Answer:
43.205 in expanded form:B. 40 + 3 + 0.2 + 0 + 0.005Explanation:
The number 43 is basically 40+3
We read "43" as "forty three", in which you can think of having 40 and then an additional 3 on top of that to get 40+3 = 43 overall.
As for the decimal portion, we do the same sort of thing.
The 0.205 breaks up into 0.2 + 0.005
0.2 = 2 tenths
0.005 = 5 thousandths
So that's why 43.205 breaks down into 40+3+0.2+0+0.005; each place value digit corresponds to a term in that expanded sum.

What is the rate of change over the interval [-1,2] for f(x)= 4x +1
Answer:
4
Step-by-step explanation:
To find the average rate of change, we have to plug in the difference between the intervals with this equation: f(b) - (fa) / x₂ - x₁
Let f(a) = f(-1) = 4(-1) + 1
f(b) = f(2) = 4(2) + 1
x₂ = 2
x₁ = -1
[4(2) + 1 - (4(-1) + 1)] / [2 - (-1)]
[8 + 1 + 4 - 1] / [3]
12 / 3 = 4

Is 3 to the second power + 3 to the 3rd power equal to 3 to the 5th power explain
Answer:
They are not equal.
Step-by-step explanation:
Hi there!
[tex]3^2+3^3[/tex] is not equal to [tex]3^5[/tex]. When two powers with the same base are added together, we cannot add the exponents to get the answer.
We can only add exponents to get the answer when two power with the same base are multiplied.
[tex]3^2+3^3\\= 9+27\\=36[/tex]
[tex]3^5\\=243[/tex]
They are not equal.

Answer:
7. 240
8. 12, 24, and 36
9. 48
10. 12
Step-by-step explanation:
7. Do the multiple of 24, 48, and 80. Then find the LEAST common number that all three numbers have in common. (Answer: 240)
8. Do the multiple of 3, 4, and 6. Then find 3 LEAST common numbers that all three numbers have in common. (Answer: 12, 24, and 36)
9. Do the multiple of 12, 16, and 24. Then find the LEAST common number that all three numbers have in common. (Answer: 48)
10. Do the multiple of 2, 3, and 4. Then find the LEAST common number that all three numbers have in common. (Answer: 12)
STEPS ON HOW TO SOLVE:
Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 3, 4, and 6. Write this prime number(2) on the left of the given numbers(3, 4, and 6), separated as per the ladder arrangement.
Step 2: If any of the given numbers (3, 4, 6) is a multiple of 2, divide it by 2 and write the quotient below it. Bring down any number that is not divisible by the prime number.
Step 3: Continue the steps until only 1s are left in the last row.
The LCM of 3, 4, and 6 is the product of all prime numbers on the left, i.e. LCM (3, 4, 6) by division method = 2 × 2 × 3 = 12.

Answer:
y = 3/8x + 3
Step-by-step explanation:
Parallel lines have the same slope. In given equation, y = 3/8x + 5, the slope, m = 3/8. Therefore, the other line must also have the same slope.
Using the slope, m = 3/8, and the given point, (16, 9), substitute these values into the slope-intercept form:
y = mx + b
9 = 3/8(16) + b
9 = 6 + b
9 - 6 = 6 - 6 + b
3 = b (this is the y-intercept).
Now that we have our slope, m = 3/8, and the y-intercept, b = 3:
The equation of the line parallel to y = 3/8x + 5 is:
y = 3/8x + 3

Please help! Geometry practice was lines cut by a transversal. What is the value of X?
Answer:
x = 70
Step-by-step explanation:
1. First, we need to know that the angle with 45 degrees and the angle with (2x-5) degrees are same-side interior angles, meaning they add up to 180 degrees. The equation of this can be written as so: [tex]2x-5+45= 180[/tex]
2. (Solving)
Step 1: Combine like terms.
[tex](2x) +(-5+45) = 180[/tex] [tex]2x + 40 = 180[/tex]Step 2: Subtract 40 from both sides.
[tex]2x + 40 - 40 = 180 - 40[/tex] [tex]2x = 140[/tex]Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{140}{2}[/tex] [tex]x = 70[/tex]Step 4: Check if solution is correct.
[tex]2(70) - 5 + 45 = 180[/tex] [tex]140 - 5 + 45 = 180[/tex] [tex]135 + 45 = 180[/tex] [tex]180 = 180[/tex]Therefore, x = 70.
In a class, 4/7 of the total number of students are boys. If 2/5 of the boys or 8 boys are wearing spectacles, calculate the number of girls in the class.
Answer:
15
Step-by-step explanation:
let total num of boys be X.
then,2/5 of X = 8
2 ×x = 40
X = 20
Now, let the total num of students be y,then we get,
4/7 of y = 20
4 × y = 140
y = 35
similarly, total num of girls = total num of students - total num of boys
= 35 - 20
= 15 ans
How to check 20p+75=35p+30
[tex]20p+75=35p+30[/tex]
Step 1: Subtract [tex]20p[/tex] from both [tex]p[/tex] sides
[tex]\:\:\:\:20p+75=35p+30\\-20\:\:\:\:\:\:\:\:\:\:\:\:-20[/tex]
20 - 20 = 0, so it is canceled out. 35 - 20 = 15, don't forget the [tex]p[/tex]!
[tex]75=15p+30[/tex]
Step 2: Subtract 30 from both sides
[tex]\:\:\:\:75=15p+30\\-30\:\:\:\:\:\:\:\:\:\:\:\:-30[/tex]
30 - 30 = 0, so it is canceled out. 75 - 30 = 45.
[tex]45=15p[/tex]
Step 3: Divide both sides by 15
[tex]\frac{45}{15} =\frac{15p}{15}[/tex]
15 ÷ 15 cancels out. 45 ÷ 15 = 3.
[tex]20p+75=35p+30\quad :\quad \boxed {\bold {p=3}}[/tex]

Please help with this math problem! Will give brainliest! :)
Answer:
9
Step-by-step explanation:
All triangles (3 sided polygons) have angles added up to 180, so we can do the following:
(7x-1) + (7x+8) + (5x+2) = 180° - equation
7x-1 + 7x+8 + 5x+2 = 180° - "distribute"
19x - 1 + 8 + 2 = 180° - combine the x terms
19x + 9 = 180° - combine the integer terms
19x = 171 - subtract 9 form both sides
x = 9 - divide both sides by 19
The stock market drops 18 points.
or stocks, one point equals one dollar. So when you hear that a stock has lost or gained X number of points, it is the same as saying the stock has lost or gained X number of dollars.
Using points to describe share price gains, or declines, is generally done to describe short-term results, such as for the day or week.
Although one point always equals one dollar, the percentage value of a one-point movement can be different for two companies. Points refer only to the dollar amount that has changed, not the percentage. Two stocks can lose the same number of points but very different percentages.
