Answer:
Yes,
Step-by-step explanation:
16/22 = 0.72727272727
24/33 = 0.72727272727
When translated into decimals, they both equal 0.72 reoccurring.
x = 0.72727272727...
10x = 7.2727272...
100x = 72.727272727...
100x - x = 90x = which can be translated/simplified into and
pls give brainliest if this helped !!
Answer:
c=13/14
Step-by-step explanation:
150/11=13 R7
14 because she still needs $7
or 13 because she can work 2hrs walking dogs
S=S1+S2, where S1=12*4=48 cm², S2=0.5*(12-3-3)*(8-4)=12 cm².
S=48+12=60 cm²
Answer:
<u>C.</u>
Step-by-step explanation:
To find which table is correct, you first have to plot the graph. First, pick some easy points on the <em>X</em> axis to graph. Some of these points could be -4, 0 and 4. Now you need to fill in the equation.
<em>Y</em> = -1/2*-4 - 2 = 0
<em>Y </em>= -1/2*0 - 2 = -2
<em>Y</em> = -1/2*4 - 2 = -4
Now you can plot the points and draw your line. Once you have done this, you check each table and see if all the points match up. Doing so would give you answer C.
Also the graph from the equation can be seen below
Numbers 1 and 2 are correct.
Question 3:
We can see in each figure, the number of rows matches the figure amount. For example, figure 1 has 1 row, figure 2 has 2 rows, figure 3 has 3 rows, etc. Another thing we can see is that one block gets added to each column in every figure. If we count starting from 3 and keep adding 1 for each column, we get 22 blocks for one column. In figure 20, there will be 20 rows and 22 columns. We also have to keep in mind that they add 2 extra blocks at the top and bottom that stick out like the ones shown. In total, figure 20 will consist of 442 blocks.
Question 4:
[(2 + f) * (f)] + 2 = b
(2 + f) represents the number of blocks in each column.
(f) represents the number of blocks in each row.
2 represents the two extra blocks in each figure.
Note that f in this equation equals the number of the figure. For example, figure 3 is f = 3
We can test our equation with figure three.
[(2 + f) * (f)] + 2 = b
We have figure three so f = 3. Substitute and solve.
[(2 + 3) * (3)] + 2 = b
[5 * 3] + 2 = b
15 + 2 = b
17 = b
In the example, the number of blocks is 17. Therefore, this equation works for any figure.
Best of Luck!
