The answer is the third answer because it is the only option where the number 45 is multiplied by something bigger than 1. If something is multiplied by something smaller than one then it will be smaller than the number multiplied.

Aka: 45x0.8 is 36, because 0.8 is smaller than one

Drink A is 20% water by weight, and drink B is 35% water by weight. How many fluid ounces of drink A must be added to 80 oz of d

luda_lava [24]

Answer:

40 fluid ounces of drink A must be added to 80 oz of drink B to have a drink whose final proportion of water is 30%

Step-by-step explanation:

35% of 80 oz of drink B = 0.35(80) = 28 oz

0.20(A) + 0.35(80) = 0.30(A + 80)

0.20A + 28 = 0.30A + 24

Daisy making a memory box in the shape of the cube.The total volume is 216 cubic inches.What are the measurements of the length,

Lera25 [3.4K]

Answer:

The length, the width and the height of the box is 6 inches.

Step-by-step explanation:

Given:

Daisy making a memory box in the shape of the cube.

The total volume is 216 cubic inches.

Now, to find the length, width and height of the cube.

Volume of cube = 216 cubic inches.

As, the sides of the cube are having same length.

Thus, the measurements of length, width and height of the cube are same.

Now, to get the side of the cube we put formula:

$Volume=(side)^3\\\\216=(side)^3$

Using cube root on both sides:

$6=side\\\\Side=6\ inches.$

Therefore, the length, the width and the height of the box is 6 inches.

The nth term of a sequence is given by 20-n^2 a) find the third term of the sequence b) which term in the sequence is the first

ehidna [41]

Answer:

The third term is 11.

The first negative term is the fifth term.

Step-by-step explanation:

If the nth term of the sequence is given by the expression 20-n^2, to find the third term, we just need to use the value of n = 3 in the expression:

20 - (3)^2 = 20 - 9 = 11.

To find which term is the first to have a negative value, we can solve the inequation 20 - n^2 < 0:

20 - n^2 < 0

n^2 > 20

n > 4.47

The first term to have a negative value is the fifth term:

20 - 5^2 = 20 - 25 = -5
