Answer:
9) (68 + 160)/2 = 114°
10) 80/2 = 40°
11) 105 x 2 = 210°
12) 80 x 2 = 160°
13) (360 - 180 - 108)/2 = 36°
14) (360 - 69 - 95)/2 = 98°
Find all the missing sides and angles of this triangle,

The measurement of angle A
A A=
The length of side BC
The length of side AC-
Answer:
See solutions below
Step-by-step explanation:
From the given diagram;
AC = opposite
AB = 7 = hypotenuse
Angle of elevation = 70 degrees
Using SOH CAH TOA
Sin theta = opp/hyp
Sin theta = AC/AB
Sin 70 = AC/7
AC = 7sin70
AC = 7(0.9397)
AC = 6.58
Similarly
tan 70 = AC/BC
tan 70 = 6.58/BC
BC = 6.58/tan70
BC = 6.58/2.7475
BC = 2.39
tan m<A = BC/AC
tanm<A = 2.39/6.58
tan m<A = 0.3632
m<A = 19.96degrees

May someone help me please. Solve for x and then find the indicated length. Pleaseee
Answer:
16
Step-by-step explanation:
3x + 4 = x + 12 [The straight line on the segments AB and BC indicate that they are the same length]
2x = 8 [Subtract x and 8 from both sides]
x = 4 [Divide both sides by two]
Length AB is equal to (3x + 4) as indicated by the diagram. Substituting x = 4, (3 * 4) + 4 = 16

Step-by-step explanation:
Is j+j+j+j and j with the power of four equivalent?
Answer:
No, they are not equivalent.
Step-by-step explanation:
j + j + j + j = 4j
j^4
Let's say j = 2
4j = 8
j^4 = 16
Answer:
NO
Step-by-step explanation:
j+j+j+j
remember multiplication is repeated addition!
j+j+j+j = 4j
THIS IS DIFFERENT! powers are repeated MULTIPLICATION.
j^4 = j to the power of 4 = j * j * j * j, NOT j+j+j+j !!!!!

Use elimination to solve for x and y:
9x - 2y = 46
x + 2y = 14
Answer:
(6, 4 )
Step-by-step explanation:
Given the 2 equations
9x - 2y = 46 → (1)
x + 2y = 14 → (2)
Adding the 2 equations term by term will eliminate the y- term
10x + 0 = 60
10x = 60 ( divide both sides by 10 )
x = 6
Substitute x = 6 into either of the 2 equations and solve for y
Substituting into (2)
6 + 2y = 14 ( subtract 6 from both sides )
2y = 8 ( divide both sides by 2 )
y = 4
solution is (6, 4 )
A drug store chain provides an app to its customers to track their shopping habits. One statistic the app
tracks is the amount of money the customer saves by purchasing sale items. The company's sales
team pulls data from the previous year for a random sample of 50 customers. They find that the
mean amount of money saved by these customers in the previous year is $154 with a standard
deviation of $26.
(a) Construct a 99% confidence interval for the true mean amount of money saved by all customers
in the previous year by purchasing sale items.
(b) The sales team would like to repeat this study with the goal of obtaining a smaller margin of
error. Propose two changes that would decrease the margin of error. What are potential
drawbacks if those changes are implemented?
Answer:
a) CI ( 99% ) = ( 145,45 : 162,55)
b) b) In order to decrease the MOE the sales team has to increase the sample or decrease de 99% of the CI let´s say to 95 % but in that case
you will increase de error type I
Step-by-step explanation:
a) CI = 99 % α = 1% α = 0,01
From z-table z(c) ≈ - 2,325 |z(c)| ≈ 2,325
CI = ( μ₀ ± z(c) * σ/√n )
CI = ( 154 - (2,325) * 26/√50 ; 154 + (2,325) * 26/√50 )
CI = ( 154 - 8,55 ; 154 + 8,55
CI ( 99% ) = ( 145,45 : 162,55)
b) In order to decrease the MOE the sales team has to increase the sample or decrease de 99% of the CI let´s say to 95 % but in that case
you will increase de error type I

16. You decide to drop a penny off the top of the Willis Tower (fromerly the Sears Tower) in Chicago, IL. The
height of the penny (in feet) can be represented by the equation h= -16t2 + 1451 where t is time (in seconds).
a) How long will it take for the penny to hit the ground? Show any work that leads to your answer.
Answer:
9.5 seconds.
Step-by-step explanation:
We know that the equation that represents the height of the penny as a function of time is:
h(t) = -16*t^2 + 1451
Where the height is in ft, and the time is in seconds.
a) We want to know how long takes the penny to hit the ground.
Well, the penny will hit the ground when its height is equal to zero.
Then we need to solve for t:
h(t) = 0 = -16*t^2 + 1451
0 = -16*t^2 + 1451
16*t^2 = 1451
t^2 = 1451/16 = 90.7
t = √90.7 = 9.5
This means that it takes 9.5 seconds to hit the ground.
Answer:9.5 seconds

Find the surface area (help me please ╥﹏╥ )
Answer:
100
Step-by-step explanation:
Add all of the inches together including the parts you don't see.
one side is 9 inches. there are 8 sides. so 9x8. One side in the box is 7 inches. there are 4 sides. so 7x4. 9x8 + 7x4 is equal to 72 + 28.
72 + 28=100
