The perimeter of a square is 52 cm.
Calculate the area of the square.
Answer:
169 [tex]cm^{2}[/tex]
Step-by-step explanation:
Ok so we know that perimeter is when you add up all the side lengths of a given shape. Since we know it's 52, we can use that to help us!
A square means that all 4 sides are equal; all 4 side lengths are equal...
Now we can divide the perimeter by 4 (a square has 4 sides) to get the side lengths for one side of the square (when we get one side, we automatically have the other sides)
52 ÷ 4 = 13
The side lengths for the square is 13
Check...
13 + 13 + 13 + 13 = 52 CORRECT
Now that we have the side of the square, we can find the area...
A = b * h
A = 13 * 13
A = 169 [tex]cm^{2}[/tex]
The area of the square is 169 [tex]cm^{2}[/tex]
Hope this helped!

Answer: 169 cm²
Step-by-step explanation: Remember that the formula
for the perimeter of a square is 4 times a side.
Therefore, since the perimeter of the given square is 52,
we have 52 = 4s and dividing both sides by 4, 13 = s.
Now, remember that the formula for the area of a square is s² and since
the length of a side of a given square is 13, we have (13)² or 169.
So the area of a square that has a perimeter of 52 cm is 169 cm².
Notice that we include square centimeters in our final answer because
we were given centimeters as our units in the original problem.

Evaluate (2.4x10^4) (4.5x10^3)
Answer:
108000000x^2
Step-by-step explanation:
The given expression (2.4 × 10⁴) (4.5 × 10³) becomes 1.08 × 10⁸ after performing the operations.
To evaluate the expression (2.4 × 10⁴) (4.5 × 10³), we use the properties of exponents.
When multiplying numbers written in scientific notation, we multiply the coefficients and add the exponents.
(2.4 × 10⁴) (4.5 × 10³) = (2.4 × 4.5) × (10⁴ × 10³)
= 10.8 × 10⁷
Next, we simplify the result by adding the exponents since the base (10) is the same:
10.8 × 10⁷ = 1.08 × 10⁸
Therefore, the final result of the expression is 1.08 × 10⁸.

Answer:
m∠P = 105°
QR = 11.6
m∠M = 45°
LN = 8.5
Step-by-step explanation:
Given:
ΔLMN ≅ ΔPQR
By the property of congruence,
Sides of the congruent triangles will be equal in measure (SSS property of congruence)
LN = PR = 8.5
QR = MN = 11.6
Since, both the triangles are congruent, they will follow ASA postulate of congruence,
m∠P = m∠L = 105°
m∠M = m∠Q = 45°

From the equation y−3=−2(x+1), identify the slope and a point on the line.
Answer:
slope = - 2, point on line = (- 1, 3 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 2(x + 1) ← is in point- slope form
with slope m = - 2 and (a, b ) = (- 1, 3 )
The slope of equation y−3=−2(x+1) is -2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
y−3=−2(x+1)
Using Slope- Intercept form
y= mx + b
So, the slope for the equation is -2.
Hence, the slope is -2.

In this triangle cosA/cosB= blank
Answer:
1
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.
Trigonometric functions are used to show the relationship between the angles of a triangles and the sides of the triangle. For a right angled triangle, the ratio of the sides can be gotten using trigonometric functions such as:
cosθ = adjacent/hypotenuse, sinθ = opposite/hypotenuse, tanθ = opposite/adjacent
Given the right angle triangle:
cos(A) = adjacent / hypotenuse = 3 / 4.24
cos(A) = 3 / 4.25
cos(B) = adjacent / hypotenuse = 3 / 4.24
cos(B) = 3 / 4.24
cos(A) / cos(B) = (3 / 4.24) ÷ (3 / 4.24) = 1
cos(A) / cos(B) = 1

If a thousand dollars is put into a bank account each year the account earns 7% simple interest in 4 years how much interest would it have gained
Answer:
$280
Step-by-step explanation:
According to the problem, calculation of the given data are as follows:
Principal amount (P) = $1,000
Rate of interest (r) = 7%
Time period (t) = 4 years
Here we use simple interest formula to calculate interest after 4 years.
I = P × r × t
By putting the value, we get
I = $1,000 × 7% × 4
= $70 × 4
= $280

The surface area of the shoe box is,
⇒ SA = 418 square inches
We have to given that,
A shoe box has a length of 14.5 inches, a width of 7 inches, and a height of 5 inches.
Since, We know that,
Surface area of cuboid is,
SA = 2 (lw + lh + hw)
Here, we have;
Length = 14,5
Width = 7 inches
Height = 5 inches
Hence, We get;
The surface area of the shoe box is,
SA = 2 (14.5 x 7 + 14.5 x 5 + 5 x 7)
SA = 2 (101.5 + 72.5 + 35)
SA = 2 (209)
SA = 418 square inches
Thus, The surface area of the shoe box is,
⇒ SA = 418 square inches
