A firefighter is standing 33 feet away from a 45 foot tall building. The firefighter looks up and sees that a cat that is stuck on the top of the building and also notices a dog in a second flooor window that is 15 feet above ground. What is the angle of elevation of the cat?

Answers

Answer 1

Given :

Distance of firefighter from the building, D = 33 feet.

Height of building, h = 45 feet.

To Find :

The angle of elevation of the cat.

Solution :

Let, angle of elevation is Ф.

We know, tan Ф = h/D

tan Ф = 45/33

Ф = tan⁻¹( 45/33 )

Ф = 53.75°

Therefore, angle of elevation is 53.75° .

Hence, this is the required solution.

What is the value of x?

Enter your answer in the box.

Answers

Answer:

111°

Step-by-step explanation:

The polygon given is a heptagon having 7 sides.

Sum of interior angles of a 7-sided polygon = (n - 2)*180

= (7 - 2)*180

= 5*180 = 900°

Therefore:

126° + 158° + 120° + 125° + 121° + 139° + x° = 900°

Solve for x

789° + x° = 900°

Subtract 789 from each side

x = 900° - 789°

x = 111°

During a 60-minute period, a traffic engineer counted 66 trucks and cars that crossed a bridge. The ratio of trucks to cars that travel across the bridge is usually 3:8. The equation 3 8 = t 66 − t 3 8 = t 66 − t can be used to predict the number of trucks, t, the engineer should have counted. How many trucks should the engineer have counted?

Answers

Answer:

18

Step-by-step explanation:

t = Number of trucks counted

c = Number of cars

Ratio of trucks to cars = [tex]\dfrac{t}{c}=\dfrac{3}{8}[/tex]

Total number of cars and truck = 66

[tex]t+c=66[/tex]

Divide the left and right side by the number of cars

[tex]\dfrac{t+c}{c}=\dfrac{66}{c}\\\Rightarrow \dfrac{t}{c}+1=\dfrac{66}{c}\\\Rightarrow \dfrac{3}{8}+1=\dfrac{66}{c}\\\Rightarrow \dfrac{11}{8}=\dfrac{66}{c}\\\Rightarrow c=66\times \dfrac{8}{11}\\\Rightarrow c=48[/tex]

Total number of cars is 48

so

[tex]t=66-c\\\Rightarrow t=66-48\\\Rightarrow t=18[/tex]

Total number of trucks counted is 18.

Write an equation of the line passing through point P(4,0) that is parallel to the line -x + 2y = 12.

Answers

arallel lines have the same slope
-x+2y=12
2y=x+12
y=(1/2)x+6
the slope is 1/2
using the point-slope form of a line...
y-y1=m(x-x1) where m is the slope and (x1,y1) is (4,0)
y-0=(1/2)(x-4)
y=(1/2)x-2 is the equation of the line
check: 0=(1/2)(4)-2
0=2-2
0=0
Answer: y= 1/2x-2
___________________
Explanation:

-x+2y=12
2y=12+x
divide both sides by 2
y= 6+ x/2
as they are parallel, therefore, their slopes are equal
hence,
put P(4;0) in the equation to find y intercept( y=kx+b, there b is y intercept)
0= 1/2 * 4+ b
b=-2
hence,
our equation is
y=1/2x-2

When a number n is divided by 10000, the quotient is 1 and the remainder is 2011. The quotient and the remainder when n is divided by 2011 are respectively.

Answers

Answer:

[tex]Remainder = 1956[/tex]

[tex]Quotient = 5[/tex]

Step-by-step explanation:

Given

[tex]Dividend = n[/tex]

[tex]Divisor = 10000[/tex]

[tex]Quotient = 1[/tex]

[tex]Remainder = 2011[/tex]

Required

Determine the quotient and remainder when the divisor is 2011

First, we need to determine the value of n.

The relationship between the given parameters is:

[tex]Dividend = Quotient * Divisor + Remainder[/tex]

Substitute values in the above:

[tex]n = 1 * 10000 + 2011[/tex]

[tex]n = 10000 + 2011[/tex]

[tex]n =12011[/tex]

So, we divide 12011 by 2011 and record the quotient and divisor:

[tex]\frac{12011}{2011} =[/tex]

The integer division of 12011 and 2011 is 5.

The remainder is calculated using:

[tex]Dividend = Quotient * Divisor + Remainder[/tex]

Where

[tex]Dividend = 12011[/tex]

[tex]Quotient = 5[/tex]

[tex]Divisor = 2011[/tex]

So, Remainder =:

[tex]Remainder = 12011 - 2011* 5[/tex]

[tex]Remainder = 12011 - 10055[/tex]

[tex]Remainder = 1956[/tex]

Hence:

[tex]\frac{12011}{2011} = 5\ Remainder\ 1956[/tex]

What is the difference between ordering numbers, comparing numbers, and comparing amounts?

Answers

Answer:

different definitions

Step-by-step explanation:

ordering numbers can be seen as arranging the numbers by a certain characteristics. for example, you could order numbers from least to greatest

comparing numbers can be seen as looking into two or more numbers rather than the entire group of numbers. for example, if there were the numbers 1, 2, 3, 4, 5, 6, you could say that 2, 4, 6, are even numbers

comparing amounts could be determined by worth but not the numerical values. for example, you could have a gallon of milk and a quart of orange juice but just by the size of the container, a gallon of milk is bigger and holds more than a quart of orange juice

someone pls help and dont troll

Answers

Answer: A

Step-by-step explanation:

2x + 9 = 15

2x = 6

x = 3

2x+9 = -15

2x = -24

x = -12

2x+9=15 or 2x+9=-15

- Case 1: 2x+9=15. Then 2x=15-9=6. Thus, x=3.
- Case 2: 2x+9=-15. Then 2x=-15-9=-24. Thus x=-12.

Hence x=3 or x=-12.

FREE BRAINLY! What is the equation of the line perpendicular to the line y = -3 and passing through the point (2, -1)?

Answers

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

We want the equation of the line perpendicular to y=-3.

Notice that y=-3 is a horizontal line.

Therefore, in order to be perpendicular, our new equation must be vertical.

We know that it must pass through the point (2, -1).

Since it must be vertical, it must pass through the x-coordinate.

Therefore, our line must be:

[tex]x=2[/tex]

It passes through (2, -1) and is a vertical line, so it’s perpendicular to y=-3.
