The surface area of the shape is 400 square yards
How to calculate the surface area of a shapeThe formula for calculating the surface area of the shape is given as:
Surface area = Area of square + area of triangle
Surface area = (15 * 20) + (0.5 * 10 * 20)
Surface area = 300 + 100
Surface area = 400 square yards
Hence the surface area of the shape is 400 square yards

Mark spent $35.50 at the mall. He bought one sweater and some socks. The sweater
cost $20.50 and each pair of socks cost $2.50 each. How many pairs of socks (s) did
Mark buy?
On January 1, Trisha put $100 into a savings account that earns interest. That same day, Mark put some money into another savings account that also earns interest. After 5 years, Trisha’s account balance is 145% of her original balance, and Mark’s is 160% of his original balance. Mark and Trisha withdraw all of their money and use it to spend $225 at the amusement park. If together they have $40 left from their withdrawals after the amusement park, how much did Mark put into his savings account?
Trisha thinks that if Mark also put $100 into his account, then they would had more than $100 left after the amusement park. Is she correct or not? Explain.
Answer:
Mark deposited $75Trisha is not correctStep-by-step explanation:
The total of their account balances is equal to the total spent plus the remaining amount. The given relations tell us ...
Trisha withdrew $100 × 145% = $145Mark withdrew d × 160% = 1.6d . . . for some initial deposit d$145 + 1.6d = $225 +40 . . . . . withdrawals = spent + change__
a.Solving this equation, we can find Mark's withdrawal and his initial deposit.
145 +1.6d = 265
1.6d = 120 . . . . . . . the amount Mark withdrew
d = 120/1.6 = 75 . . . . the amount Mark deposited
Mark put $75 into his savings account.
__
b.Had Mark put $100 into his savings account, the total of withdrawals would have been ...
Trisha + Mark = $100 × 145% +$100 ×160% = $145 +160 = $305
After spending $225 of this amount, they would have had a leftover amount of ...
$305 -225 = $80
Trisha is not correct in her thinking that there would be more than $100 left over.
Is the length of the hypotenuse of a right triangle with legs that measure 5 cm and 6 cm a rational number or an irrational number? Justify your answer.
Answer:
irrational
Step-by-step explanation:
Use the Pythagorean theorem.
5² + 6² = c²
25 + 36 = c²
c² = 61
7² = 49
6² = 64
61 is between 7² and 8², so it is not rational.

Answer:
11x + 10y - 2w
Step-by-step explanation:
Hello!
To solve for the perimeter, we add up the like terms.
What are like terms?
Like terms are terms with the same variable and degree. 4x and 5y are NOT like terms because the variable is not the same. However, 4x and 3x are like terms, as adding them gives us 7x.
4x and 4x² are not like terms, because the degree of 4x is 1 (degree means the largest exponent), but the degree of 4x² is 2.
Solve for Perimeter:
Combine the like terms by adding them up.
Perimeter = (8x - 4w) + (3y + 2w) + (3x + 7y)P = 8x - 4w + 3y + 2w + 3x + 7yP = 8x + 3x + 3y + 7y - 4w + 2wP = 11x + 10y - 2wThe perimeter is 11x + 10y - 2w

Answer:
see explanation
Step-by-step explanation:
the angles in a square are right .
the diagonals bisect the angles , then
∠ OKL = 45°
The diagonals are perpendicular to each other , then
∠ MOL = 90°
All sides are congruent , so
perimeter = 4 × NM = 4 × 8 = 32
Answer:
Perimeter: 32
measure of angle OKL: 45
measure of angle MOL: 90
Step-by-step explanation:
Things to remember:
- the side of the square are all equal
- vertical angles are congruent
+ ex. MON and KOL; MOL and NOK
- the entirety of the four angles in the center of the square equal 360 degrees
+ ex. MON + MOL + LOK + KON = 360 degrees
- corners of a square equal 90 degrees and since lines MK and LN cut the square in half we can assume that angles like OKL are also cut in half, making them 45 degrees
+ ex. angle NKL (90) = OKL (45) + OKN (45)
- The four triangles in the square are isosceles
If we have the angles of OML and MLO we can find MOL since the angles of a triangle equal 180
OML (45) + MLO (45) + MOL (x) = 180
90 + x = 180
x = 90

- Meagan puts three flowering plants in a garden bed. Plant 1 and Plant 2 are 6 inches apart Plant 2 and Plant 3 are 10 inches apart Plant 1 and Plant 3 are 13 inches apart Did Meagan place the plants in a right triangle shape? Why or why notp?
Answer:
No
Step-by-step explanation:
They can't be in a straight line because 6+10 (the distance between plants 1 and 2 and plants 2 and 3) is more than 13 which is the distance from plant 1 to plant 3. This means plant 3 can't be in line with 1 and 2 which will give a triangular shape. If we check Pythagorean theorem we get 6^2 + 10^2 = 13^2 ( the longest side has to be the hypotenuse) . Since this isn't a true statement it can't be a right triangle.

Step-by-step explanation:
Side 25=hypotenuse because it is across from the rightness of the triangleThis means that teh unknown side is a leg, as well as the side that says 16This makes our equation: a²+16²=25²Next we solve16²=256 and 25² is 625 so now our equation is a²+256=625We then subtract 256 from both sides which leaves us with x²=369To find the value of x, we take the square root of both sides. This leaves us with X=19.2What is the area of the shape?
Answer:
76
Step-by-step explanation:
to find the area of a square do base x height
7 x 8 = 56
to find the area of a triangle do base x height ÷ 2
3 x 8 = 24
24 ÷ 2 = 12
2 x 8 = 16
16 ÷ 2 = 8
8 + 12 + 56

A rectangle has an area of 108 square inches. The rectangle's length is 6 inches longer than 4
times its width.

What is the rectangle's width?
Write your answer as an integer, a simplified proper or improper fraction, or a simplified
radical expression
Considering the area of the rectangle, it is found that it's width of the rectangle is of 3 inches.
What is the area of a rectangle?The area of a rectangle of length l and width w is given by:
A = lw.
In this problem, we have that:
A = 108, l = 6 + 4w.
Hence, using the equation for the area:
lw = 108
(6 + 4w)w = 108
4w² + 6w - 108 = 0
2w² + 3w - 54 = 0
Which is a quadratic equation with coefficients a = 2, b = 3 and c = -54, hence:
[tex]\Delta = b^2 - 4ac = (3)^2 - 4(2)(-54) = 441[/tex]
[tex]x_1 = \frac{-3 + \sqrt{441}}{6} = 3[/tex]
[tex]x_2 = \frac{-3 - \sqrt{441}}{6} = -4[/tex]
Width is a positive measure, hence it is of 3 inches.
