Hey, Could any of you provide me a step by step explanation as to how you get to the answer?
(The step by step explanation is what I need most but please don't forget the answer)!

Answer:
Step-by-step explanation:
First start by finding the values of the numbers being multiplied together.
5^-2 = 25
This equals a positive 25 because when ever you multiply a negative by a negative it always equals a positive number. -5 x -5 = 25
[tex]\sqrt[3]{8}[/tex] = 2
This is asking what x what x what equals eight. Remembering that the square root of 4 is 2. We can determine that since 4 x 2 = 8 the cube root of 8 is 2.
2 x 2 x 2 = 8 and 8 divided by 2 divided by 2 = 2
So now solve the equation we have now. 25 x 2 =?
25 x 2 = 50
And 50 is our answer.

Answers
Answer:
x= 14/9 = 1 5/9
Step-by-step explanation:
Use the distributive property to multiply 2 by 5x−3.
2(5x−3)−4=x+4
Subtract 4 from −6 to get −10.
10x−6−4=x+4
Subtract x from both sides
10x−10=x+4
Combine 10x and −x to get 9x.
10x−10−x=4
Add 10 to both sides.
9x−10=4
Divide both sides by 9.
x= 14/9
Please mark brainliest.
2. do -6-4 --> 10x-10=x+4
3. add 10 on both sides --> 10x=x+4+10
4. subtract x on both sides and simplify equation --> 9x=14
5. divide both sides by 9 --> x=14/9

people did Iceland's population increase from 1990 to 2014?
A 330,825
B 132,330
C 125,312
D 80,200
Answers
Given:
The population density of Iceland, in people per square kilometer of land area, increased from 2.5 in 1990 to 3.3 in 2014.
Land area of Iceland = 100,250 square kilometers.
To find:
The Iceland's population increase from 1990 to 2014.
Solution:
Land area of Iceland is constant, i.e., 100,250 square kilometers.
The population density of Iceland, in people per square kilometer of land area in 1990 is 2.5. So, the population in 1990 is
[tex]2.5\times 100,250=250,625[/tex]
population density of Iceland, in people per square kilometer of land area in 2014 is 3.3. So, the population in 2014 is
[tex]3.3\times 100,250=330,825[/tex]
The Iceland's population increase from 1990 to 2014 is
[tex]330,825-250,625=80,200[/tex]
Therefore, the correct option is D.

Your mother gave you $13.32 with which to buy a present. This covered 3/5 of the cost. How much did the present cost?
A. Find the answer.
B. Write a formula for the problem.
Answers
Answer:
a. $22.2
b= 13.32/x=3/5
Step-by-step explanation:
13.32/x=3/5
13.32×5=66.6
66.6/3=22.2
x(present cost)=$22.2
Answer:
22.20$
3/5 * cost = 13.32
Step-by-step explanation:
3/5 * cost (total price) = 13.32 (we know that 3/5 of the price is 13.32)
to solve
5/3 to cancel out 3/5 and isolate the cost
5/3 * 13.32 = 22.20
A rocket ship travels at 2.0×104 miles per hour. If a satellite is 2.5×105 miles from Earth, how long will it take the rocket to make the trip from Earth to the satellite? (Hint: Divide the distance to the satellite by the speed.) Write your answer in scientific notation.
Answers
Answer: Time taken =1.25 x 10^1 hours 0r 4.5 x 10^4s
Step-by-step explanation:
Step 1
how long will it take the rocket to make the trip from Earth to the satellite = Time taken for the rocket to make the trip from Earth to the satellite
Speed = Distance / Time ,
Time = Distance / speed
Step 2-- solving
Time = Distance / speed
Time=2.5×10^5 miles/2.0×10^4 miles per hour
=12.5 hours = 1.25 x 10^1 hours
or 1.25 x 10^1 hours x 3600 = 45,000 seconds = 4.5 x 10^4s

Step-by-step explanation:
An emperor penguin travels a distance of 70 miles each year back to the place of its birth. If that same penguin moves at a speed of 2.4 miles per hour, the function d = 70 – 2.4t represents its distance d from its birthplace t hours after it has started its journey home. Find the zero of this function.
Answers
Answer:
29.17 hours
Step-by-step explanation:
to find the zero of the function, set d to equal zero, so
0 = 70 - 2.4t
-70 = -2.4t
-70/-2.4 = t
29.17 = t
A producer received rupees 10000 when the price of a commodity was rupees 100 per unit. The receipts increased to rupees 15000 when price increased by rupees 20.Calculate the elasticity of supply?
Answers
Answer:
Price Elasticity of Supply = 1.25
Step-by-step explanation:
Price Quantity Total Revenue ( P x Q)
100 10000/100 = 100 10000
120 15000/120 = 125 15000
Price Elasticity of supply is change in quantity supplied, due to change in price. Formula : (dQ / dP) x (P / Q)
(125 - 100) / (120 - 100) x (100/100)
= 25/20 = 1.25

Answer:
3x -4y = 12
Step-by-step explanation:
There are a number of different forms of the equation of a line. A few are ...
y = mx + b . . . . slope-intercept form
y -k = m(x -h) . . . . point-slope form
x/a +y/b = 1 . . . . intercept form
ax +by +c = 0 . . . . general form
ax +by = c . . . . standard form
In "standard form", the coefficients a, b, c are mutually prime integers (have no common factors) and the leading coefficient (usually, 'a') is positive.
__
Given this graph, there are several ways to get to a standard form equation. Perhaps the quickest is to start with intercept form. We can see from the graph that the x-intercept is 4 and the y-intercept is -3. So, we can write the equation of the line in intercept form as ...
x/4 +y/(-3) = 1
Multiplying this by 12 clears the fractions and gives us standard form:
3x -4y = 12

At a little-known vacation spot, taxi fares are a bargain. A 18-mile taxi ride takes 21 minutes and costs $12.60. You want to find the cost of a 39- mile taxi ride. What unit price do you need?
Answers
Given :
A 18-mile taxi ride takes 21 minutes and costs $12.60.
To Find :
The cost of a 39- mile taxi ride. What unit price do you need.
Solution :
Unit price per mile :
[tex]p=\dfrac{12.60}{18}\\\\p = \$0.7\ /mile[/tex]
Cost of 39 mile taxi ride :
[tex]C = 39\times p\\\\C=39\times 0.7\\\\C=\$27.3[/tex]
Therefore, unit price is $27.3 and unit price is $0.7 / mile .
Hence, this is the required solution.
