The area of a square is length*width and since a square has the same side measurements, √1225 or 35 is one side. (35 * 35 = 1225)
There are 4 sides so 35*4 = 140ft² as the perimeter
I hope this helps!
Answer:
140 ft
Step-by-step explanation:
Here, A = 1225 ft² = s², where s represents the length of one side of the room. Here, s = √( 1225 ft² ) = 35 ft.
Thus, the perimeter, P = 2L + 2W, is 4(35 ft) = 140 ft

A rectangular solid has sides of 10 cm, 6.5 cm, and 8.3 cm. What is its volume and surface area? Volume (to the nearest tenth) = cm3 Surface area (to the nearest tenth) = cm2
Answer:
V = 539.5 cm³SA = 403.9 cm²Step-by-step explanation:
The formula of a volume of a rectangular prism:
V = lwh
The fomula of a surface area of a rectangular prism:
SA = 2(lw + lh + wh)
l - length
w - width
h - height
We have l = 10cm, w = 6.5cm and h = 8.3cm. Substitute:
V = (10)(6.5)(8.3) = 539.5 cm³
SA = 2[(10)(6.5) + (10)(8.3) + (6.5)(8.3)] = 2(65 + 83 + 53.95)
= 2(201.95) = 403.9 cm²

Which equation represents the hyperbola in general form?
ANSWER
D.
[tex]9 {y}^{2} - 4 {x}^{2}- 36y + 16x - 16 = 0[/tex]
EXPLANATION
The standard equation of the hyperbola is
[tex] \frac{ {(y - 2)}^{2} }{4} - \frac{ {(x - 2)}^{2} }{9} = 1[/tex]
We multiply through by 36 to obtain:
[tex]9 {(y - 2)}^{2} - 4( {x - 2)}^{2} = 36[/tex]
We now expand to get,
[tex]9( {y}^{2} - 4y + 4) - 4( {x}^{2} - 4x + 4) = 36[/tex]
Expand :
[tex]9 {y}^{2} - 36y + 36 - 4 {x}^{2} + 16x - 16 = 36[/tex]
To get the general form, we equate everything to zero to get,
[tex]9 {y}^{2} - 4 {x}^{2}- 36y + 16x - 16 = 0[/tex]
The correct choice is D.

So in a gallon there is 4 quarts, and in 1 quart there are 2 pints and in 1 pint there are 2 cups.
So for the 1 quart of onion that would equal 4 cups. Then for the 4 pints of broth there would be 8 cups and then the 6 cups and 2 cups just stay the same. So if you add those number of cups up you would get 20 cups. Divide that by 4 to see how many bowls she would need.
The answer is she would need 5 bowls

D. 0.43, because 13 of the 30 days were cloudy
Step-by-step explanation:
The fist thing that you should do is divide 100 by 30. We will do this so taht our percentages add up to 100. When we do this we get 3.333. Next we need to multiply this by the nubert of cloudy days 13 to get the answer D.
ABE is a triangle. can you use the sss postulate or the sas postulate to prove triangle ABC is congruent to triangle AED?
1. Both apply
2. By SSS only
3.By SAS only
4. Neither apply
Postulate SAS can be used to prove triangle [tex]ABC[/tex] is congruent to triangle [tex]AED.[/tex]
What is triangle?" Triangle is defined as the two dimensional closed figure with three vertices, three sides, and three angles enclosed in it."
According to the question,
Given,
In triangle [tex]ABC[/tex] and [tex]AED[/tex]
[tex]\angle ADE = 120\° \ \ \ \ \ \ \ \ \ (1)[/tex]
[tex]\angle ACD = 60\°\\\\\angle ACD + \angle ACB = 180\° (linear \ pair)\\\\\implies \angle ACB = 180\° -60\°\\\\\implies \angle ACB = 120\° \ \ \ \ \ \ \ \ \ \ (2)[/tex]
From [tex](1)[/tex] and [tex](2)[/tex] we get
[tex]\angle ADE \cong \angle ACB[/tex]
[tex]AC \cong AD\\\\BC \cong ED[/tex]
By SAS postulate ,
Triangle ABC is congruent to triangle AED.
Hence, Option 3 is the correct answer.

Answer:
Part 1) [tex]42=\frac{1}{2}x(x-5)[/tex]
Part 2) The length of the base is [tex]x=12\ m[/tex]
Step-by-step explanation:
Part 1) Which equation would be help solve the following problem?
Let
x----> the length of the base of a triangle
y----> the height of a triangle
we know that
The area of a triangle is
[tex]A=\frac{1}{2}xy[/tex]
[tex]A=42\ m^{2}[/tex]
so
[tex]42=\frac{1}{2}xy[/tex] ------> equation A

Find the area of the trapezoid. Leave your answer in the simplest radical form. The figure is not drawn to scale.
96cm
The area of the rectangle is 72 (6 x 12)
The base of the left triangle is six and the height is six. Base x height is 36. 36/2 is 18.
The base of the right triangle is 2 and the height is 6. 6 x 2 is 12. 12/2 is 6.
6 plus 18 plus 72 is 96, which is the final answer.
ANSWER
[tex]96 {cm}^{2} [/tex]
EXPLANATION
The area of a tra-pezoid is calculated using the formula:
[tex]Area = \frac{1}{2} ( \: sum \: of \: bases )\: \times \: h[/tex]
[tex]Area = \frac{1}{2} ( \: sum \: of \: bases )\: \times \: h[/tex]
From the tra-pezoid
[tex] \tan(45 \degree) = \frac{6}{x} [/tex]
[tex]x = \frac{6}{\tan(45 \degree) } [/tex]
[tex]x = \frac{6}{1} = 6[/tex]
[tex]Area = \frac{1}{2} ( 12 + 20 )\: \times \: 6[/tex]
[tex]Area = \frac{1}{2} ( 32)\: \times \: 6[/tex]
[tex]Area =16 \times 6 = 96 {cm}^{2} [/tex]

