Math problem: If the dimensions of a triangle are two times bigger, how does the area of the triangle change? (Hint: Draw this)
Answer:
The equation for area of a triangle is height multiplied by the base length, divided by 2. So, if the height is 2, and the base is 4, then you multiply the two together, making 8, and then divide it by 2, making the final area 4. So if the dimensions are doubled, then the equation would be 4 times 8 divided by 2. Which is 16. If we do this again with 16 times 8, we will get 128, which when divided by two is 64. This is 4 times 16, just as 16 is 4 times the original answer 4. This means that every time you double the dimensions you will get the original answer multiplied by 4.

1.8
Can anyone help me ples?
Answer:
3.4
Step-by-step explanation:
Answer:
3.4
Step-by-step explanation:
Since we have given that
Number of multiple choice question = 4
Number of true false questions = 2
Number of points for each multiple choice question = 3
Number of points for each true false question = 1
Number of choices in multiple choice = 5
Probability of getting correct answer in multiple choice question = 1/5
Probability of getting correct answer in true false question = 1/2
answer would be 17/5 which is equal to 3.4

Which is the parametric form of the polar equation r=-4 theta?
A. x=-4 cos theta, y=-4 sin theta
B. x=-4 theta cos theta, y=-4 theta sin theta
C. x=-theta cos theta, y=-theta cos theta
Answer: Option B.
Step-by-step explanation:
we have that r = 4*θ
(you writted a negative equation, but we can never have a negative radius)
We also have that:
r = √(x^2 + y^2) = 4*θ
We can use the relationship cos(x)^2 + sin(x)^2 = 1
and write X = A*cos(θ) and Y = A*sin(θ)
and now we have:
r = √( (A*cos(θ))^2 + (A*sin(θ))^2) = √(A)^2 = 4*θ
So the correct option is:
x = 4*θ*cos(θ) or -4*θ*cos(θ)
y = 4*θ*sin(θ) or -4*θ*cos(θ)
(We can have the positive or negative options because we are squaring the term, so the sign does not matter)
The correct option then is B
Answer:
C) x = -4θcosθ and y = -4θsinθ

Answer: x = 12, y = [tex]12\sqrt{3}[/tex]
Step-by-step explanation:
A 30-60-90 triangle has sides whose lengths are related. (shown in the diagram attached) The longest side, the hypotenuse (opposite the right angle) represents 2x. The shortest side is x, and the last side is [tex]x\sqrt{3}[/tex].
We know the longest side = 24 = 2x.
If the shortest side is x, that means that the shortest side = the longest side DIVIDED by 2. Therefore, shortest side = x = 24/2 = 12 .
The last side is y and equals x\sqrt{3} . We now know that x = 12. Hence, y = [tex]12\sqrt{3}[/tex].
What is the measure of angle DAE?
Answer:
DAE=134-89=45
Step-by-step explanation:
SINCE BAF and CAE are opposite angles they are equal so
BAF=CAD+DAE
134=89+DAE
DAE=134-89=45
The measure of angle DAE is 45 degrees.
What is vertically opposite angle?when two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles.
According to the given question
m∠BAF = 134 degrees
and, m∠CAD = 89 degrees
Since, ∠CAE and ∠BAF are vertically opposite angles.
Therefore, m∠CAE = m∠BAF = 134 degrees
Now,
m∠CAE = m∠CAD + m∠DAE
⇒ m∠BAF = 89 + m∠DAE
⇒ 134 = 89 + m∠DAE
⇒ m∠DAE = 134 - 89
⇒ m∠DAE = 45 degrees
Hence, the measure of angle DAE is 45 degrees.

The supplementary angle to 97 is 83, so the lower right angle is 83 degrees.
We see that the upper left angle is 83 degrees and because these alternate interior angles are equal, the lines are parallel.
Answer:
AB is parallel to CD.
Step-by-step explanation:
The angle of inclination of AB and CD to the transversal are equal and of the same position.
The angle 97° of CD is corresponding to the same of AB

Answer:
1/10
Step-by-step explanation:
1/5÷2/1=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
1/5×1/2=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
1×1 /5×2=1/10
This fraction cannot be reduced.
Therefore:
1/5×1/2=1/10
On the diagram i need to fond the following measures of angles. Please help quickly!
Answer:
62° and 54°
Step-by-step explanation:
The exterior angle of a triangle is equal to the 2 opposite interior angles.
116° is an exterior angle of the triangle, thus
2x + 4 + 3x - 13 = 116, that is
5x - 9 = 116 ( add 9 to both sides )
5x = 125 ( divide both sides by 5 )
x = 25
Thus
∠ A = 3x - 13 = 3(25) - 13 = 75 - 13 = 62°
∠ B = 2x + 4 = 2(25) + 4 = 50 + 4 = 54°

The length of the Earth’s equator is about 40,000 km, and the Earth’s diameter is 8/25 the length of the equator. What is the diameter of the Earth?
Answer:
See Below:
Step-by-step explanation:
40,000*8/25= the diameter, because the diameter is 8/25 of the equator which is 40000
Diameter= 40,000*8/25
Diameter= 12,800 km
Answer:
12,800 km
Step-by-step explanation:
Since the length of the Earth's equator is 40,000 km and the diameter is 8/25 the length of the equator, indicates that you would multiply 40,000 by 8/25, which gives you a product of 12,800, or, the diameter of the Earth which is 12,800 km.
