Answer:
26 m and 20 m
Step-by-step explanation:
Let the length of the room be l, the breadth be b and perimeter be P.
Given:
P/2 = 46 ml = b + 6 mSolutionSince P = 2(l + b), P/2 = l +b, we have following equations:
l + b = 46l = b + 6Substituting l in first equation:
b + 6 + b = 462b + 6 = 462b = 40b = 20 mThen the length is:
l = b + 6 = 20 + 6 = 26 mis the square root of 5 between 2 and 3
Answer: Yes, it’s 2.23607
The population of algae in an
experiment has been increasing by 40% each day. If there were 20 algae at the beginning of the experiment, predict the number of algae in 7 days.
First, complete the equation:
Future Amount = [?](1+[]0
The equation is y = 20(1.40)^x
where x is the number of days and y is the future amount after x days go by
The 1.40 is from the fact that 1+r = 1+0.40 = 1.40, where r is the decimal form of 40%, so r = 0.40
-----------------------------
Plug in x = 7 to get
y = 20(1.40)^x
y = 20(1.40)^7
y = 210.827008
y = 211
We round to the nearest whole number since it doesn't make much sense to have a fractional portion of an algae. After 7 days, there are about 211 algae.
In a certain county, the number of charter schools is 6 less than twice the number of alternative schools. We know that there are 52 charter schools in the county. How many alternative schools are in the county?
Answer:
29
Step-by-step explanation:
Answer:
29
Step-by-step explanation:
So, 52 charter schools and the number is 6 less than the alternative schools doubled. In order to find the number of alternative schools, we need to reverse the equation. 52+6=58. That means 58 is twice the amount of alternative schools. 58/2 equals 29, therefore the answer is 29

Step-by-step explanation:
[tex] \sf{5 \div \frac{2}{5} }[/tex]
When any number of fraction is divided by a fraction , we multiply the dividend by reciprocal of the divisor.
We can obtain the reciprocal of any fraction by interchanging the position of numerator and denominator.
⇒[tex] \sf{5 \times \frac{5}{2} }[/tex]
To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator.

what is the standard deviation for 54, 36, 30, 28, 27
Answer:
11.18
Step-by-step explanation:
Step 1: average : (54+36+30+28+27) / 5 = 35
Step 2: variance:
sum of the squares of (each number - average value) divided by (n-1)
[ (54-35)^2 + (36-35)^2 + (30-35)^2 + (28-35)^2 + (27-35)^2 ] / (5-1) = 125
Step 3: standard deviation = √(variance) = √125 = 5√5 (about 11.18)

Step-by-step explanation:
divide 10kg in the ratio of 13 : 7
Answer:
6.5 : 3.5
Step-by-step explanation:
So to do this sum;
First, add both 13 and 7 which is 20
Then, 13/20 *10 = 6.5
and 7/20 *10 = 3.5
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3). Equal quotients correspond to equal ratios.

Step-by-step explanation:
The average price of gasoline in Paris, France, is 1.91 euros per liter. If there are 3.785 liters in one gallon, and the exchange rate is 1.203 euros for one dollar, what is the price of gas in dollars per gallon for gasoline in Paris?
The price of gasoline in Paris is $.61/gallon
The price of gasoline in Paris is $2.38/gallon
The price of gasoline in Paris is $6.00/gallon
Answer:
The price of gasoline in Paris is $6.00/gallon
Step-by-step explanation:
We are asked to find the price of gas in dollars per gallon for gasoline in Paris.
Step 1
We are told in the question that: the average price of gasoline in Paris, France, is 1.91 euros per liter.
Also we are told that, the exchange rate is 1.203 euros for one dollar
We convert the Euros to dollars
If, 1.203 euros = 1 dollar
1.91 euros = x dollars
We Cross Multiply
1.203 euros × x dollars = 1.91 euros × 1 dollar
x dollars = 1.91 euros × 1 dollar/ 1.203 euros
x dollars = 1.5876974231 dollars
Therefore, 1.203 euros = Approximately 1.59 dollars.
Hence, the price of gasoline in Paris, France is 1.59 dollars per liter.
Step 2
We convert the from liter to gallon
In the question, we are told that:
If there are 3.785 liters in one gallon
Therefore, if
1 liter of gasoline = 1.59 dollars
3.785 liters of gasoline =
Cross Multiply
= 3.785 liters × 1.59
= 6.01815 dollars.
Approximately to the nearest whole number = 6.00 dollars.
Since 3.785 liters of gasoline = 1 gallon of gasoline, therefore, the price of gas in dollars per gallon for gasoline in Paris is $6.00/gallon

