However many X's are on the speed, that's how many cars had that speed. For example on the chart, 29 has one X above it; therefore, there was one car that had the speed 29 mph. :)
Answer:
There are 81 girls.
Step-by-step explanation:
First, take what we know and find how many people 1 in the ratio is:
54 / 2 = 27
(in this problem) 1 = 27
Now find how many girls are at the dance by multiplying by three:
27 x 3 = 81
There are 81 girls at the dance.
The unique solution is (-1/2,-5/2), (2,5),
y=2x^2-3, it can be prooved as
-5/2= 2(-1/2)^2-3, so it is (-1/2,-5/2)
y=3x-1
5=3x2-1,so it is (2,5),
Answer:
5.4 inches
Step-by-step explanation:
This is all about ratios proportions and similarity.
First the 8.5 stays the same you scale only the 11 down to 7
because it says to scale length down to 7
so once you scale it down you should get 5.4 inches for the width once you plug it back in
3,254,107
3,000,000 + 200,000 + 50,000 + 4,000 + 100 + 00 + 7
Hundred thousand = 100,000 = 5 zeroes
2<u>00,000
</u>2 is the digit in the hundred thousands place.<u>
