Answer:
d = 1.2e
30 dollars
Step-by-step explanation:
To write an expression, define the variables. E will be the number of euros and d will be dollars.
"Euro was equal to about 1.2 American dollars" is one euro equals 1.2 and two euros equals 2.4. So the expression is d = 1.2e.
This means if I have 1 euro, I have 1.2*1 = 1.2 dollars. If I have 2 euros, I have 1.2*2 = 2.4 dollars.
If I have 25 euros then d = 1.2*25 = 30 dollars.

Answer:
2.
Step-by-step explanation:
Rotating a figure about the midpoint of its diagonal, the figure will coincide with its pre-image two times: at 180° and at 360°.
This is different than rotating about the origin; for a rotation about the origin, a 180° rotation does not always coincide with the pre-image.
hope that answers ur question :))))
Answer:
8.3 cm
Step-by-step explanation:
1. Find the volume of the small cylinder (volume of a cylinder = πr² · h)
π(4.5²) · 17 = 1080.945 cm³
2. Set up the equation to find the volume of the big cylinder
πr² · 5 = 1080.945
3. Divide both sides by 5
πr² = 216.189
4. Divide both sides by π (3.14)
r² = 68.85
5. Square root both sides
r = 8.3 cm (rounded to the nearest tenth)
