384 the next greatest number of tens is 390.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
Note that the tens place is two moves to the right of the decimal point (if it exists).
To determine the greatest number to the nearest ten (nearest 10),
we use the place of the whole number to determine whether the tens place rounds up or stays the same.
The tens place (8) then look at the digit to the right (4):
⇒ 384
The digit to the right (4) is 4 or below. So, we replace it with a 0 (zero) to get 390 as the answer.
So, 384 the next greatest number of tens is 390.

Gasoline at a particular gas station costs $2.78 per gallon. If Cory buys $18 of gas, how many gallons did he buy?
Answer:
Cory bought 6.474 gallons of gasolline.
Step-by-step explanation:
The total cost of gasoline ([tex]C[/tex]), measured in dollars, is given by the following expression:
[tex]C = n\cdot c[/tex]
Where:
[tex]n[/tex] - Amount of gasoline, measured in gallons.
[tex]c[/tex] - Unit cost, measured in dollars per gallon.
Given that [tex]C = \$\,18[/tex] and [tex]c = \$\,2.78\,\frac{1}{gal}[/tex], the amount of gasoline is cleared and calculated:
[tex]n = \frac{C}{c}[/tex]
[tex]n = \frac{\$\,18}{\$\,2.78\,\frac{1}{gal} }[/tex]
[tex]n = 6.474\,gal[/tex]
Cory bought 6.474 gallons of gasolline.

Find the distance between the two points in simplest radical form.
(3,7) and (9,9)
Answer:
The answer is
[tex]2 \sqrt{10} \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(3,7) and (9,9)
The distance between them is
[tex]d = \sqrt{ ({3 - 9})^{2} + ({7 - 9})^{2} } \\ = \sqrt{ ({ - 6})^{2} + ({ - 2})^{2} } \\ = \sqrt{36 + 4} \\ = \sqrt{40} [/tex]We have the final answer as
[tex]2 \sqrt{10} \: \: units[/tex]Hope this helps you
How many solutions exist for 2 |x - 1| = 8?
A. 0
B. 1
C. 2
D. 3
Answer:
I believe the correct answer is C.
Step-by-step explanation:
So to get 0 solutions the absolute value would have to equal a negative number. To get 1 solution the absolute value would have to equal 0. To get 2 solutions the absolute value would have to equal a positive number.
2 |x - 1| = 8
divide by 2
|x - 1| = 4
The absolute value equals a positive so it has 2 solutions.

Step-by-step explanation:
Given a standard day, at what altitude is the true airspeed of an aircraft approximately twice of what the airspeed indicator reads
Answer:
40000ftMSL
Step-by-step explanation:
We know that airspeed is measured using a pilot tube
And the air pressure is a function of density given as
Pressure= 1/2 xdensityx V²
So at 40,000ftMSL
Is this is replaced for V in the equation then the density of air will be 1/4 that of sea level
So since we are deriving velocity from pressure and pressure is 1/4 so the velocity Will be half of its pressure since velocity is squared from The equation above
one number is 7 more than twice the other number. if the sum of the two numbers is 19, find the two numbers
Answer:
4 and 15
Step-by-step explanation:
Let the two numbers be a and b.
The sum of the two is 19. Therefore:
[tex]a+b=19[/tex]
One number (let's use a) is 7 more than twice the other. Thus:
[tex]a=7+2b[/tex]
Solve for the system of equations. Substitute the second equation into the first:
[tex]a+b=19\\(7+2b)+b=19[/tex]
Subtract 7 from both sides:
[tex]2b+b=12[/tex]
Combine like terms:
[tex]3b=12[/tex]
Divide by 3:
[tex]b=4[/tex]
So, b is 4.
And since they add up to 19, this means that a is:
[tex]a+b=19\\a+4=19\\a=15[/tex]
So our numbers are 4 and 15
And we are done :)

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease. y=570(0.98)^x
Answer:
decay2% decreaseStep-by-step explanation:
The growth factor is the base of the exponent: 0.98. Its relation to the rate of change is ...
growth factor = 1 + rate of change
0.98 = 1 + (-0.02)
So, the rate of change is -0.02 = -2%. Since the rate of change is a 2% decrease, it represents decay.
A triangle has a base of 16 inches and a height of 18 inches. What is its area?

On a number line suppose point E has a coordinate of 1, and EG=11 What are the possible coordinates of G?
Answer:
- 10 and 12
Step-by-step explanation:
On a typical number line, we have basically two directions that we can move on. Either to the left where the numbers are negative, of to the right where the numbers are positive.
Given that point E has a coordinate of 1 on a number line, and we are told that the distance between E and another point on the number line is 11 (EG), the possible coordinates of point G are two (either we are moving to the right or to the left). Therefore, possible coordinates of G are:
1 - 11 = -10 (to the left)
1 + 11 = 12 (to the right)

An executive invests 29,000, some at 8% and the rest at 7% annual interest. If he receives an annual return of $2,230, how much is invested at each rate?
Answer:
Amount invested in A (8%) = $20,000
Amount invested in B (7%) = $9,000
Step-by-step explanation:
Given:
Total amount invested = $29,000
Interest rate A = 8% = 0.08
Interest rate B = 7% = 0.07
Annual return = $2,230
Find:
Amount invested in each
Computation:
Assume;
Amount invested in A = x
Amount invested in B = 29,000 - x
So,
Interest receive from A = x × 0.08
Interest receive from A = 0.08 x
Interest receive from B = (29000 - x) × 0.07
Interest receive from B = 2,030 - 0.07 x
Annual return = Interest receive from A + Interest receive from B
2,230 = 0.08 x + 2,030 - 0.07 x
x = 20,000
Amount invested in A = $20,000
Amount invested in B = 29,000 - $20,000
Amount invested in B = $9,000
Suppose that on each play of a game, a gambler either wins 1 with probability p or loses 1 with probability 1–p (or q). The gambler keeps betting until she or he is either up a total of n or down a total of m. What is the probability the gambler will quit an overall winner? You must consider both cases when p = 0.5 and when p ≠ 0.5
Answer:
Step-by-step explanation:
From the given information,
Considering both cases when p = 0.5 and when p ≠ 0.5
the probability that the gambler will quit an overall winner is:
[tex]P = \dfrac{1 - (\dfrac{1-p}{p} )^K}{1- (\dfrac{1-p}{p})^N } \ \ \ is \ p \neq 0.5 \ and\ K/N = \dfrac{1}{2}[/tex]
where ;
N.k = n and k = m
Hence, the probability changes to:
[tex]P = \dfrac{1 -(\dfrac{1-p}{p})^m}{1 -(\dfrac{1-p}{p})^{m+n}}[/tex] is p ≠ 0.5 and k/N = [tex]\dfrac{m}{m+n}[/tex] is P = 0.5

in 2016 the average Raleigh driver spent 18 hours in traffic jams, which accounted for 6% of their total driving time. How many hours did the average Raleigh driver spend behind the wheel in 2016
Answer: 300 hrs
The time spent behind the wheel by the average Raleigh driver in 2016 is 300 hrs
Step-by-step explanation:
Given that;
Raleigh driver spent 18 hours in traffic jams
And it accounts for 6% of their total driving time
Now
let total driving time be = x hrs
so
6% of total driving time = 18 hrs
6/100 × x = 18hrs
6x = 1800 hrs
x = 1800/6
x = 300 hrs
∴ The time spent behind the wheel by the average Raleigh driver in 2016 is 300 hrs
