Answer:
92 meters high.
Step-by-step explanation:
This problem involves proportion.
Let x be the unknown, which is the height of the building.
height of pole = height of the building
height of the shadow height of the shadow
3.3 m = x
1.78 m 49. 75 m
Solve for x.
(3.3 m) (49.75 m) = x
1.78 m
92.2331460674 = x
Rounded to the nearest meter, the building is 92 meters high.

Which equation can be used to find the answer?
A fence with four sections has a perimeter of 43 ft. Three of the sections have lengths of 8 ft, 12 ft, and 11 ft. What is the length of the fourth section?
x = 43 + 8 + 12 + 11
x + 8 + 12 + 11 = 43
x – 8 + 12 +11 = 43
x – 43 = 8 + 12 –11
Answer:
x + 8 + 12 + 11 = 43
Step-by-step explanation:
The perimeter is the length of the 4 sections of fencing.
If x represents the fourth section and the perimeter is 43, then
x + 8 + 12 + 11 = 43, that is
x + 31 = 43 ( subtract 31 from both sides )
x = 12
The length of the fourth section is 12 ft
Which situation results in a final value of zero?
A. The overall change in temperature when the temperature goes from -10 degrees fahrenheit, to 10 degrees fahrenheit.
B. The total profit made from when a person buys an item for $2.25, and then sells the item for $2.25.
C. The overall change in altitude in a hot air balloon after rising 21 kilometers from sea level.
D. The total distance a person travels when he bikes 3.1 miles to school and the bikes 3.1 miles back home.
Answer:
B
Step-by-step explanation:
The profit made is equal to 2.25-2.25 which is 0.
The situation "the total profit is made when a person buys an item for $2.25 and then sells the item for $2.25" is result in a final value of zero. which is the correct answer would be an option (B).
What is the distance?Distance is defined as the product of speed and time.
As per option (A),
The overall change in temperature = 10 - (-10) = 20 degrees
As per option (B),
The profit made is equal to 2.25 - 2.25 = 0 which is zero.
As per option (C),
The overall change in altitude = 21 - 0 = 21 kilometers
As per option (D),
The total distance traveled by person = 3.1 + 3.1 = 6.2 miles
Thus, the situation "the total profit is made when a person buys an item for $2.25 and then sells the item for $2.25" is result in a final value of zero.
Hence, the correct answer would be option (B).

In ΔGHI, the measure of ∠I=90°, the measure of ∠G=34°, and HI = 7 feet. Find the length of GH to the nearest tenth of a foot.
Answer:
GH ≈ 12.5 ft
Step-by-step explanation:
Using the sine ratio in the right triangle
sin34° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{HI}{GH}[/tex] = [tex]\frac{7}{GH}[/tex] ( multiply both sides by GH )
GH × sin34° = 7 ( divide both sides by sin34° )
GH = [tex]\frac{7}{sin34}[/tex] ≈ 12.5 ft ( to the nearest tenth )

[tex](2.7 * 10^{-5}) / (9 * 10^{-6})[/tex]
Answer:
3
Step-by-step explanation:
2.7 * 10 ^-5 / 9 * 10 ^-6
First divide the numbers
2.7 / 9 = .3
Then divide the exponents
10^-5 / 10 ^ -6
When we divide exponents we subtract
10^(-5 - -6) = 10 ^1
.3 * 10 ^1
But scientific notation has a number between 1 and less than 10
Move the decimal 1 place to the left, so we subtract 1 from the exponent
3 * 10 ^ (1-1)
3 * 10 ^0

Answer:
Step 2Step-by-step explanation:
Given the quadratic equation 6x² + 24x + 7 = 0, the following steps must be followed when finding the roots using the completing the square method.
Step 1: Subtract 7 from both sides
6x² + 24x + 7 - 7= 0 -7
6x² + 24x = -7
Step 2: divide through by the coefficient of x²
6x²/6 + 24x/6 = -7/6
x² + 4x = -7/6
Step 3: Add half of the coefficient of x (i.e 4/2 = 2) to both sides of the equation to complete the square of the equation x² + 4x.
x² + 4x + 2= -7/6 + 2
(x+2)² = -7/6 + 2
(x+2)² = 5/6
Step 4: taking the square root of both sides
√(x+2)² = √5/6
x+2 = ±√5/6
x = -2±√5/6
x = -2+√5/6 and -2-√5/6
Based on the conclusion above, it can be seen that Yvonne made the first error in step 2. Yvonne suppose to divide through by the coefficient of x² (i.e 6)

