The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 16 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles.

B; 2.25

Step-by-step explanation:

Answer:

A is the answer. 2(n+2)

Answer:

A

Step-by-step explanation:

The sum of a number n and 2 is n + 2

Twice this sum is

2(n+ 2) → A

Answer:

x=-3/4

Step-by-step explanation:

Use the distributive property a(a+b)= ab+bc:

-4x-2=1

Add a 2 to both sides:

-4x=3

Divide both sides by -4:

x=3/-4

This can be rewritten as -3/4

Answer:

72.5 miles/hour

Step-by-step explanation:

When we say "miles per hour" in English this just is simply the question "If Bailey drove for only one hour, how far did she go?". Now mathematically we can find this very easily by simply dividing 290 by 4, which is equal to 72.5. So Bailey travels 72.5 miles every hour.  

If it is confusing about why we do this, think about splitting up 290 miles evenly between 4 hours, how many miles does each hour 'get'. Each would 'get' 72.5 miles. So for every hour Bailey drives she travels 72.5 miles which is the same as saying that she drove at 72.5 miles per hour.

Hope this helps!

3y-14=13

move -14 to the other side

sign changes from -14 to +14

3y-14+14=13+14

3y=13+14

3y=27

divide both sides by 3 to get y by itself

3y/3=27/3

Answer: y=9

Answer:

j = (h-4) / k

Step-by-step explanation:

Unless there is more information given about this question somewhere else in the assignment, I'm assuming you are being asked to solve this equation for j.

If so, then its just a matter of rearranging the equation so that it is in the form

j = (expression containing other variables)

(h-4) / j = k   (multiply both sides by j)

(h-4) = jk  (divide both sides by k)

j = (h-4) / k

Hey!

Lets try -10:

2(3(-10) - 1) = 4(-10) - 6

2(-30 - 1) = (-40) - 6

2(-31) = (-40) - 6

-62 ≠ -46

Incorrect.

--------------------------------

Lets try -5:

2(3(-5) - 1) = 4(-5) - 6

2(-15 - 1) = (-20) - 6

2(-16) = (-20) - 6

-32 ≠ -26

Incorrect.

--------------------------------

Lets try -3:

2(3(-3) - 1) = 4(-3) - 6

2(-9 - 1) = (-12) - 6

2(-10) = (-12) - 6

-20 ≠ -18

Incorrect.

--------------------------------

Lets try -1:

2(3(-1) - 1) = 4(-1) - 6

2(-3 - 1) = (-4) - 6

2(-4) = (-4) - 6

-8 ≠ -10

Incorrect.

--------------------------------

So all the options are incorrect.

--------------------------------

Lets solve for x:

2(3x - 1) = 4x - 6

(2 * 3x) + (2 * -1) = 4x + (-6)

6x + (-2) = 4x + (-6)

6x - 2 = 4x - 6

6x - 2 - 4x = 4x - 6 - 4x

2x - 2 = -6

2x + 2 - 2 = -6 + 2

2x = -4

2x/2 = -4/2

x = -2

Answer:

-1 is the answer

Step-by-step explanation:

Answer:

The vertical distance is 25.825 ft

Step-by-step explanation:

we know that

To find out the vertical distance between Cece and the base of the mountain, subtract the height of the base of the mountain from the height of Cece

Let

x -----> the height of Cece

y ----> the height of the base of the mountain

we have

[tex]x=15\frac{5}{8}\ ft[/tex] ----> is positive because is above sea level

convert to an improper fraction

[tex]x=15\frac{5}{8}\ ft=\frac{15*8+5}{8}=\frac{125}{8}=15.625\ ft[/tex]

[tex]y=-10.2\ ft[/tex] -----> is negative because is below sea level

so

[tex]x-y=15.625-(-10.2)=15.625+10.2=25.825\ ft[/tex]

Remember that -1*(-1)=+1

Answer:

720 shares

Step-by-step explanation:

Find 60% of 1,200, to figure out how many shares Jillian has.

Change 60% to decimal

0.6

Multiply with the total shares

0.6 x 1,200 = 720

720 shares

Jillian owns 720 shares in a catering corporation.

The percentage is defined as a ratio expressed as a fraction of 100.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have to determine 60% of 1,200, to figure out how many shares Jillian has.

Convert 60% into a decimal

⇒ 0.6

Multiply with the total shares

⇒ 0.6 × 1200

⇒  720

Hence, Jillian owns 720 shares in a private catering corporation.

Answer:

C. [tex]h(x)=x-3[/tex]

Step-by-step explanation:

We have been given a function [tex]f(x)=x+3[/tex]. We are asked to find the inverse of the given function.

First of all, we will replace [tex]f(x)[/tex] by y as:

[tex]y=x+3[/tex]

Now, we will interchange x and y variables as:

[tex]x=y+3[/tex]

Solve for y:

[tex]x-3=y+3-3[/tex]

[tex]x-3=y[/tex]

Switch sides:

[tex]y=x-3[/tex]

Therefore, the inverse function for the given function would be [tex]h(x)=x-3[/tex].

Answer:

The running club has 35 members

Step-by-step explanation:

Let

x ----> the total members of the running club

we know that

The total members of the running club multiplied by 5/7 plus 6 must be equal to 31 people

so

[tex]\frac{5}{7}x+6=31[/tex]

Solve for x

[tex]\frac{5}{7}x=31-6[/tex]

[tex]\frac{5}{7}x=25[/tex]

[tex]x=25(7)/5[/tex]

[tex]x=35\ members[/tex]

therefore

The running club has 35 members

Probability of a male having a blood circulation problem, given he's a smoker, is approximately 0.6667.

Step 1:

Identify the given probabilities:

Let [tex]\( P(A) \)[/tex] be the probability that a randomly chosen male has a blood circulation problem, which is [tex]\( 0.25 \)[/tex].

Let [tex]\( P(B|A) \)[/tex] be the probability that a male is a smoker given that he has a blood circulation problem, and it's twice the probability of being a smoker given not having a blood circulation problem.

Step 2:

Calculate [tex]\( P(B|\neg A) \)[/tex]:

Since males with blood circulation problems are twice as likely to be smokers as those without, \( P(B|\neg A) \) is half of [tex]\( P(B|A) \)[/tex], which is [tex]\( \frac{1}{2} \)[/tex].

Step 3:

Apply Bayes' theorem:

[tex]\[ P(A|B) = \frac{P(B|A) \times P(A)}{P(B)} \][/tex]

Step 4:

Calculate \( P(B) \):

[tex]\[ P(B) = P(B|A) \times P(A) + P(B|\neg A) \times P(\neg A) \][/tex]

Step 5:

Substitute values into Bayes' theorem and solve:

[tex]\[ P(A|B) = \frac{(2 \times P(B|\neg A)) \times P(A)}{(2 \times P(B|\neg A)) \times P(A) + P(B|\neg A) \times (1 - P(A))} \]\[ P(A|B) = \frac{(2 \times \frac{1}{2}) \times 0.25}{(2 \times \frac{1}{2}) \times 0.25 + \frac{1}{2} \times (1 - 0.25)} \]\[ P(A|B) = \frac{0.25}{0.25 + 0.125} \]\[ P(A|B) = \frac{0.25}{0.375} \]\[ P(A|B) \approx 0.6667 \][/tex]

Thus, the probability that a male has a blood circulation problem, given that he is a smoker, is approximately 0.6667.

Six to the third power means to multiply 6 by itself 3 times.

The standard exponential function is expressed as y = ab^x. The value for the simplified form of 6 to the third power is 216

The standard exponential function is expressed as y = ab^x

Given the following parameters
