50 cm2 = length x height
50 divided by 2 is 25
50 cm2= 25 cm x25 cm
How do I find angle CAE?
========================================================
Explanation:
Angle DAB and angle ABC are congruent angles due to the parallel lines (note they are alternate interior angles).
So angle DAB = 47 since angle ABC = 47.
Let angle CAE be equal to x for now.
The three angles DAB, CAB, and CAE all add up and combine to form a straight angle which is 180 degrees.
We'll use this fact to find x
(angle DAB) + (angle CAB) + (angle CAE) = 180
(47) + (105) + (x) = 180
x + 152 = 180
x + 152-152 = 180-152 .... subtract 152 from both sides
x = 28
angle CAE = 28 degrees
The model shows the addition expression 18 + 12.
One expression that is equivalent to this sum is _____.
A. 3 + 6 + 4
B. 3 (6 + 4)
C. (3 + 6) 4
D. 3 (6) + 4

Solve the square root
Answer:
x = 14
Step-by-step explanation:
We need to solve the given expression.
[tex]\sqrt{x+2}+4=0[/tex]
Subtract 4 from both sides,
[tex]\sqrt{x+2}+4-4=-4\\\\\sqrt{x+2}=-4[/tex]
Squaring both sides,
[tex](\sqrt{x+2})^2=(-4)^2\\\\(x+2)=16\\\\x=16-2\\\\x=14[/tex]
So, the value of x is equal to 14.
Solve for x. Round all answers to the nearest tenth

A cone has a height of
11 inches and a volume
of 132TT in3. What is the radius
of the cone?
Answer:
A radius is the distance from the circle's middle to its perimeter, which is known as its circumference. The radius of a cone is the radius of its circular base. You can find a radius through its volume and height. Multiply the volume by 3.

Encontrar las coordenadas en el círculo trigonométrico para los segmentos de recta cuyo ángulo tienen un valor de α = 45°
a) (√3/2, 1/2)
b) (√2/2, 2/2)
c) 1,0
d) 0,1
The coordinates of E is (1/√2,1/√2). Furthermore, none of the alternatives provided are correct.
The question is in Spanish and the question doesn't have the correct option. The English translation is as follows.
Find the coordinates on the unit circle for the line segments whose angle has a value of α=45°.
What is a unit circle?A circle with a radius of 1 unit is called a unit circle.
How to solve the problem?The given line is making α=45° with the x-axis and intersects the unit circle at E. Make a perpendicular passing through then we get a right-triangle AEG (as shown in the below figure)
To find the coordinates of E we need to find the lengths EG and AG.
We know that in the right-triangle
AG=AEcos²45° and
EG=AEsin²45°
But AE=1 unit and cos45°=sin45°=(1/√2).
Hence, the coordinates of E are (1/√2,1/√2).

A loan for $4,000 is given at a 6% interest rate for 2 years. Find the simple interest owed on the loan.
Answer:
I = $ 480.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
then, solving our equation
I = 4000 × 0.06 × 2 = 480
I = $ 480.00
The simple interest accumulated
on a principal of $ 4,000.00
at a rate of 6% per year
for 2 years is $ 480.00.
2 triangles and 4 circles what is the simplest ratio of triangles to circles?
Answer:
2:4
or in simplest form, 1:2
Step-by-step explanation:
Answer:
2:4
Step-by-step explanation:
As the question said "what is the simplest ratio of triangles to circles?" . You have to write triangles : circles . But in the beginning of the question it said "2 triangles and 4 circles" so we have to use numbers instead of words. That why the answer is 2:4.

Is 1/4 greater than or less than 3/9
Answer: Less
Step-by-step explanation: Ok lets make them both have a common denominator. This is 36. So 1/4 is going to be 9/36 and 3/9 is going to be 12/36
Answer:
1/4 is less than 3/9.
Step-by-step explanation:
Take these fractions into decimal format.
1/4 = 0.25
3/9 = 0.33.
From this, 0.25 < 0.33
So, 1/4 < 3/9, or 1/4 is less than 3/9.
Becka draws two different quadrilaterals. Both quadrilaterals have two pairs of parallel lines. Only one quadrilateral has 4 right angles. What might the quadrilaterals be?
Answer:
Rectangle and Parallelogram
Step-by-step explanation:
Quadrilaterals are closed figures with four sides. Examples are: square, rectangle, parallelogram etc.
In the given question,
i. one of the parallelograms would be a rectangle since it has 4 right angles and two pairs of parallel lines.
ii. the other would be a parallelogram since it has two pairs of parallel lines and angles are not right angles.
The two quadrilaterals would be rectangle and parallelogram.
The average high temperature during the hottest month in Beijing, China, is 72°F. The average high temperature during the coldest month in Beijing is 18°F. The function 1 =27 cos( π/6(m-6)) +45, where m represents the number of months after January, models the temperature throughout the year in Beijing. During which monke in the year would the temperature reach 55°F?
- August
- September
- November
- December
(it'll be SEPTEMBER, i just couldn't find the answer for it anywhere else, so here ya gooo.)
Answer:
- September
Step-by-step explanation:
The temperature in Beijing, in m months after January, is given by the following equation:
[tex]T(m) = 27\cos{((\frac{\pi}{6})(m-6))} + 45[/tex]
In which m is the number of months after January.
During which month in the year would the temperature reach 55°F?
We have to find m for which: T(m) = 55. So
[tex]T(m) = 27\cos{((\frac{\pi}{6})(m-6))} + 45[/tex]
[tex]55 = 27\cos{((\frac{\pi}{6})(m-6))} + 45[/tex]
[tex]27\cos{((\frac{\pi}{6})(m-6))} = 10[/tex]
[tex]\cos{((\frac{\pi}{6})(m-6))} = \frac{10}{27}[/tex]
Now, we apply the inverse cosine, on both sides of the equation, to find the value of m.
[tex]\cos^{-1}{\cos{(\frac{\pi}{6})(m-6)}} = \cos^{-1}{\frac{10}{27}}[/tex]
Now, with the help of a calculator, in radians:
[tex]\frac{\pi}{6}(m-6) = 1.19[/tex]
[tex]\pi m - 6\pi = 6*1.19[/tex]
[tex]\pi m = 6*1.19 + 6 \pi[/tex]
[tex]m = \frac{6*1.19 + 6 \pi}{\pi}[/tex]
[tex]m = 8.27[/tex]
8.27 months after January, since 8.27 + 1 = 9.28, it happens during the month of September.
