Answer:
4000
Step-by-step explanation:
A photo album can hold 8000 photos
Meera puts 1000 photos in the album
Her sister puts 3000 photos
= 1000+3000
= 4000
The number of photos that can still be put in the album can be calculated as follows
= 8000-4000
= 4000
A rectangular pen for pigs that will enclose a total area of 169 square feet. What is the least amount of fencing that is needed?
Answer:
The answer is below
Step-by-step explanation:
Let x represent the length of the rectangular pen and y represent the width of the rectangular pen. Since the total area of the pen is 169 ft², hence:
Area = length * width
169 = xy
y = 169/x
Also the perimeter of the rectangular pen is:
Perimeter (P) = 2(length + width)
P = 2(x + y)
P = 2x + 2y
P = 2x + 2(169/x)
P = 2x + 338/x
The least amount of fencing is at dP/dx = 0, hence:
dP/dx = 2 - 338/x² = 0
338/x² = 2
2x² = 338
x² = 169
x = 13 feet
y = 169 / x = 169/13 = 13 feet
The least amount of fencing = P = 2(x + y) = 2(13 + 13) = 52 feet

There are 4 students in a small class. To make a team, the names of 3 of them will be drawn from a hat. How many different teams of 3 students are possible?
Answer:
Step-by-step explanation:
Order shouldn't make any difference.
3 C 4 = 4!/(3! 1!) = 4
Let's see if that is right.
1 2 3
1 2 4
1 3 4
2 3 4
Any other combination will produce a duplicate if order doesn't matter. For example
2 4 3 is the same thing as 2 3 4
please help me i have 65 questions i have to do
If KJ=4 and KM= 2, find ML
Answer:
6
Step-by-step explanation:
(whole secant) * (external part) = (tangent)^2
(KL) * (KM) = KJ^2
(KM+ ML) * KM = KJ^2
(2+ ML) * 2 = 4^2
(2+ ML) * 2 =16
Divide each side by 2
(2+ ML) = 8
Subtract 2 from each side
ML = 6

A researcher selects a sample of participants to test for differences in employment rates among part-time and full-time teachers. Because there are many more women in teaching jobs than men, the researcher selected more women than men for her study to ensure that it represented the actual distribution of men and women teachers in the job sector. Which type of quota sampling was used in this example
Answer: proportionate
Step-by-step explanation:
Proportional quota sampling is when the total number of people that are to be surveyed are decided in advance. This form of sampling is usually used in opinion polls and surveys.
Since due to the fact that there are many more women in teaching jobs than men, the researcher selected more women than men for her study to ensure that it represented the actual distribution of men and women teachers in the job, then this was decided in advance and indicates the proportionate quota sampling.
3. Suppose that the interior angles of a convex hexagon are six
numbers, each separated by a value of 1 degree from its neighbors. What
is the measure of the third largest angle?
degrees
Answer:
The largest angle is A + 5 = 117.5 + 5 = 122.5 degree.
Step-by-step explanation:
The sum of the interior angles of a regular hexagon is 720 degree.
Let the one angle is A.
So,
A + A + 1 + A + 2 + A + 3 + A + 4 + A + 5 = 720
6 A + 15 = 720
6 A = 705
A = 117.5
The largest angle is A + 5 = 117.5 + 5 = 122.5 degree.

write short note on the rule on how to bisect a perpendicular angle
Answer:
Given a line segment AB
open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.
Call the two points where these two arcs meet C and D. Draw the line between C and D.
CD is the perpendicular bisector of the line segment AB. Call the point where CD intersects AB E.
Step-by-step explanation:
for more help please follow
Answer:
Follow the steps below to construct a perpendicular bisector of a line segment.
Step 1: Draw a line segment XY of any suitable length.
Step 2: Take a compass, and with X as the center and with more than half of the line segment XY as width, draw arcs above and below the line segment.
Step 3: Repeat the same step with Y as the center.
Step 4: Label the points of intersection as 'P' and 'Q'.
Step 5: Join the points 'P' and 'Q'. The point at which the perpendicular bisector PQ intersects the line segment XY is its midpoint. Label it as 'O'.

