Answer:

144

Step-by-step explanation:

to find the missing angle in side of the triangle we subtract 111 and 33 from 180

180-111-33=36

so the angle inside of the triangle equals 36 to find the one on the outside of the triangle we subtract 36 from 180

180-36 which equals 144 so 1=144

Answer:

54

Answer:

Approximate difference between 1 mile and 2 km in meters = 390.66meters

Step-by-step explanation:

I mile =1609.34meters

also 1000m = 1km

therefore 2km = 2 x 1000= 2000m

Approximate difference = 2000m - 1609.34m

=390.66 meters.

 Approximate difference between 1 mile and 2 km in meters = 390.66meters

Answer:

14x+3

Step-by-step explanation:

The given expression is as follows :

4x + 3(2x +1) + 4x

We need to find the equivalent expression for the above.

So,

4x + 6x +3 + 4x

Adding x terms,

14x+3

Hence, the correct equivalent expression is 14x+3.

Answer:

1.37741046832

Step-by-step explanation:

Answer:

a) "impossible event"

b) "certain event"

c) Letter A.

Step-by-step explanation:

a) An event with probability 0 is said to be:

These events are called "impossible events" (but there are more complex cases where we can have probabilities 0, and the events are not necessarily impossible events)

b) An event with probability 1 is said to be

An event with a probability of 1 is an event that will happen, these events are called "certain event"

c) The probability for each outcome of an unbiased experiment of N different outcomes will be 1/N

for example, for a 6-side dice we have 6 outcomes, then the probability of each outcome is 1/6.

For the coin, we have 2 outcomes, then the probability of each outcome is 1/2

Probability of getting a head = 1/2 = 0.5

In the image, we can see that letter A is on the 0.5 value, then the correct answer here is A.

Answer:

[tex]a=4\ m/s^2[/tex]

Step-by-step explanation:

Given that,

The velocity of a car increases from 4 m/s at 2 sec to 32 m/s at 9 sec.

We need to find the car's average acceleration. It can be given by the change in velocity divided by the change in time. So,

[tex]a=\dfrac{v-u}{t_2-t_1}\\\\a=\dfrac{32-4}{9-2}\\\\a=4\ m/s^2[/tex]

So, the car's average acceleration is equal to [tex]4\ m/s^2[/tex].

Step-by-step explanation:

Answer:

A)

Decay

B)

Initial value is 5.

C)

The decay factor is 0.75.

D)

75%

Step-by-step explanation:

An exponential function is given by:

[tex]f(x)=a(r)^x[/tex]

Where a is the initial value and r is the rate.

We have the function:

[tex]y=5(1/4)^x[/tex]

So, a = 5 and r = 1/4.

A)

Remember the guidelines:

Our rate is 1/4 or 0.25.

It is less than 1, so our function is exponential decay.

B)

The initial value is the value in front of our rate.

So, our initial value in this case is 5.

C)

The decay factor will be 1 - r, where r is our rate.

Since our rate is 0.25, our decay factor is 1 - 0.25 = 0.75.

So, we are decaying by a factor of 0.75.

D)

To convert a decimal to a percent, we move the decimal dot two places to the rght and add a percent sign.

So, 0.75 will be 75.0 % or smply 75%.

It is a 75% decay.

Step-by-step explanation:

Answer:

a. 1

b. any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1

Step-by-step explanation:

Answer and explanation:

a) This value is equal to one because it is just the number divided by itself.

b) Since any number divided by itself is equal to 1, 6^3/6^3 also has to equal to one. This also means that when we bring the 6^3 up to the numerator, the equation 6^3-3, which simplifies into 6^0 also has to equal 1, because it is equivalent to being divided by itself.

Answer:

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((2-(-4))²+(1-(-3))²)

d=√(6²+4²)

d=√36+16

d=7.21110255...

d=7.2

Step-by-step explanation:

The distance between the points on the coordinate plane is 7.2 units.

Coordinate geometry is the study of geometry using the coordinate points.  It provides a link between geometry and algebra through line graphs and curves.

For the given situation,

The points are (x1, y1) be (–4, –3) and (x2, y2) be (2, 1)

The formula for the distance between points,

[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]

On substituting the above points,

⇒ [tex]d=\sqrt{(2-(-4))^{2}+(1-(-3))^{2} }[/tex]

⇒ [tex]d=\sqrt{6^{2}+4^{2} }[/tex]

⇒ [tex]d=\sqrt{52}[/tex]

⇒ [tex]d=7.211[/tex] ≈ [tex]7.2[/tex]

Hence we can conclude that the distance between the points on the coordinate plane is 7.2 units.

Answer:

2x-60=180

Step-by-step explanation:

RQS = x-6

the two angles add to make 180 because they are on a straight line

so x + x-6 = 180

therfore, 2x+6 = 180

Answer: 63 mph

Step-by-step explanation:

Speed is determined by dividing the distance traveled by the time taken to travel it.

Speed = Distance of highway / Time spent on highway

= 157.5 / 2.5

= 63 miles per hour

Answer:

5 units

Step-by-step explanation:

Answer:

I think 5.

Step-by-step explanation:

You'd do this backwards.

51 ÷ 4 = 12.75

12.75 - 7 = 5.75.

You could either round that to 6 or keep it at 5.

Answer:

I believe it is 5 or 6. the answer I got was 5.75 so I am leaning towards 6 but I would let someone else answer.

Step-by-step explanation:

ok so we have 51 so then you would divide by 4 and subtract 7.

Answer:

C: $30/hr

Step-by-step explanation:

In order to find the rate per hour you must divide: 150 ÷ 5

Which will give you 30

Also if you took away the 0 in "150" then it would be like says "15 ÷ 5" which is 3 but then you have to add the zero back making it 30

Therefore your overall answer is going to be C, $30/hr

Step-by-step explanation:

The minimum average score Ethan can earn on his fifth and final test is option (D) 60% is the correct answer.

An average of a list of data is the expression of the central value(mean) of a set of data. Average is calculated by adding quantities together and dividing the total by the number of quantities.

For the given situation,

The scores for 4 exams are 68%,72%, 85%, and 90%.

Let the score for the fifth test be x.

Formula for the average,

[tex]A = \frac{Sum of individual scores}{Total number of tests}[/tex]

⇒ [tex]75=\frac{68+72+85+90+x}{5}[/tex]

⇒ [tex]375=315+x[/tex]

⇒ [tex]x=60[/tex]

Hence we can conclude that the minimum average score Ethan can earn on his fifth and final test is option (D) 60% is the correct answer.
