The perimeter of a square is 24 feet. What is the area in square feet
Answers
Answer:
Step-by-step explanation:
Remark
You need 2 formulas to solve this. Use perimeter first and then area.
Formulas
P = 4s
Area = s^2
Givens
Perimeter = 24 feet
Solution
P = 4*s Substitute the value for P
24 feet = 4s Divide both sides by 4
24/4 = 4s/4
6 = s
Now use the area formula
Area = s^2 Substitute 6 for s
Area = 6^2
Area = 36 feet^2
Answer
Area = 36 ft^2
The perimeter of a square is 24 feet. What is the area in square feet.
Explanation -:In this question we are provided with the perimeter of the square and we are asked to calculate the area of the square. First we will calculate the side of the square and then we will calculate the area.
[tex] \small{ \underline{ \underline{ \red{\rm{ Calculating \: the \: side \: of \: the \: square}}}}}[/tex]
We know,
[tex] \star \: \small\boxed{ \rm{ Perimeter_{(square)} = 4 × side}}[/tex]
Substituting the values we get
[tex] \small\bf 24 = 4 × s[/tex]
[tex] \small\sf{ → \dfrac{24}{4} = s}[/tex]
[tex] \small\sf{ → s = 6 \: feet}[/tex]
[tex] \small{ \underline{ \underline{\rm \red{ Now, we \: will \: calculate \: the \: area }}}}[/tex]
We know,
[tex] \star \: \small \boxed{{\rm Area_{(square)} = side × side}}[/tex]
Substituting the values we get
[tex] \small\rm {Area_{(square)} = (6 × 6) feet² = 36 \: feet²}[/tex]
Hence, the area of the square is 36 feet².

Answer:
a) angle QRP is 92 degrees, side QR is 23 cm, angle RPQ is 47 degrees
b) angle EFD is 65 degrees, side FD is 22cm, side ED is 20cm
Step-by-step explanation:
a) in the first example, you know that u are given QR, PR, and angle PRQ, and u are asked to find triangle PQR,or the rest of the lengths.
step 1-u draw an example of the triangle, i will provide one for each at the bottom of this answer
step 2-lets find the sides first with the pythagorean theorem, which will mean 25²+x²=34². Pythagorean theorem is a²+b²=c²
step 3-after solving for x, x will be 23.04, which means the third side is 23 cm (after rounding).
step 4-now that we have all the sides, we can solve for the rest of the angles, by trigonometric ratios, we are gonna use sine for angle RPQ, sine is sin(the angle u want to find)=opposite side/hypotenuse.
step 5- so sin(RPQ)=25/34, and solve for RPQ on a calculator (i used math) and angle RPQ will equal 47.3 degrees.
step 6- just subtract the sum of both angles from 180 an the last angle will be 92 degrees.
b) u are given the measure of angles FED and EDF and the side length FE, we will solve for the last angle first then we will go for the side engths
step 1- we subtract the sum of the two angles we have from 180 and we will get the measure of angle EFD to be 65 degrees, now we have the angles and we want to find he sides.
step 2-we use sine of angle 31 degrees to find the hypotenuse, but it is opposite of sine since we want to find the side, not the angle, so we will use sin(31)=11.3/x, the sine equation is written like sin(the angle u have)=opposite/hypotenuse.
step 3- after solving for arc sine in a calculator, u will find side FD to be 22cm, and now to find the last side.
step 4-i will use the sine of angle 65 degrees to solve for side ED, it will be sin(65)=x/22, which will make side ED equal 20 cm in length.
ur welcome :)

Answer: 34
Step-by-step explanation:
Mean is the same as average, and to find average you add all the numbers up and divide by the amount of numbers present. So, if you add all of them up, you get 238. Then, you'll divide by 7, since there are 7 numbers. And that will get you 34.
Prove: (sin α + cos β)^2 + (cos β + sin α)(cos β − sin α) = 2 cos β(sin α + cos β)
Answers
The two terms on the left side both have a common factor of (sin(α) + cos(β)), so we can pull it out like so:
(sin(α) + cos(β))² + (cos(β) + sin(α)) (cos(β) - sin(α))
= (sin(α) + cos(β)) [(sin(α) + cos(β)) + (cos(β) - sin(α))]
= (sin(α) + cos(β)) (sin(α) + cos(β) + cos(β) - sin(α))
= 2 cos(β) (sin(α) + cos(β))

What is the probability of picking a 7 and then picking a 5?
Write your answer as a fraction or whole number.
Answers
Answer:
The probability is 1/9
Step-by-step explanation:
1/3 x 1/3 = 1/9
Reason:
The probability of selecting "7" is 1/3 because there's one card labeled "7" out of three cards total.
The same applies to selecting a "5" as well. When the first card is put back, effectively nothing has changed.
The probability of getting a "7", then getting a "5" is (1/3)*(1/3) = 1/9

Derivative of y^2 becomes 2y * dy/dt.
4(t+1) can be distributed to equal 4t + 4.
Derivative of 4t + 4 becomes 4.
Therefore, a possible differential equation is dy/dt * 2y = 4. Can check by separating and integrating.
