by a negative number like in −2x > 10?
Answer:
When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.

Let's say she does the absolute minimum and buys 4 bags
Each bag has 7 servings, so there are 7*4 = 28 servings total.
I'm assuming each of the 30 guests gets one serving only. If so, then there wouldn't be enough food to go around (30-28 = 2 people are left out).
This means she cannot round x = 4.3 to x = 4. Instead, she must round up to get x = 5 as the lowest x value possible.
7x = 7*5 = 35 servings clears the hurdle.
So in short, x = 4 does not work in [tex]7x \ge 30[/tex] but x = 5 does work in

Answer:
A.
Step-by-step explanation:
This is a geometric sequence with common ratio -12/-3 = 4 ( -48/-12 = 4 and -192 / -48 = 4).
nth term = a1 r^(n - 1) so the 8th term
= -3 * (4)^(8 - 1)
= -49,152.
The 8th term of the geometric sequence is -768
