Answer:
Step-by-step explanation:
1.)12.
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator.
Thus, the answer to 4 divided by 1/3 in fraction form is:
[tex]\frac{12}{1}[/tex]
To make the answer to 4 divided by 1/3 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
12
The answer is rounded to the nearest two decimal points if necessary.
[tex]\frac{12}{1}[/tex] is an improper fraction and should be written as 12.
2.) 9
The current population of Rochester is 211,000 and is decreasing at a rate of 4.1% every ten years. Which function can be used to find the population 30 years from now?
Answer:
211,000(0.97)t
Step-by-step explanation:
Firstly; Write the exponential decay function for this situation.
y = a(1 – r)t Write the formula.
= 211,000(1 – 0.041)t Substitute 1700 for a and 0.03 for r.
= 211,000(0.97)t Simplify.
Next; Find the population in function.
y = 1700 Substitute 12 for t.
≈ 1180 Use a calculator and round to the nearest whole number.
The population in 30 years function will be approximately 211,000(0.97)t.
The point P(6, –1) is translated according to the rule (x, y) → (x – 5, y – 2). What are the coordinates of P'? P'(1, 2) P'(1, 1) P'(1, –3) P'(4, 4)
Answer:
(1, -3)
Step-by-step explanation:
If the point P(6, –1) is translated according to the rule (x, y) → (x – 5, y – 2).
To get the coordinate of P', we will replace x as 6 and y as -1 in the translation given as shown
Coordinate of P' = (6 -5, -1, -2)
Coordinate of P' = (1, -3)
hence the coordinate of P' is (1, -3)
Answer:
p'(1 -3)

Answer:
7,13,37,55,103
Step-by-step explanation:
y = 5 + 2x^2
if x =1
y = 5 + 2(1)^2
1^2 = 1
2 x 1 = 2
y=5 + 2 or y = 7
you substatute each one in for x to solve for y

Tamekia and Marsha mow lawns during the summer to earn money. Tamekia determined that she can earn between $6.00 and $6.25 per hour. Marsha estimates that she earns between $7.50 and $8.00 per hour. About how much more money will Marsha earn than Tamekia if they each work 22 hours?
Answer:
$33 - $38.50
Step-by-step explanation:
Tamekia $6.00 - $6.25
y = mx
y = (22)(6) = 132
y = (22)(6.25) = 137.50
$132 - $137.50
Marsha $7.50 - $8.00
y = (22)(7.5) = 165
y = (22)(8) = 176
$165 - $176

If the length of the longer leg in a 30°-60°-90° triangle is 5V3, what is the length of the shorter leg?
A. 3
B. 5
C. 5v2
D. 10
Answer:
B. 5
Step-by-step explanation:
Let x = length of shorter leg
longer leg = [tex]\sqrt{3}[/tex] times the shorter leg
5[tex]\sqrt{3}[/tex] = x[tex]\sqrt{3}[/tex]
x = 5

Uno se pierde, el otro se recicla.
Explicación:
El movimiento de nutrientes difiere del flujo de energía en un ecosistema porque los nutrientes se pueden reciclar mientras que, por otro lado, la energía se pierde en el ecosistema. Tanto los nutrientes como la energía fluyen en la misma dirección y toda la energía del ecosistema proviene del sol, que es la principal fuente de energía. Entonces podemos decir que la energía perdida y los nutrientes se reciclan en el ecosistema.

Answer:
x=70
Step-by-step explanation:
it's 70 because 50 and 20 is proportional to x
Answer:
70
Step-by-step explanation:
The angles <FEB and <AEG are vertical angles. This means they have the same measurement. To find <FEB add the two angles <FED and <DEB together. This equals 70; therefore, x must also be equal to 70 degrees.

Answer:
Value of x using quadratic formula (x = -4) and (x = -5)
Step-by-step explanation:
Given:
Equation
x² + 9x + 20 = 0
Find:
Value of x using quadratic formula
Computation:
Quadratic formula = [-b±√b²-4ac] / 2a
Given equation;
x² + 9x + 20 = 0
a = 1 , b = 9 , c = 20
By putting value
[-9±√9²-4(1)(20)] / 2(1)
[-9±√81-80] / 2
[-9±√1] / 2
(-9 + 1) / 2 , (-9 - 1) / 2
-8 / 2 , 10 / 2
-4 , - 5
