Answer:

Mr. Sato needs 9 more magnets.

Step-by-step explanation:

The 24 students will form 12 pairs. The total number of magnets needed is 12*3 = 36. Mr. Sato  gave out 9*3=27 magnets already and so he will need 36 - 27 = 9 more magnets.

Answer:

x=20

Step-by-step explanation:

just use the pythagorean theorem!!

square 12 and 16 to get 144 and 256

add those together to get 400, and then just take the square root of 400 (which is 20)

this means that x=20!

hope this helps!! :)

Answer:

y = 250x

Step-by-step explanation:

<em>The options are not given; however, the question can still be answered.</em>

Given

Direct Proportion:

In 20 minutes, y = 250 bottles

Required

Determine the graph

<em>In the first 20 minutes, y = 250</em>

<em>In the next 20 minutes, y = 250 + 250 = 500</em>

<em>In the next 20 minutes, y = 500 + 250 = 750</em>

<em />

This gives a arithmetic sequence:

250, 500, 750, ........

Next, is to determine the equation of the sequence using;

T_n = a + (n - 1)d

In this case;

T_n = y

x = n

a = 250

d = 750 - 500 = 500 - 250 = 250

Substitute these values in the above formula;

y = 250 + (x - 1) * 250

Open Bracket

y = 250 + 250x - 250

Collect Like Terms

y = 250x + 250 - 250

y = 250x

Hence; the graph that shows the given description is the graph with equation y = 250x

1. 3500(1+ \frac{.05}{4}) ^{4*10}
3500(1+.0125) ^{40}
3500(1.64) = 5740

2. 25300(1+ \frac{.045}{12} ) ^{12*25}
25300(1+.00375) ^{300}

Which expression is 12 times as large as the expression 7 plus 91?
Over [174]

Answer:

A

Step-by-step explanation:

here's how I got it A and C are similar but C will have a different answer because you will multiply 12*7 then add 91 that will equal 175 but it wants the answer that is 12 larger than 7 + 91. when it is in parenthesis it goes first so then you do 7+91 first and that is 98. then multiply 12*98=1176 and that is the correct answer because it is 12 times the sum of 7 and 91.
