Step-by-step explanation:

The pair of equations that can be used to find x and y are:

x + y = 62

(1.02)x = 7

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here, we have,

The form of the pair of equations would be:

hours worked last week + hours worked this week = total hours worked both weeks equation 1

(1 + percent increase/100) x hours worked last week = hours worked this week equation 2

x + y = 62 equation 1

(1 + 20/100) ×x = y

(1.02)x = 7 equation 2

The two equations can be solved using either of these three methods:

elimination method

substitution method

graph method

Answer:

B, 3 8/9

Step-by-step explanation:

It all comes down to equivalent fractions.

2 1/3 as an improper fraction is 7/3.

1 5/9 as an improper fraction is 14/9. 1/3 = 3/9.

With that being said 7 x 3 = 21 resulting in 21/9.

14/9 + 21/9 = 35/9.

35/9 as a mixed fraction is 3 8/9.

Answer: About 10 ft.

Use Pythagorean's Theorem!

c=[tex]\sqrt{9^2+3^2}[/tex]

9 * 9 = 81

3 * 3 = 9

81 + 9 = 90

[tex]\sqrt{90\\}[/tex] = 3[tex]\sqrt{10}[/tex] ≈ 10 ft.

Answer:c

Use the distance formula to see if all three sides are congruent.

Step-by-step explanation:

An equilateral triangle is a triangle which has three sides with the same lengths. If we check for congruence we are checking to see if all the sides are the same :)

To prove a triangle is an equilateral triangle by using  the distance formula to see if all three sides are congruent, the correct option is C

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

Given;

To prove a triangle is an equilateral triangle

Now, we have to use the distance formula: d = sqrt( (x2 - x1)² + ( y2 - y1 )²)

When 2 sides are congruent it could be a scalene triangle, so it is not enough. All 3 sides must be congruent.

Therefore, the answer will be by use the distance formula of triangle to see if all three sides are congruent.

Answer: A

Step-by-step explanation:

Answer:

88

Step-by-step explanation:

50 - 23 = 27

27 - 16 = 11

50 + 11 + 27 = 88

Answer:

X=8

z=80

Step-by-step explanation:

Okay to find X you gotta find the other angle.

The other angle is 100 which is also vertical To (6x+52)

Vertical angles are equal or congruent so you cna make an eqaution to equal it

6x+52=100

Solve it like a normal equation

x=8

To find Z you gotta realize that 4 angles equal 360 degrees.

We knwo the two vertical angles, 100 and 100. Z is vertical to no name angle so its equal so it can also be Z. Z+Z=2z

Now If you add em all up you should get 360

2z+100+100=360

2z+200=360

Solve from here

z=80

Answer:

17. a  18. c   19. d   20. b

Step-by-step explanation:

Hello, for the first question, you just take the person with the largest number and the person with the smallest number. Kenny (5) and Sammy (0).

For question 18, you just add up all the numbers like this:

0+1+3+5+4+1+1+2+1= 18

And then you divide it by the number of people there which is 9:

18/9=2

For question 19, you arrange all the numbers from least to greatest like this:

0,1,1,1,1,2,3,4,5

And then you count on both ends until it meets the middle. 1 is the middle.

For the last question, you just find the number that appears the most, which is one.

Answer:

Volume = 646.0 cm³

Step-by-step explanation:

The solid is made up of a hemisphere and a cube

Therefore,

Volume of the composite solid = ⅔πr³ + a³

Where,

r = ½(8) = 4 cm

a = 8 cm

Plug in the values

Volume of the composite solid = ⅔*π*4³ + 8³

= 134.04 + 512

= 646.0 cm³ (nearest tenth)

The number of times that josh rolled each number is given so the mean or average of the dice rolls​ is 3.6.

Probability is a branch of mathematics that deals with the study of random events or outcomes.

It is concerned with determining the likelihood of an event or outcome occurring in a given situation.

The probability of an event is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain.

The average of dice roll is:

Average = 1/100 (15 x 1 + 18 x 2 + 14 x 3 + 16 x 4 + 19 x 5 +18 x 6)

Average = 1/100 (15 + 36 + 42 + 64 + 95 + 108)

Average = 1/100 x 36

Average = 3.6

Thus, the answer is 3.6.

B. 658 Hours

Step-by-step explanation:

All you do is divide.

$19 for every hour, it's 2 persons so,

$38 for every hour.

so,

25,000/38

= 657.894736842 which is about 658 so,

= 658 Hours

It would take 658 hours for the robot to pay for itself in labor savings

An equation is an expression that shows the relationship between two or more numbers and variables.

The robot can replace two people doing assembly work that are paid $19 per hour.

Let us assume it would take x hours for the robot to pay for itself in labor savings

(19 + 19)x = 25000

38x = 25000

x = 657.9
