Multiply the monomials:
(3/4)pq, (1/2)qr^2, -5q^2r^3 and -6r^5
Given monomials are (3/4)pq , (1/2)qr² , -5p²r³ and -6r⁵
On multiplying them then
⇛ [(3/4)pq]×[(1/2)qr²]×[-5p²r³]×[-6r⁵]
⇛ [(3/4)×(1/2)×(-5)×(-6)]×(pq×qr²×p²r³×r⁵)
⇛[(3×1×-5×-6)/(4×2)](p×p²)×(q×q)×(r²×r³×r⁵)
⇛ (90/8)×p³×q²×r¹⁰
Since a^m × a^n = a^(m+n)
⇛ (45/2)×p³×q²×r¹⁰
⇛( 45/2 ) p³q²r¹⁰
Answer:- [(3/4)pq]×[(1/2)qr²]×[-5p²r³]×[-6r⁵] = (45/2)p³q²r¹⁰
The rainfall recorded in a certain city is given below. Calculate the average rainfall. 2.54 cm, 1.75 cm, 3.05 cm, 5.00 cm, 3.72 cm and 4.34 cm.
if you answer then i will mark you brainliest!!!
Answer:
3.4 cm
Step-by-step explanation:
average is the sum of all the values then divided by the number of values.
The average rainfall for the given values is 3.40 cm while The rainfall recorded in a certain city.
The average rainfall can be calculated by adding up all the recorded rainfall values and then dividing the sum by the number of values.
Let's calculate the average rainfall for the given values: 2.54 cm, 1.75 cm, 3.05 cm, 5.00 cm, 3.72 cm, and 4.34 cm.
Step 1: Add up all the values: 2.54 cm + 1.75 cm + 3.05 cm + 5.00 cm + 3.72 cm + 4.34 cm = 20.40 cm
Step 2: Divide the sum by the number of values (which is 6 in this case): 20.40 cm / 6 = 3.40 cm
Therefore, the average rainfall for the given values is 3.40 cm.

0.25(x + 4) - 3 = 28
Answer:
x = 120
Step-by-step explanation:
0.25(x + 4) - 3 = 28
Multiply 0.25 into the parenthesis
0.25x + 1 - 3 = 28
Combine like-terms
0.25x - 2 = 28
Add 2 to both sides
0.25x = 30
Divide both sides by 0.25
x = 120
22 of the 30 students in Evan's grade have a pet. What is the ratio of the number of students who do not have a pet to the number of students who have a pet?

What is the reference angle and cosine of StartFraction 7 pi Over 6 EndFraction ?
Answer:
[tex]\frac{\pi}{6}[/tex] radians
[tex]cos(\frac{7\pi}{6})=-\frac{\sqrt{3}}{2}[/tex]
Step-by-step explanation:
A reference angle is an acute angle between the terminal arm/terminal side and the x-axis. In this case, the reference angle is [tex]\frac{7\pi}{6}-\pi=\frac{\pi}{6}[/tex].
As for [tex]cos(\frac{7\pi}{6})[/tex], we can identify the value of it using the unit circle as attached below. Recall that points on the unit circle are defined as [tex](cos(\theta),sin(\theta))[/tex], so [tex]cos(\frac{7\pi}{6})=-\frac{\sqrt{3}}{2}[/tex].

George has $3 in his savings account. He then adds $4 per day to the account. Let y represent the total amount in the account after x days.
Which equation represents this situation in the form of y=mx+b ?
Question 9 options:
y = 4x + 3
y = 3x + 4
y = 3/4x - 3
y = 4/3x - 4
Answer:
The answer is the 1st option, y = 4x + 3
Step-by-step explanation:
x is the amount of days that the 4 dollars will be multiplied by
( 4 * x )
The + 3 is the money that George already had in his savings account, so that money will be added to the total amount in his savings account.
( 4x + 3 )
Lastly, the y stands for the total amount of money in his savings account so the answer is the 1st option.
y = 4x + 3

4x - 1 = 3(x + 1)
x=
Answer:
Step-by-step explanation:
4x - 1 = 3(x + 1)
4x - 1 = 3x + 3 [remove the parentheses by multiplying each term by 3]
4x = 3x + 4 [add 1 to both sides]
1x = 4 [Subtract 3x from both sides]
x = 4

Try it:
4x - 1 = 3(x + 1): ??
4*4 - 1 = 3(4 + 1) ??
