What is the area of the figure below?
Use 3.14 for it.
fi6 cm
7 cm
A 42 cm
B 61.2 cm?
C 80.5 cm?
D 118.9 cm?
Answers
Answer:
option B
Step-by-step explanation:
The figure is combination of parallelogram and semi- circle. So,
area = area of parallelogram + area of semi-circle
[tex]Area \ of \ parallelogram = base \times height = 7 \times 6 = 42 cm^2\\\\Area \ of \ semi-circle = \frac{1}{2} \pi r^2 = \frac{1}{2} \times 3.14 \times 3.5^2 = 19.2cm^2\\\\Therefore \ Area = 42 + 19.23 = 61.2cm^2[/tex]

Given that ∠A=∠B, ∠A= 55 and ∠B=5x+10
We need to prove x=9
The given statements and reasons are given as below
∠A≅∠B (By given)
∠A=∠B (Congruency)
m∠A=55 (By given)
55=m∠B (Substitution)
m∠B=5x+10 (Given)
55=5x+10(Substitution)

If sin 0= 4/5 in quadrant II, what is cose? A. - 3/5 B. 3/5 C. - 3/4 D. 3/4
Answers
Answer:
A
Step-by-step explanation:
Given
sinθ = [tex]\frac{4}{5}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]
This is a 3- 4- 5 triangle
with opposite = 4, adjacent = 3 and hypotenuse = 5
Since θ is in second quadrant then cosθ < 0
cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = - [tex]\frac{3}{5}[/tex] → A
A question on my test:
Solve each equation over the interval [0°, 360°). If a decimal approximation is necessary, round to four decimal places. cos 2x -cos x-2 = 0
Answers
Answer:
180degrees
Step-by-step explanation:
Given the expression cos^2x - cos x - 2 = 0
Let P = cos x
P^2 - P - 2 = 0
Factorize
P^2 - 2P + P - 2 =0
P(P-2)+1(P-2) = 0
P-2 = 0 and P + 1 = 0
P = 2 and P = -1
Since P = cos x
cos x = -1
x = arccos(-1)
x = 180degrees
Hence the require angle is 180degrees

Explanation:
There are 5 gold and 350 total. That forms the fraction 5/350 which fully reduces to 1/70 after you divide both parts by the GCF = 5
A = 5, B = 350
A/GCF = 5/5 = 1 in the numerator of the final answerB/GCF = 350/5 = 70 in the denominator of the final answerThe fraction 1/70 can be thought of like saying "There's 1 gold coins in 70 coins total" or "there's 1 gold coin for every 70 coins".
Then we could scale up like so
1 gold : 70 total2 gold : 140 total3 gold : 210 total4 gold : 280 total5 gold : 350 totalLines a and b are parallel. What is the measure of angle b? Enter your answer in the box. 25 point question btw

The sound of a jet engine of a skyhawk jetfighter is 70000 times louder than the sound of a lawnmower if the lawnmower has the loudness of 88db then what is the loudness of the jet engine rounded to the 1DP
Answers
Answer: 6,160,000 db
Step-by-step explanation:
The sound of a jet engine is 70,000 times louder than that of a lawn mower.
Since we know the sound of a lawnmower, we can multiply that by 70,000 to find the sound of a jet engine:
= Sound of lawnmower * 70,000
= 88 * 70,000
= 6,160,000 db

Find the area of the composite figure.
Answers
Answer:
Area of composite figure = 623.25 cm²
Step-by-step explanation:
Given:
Equal side of triangle = 39 cm
Diameter of semi-circle = 30 cm
Base of triangle = 30 cm
Find;
Area of composite figure
Computation:
Radius of triangle = 30 / 2
Radius of triangle = 15 cm
Height of triangle = √39² - 15²
Height of triangle = √1,521 - 225
Height of triangle = 36 cm
Area of composite figure = Area of semi-circle + Area of triangle
Area of composite figure = [πr² / 2] + [(1/2)(b)(h)]
Area of composite figure = [(3.14)(15)² / 2] + [(1/2)(15)(36)]
Area of composite figure = [(3.14)(225) / 2] + [(15)(18)]
Area of composite figure = [706.5 / 2] + [270]
Area of composite figure = 353.25 + 270
Area of composite figure = 623.25 cm²
