A city is growing at a rate of 8 percent per year. What multiplier is used to find
the new population each year?
Answer:
1.08
Step-by-step explanation:
This is because it grows upon itself so it starts with a multiplier of 1, but it is growing with .08 (8 percent) on itself so you add these two numbers together to get 1.08

whats the answer to
-7y=7x+21
Answer:
y = -x - 3
x = -y - 3
Step-by-step explanation:
If solving for y,
-7y = 7x + 21
-y = -x + 3 (dividing everything by 7)
y = -x - 3
If solving for x,
-7y = 7x + 21
-y = -x + 3
x = -y - 3

A sports drink bottle contains 16.9 fluid Ounces. Andre drank 80% of the
bottle. How many fluid Ounces did Andre drink?
Answer:
13.52 fluid ounces should be the right answer! :)
Step-by-step explanation:
Andre drank from the bottle 13.52 fluid ounces if he drank 80% of bottle.
What is Percentage?Percentage is defined as the parts of a number in a whole of 100. This is denoted by the symbol '%'.
In other words, percentage can be defined as the ratio expressed as a fraction of 100.
Any number can be expressed as a percentage of another number by dividing the number with the whole of other number and then multiplying with 100.
Given that, fluid contained in a sports bottle = 16.9 fluid ounces.
Andre drank 80% of the fluid contained in the bottle.
80% of the bottle = 80% × 16.9
= (80 / 100) × 16.9
= 0.8 × 16.9
= 13.52
So this is the total fluid ounces Andre drink.
Hence Andre drank 13.52 fluid ounces from the bottle.

3. The ratio of the width to the length of a rectangle is 4:5. If the area of the rectangle is 500 square centimeters, what is the length of the rectangle?
5 centimeters
9 centimeters
20 centimeters
25 centimeters
Answer:
25 centimetersStep-by-step explanation:
Ratio 4:5 means:
width: W = 4x
length: L = 5x
Area of rectangle: A = W×L
Therefore:
500 = 4x×5x
500 = 20x²
50 = 2x²
x² = 25
x = 5
W = 4×5 = 20 cm
L = 5×5 = 25 cm
What is the slope of line a?
========================================================
Explanation:
Start at the point (0,1). This is the y intercept, which is where the graph crosses the y axis.
Then move down 1 and over to the right 4 spaces. We arrive at (4,0) which is the x intercept.
The process of "down 1, over to the right 4" can be thought of like this
rise/run = -1/4
rise = -1
run = 4
A rise of -1 indicates we go down 1 unit
The run of 4 means we move to the right 4 units
So that's why slope = rise/run = -1/4
-------------------------------------------------------
Here's another approach using the slope formula:
m = (y2-y1)/(x2-x1)
m = (0-1)/(4-0)
m = -1/4
I used the two points (0,1) and (4,0) as (x1,y1) and (x2,y2) respectively. This formula basically says "subtract the y coordinates, subtract the x coordinates in the same order, then divide the differences y over x".
-------------------------------------------------------
Side note: The line moving downhill, as we read from left to right, indicates a negative slope.

Answer: Alright So, A bag is filled with green and blue marbles. There are 48 marbles in the bag. If there are 38 more green marbles than blue marbles, find the number of green marbles and the number of blue marbles in the bag.
------
Equations:
g + b = 48 marbles
g = b + 38
------
Substitute for "g" and solve for "b"::
b+38 + b = 48
2b = 10
b = 5 (# of blue marbles)
g = b+38 = 43 (# of green marbles)

En la tienda de mascotas "Animalo-T", se desea elevar un elefante de 2,900 kg utilizando una elevadora hidráulica de plato grande circular de 75 cm de radio y plato pequeño circular de 13 cm de radio. ¿Calcula cuánta fuerza hay que hacer en el émbolo pequeño para elevar al paquidermo?
Answer:
Se requiere una fuerza de 854.473 newtons sobre el émbolo pequeño.
Step-by-step explanation:
Por el Principio de Pascal se conoce que el esfuerzo experimentado por el elefante es igual a la presión ejercida por el plato pequeño. Es decir:
[tex]\frac{F_{1}}{A_{1}} = \frac{F_{2}}{A_{2}}[/tex] (1)
Donde:
[tex]F_{1}[/tex] - Fuerza experimentada por el elefante, medida en newtons.
[tex]F_{2}[/tex] - Fuerza aplicada sobre el plato pequeño, medida en newtons.
[tex]A_{1}[/tex] - Área del plato grande, medida en metros cuadrados.
[tex]A_{2}[/tex] - Área del plato pequeño, medida en metros cuadrados.
La fuerza aplicada sobre el plato pequeño es:
[tex]F_{2} = \left(\frac{A_{2}}{A_{1}} \right)\cdot F_{1}[/tex]
La fuerza experimentada por el elefante es su propio peso. Por otra parte, el área del plato es directamente proporcional al cuadrado de su diámetro. Es decir:
[tex]F_{2} = \left(\frac{D_{2}}{D_{1}} \right)^{2}\cdot m\cdot g[/tex] (2)
Donde:
[tex]D_{1}[/tex] - Diámetro del plato grande, medido en centímetros.
[tex]D_{2}[/tex] - Diámetro del plato pequeño, medido en centímetros.
[tex]m[/tex] - Masa del elefante, medida en kilogramos.
[tex]g[/tex] - Aceleración gravitacional, medida en metros por segundo cuadrado.
Si sabemos que [tex]D_{1} = 0.75\,m[/tex], [tex]D_{2} = 0.13\,m[/tex], [tex]m = 2900\,kg[/tex] y [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], entonces la fuerza a aplicar al émbolo pequeño es:
[tex]F_{2} = \left(\frac{0.13\,m}{0.75\,m} \right)^{2}\cdot (2900\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)[/tex]
[tex]F_{2} = 854.473\,N[/tex]
Se requiere una fuerza de 854.473 newtons sobre el émbolo pequeño.