cual es el resultado de (7.006×10⁴¹)×(5.09×10²²)
Answer:
El resultado de (7.006×10⁴¹)×(5.09×10²²)=3.566054*10⁶⁴
Step-by-step explanation:
La notación científica es una manera rápida de representar un número utilizando potencias de base diez.
Los números se escriben como:
a*10ⁿ
donde:
a es un número real mayor o igual que 1 y menor que 10.n es un número entero, que recibe el nombre de exponente u orden de magnitud. Representa el número de veces que se desplaza la coma. Siempre es un número entero, positivo si se desplaza a la izquierda, negativo si se desplaza a la derecha.Para realizar la multiplicación con notación científica, debes multiplicar las magnitudes afectadas por las potencias de 10 y, por separado, multiplicar las potencias de 10, recordando la propiedad:
Si dos bases son iguales (el mismo número o variable), y son los factores de una multiplicación, ambas bases quedan en una sola y sus exponentes son sumados: xᵃ*xᵇ= xᵃ⁺ᵇEn este caso:
(7.006×10⁴¹)×(5.09×10²²)=(7.006*5.09)*(10⁴¹*10²²)=35.66054*10⁴¹⁺²²= 35.66054*10⁶³
Siguiendo el formato a*10ⁿ, debes ajustar el valor de la base a de manera que sea un número real mayor que 1 y menor que 10. Entonces, se mueve la coma decimal hacia la izquierda tantos espacios hasta llegar a la derecha del primer dígito. Y se escribe la base 10, al cual el exponente se suma la cantidad de espacios que se mueve la coma, que es un número positivo porque la coma se desplaza a la izquierda.
Entonces 35.66054*10⁶³= 3.566054*10⁶⁴
El resultado de (7.006×10⁴¹)×(5.09×10²²)=3.566054*10⁶⁴

Taking the square root of a number is the *blank * Of squaring a number
Answer:
Opposite
Step-by-step explanation:
They are complete opposites:
When you take the square root of a number, you are taking the number to the 1/2 power. For example, the square root of 9 is 3.
When you square a number, you multiply it by itself. For example, 3 squared is 9.
So, these are opposites because when doing these operations to the same number, the products will be "opposites" of each other, like the examples above.

A: noncoplanar segments
B. parallel segments
C. congruent segments
D. perpendicular segments
first person to get it right will get brainliest
Answer:
Option C → Congruent segments
Step-by-step explanation:
The meaning of segment bisector is a segment which divides another segment into two equal parts.It is not necessary that the segement which is bisecting the another segment are perpendicular with one another.
So, when a segment is bisected the two segments are equal.
Equal means the two segments are congruent.

Select all the ways the rectangle could have been rotated to get from Frame 1 to Frame 2. 40 degrees clockwise 40 degrees counterclockwise 90 degrees clockwise 90 degrees counterclockwise 140 degrees clockwise 140 degrees counterclockwise Lesson 3
Answer:
40 degrees clockwise
140 degrees counterclockwise
Step-by-step explanation:
The rectangle is rotated in Figure B. The angle of rotation is 40 degrees. If we rotate a rectangle at an angle of 40 degrees clockwise then wit will be at the position as shown in figure B. The 90 degrees angle is perpendicular angle. Rectangle will not reach the desired position. If we rotate the rectangle at 140 degrees counterclockwise this will be the figure B representation. The rotation to 90 degree counterclockwise is either not suitable for the desired rectangle position.
