A salsa recipe uses green pepper, onion, and tomato in the extended ratio 3:5:7. How many cups of tomato are needed to make 105
Serga [27]
To find the answer, we can first find out the proportion of tomato in a cup of salsa in percentage:

7/3+5+7
=7/15

We can then proceed to find the cups of tomato needed in 105 cups of salsa by multiplying the proportion to 105:

7/15×105
=7/5x3 × (5×21)
=7/3 x (3×7)
=7x7
=49

Therefore,49 cups are needed.

Hope it helps!

The potential in a region between x = 0 and x = 6.00 m is V = a + bx, where a = 15.4 V and b = -5.10 V/m.
Minchanka [31]

Answer:

V(0)=15.4\\V(3)=0.1\\V(6)=-15.2

Step-by-step explanation:

The potential in a region between x = 0 and x = 6.00 m is V = a + bx.

Put a = 15.4 V and b = -5.10 V/m.

So, V=15.4-5.10x

To find: Potential at x =0, 3, 6

Solution:

Potential at x = 0:

V=15.4-0=15.4

Potential at x = 3:

V=15.4-5.10(3)=15.4-15.3=0.1

Potential at x = 6:

V=15.4-5.10(6)=15.4-30.60=-15.2

Therefore,

V(0)=15.4\\V(3)=0.1\\V(6)=-15.2