Ramiro tiene que reemplazar un vidrio roto de su casa, que tiene forma rectangular y mide 3,23m y 2,55m. Cuántos metros cuadrados de vidrio tiene que comprar
Answer:
8,24 metros cuadrados de vidrio
Step-by-step explanation:
Área de un rectángulo = Largo × Ancho
De la pregunta anterior
Longitud = 3,23 m
Ancho = 2,55 m
Área del rectángulo = 3,23 m × 2,55 m
= 8.2365 m²
Aproximadamente = 8,24 m²
Por tanto, Ramiro tiene que comprar 8,24 metros cuadrados de vidrio
how can you evaluate 36^1/2
Answer:
6
Step-by-step explanation:
======================================================
Explanation:
Exponents of 1/2 are the same as square roots
[tex]36^{1/2} = \sqrt{36} = 6[/tex]
If the exponent was say 1/3, then we'd be taking a cube root
[tex]36^{1/3} = \sqrt[3]{36}[/tex]
and this is what a fourth root would look like
[tex]36^{1/4} = \sqrt[4]{36}[/tex]

In a game of chess, a player can either
win, draw or lose.
The probability that Vishi wins any
game of chess is 0.5
The probability that Vishi draws any
game of chess is 0.3
Vishi plays two games of chess.
Work out the probability that Vishi will
lose exactly one of the two games.
Pls answer fast
Answer:
0.14
Step-by-step explanation:
If winning holds a probability of 0.5 and a draw holds a probability of 0.3, then that means that losing has a probability of 0.2 (1 - 0.5 - 0.7 = 0.2). Therefore, to find the probability of Vishi losing exactly one of the two games we need to multiply the probability of him losing one game by the probability of him winning or tying the second game like so...
0.2 * (0.5 + 0.3) = x
0.2 * 0.7 = x
0.14 = x
Finally, we can see that the probability of Vishi losing exactly one of the two games is 0.14
Is the Function exponential?
Answer:
y = 4x+ 5 is the equation that describes the data...
that is a linear equation ... the slope is 4 thus "the y value increases 4 for every 1 unit increase in x"
Step-by-step explanation:
(High points) please find the equation and explain. Legit answers only thank you
The x-intercept is when y=0. It is the point on the x-axis. Solve for x when y=0 in the first equation.
2x + 3(0) + 6 = 0
2x = -6
x = -3
x-intercept is (-3, 0).
The line we want has the same slope as the second equation because it is parallel. From the second equation,
-5y = -2x + 7
y = (2/5)x - (7/5)
The slope is 2/5.
Using the x-intercept and slope, along with the general form of the line y = mx + b , we can solve for b.
y = mx + b
0 = (2/5)(-3) + b
0 = (-6/5) + b
(6/5) = b
The equation we want is
y = (2/5)x + (6/5)

What is the measure of x?
Answer:
x=4
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(x+5) *x = 6^2
x^2 +5x = 36
Subtract 36 from each side
x^2 +5x - 36 = 0
Factor
( x-4) (x+9) = 0
Using the zero product property
x-4 = 0 x+9 =0
x = 4 x=-9
Cannot be negative since that is negative length
x=4

stay safe healthy and happy.A 16 foot ladder leaning against a wall makes a 66-degree angle with the ground. How far up the wall does the laddar reach?
Answer: About 15 feet off the ground
The more accurate value is 14.6167273222817 but even this value is not fully exact.
======================================================
Work Shown:
Refer to the diagram below.
sin(angle) = opposite/hypotenuse
sin(66) = x/16
16*sin(66) = x
x = 16*sin(66)
x = 14.6167273222817
x = 15
The ladder reaches roughly 15 feet off the ground, when rounding to the nearest whole number.
I'm rounding to the nearest whole number since the other length (16 ft) is a whole number. Round however you need to if your teacher instructs otherwise.
Today, the population of Canyon Falls is 22{,}50022,50022, comma, 500 and the population of Swift Creek is 15{,}20015,20015, comma, 200. The population of Canyon Falls is decreasing at the rate of 740740740 people each year while the population of Swift Creek is increasing at the rate of 1{,}5001,5001, comma, 500 people each year. Assuming these rates continue into the future, in how many years from today will the population of Swift Creek equal twice the population of Canyon Falls
Answer:
10 years
Step-by-step explanation:
Given :
Population of Canyon falls = 22500
Rate of decrease = 740 per year
Population after x years :
f(x) = 22500 - 740x ; x = number of years
Population of Swift Creek = 15200
Rate of Increase = 1500 per year
Population after x years :
f(x) = 15200 + 1500x ; x = number of years
Number of years when, population of swift creek will be twice that of Canyon falls
15200 + 1500x = 2(22500 - 740x)
15200 + 1500x = 45000 - 1480x
15200 - 45000 = - 1480x - 1500x
-29800 = - 2980x
x = 29800 / 2980
x = 10
After 10 years
