Answer:
T is equal to I divided by pr. [tex]t=\frac{I}{pr}[/tex]
Step-by-step explanation:
This is the equation for interest.
I is interest.
P is the principal
r is the interest rate
t is the time in years
you have to isolate for t.
Because multiply p times r times t, divide both sides by pr due to the fact that division is the inverse operation of multiplication
Then you are left with t= i divided by pr.

Factor out the GCF.
o Use the difference of squares rule.
Use the perfect square trinomial rule.
Correct method to factor this expression are:
Factor by grouping.
Factor out the GCF.
What is factorization?A number or other mathematical object is factorised or factored in mathematics by expressing it as the product of numerous factors, often smaller or simpler things of the same sort. The four primary methods of factoring are the Grouping technique, the Difference in Two Squares, the Sum or Difference in Cubes, and the Greatest Common Factor (GCF). Numerous issues might be resolved by using the factoring of integers. Similar to this, factoring is an extremely effective method in algebra that is utilised at all levels. It offers a common approach to simplifying complex statements as well as, of course, solving quadratic equations.
The equation becomes:
= 4x² - 26x + 30
= 2 (2x² - 13x + 15)
= 2 (2x² - 10x - 3x + 15)
= 2 {2x (x - 5) - 3 (x - 5)}
= 2 (2x - 3) (x - 5)
Thus, the two methods are the best choices to factor this express are:
Factor by grouping.
Factor out the GCF.

HELP ASAP WILL GIVE 30 points. A toy box measures 4 ft by 3 ft by 2 ft. Explain whether increasing
the height by four times, from 2 ft to 8 ft, would increase the volume
by four times.
Answer:
yes, the volume would be increased by 4
Step-by-step explanation:
the volume for a box is l x w x h
lets say l = 4, w = 3, and h = 2
this would give us a volume of 24
now calculate the new volume: l x w x 4h
4 x 3 x (4 x 2) = 96 which is 4 times bigger than 24
Which equation can be solved
Answer: Choice B) 2x-60 = 180
===========================================================
Explanation:
A bit of the question got cut off. I'm assuming the full question reads "In this diagram, the measure of angle RQS is 60 degrees less than the measure of angle PQS"
The portion underlined is the part cut off where I'm making the assumption. If that assumption is correct, then we have
angle PQS = xangle RQS = x-60Those two adjacent angles form a straight line of 180 degrees
(anglePQS) + (angleRQS) = 180
(x) + (x-60) = 180
2x-60 = 180
which points to choice B as the answer.
Answer:
Step-by-step explanation:
∠RQS = x - 60°
∠RQS = 180° - x
x - 60° = 180° - x
2x - 60° = 180°

Use trigonometry to work out the size of angle x. Hypotenuse= 10cm, Adjacent= 9cm
9514 1404 393
Answer:
25.8°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the trig relations in a right triangle.
Cos = Adjacent/Hypotenuse
cos(x) = (9 cm)/(10 cm) = 0.9
Using the inverse cosine function, we can find the angle given its cosine.
x = arccos(0.9) ≈ 25.8°
Angle x is about 25.8°.

Answer:
Your correct answer is x = 42 .
My Step-by-step explanation:
Just turn the problem around by changing the subtraction to addition: 100 – x = 58 means the same thing as 100 – 58 = x, so x = 42.
x - 12 = -48 *
pls help quick
Answer:
x = -36
Step-by-step explanation:
Add 12 to both sides
x - 12 + 12 = x
(12 cancels out)
-48 + 12 = -36
x = -36

Answer to this equation 5x^2+2=7
Answer:
x=1
Step-by-step explanation:
Answer:
x= 1 and x= -1
Step-by-step explanation:
[tex]5x^{2} +2=7[/tex]
(subtract 2 from both sides)
[tex]5x^{2} =5[/tex]
(divide by 5 from both sides)
[tex]x^{2} =1[/tex]
(take the square root from both sides)
x=±√1
so,
x= 1
and
x= -1
