Answer:
7.7 × [tex]10^{6}[/tex]
Step-by-step explanation:
Start off with finding the digits in this case it would be 7,700,000
Now insert a decimal so that it is a number under 10.
That would be 7.7
to figure out what the exponent would be you have to count how many "jumps" the decimal takes to get back to the original number.
It would take 6 "jumps" to end up back to 7,700,000
Now that we have that information we can make the scientific notation
1) Take the number (7.7)
2) Multiply the number by 10 with the exponent of "jumps"
Thus,
7.7 × [tex]10^{6}[/tex]

The police are searching for a bank that has been on the run for two hours. Based on his running speed, the police believe he could be anywhere within an 8.5 mile radius of the bank. Find the area and circumference of the region in which they must search for the suspect. Round to the nearest whole unit.
Answer:
π is equivalent to 3.14
Circumfrance = 53
area = 227
Step-by-step explanation:
π is equal to 3.14
Circumfrance = 8.5*2*π
So 8.5 * 2 is 17 times π is 53.38
round to nearest whole number is 53
area is π * radius squared so
8.5 * 8.5 =72.25
* π is 226.865
round to the nearest whole number is 227

2p+3q=-7
3p+5q=-12
What is the solution in an ordered pair?
Answer:
(p, q ) = (1, - 3 )
Step-by-step explanation:
2p + 3q = - 7 → (1)
3p + 5q = - 12 → (2)
Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate p
6p + 9q = - 21 → (3)
- 6p - 10q = 24 → (4)
Add (3) and (4) term by term to eliminate p
0 - q = 3
-q = 3 ( multiply both sides by - 1 )
q = - 3
Substitute q = - 3 into either of the 2 equations and solve for p
Substituting into (1)
2p + 3(- 3) = - 7
2p - 9 = - 7 ( add 9 to both sides )
2p = 2 ( divide both sides by 2 )
p = 1
Audrey & Jack begin a candlelight
dinner at 5pm with a 9-inch candle. At
8pm, their candle is only 3 inches.
What is the average rate of change of
the height of the candle per hour?
Answer:
-2 inches per hour
Step-by-step explanation:
Finding the average rate of change is just like finding the slope. So, take the y values (height) and subtract them and divide that by the difference in the x values (time).
( 3 - 9 ) / ( 8 - 5 )
= -6 / 3
= -2 inches per hour

between the two locations?
Plz help me quick
Answer 1 3/5 meter below sea level
In this case, a diver goes into two different location expressed with "meters below sea level" unit. To know the distance between the two location, then you need to subtract it.
Step-by-step explanation:
Distance = 2nd location - 1st location
Distance = 8 1/5 meter below sea level - 6 3/5 meter below sea level= 1 3/5 meter below sea level

Answer:
1. 5 + r/14
2. 3x -4 = 23
Answer:
1. 5 + r/14
1. 3x - 4 = 23
Step-by-step explanation:
1. Remember, the quotient is obtained by dividing one quantity by another. In the sentence it is stated that "the quotient of r and 14" which means: r divided by 14.
The sentence models 5 + r/14
2. We are to subtract 4 from the product of 3 and x. So part of the equation looks like: "3x-4". Since it is stated that 23 is the total sum, then the answer is: 3x - 4 = 23

What are the solutions to the equation |X – 3|= 14?
x= 11 only
Ox= -11 and x = 17
x= 17 only
x= -11 and x=11
Answer:
{-11,17}
Step-by-step explanation:
|X – 3|= 14
There are two solutions to an absolute value, one positive and one negative
x-3 = 14 and x-3 = -14
Add 3 to all sides
x-3+3 =14+3 x-3+3 = -14+3
x = 17 x = -11
x = {-11,17}

Can someone please explain how to answer these
Answer:
1) x = 13 (because other angle of the triangle is 45°.Then the foots faced to equal angles are equal)
Then we can calculate y by pythagoras law
[tex] {y}^{2} = {x}^{2} + {13}^{2} \\ {y}^{2} = {13}^{2} + {13}^{2} \\ y = \sqrt{2 \times 169} \\ y = 13 \sqrt{2} [/tex]

Wynter likes to take the long way to school each morning. He walks 4 blocks south and then 4 blocks west to arrive at the school. Today he is running late and decides go directly to school to save time. (Assume there is nothing obstructing his path.) If one block is 320 feet, how many feet will he travel if he goes directly to school? Round to the nearest tenth of a foot.
Distance travel by Drew = 1,315.21 feet (Approx)
What is distance?Distance is a measure of how far apart two objects or locations are using numbers. Distance can refer to a physical length in physics or to an estimate based on other factors in common usage. Sometimes, the symbol |AB| is used to represent the distance between two points.
Given:
Total block in north = 3
Total block in west = 3
1 block = 310 feet
Find:
Distance travel by Drew
Computation:
Total distance in north = 3 × 310 = 930 feet
Total distance in west = 3 × 310 = 930 feet
Distance travel by Drew = Total distance in
north? + Total distance in west?
Distance travel by Drew = v9302 + 9302
Distance travel by Drew:
= V864,900 + 864,900
Distance travel by Drew = V1,729,800
Distance travel by Drew = 1,315.21 feet (Approx)
