How to solve for x 15 + 8x = 45 + 6x
Answer:
15
Step-by-step explanation:
Let's solve your equation step-by-step.
15+8x=45+6x
Step 1: Simplify both sides of the equation.
8x+15=6x+45
Step 2: Subtract 6x from both sides.
8x+15−6x=6x+45−6x
2x+15=45
Step 3: Subtract 15 from both sides.
2x+15−15=45−15
2x=30
Step 4: Divide both sides by 2.

What is the approximate area of the congruent orange right triangles?
A. 17 in2
B. 31 in2
C. 33 in2
D. 51 in2
Answer: The answer is A 17in2
Step-by-step explanation:
In the question it states that the triangles are congruent (both the same).
first I found the area of the top orange triangle.
the formula to find the area of a triangle is [tex]\frac{1}{2} bh[/tex] (base times Height).
so I did [tex]\frac{1}{2} 3.23* 5.12[/tex] which gave me 8.27.
Since the triangles are congruent (the same) they would both have the same area along with base and height. so I multiplied 8.27 by 2 (because there are two triangles) and got 16.54 which rounds up to 17.
the question also stated to find the APPROXIMATE area (close to the actual, but not completely accurate or exact.)

Answer:
x=12
Step-by-step explanation:
90 = x + 42 + 3x
48 = x + 3x
48 = 4x
12 = x
Answer:
x = 12
Step-by-step explanation:
Since we are given a right angle, we can say that:
sum of all angles = 90 degrees
x + 42 + 3x = 90
4x = 48
x = 12
So, x is equal to 12 degrees!

15
12.5
Answer:
The answer would be 15.
Step-by-step explanation:
The first thing that you have to do is subtract 120 on both sides
40x + 120 = 720
-120 -120
40x = 600
Then you have to divide by 40.
40x= 600
600 ÷ 40 = 15
x = 15.

A circle has a radius of 6ft. What is the area of the sector formed by a central angle measuring 300 degrees
Answer:
30π ft^2 which is 94.25 ft^2 to the nearest hundredth.
Step-by-step explanation:
The area of the full circle is π * 6^2
= 36π so:
the area of the 300 degrees sector = 300 * 36 π / 360
= 30 π

Answer:
Correct option: second one -> n / (n+1)
Step-by-step explanation:
Writting the expression, we have:
[4n / (4n-4)] * [(n-1) / (n+1)]
First we can simplify the numerator of the first part, dividing numerator and denominator by 4:
[n / (n-1)] * [(n-1) / (n+1)]
The first fraction has n-1 in the denominator and the second fraction has n-1 in the numerator, so we can simplify then in the product:
n* [1 / (n+1)] = n / (n+1)
The final expression is n / (n+1), so the correct option is the second one.
The product of the expression, 4n/(4n - 4) × (n - 1)/(n + 1), is: n/(n + 1).
What is the Product of Polynomials?Product is the multiplication of two factors in the simplest form.
Thus:
4n/(4n - 4) × (n - 1)/(n + 1)
[4(n)/4(n - 1)] × [(n - 1)/(n + 1)]
Simplify
n/(n-1) × (n-1)/(n+1)
n/(n + 1)
Therefore, the product of the expression, 4n/(4n - 4) × (n - 1)/(n + 1), is: n/(n + 1).

PLEASE ANSWER. I will mark as brainliest for fist correct answer.
Step-by-step explanation:
If the total worth of the roll is 50 cents, we know that there are 50 pennies in the roll, and therefore the roll has a height of 50 * 1.52 = 76 mm. The radius of a penny is half its diameter, or 19.05 / 2 = 9.525.
We can find its volume with the formula (πr²) * h, where r and h are the radius and height respectively, and we can approximate 3.14 for π. Plugging these in, we have (3.14 * (9.525)²) * 76 ≈ 2160.8 mm³. Hope this helps!
Answer:
21,661.7 mm³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
Here, we're given the diameter as 19.05 mm, so the radius is ...
r = 19.05 mm / 2 = 9.525 mm
The thickness of one penny is 1.52 mm, but there are 50 of them in the roll. So the total height of this cylinder is ...
h = (1.52 mm)(50) = 76 mm
__
Using these numbers for radius and height in the volume formula, we find the volume of the roll of pennies to be ...
V = π(9.525 mm)²(76 mm) = 21,661.7 mm³
The approximate volume of the roll of pennies is 21,661.7 mm³.
