90 is what percent of 81?
Step-by-step explanation:
did you change the reference number ?
I think the original question was "90 is how many % of 80 ?"
now it is 81.
in % calculations the most important things to identify :
what are 100% (or any other reference % level).
then what is 1%.
and then multiply this 1% by the desired number of % or divide the target number by this 1% to find out how many % the target number is.
in our case here
100% = 81
1% = 100%/100 = 81/100 = 0.81
how many % are 90 ?
well, as many as how often 1% fits into these 90 :
90/0.81 = 111.111111111... %
when the reference was 80, then we had
90/0.8 = 112.5%

1. A rectangular box has dimensions 4 feet by 3 feet by 5 feet. Increasing each
dimension by the same amount yields a new box with twice the volume of
the old box. Determine the new dimensions of the box.
The new dimensions of the box are 5 feet, 4 feet, and 6 feet.
Given:
A rectangular box has dimensions of 4 feet by 3 feet by 5 feet.
So, Length = 4 feet ,width = 3 feet and height = 5 feet.
Volume of rectangular box = length × width × height
= 4 × 3 × 5 = 60 feet³
Now, increasing each dimension by the same amount yields a new box.
Let the increase in dimension be x feet.
The dimensions of the new box are,
Length = (4 + x) feet ,width = (3 + x) feet and height = (5 + x) feet.
Volume of new box = length × width × height
= (4 + x) (3 + x) (5 + x)
It is given that the volume of the new box is twice the volume of the old box, 2 × 60 feet³ = 120 feet³
So, equate the volume to find the value of x.
(4 + x) (3 + x) (5 + x) = 120
(12 + 7x + x²) (5 + x) = 120
60 + 12x + 35x + 7x² + 5x² + x³ = 120
60 + 47x + 12x² + x³ = 120
x³ + 12x² + 47x - 60 = 0
x = 1
Hence each dimension was increased by 1 foot.
The new dimensions of the box are 5 feet, 4 feet, and 6 feet.

Talia took the bus from her home to the bank and then walked back to her home along the same route. The bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. To determine the time, x, that it took Talia to walk home, she used the equation
40(0.9 – x) = 5x.
The time of Trip 2 is
hours.
The distance of Trip 1 is
km.
Answer:The time of Trip 2 is
⇒ 0.8 hours.
The distance of Trip 1 is
⇒ 4 km.
The time of Trip 2 is 0.8 hours
The distance of trip 1 is 32 km
Given,
The speed of the bus = 40 km/h
Talia's walked at a speed = 5 km/h
To determine the time,x for her walk here used the equation; 40(0.9 – x) = 5x.

Given;
We are given a parallel pair of lines m and n, and a transversal that cuts both lines.
Required;
We are required to find the value of x.
Step-by-step solution;
When a pair of parallel lines are cut by a transversal, the angle formed by the point of intersection of one line and the transversal is equal to that formed by the other line and the transversal when they both lie on the same side of the transversal.
This means on the diagram given;
This means angle 167 on line n is equal to angle 167 on line m. These are called corresponding angles.
The same applies to angle x on the line m and the other angle on line n. They both are also corresponding angles.
Next, take note that angles that lie on either side of a vertex where two lines intersect are called vertically opposite angles (or just opposite angles).
Therefore, angle x = 167 and angle 167 = x.

Answer:
20
Step-by-step explanation
We need to find the multiples of 10 and 20 (multiples of 10 = 10, 20, 30, 40; multiples of 20 = 20, 40, 60, 80) and choose the smallest multiple that is exactly divisible by 10 and 20, i.e., 20.
Answer:
20
Step-by-step explanation:
First, find the factors of both 10 and 20
Factors of 10: 1, 2, 5, 10
Factors of 20: 1, 2, 4, 5, 10, 20
Notice any common factors?: 1, 2, 5, 10
Now multiply the greatest common factor, 10, with another even number to hopefully get 20: 10*2=20.
Hence, the least common multiple is 20.
In 3–5 sentences, explain why the moon appears to be less bright than the sun despite its very close distance to Earth. PLEASE DO NOT COPY OTHER PEOPLE AND RIGHT THISBased on scientific observations and findings, the reasons the moon appears to be less bright than the sun despite its very close distance to earth are the following:
Moon doesn't produce its light but rather takes or reflects the light from the Sun.
Moon only reflects about 12 percent maximum of lights that shines on it from the sun.
Externally, Moon is made of dark-colored soil often referred to as lunar soil. This is unlike the Sun which is made of hydrogen and helium, whose atoms are very light.
Also, Sun is about 400 times bigger than the Moon.
Hence, in this case, it is concluded that there are many reasons the moon appears to be less bright than the sun despite its very close distance to earth. MAKE IT SIMPLE
Answer:
Since the moon has no atmosphere, all wavelengths of sunlight reach the ground by traveling straight through space. Our sun appears white because it produces all visible wavelengths approximately equally. The sun will appear the same size whether viewed from Earth or the Moon since Earth and the moon are relatively close to the sun. The sun and moon both have an apparent size of one-half of a degree when viewed from Earth.

Store A sells 2 bags of chips for $2.50. Store B sells 3 bags of chips for $3.25. Which store offers the better deal?
Answer:
Store B
Step-by-step explanation:
Since the lowest common multiple of 2 and 3 is 6, so let's find the cost of 6 bags of chips from each store.
Store A
cost for 6 bags of chips
= 3(2.5)
= $7.50
Store B
cost for 6 bags of chips
= 2(3.25)
= $6.50
Since store B offers a cheaper price for 6 bags of chips, it offers a better deal.
Alternatively, you could work out the cost of each bag of chips for both stores.

Describe what is happening to the variables here (hint: time is almost always on the x-axis). Is this a variation equation?
If Lisa and Joey put the same amount of money every month in the savings account for David's future and the situation is plotted in a graph where time is on the x-axis, then there will be straight line with a constant slope.
As per the question statement, Lisa and Joey just became parents to their son, David and they decided to start a savings account for their newborn's future, where they agreed to put an equal amount of money every month.
We are required to determine the condition of the variables if the above-mentioned situation is plotted into graph and the account gets constantly filled with money as David grows older.
To solve this question, first let us consider the time to be plotted on the X-axis (As mentioned in question statement that "Time" is almost always on the x-axis) and the money collected to be plotted on the Y-axis.
Since, an equal amount of money is put into the account every month, therefore, taking 1 month as unit time to plot our graph, the money will grow diagonally in a straight line with a constant slope. Hence, both the variables (abscissa and ordinates) will increase on a constant ratio along the first quadrant.

The equation of the line that passes through the point (-9, 2) and is perpendicular to the line 10x - 5y = 6 is y = - 1 / 2 x - 5 /2
How to find equation of a line?The equation of a line can be represented in slope intercept form.
Therefore,
y = mx + b
where
m = slopeb = y-interceptTherefore, the equation of the line is perpendicular to 10x - 5y = 6.
5y = 10x - 6
y = 2x - 6 / 5
