We know that

15 baseball cards cots $9.00

So in order to get 30 all we need to do is times what we know by 2

15x2 = 30

9 x 2 = 18

Therefore, 30 baseball cards will cost $18.00

Which triangle has a bigger area:
irakobra [83]

Hello there!

Answer:

Triangle 2

Step-by-step explanation:

To determine which triangle has the bigger area, we would need to figure our the area of the triangles.

To solve for the area of the triangles, we would use the formula length × width × height or l × w × h

They gave us the information to the triangles in the question, so we would just solve.

Triangle 1: 300 *400*500= 60,000,000

Triangle 2: 300*400*700=84,000,000

When you finish solving, you would see that triangle 2 has the bigger area.

Triangle 2 would be the CORRECT answer because it has a bigger area than Triangle 1.

Given the relations A: (3,2), (5,3), (6,2), (7,4) which statement is true?
In-s [12.5K]

Answer:

Option 3.

Step-by-step explanation:

The given relation is

A= {(3,2), (5,3), (6,2), (7,4)}

A relation is called a function, if there exist a unique value of y for each value of x.

In relation A, there exist unique output for each input. So, A is a function.

If a relation is defined as R = {(a,b), a∈R,b∈R}, then inverse of R is

R⁻¹ = {(b,a), a∈R,b∈R}

So, inverse of A is defined as

A⁻¹= {(2,3), (3,5), (2,6), (4,7)}

Here, the value of y are 3 and 6 at x=2.

For x=2, there exist more than one output. So, A⁻¹ is not a function.

Therefore, the correct option is 3.

Determine the SCALE FACTOR. Original image: 1.5 inches tall, 2 inches long. Scale Drawing: 3.75 inches tall, 5 inches long. (pic
Virty [35]

Answer:

scale factor is 2.5

Step-by-step explanation:

Notice that the original image is smaller than the scale drawing. Examine the ratios of the sizes:

Image/ Original :

height:  3.75 in / 1.5 in = 2.5

length:   5 in / 2 in = 2.5

The scale factor is clearly 2.5

I don’t understand the question
Anni [7]

Answer:

Try 31 degrees/ Hard to explain but try it

Step-by-step explanation: cause between angle a, c, b - and angle a, o , c - their is an intersect. on that intersect onside is 62 degrees and the other side is 118 degrees; now thats a 180 degrees angle cause the base of the intersect is straight. Now this intersect is connected to the obtuse angle of the bottom triangle which is 118 degrees. Knowing that you can figure out the other corners of the traingle. The last two acute angles of to be congruent.

What is the value of X?<br> -5x-5y=25<br> 3x+5y=-21
enyata [817]

Answer:

x = -2

Step-by-step explanation:

Solution:

-5x - 5y = 25    -(1)

3x + 5y = -21     -(2)

Adding (1) and (2),

-5x - 5y + 3x + 5y = 25 - 21

-5x + 3x -5y + 5y = 4

-2x = 4

x = 4 / -2

Therefore, x = -2
