10n+0.3=0.1n+0.3 Solve for N
Answer:
n=0
Step-by-step explanation:
Let's solve your equation step-by-step.
10n+0.3=0.1n+0.3
Step 1: Subtract 0.1n from both sides.
10n+0.3−0.1n=0.1n+0.3−0.1n
9.9n+0.3=0.3
Step 2: Subtract 0.3 from both sides.
9.9n+0.3−0.3=0.3−0.3
9.9n=0
Step 3: Divide both sides by 9.9.
9.9n/ 9.9 = 0/ 9.9
n=0
Answer:
n=0
Answer:
0
Step-by-step explanation:
10n - .1n = 9.9n
9.9n + .3 = .3
subtract .3 from the other one and get 0
9.9n = 0 then divide and it comes out to 0

Distance between points (2, 1) and (8,9) is 10.
Step-by-step explanation:
let me know if you need an explanation :)
hope this helps and is right. p.s i really need brainliest :)
Answer:
10
Step-by-step explanation:
distance formula is the square root of x sub 1 - x sub 2 quantity squared +y sub 1 + y sub 2 quantity squared. In this case it would look like the square root of (8-2)^2 +(9-1)^2. this would simplify to the square root of 100, which is 10.

A rectangle has a length that is 3 more than the width. If the area of the rectangle is 28 units squared, what are the dimensions of the rectangle?
you can think this
WL = 28
L=3w + 8
W( 3W +8) = 28
3 W^2 + 8W + = 28
3W^2 + 8W -28 = 0 (1)
3 W^2 - 6 W + !4 W -28 =0-
3 W ( W - 2 ) + 14 ( W -2) =0
(3W+ 14) ( w-2) = 0
w = 2 L = 3(2) + 8 = 14 , then LW =28
ignore the negative answer of w = -14/3
If we write all factors of 28 { 2, 4 , 7, 14)
We see that 28 = 2 * 14 , 14 = 2* 3 + 8
Therefore we can have a rectangle with area of 28 units, with 2, 14 be its dimension , and have the
property of L = 2*3 +8 (

Hi Victoria,
Area=Length x width= 28 sq in
L=8+3w
So substitute that back into the equation:
Area = L x W
28 sq in = (8+3w) x w
28 sq in = 8w +3w2
28 sq in = w (8 + 3w)
Possible factors of 28 are 2 and 14 or 4 and 7, and 1 and 28. Substituting the possibilities in the equation, we find that the correct set of factors are 2 and (8 + 3*2) or 14.

1) A=LW = 28 in
2) L = 3W + 8
Substitute L = 28/W into the 2nd equation
28/W = 3W + 8
28 = 3W^2 + 8W
3W^2 + 8W - 28 = 0
(3W+ 14)(W - 2) = 0
Note that the answer must be positive therefore the second 'zero' is the answer

A triangle has one angle measure of 55 degrees and a second angle measuring 53 degrees. What is the third missing angle measure? ______ degrees..
A triangle has a total degrees of 180, so you add 55 and 53 to get 108
then you subtract that from 180 to get 72. 72 is your answer
Answer:
72 degrees
Step-by-step explanation:
First of all, you should know that each triangle equals to 180 degrees. So just add 55 + 53 which equals 108. Then you just subtract 108 from 180 (180-108) which equals to 72 degrees.
Therefore, the third missing angle measure is 72 degrees.
Hope this helps! :)
The circumference of a circle is 53.38 centimeters.
What is the area in square centimeters? Use 3.14 for a.
Points A, B, C and D are on the circle. The ∠ACB and ∠ADB are angles subtended by the same arc AB. If arc AB measures (5x – 30)° and m∠ACB = (x + 15) °, what is m∠ADB?
Answer:
m∠ADB = 35°
Step-by-step explanation:
From the figure attached,
∠ACB and ∠ADB are the angles subtended by the same arc AB.
m(arc AB) = (5x - 30)°
m∠ACB = (x + 15)°
Since, "measure of an arc is double of the measure of the angle subtended by the arc at the circumference"
m(arc AB) = 2(m∠ACB)
(5x - 30) = 2(x + 15)
5x - 30 = 2x + 30
5x - 2x = 30 + 30
3x = 60
x = 20
By using theorem,
"Angles subtended by the same arc in the same segment of a circle are equal in measure"
Therefore, m∠ACB = m∠ADB
Since, m∠ACB = (x + 15)°
= 20 + 15
= 35°
m∠ADB = 35°

The surface area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere? Use 3.14 for π. Round your answer to the nearest hundredth. A. 696.99 cm3 B. 133.97 cm3 C. 267.95 cm3 D. 334.94 cm3
Answer:
267.95cm^3
Step-by-step explanation:
S= 4πr^2
Surface area is 200.96
π= 3.142
200.96= 4×3.142×r^2
200.96= 12.57r^2
r^2= 200.96/12.57
= 15.99
= √15.99
r = 3.9
Volume= 4/3πr^3
= 4/3× 3.142×3.9^3
= 267.95 cm^3

A number is between 40 and 45. It has prime factors of 2 and 7. What is the number?
Answer:
42
Step-by-step explanation:
42 is divisible by both 7 and 2
The number which has prime factors of 2 and 7 and in between 40 and 45 is 42.
Given that, a number is between 40 and 45. It has prime factors of 2 and 7.
What are prime factors?The process of writing a number as the product of prime numbers is prime factorization. Prime numbers are the numbers that have only two factors, 1 and the number itself.
The numbers between 40 and 45 are 41, 42, 43 and 44.
The factors of the numbers are as follows
41 = 1×41
42 = 1×2×3×7
43 = 1×43
44 = 1×2×2×11
Therefore, the number which has prime factors of 2 and 7 and in between 40 and 45 is 42.
