Step-by-step explanation:
8x - 4 + 1.5x + 15
8x + 1.5x = 9.5x
-4 + 15 = 11
9.5x + 11
Expression = 9.5x + 11
Without Simplifying = 19/2x + 11
Answer:
9.5x + 11
Step-by-step explanation:
First, distribute the 4 to (2x - 1) to get 8x - 4. Distribute 3 to (1/2x + 5) to get 3/2x + 15. Put them back together to get 8x - 4 + 3/2x + 15. Combine like terms to get 9.5x + 11.

A flying object is moving at 150 m/s. It makes a complete and final stop in 12 seconds. Calculate the object’s acceleration.
Answer:
-12.5 m/s²
Step-by-step explanation:
v (final velocity) = 0
u (intial velocity) = 150 m/s
t = 12s
a= v-u/t
a = 0 - 150 / 12
a = -12.5 m/s²
A container of rain water is evaporating 1.2 centimeters a week. After 8 weeks what will be the change in rain water levels
Answer:
8.667
Step-by-step explanation:
After 8 weeks, the change in rainwater levels will be 9.6 centimeters.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
A container of rainwater is evaporating 1.2 centimeters a week.
After 8 weeks, the change in rainwater levels will be given as,
⇒ 1.2 x 8
⇒ 9.6 centimeters
After 8 weeks, the change in rainwater levels will be 9.6 centimeters.

How are mass and volume related on this graph?
As the mass decreases the volume increases
There is no relation
As the volume increases the mass decreases
As the mass increases, the volume also increases
The mass increases, the volume also increases.
What is proportionality?A graph is a line straight or curved that shows relation between two quantities out of which one varies as a result of change in other.
A graph is a line straight or curved that shows relation between two quantities out of which one varies as a result of change in other. To make it clear let us consider we have two variables x and y where, y=2x. The variable that is made to alter or change is called the independent variable.
As, from the graph we can see that the the volume represented by x axis and the mass represented by y axis show a direct relation.
As, the volume increases horizontally then the mass increases vertically.
let us take the coordinate (5, 25), (10, 50), (20, 100)
from the above coordinate we can see that the coordinate for both x and y axis increases.
Hence, mass increases, the volume also increases.

Which of the following is a step in multiplying 3/4 by 3/5? 2 А Adding 3 and 3 B. Finding the lowest common denominator of 4 and 5 C Multiplying 3 and 3 D Multiplying 3 and 5
=================================================
Explanation:
When you multiply fractions, you multiply the numerators together. So in this case we multiply 3 and 3 getting 9 as the updated numerator.
We also multiply the denominators together. The updated denominator is 4*5 = 20.
Overall, (3/4)*(3/5) = (3*3)/(4*5) = 9/20
The fraction 9/20 cannot be reduced because 9 and 20 do not have any common factors other than 1.
We don't have to worry about getting the LCD (lowest common denominator) since that is only applicable for adding and subtracting fractions.

Answer:
48
Step-by-step explanation:
Given the following question:
[tex]3(9)+3(7)[/tex]
To find the answer we need to remember when there is no operation between two numbers and the only thing that is separating them is a paratheses, we know to multiply the two numbers together.
[tex]3(9)+3(7)[/tex]
[tex]3\times9+3\times7[/tex]
[tex]3\times9=27[/tex]
[tex]3\times7=21[/tex]
[tex]27+21[/tex]
[tex]27+21=48[/tex]
[tex]=48[/tex]
Your answer is "48."
Hope this helps.
Answer:
48
Step-by-step explanation:
use PEMDAS
there is no Parenthesis
there is no exponets
there is multiplication
you can rewrite the question like this:
(3x9) + (3x7)
when you do the multiplication you will end up with 27+21. add them and you will get your answer of 48.
or
group the factors. since both of them have 3 in them you add the other quanities which is 9 and 7. you will now have 3(16). multiply it and you will get 48 as well

A. 0.105
B. 0.182
C. 0.386
D. 0.432
Answer: 0.432
Step-by-step explanation: I just took the test!
The probability that the student preferred morning classes given he or she is a freshman is 0.432. Option D. is the right choice.
What do we mean by the Probability of an event?The probability of an event is the fractional value showing how likely an event is to occur. It is determined by the formula,
The probability of an event
= number of outcomes favorable to the event/total number of outcomes
How do we solve the given question?We are asked about the probability that the student preferred morning classes given he or she is a freshman.
Total number of freshmen = 44 (in table)
Number of freshmen students who preferred morning classes = 19 (in table)
∴ The probability that the student preferred morning classes given he or she is a freshman = number of freshmen students who preferred morning classes/total number of freshmen = 19/44 ≈ 0.432
∴ The probability that the student preferred morning classes given he or she is a freshman is 0.432. Option D. is the right choice.

A rectangular prism is 15 inches long, 8 inches wide, and 6 inches high. What is the volume of a pyramid that has the same height as the prism.
Answer:
[tex]240 in^3[/tex]
Step-by-step explanation:
I'm assuming the pyramid base has to fit the prism, else the answer would be "as big as you want.
Now if you compare the formulas for the volume of a pyramid and a prism, you notice that the only difference is a factor of 1/3 (it will take 3 pyramids to fill a prism).
Volume of the prism is the product of the sides, ie [tex]15\cdot8\cdot6 = 720 in^3[/tex]. Volume of the pyramid will be 1/3rd of that, or [tex]240 in^3[/tex]
