Answer:

36 m

Step-by-step explanation:

15 + 15 + 3 + 3 = 36

Perimeter is the total length of the outside of the figure.

Answer: 36

Step-by-step explanation:

15+15+3+3=36

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.

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:

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°

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

Small --> 1/70

Big --> 1/30

Together --> 1/70 + 1/30 = 3/210 + 7/210 = 10/210 = 1/21

Answer:

40 minutes

Step-by-step explanation:

70 minutes - 30 minutes

Step-by-step explanation:

To find the y-intercept, you need to set the x-value to 0.

Step 1:  Find the y-int for the first equation

[tex]y = \frac{1}{2}x[/tex]

[tex]y = \frac{1}{2}(0)[/tex]

[tex]y = 0[/tex] ← y-int for first equation

Step 2:  Find the y-int for the second equation

[tex]y = 2 - x[/tex]

[tex]y = 2 - (0)[/tex]

[tex]y = 2[/tex] ← y-int for second equation

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].

3) [tex]x = 4[/tex]

4) [tex]x = \frac{5}{2}[/tex]

Step-by-step explanation:

-Calculations for every question:

[tex]\frac{2x}{2} = \frac{10}{2}[/tex]

[tex]x = 5[/tex]

2) [tex]\frac{1}{2}x + 6 = 10[/tex]

[tex]\frac{1}{2}x + 6 - 6 = 10 - 6[/tex]

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.

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.

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.
