An "a" value of less than 1 produces a graph with an exponential decay . True or false ?

in a certain chemical the ratio of zinc to Cooper is 4 to 19 A jar of the chemical contains 760 grams of cooper how many grams o

WARRIOR [948]

It contains 160 grams of Zinc. Given that, the ratio of Cooper is 19 to Copper grams of 760 grams. Divide 760 grams by 19 equals 40. Then just multiple 40 by the ratio of Zinc given of 4. Leading to an answer of 160 grams of Zinc.

Can I Get Help With This:

Agata [3.3K]

Answer:

See the attached

Step-by-step explanation:

<u>Rectangular prism</u> — the lower case letters l, w, h in the formula stand for the values of Length, Width, and Height of the prism. Put the numbers in the formula and do the arithmetic. (As you know, when numbers are written next to each other, it means they are multiplied.)

___

<u>Triangular Prism</u> — The formula is essentially ...

V = Bh

where B is the area of the (triangular) base of the prism, and h is its height (or length in this case). The area of the triangular base is given by the formula ...

B = (1/2)bh

where b is the base of the triangle (10 mm) and h is the height of the triangle (12 mm). The fact that the sides of the triangle are 13 mm is irrelevant for the volume calculation (but will be important for surface area calculation).

So, some confusion could arise here because the variable h is used for two different measurements of this prism. The attachment tries to sort it out for you using colors and arrows to identify what is what. (I apologize for the green not coming out very clear. The number in the formula is the same 10 mm number indicated on the prism diagram.)

Trava [24]

Answer:

Eli has to run for 2.25 minutes at this pace to win the bet.

Step-by-step explanation:

At his last track meet, Eli ran the 400-meter dash in 54 seconds.

So, the speed of Eli's run is $\frac{400}{54} \times 60 = 444.44$ meters per minute.

Now, if Eli is determined to run a whole kilometer with the same speed, then it will take Eli to run 1 kilometer within $\frac{1000}{444.44} = 2.25$ minutes.
