We have,
To round 0.078 to the nearest thousandths, we look at the digit in the thousandth place, which is the third decimal place.
The digit in the thousandth place is 8.
Now,
We will look at the digit preceding the digit in the thousandth place.
We see that,
The digit is zero which is less than 5.
So,
0.078 rounding to the nearest thousandth is 0.078 itself.
Therefore,
Rounding 0.078 to the nearest thousandths gives us 0.078.

Every 2/3 hour, Harris can sew 1/6 pair of jeans. What is Harris's rate in pairs of jeans per hour? Drag and drop the correct value into the box.
The rate in pairs of jeans per hour is 1/4
For every 2/3 hour Harris can sow 1/6 pair of jeans
Therefore the rate of Harris's jeans in pairs can be calculated as follows
= 1/6 ÷ 2/3
= 1/6 × 3/2
= 3/12
= 1/4
Hence the rate in pairs of jeans per hour is 1/4

Given that, a person starts climbing a mountain, and then walks across a plateau, before finishing her climb to the top.
An airplane reaches its cruising altitude.
What is cruising altitude?The height in the sky at which an airplane stays for most of a flight.
Cruise altitude is usually where the higher ground speed is balanced against the decrease in engine thrust and efficiency at higher altitudes.
In the graph a plateau and cruising altitude of a function is a part of its domain where the function has constant value.

A city ordinance in River City requires that there be a police officer for every 470 residents. If the population of River city is 410,300, what is the minimum number of police officers needed?
To meet the city ordinance's requirement, River City needs at least 874 police officers, determined by dividing the population of 410,300 by 470 and rounding up to the nearest whole number.
To determine the minimum number of police officers needed for the population of River City, we simply divide the city's population by the number of residents per officer as required by the ordinance. In this case, we divide 410,300 residents by the ordinance's requirement of one officer for every 470 residents.
Calculation: 410,300 residents / 470 residents per officer = approximately 873.19.
Since we cannot have a fraction of a police officer, we round up the number to the nearest whole number to ensure that we meet the minimum requirement. Therefore, River City needs at least 874 police officers.
Jacob has 16 toy cars.3/8 of the cars are red and the rest are blue.how many cars are blue
Answer:
The number of blue toy cars that Jacob has is 10.
Solution:
Given:
Total number of toy cars = 16
Number of red cars = [tex]\frac{3}{8}[/tex] of the total number of cars = [tex]\frac{3}{8}\times16[/tex]
On dividing 8 and 16 we get 2 i.e. [tex]3\times2=6[/tex]
[tex]\therefore[/tex] Total red cars = 6
To find: the number of blue toy cars
Number of blue toy cars = Total number of toy cars - Number of red cars
[tex]\Rightarrow 16-6=10[/tex]
Hence, blue cars = 10

The profit-maximizing quantity for Doggies Paradise Inc. is determined by comparing marginal revenue and marginal cost for each output level and is found to be at five units, which results in a profit of $40.
Explanation:Profit Maximization CalculationTo calculate the profit-maximizing quantity for Doggies Paradise Inc., we construct a table showing total revenue, marginal revenue, total cost, and marginal cost for each output level from one to five units. Given the price of $72 per dog coat, the fixed costs of $100, and the various total variable costs for each output level, we can determine the profit-maximizing quantity by comparing marginal revenue and marginal cost.
Calculate total revenue by multiplying the number of units by the price ($72).Calculate total cost by adding fixed costs ($100) to the total variable costs for each output level.Determine marginal revenue and marginal cost for each additional unit produced.Identify the output level where marginal revenue equals marginal cost; this is the profit-maximizing quantity.Subtract total cost from total revenue to find profits at this output level.If Doggies Paradise Inc. produces and sells five units, they will achieve a profit of $40, as total revenue will be higher than total costs, indicating that the fifth unit is adding to the profits.

Consider a civilization broadcasting a signal with a power of 2.0×104 watts. The Arecibo radio telescope, which is about 300 meters in diameter, could detect this signal if it is coming from as far away as 141 light-years. Suppose instead that the signal is being broadcast from the other side of the Milky Way Galaxy, about 70000 light-years away.
For light: Inverse Square Law
The signal is weaken by the inverse square of the
difference of distances this means that one over the square of the
difference.
Therefore, 70000LY / 141 LY =496.45 and that squared =246462.602 times less signal, or 1/246462.602.
2 For a circular telescope like the
Arecibo radio telescope that equals Pi times the radius squared. Sensitivity
of the telescope depends on its area.
The new telescope needs 246462.60 times that area to have
enough sensitivity
(150 x 150 x Pi) = 70 685 sq m area for the Arecibo telescope
and that times 246462.60
= 1.74212 x 10^10
What is the diameter of a circle with that area?
1. Divide the area by Pi = 5.548156 x 10^9
2. Take the square root of the result to find the radius = 74485.94293
3. Multiply by 2 to find the diameter = 148971.886

Which transformations will produce similar, but not congruent, figures?
A) Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle M"N"O".
B) Triangle MNO is reflected across the x-axis and then translated 9 units down to form triangle M"N"O".
C) Triangle MNO is reflected across the x-axis and then rotated 90° clockwise to form triangle M"N"O".
D) Triangle MNO is reflected across the y-axis and then rotated 180° clockwise to form triangle M"N"O".
Answer: A) Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle M"N"O".
Step-by-step explanation:
We know that we prefer rigid motions to create congruent images.
There are four kinds of rigid motions:
1) translation 2) reflection 3) rotation 4) glide reflection.
But a dilation is a transformation that creates an image having similar shape as the original, but with a different size.
So it does not create congruent images.
Hence transformations will produce similar, but not congruent, figures is :
Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle M"N"O".

The volume of a cube depends on the length of its sides. This can be written in function notation as v(s). What is the best interpretation of v(3) = 27?
Answer:
Step-by-step explanation:
The volume of the cube depends on the length of its sides.
Volume can be represented by the function
V(s) = s³
Where s represents the length of one side.
Now V(3) = 27
or V(3) = 3³ will represent the volume of the cube with a side of length 3 unit.
