When a kite is flying, the string makes an angle of 22° with the horizontal, and the string is 200m long. How high is the kite?
Answer: Check the picture below.
Make sure your calculator is in Degree mode.
the question "how long is the kite?" is not quite clear, i suppose it was asking how far it was from the ground (b) or horizontally (a). I calculated both, I hope this helps

The midpoint of AB is M(2, 0) If the coordinates of A are (-3, 3) what are the coordinates of B
Answer:
(7, -3)
Step-by-step explanation:
If M is the midpoint you can use the same translation from A to M as M to B.
The movement from A to M is 5 units up and 3 units left, or (x+5, y-3). If we do the same movement to point M (Which is (2) +5, (0) -3) we will get (7, -3).
Answer:
the coordinates of B is B(7,-3)
Step-by-step explanation:
Solution,
Here, M(2,0) is the midpoint of a line segment joining the points A(-3,3)
and B(a,b)
Let,
(x,y)=(2,0)
(x1,y1)=(-3,3)
(x2,y2)=(a,b)
Now,
Using midpoint formula
[tex]x=\frac{x_1+x_2}{2} ,y=\frac{y_1+y_2}{2} \\\\2=\frac{-3+a}{2} ,0=\frac{3+b}{2} \\\\[/tex][Cross multiply]

You load boxes onto an empty truck at a constant rate. After 3 hours, there are 100 boxes on the truck. How much longer do you work it you load a total of 120 boxes? You work hour(s) longer Justify your answer
Answer:
36 minutes
Step-by-step explanation:
100 boxes in 3 hours is a rate. It is how fast you are working in boxes per hour 100/3 boxesperhour.
But 3 doesn't go into 100 very neatly and its going to make all kinds of ugly fractions or decimals. But lets look at minutes. 3 hours is 3 × 60 minutes (bc there's 60 minutes in an hour) So you loaded 100 boxes in 180 minutes. That's 100/180 boxes per minute.
100/180 = 10/18
10/18 means 10 boxes in 18 minutes.
So times 2 on the top and the bottom gives you 20/36.
20/36 means 20 boxes in 36 minutes.
This is your answer. It will take 36 minutes to load 20 more boxes.

12. Tina hanged 20 lanterns at an equal distance apart on a string as shown below. The distance between the 1st lantern and the 5th lantern is 80 cm. Find the distance between the 1st and the last lantern.
an equal distance = arithmetic sequence
xn= a+d(n-1)⇒ x₁ = a
x₅ - x₁ = 80
x₁ + 4d - x₁ = 80
4d = 80
d = 20 cm
x₂₀ - x₁ = x
x₁ + 19d - x₁ = x
19d = x
19.20 = 380

Answer:
Constant of proportionality: [tex]\frac{1}{3}[/tex]
Equation: [tex]y=\frac{1}{3}x[/tex]
Step-by-step explanation:
The constant of proportionality is the ratio between y and x, according to the following formula
constant of proportionality = k = y/x
Take the given pairs and replace the data.
1.
[tex]k=\frac{\frac{2}{3}}{2}[/tex]
[tex]k = \frac{1}{3}[/tex]
2.
[tex]k = \frac{1}{3}[/tex]
3.
[tex]k=\frac{\frac{10}{3}}{10}[/tex]
[tex]k = \frac{1}{3}[/tex]
4.
[tex]k = \frac{4}{12}[/tex]
[tex]k = \frac{1}{3}[/tex]
As you can see, the constant is the same for all the pairs.
constant of proportionality = [tex]\frac{1}{3}[/tex]
Now, in order to know the equation make a graph of the given data.
The graph is in the picture
Since it is a line, use the equation of the line in point slope form
[tex]y- { y }_{ 1 } = m \left( x- { x }_{ 1 } \right)[/tex]
where (x1, y1) = any pair of the data
m = slope = constant of proportionality
Replace the data in the equation
[tex]y-1 = \dfrac{ 1 }{ 3 } \left( x-3 \right)[/tex]
Use the distributive property to multiply [tex]\frac{1}{3}[/tex] by x - 3
[tex]y-1=\frac{1}{3}x-1[/tex]
Add 1 to both sides
[tex]y = \dfrac{ 1 }{ 3 } x-1+1[/tex]
Add −1 and 1 to get 0
[tex]y=\frac{1}{3}x[/tex]
or
[tex]y=\frac{x}{3}[/tex]

Step-by-step explanation:
*We're focusing on 2 to the power of 3.
2^3 is represented as 2 x 2 x 2, 2 is being multiplied by itself 2 times.
When we multiply, we find the product of 8.
Therefore,

s = 12 - 4h
12 - 4h + 2h = 7

The figure shows a rectangle ABCD where the diagonals AC and BD intersect at E.
Given that BEC = 52°, find
(I) ADB
(ii) ACD
Answer:
(i) 64°
(ii) 26°
Step-by-step explanation:
Answer:
(i) m<ADB = 64°
(ii) m<ACD = 26°
Step-by-step explanation:
I use this to mean the measure of angle ADC: m<ADC
(i)
m<BEC = 52°
<DEA and <BEC are vertical angles, so they are congruent.
m<DEA = m<BEC = 52°
Polygon ABCD is a rectangle. When the diagonals, AC and BD, of a rectangle are drawn, 4 triangles are formed. Each two opposite triangles are congruent, and all 4 triangles are isosceles.
Triangle ADE is an isosceles triangle with congruent sides ED and EA. That makes opposite angles ADB and DAC congruent. Also the sum of the measures of the angles of a triangle is 180°.
m<ADB + m<DAC + m<DEA = 180°
m<ADB = m<DAC; m<DEA = 52°
2m<ADB + 52° = 180°
2m<ADB = 128°
m<ADB = 64°
(ii)
Angles DEC and BEC form a linear pair. That means the angles are supplementary, and the sum of their measures is 180°.
m<DEC + m<BEC = 180°
m<DEC + 52° = 180°
m<DEC = 128°
Triangle DEC is an isosceles triangle with congruent sides ED and EC. That makes opposite angles ACD and BDC congruent.
m<ACD + m<BDC + m<DEC = 180°
2m<ACD + 128° = 180°
2m<ACD = 52°
m<ACD = 26°

JOSHUA ORDERED A NEW PAIR OF NIKES ONLINE FOE $168 AND 2 HATS FOR $39 EACH HIS SHIPPING FEE IS 10% OF HIS TOTAL PURCHASE RICE HOW MUCH WILL JOSHUA PAY ALTOGETHER
Answer:
Joshua is paying a total of $270.60.
Step-by-step explanation:
Info that we have:
Pair of Nikes is $168.
2 hats for $78. (Not 39 because the question said $39 for each).
Shipping fee is 10% of total purchase.
We need to add up the cost.
168 + 78 = $246
Find how much is 10%.
10% of 246 = 24.6
Add the shipping fee to the total.
246 + 24.60 = 270.60
Answer:
Joshua is paying a total of $270.60.
Info that we have:
Pair of Nikes is $168.
2 hats for $78.

[tex]\text{On Applying componendo and dividendo, we get:-}[/tex]

[tex] \implies \: \frac{x + 1}{x - 1} = \frac{2( \sqrt[3]{m + 1)} }{2( \sqrt[3]{m - 1)} } \\ \\ \implies \frac{ x + 1}{x - 1} = \frac{ \sqrt[3]{m + 1} }{ \sqrt[3]{m - 1} } [/tex]
[tex] \text{On Cubing both sides, we get} \\ \frac{(x + 1) {}^{3} }{(x - 1) {}^{3} } = \frac{m + 1}{m - 1} [/tex]
