Answer:
23. 42 m^2
24. 144 ft^2
25. 68 cm^2
Step-by-step explanation:
The teacher should not need to spend any time teaching this. The area of the total figure is the sum of the areas of its parts. You already know that. And, you already know how to compute the areas of triangles and rectangles.
__
You may recall that the area of a triangle is ...
A = 1/2bh
and the area of a rectangle with the same base and height is ...
A = bh
So, a triangle with base b and height h has the same area as a rectangle with the same base (b) and half the height (h/2). Recognizing this makes these problems really simple.
__
23. The base of the rectangle and triangle is 7 m. The height of the triangle is 4 m, so its area is equivalent to adding 4/2 = 2 m to the 4 m height of the rectangle. Then the total area is ...
A = (7 m)(4 m +(1/2)(4 m)) = (7 m)(6 m) = 42 m^2
__
24. Since there are two identical triangles of height 5, their total area is equal to that of a rectangle of height 5.
A = (12 ft)(7 ft +5 ft) = 144 ft^2
__
25. The 5 cm height of the triangle makes it have an area equivalent to a rectangle 5/2 cm high.
A = (8 cm)(6 cm +5/2 cm) = 68 cm^2
Note: we have read the fuzzy numbers as 8 cm wide, 6 cm high for the rectangle, and 5 cm high for the triangle. If your figure is different, please use the appropriate numbers in the calculation.
can some one simplify for x
12=7x+6-5x
Answer:
x = 3
Step-by-step explanation:
12 = 7x + 6 -5x {Combine like terms}
12 = 7x - 5x + 6
12 = 2x + 6 {Subtract 6 from both sides}
12 - 6 = 2x
6 = 2x {Divide both sides by 2}
6/2 = 2x/2
3 = x
x = 3
Solve: −6x+4≤−16−2x . Express your answer in interval notation. (Express your answer in interval notation. Use U to indicate a union of intervals, and "oo" to express ∞)
Answer:
[5, oo)
Step-by-step explanation:
Add 6x+16 to both sides:
20 ≤ 4x
5 ≤ x . . . . . . divide by 4
The solution interval is [5, oo).

8 Level Problems (Challenging, Unfamiliar)
4. In a right triangle, the hypotenuse is 3 times the length of the shorter leg. The longer leg is 5cm. Find
the length of the hypotenuse.
h = 15√3/4
= 6.4875
≈ 6.5 cm
Step-by-step explanation:h = 3x
c₁ = 5 cm
c₂ = x
Pythagorash² = c₁² + c₂²
(3x)² = 5² + x²
9x² = 25 + x²
8x² = 25
x² = 25/8
x = √25/8
x = 5/2√2
x = 5√2/4
h = 3x
= 3×5√2/4
= 15√2/4 cm
Question 3 of 10
Is ACOW- APIG? If so, identify the similarity postulate or theorem that
applies
Explanation:
Choice A isn't the answer because we don't know anything about the angles, so we can't use the AA (angle angle) Similarity theorem.
Choice B isn't the answer because we don't have info about all three pairs of sides (we only have two pairs of sides).
Choice C isn't the answer in a similar way choice A isn't either. We don't know anything about the angles, so we can't use the "A" in "SAS".
Choice D is the only thing left. It turns out we don't have enough info to be able to determine if the triangles are similar or not.
i just need some help honestly
Since PQ = QR = RS,
Let's set PQ equal to RS
2x + 3 = x + 10
Subtract x and 3 from both sides.
x = 7
PQ = 2x + 3 = 2(7) + 3 = 14 + 3 = 17
Since PQ = QR = RS,
QR = 17
There are three consecutive integers. Four times the smallest integer is equal to six more than three times the smallest integer. What is the smallest of the 3 integers?
Let the smallest integer equal x - 1, the next one equal x, and the last one equal x + 1.
4(x-1) = 3(x-1) + 6
x-1 = 5
x = 6
The smallest integer is x - 1, which is equal to 5. Thus, the smallest of the three integers is 5.

What's the value of x to the nearest tenth? Question 12 options: A) 7.9 B) 9.7 C) 5.9 D) 8.1
Answer:
The value is 9.7
Step-by-step explanation:
Use the Pythagorean theorem. [tex]a^{2} + b^{2}= c^{2}[/tex]
a=7 b=x c=12
[tex]7^{2} + x^{2}= 12^{2}[/tex]
[tex]49+x^{2} =144[/tex]
[tex]144-49=95[/tex]
[tex]x^{2} =95[/tex]
[tex]\sqrt{ x^{2}} =\sqrt{95}[/tex]
x=9.74679434481
x=9.7
If you're going 60 miles per hour, how many hours is that? So, in other words, what does "per" mean? How many is "per"?
Answer:
Per pretty much means 1. So for example if I say I'm going 12 miles PER hour it means 12 miles every 1 hour.

Answer:
[tex]GH=2\sqrt{10}[/tex]
Step-by-step explanation:
Considering each is square is 1x1.
We have the points G(-2, -3) and H(0, 3).
Using the distance formula:
[tex]$d=\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$[/tex]
[tex]$d=\sqrt{(-2 - 0)^2 + (-3 - 3)^2}$[/tex]
[tex]$d=\sqrt{(-2 )^2 + (-6)^2}$[/tex]
[tex]$d=\sqrt{4 +36}$[/tex]
[tex]d=\sqrt{40}=2\sqrt{10}[/tex]
Also, using the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]
[tex]2^2+6^2=c^2[/tex]
[tex]4+36=c^2[/tex]
[tex]c=GH=\sqrt{40}=2\sqrt{10}[/tex]
Bethany makes 50 hotdogs to divide equally between 6 people. How many hotdogs does each person get?
Step-by-step explanation:
soltion
hotdog=50
people =6
dividing equally to each people
A person got=50/6
=8.33
so each got 8.33
but practically we cannot give it 8.33 to each so we can give 8 to each

average age of the whole class."
Answer:
class has 30 boys and 20 girls the average age of boys is 12yr and girls 12yrwhole age of class is 12 + 12 ÷2
= 24÷2
= 12
Step-by-step explanation:
so the average of whole class is 121 What is an appropriate "2nd step" when solving the equation below? 2/3x - 8= 12 Add 8 to each side. Divide both sides by 3. Multiply both sides by 2. Multiply both sides by 3/2.
Answer:
multiply both sides by [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] x - 8 = 12
first step
Add 8 to both sides
[tex]\frac{2}{3}[/tex] x = 20
second step
Multiply both sides by [tex]\frac{3}{2}[/tex] to clear the fraction
x = [tex]\frac{3}{2}[/tex] × 20 = 30
