x is an integer.
The Lowest Common Multiple (LCM) of x and 12 is 120
The Highest Common Factor (HCF) of x and 12 is 4
Work out the value of x
Answers
Since 120 = 12 • 10 and LCM(x, 12) = 120, these suggest x is some multiple of 10.
HCF(x, 12) = 4 tells us that x is a multiple of 4.
If x is a both a multiple of 4 and 10, then the smallest x that fits both conditions is 4 • 10 = 40. (-40 also satisfies the criteria.)
The value of x for which the LCM and HCF of x and 12 are 120 and 4 respectively is 40.
What do we mean by Lowest Common Multiple (LCM) and Highest Common Factor (HCF)?
The Lowest Common Multiple (LCM) of the numbers is the smallest common multiple of the given numbers.
The Highest Common Factor (HCF) of the numbers is the greatest factor of the given numbers.
In the case of two numbers, the product of LCM and HCF is equal to the product of the numbers.
How do we solve the given question?We are given two numbers, x and 12.
Their LCM and HCF are 120 and 4 respectively.
We are asked to find the number x.
For two numbers, we know that the product of two numbers is equal to the product of their HCF and LCM.
∴ x*12 = 120*4
or, 12x = 480
or, x = 480/12
or, x = 40.
∴ The value of x for which the LCM and HCF of x and 12 are 120 and 4 respectively is 40.

Answer:
[tex]\huge\boxed{\sf x = 2.86}[/tex]
Step-by-step explanation:
Given proportionality:
x : 5 = 12 : 21
We know that:
Product of means = product of extremes
Means : 5,12
Extremes : x,21
5 × 12 = x × 21
60 = 21 x
Divide both sides by 21
60/21 = x
2.86 = x
x = 2.86

Answers
The total amount accrued, principal plus interest, with compound interest on a principal of $3,500.00 at a rate of 2.25% is $4,779.19.
Compound InterestGiven Data
Principal P= $3,500 Rate r = 2.25%Time t = 14 yearsFinal Amount A = ??A = P + I where
P (principal) = $3,500.00
I (interest) = $1,279.19
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 2.25/100
r = 0.0225 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 3,500.00(1 + 0.0225/1)^(1)(14)

Answers
Answer:
x = 85°
y = 45°
Step-by-step explanation:
For x, a line measures 180°, so subtract 95° from 180° to get 85°.
For y, all the angles in a triangle measure to 180°, and since we know x, add it to 50° and subtract it from 180°. 85° + 50° = 135°, and 180° - 135° = 45°
Answer:
x = 85
y = 45
Step-by-step explanation:
for x, angles on a straight line add up to 180 so 95 + x = 180 then evaluate for x
for y, angle in a triangle add up to 180 so 50+85 (as evaluated for x) +y= 180 and evaluate for y

If you borrow $700 for 5 years at
an annual interest rate of 7%, how
much will you pay altogether?
Answers
The amount you would pay altogether if you borrow $500 for 5 years at
an annual interest rate of 7% is $945.
How much would you pay altogether?The amount you would pay altogether is the sum of the amount borrowed and the interest.
Total value of the debt = interest + amount borrowed
Interest = $700 x 7% x 5 = $245
Total value of the debt = $245 + $700 = $945

Assume that 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A. What is the approximate probability that someone that gets an A actually studied for the Psychology test
Answers
The probability that someone that gets an A actually studied for the Psychology test is 0.15 or 15% if 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Let A = the students get an A
Let B = the student's studied for the psychology test
We know that probability:
P(B) = 60% = 0.60 and
P(A/B) = 25% = 0.25
We know that:
[tex]\rm P(A/B) = \frac{P(A\cap B)}{P(B)} = 0.25[/tex]
Now the probability that someone that gets an A actually studied for the Psychology test:
P(A∩B) = P(B) ×0.25
P(A∩B) = 0.60×0.25
P(A∩B) = 0.15
Thus, the probability that someone that gets an A actually studied for the Psychology test is 0.15 if 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A.

Given:
slope (m) = 4point (x₁, y₁) = (2, 0)Substituting the given values into the slope-point form of a linear equation:
[tex]\sf y-y_1=m(x-x_1)[/tex]
[tex]\implies \sf y-0=4(x-2)[/tex]
