Answer:
3. 62.5% decrease
4. 26.2% decrease
5. 13.2% decrease
Explanation:
A percentage change is calculated from ...
percent change = ((new value) - (old value))/(old value) × 100%
When it is negative, the change is a decrease.
__
3. (24 -64)/64 × 100% = -40/64 × 100% = -62.5%, a 62.5% decrease
__
4. (4.8 -6.5)/6.5 × 100% = -1.7/6.5 × 100% ≈ -26.2%, a 26.2% decrease
__
5. (1.12 -1.29)/1.29 × 100% = -0.17/1.29 × 100% ≈ -13.2%, a 13.2% decrease
Find the 52nd term of the arithmetic sequence-8, -12, -16,...
Answer:
-212
Step-by-step explanation:
This question seems to be incrementing by steps of -4, starting at -8. To get the 52'nd term, we can simply start at the first term and add that -4 51 more times.
Assuming that negative eight is the first term then, we get:
-8 - 4 * 51
= -8 - 204
= -212
The 52nd term of the sequence will be -212.
What is a sequence?A sequence of events or things is a number of events or things that come one after another in a particular order.
Given a sequence, -8, -12, -16,...
nth term of a sequence is given by
an = a + (n-1)*d
a(-212) = -8 + (52-1)*-4
a(-212) = -8-204
a(-212) = -212
Hence, The 52nd term of the sequence will be -212.

Answer:
AB = 4
[tex]m\angle E=30^\circ[/tex]
Step-by-step explanation:
Similar shapes
Two figures are similar if the ratios of the lengths of their corresponding sides are equal. The corresponding angles are also congruent.
Being ABCD and EFGH similar, the ratio of the lengths of AB and EF is equal to the ratio of the lengths of AD and EH, thus:
[tex]\displaystyle \frac{AB}{EF}=\frac{AD}{EH}[/tex]
Solving for AB:
[tex]\displaystyle AB=\frac{AD}{EH}\cdot EF[/tex]
Since AD=6, EH=1.5, and EF=1:
[tex]\displaystyle AB=\frac{6}{1.5}\cdot 1[/tex]
AB = 4
Since angle A is congruent to angle E:
[tex]m\angle E=m\angle A[/tex]
[tex]\mathbf{m\angle E=30^\circ}[/tex]

what is the mean absolute deviation of 6 2 8 4 8 6 8 8
The mean of the data is 6.25. Then the mean absolute deviation of the data will be 1.75.
What is the mean absolute deviation?It is the average distance between each data point and the mean. Then the mean absolute deviation is given as,
[tex]\rm MAD = \dfrac{\Sigma _{i = 1}^n|x_i - \mu|}{n}[/tex]
The data is given below.
6, 2, 8, 4, 8, 6, 8, 8
The mean of the data will be given as,
μ = (6 + 2 + 8 + 4 + 8 + 6 + 8 + 8) / 7
μ = 50/8
μ = 6.25
Then the mean absolute deviation of the data will be given as,
MAD = (|6 - 6.25| + |2 - 6.25| + |8 - 6.25| + .... + |8 - 6.25|) / 8
MAD = (0.25 + 4.25 + 1.75 + 2.25 + 1.75 + 0.25 + 1.75 + 1.75) / 8
MAD = 14 / 8
MAD = 1.75

Jaxon and drake share a bag of tootsie rolls. Jaxton eats 3/5 of the bag and drake eats 5/12 of the bag. Use benchmark fractions to estimate the fraction of the bag of tootsie rolls jackson and drake ate
Answer:
[tex]\frac{49}{60}[/tex]
We can conclude that, both of them have eaten almost the complete bag of Tootsie rolls
Step-by-step explanation:
Given that:
Fraction of Tootsie rolls eaten by Jaxton = [tex]\frac{3}{5}[/tex]
Fraction of Tootsie rolls eaten by Drake = [tex]\frac{5}{12}[/tex]
Here, we have to use the Benchmark fractions to estimate what fraction of tootsie roll bags was eaten by Jaxton and Drake.
First of all, let us add the given two fractions to find the total amount of Tootsie rolls eaten by both of them together.
Total Tootsie rolls eaten by both of them =
[tex]\dfrac{3}{5} + \dfrac{5}{12}\\\\\text{Taking LCM of denominator i.e. 5 and 12 = 60}\\\Rightarrow \dfrac{3\times 12 + 5\times 5}{60}\\\Rightarrow \dfrac{49}{60}[/tex]
The most commonly used benchmark fractions are 0, [tex]\frac{1}{2}[/tex] and 1.
Here, with the fraction we can write our benchmark fractions as:
[tex]\dfrac{0}{60}, \dfrac{30}{60}, \dfrac{60}{60}[/tex]
We can see that, [tex]\frac{49}{60}[/tex] is near to [tex]\frac{60}{60}[/tex].
Therefore, we can conclude that, both of them have eaten almost the complete bag of Tootsie rolls.

