Answer:
8%
Step-by-step explanation:
If the block weighs 235 grams, we can do (253.8-235)/235=18.8/235=0.08. Because it's percent, we need to multiply by 100, so the answer is 8%.
Morgan missed 24 questions on her multiple choice math final that had a total of 200 problems. What percentage of questions did Morgan answer correctly?
Answer:
88%
Step-by-step explanation:
You start out by finding the number of questions she got correct
200 - 24 = 176 questions answered correctly
You then want to divide the number of question she answered correctly by the total number of questions there are.
176/200 or 176 ÷ 200 = 0.88
0.88 = 88/100 = 88%

The slope of the line is 3 and the intercept on the y-axis is 7.
Step-by-step explanation:
The slope-intercept form of the equation of a line is y=mx+c, where "m" is the slope of the line and "c" is the intercept of the line on the y-axis.
To find the slope and intercept of 6x+2y=14, you should solve for "y".
From the equation we get;
2y=-6x=14 or dividing each side by 2, we'll get y=3x+7.
Answer:
Domain: (−∞,∞), {x|x∈R}
Range: (−∞,∞), {y|y∈R}
Sylvia buys a case of water that contains 24 bottles and sells x number of bottles to her co-workers. Sam buys a case of water than contains 36 bottles and sells three times as many bottles as Sylvia sold to his co-workers. How many bottles of water did Sylvia sell if they ended up with the same number of bottles of water left over?
It is given that Sylvia sells x number of bottles and Sam sells three times as many bottles as Sylvia sold to his co-workers.
So, number of bottles Sam sold is 3x.
It is also given that, number of remaining bottle Sylvia and Sam have same.
So,
24 - x = 36 - 3x
3x - x = 36 - 24
2x = 12
x = 6
Therefore, Sylvia sells 6 bottles.
Hence, this is the required solution.

Part A: 50/100+3/100=x/100
Part B: Emma mistook 50/100 for 5/100 when she added it to 3/100. The correct sum would be 53/100
Answer:
Problem A:
5/10 + 3/100 = ?
Example:
Jake bought a cake. On Monday he ate 5/10 of the cake, he then put it in the fridge to store for later. On Wednesday Jake was looking through the fridge for a snack when he came across his leftover cake. His stomach was a bit small though so he only ate 3/100 of his cake. If Jake wants to finish the cake on Friday how much of the cake does he have to eat?
Problem B:
Emma added the value of 3/100 to 5/100 which is incorrect. The first graph is 5/10 or 1/2. The true value would be; 5/10 + 3/100 = 53/100. In conclusion, your answer would be 53/100 for problem B.

Sandro y Ezequiel son hermanos y el producto de sus edades es igual a

su edad y la de su padre es igual a 36. ¿Qué edad tiene Ezequiel?
Usando un sistema de ecuáciones, hay que Ezequiel tiene 11 años.
¿Qué es un sistema de ecuaciones?Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.
En este problema, las variables son:
x: La edad de Sandro.y: La edad de Ezequiel.z: La idad de su padre.Sandro y Ezequiel son hermanos y el producto de sus edades es igual a la edad de su padre, o sea:
xy = z
Sandro es 8 años menor que Ezequiel, o sea:
x = y - 8.
La suma de su edad y la de su padre es igual a 36, o sea:
x + z = 36.
z = 36 - x
z = 44 - y
En el primer ecuácion:
xy = z
(y - 8)y = 44 - y
y² - 7y - 44 = 0
(y - 11)(y + 4) = 0
y - 11 = 0 -> y = 11.
Ezequiel tiene 11 años.

Answer:
a₁ = 1
r = 3
Step-by-step explanation:

Step-by-step explanation:
4x15=60
60-30=30
2x15=30
Answer:
Option C is the correct answer.
Step-by-step explanation:
We have been given that a and b are parallel to each with a straight angle.
If a and a are parallel, then angle suspended by a and b will be equal to each other. It is because of Alternate angle of triangle.
Let's head to the question.
According to the above statement, we have the following equation.
2x°= 4x -30°
0r, 2x° - 4° = -30°
0r, -2x° = -30
0r, 2x° = 30°
0r, x = 30°/2°
0r, x = 15°
Hence, x = 15° will show that lines a and b are parallel.

What is sampling?It is when a group is taken from a population, and the data taken from the group can be taken to estimate the data for the entire population. A sample has to be representative of the population, that is, it has to avoid bias.
In this problem, the sample from Pack-and-Move was taken only from people who appeared in their commercials, meaning that the sample is biased, as these people are more likely to report high satisfaction, hence option D is correct.
