Answer:

76 birds

Step-by-step explanation:

Let x = the number of birds

Let y = the number of cats

x + y = 35       y = 35 - x

4.50x + 8.50y = 221.50       Multiply the whole equation by 100.

450x + 850y = 22150

450x + 850(35 - x) = 22150

450x + 29750 - 850x = 22150

-100x = -7600

x = 76 birds

If logM/N=5 and logP/N=7, what can you say about the relationship between M and P?. . A. M=2P. B. P=2M. C. P=100M. D. P=10M
liubo4ka [24]
<span>log (M/N) = log M - log N
 so log M - log N = 5
log (P/N) = log P - log N
so log P - log N = 7
 If you subtract equation 2 from equation 1, you have log M - log P = -2
 That means that log (M/P) = -2 ----> 10^-2 = M/P ---> P = 100M</span>

At a local acoustic guitar shop, the lute maker sets the strings of the guitars to a height of between 2/32 and 4/32 inches abov
Korolek [52]

Answer:

A: 3/32+1/32 inch

Step-by-step explanation:

So we have the measurements 2/32 and 4/32. We are told the heights range between these two measurements.

What's between 2/32 and 4/32? 3/32.

Since the problem says "between", that must mean 2/32 and 4/32 are the limits of the height.

Now, if we add or subtract 1/32 from 3/32, we get the previous measurements listed.

Hope that helps!