Arrange the equations in increasing order of the value of their solutions.
1/4x + 5/2x - 2 = 4 - 1/4x
7.9x + x + 4 = 1.1x - 16
3.2x + 5.7 = -2.5x
10.1x - 1.6x + 44 = -7
Answer:
The answer is below
Step-by-step explanation:
a)
1/4x + 5/2x - 2 = 4 - 1/4x
collecting like terms:
(1/4)x + (5/2)x + (1/4)x = 4 + 2
3x = 6
x = 6/3
x = 2
b)
7.9x + x + 4 = -1.1x - 16
collecting like terms:
7.9x + x + 1.1x = - 16 - 4
10x = -20
x = -2
c)
3.2x + 5.7 = -2.5x
collecting like terms:
3.2x + 2.5x = 5.7
5.7x = 5.7
x = 1
d)
10.1x - 1.6x + 44 = -7
collecting like terms:
10.1x - 1.6x = -7 - 44
8.5x = -51
x = -6
Hence the equations in increasing order of the value of their solutions is:
10.1x - 1.6x + 44 = -7
7.9x + x + 4 = -1.1x - 16
3.2x + 5.7 = -2.5x
1/4x + 5/2x - 2 = 4 - 1/4x

Answer:

Step-by-step explanation:
Answer:
A. Sugar was central to people’s daily lives, work, and economy.
Step-by-step explanation:
Slavery was abolished in the British Empire in 1833, thirty years before the Emancipation Proclamation in the United States. But even after they freed their slaves, the sugar plantation owners were desperate to find cheap labor to cut cane and process sugar. So the British owners looked to another part of the empire—India—and recruited thousands of men and women, who were given five-year contracts and a passage back.
so that means
My great-grandparents had come from India to Guyana—then British Guiana—in the late nineteenth century to work on the sugar plantations. Sugar was the backbone of the British Empire at that time. The demand was huge, for sugar had gone from being a luxury that only kings could afford to a necessity. Even the poorest of London shopgirls took sugar in their tea.

The Holcombe family went out to dinner
The meal cost $54.65.
The sales tax is 8% of the meal.
The tip was 18% of the meal and tax
There are 5 people in the Holcombe family
What was the cost per person for the meal, including sales tax and tip?
Answer:
$13.77 per person in the family
Step-by-step explanation:
Cost of the meal = $54.65
Sales tax rate = 8%
Sales tax amount = 8% of $54.65
= 8/100 × 54.65
= 0.08 × 54.65
= $4.372
Tip = 18% of $54.65
= 18/100 × 54.65
= 0.18 × 54.65
= $9.837
Total cost of the dinner = Cost of the meal + Sales tax amount + Tip
= $54.65 + $4.372 + $9.837
= $68.859
There are 5 people in the Holcombe family
What was the cost per person for the meal, including sales tax and tip?
cost per person for the meal, including sales tax and tip = Total cost of the dinner / total number of people in the family
= $68.859 / 5
= $13.7718
Approximately
$13.77 per person in the family

Answer:
No, they are not inverses.
Step-by-step explanation:
To find out if this are inverses we will have to switch the x and y in one of the equations. Let's do it with the second equation:
(Remember that f(x)/g(x) and y are virtually the same)
y = -4x + 2
Switch x and y
x = -4y + 2
Now solve for y
x - 2 = -4y
[tex]-\frac{x}{4} + \frac{2}{4} = y\\-\frac{x}{4} + \frac{1}{2} = y[/tex]
Therefore, the 2 functions in the question are not inverses of each other because the actual inverse has a negative in front of the -x/4.
