for 7 we only need Pythagoras's theorem, know it?
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]
out of curiosity.. does the above formula seem "impossible" ? or does it make sense?
[tex]c^{2}[/tex] = [tex]12^{2}[/tex] + [tex]16^{2}[/tex]
[tex]c^{2}[/tex] = 144 + 256
[tex]c^{2}[/tex] = 400
c = [tex]\sqrt{400}[/tex]
c = 20
x= 20
for 8 we do need the above list of trig functions. we want to find the Hyp x and we know an angle and the adjacent side sooo use Cos .. b/c we can see it's got those parts in it
Cos(60) = 18 / x
I'll show you the algebra we need to use to get this formula so that we can find x
A = B / x ( this is how it looks above )
x = B / A , now just put in the parts
x = 18 / Cos(60) now solve it w/ your calculator.. :P Cos(60) happens to be 1/2 so you could have done this w/o your calculator :/
x = 36

There are 10 cups placed on a table face down. Beneath each cup is one coin. Together, there are 5 quarters, 2 nickels, and 3 dimes. One cup is randomly selected, replaced, and then another cup is selected. What is the probability of getting a quarter then a nickel?
The options are
- 3/20
- 1/10
- 1/9
- 7/10
Answers
Answer:
1 / 10
Step-by-step explanation:
Prob of getting a quarter on the first draw = (5/10)
Prob of getting a nickel on the second draw = (2/10)
So......the overall probability is (5/10) (2/10) = 10 / 100 = 1 / 10

Subtraction Property of Equality
Step-by-step explanation:
Given
[tex]-x + 1 = -4[/tex]
[tex]-x = -5[/tex]
Required
State which property is used
The word that describes the operation is; subtraction property of equality.
This property states that:
if [tex]x = y[/tex] then
[tex]x - a = y - a[/tex]
So, for the given equation:
[tex]-x + 1 = -4[/tex]
When the subtraction property of equality is applied
[tex]-x + 1 - 1 = -4 - 1[/tex]
[tex]-x = -5[/tex]
So:
(a) Subtraction Property of Equality is correct

What the slope? Can someone help me
Answers
Answer:The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Answers
Answer:
Step-by-step explanation:
(+5) + (+2) = +7
If both numbers have same sign, add and the result will have the common sign
v) (-5) + (-2) = (-7)
Both numbers have 'negative sign'. So, add and the result will have the 'negative sign'
Viii) (+6) + (-3) = +3
Both numbers have different sign. So, subtract and the result will have the sign of the bigger number. Here the bigger number is '6' and its sign is 'positive'. so, the result will have positive sign
xi) (-4) + (+8) = +4
Both numbers have different sign. So, subtract and the result will have the sign of the bigger number. Here the bigger number is '8' and its sign is 'positive'. so, the result will have positive sign

How much does a t - shirt cost?
Answers
Answer:
Hat costs 4.00
T-Shirt costs 9.00
Step-by-step explanation:
Let the t-shirt be t and the hat be h
7t+h=67
5t+h=49
Equating by eliminating the h and subtracting
the two equations,
2t=18
t=9.
If t =9 in 5t + h= 49 then

Answers
Answer:

Here, [tex]x[/tex] represents temperature and [tex]y[/tex] denotes rate of chirping per minute.
Step-by-step explanation:
Let [tex]x[/tex] represents temperature and [tex]y[/tex] denotes rate of chirping per minute.
At [tex]106[/tex]°F, a certain insect chirps at a rate of [tex]67[/tex] times per minute.
Take [tex](x_1,y_1)=(106,67)[/tex]
At [tex]108[/tex]°F, they chirp [tex]83[/tex] times per minute.
Take [tex](x_2,y_2)=(108,83)[/tex]
Slope intercept form:
[tex]y-y_1=(\frac{y_2-y_1}{x_2-x_1})(x-x_1)[/tex]
[tex]y-67=(\frac{83-67}{108-106})(x-106)\\\\y-67=(\frac{83-67}{108-106})(x-106)\\\\y-67=(\frac{16}{2})(x-106)\\\\y-67=8(x-106)\\y-67=8x-848\\y=8x+67-848\\y=8x-781[/tex]

Step-by-step explanation:
in one year she will have the following
12 x 3 = 36
+ 9 given
36+9 = 45 songs in one year
if it was decreasing to 11 months or 10 months etc
Then we use this formula
Birthday + (Amount monthly x No of month)
9 + (3 x 11) = 42 in 11 months
or 9 + (3 x 10) = 39 in 10 months
