C. Since it’s a maximum number. It’s less then or equal to symbol. Because you spent money. You subtract from d.

So the answer is C

The three inside angles (A,B and C) of a right angled triangle are in the ratio 7:18:11

Anastasy [175]

This is overdetermined. Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:

Answer: A=35°, C=90°, B=55°

We can do it the way they like.

7+18+11 =36

so to get 180 degrees we need to scale the ratio elements by a factor of 5.

7:18:11=35:90:55

A is the smallest. We see C is indeed a right angle and B is complementary to A.

In a series RL circuit, ET = 120 V, R = 40 Ω, and XL = 30 Ω. How much is EL?

dezoksy [38]

Firstly, we will draw

RL series circuit

ET = 120 V, R = 40 Ω, and XL = 30 Ω

Firstly, we will find current

$I=\frac{E_T}{R+jX_L}$

now, we can plug values

and we get

$I=\frac{120}{40+j30}$

now, we can find voltage across L

$E_L=IjX_L$

so, we get

$E_L=\frac{120}{40+j30}(j30)$

now, we can find absolute value

$|E_L|=120\frac{30}{\sqrt{40^2+30^2} }$

$|E_L|=120\frac{30}{ 50 }$

$|E_L|=120\frac{3}{ 5 }$

$|E_L|=72V$ ...............Answer

Davy walks around a circular lake that has a diameter of 22 yards. Which best describes how far he walks, if he walks around the

kicyunya [14]

To find the circumference of the circle you need to do dπ. 22×π is 22π. That equals approximately 69.12. Since he walks around it 5 times, 69.12×5 is 345.6 yards.

Select the correct answer from each drop-down menu. The general form of the equation of a circle is 7x2 + 7y2 − 28x + 42y − 35 =

nignag [31]

The general form of the equation of a circle is,

x² + y² + Dx + Ey + F = 0, where D, E, F are constants.

The given equation is 7x² + 7y² − 28x + 42y − 35 = 0. So, to convert this equation into a general form we just need to get rid of the leading coefficient 7.

Hence, divide both sides of the equation by 7. So,

$\frac{7x^2+ 7y^2-28x + 42y-35}{7} =0$

x² + y² − 4x + 6y − 5=0.

So, the general form of the equation is x² + y² − 4x + 6y − 5=0.
