If a line has a slope of 3, what is the slope of a line perpendicular to it?
Answer:
- [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex]
Here m = 3 , then
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{3}[/tex]
A light bulb consumes 3600 watt-hours per day. How many watt-hours does it consume in 4 days and 18 hours?
Answer:
17,100
Step-by-step explanation:
A light bulb consumes 3600 watts per day
Therefore the number of watts consumed in 4 days 18 hours can be calculated as follows
3600= 24 hours
x= 1 hour
= 3600/24
= 150 watts in an hour
3600×4
= 14,400
150×18
= 2,700
Total watts
= 14,400+2700
= 17,100
Hence the number if watss produced in 4 days 18 hours is 17,100 watts

JK, KL, and IJ are all tangent to o (not drawn to scale). JA = 8, AL = 11, and
CK = 10. Find the perimeter of AJKL.
Answer:
[tex]P = 58[/tex]
Step-by-step explanation:
The image if the circle and triangle can be found online
Given
[tex]JA = 8[/tex]
[tex]AL = 8[/tex]
[tex]CK = 10[/tex]
Required
The perimeter of JKL
Since the mid-points of the tangents are A, B and C respectively.
[tex]JK = JB + BK[/tex]
Where
[tex]JB = JA = 8[/tex]
[tex]BK = CK = 10[/tex]
So:
[tex]JK =8+10 =18[/tex]
[tex]JL = JA + AL[/tex]
[tex]JL = 8+11 = 19[/tex]
[tex]KL = CL + CK[/tex]
Where
[tex]CL =AL = 11[/tex]
So:
[tex]KL = 11+10 = 21[/tex]
So, the perimeter (P) is:
[tex]P = JK+ KL +JL[/tex]
[tex]P = 18 + 19 + 21[/tex]
[tex]P = 58[/tex]

Jeremy uses 2 feet 3 inches of board for each birdhouse he builds. How many inches of board does he need to make 6 birdhouses?
Answer:
134inches
Step-by-step explanation:
Convert 2feet to inches
1foot= 12 inches
2feet= 12x2inches
=24inches
24inches is to 1 birdhouse
24inches x 6 equals six birdhouses
134inches
Answer:
He will need 162 inches
Step-by-step explanation:
6×2ft is 12 feet. Convert ft into inches for every 1 foot you have 12 inches. A total of 144in. Now multiply 6×3in which equals 18in. Add 144+18=162

At Factory Y, a worker's wages for a 40-hour week is $200. She is paid 10% of her regular weekly wages for every hour that she works overtime. At the end of a certain week she received $380. Calculate the number of hours of overtime that she worked.
Answer:
She worked 18 hours of overtime.
Step-by-step explanation:
If she works 40 hours per week and gets $200, subtract $380 - $200 = $180.
If you multiply $180 by 0.1 (which is 10% converted to a decimal), you get 18 which is your final answer.

A rectangle is formed by placing two identical squares side by side. the area of the rectangle is 892 cm2. What is the perimeter of the square?
Answer:
288 cm^2
Step-by-step explanation:
If you have 2 congruent squares, side by side, the perimeter is 6*sidelength.
We divide 72 by 6 to find sidelength, and get 12.
We square 12 to find the area of a square, and get 144.
Multiply by 2 to find the area of the rectangle, and get 288 cm^2

A wooden frame is to be constructed in the form of an isosceles trapezoid, with diagonals acting as braces to strengthen the frame. The sides of the frame each measure 5.3 feet, and the longer base measure 12.7 feet. If the angles between the sides and the longer base each measure 68.4 degrees, find the length of one brace to the nearest tenth of a foot.
Answer:
11.8 ft
Step-by-step explanation:
Since the length of one side, l = 5.3 ft, the longer base b = 12.7 ft and the one brace, d form a triangle with angle between the longer base and side being the angle facing the brace is θ = 68.4°, we use the cosine rule to find the length of thee brace.
So d² = l² + b² -2lbcosθ
So, substituting the values of the variables into the equation, we have
d² = (5.3 ft)² + (12.7 ft)² -2(5.3)(12.7)cos68.4°
d² = 28.09 ft² + 161.29 ft² - 134.62(0.3681)
d² = 189.38 ft² - 49.56 ft²
d² = 139.82 ft²
taking square-root of both sides, we have
d = √139.82 ft²
d = 11.82 ft
d ≅ 11.8 ft to the nearest tenth of a foot.
