Nomkhosi wants to start a vegetable garden. The garden will have a
rectangular shape, and will be 8 m long and 3 m wide. She wants to
put a fence around the garden. On each corner a metal post must be
planted, and along the sides, a thin metal post (a “dropper") must be
inserted every metre. Two posts, similar to the corner posts, must be
planted 1 m apart along one length to allow for a gate. Two horizontal
steel wires will be stretched around the camp, except at the gate.
Chicken wire fencing is to be attached to these two wires.

[tex](cos^{2} x-sin^{2}x)^{2} -sin4x+sin^{2}2x=0[/tex]
Answer:
x=22.5°
Step-by-step explanation:
(cos²x-sin²x)-sin4x+sin²2x=0
or, (cos2x)²-sin4x+sin²2x=0
or, cos²2x+sin²2x-sin4x=0
or, 1-sin4x=0
or, sin4x=1
or, 4x=90°
or, x=90°/4
or, x=22.5°

Answer:
2/3
Step-by-step explanation:
Let x represent the fraction of Cheryl's income she spent in September. Then 1-x is the fraction she saved.
In October, her spending increased by 0.2x, and her savings decreased by 0.4(1 -x). Since Cheryl spends or saves all of her income, these two change amounts must be equal:
0.2x = 0.4(1 -x)
x = 2(1 -x) . . . . . . multiply by 5 to clear fractions
x = 2 -2x . . . . . . eliminate parentheses
3x = 2 . . . . . . . . add 2x
x = 2/3 . . . . . . divide by 3
Cheryl spent 2/3 of her income in September.

ED = 32 ft
EC = 32 ft
DC = 28 ft
AC = 28 ft
BC = 32 ft
Answer:
AB = 32 ft
Step-by-step explanation:
If you rotate Triangle ECD 180 degrees clockwise, you will see that the sides line up perfectly with Triangle BCA, meaning that ED = AB and ED = 32 (transitive property of equality) so AB must also equal 32.

A desk drawer contains 5 red pens, 6 blue pens, 3 black pens, 24 silver paper clips, and 16 white paper clips. If you select a pen and
a paper clip at random, what is the probability that you select a black pen and a white paper clip? Round to the nearest tenth of a
percent
O A. 11.72%
B. 12.12%
C. 9.9%
O D. 8.6%
Answer:
Step-by-step explanation:
Probability of black pens = 3/14
Probability of white paper clips = 16/40
to find the probability of black pen and white paper clip we have to multiply these two probability.
3/14 x 16/40 = 48/560 = 8.6

Answer:
4050 cubic feet
Step-by-step explanation:
We would break this figure down into the square pyramid on the top and the cube on the bottom.
Volume of the cube:
l*w*h
= 15*15*15
= 3375.
Volume of the square pyramid:
a^2*(h/3)
= 15^2*(9/3)
= 225*3
= 675
Now we add the two to get the final answer:
3375+675=4050
The figure is 4050 cubic feet.
I hope this helped! :D
Answer:
Step-by-step explanation:
Cube:
Volume = length x width x height
V = 15 * 15 * 15
(Simplified version): 15³
V = 3,375ft³
Triangle:
Volume = 1/2 * base * height * length
V = 1/2 * 15 * 9 * 15
V = 1,012ft³
Add them both up to get our answer
3,375ft³ + 1,102ft³
4,477ft³
Therefore the volume of the figure is 4,477ft³

53/12 is the right answer.Steps:
1 2/3 + 2 3/4 can also be written as...
5/3 + 11/4
The LCD is 12 so we make both fractions have a denominator of 12.
That gives us 20/12+33/12
Now you can add the numerators (but leave the denominator the same)
That gives us 53/12, but our simplified version would give us 4 5/12 as our final answer.

Answer:
53
Step-by-step explanation
8 - 8/2 (this is a fraction) is also known as
8-4 because 8 divided by 2 is 4
so 8-4 = 4
next 4 + 7^2
why is the 2 in the air????
so that's called an exponent, in this case the two means 7 x 7, it is multiplying by itself, thats the essence of exponents. I can do this for exponent 3,4,5,6,7 and so forth. Anyways, 7^2 or 7x7=49
Knowing this its now 4+49= 53

Step-by-step explanation:
[tex]acceleration = \frac{velocity}{time} \\ = \frac{15ms ^{ - 1} }{20s} \\ = \frac{3}{4} ms ^{ - 2} \\ = 0.75 {ms}^{ - 2} [/tex]

[tex]\bf \large \implies \: Acceleration \: = \: \cancel\frac{15 \: \small \: m /s }{20 \: s} \: = \: \frac{3}{4} \: m /s ^{ - 1} \\ [/tex]
[tex]\bf \large \implies \: Acceleration \: = \: \cancel\frac{3}{4} \:m /s ^{ - 1} \: = \: 0.75 \: \: m /s ^{ - 1} \\ [/tex]

Please help me to solve this problem of ordered pairs. The value of x and y should be find.
Answer:
x=y=-2
Step-by-step explanation:
Comparing these ordered pairs, we will get
4^(1/x)=1/2 and 9^(1/y)=1/3
x=-2 and y=-2
Answer:
x = y = - 2
Step-by-step explanation:
Using the rule of radicals/ exponents
[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{a^{m} }[/tex] , [tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex] , [tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
Given
[tex]\sqrt[x]{4}[/tex] = [tex]\frac{1}{2}[/tex] , then
[tex]\sqrt[x]{2^{2} }[/tex] = [tex]\frac{1}{2}[/tex]
[tex]2^{\frac{2}{x} }[/tex] = [tex]2^{-1}[/tex]
Since the bases on both sides are equal, both 2 , then equate exponents
[tex]\frac{2}{x}[/tex] = - 1 ( multiply both sides by x )
2 = - x , that is
x = - 2
Similarly
[tex]\sqrt[y]{9}[/tex] = [tex]\frac{1}{3}[/tex] , then
[tex]\sqrt[y]{3^{2} }[/tex] = [tex]\frac{1}{3}[/tex]
[tex]3^{\frac{2}{y} }[/tex] = [tex]3^{-1}[/tex]
Equating the exponents gives
[tex]\frac{2}{y}[/tex] = - 1 ⇒ - y = 2 ⇒ y = - 2

Answer:
1,000
Step-by-step explanation:
First, there are 10,000 cents in $100.
So divide 10,000 by 10. (because 1 pencil is 10 cents)

2x = 5x - 10 is equivalent to -3x = -10.
True or false
Answer:
True
Step-by-step explanation:
2x = 5x - 10
Subtract 5x from each side
2x-5x = 5x-10-5x
-3x = -10
Answer:
True
Step-by-step explanation:
Given
2x = 5x - 10 ( subtract 5x from both sides )
- 3x = - 10 ← equivalent → True
what is the equation of the line written in general form?
Answer:
option 2 or y + x -2 = 0
Step-by-step explanation:
Given a line on a graph, it is easiest to start with point-slope form.
y = mx + b
where m is the slope (rise/run) and b is the y-axis intercept.
From the plot m = -2/2 = -1 and b = 2 SO
y = mx + b
y = -x + 2
Then the general form is
y + x -2 = 0
