Answer:

110, 15%

Step-by-step explanation:

So for the first problem, recall that there is 100%. 12% of the answers on a test were missed.

There are 125 questions on the test.

To find the answer, what we can do it multiply 125 by 100%-12%

So 125*88%

THis can be looked at as:

125*.88

=

110

So we know the first answer is 110, now lets move onto the next one.

There a few ways of diong this, we could do 100%- each of the answers, and then multiply that by 2760 and see if we get 2400, but there is an easier way of doign this.

Take your 2760, and divide it by 2400. This will get you 1.15. So 2400 is increases by .15. This is equal to an increase of 15%.

There is a catch to this one however, when you divide 2400 by 2760, which should get you 85%, it gets you 86%. This would be 14%. So the answer seems to be 15%, but if not, its none of the above.

So answers:

110 and 15%(or none of the above)

Hope this helps! I am sorry about the bottom answer though, but 15% makes the most sense to me.

Answer:

1.  Carrie got 15 of the 125 problems correct

12% or 125 = 15

12% * 125 = 0.12 * 125 = 15

2. "Not Here"

$2400 out of $2760 is %?

2400 ÷ 2760 = 0.8696

0.8696 • 100 = 86.96%

Hope this helps =)

The sum of two numbers is 110. The larger number is 2 less than 7 times the smaller. Find the larger number.
kumpel [21]
We call two numbers a and b, notice a>b
<span>The sum of two numbers is 110: a+b=110
</span><span>The larger number is 2 less than 7 times the smaller: a=7b-2
And by replacing a=7b-2 we have an equation: 7b-2+b=110
or 8b=110+2, and 8b=112, that means b=112:8= 14

We have two numbers: 14 and 96</span>

Solve -52 = 4m for m
ZanzabumX [31]

Note the equal sign. What you do to one side, you do to the other.


Isolate the variable. Divide 4 from both sides


(-52)/4 = (4m)/4


m = -52/4


m = -13


-13 is your answer for m



hope this helps

Can i have some help
Andrews [41]

Answer: g(x) = 3/2 x + 9

Step-by-step explanation:

h(x) = -2/3 x - 1

perpendicular lines always have the opposite sign, reciprocal slope

so, the slope of the perpendicular line would be: m = 3/2

y = mx + b

y = 3/2 x + b

plug in (-4, 3) to find b

3 = 3/2 (-4) + b

3 = -6 + b

b = 9

y = 3/2 x + 9

g(x) = 3/2 x + 9

elixir [45]

Answer: 1

Scotland

Step-by-step explanation:

In the first vote, points are:

France = 15

England = 12 + 16 = 28

Ireland = 19

2nd vote

England = 15

Scotland = 12 + 19 = 31

Ireland = 16

3rd vote

Scotland = 15 + 16 = 31

Ireland = 12

England = 19

4th vote

Ireland = 15

France = 12 + 16 + 19 = 47

At the end of everything

England = 19 + 15 + 28 = 62

France = 15 + 47 = 62

Scotland = 31 + 31 = 62

Ireland = 19 + 16 + 12 + 15 = 62

To find the Condorcet winner, the number of votes for runner over opponent (runner,opponent) is compared with the number of votes for opponent over runner (opponent,runner)  

Only Scotland has the highest (31) points twice.