If the volume of a sphere is 288πcm3, what is the radius of the sphere in centimeters?
Giving brainliest and 30 points!
The formula for volume of a sphere is 4/3 x PI x r^3
Solve for r:
288PI = 4/3 x PI x r^3
Divide both sides by PI:
288 = 4/3 x r^3
Divide both sides by 4/3:
216 = r^3
Take the cubic root of 216 for r:
r = ∛216
r = 6
The radius is 6 cm.

I NEED THE ANSWER PLEASE
Answer:
125.66 in. ³
Step-by-step explanation:
2 × π × r × h + 2 × π × r²
We only know the length of the diameter, but we have to find the radius. So we divide by 2 because the radius is half the diameter.
4 ÷ 2 = 2
So r = 2.
h = 8
2 × π × r × h
2 × 3.14 × 2 × 8 = 100.48
2 × π × r²
2 × 3.14 × 2²
2 × 3.14 × 4 = 25.12
Now add them up.
100.48 + 25.12 = 125.66

y= 89.5 + 0.409x Is a line of regression corresponding to a set of data which compares.
The number of commuters to number of paelinf spots at a given station.
The Metro-North Station of Greenwich, CT, has 2804 commuters. Find the predicted number of parking spots at the Metro-North Station.
A.) 1057 spots
B.) 2894 spots
C.) 6637 spots
D.) 1237 spots
Answer:
D.) 1237 spots
Step-by-step explanation:
We have been given the following regression line;
y= 89.5 + 0.409x
It is reasonable to argue that the number of commuters determines the number of parking spots and as such commuters is our explanatory variable (x). On the other hand, the number of parking spots is our response or dependent variable (y).
We are required to predict the number of parking spots at the Metro-North Station of Greenwich which has 2804 commuters. We are simply asked to determine the value of y when x is 2804 using the regression line;
y = 89.5 + 0.409(2804)
y = 1236.336
y = 1237
2x - 9y=14
[tex]2x - 9y = 14 [/tex]
Answer:
Step-by-step explanation:
first draw you line down on the equal sign take 2x and devide itso it should be 14/2 you should get 7 2x is no longer there then bring down 9y and add d to 14 thats 23 so its x =23
We need to solve for x.
2x - 9y = 14
Move the 9y to the right side and use inverse operations.
2x = 14 + 9y
Divide both sides of the equation by 2.
x = 7 + 9/2y or x = 7 + 4.5y

Solve for m. 7m + 8 = 8m
Answer:
8
Step-by-step explanation:
7m+8=8m
7m-8m= -8
Whenever you move a number for the opposite side , you change the sign. For example, the number is 6 , then you move it to the other side. The sign becomes negative 6.
-m=-8
The m cannot be a negative sign. So you multiply it by -1 and for -8.
-1(-m)= -1(-8)
m= 8
Double check answer if you want to:
7m+8=8m
Substitute the answer for m.
7(8)+8=8(8)
64=64
So the answer is correct. m=8

answer for this question is 3.85 units squared
Answer:
[tex]\boxed{\text{38.5 units}^{2}}[/tex]
Step-by-step explanation:
The polygon is a trapezoid on its side.
The formula for the area of a trapezoid is
A = ½(a + b)h,
where a and b are the lengths of the parallel sides and h is the distance between them.
AD = a = 2 – (-2) = 2 + 2 = 4 units
BC = b = 2 – (-5) = 2 + 5 = 7 units
AB = h = 3 – (-4) = 3 + 4 = 7 units
A = ½(4 + 7) × 7 = ½ × 11 × 7 = 38.5 units²

Which function has zeros at x = −2 and x = 5?
f(x) = x2 + 2x − 10
f(x) = x2 − 2x − 10
f(x) = x2 + 3x − 10
f(x) = x2 − 3x − 10
f(x)=X2+3x-10 for X=-2
why? 2*2+3*2-10
4+6-10=0
Answer: f(x) = x2 - 3x -10
Step-by-step explanation:
putting x= -2
f(-2) = (-2)^2 - 3(-2) - 10
=4 + 6 -10
f(-2)=0
f(5) = x2 - 3x - 10
= (5)^2 - 3(5) -10
=25 - 15 - 10
f(5) =0

Which of the following ratios are equivalent to 4:5?
12:15
36 to 40
16 to 20
Answer:
12:15
16:20
Step-by-step explanation:
Note that what you multiply to one side, you multiply to the other (same with dividing) for ratios.
4:5 => 4 * 3: 5 * 3 = 12:15
4:5 => 4 * 4: 5 * 4 = 16:20

Answer:
12:5 and 16:20 are equalevent to 4:5
Step-by-step explanation:
12 divided by 3 = 4 (Because 3 x 4 = 12)
15 ÷ 3 =5 (because 5 x 3 = 15, we basicly raised the ration by a scale factor of 3)
12:15 = 4:5
16 ÷ 4 = 4 (because 4 x 4 = 16)
20 ÷ 4 = 5 (4 x 5 = 20 This ratio was raised by a scale factor of 4)
16 : 20 = 4:5
12:5 and 16:20
