Answer:
-0.048
Step-by-step explanation:
-30 * -1/5 = 6
6 * -1/5 = -1.2
(Remember -30 is first term so we subtract 1 from 5 in the exponent)
-30 * (-1/5)^4 = -0.048

$5647.50
$11,475
$95.63
RIGHT ANSWER BRAINLYEST
Answer:
$5647.50
Step-by-step explanation:
Formula for interest => I = Prt
substitute => I = (4500)(0.085)(3)
I = 1147.5
Add interest to our principle value => 4500 + 1147.5
Thus, our answer: $5647.50

what is 2/10 divided by 2/4
Given:
[tex]\dfrac{2}{10}[/tex] divded by [tex]\dfrac{2}{4}[/tex].
To find:
The solution for the given division problem.
Solution:
We have, [tex]\dfrac{2}{10}[/tex] divded by [tex]\dfrac{2}{4}[/tex]. It can be written as
[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{10}\times \dfrac{4}{2}[/tex]
[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2\times 4}{10\times 2}[/tex]
[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{8}{20}[/tex]
[tex]\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{5}[/tex]
Therefore, the solution for the given division problem is [tex]\dfrac{2}{5}[/tex].
Parallelogram FGHJ was dilated and translated to form similar parallelogram F'G'H'J'. What is the scale factor of the dilation?
Answer:
The scale factor is 4
Step-by-step explanation:
Given
See attachment for parallelograms
Required
Determine the scale factor (k)
Using sides FG and F'G' as a point of reference:
[tex]FG = 2\ units[/tex]
[tex]F'G' = 8\ units[/tex]
The scale factor (k) is calculated as:
[tex]k = \frac{New}{Original}[/tex]
[tex]k = \frac{F'G'}{FG}[/tex]
[tex]k = \frac{8\ units}{2\ units}[/tex]
[tex]k = 4[/tex]

Answer:
A
Step-by-step explanation:
The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are [tex]x[/tex] and [tex]y[/tex].
To find the constant of proportionality, all we have to do is divide any value of [tex]y[/tex] by its corresponding value of [tex]x[/tex]. Let's take the values in the first row of the table. We know that [tex]x=2[/tex] and [tex]y=12[/tex], so the constant of proportionality is [tex]\frac{y}{x}=\frac{12}{2} =6[/tex]. Hope this helps!
A 92-inch is cut into two pieces. One piece is three times the length of the other. Find the length of the shorter piece. The shorter piece is nothing inches long.
Answer:
23 inches
Step-by-step explanation:
Let us represent
First piece = x
Second piece = y
A 92-inch is cut into two pieces.
x + y = 92
One piece is three times the length of the other.
x = 3y
Find the length of the shorter piece.
Hence:
x + y = 92
x = 3y
3y + y = 92
4y = 92
y = 92/4
y = 23 inches
Solving for x
x + y = 92
x + 23 = 92
x = 92 - 23
x = 69 inches
The shorter piece is 23 inches long.

n/9 + 2/3 = -2/3
Answer:
n = - 12
Step-by-step explanation:
n/9 + 2/3 = - 2/3
n/9 = - 2/3 - 2/3
n/9 = - 4/3
n = 9(- 4/3)
n = -36/3

Answer:
[tex]d. \: \: \: 25 {x}^{6} [/tex]
Step-by-step explanation:
Given,
Side of the square
[tex] = 5 {x}^{3} [/tex]
Therefore, area of the square = side × side
[tex] = {5x}^{3} \times 5 {x}^{3} [/tex]
[tex] = 5 \times 5 \times {x}^{3 + 3} [/tex]
[tex] = 25 {x}^{6} [/tex]

Landon owns 16 baseball cards, which is 4 times as many as Phillip owns.
The equation 4p=16 represents this situation where p is the number of baseball cards Phillip owns.
Which number line represents the solution to the equation?
Answer:
B
Step-by-step explanation:
i'm probably wrong but based on the information they give you the most likely answer has to be B. ok- well if you think abt it landon has 16 cards and that's 4 times as many as phillip has. so, phillip's cards could range anywhere between 4 and 16-
sorry if i'm incorrect :/ hope you get a good score or whatever tho

Mr John leased two thousand fifty meter square of land from the city administration. He gave one eighth of his land to his brother. How many meters square did he have left?
Answer:
1793.75 m²
Step-by-step explanation:
Given that :
Total amount of land leased = 2050 m²
Fraction of land given to brother = 1/8
Amount of land given to brother :
1/8 * 2050 = 256.25 m²
Amount of land left :
2050 m² - 256.25 m²
= 1793.75 m²
Kalyan's present age is one third his mothers present age . If the mothers age was 5 times his age 6 years ago ,what are their present age
Current ages:
Let Kaylan's present age be x years
Since his age is a third of his mother's present age:
mother's age * (1/3) = Kaylan's age
mother's age * (1/3) = x
mother's age = 3x [multiplying both sides by 3]
Kaylan's mother's age would be 3x years
Their ages 6 years ago:
Kaylan's age: x-6 years
Mother's age: 3x-6 years
We are told that mother's age was 5 times Kaylan's age, 6 years ago. So,
5*(Kaylan's age 6 years ago) = (Mother's age 6 years ago)
replacing the values
5(x - 6) = 3x-6
5x - 30 = 3x-6
2x - 30 = -6 [subtracting 3x from both sides]
2x = 24 [adding 30 on both sides]
x = 12 [dividing both sides by 2]
Hence, x = 12
Kaylan's present age(x) = 12 years
Mother's present age(3x) = 3*12 = 36 years