Find two numbers whose square increased by 15 equals 8 times the number.
Answer:5 and 3
So we let the number take the letter b, anc the expression of the question is:
b^2+15=8×b.....so
b^2+15=8b
Then we take the 8b to the other side of the equal sign so that it becomes...
b^2+15-8b=0
Hence it becomes a quadatic equation following the principle ax^2+bx+c where x is the unknown...
From there we work out to get two different numbers...either b-5=0
b=5
Or b-3=0
b=3
So the two numbers are 5 and 3
The volume of a cylinder is 576Pi cubic inches. The radius of the circular base is 4 inches. What is the height of the cylinder? Recall the formula V = pi r squared h. 18 inches 24 inches 36 inches 72 inches
Answer: 36 inches
Step-by-step explanation:
Since we know that the volume of the cylinder is 576π and that the radius is 4 inches, we can fill in the given numbers before solving the unknown.
V = π * 4^2 * h
π(pi) is the same as 3.14
4^2 is the same as 4 * 4 which is 16
Volume = 1,808.64 (576π)
First, we will be replacing the variables with the given numbers:
V = π * 4^2 * h --> 1,808.64 = 3.14 * 16 * h
To get the unknown, we first have to make sure it is by itself. To do that, we must divide 1,808.64 by 3.14 which is 576. Now we have 576 = 16 * h, to get to 'h', we must divide one more time, 576 divided by 16 is 36.
We are left with 36 = h. So the final answer is 36.

Find the area of rectangle PLUM.
Answer:
Area of rectangle PLUM = 75.00 square units
Step-by-step explanation:
Since diagonal of rectangle divides the rectangle into two equal triangles,
Therefore, area of the rectangle PLUM = 2× area of triangle PLM
By the mean proportional theorem,
In ΔPLM,
AP² = AM × AL
6² = AM × 8
AM = [tex]\frac{36}{8}[/tex]
AM = 4.5 units
Area of PLM = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]
= [tex]\frac{1}{2}(ML)(AP)[/tex]
= [tex]\frac{1}{2}(8 + 4.5)(6)[/tex]
= 12.5 × 3
= 37.5 units²
Now area of rectangle PLUM = 2×37.5 = 75 units²
Therefore, area of the rectangle is 75.00 square units.

there was a seller of horses, who sold all his horses to three people. To the first man he sold half of all his horses and a half of a horse. to the second man he sold half of what he had left and half of a horse. To the third man he again sold half of what was left and a half of a horse. How many horses did he have at first?
Answer:
17
Step-by-step explanation:
The total number of horses he had at first was 7 horses.
What are word problems?Word problems in mathematics involve careful understanding and they are those methods we use in solving real-life cases by using:
Basic arithmetic operations, Fractions, and/orAlgebraic expressions etc.From the given information:
Let the half of all his horses to the first man be x and half of a horse be yLet half of what is left to the second man be z and half of a horse be yLet half of what is left to the third man be a and half of a horse be y.Then, we can have the system of equations for the three cases to be:
[tex]\mathbf{\dfrac{1}{2}x + \dfrac{1}{2}y = 3 ---- (1)}[/tex]
Making (y) the subject and ignoring (x), we have:
[tex]\mathbf{y = \dfrac{3 - \dfrac{1}{2}}{\dfrac{1}{2}} = 5}[/tex]
y = 5
For the second man;
[tex]\mathbf{\dfrac{1}{2}z + \dfrac{1}{2}y = 3 ---- (2)}[/tex]
[tex]\mathbf{z= \dfrac{3 - \dfrac{1}{2}(5)}{\dfrac{1}{2}} = 1}[/tex]
z = 1
For the third man:
[tex]\mathbf{\dfrac{1}{2}a + \dfrac{1}{2}y = 3 ---- (2)}[/tex]
[tex]\mathbf{a= \dfrac{3 - \dfrac{1}{2}(5)}{\dfrac{1}{2}} = 1}[/tex]
a = 1
Thus, the total number of horses he had at first were:
= 5 + 1 + 1
= 7 horses
