What is 4,785 rounded to the nearest thousand?
Answers
You'd round it up, as 7 is above 5.
The rule is, if the number is 4 or less you round down but if it is 5 or above you round up.
This makes your answer 5000.

Twice a number (x) is less then 10
Answers
Twice x would be 2 * x, because it's x two times, which would be said as 2x.
Less then 10 would be <10, because the sign (<) is the less than sign and 10 follows it.
So it would be 2x < 10.

We can rewrite the exponential expression in scientific notation as follows:
[tex] 7.3579 E8 = 7.3579 * 10 ^ 8
[/tex]
Then, to write the number in its standard form, we move the decimal point 8 spaces to the right. This is because the exponent is positive.
We have then:

Since 1970, the # (in thousands) of males M and females F attending institutes of higher education can be modeled by: M=0.091t^3-4.8t^2+110+5,000 and F=0.19t^3-12t^2=350t+3,600 where t is the number of yrs since 1970. Write a model for the total # of people attending institutes of higher education.
Answers
The total number of people attending higher education institutions is modeled by T = 0.281t^3 - 16.8t^2 + 460t + 8,600, representing the sum of the models for males and females attending colleges.
Explanation:To answer the student's query regarding the total number of people attending institutes of higher education, we need to create a model that includes both the number of males and females attending as described by their respective equations. The model for the number of males attending college is given by M = 0.091t^3 - 4.8t^2 + 110t + 5,000, and the model for the number of females is F = 0.19t^3 - 12t^2 + 350t + 3,600. To find the total number of students, T, we simply add the two models together: T = M + F.
Therefore, the model for the total number of people attending institutes of higher education is:
T = (0.091t^3 - 4.8t^2 + 110t + 5,000) + (0.19t^3 - 12t^2 + 350t + 3,600)
Combining like terms, we get:
T = (0.091t^3 + 0.19t^3) - (4.8t^2 + 12t^2) + (110t + 350t) + (5,000 + 3,600)
Which simplifies to:
T = 0.281t^3 - 16.8t^2 + 460t + 8,600
This equation represents the total number of students, in thousands, attending institutes of higher education t years since 1970.
At 5 a.m., the temperature at an airport was −9.4°F . Six hours later, the temperature was 2.8°F . Which expression represents the total temperature change over the six hours?
I need help with this now!
Answers
Answer:
(-9.8 + x) = 2.8
Step-by-step explanation:
The temperature at an airport at 5:00 am was -9.4° F.
Six hours later the temperature was 2.8° F.
Let temperature change in the 6 hours is = x° F
Then the temperature after six hours from -9.8° F will be = (-9.8 + x)° F
And the expression representing the change will be
(-9.8 + x) = 2.8
How many people must attend the third show so that the average attendance per show is 3000 write an equation too
Answers
The third show must be attended by 3500 people.
To find the number of people that must attend the third show so that the average attendance per show is 3000, we can use the concept of averages.
The average attendance per show is the sum of the attendances divided by the number of shows.
In this case, we have attended 1 show by 2580 people, 2 shows by 2920 people, and the attendance for the third show is x people. So, the equation to represent the average attendance per show of 3000 is:
(2580 + 2920 + x) / 3 = 3000
To solve this equation, we can multiply both sides by 3 to eliminate the denominator and get:
2580 + 2920 + x = 9000
Then, we combine like terms:
5500 + x = 9000
Finally, we subtract 5500 from both sides to isolate x:
x = 3500
Therefore, for the average attendance per show to be 3000, the third show must be attended by 3500 people.
The probable question may be:
How many people must attend the third show so that the average attendance per show is 3000 write an equation too
1 show is attend by 2580 people,
2 show is attend by 2920 people,
3 show is attend by x people.
correct answer is x=3500

