Answer:
J- 6/4 = h/20
Step-by-step explanation:
J- 6/4 = h/20
6 is similar to h and 4 to 20.
Cross multiply
6 (20) = 4h
120/4 = 4h/4
30 = h

Answer:
1
Step-by-step explanation:
The sum of probability of two complementary events is always equal to 1. This happens because the probability of a complementary event is always determined by deducting the probability of a given event from 1.

Here's the solution,
the opposite angles of parallelogram are equal, so, Angle G = Angle E
=》3x + 11 = 5x - 9
=》5x - 3x = 11 + 9
=》2x = 20
=》x = 10
value of x = 10
now, Angle G = 5x - 9
=》(5 × 10) - 9
=》50 - 9
=》41°
Angle G and Angle F are supplementary, so
=》 41° + Angle F = 180°
=》Angle F = 180° - 41°
=》Angle F = 139°

Work out
x
,
Answer:
x = 55degrees
Step-by-step explanation:
Find the diagram attached
Since triangle DBC is isosceles, the bse angles are equal. Let the base angles be y, hence;
y + y + <BDC = 180
2y + 50 = 180
2y - 180 - 50
2y = 130
y = 65
From triangle ADC;
x + < ADB + <BDC + <DCB = 180
x + 10 + 50 + 65 = 180
x+ 125 = 180
x = 180 - 125
x = 55degrees

The cylinder is 20cm high and radius of its circular face is 3cm What is the total perimeter and area of the whole net?
Answer: [tex]52\ cm,\ 176.55\ cm^2[/tex]
Step-by-step explanation:
Given
The cylinder is 20 cm high
The radius of the cylinder is [tex]r=3\ cm[/tex]
The total area of the figure is the sum of the rectangle and two circles
[tex]\Rightarrow \text{Perimeter P=}2[h+2r]\\\Rightarrow P=2[20+6]\\\Rightarrow P=52\ cm[/tex]
The total area of the figure is
[tex]\Rightarrow \text{Area A=}h\times 2r+2\pi r^2\\\Rightarrow A=20\times 6+2\times \pi \times 3^2\\\Rightarrow A=120+18\pi\\\Rightarrow A=176.55\ cm^2[/tex]

In order to complete a large job, 1000 workers were hired, just enough to complete the job on schedule. All the workers stayed on the job while the first quarter of the work was done, so the first quarter of the work was completed on schedule. Then 100 workers were laid off, so the second quarter of the work was completed behind schedule. Then an additional 100 workers were laid off, so the third quarter of the work was completed still further behind schedule. Given that all workers work at the same rate, what is the minimum number of additional workers, beyond the 800 workers still on the job at the end of the third quarter, that must be hired after three-quarters of the work has been completed so that the entire project can be completed on schedule or before?

A clothes shop has some special offers.
T-shirts are buy one get one free and jumpers are 3 for 2.
The normal price of a T-shirt is £4.80 and the normal price of a jumper is £14.60.
How much does it cost to get 5 jumpers and 4 T-shirts using this offer as appropriate?
Answer:
The cost of 5 jumpers will be £ 58.40 (one more can be taken for free), the cost of 4 T shirts will be £ 9.60, and the total cost of the purchase will be £ 68.
Step-by-step explanation:
Since a clothes shop has some special offers, for which T-shirts are buy one get one free and jumpers are 3 for 2, and the normal price of a T-shirt is £ 4.80 and the normal price of a jumper is £ 14.60, to determine how much does it cost to get 5 jumpers and 4 T-shirts using this offer as appropriate, the following calculation must be performed:
4 T shirts = 2 + 2
4.80 x 2 = 9.60
5 jumpers = 2 (+1) + 2
4 x 14.60 = 58.40
Therefore, the cost of 5 jumpers will be £ 58.40 (one more can be taken for free), the cost of 4 T shirts will be £ 9.60, and the total cost of the purchase will be £ 68.

Branson Creek Middle School has decided to make fitness a key message to their students in the upcoming school year. As a result, they will be participating in a national fitness program. To participate, they must randomly select 15 students in the 5th grade and record their exercise time each day. The data (in minutes) are shown.
85, 80, 76, 78, 82, 88, 80, 80, 110, 85, 85, 82, 83, 88, 76
Describe the distribution of the data.
Determine the median and mean of the data.
Which measure better represents a typical value in the data set? Explain.
Answer:
data from minimum to maximum :
76 76 78 80 80 80 82 82 83 85 85 85 88 88 110
n= 15 , so the median is X8 = 82 minutes
mean =
(76+76+78+80+80+ 80 +82+ 82+ 83+ 85+ 85+ 85 +88 +88+ 110) / 15 = (1,258)/15 = 83.87 minutes
in order to get higher standard its better use mean as a typical value.

