Answer:
Approximately 16 feet
Step-by-step explanation:
If the playground has a square shape, then its area equals the square of the playground's side (S):
[tex]S^2=263 \,\,ft^2\\S = \sqrt{263} \,\,ft\\S\approx 16.217 \,\,ft \\S\approx 16\,\,ft[/tex]
Answer:
16 feet
Step-by-step explanation:
The area of a square can be found using the following formula.
[tex]A=s^2[/tex]
We know that the area of the playground is 263 ft^2. Therefore,
A=263 ft^2
[tex]263 ft^2= s^2[/tex]
We want to find out what s, the side length, is. s is being squared. The inverse of a square is a square root. Therefore, we must take the square root of both sides.
[tex]\sqrt{263 ft^2} =\sqrt{s^2}[/tex]
[tex]\sqrt{263ft^2}=s[/tex]
[tex]16.2172747 ft=s[/tex]
Round to the nearest foot. The 2 in the tenth place tells us to leave 16 as is.
[tex]16 ft=s[/tex]
The approximate length of each side of the playground is 16 feet.

what is the slope line through (0, 5) and (-2, -1)
Answer:
3 or 3/1
Step-by-step explanation:
Slope is also known as rise/run.
The formula used to find slope is y^2-y^1/x^2-x^1.
The work is below:
-1-5/0-2
-6/-2
3/1
m=3
When we calculate the slope using the formula, we find that the slope(m) equals to 3/1 or 3 which means that you rise up by 3 and run to the right 1.
Hope this helps!!! PLZ MARK BRAINLIEST!!!
The slope of the line through (0, 5) and (-2, -1) will be 3 or 3/1.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same). A measure of steepness is a slope. When building roads, one must determine how steep the road will be. These are some examples of slopes in real life.
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given the line is passed through the following points,
(x₁,y₁)=(0, 5)
(x₂,y₂)=(-2, -1)
The slope of the line is found as,
m=(y₂-y₁) / (x₂-x₁)
Substitute the given values,
m=-(1-5)/(0-2)
m=(-6)/(-2)
m=3/1
The slope(m) equals 3/1, or 3 when we compute the slope using the formula, meaning that you rise up by 3 and move to the right by 1.
Thus, the slope of the line through (0, 5) and (-2, -1) will be 3 or 3/1.

What is the solution to the equation 32x − 1 = 243? Question 18 options: A) x = 2 B) x = 3 C) x = 4 D) x = −2
Answer:
x = 4
Step-by-step explanation:
To solve this equation, first you want to write the whole thing out.
32x - 1 = 243
Next you want to get the variable by itself, so you are going to use inverse operations. in the equation, it is 32x - 1, so you are going to add one to both sides, getting you this:
32x = 244
Now for the final step you are going to get x alone, so you are going to use inverse operations once more and divide 32 on both sides getting you your answer.
x = 4
Now if you want to check your work simply plug in x, and if it is equal, you got the correct answer!
I hope this helped and good luck with your math!

Answer:
x = 4√3
y = 8√3
Step-by-step explanation:
This is a special 30° 60° 90° right triangle
In this special triangle if the side length that sees 30° is represented by x and the side length that sees 90° is represented by 2x and the side length that sees 60° x√3
Here, the side length that sees 60° is given as 12
12 = x√3 and x = 4√3 therefore y is 8√3
A lion can eat a sheep in 2 hours, a wolf can eat a sheep in 3 hours, and a dog can eat the sheep in 6 hours. How long would it take a lion, a wolf, and a dog all together to eat the poor sheep?
Answer:
1 hour
Step-by-step explanation:
The lion's speed is 1 sheep / 2 hours = ½ sheep/hour.
The wolf's speed is 1 sheep / 3 hours = ⅓ sheep/hour.
The dog's speed is 1 sheep / 6 hours = ⅙ sheep/hour.
Their combined speed is ½ + ⅓ + ⅙ = 1 sheep/hour.
So working together, it will take them 1 hour to eat 1 sheep.
Answer:
1 hour

