Complementary angles add up to 90 degrees.

Therefore, 30 + 3x = 90

3x=60

x=20

Answer:

a = -2

Step-by-step explanation:

Tn = a+(n-1) * d

-902 = a + (101-1) * -9

-902 = a - 900

a = -902 + 900

a = -2

Answer:

outcome, sample space.AND EVENT

Since the chance of a flight being on time is 90%. The probability that all of Erica's flights will be on time is B 66%.

To answer the question, we need to know what probability is

This is the likelihood for an event to occur. It is given by

P(event) = number of required outcomes/total number of outcomes

Now, given that Erica's travel plans include 4 independent flights. The chance of a flight being on time is 90%. So, P(flight) = 90%. Since they are indepent, we multiply their probability.

So, the probability that all of Erica's flights will be on time is P(on time) = P(flight) × P(flight) × P(flight) × P(flight)

= [P(flight)]⁴

= (90%)⁴

= (0.9)⁴

= 0.656

≅ 0.66

= 66%

So, the probability that all of Erica's flights will be on time is B 66%.

Step-by-step explanation:

What's the question?

Answer:

62.7

Step-by-step explanation:

Cos(ang) = Adjacent / hypotenuse

cos(37) = 48/x

x = 48 / cos(37)

x = 62.71

Answer:

x = 60.1

Step-by-step explanation:

- The provided side length is adjacent to given degree

- and we are lookin for the hypotenuse  

SOH CAH TOA stands for,

sinx = opposite / hypotenuse

cosx = adjacent / hypotenuse

tanx = opposite / adjacent

cosine fulfills everything we have provided so we will choose cos

NOTE: x in cosx represent the degree amount

Solving:

cosx = adjacent / hypotenuse

cos(37°) = 48 / x

multiply both sides by x,

cos(37°)x = 48

divided both sides by cos(37°) to get x alone

x = 48 / cos(37°)x

x = 60.1025

Answer:

  20.7°

Step-by-step explanation:

Bearing angle is measured clockwise from north. The geometry can be modeled by a right triangle with the sides equal to the distances north and east of town B. The tangent relation can be used to find the angle.

__

The attachment shows the geometry. The relevant angle relation is ...

  Tan = Opposite/Adjacent

  tanIβ) = 23/61 . . . . . where β is the bearing angle

The angle value can be found using the arctangent function.

  β = arctan(23/61) ≈ 20.659°

The bearing of A from B is about 20.7°.

Answer:

22.5

Step-by-step explanation:

The mean is calculated by taking the sum of the values and dividing by the count.

For instance, for the 11 women, with the mean being 19, we can see that the ages summed to 209:

11 x 19 = 209

And then we can do the same for men:

11 x 26 = 286

And now we can combine the sum and count of the men and women to find the mean for the office:

286 + 209 = 495

495/22 = 22.5

Answer:

Answer:

[tex]r(x) = 0.05 (x^{2}+1 )x-6[/tex]

Step-by-step explanation:

Function r has two complex zeros and one real zero. Based on the instantaneous growth rate, the population decreased between 0 and 6 hours and the population increased after 6 hours.

Answer:  $26,000

Explanation:

i = simple interest

P = 25,000 = amount loaned

r = interest rate in decimal form = 0.04

t = number of years = 1

So,

i = P*r*t

i = 25000*0.04*1

i = 1000

Howie needs to pay $1,000 in interest on top of the $25,000 loaned to him. In total, he needs to pay back 1,000+25,000 = 26,000 dollars.

Answer:

48 : 1 or 48 to 1

Step-by-step explanation:

to find out the answer we have to first find out what 8 feet is in inches as shown below
8 * 12 = 96

then we apply the inch value to a scale factor setup where 96 is the larger set and 2 is the smaller image

96 : 2

find the least common denominator...

96 / 2 : 2 / 2
 = 48 : = 1

and then rewrite the answer

48 : 1

A combination doesn't need to be in a specific order, unlike permutation which needs to go in order.

Step-by-step explanation:

Step-by-step explanation:

Let width be w, length be l

l + w = 35, so w = 35 - l

lw = 306

l(35-l) = 306

35l - l^2 = 306

l^2 - 35l + 306 = 0

(l - 17)(l - 18) = 0

l = 17 or 18

When length = 17, width = 35-17 = 18

When length = 18, width = 35-18 = 17

Answer:

Answer: She read for 10 Days, equation below

Step-by-step explanation:

Number of pages = 180

Rate = 12pages Per day

Number of days read = (180-60) /12

Days read = (total no of page - page left)/page read per day

= 120/ 12 = 10 days

Days remaining = pages left /page per day

=60/ 12 = 5

Answer:

B. 254 cm²

Step-by-step explanation:

Hello!

The formula for the area of a circle is [tex]A = \pi r^2[/tex]

The radius is half of the diameter, given with the formula [tex]D = 2r[/tex]

Using the information, we can first solve for the radius.

The radius is 9

Now we can plug 9 into the area formula:

We are going to use 3.14 for pi

The area is 254.34cm².

We are going to round to the nearest whole centimeter, which is roughly 254cm² or [tex]\boxed{\text{Option B}}}[/tex]
