Answer: 5 yards

Step-by-step explanation:

1. Look at the vertical parts of the drawing from right to left

2. Notice that the longest vertical part is 11 yards

3. Notice that the other labels vertical part is 6 yards

4. Notice that the third vertical part, the one with the ? is 11 yds - 6 yds since the two shorter vertical parts would make a line as long as the longest vertical part of they were put together. Since this is the case the missing part is 11 yds-6 yds = 5 yds.

3x - 4y = 7

Alina [70]

3x - 4y = 7
-(3x + 2y = -5)

= 0 - 6y = 12
-6y = 12
y = -2
The resulting equation would be y = -2.

Answer:

y = 3x - 1

Step-by-step explanation

We manipulate the scatter plot feature in Ms. Excel then we simply add the linear trend line displaying the equation on the chart.

The excel output is attached below.

The relation exhibited by the data set is y = 3x - 1; given the value of x, the value of y is obtained by multiplying x by 3 and subtracting 1 from the result.

For the upcoming holiday season, Dorothy wants to mold 20 bars of chocolate into tiny pyramids. Each bar of chocolate contains 6

abruzzese [7]

Answer:

The largest number of pyramids she can make from 20 bars of chocolate is:

A. 180

Step-by-step explanation:

Firstly, you must find the volume of the 20 bars of chocolate, remember that each bar contains 6 cubic inches of chocolate (6 in^3), so:

Volume of the bars = 6 in^3 * 20
Volume of the bars = 120 in^3

Now, you must find the volume of each pyramid, using the next formula:

Volume of a pyramid = 1/3 B * h

Where:

B = area of the square base.

h = height of the pyramid.

How these values are given in the problem, we only replace the values in the formula:

Area of a pyramid = 1/3 (1 in^2) * 2 in
Area of a pyramid = 2/3 in^3

Finally, we divide the volume of the bars in the volume of each pyramid:

Total number of pyramids = 120 in^3 / 2/3 in^3
Total number of pyramids = 180

how many even numbers less than 1000 can be formed from the given digits 0,2,3,5; if repetition is not allowed ?

Lunna [17]

Answer: 2 numbers

Step-by-step explanation:

Since we are looking for even numbers, 0 and 2 must be the last number.

So if we have 0 at the end, there are 6 possibilities:

2350, 2530, 3250, 3520, 5230, 5320. None of these are less than 1000.

But, if we have 2 at the end, then we have 6 possibilities again:

0352, 0532, 3052, 3502, 5032, 5302. Only two of these are less than 1000.

So the only possibilities are 0350 and 0530, and so there are 2 possibilities.