Which statement is true of triangles P and Q? Triangle P has side lengths of 6, 8, 10 and angle measures of 53.1 degrees, 90 degrees, 36.9 degrees. Triangle Q has side lengths of 18, 24, 30 and angle measures of 53.1 degrees, 90 degrees, 36.9 degrees.
Answer:
Triangle P and Triangle Q are mathematically similar shapes (?).
Step-by-step explanation:
Hi, so the question asks which statement is true, given the following information, but you haven't written what statements we can choose from.
After reading the information, we can see that Triangle Q is the same shape as Triangle P but just larger.
I'm assuming that one of the statements given is about Triangle P and Triangle Q being mathematically similar shapes?
If you need to show your working out, here it is:
18 ÷ 6 = 3
24 ÷ 8 = 3
30 ÷ 10 = 3
All the angles are the same.
This means that the length scale factor is +3 from Triangle P to Triangle Q, the area scale factor is +9 (because 3 x 3 = 9) from Triangle P to Triangle Q, and that the two shapes are mathematically similar.
*DISCLAIMER* The majority of question askers on Brainly seem to be from the US, and I'm not, so the way I work things out / the mathematical terms I use might be different. Sorry!
Hope this helped anyway!

bob has to pack 192 boxes. this morning, he packed 84 boxes in 3 1/2 hours. if bob continues at the same rate, how long will it take him to pack the remaining boxes?
Answer:
4.5 hours
Step-by-step explanation:
Total number of boxes = 192
84 boxes = 3.5 hours
Remaining boxes = (192 - 84) = 108 boxes
84 boxes = 3.5 hours
1 box = (3.5 ÷ 8) hours
108 boxes = 3.5 × 108/84
108 boxes = 4.5 hours (Answer)
Answer:
4.5 hours! The person above me is is correct.

Answer:
1) AD=BC(corresponding parts of congruent triangles)
2)The value of x and y are 65 ° and 77.5° respectively
Step-by-step explanation:
1)
Given : AD||BC
AC bisects BD
So, AE=EC and BE=ED
We need to prove AD = BC
In ΔAED and ΔBEC
AE=EC (Given)
[tex]\angle AED = \angel BEC[/tex] ( Vertically opposite angles)
BE=ED (Given)
So, ΔAED ≅ ΔBEC (By SAS)
So, AD=BC(corresponding parts of congruent triangles)
Hence Proved
2)
Refer the attached figure
[tex]\angle ABC = 90^{\circ}[/tex]
In ΔDBC
BC=DC (Given)
So,[tex]\angle CDB=\angle DBC[/tex](Opposite angles of equal sides are equal)
So,[tex]\angle CDB=\angle DBC=x[/tex]
So,[tex]\angle CDB+\angle DBC+\angle BCD = 180^{\circ}[/tex] (Angle sum property)
x+x+50=180
2x+50=180
2x=130
x=65
So,[tex]\angle CDB=\angle DBC=x = 65^{\circ}[/tex]
Now,
[tex]\angle ABC = 90^{\circ}\\\angle ABC=\angle ABD+\angle DBC=\angle ABD+x=90[/tex]
So,[tex]\angle ABD=90-x=90-65=25^{\circ}[/tex]
In ΔABD
AB = BD (Given)
So,[tex]\angle BAD=\angle BDA[/tex](Opposite angles of equal sides are equal)
So,[tex]\angle BAD=\angle BDA=y[/tex]
So,[tex]\angle BAD+\angle BDA+\angle ABD = 180^{\circ}[/tex](Angle Sum property)
y+y+25=180
2y=180-25
2y=155
y=77.5
So, The value of x and y are 65 ° and 77.5° respectively
*PLEASE ANSWER* What is the perimeter of the triangle below?
Answer:
16.7 Units
Step-by-step explanation:
To find the length of r, you set up the equation as sin(45)= 4.9/r. Then you get r by itself changing it to r = 4.9/sin(45). Then you can find that r = 6.9. Since this is an isosceles triangle, n^1 has to be equal to 4.9. Then you add all the side lengths together. 4.9 + 4.9 + 6.9 = 16.7 units
