Answer:

\frac{15}{2}

Step-by-step explanation:

If you were to turn 7 1/2 into a(improper) fraction would need to do this:

first say the entire problem aloud

"7 wholes and 1 half"

Now think, how many half's are in one whole?

2.

so if there were 2 half's in each whole and there were 7 wholes, you would multiply 7x2

14.

Then simply add the other half you started with

15 halfs.

then turn it into a fraction.

\frac{15}{2}

hope this helps ^-^

Answer: At the moment 7 1/2 is a fraction

an improper fraction would be 15/2

Step-by-step explanation:

  1. Multiply the denominator by the whole number (7*2=14)
  2. Add the answer from step 1 to the numerator (14+1 =15)
  3. Write the answer from step 2 over the denominator (15/2 --> FINAL ANSWER)

In the diagram, ABCD is a part of a right angled triangle ODC. If /AB/= 6 cm,
Andreas93 [3]

Answer:

1) 13.3 cm

2) 48.3 cm

Step-by-step explanation:

1) Right angled triangle ODC and right angled triangle OAB are similar because AB//DC. The two triangles have the same proportion and are equiangular (having equal angles) but have different lengths.

Let OB = x, OC = OB + BC = x + 8

Therefore:

\frac{OC}{OB}=\frac{DC}{AB}  \\\frac{x+8}{x}=\frac{15}{6}\\15x=6(x+8)\\15x=6x+48\\15x-6x=48\\9x=48\\x=5.3\ cm

The height of triangle ODC = OC =  x + 8 = 5.3 + 8 = 13.3 cm

2) Using Pythagoras theorem:

OD² = OC² + DC²

OD² = 13.3² + 15²

OD² = 401.89

OD = √401.89 = 20 cm

2) perimeter of triangle ODC = OD + OC + DC = 20 + 13.3 + 15 =48.3 cm

I'll give brainliest<br><br> reflect (-4,4) in the x-axis
harina [27]

Answer:

(-4,-4)

Step-by-step explanation:

Anytime you reflect a coordinate point across the x-axis, the y-coordinate becomes its opposite and the x-coordinate stays the same.

In this coordinate: (-4,4)

Reflecting (-4,4) across the x-axis means the x-coordinate (-4) would stay the same and the y-coordinate (4) would become its opposite (-4).

The new coordinates after being reflected across the x-axis are (-4,-4).
