Answer:
1/5,764,801
Step-by-step explanation:
We have this as follows
All we have to do is use the laws of indices
We have it that;
a^-x = 1/a^x
a^x/a^y = a^(x-y)
Applying these laws;
7^-3/7^5
= 7^-3-5
= 7^-8
= 1/7^8
= 1/5,764,801

Answer:
(2x +1)/(4x^2) . . . . except x=0, -1
Step-by-step explanation:
Addition of fractions works in the usual way:
a/b +c/d = (ad +bc)/(bd)
Division of fractions works in the usual way:
(a/b)/(c/d) = (ad)/(bc)

-8a - 6b
The angle of elevation from a kicker's foot on the football field to the top of the goal post is 17 degrees. If he is standing 131 feet from the base of the goal post, how tall is the goal post?
Answer:
The goal post is 40.05 feet tall.
Step-by-step explanation:First, you need to decide whether to use sin, tan or cos.
You have the angle, the adjacent and need the opposite , so you need to find out which one has all three values in
Sin
Cos
Tan
So you need to use tan.
Tan = opposite / adjacent, so rearrange the formula to make opposite the subject:
[tex]Opp = Tan * adj
So simply plug these values in:
[tex]Opp =131 * tan(17) = 40.05
So the goal post is 40.05 feet tall
How many kilograms of 30% salt solution by mass and 40% salt solution by mass
should be mixed to form 200 kg of 37% salt solution by mass?
Answer:
60 kilograms of the 30% solution
140 kilograms of the 40% solution
Step-by-step explanation:
Let x = the no. of kilos containing 30% salt (solution 1)
and 200 - x = the no. of kilos containging 40% salt solution 2)
.30x = amount of salt in solution 1
.40(200 - x) = amount of salt in solution 2
.37(200) = amount of salt in the final mixture
salt in solution 1 + salt in solution 2 = salt in final mix.
.30x + .40(200 - x) = .37(200)
Let's multiply thru the equation by 100 to remove the decimal fractions
30x + 40(200 - x) = 37(200)
30x + 8000 - 40x = 7400
-10x = -600
x = 60 kilograms of the 30% solution
200 - 60 = 140 kilograms of the 40% solution
Mars has m moons. The number of moons of Pluto is one more than twice the number of moons of Mars. The number of moons of Neptune is one less than 3 times the number of moons of Pluto. Write and interpret a simplified expression that represents the number of moons of Neptune (I’m just asking to answer because I didn’t see any right ones when I was scrolling through them)
Answer:
neptune = 6m+2
Step-by-step explanation:
mars has 'm' moons
pluto has one more than twice that of mars, = 2m+1
neptune is one less than thrice of pluto
= 3(2m+1) -1
= 6m+3 -1
= 6m+2
A snow storm has blown across the united states. Currently, 30k square miles of land are affected. Each day, the land increases by 30% Equation: How much will the be hit by the snowstorm after 5 days?
Answer:
50,000 Square Miles.
Step-by-step explanation:
30% = 1/3
30,000/1 * 1/3 = 10,000
10,000 * 5 = 50,000

This is a similar triangle. Please find the missing length. (?)
Answer:
RQ = 10
Step-by-step explanation:
When two triangles are similar, the ratio of their corresponding sides are equal;
Thus, we have it that;
QP/RQ = BC/AB
12/RQ = 36/30
RQ = 12 * 30/36 = 10

Drawing a quick picture is helpful when adding decimals because it gives you a visual picture of what the answer is. Also, it gives you the opportunity to be sure that you got the correct answer because computations in adding may have some mistakes.
Step-by-step explanation:
What is the slope of the equation: y = - 5x -6
What is the y-intercept of the equation: y = 2x
Answer:
Step-by-step explanation:
y = mx +b
Here, m is slope and b is y-intercept
1) y = -5x - 6
Slope = -5
y-intercept = -6
2) y = 2x
Slope = 2
y-intercept = 0

Answer: 1.5 x 10^5
Step-by-step explanation:
The first step is to re-arrange the factors like this :
5 x 3 x 10^2 x 10^2
Since
5 x 3 = 15
and the index law
10^a x 10^b = 10^a + ^b
gives us
10^2 x 10^2 = 10^2 + ^2 = 10^4
then we can rewrite the product like this :
5 x 3 x 10^2 x 10^2 = 15 x 10^4
Finally, we need to convert this into scientific notation :
15 x 10^4 = 1.5 x 10^5
So the final answer is
1.5 x 10^5

A basket ball player attempts 15 baskets in a game . He makes 9 of the attemps what is the ratio
Answer:
9:15 or 3:5
Step-by-step explanation:
A ratio can compare a part of a whole to a whole.
In this case, our whole is the total number of shots attempted: 15.
The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.
Put these values in a ration.
part:whole
9:15
Notice that 9 and 15 can be simplified by dividing both numbers by 3.
3:5
This is your simplified ratio.
Hope this helps!

a flomming tile has the shape of a parallelogram whose base is 24cm and height is 10 cm how many tiles are required to cove the floor of area 1080m2
Answer:
4 1/2 tiles are needed to cover this area
Step-by-step explanation:
Mathematically, the area of a parallelogram is the product of the base and the height
We have this as;
24 * 10 = 240 cm^2
So the area of a tile is this
The number of tiles that will cover the given area will be;
1080/240 = 4.5 tiles
El Señor Carlos Villa quién Pide al Banco Azteca un crédito de $110000 sobre una tasa del 10% al año su cantidad a pagar será de
Responder:
121 000
Explicación paso a paso:
Dado que :
Monto del crédito = 110.000; este es el monto principal, P del préstamo
Tasa de interés = 10% = 10/100 = 0.1
Usando la relación para determinar el monto a pagar al final del año:
A = P (1 + rt)
A = monto final
A = 110 000 (1 + 0,1 * 1)
A = 11 000 (1 + 0,1)
A = 110 000 (1,1)
A = 121 000
La cantidad a pagar al final del año = 121.000
