A and B are complementary angles. If m_A = (6x + 29) and m
Liono4ka [1.6K]

Answer:

m∠A=77°

Step-by-step explanation:

Complementary angles are a pair of angles whose measures have a sum of 90°. Since m∠A = 6x+29 and m∠B = x+5, we can write the following equation to solve for x:

6x+29+x+5=90

Solving for x, we get:

6x+29+x+5=90

7x+34=90 (Simplify LHS)

7x+34-34=90-34 (Subtract 34 from both sides of the equation to isolate x)

7x=56 (Simplify)

\frac{7x}{7}=\frac{56}{7} (Divide both sides of the equation by 7 to get rid of x's coefficient)

x=8

Therefore, m∠A=6x+29=6(8)+29=48+29=77°. Hope this helps!

A line with a slope of 3 passes through (2,5). Which choice is an equation of this line? Please help
jek_recluse [69]

Answer:

Top right.

Step-by-step explanation:

So we want a line with a slope of 3 and passes through (2,5).

To do so, we can use the point-slope form.

The point-slope form is:

y-y_1=m(x-x_1)

m is the slope and x₁ and y₁ is an ordered pair.

Thus, let m be 3, y₁ be 5, and x₁ be 2. Thus:

y-5=3(x-2)

Our answer is the top right :)

The body temperatures of adults have a mean of 98.6°F and a standard deviation of 0.60° F. Describe the center and variability o
amid [387]

Answer:

center = 98.6, variability = 0.08

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means with size n of at least 30 can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}

The center is the mean.

So \mu = 98.6

The standard deviation of the sample of 50 adults is the variability, so

s = \frac{0.6}{\sqrt{50}} = 0.08

So the correct answer is:

center = 98.6, variability = 0.08
