See attached image.
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
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.

Elaine drives her car 70 miles and has an average of a certain speed. If the average speed had been 3mph more, she could have traveled 77 miles in the same length of time. What was her average speed
Answer:
30 miles/hr
Step-by-step explanation:
d / r = time distance divided by rate = time
70 / r = time and 77/(r+3 ) = time r = her original average speed
'time' is the same for both so we can equate the equations
70/r = 77/(r+3) cross multiply
70r + 210 = 77r
7r = 210
r = 30 m/hr

If you borrow $700 for 5 years at
an annual interest rate of 7%, how
much will you pay altogether?
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

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

In this question we must determine the volumes of pyramids of circular base and polygonal base (V). All the formulas needed are described below:
Volume of the pyramidV = (π/3) · B · h (1)
Base of the pyramid - CircleB = (π/4) · R² (2)
Base of the pyramid - Regular polygon
B = (n · L²)/(4 · tan 0.5α) (3)
Base of the pyramid - Right triangleB = (1/2) · b · z (4)
Base of the pyramid - RectangleB = b · z
Where:
R - Radiusn - Number of sides of the polygon.l - Side lengthα - Internal angle, in degree.h - Height of the pyramidb - Base of the right triangle/rectangle.z - Length of the right triangle/rectangle.Now we proceed to solve each pyramid:
1) Square, n = 4, α = 90°, L = 14 cm, h = 22 cm
B = 196 cm², V = 1437.333 cm³
2) Circle, R = 3 km, h = 8 km
B ≈ 28.274 km², V = 75,398 km³
3) Right triangle, b = 12 ft, z = 3.7 ft, h = 8 ft
B = 22.2 ft², V = 59.2 ft³
4) Rectangle, b = 23 yd, z = 9 yd, h = 5.7 yd
B = 207 yd², V = 393.3 yd³
5) Circle, R = 9.5 m, h = 12 m
B ≈ 283.529 m², V = 1134.116 m³
6) Regular pentagon, B = 110 mm², h = 11 mm
V = 403.333 mm³
7) Square,n = 4, α = 90°, L = 13 in, h = 7.2 in
B = 169 in², V = 405.6 in³
8) Regular triangle, n = 3, α = 120°, L = 16 ft, h = 24 ft
B ≈ 110.851 ft², V = 886.808 ft³

Answer:
y-intercept = -8
Step-by-step explanation:
Slope-intercept form of a linear equation: y = mx + b
(where m is the slope and b is the y-intercept)
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]

Discount 1: Take 5% off the original price of a care built last year and then receive a $3,500 rebate.
Discount 2: Take 10% off the original price of a car built this year and then receive a $1,250 rebate.
A customer is deciding between two cars.
Car R was built last year and has an original price of $25,340.
Car S was built this year and has an original price of $22,860.
Based on this information, which statement is true?
Question 10 options:
The customer would pay $24,073 for Car R.
The customer would pay $19,324 for Car S.
The customer would pay $23,107 for Car R.
The customer would pay $21,824 for Car S.
Answer:
3.55,11.25,48.20,49.413,42.184
Step-by-step explanation:
$3,500 + 0.05% = $3.55
$1,250 + 0.010% = $11.25
$25,340 + $22,860 = $ 48.20
$25,340 + $ 24,073 = $ 49.413
$22,860 + $ 19,324 = $42.184

The red arrow represents an outlier in the given dot plot. which the correct answer would be an option (A).
What is the dot plot?A dot plot, sometimes known as a dot chart, is a sort of basic histogram-like graphic used in statistics for very small data sets with discrete values.
An outlier is a value in a random sampling from a population that is significantly different from the other values. In some ways, this definition leaves it up to the analyst (or a consensus process) to determine what is abnormal. Normal observations must first be characterized before anomalous observations may be identified.
The dot plot is given in the question,
According to the given dot plot,
Most data are clustered around [12, 14], while 24 is distant from this interval.
Thus, the red arrow represents an outlier in the given dot plot.

Find the inverse of f(x)=5x-4.
The inverse of f is g(x)= ?
If g(x) is the inverse of f(x), then by definition of inverse function,
f(g(x)) = g(f(x)) = x
Given that f(x) = 5x - 4, we have
f(g(x)) = 5 g(x) - 4 = x
Solve for g(x) :
5 g(x) - 4 = x
5 g(x) = x + 4
g(x) = (x + 4)/5
