Answer:
23.5
Step-by-step explanation:
So this is a parallelogram so the area formlula is b*h=47? That's a no go. It is saying that if the base is 1/4th and the height is increasing by 2 so basically 1/4b*2h=1/2bh bh so it will be represented as 47 so 1/2*47=23.5

Answer:
214°
Step-by-step explanation:
The external angle (marked 34°) is equal to half the difference of the arcs ACB and AB.
34° = 1/2(ACB -AB)
Together, the two arcs form a complete circle of 360°, so we have ...
34° = 1/2(ACB -(360° -ACB)) = 1/2(2ACB -360°)
34° = ACB -180° . . . . . . . . . . . . simplify
180° +34° = ACB = 214° . . . . . add 180°
The measure of arc ACB is 214°.

In a right triangle, the side opposite angle φ has a length of 29.0 meters, the side adjacent to angle φ has a length of 49.5 meters, and the hypotenuse has a length of 57.4 meters. What is the value of cot(φ)?

1.707
0.586
1.160
The right triangle with sides 29m, 49.5m and 57.4 m has the value of cot φ as 1.707
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees.
Therefore, it has an opposite, adjacent and hypotenuse side depending on the angle.
oposite side = 29 m
adjacent side = 49.5 m
hypotenuse side = 57.4 m
Therefore,
cot φ = 1 / tan φ
Hence,
tan φ = opposite / adjacent
Therefore,
cot φ = adjacent / opposite
cot φ = 49.5 / 29
cot φ = 1.70689655172
cot φ = 1.707

order 130 in, 4 yd in 10 ft from greatest to least
Answer: 4 yd, 130 in, 10ft
Step-by-step explanation:
So first you turn everything into inches
130 inches is already in inches.
4 yards = 12 ft
1ft = 12 in
12 *12 = 144 in
so 4 yards is 144 inches
10 ft = 12*10
12*10 = 120
so 10ft is 120 inches
144 inches is the greatest and 120 inches is the least.
The answer needs to be in the original form.

The dues in a neighborhood increased from $24 per month to $30 per month. Find the percent of increase.
Answer:
25%
Step-by-step explanation:
Think about it like this: $24 multiplied by how much equals $30?
This in equation form would be [tex]24x=30[/tex]
To solve for x, divide both sides by 24: [tex]x=30/24[/tex] or [tex]x=5/4[/tex]
5/4 in percentage form would be 125%, so the dues increased by 25%