In ΔKLM, k = 530 cm, l = 200 cm and m=500 cm. Find the measure of ∠L to the nearest degree.
The measure of ∠L to the nearest degree is 22° (approx).
What are the laws of cosines?The square of any one side of a triangle is equal to the difference between the sum of the squares of the other two sides and double the product of the other sides and the cosine angle contained between them, according to the law of cosine.
Given ΔKLM,
k = 530 cm, l = 200 cm, and m = 500 cm,
to find the angle L,
we can calculate it by cosine law,
according to the cosine law,
l² = k² + m² - 2kmcosL
cos(L) = (k² + m² - l²)/2km
2km = 2*530*500
2km = 5,30,000
k² + m² - l² = (530)² + (500)² - (200)²
k² + m² - l² = 4,90,900
substitute the values
cos(L) = (k² + m² - l²)/2km
cos(L) = 4,90,900/5,30,000
cos(L) = 0.92622
L = cos⁻¹(0.92622)
L = 22.1459°
L = 22° (approx)
Hence the measure of angle L is 22° (approx).

solve for x in each exponential equation. Round off answers to four decimal places.
Answer:
0.6875
Step-by-step explanation:
24.5 = 3.2⁴ˣ
To get the exponent out of its exponent form, we need to take the ln of both sides:
ln(24.5) = 4x · ln(3.2) - divide both sides by ln(3.2)
[tex]\frac{ln(24.5)}{ln(3.2)}[/tex] = 4x - divide both sides by 4
x = 0.6875
2 workers are working together. They finish their work in 12 hours. if the ratio of their work together is 3:2 how long did each of them work
Answer:
7.2 and 4.8hrs
Step-by-step explanation:
Given the ratio it took them to finish work as 3:2
Total ratio = 3+2 = 5
For the larger ratio;
3/5 *12
= 36/5
= 7.2hrs
For the shorter ratio;
2/5 * 12
= 24/5
= 4.8hrs
Hence the first worker worked for 7.2hrs while the second was 4.8hrs
The kite shown has a width of 24 inches and a total height of 42 inches. What is the total area of the kite without the tail? Show your work for full
credit.
Answer:
504 in²
Step-by-step explanation:
The area of a kite is given by :
(a * b) / 2
Where a and b are the width and height of the kite :
Width = 24 inches ; height = 42 inches
Hence,
Area of kite = (24 * 42) / 2
Area of kite = 24 * 21
Area of kite = 504 in²

slope = rise/run
rise = -3 ... move down 3 units
run = 4 .... move to the right 4 units
============================================
Work Shown:
m = slope
m = rise/run
m = (change in y)/(change in x)
m = (y2-y1)/(x2-x1)
m = (-17-(-2))/(24-4)
m = (-17+2)/(24-4)
m = -15/20
m = -3/4 is the slope
----------------
It basically means "move down 3 units, and move to the right 4 units"
So, slope = rise/run = -3/4
rise = -3 = move down 3 units
run = 4 = move to the right 4
You could express the slope as a decimal, and that would be -3/4 = -0.75, but you lose the rise and run values. So I recommend you keep the fraction.
Another problem with decimals is that sometimes we could have approximations that aren't exact. For example, if the slope was 2/3, then that approximates to 0.667 which may cause rounding errors down the line. Though I should point out that decimals do have their advantages in some cases.

Recall the equation for a circle with center ( h , k ) and radius r . At what point in the first quadrant does the line with equation y = 2.5 x + 4 intersect the circle with radius 5 and center (0, 4)?
Answer: The required point = (1.857,8.643)
Step-by-step explanation:
Equation of circle with center (h,k) and radius r: [tex](x-h)^2+(y-k)^2=r^2[/tex]
Given: Radius = 5 , center = (0,4)
Eqation of circle: [tex](x-0)^2+(y-4)^2=5^2[/tex]
[tex]x^2+(y-4)^2=25[/tex]
[tex]x^2+(2.5x+4-4)^2=25[/tex] [Using equation y = 2.5 x + 4 ]
[tex]x^2+(2.5x)^2=25[/tex]
[tex]x^2+6.25x^2=25[/tex]
[tex]7.25x^2=25[/tex]
[tex]x^2=3.44827586207[/tex]
[tex]x=1.857[/tex]
[tex]y= 2.5(1.857)+4[/tex]
[tex]=8.6425[/tex]
Hence, the required point = (1.857,8.643)
