Can someone pls help me with this
Answer:
4
Step-by-step explanation:
If you graphed it out you would see that the rise/run would be 4 over 1 which is also 4. On this table, you can see that the x is going up by 2 and the y is going up by 8 and 8/2 is also the same as 4/1 or 4 (rise/run = y/x).

Answer:
The slope is [tex] \frac{3}{8} [/tex].
Step-by-step explanation:
Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆Just plug in.
[tex]m = \frac{ - 7 - ( - 10)}{0 - ( - 8)} = \frac{3}{8} [/tex]

Answer:
urdykdgjjdtdgdmgkgdzkyjt
Answer:
1. z=kxy
2. 36=k(3)(2)
k=6 is the answer
3. 2=k(4)(3)
k= -6 is the answer
z=kxy z=(-6)(8)(6)
z= -288 is the answer
you always remember that the formula we should use is z=kxy
If 11 yards of carpet weighs 240 pounds, which formula can be used to determine x, how much 17 yards of carpet weighs?
Answer:
cross multiplication
Step-by-step explanation:
[tex]\frac{11}{240}[/tex] x [tex]\frac{17}{x}[/tex]
[yards/weight x yards/unknown weight]
11x = 4080
x = 370.9 or 371 pounds
Solve 11x - 6 = 10.5
Answer:x= 1.5
Step-by-step explanation:
I think
Answer:
X=1.5
Steps:
11x-6=10.5
11x=16.5
x=1.5
There are 12 green,22 white, 12 purple and 4 blue gum balls in the gum all machine what is the probability of getting white gum all write the probability as a percent
Answer: If you add all of these numbers of gumballs up you get 50. Since there is 50 gumballs,and 100 percent of that amount has to be filled,then you must make each gumball worth 2 percent. (12x2)+(22x2)+(12x2)+(4x2)=100
Green percent of getting=24 percent
Purple percent of getting=24 percent
Blue percent of getting=8 percent
White percent of getting=44 percent
The percent of getting a White gum is 44 percent.

Given: sin(A) = 4/5, pi/2 < A < pi and sin(B) = -2root5/5, pi < B < 3pi/2 What is the value of cos(A – B)?
Answer:
-√5/5
Step-by-step explanation:
Given the following
sin(A) = 4/5
sinB - -2√5/5
SinA = 4/5 = opp/hyp
We can get cosA
opposite = 4
hypotenuse = 5
Adj = √5²-4² (pythagoras theorem)
Adj = √25-16
Adj = √9
Adj = 3
Cos A = Adj/hyp
Cos A = 3/5
Also
Sin B = -2√5/5 = opp/hyp
opposite = -2√5
hypotenuse = 5
Adj = √5²-(2√5)² (pythagoras theorem)
Adj = √25-20
Adj = √5
Cos B = Adj/hyp
Cos B = √5/5
Evaluate cos (A-B)
cos (A-B) = cosAcosB + sinAsinB
cos (A-B) = 3/5(√5/5)+4/5(-2√5/5)
cos (A-B) = 3√5/25 - 8√5/25
cos (A-B) = -5√5/25
cos (A-B) = -√5/5
Hence the value of cos (A-B) is -√5/5

if $850 grows to $1125 at an interest rate of 12.6% compounded continuously, how long has the money been in the account?
Answer:
22 years approx.
Step-by-step explanation:
Step one
Given data
Principal P= $850
final amount A= $1125
rate r= 12.6%
Calculate time, solve for t
t = ln(A/P) / r
Step two:
Substitute
t= ln (1125/850)/0.0126
t=ln 1.32/0.0126
t= 0.277/0.0126
t=21.9
t= 22 years approx.