The main cable of a suspension bridge forms a parabola, described by the equation y = a(x - h)2 + k, where y is the height in feet of the cable above the roadway, x is the horizontal distance in feet from the left bridge support, a is a constant, and (h, k) is the vertex of the parabola. At a horizontal distance of 30 ft, the cable is 15 ft above the roadway. The lowest point of the cable is 6ft above the roadway and is a horizontal distance of 90 ft from the left bridge support. Which quadratic equation models the situation correctly? y = -0.0025(x - 90)² + 6y = -0.0025(x - 30)² + 15✔ y = 0.0025(x - 90)² + 6y = 0.0025(x - 30)² + 15
The main cable attaches to the left bridge support at a height of 26.25 ft.The main cable attaches to the right bridge support at the same height as it attaches to the left bridge support. What is the distance between the supports?Answers
Answer:
The equation that models this situation correctly is C. y = 0.0025(x-90)² + 6.
Step-by-step explanation:
To find the quadratic equation that best models this equation, the only piece of information we need is "The lowest point of the cable is 6ft above the roadway and is a horizontal distance of 90 ft from the left bridge support."
The keyword lowest tells us the value is a minimum. Therefore, the parabola must be a positive one, because negative parabolas have maximum values. This disqualifies answer choices A and B because they have negative a values.
We also know the vertex occurs at (90, 6) because this is where the lowest point is. Therefore, the equation should be y = 0.0025(x-90)² + 6. (Note: the information about point (30, 15) is not relevant to the problem.)
Give an example of addition problem in which you would and would not group the addends differently to add
Answers
In a problem like 3+5+7, I would group the addends differently (3+7+5). This is because, in the first problem you would first add together 3+5 to get 8, and then you would add 8+7 to get 15. However, if you were to add 3+7 first, you would get 10. 10+5 is much easier to add than 8+7.
Answer:
The numbers which have unit digit Zero for a two digit number, and for three digit number ones and tens place should be equipped with zero,So on..... does not require addends to group together.
For example, addition problem in which you would not regroup addends
→ 10+20+30
→ 30 +40 +50
→ 100+200+300
And Addition Problems in which you will regroup addends
→ 17 +5 +3=(17+3)+5=20+5=25
→ 4+9+6=(4+6)+9=10+9=19
→ 13+19+17=(13+17)+19=30+19=49

Which statement best defines a universal law
A. It is in fact some of the time
B. It is in effect at all times
C. It changes over time
D. It operates only under specific times
Answers
Explanation:
By definition, a universal law is immutable, meaning that it does not change and it is in effect at all times.
This definition should be appled within the scope of what "universal" means.
For example, the law of "Cause and Effect" is stated in physics by Newton's third law: To every action, there is an equal and opposite reaction.
Discussion:
Our perception of the universe is limited usually to our solar system, within a physical and material universe. We cannot be certain that our accepted universal laws apply in the same manner in a nonmaterial or spiritual universe.
According this explanation, the following statement best defines a universal law:
B. It is in effect at all time.

Answers
Answer:
$59.13355 ≈ $59.14
Step-by-step explanation:
Marked Price = $78.95
Discount @ 30% = 0.30 x $78.95
= $23.685
Selling Price = Marked Price - Discount
= $78.95-$23.685
= $55.265
Sales tax @ 6% = 0.06 x $55.265
= $3.3159
Local Option Tax @ 1% = 0.01 x $55.265
= 0.5526
Hence Billing amount = Selling Price +Sales tax + Local Option Tax
= $55.265 + $3.3159+$0.5526
= $59.13355
≈ $59.14

Dog's weight rounded to the nearest ten pounds
Answers
The dog's weight rounded to the nearest ten pounds is 80 pounds.
The dog's weight, 76 pounds, can be rounded to the nearest ten pounds.
To round to the nearest ten pounds, we look at the digit in the ones place. If the digit is 0, 1, 2, 3, or 4, we round down to the nearest ten. If the digit is 5, 6, 7, 8, or 9, we round up to the nearest ten.
In this case, the digit in the ones place is 6. Since 6 is greater than 5, we round up to the nearest ten.
So, the dog's weight rounded to the nearest ten pounds is 80 pounds.
