Area =
2. H = 8 in.
B = 15 in.
Answer:
1) 30 in²
2) 60 in²
Step-by-step explanation:
a = (1/2)bh
----------------------
h = 4
b = 15
a = 1/2 * 4 * 15
a = 30 in²

h = 8
b = 15
a = 1/2 * 8 * 15
a = 60 in²

Each envelope in the class contains the same number of triangles and quadrilaterals. Write an expression that
represents the total number of sides in the room.
Answer: 3t+4q.
Step-by-step explanation: Triangles have 3 sides, so there will be 3 sides for each triangle in the envelope. This is represented by 3t. Quadrilaterals have 4 sides, so there will be 4 sides for each quadrilateral in the envelope. This is represented by 4q. The total number of sides will be the number of triangle sides and the number of quadrilateral sides together.

Last month, he sold 50 chickens and 30 ducks for $550. This month, he sold 44 chickens and 36 ducks for $532
Answer:
★ Given :
Cost of 50 chickens and 30 ducks = $ 550
Cost of 44 chickens and 36 ducks = $ 532
★ To find :
Cost of chicken and duck
★ Solution :
Assume :
Cost of chicken = x
Cost of duck = y
According to question :
50x + 30y = 550 ......(1)
44x + 36y = 532......(2)
1) - (2)
(50x + 30y) - (44x + 36y) = 550 - 532
50x + 30y - 44x - 36y = 18
6x - 6y = 18
6(x - y) = 18
x - y = 18/6
→ x - y = 3 ....(3)
In equation 1 ,
50 x + 30y = 550
taking 10 common
10(5x + 3y) = 550
5x + 3y = 550/10
5x + 3y = 55
by taking 3 common
3(5/3 x + y) = 55
by dividing 3 on both sides
5/3x + y = 55/3 .....(4)
(3) + (4)
x - y + 5/3 x + y = 3 + 55/3
x + 5/3 x = 64/3
8/3 x = 64/3
by multiplying 3 on both sides
8x = 64
x = 64/8
→ x = 8
→ Cost of chicken = $ 8 ..
by putting value of x in equation 3
x - y = 3
8 - y = 3
y = 8 - 3
→ y = 5
→ Cost of ducks = $5..

x is the short leg of the triangle, located across from the 30° angle. (In this problem, the short leg is labled b)
The hypotenuse leg is across from the right angle, and is always 2x (In this problem, the hypotenuse leg is labled c)
The long leg of the triangle is located across the 60° angle and is always x√3. (in this problem, the long leg is labeled a)
The perimeter of a rectangular wooden deck is 90 feet. The deck's length is 5 feet less than 4 times its width. Write a system of equations to represent this situation.
Answer:
width = w
length = 4w - 5
perimeter = 90 feet
substitute these values into the formula for perimeter of a rectangle
90ft = 2( w + 4w - 5)
90ft = 2( 5w - 5)
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)

Answer:
60
Step-by-step explanation:
If Isabelle sells 150 out of 250 ears of corn. Then the percentage of the ears of corn she sold will be 60%.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
Every morning she starts with 250 ears of corn.
On Saturday, Isabelle sells 150 out of 250 ears of corn.
Then the percentage of the ears of corn she sold will be
[tex]\rm P = \dfrac{150}{250} \times 100\\\\P = 15 \times 4\\\\P = 60 \%[/tex]
