Answer:
The distance, in feet, from the ground to the ladder is 12 feet.
Step-by-step explanation:
To answer this question, we must use the Pythagorean Theorem- a^2+b^2=c^2. C is the hypotenuse, and a and b are legs.
We have: 5^2+b^2=13^2
Simplifying: 25+b^2=169
Subtracting 25 from both sides: b^2=144
B=12.
What is the area of a sector of a circle with of 5 meters and subtended by a central angle of 180 degrees. Around to two places
Answer:
[tex]A=39.26\ m^2[/tex]
Step-by-step explanation:
Given that,
The radius of a circle, r = 5 m
The central angle is 180 degrees
We need to find the area of a sector of a circle.
The formula for the area of sector of a circle is given by :
[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{180}{360}\times \pi \times (5)^2\\\\A=39.26\ m^2[/tex]
So, the area of the sector of a circle is [tex]39.26\ m^2[/tex].
x + y = 5.5
x + 2y = 7
solve the equation using elmeniation
Answer:
y=1.5
x=4
Step-by-step explanation:
x=5.5-y
x+2y=7
(5.5-y)+2y=7
5.5-y+2y=7
y=7-5.5
y=1.5
x+1.5=5.5
x=5.5-1.5
x=4

Explain and compare sequences that have first differences, second differences, and third differences and the type of relationship they satisfy.
Answer:
Please find the answer in the explanation
Step-by-step explanation:
Explain and compare sequences that have first differences, second differences, and third differences and the type of relationship they satisfy
When a sequence has first difference, that mean it has the same difference between the number through out. Such a sequence is Linear. Examples of such are :
1, 3, 5, 7, 9, ........
2, 5, 8, 11, ...........
When a sequence has second difference, that mean it does not have the same difference between the number through out. It has the same sequence at the second order.
Such a sequence is quadratic. Example of such is :
1, 3, 6, 10, 15, .........
When a sequence has third difference, that means it does not have the same difference between the number through out in the first and second order but in the third order. Such a sequence is exponential. Example of such is :
1, 2, 5, 10, 17, .........

Answer: 8.4
Step-by-step explanation:
You would convert 25 into a decimal 0.25 and then you would multiply it by 34 which would get you 8.4 hope this helped brutherr
Answer:
8.5
Step-by-step explanation:
Break the number up in 4ths. Like a dollar. One fourth is equal to 25%, divide 34 by 4 and you get 8.5. Its the same way as doing 25% of 34! To check your work do 8.5 x 4 and you get 34!

The expression on the left side of an equation is shown below.
-6x+6=0
If the equation has an infinite number of solutions, which expression can be written in the box on the othe
the equation?
0-6
1
-6x
o - 6x+6
Answer:
(x=1) - Below
0-6 = 6
1
(-6x) = -6
(0 - (6x))+6 = 12
Step-by-step explanation:
Step 1: Subtract 6 from both sides.
−6x+6−6=0−6
−6x=−6
Step 2: Divide both sides by -6.
−6x/−6 =− 6/−6
Step 3: x = 1

Answer:
he spent $68 without the fees and $32 on fees
Step-by-step explanation:
Jordan went to lunch and spent $32.00, without tax. He left an 18% tip for the waitress. What was the
total of the lunch, without tax?
Money spent by Jordan on his lunch = $32
Tips he left for the waitress :
= 18% of the money spent on his lunch
[tex]= 18\% \: of \: \: 32 [/tex]
[tex] = \frac{18}{100} \times 32[/tex]
[tex] = \frac{576}{100} [/tex]
[tex] =$ 5.76[/tex]
Thus, the tips he left for the waitress = $5.76
Total money he spent along with the tips :
[tex] = 32.00 + 5.76[/tex]
[tex] = $ 37.76[/tex]
Therefore, the total of the lunch was = $37.76
