25. Explain the Error Jeremy factored 144x? – 100 as follows:
144x2 100 = (12x + 10)(12x – 10)
= 2(6x + 5)(6x – 5)
What was his error? Correct his work.
Given:
Consider the expression is
[tex]144x^2-100[/tex]
Jeremy factored the given expression and his steps are given.
To find:
The error in his solution.
Solution:
We have,
[tex]144x^2-100[/tex]
It can be written as
[tex]=12^2x^2-10^2[/tex]
[tex]=(12x)^2-10^2[/tex]
[tex]=(12x+10)(12x-10)[/tex] [tex][\because a^2-b^2=(a+b)(a-b)][/tex]
Taking out common factors from each parenthesis.
[tex]=2(6x+5)2(6x-5)[/tex]
[tex]=4(6x+5)(6x-5)[/tex]
So, Jeremy was incorrect because the common factor is [tex]2\times 2=4[/tex] instead of 2.
Therefore, Jeremy made his mistake in his last step.
The volume of a golf ball is approximately 4in.3 what is the diameter round you answer to the nearest whole number
A 4 in
B 6 in
C 1 in
D 2 in
Answer:
D. 2 inches.
Step-by-step explanation:
Given the following data;
Volume of golf (sphere) = 4 in³
A golf ball is spherical in shape. Thus, to find its volume we would use the formula for the volume of a sphere.
[tex] Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3} [/tex]
Substituting into the equation, we have;
[tex] 4 = \frac {4}{3} * 3.142* r^{3} [/tex]
Cross-multiplying, we have;
[tex] 12 = 4 * 3.142* r^{3} [/tex]
[tex] 12 = 12.568 * r^{3} [/tex]
[tex] r^{3} = \frac {12.568}{12} [/tex]
[tex] r^{3} = 1.0473 [/tex]
Taking the cube root of both sides, we have;
Radius, r = 1.016 inches.
To find the diameter;
Diameter = radius * 2
Diameter = 1.016 * 2
Diameter = 2.03 ≈ 2 inches.
Answer:
the answer is 2.

5/8^3+9-1/4^3= I really need help!!!
Answer: 3/8q^3 + 9
Step-by-step explanation:
1. combine like terms 5/8q^3 - 1/4q^3, need to make denominator the same to subtract so multiply 2/2 by 1/4q^3, 5/8q^3 - 2/8q^3 = 3/8q^3
2. final answer is : 3/8q^3 + 9

Step-by-step explanation:
It's in the middle of 0 and 1 (-1/2) on the x axis and for it to be in the middle of the two points the mid point stays on the x axis thus the y value (the value that goes up and down) is 0.
Share 48 in the ratio 3 : 5
Answer:
18 : 30
Step-by-step explanation:
3 + 5 = 8 (Total units)
48 ÷ 8 = 6
3 units = 6 x 3 = 18
5 units = 6 x 5 = 30
So it's 18 : 30

The length of lace would be the circumference of the circle.
Circumference = diameter x Pi
Circumference = 16pi cm
Circumference = 50.24 cm ( approximately)
Answer:
The circumference of the circle.

Please help! The expressions 3x - 9 and 23 - 5x represent the lengths (in feet) of two sides of an equilateral triangle. Find the length of a side. Show your work.
We are dealing with an equilateral triangle which has 3 equal sides.
length of a side = 3 ft
Since the three sides of an equilateral triangle are equal and we are given two sides to have lengths of 3x - 9 and 23 - 5x , it means that;
3x - 9 = 23 - 5x
Rearranging this gives;
3x + 5x = 23 + 9
8x = 32
x = 32/8
x = 4
putting 4 for x in 3x - 9, we have;
3(4) - 9 = 3 ft
Thus,
length of a side = 3 ft

I have two question I NEEDS HELP
1# Jason is participating in a walkathon. He writes the equation m = 2d + 50 to represent the amount of money he collects from each sponsor for walking d kilometers. What number represents the rate of change?
2# Cierra is keeping track of the amount of money in her lunch account each week. She writes the equation A = -6w + 40. What number represents the rate of change?
Answer:
The rate of change is the slope
In this case
m=2d+50 is a slope intercept equation.
where m is where the y would be
the 2 which is originally where the slope or (m) would be
the d for the (x)
and 50 for the y intercpet or (b)
so
#1=2
The expalantion is the same but different numbers, when asked for the rate of change look at the slope or the number next to the variable. Also put it in y=mx+b form to make sure the number is correct.
#2= -6

Answer:
A, commutative
Step-by-step explanation:
Commutative property means that you can switch around the numbers, and get the same answer. However, the commutative property is only compatible for addition and multiplication. I.e. 2+6 equals 6+2, but 2-6 does not equal 6-2.
