Answer:

129

Step-by-step explanation:

Divide 1290 by 10 and you get 129

Answer: 129 tens

Step-by-step explanation:

1290/10=129

129x10=1290

Answer: see below

Step-by-step explanation:

Vertical line test determines which graph is a function.

The graph should pass the vertical line only once if it’s a function.

So we can see that it is the left V-shaped graph.

The graph number [2], represents a function.

A mathematical function is made up of terms (constants and variables) separated by mathematical operators having a dependent and independent variable. A mathematical equation is used to equate two expressions. For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which y exists.

We have some graphs of relations as shown.

Only the graph number [2], represents a function as for a single value value of [x], a single unique value of [y] exists.

Therefore, the graph number [2], represents a function.

Answer:

A) 33

B) 58

Step-by-step explanation:

A is 33 because supplementary angles add up to 180 in total. 180 - 147 = 33, so its supplementary angle would be 33 degrees.

B is 58 because complementary angles add up to 90 in total. 90 - 32 = 58, so the complementary angle would be 58 degrees.

Answer:  33° and 58°

Step-by-step explanation:

147° and 32°

Two angles are called complementary when their measures add to 90 degrees. (90° - 32°) = 58°

Two angles are called supplementary when their measures add up to 180 degrees.  (180°-147°) = 33°

Answer:

Step-by-step explanation:

here's a somewhat answer, and how to solve it

lets assume that all "60 cm wire is used to make a rectangle"

h = a

w = a + 3

the perimeter of the rectangle is

a + a + a + 3 + a + 3 = 60

4a = 54

a = 13.5

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

height = 13.5

width = 16.5

BUT, the problem says "not all the wired is used"

how much? 59? 58? 57.... the lowest value for the shortes side is 1

h = 1

w = 1 + 3 = 4  

perimeter : 1 +4 + 4 + 1 = 6cm

Answer:

m = - 1

Step-by-step explanation:

m = -4 - m + 2    Combine

m = -2 - m          Add m to both sides

m+m = - 2          Combine

2m = - 2            Divide by 2

m = -2/2

m = - 1

m=−(4+m)+2

Simplify both sides of the equation.

m=−(4+m)+2

m=−m+−4+2

m=(−m)+(−4+2)

m=−m+−2

m=−m−2

Add m to both sides.

m+m=−m−2+m

2m=−2

Divide both sides by 2.

2m/2=−2/2

m=−1

Step-by-step explanation:

Answer:

C right 18, down 12

Step-by-step explanation:

Well firstly,

you should focus on the x in both the previous and after location of the object.if you minus 12 from the after point (12,-2) by -6 from the previous point (-6,10) for the object, you'll get 18 which is positive, which means that the object will moves to the right side of the graph →

12 - (-6)

= 18

Next,

you should now focus on the y in both the previous and after location of the object.you should minus -2 by 10 and you'll get -12, which means that the object will moves to the down side of the graph ↓

-2 - 10

= -12

So, the object will move 18 boxes to the right and 12 boxes down to achieve the after, final or last location as stated in the question (12,-2)

Answer:

[tex]\frac{15}{20} x-2=\frac{8}{20}[/tex]

Step-by-step explanation:

[tex]\frac{3}{4} x-2=\frac{2}{5}[/tex]

3/4 and 2/5 have a common denominator which is twenty so you can rewrite the equation with just knowing that

[tex]\frac{3}{4} =\frac{15}{20}[/tex]

[tex]\frac{2}{5} =\frac{8}{20}[/tex]

[tex]\frac{15}{20} x-2=\frac{8}{20}[/tex]

You can then multiply both sides by twenty to solve this equation.

Hope this helps.

Step-by-step explanation:

GCF is greatest common factor, which means that it is the greatest number all the numbers can be divisible by

for these numbers it is 12

Hey there!

Finding the GCF (Greatest Common Factor) of 12, 24, & 48

List of the factors

• 12: 1, 2, 3, 4, 6, & 12

• 24: 1, 2, 3, 4, 6, 8, 12, & 24

• 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, & 48

Common factors

• 1, 2, 3, 4, 6, & 12

Biggest numbers out of the factors

• 6 & 12

GREATEST common factor

• 12

Therefore, your answer is: GCF (Greatest Common Factor) → 12

• Option A.

Good luck on your assignment and enjoy your day!
