in a certain chemical the ratio of zinc to Copper is for 211 a jar of the chemical contains 385 grams of copper how many grams of zinc does it contain.

Answer:

A. z*(2*4)

Step-by-step explanation:

(z*2)*4

=4(2*z)

=4(2z)

=8z

A. =z(2*4)

=z(8)

=8z

We start with:

[tex](z*2)*4=8z[/tex]

Let's check all the answers:

[tex]A= 8z\\B=4z+8\\C=2z+4\\D=8z^2[/tex]

We can see that A is the same as what we started with.

Answer:

4 on top three on bottom?

Step-by-step explanation:

Answer:

Hate to break it to you, but it actually is 3

Step-by-step explanation:

You need to make sure 3/4 is equal to the fraction.

It doesn't matter how many slots there are.

The fraction that it's going to be equal to is 9/12

To get the 12 on the bottom, you need to multiply the 4 by 3

Because you want to get an equivalent expression, you have to the same thing to the top.  So 3 x 3 is 9.

Both slots are going to have a 3 in it

Using the area of a rectangle, it is found that the area of Gloria’s banner is 4 times larger than the area of Greg's sign.

The area of a rectangle of length l and width w is given by:

[tex]A = lw[/tex].

For Greg, the sign was 15 1/2 inches wide and 11 inches long, hence the area in square inches is given by:

[tex]A_{gr} = 11 \times 15.5 = 170.5[/tex]

For Gloria, the poster was 15.5 inches wide and 44 inches long, hence the area is of:

[tex]A_{gl} = 44 \times 15.5 = 682[/tex]

The ratio is given by:

[tex]r = \frac{A_{gl}}{A_{gr}} = \frac{682}{170.5} = 4[/tex]

The area of Gloria’s banner is 4 times larger than the area of Greg's sign.

Answer:

The sequence 7, 14, 28, ... is a geometric sequence with first term 7 and common ratio 2. The explicit formula for a geometric sequence is a_n = a_1 r^(n-1), where a_n is the nth term, a_1 is the first term, and r is the common ratio. In this case, a_n = 7 (2)^(n-1).

Here are the first few terms of the sequence:

n = 1: a_1 = 7

n = 2: a_2 = 14

n = 3: a_3 = 28

n = 4: a_4 = 56

n = 5: a_5 = 112

As you can see, the formula works for all values of n.

Answer:

y=-2x-3

Step-by-step explanation:

The set up is always y=mx+b. You have to find m (m is slope) and b (b is y-axis). Since the line goes down, it has a negative slope. From the first point to the second, it goes down 4 and over 2. If you divide 4/2, you get 2 for the slope. The y-axis is just where the point meets the y-axis line and in this example, it meets at -3 so that is your b value.

Answer:

I would assume they drove a car.

If so, then Dallas to Houston: 239.3 miles.

Then, Houston to Austin: 165.3 miles

Shortest route back to Texas: 913.5.

I used g o o g l e m a p s to find my answer.

Now add the numbers up:

239.3+165.3+913.5= 1318.1

They traveled 1318.1 miles in all.
