Hello!

A pair of angles whose sum is 90° are called Complementary Angles. The answer is Complementary because Complementary Angles are angles that make a sum of 90°. Supplementary Angle are angles whose sum is 180° and Adjacent Angles are angles that have a common side or common vertex.

I hope this helps!

Answer:

B) Complementary angles

Step-by-step explanation:

A pair of angles whose sum is 90 degrees are respectively known as complementary angles; this means that their individual angle measures cannot be more than 90, so they are acute angles.  Perhaps the measure of complementary angles are 45 + 45 = 90.  Regardless, I hope this meets your expectations!

5x/2/11 = 3/1/5 please solve and write as a fraction in lowest terms
Marrrta [24]

Cross-Multiply

(5x/2)*(5)=(3/1)*(11)

12.5x=33

Divide both sides by 12.5

12.5x/12.5=33/12.5

x=2.64


I hope that's help ! Please don't forget to write it as a fraction in lowest terms. I am totally don't remember . Good night .

Using Pythagorean, a^2 + b^2 = c^2
16 +x^2 = 36.69
Then subtract the 16 from 36.69, which is 23.69
And finally take the square root of that, giving you 4.87

Answer:

c) The growth factor per days is 1.08

e) The growth factor per hour is 1.08^{1/24}

Step-by-step explanation:

Given the following data;

P(d) = 10 * 1.08^{d} in thousands.

a. To find the number of insects on day 1;

Day, d = 1

P(d) = 10 * 1.08^{d} ......equation 1

Substituting into the formula, we have;

P(1) = 10 * 1.08^{1}

P(1) = 10 * 1.08

P(1) = 10.08

Therefore, option (a) and (b) are incorrect.

c. To find the growth factor per day;

An exponential function is given by the formula;

y = mg^{x} .....equation 2

Where;

g is the growth factor of a population.

Comparing eqn 2 with eqn 1;

g = 1.08

Therefore, option (c) is correct.

e. To find growth factor per hour;

From equation 1 above;

P(1) = 10 * 1.08^{\frac {1}{2}}

Therefore, option e is correct.

-10-5y=-7y solve for y
scoray [572]
-10=-2y By adding 5y to Both sides of the equation

Divide both sides by -2.

-10 divided by -2 equals positive five. A negative divided by a negative equals a positive.

5=y
