Answer:
The powers of 10 are things of the form:
10^n.
Where we assume that n is an integer number.
if is equal or larger than 0, then:
We add n zeros at the right of the 1.
so let's write some examples.
10^0 = 1 (we do not add any zero)
10^1 = 10 (we add one zero)
10^2 = 100 (we add two zeros)
...
Now, remember that x^-y = 1/x^y, then:
If n is smaller than zero, then we add n zeros at the left of the 1.
10^-1 = 1/10 = 0.1 (one zero at the left)
10^-2 = 1/100 = 0.01 (two zeros at the left).
Those relations will be useful to always know the exact dimensions of the powers of zero.
Now, we can give a more complete description knowing that:
x^a*x^b = x^(a + b)
Then if we have:
10^3*10^4 = 100*1,000 (and this may be hard to do)
But we can use the above relation:
10^3*10^4 = 10^(3 + 4) = 10^7
Then we know that we must add 7 zeros at the right of the 1.
And this will work for any integer powers of 10.
7/8 square foot in 1/4 hour
Answer:
2 1/2
Step-by-step explanation:
The unit rate for the given parameters is 3 1/2 square feet /hour.
Given that, 7/8 square feet in 1/4 hour.
We need to find the unit rate.
How to find unit rate?In a unit rate, the denominator is always 1. So, to find the unit rate, divide the denominator with the numerator in a way that the denominator becomes 1.
Now, unit rate = 7/8 ÷ 1/4
=7/8 × 4 =7/2
=3 1/2 square feet /hour
Therefore, the unit rate for the given parameters is 3 1/2 square feet /hour.

The curved surface area of a right circular cylinder of height14 cm is 88 cm2. Find the diameter of the base of the cylinder.
Answer:
4
Step-by-step explanation:
The formulae for Curved surface
area = πrh
Area = 88cm2
height = 14cm
radius = ?
Let π be 22/7
88 = 22/7 x r x 14
cross multiply
88 x 7 = 22 x 14 x r
616 = 308r
Divide both sides by 308
r = 2
Diameter = Radius x 2
so our radius is 2, 2 x 2 = 4

Your family drives across Kansas on Interstate 70. A sign reads, “Wichita 90 mi, Topeka 110 mi”. What is the possible range of distances between the two cities given that the cities are not collinear?
Answer:
20 miles < The distance between the cities < 200 miles
Step-by-step explanation:
The given information on the sign = "Wichita 90 mi, Topeka 10 mi"
Given that the two cites are not colinear, we have;
The number of points specified in the figure = 3 points
The specified points are;
1) The location of the family
2) The location of Wichita, relative to the family's location, = 90 mi
3) The location of Topeka, relative to the family's location, = 110 mi
Therefore, given that the three points are not colinear, they form the vertices of a triangle
The legs of the triangle are 90 mi and 110 mi
The maximum distance between Wichita and Topeka is therefore = 90 + 110 = 200 miles
The minimum distance distance from Wichita to Topeka = 110 - 90 = 20 miles
Therefore, the possible range of distances between the two cities is 20 miles to 200 miles.
Which gives;
20 miles < The distance between the cities < 200 miles.
A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 6 1/4 °F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation. Complete the steps below to solve the problem.
Step-by-step explanation:
At the elevation 617.5 feet below the sea level temperature of the water was °F
Step-by-step explanation:
At 502.5 feet below the sea level temperature of the water is °F
When submarine dives down 115 feet deeper, water temperature drops by °F
Elevation after the submarine dove = -502.5 - 115 = -617.5 feet
This negative sign represents the elevation below the sea level.
And the temperature will be =

4(2x - 5) -6( ) = 6+9) + (2x - 5)
Answer: x=6
Step-by-step explanation:
Step 1: Remove parentheses.
4(2x-5)-6=6+9+2x-54(2x−5)−6=6+9+2x−5
Step 2: Simplify 6+9+2x-56+9+2x−5 to 2x+102x+10.
4(2x-5)-6=2x+104(2x−5)−6=2x+10
Step 3: Expand.
8x-20-6=2x+108x−20−6=2x+10
Step 4: Simplify 8x-20-68x−20−6 to 8x-268x−26.
8x-26=2x+108x−26=2x+10
Step 5: Add 26 to both sides.
8x=2x+10+268x=2x+10+26
Step 6: Simplify 2x+10+262x+10+26 to 2x+362x+36.
8x=2x+368x=2x+36
Step 7: Subtract 2x2x from both sides.
8x-2x=368x−2x=36
Step 8: Simplify 8x-2x8x−2x to 6x.
6x=36
Step 9: Divide both sides by 6.
x= 36/6 as a fraction
Step 10: Simplify \frac{36}{6} to 6.
x= 6x
[tex] \bold{4(2x - 5) -6 = 6+9) + (2x - 5)}[/tex]
[tex] \bold{4(2x−5)−6=6+9+2x−5}[/tex]
[tex] \bold{4(2x−5)−6=2x+10}[/tex]

[tex] \bold{6x=36}[/tex]
[tex] \bold{x = \cfrac{36}{6}} [/tex]
[tex] \bold{x = 6}[/tex]
Note: The Parentheses must be eliminated to then use the law of signs, then we must expand the numbers, then simplify (that is, subtract) Now in the next step is to Add 26 on both sides then we must subtract and then add until we get the result of 6, so that ultimately we can take out a fraction and give us the correct answer, which is [tex]\bold{x=6}[/tex]

Consider the expression –4b + 8c + 12 – 8b – 2c + 6. Part A Simplify the expression. b + c + Part B Factor the simplified expression using the GCF. 2(–2b + c + 3) 3(–2b + c + 3) 4(–2b + c + 3) 6(–2b + c + 3) Part C What is the value of the expression when b = 2 and c = –3?
Answer:
Step-by-step explanation:
Given the expression
-4b + 8c + 12 – 8b – 2c + 6.
To simplify, first collect the like terms
= (-4b-8b)+(8c-2c)+(12+6)
= -12b+6c+18
Factor out the GCF
The GCF is 6
On factoring out;
= 6(-2b+c+3)
If b = 2 and c = -3 the expression becomes:
= 6(-2(2)+(-3)+3)
= 6(-4-3+3)
= 6(-4+0)
= 6(-4)
= -24
Hence the value of the expression when b = 2 and c = -3 is -24

-0.4
Step-by-step explanation:
You need to combine like terms, whatever that means. So you would add 2x and 3x to get 5x, and then 4+(-2), which would get you to 5x+2=0. Next, you subtract 2 from both sides, so you have 5x=(-2), and then you have to divide both sides by 5.

Answer: The first graph is the answer.
Step-by-step explanation: If your parents house is 100 hours away, and you're driving at 50 mph, then it would take 2 hours to get to you're parents house (100 ÷ 2 = 50). Then you stay at your parents house for 5 hours (2 + 5 = 7), the graph stays the same place on the y axis for 5 hours. Afterwards you drive home, same distance as when you drove to your parents (2), but you're going back so it's going down. This makes graph 1 the answer.
