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

Answers

Answer 1

Answer:

First: 30°

Second: 67°

Third: 83°

Step-by-step explanation:

First: x

Second: y

Third: z = y + 16

Constraints:

x + y + z = 180

y + z = 5x ===> y = 5x - z

Substitution to find first angle x:

x + y + z = 180

x + (5x - z) + z = 180

x + 5x - z + z = 180

6x = 180

x = 30

Substitution to find second angle y:

y = 5x - z

y = 5(30) - z

y = 150 - z

y = 150 - (y + 16)

y = 150 - y - 16

y = 134 - y

2y = 134

y = 67

Substitution to find third angle z:

z = y + 16

z = (67) + 16

z = 83

Answer 2

Answer:

x=30 y=67 z=83

Step-by-step explanation:

The solution is therefore (30,67,83).

What is the sale price of the computer?

Answers

Answer:

Step-by-step explanation:

Subtract.

914 - 886 = 28

Divide by the original price.

28/914 = 0.0306345...

Multiply by 100%.

0.0306345... * 100% = 3.06345%

Answers

60 square feet= $287.00 + $80.00

= $367

1 square feet= $367 / 60

= $6.116666667

= $6.12 (to 2dp) ( answer)

Answer:

60 square feet for 287 = 287/60 = 4.78 per square foot

so ur equation would be : y = 4.78x + 80

a. A has to be the first graph because it starts at $ 25 and it rises as more work needs to get done

b.if you go from 50 up until you get to the line, then look left at the axis is about $38

c. C=25+s*0.25, substitute c=35 and find s

35=25+s*0.25 subtreact 25 from both sides

35-25= s*0.25

10=s*0.25 divide both sides by 0.25

10/0.25=s

6. The Awesome Bowl Factory makes two kinds of bowls. They produce a
basic bowl every 9 minutes and a gigantic bowl every 12 minutes. They
start at 8:00 A.M. At what time are the basic bowl and the gigantic bowl
first produced together?

Answers

Answer: 8.36 a.m

Step-by-step explanation:

To solve this, first we need to calculate the lowest common multiple of 9 and 12.

Multiples of 9 = 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108.

Multiples of 12 = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120.

Here, the lowest common multiple = 36

Therefore, we will add 8.00am plus 36 minutes. This will be:

= 8:00 a.m + 36 minutes

= 8.36 am

The time that the basic bowl and the gigantic bowl are first produced together is 8.36 am.

How many 5-digit numbers are there in which three of the digits are 6, or two of
the digits are 9 ?

Answers

Answer:

The value is [tex]Z = 80[/tex]

Step-by-step explanation:

From the question we are told that

The total number of digit is n = 5

The total possible number of 6 is k = 3

The total possible number of 9 is a = 2

Generally the number of way of representing a 5 digits number(i.e the number of five digit numbers ) in which 3 of the digit are 6 is mathematically represented as

[tex]N = ^ nP_k[/tex]

Here P stands for permutation hence we are going to be making use of the permutation function in our calculators

[tex]N = ^ 5P_3[/tex]

=> [tex]N = 60[/tex]

Generally the number of way of representing a 5 digits number(i.e the number of five digit numbers ) in which 2 of the digit are 9 is mathematically represented as

[tex]M = ^ nP_a[/tex]

[tex]M = ^ 5P_2[/tex]

=> [tex]M = 20[/tex]

Generally the number of 5-digit numbers there are in which three of the digits are 6, or two of the digits are 9 is mathematically represented as

[tex]Z = M + N[/tex]

=> [tex]Z = 60 + 20[/tex]

=> [tex]Z = 80[/tex]
