What is the missing length?
6 mi
t
area =
60 mi2
Answer:
10 mi
Step-by-step explanation:
6mi x t = 60mi^2
this is basically
6 x t = 60
divide 6 to both sides
t = 10
In ΔNOP, n = 800 inches, ∠P=97° and ∠N=32°. Find the length of o, to the nearest inch.
9514 1404 393
Answer:
1173 in
Step-by-step explanation:
The measure of angle O is ...
O = 180° -N -P = 180° -32° -97° = 51°
The law of sines tells you ...
o/sin(O) = n/sin(N)
o = n·sin(O)/sin(N) = (800 in)·sin(51°)/sin(32°)
o ≈ 1173 in

Answer:
The last one: 70/100 = x/80
And 56 free throws.
Explanation:
70% is 70 out of 100. And if the player is free throwing a total of 80 times, then 80 is 100% of the free throws. Both of the values that represent 100% are the denominators in the fractions.
[tex]\frac{70}{100} = \frac{x}{80}[/tex]
The equations are equal, and whatever you do to the bottom, you have to do to the top. 100 was multiplied by 4/5 to get 80. So 70 is multiplied by 4/5 to get x.
4/5 * 70 is 56
Find the measure of the indicated angle.

Answer: what are you supposed to find out?
Step-by-step explanation:
if -2x+ y =6 and -7x-4y=-8 are true equations what would the value of -9x-3y
Answer:
[tex]-\frac{106}{5} or -21.2[/tex]
Step-by-step explanation:
First we would have to get x and y-values by solving systems of equations:
isolate one of the variable from any of the first 2 equations given:
-2x+ y =6 would be y = 2x + 6 when y is isolated.
now plug this equation in for the y given in the second equation:
-7x -4(2x + 6) = -8
Now solve to get the x-value,
-7x - 8x - 24 = -8
-15x - 24 = -8
-15x = 16
x = [tex]-\frac{16}{15}[/tex] or -1.06
To solve for y-value, substitute the gotten x-value in any of the 2 equations and solve:
y = 2([tex]-\frac{16}{15}[/tex]) + 6
y = [tex]\frac{58}{15}[/tex] or 3.86
Now that we have the x and y-values, substitute them in for the 3 equation given:
-9([tex]-\frac{16}{15}[/tex]) -3( [tex]\frac{58}{15}[/tex])
=> [tex]-\frac{106}{5}[/tex] or -21.2 = Final Answer
Hope this helps!

a can do a piece of work in 10 days, B in 12 days and C in 15 days how long will it take them it together to complete it.
Answer:

A can do a piece of work in 10 days, B in 12 days and C in 15 days. How long will it take them it together to complete it ?
Explanation -:We observe here that A can do the work in 10 days; B can do the same work in 12 days whereas C can do the same work in 15 days. We are asked to calculate how much time will it take if three of them will work together.
We will solve this problem with traditional method.
Let us solve the question.
[tex] \small\pmb{ A's \: 1 \: day's \: work = \dfrac{1}{10}}[/tex]
[tex] \small\pmb{ B's \: 1 \: day's \: work = \dfrac{1}{12}}[/tex]
[tex] \small\pmb{ C's \: 1 \: day's \: work = \dfrac{1}{15}}[/tex]
[tex] \small\sf{ (A + B + C)'s \: 1 \: day's \: work = \frak {\dfrac{1}{10}+\dfrac{1}{12} + \dfrac{1}{15}}}[/tex]
L.C.M of 10, 12 and 15 is 60[tex] \longrightarrow \small\frak{ \dfrac{6 + 5 + 4}{60} } [/tex]
[tex] \longrightarrow \small\frak{ \dfrac{15}{60} = \dfrac{1}{4} } [/tex]
Hence A,B and C can finish the work in 4 days.[tex] \rule{40mm}{3pt}[/tex]

If a person can complete a work in x days, then in 1 day the person does 1/x of the work.If a person can complete 1/x of the work in 1 day, then the person requires x days to complete the work.If some persons work together to do a piece of work, then the money paid to them is divided among them in ratio of their one day's work[tex] \overline{ \underline{ \rule{72mm}{4pt}}}[/tex]

The sum of the fifth and sixth term of an AP is 30.If the third term is 5.Find the first term.
Answer:
The first term is -3.
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between two consecutive terms is always the same, and it is called common difference d.
The nth term is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term.
If we have the mth term instead of the first, we have:
[tex]a_n = a_m + (n-m)d[/tex]
We have the third term, and need the fifth and the sixth:
So we write both the fifth and the sixth in function of the third, then:
[tex]a_5 = a_3 + 2d = 5 + 2d[/tex]
[tex]a_6 = a_3 + 3d = 5 + 3d[/tex]
The sum of the fifth and sixth term of an AP is 30
We use this to find [tex]d[/tex]. So
[tex]a_5 + a_6 = 30[/tex]
[tex]5 + 2d + 5 + 3d = 30[/tex]
[tex]5d + 10 = 30[/tex]
[tex]5d = 20[/tex]
[tex]d = \frac{20}{5} = 4[/tex]
First term:
The third term is:
[tex]a_3 = a_1 + 2d[/tex]
Since [tex]a_3 = 5, d = 4[/tex]
[tex]a_1 = a_3 - 2d = 5 - 8 = -3[/tex]
The first term is -3.

Option C is the only table that represents a data set that could be fit to a normal distribution curve.
In a normal distribution, the data is symmetrically distributed around the mean, and the percentages decrease as you move away from the mean.
Option C exhibits this characteristic, where the percentages are highest at the mean values (5, 6, 9, 10) and decrease as you move away from the mean.
Where as the tables in options A, B, and D do not exhibit the characteristics of a normal distribution as the percentages do not decrease symmetrically away from the mean values.
