Answer:
Given:
Length = 3x m
Breadth = 2x m
Perimeter = 250m
Need to find:
The value of x=?
Solution:
We know,
Perimeter of rectangle = 2×(length + breadth)
Substitute the values!
→ 250m = 2 ×( 3x + 2x) m
→ 250 = 2 × 5x
→ 10x = 250
→ x = 25

The population of bacteria in an
experiment is increasing by 90% each
day. If there were 100 bacteria at the
beginning of the experiment, predict the
number of bacteria in 5 days.
First, complete the equation:
Future Amount = 100(1 +0.90) [?]
Answer:
5
Step-by-step explanation:
5 makes sense since the period of time this takes place is 5 days. therefore [?] should be 5
The number of bacterias increases in 5 days will be 1790.
What will be the bacterial growth?
The bacteria number is increasing day by day the function which shows the bacterial growth is given as Future amount = 100(1+0.9)⁴'⁵.
Now the bacterial growth will be:-
Future amount = 100 ( 1 + 0.9 )⁴'⁵.
Future amount = 100 ( 1.9 ) ⁴'⁵.
Future amount = 1790
Therefore the number of bacterias increases in 5 days will be 1790.

Answer:

Explanation:
Recall that the formula for compound interest is:
A = P ( 1 + r/ n ) n ( t )
−−−−−−−−−−−−−−−−−−−−−−
where:
A = future value
P = principal (starting) amount
r = annual interest rate, expressed as a decimal
n = number of times the interest is compounded in a year
t = number of years compound interest occurs for
1 . Start by substituting your known values into the formula. Note that the annual interest rate is − 0.15 since the car depreciates (becomes lower in value) each year.
A = 25000 ( 1 + − 0.15 1 ) 1 ( 5 )
2 . Solve for A .
A = 25000 ( 0.85 ) )5
A = 11092.63

(4x+1)+(5x-4)+E=180, find E
Answer:
(4x + 1) + (5x + 4) + E = 180.
Simplify: Combine the x values
4x + 5x = 9x.
Now add 4 + 1 = 5.
So far we have; 9x + 5 + E = 180.
180 - 5 = 175.
9x = 175
175/9 = 19.4 repeated. X = 19.4 repeated.
Substitute in the value we have so far.
(4 x 19.4 repeated + 1) + (5 X 19.4 repeated + 4) = 180
So, E must be 0 for this equation to work.

2 Nine identical circles are cut from a square sheet of paper whose sides are
36 centimeters long. If the circles are as large as possible, what is the area
of the paper that is left after all the circles are cut out? Use 3.14 as an
approximation for π.
Answer:
278.64cm²
Step-by-step explanation:
Area of the sheet left out = Area of the square - Area of the 9 circles
Area of the square = L^2
L is the side length of the square
A = 36^2
Area of the square = 1296cm^2
Diameter of a circle = 38/3 = 12cm
Area of a circle = πr²
r is the radius = 12/2 = 6cm
Area of a circle = 3.14(6)²
Area of a circle = 3.14 * 36
Area of a circle = 113.04cm²
Area of 9 circles = 9 * 113.04
Area of 9 circles = 1,017.36cm²
Area of the left over = 1296 - 1,017.36
Area of the left over = 278.64cm²

Plz hurry D:
Answer:
I beleive Kasey can make 36 servings of gelatin. If you want you can check your answer by using the steps I provided.
Step-by-step explanation:
1. First we need to see how many times 1 1/3 can go into 8, or (how many gelatin molds can be filled. So, we will divide 8 divided by 1 1/3 to get (6.)
2. So, since we can fill 6 gelatin molds and each mold makes six servings, we will multiply 6 times 6 to get our answer 36.

34 yards of carpet weighs 51 pounds.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, 20 yards of carpet weighs 30 pounds.
Here, 1 yard of carpet weighs = 30/20
= 1.5 pounds
34 yards of carpet weighs
= 34×1.5

Flor tiene una papelería y vende los lápices en $12 y los bolígrafos en $20. ¿Qué expresión algebraica permite saber cuánto debe cobrar Flor por 10 bolsas que contengan x cantidad de lápices y "y" cantidad de bolígrafos?
Answer:
c=120x+200y
Step-by-step explanation:
La expresión algebraica debería indicar que el valor total que debe cobrar Flor es igual a 10 que representa el número de bolsas por el resultado de la suma del precio de cada item por la cantidad, lo que se puede expresar de la siguiente forma:
c=10(12x+20y)
c=120x+200y
De acuerdo a esto, la expresión algebraica que permite saber cuánto debe cobrar Flor por 10 bolsas que contengan x cantidad de lápices y "y" cantidad de bolígrafos es c=120x+200y.
