Answer:
Step-by-step explanation:
Good Question but i don't know
D varies directly with t means
d=kt
105=3k
divide both sids by 3
35=k
d=35t
when t=8
d=35(8)
d=280
B
Answer:
180 in²
Step-by-step explanation:
the area of a rectangle = length × width
here length = 15 in and width = 12 in, hence
area = 15 × 12 = 180 in²
Answer:
42 ounces of yellow paint.
Step-by-step explanation:
- To make three cups of dark orange, you just need to remember that to make one cup you need: 7 ounces of red paint and 1 ounce of yellow paint. Then, to make three cups, we just have to multiply these proportions by three,which means 7x3 ounces of red paint =21 ounces of red paint, plus 3x1 ounces of yellow paint =3 ounces of yellow paint. Then we need 21 ounces of red paint and 3 of yellow paint to make three cups of dark orange.
- To make one cup of light orange, we need 13 ounces of yellow paint, and 3 ounces of red paint. Then, to make three cups, we just multiply this proportion by 3, as follows: 13x3 ounces of yellow paint = 39; and 3x3 ounces of red paint =9. Then we need 9 ounces of red paint and 39 of yellow paint to make three cups of light orange.
- Adding up the amount of ounces we need to make dark orange and light orange, we get a total amount of 21+9=30 ounces of red paint and 3+39=42 ounces of yellow paint to make three cups of light orange and three cups of dark orange.
