Answer:
1.3cm
Step-by-step explanation:
The scale from the actual coin to the photo is 8 mm to 2 cm In the photo,
converting 8mm to cm = 0.8 cm
using ratio and proportion,
if 2cm = 3.25 cm
then 0.8cm = ? less
if less then more devides.
thus ; (0.8cm ÷2cm ) × 3.25cm =
( 0.4) × 3.25cm = 1.3cm
therefore the distance across the actual coin is 1.3cm.
Answer:
∠TUV = 120°
Step-by-step explanation:
Since this figure is a kite, we know that; ∠TUV ≈ ∠TWV, so first we solve for x:
9x - 6 = 7x + 22
2x - 6 = 22
2x = 28
x = 14
Now, substitute 14 in for x, in the equation for ∠TUV:
∠TUV = 9x - 6
∠TUV = 9(14) - 6
∠TUV = 126 - 6
∠TUV = 120°
Hope this helps!

Answer:
No, it is not a right triangle
Step-by-step explanation:
A scalene right triangle comprised of integers must have the same ration as 5:4:3, and 5:6:8 is not it.
Answer:
see explanation
Step-by-step explanation:
Given
10 = 7 - m ( subtract 3 from both sides )
3 = - m ( multiply both sides by - 1 )
- 3 = m , or
m = - 3
As a check
Substitute m = - 3 into the right side of the equation and if equal to the left side then it is the solution
7 - m = 7 - (- 3) = 7 + 3 = 10 = left side
Thus m = - 3 is the solution to the equation
