Answer:
x=85
Step-by-step explanation:
let's angle c be x
39+56+x=180
95+x=180
x=180-95
x=85
Answer:
85 degrees
Step-by-step explanation:
In similar triangles, corresponding angles are congruent, or have the same measure.
Therefore, angle B must also be 56 degrees. In a triangle, there are 180 degrees.
A+b+c=180
39+56+c=180
c=85 degrees.

Maria is planning a party for her friends. Sally's Kitchen charges a fee of
$60 to set up and then $12 per plate. Jimmy's BBQ and Steak charges a fee
of $100 to set up and then $10 per plate. At how many plates will the cost
of Sally's and Jimmy's be the same? How many plates will the cost of
Sally's and Jimmy's be the same? *
Answer:
20 Plates
Step-by-step explanation:
Given that :
Sally's kitchen :
Setup cost = $60
Cost per plate = $12
Jimmy's BBQ :
Setup cost = $100
Cost per plate = $10
Let number of plates = x
Equate both and solve for x :
Sally's kitchen = Jimmy's BBQ
60 + 12x = 100 + 10x
12x - 10x = 100 - 60
2x = 40
x = 40/2
x = 20
20 plates
What is 0.0492 in standard form?
Answer: How to write numbers in standard form:
Write the first number 8.

Answer:
x = 14
Step-by-step explanation:
First put it into slope intercept form
20 = 2x - 8
Move the variable to the left hand side and change its symbol
-2x + 20 = -8
Move the constant to the right hand side and change its symbol
-2x = -8 - 20
Calculate the difference
-2x = -28
Divide both sides of the equation by -2
x = 14
Solution
X = 14

2. Lorena is trying to choose between two different savings accounts at H-Town Bank. She will deposit $3,500 dollars and will leave the money in the account for 12 years. There will be no additional money deposited or withdrawn from the account.
Answer:
First of all, this question is not complete. So, we will be hypothetically create two accounts and try to choose the one with the greater profit.
Choice 1 = X = Final Amount after 12 years = $5600
Choice 2 = Y = Final Amount after 12 years = $6285.50
Hence, Lorena should choose choice 2, as it gives more profit over than choice 1.
Step-by-step explanation:
First of all, this question is not complete. So, we will be hypothetically create two accounts and try to choose the one with the greater profit.
Initial Deposit Amount = $3500
Time period = 12 years
Let's Suppose Lorena has two X and Y choices of accounts at H-town Bank.
X = simple interest of 5% over the initial amount for 12 years.
Y = Compound interest 5% over the initial amount for 12 years.
Solution:
Let's calculate the profit for choice 1 = X
Simple interest = 5%
Initial amount = $3500
Time period = 12 years
Formula = A = P (1 + rt)
where, A = Final amount after 12 years
t = time period in years = 12
P = initial amount to be deposited = $3500
r = annual interest rate = 5%
Plug in the values to get the total amount.
A = 3500(1+0.05x12)
A = $5600 = final amount Lorena will get after 12 years.
Let's calculate the profit for choice 2 = Y
Compound interest = 5%
Initial amount = $3500
Time period = 12 years
Formula = A = P [tex](\frac{r}{n} + 1)^{nt}[/tex]
where,
A = Final amount after 12 years
t = time period in years = 12
P = initial amount to be deposited = $3500
r = annual interest rate = 5%
n = number of times interest rate is applied or compounded. = 12
Plug in the values to get the total amount.
A = P [tex](\frac{r}{n} + 1)^{nt}[/tex]
A = $6285.50
Hence, Lorena should choose choice 2, as it gives more profit over than choice 1.
The half-life of the element radon (Rn86) is 3.8 days. In a sample originally containing 1 gram of radon, the amount of left over days is given by the model () = (0.5)t/3.8 a) How much radon will be present after 7.6 days? b) How much radon will be present after 10 days?
Answer:
a.0.25 g
b.0.16 g
Step-by-step explanation:
We are given that
Half-life of the element radon=3.8 days
Mass of sample of radon=1 g
The amount of radon left after t days is given by
[tex]A(t)=(0.5)^{\frac{t}{3.8}}[/tex]
a.
We have to find the amount of radon left after 7.6 days.
Substitute t=7.6 in the equation
Then, we get
[tex]A(7.6)=(0.5)^{\frac{7.6}{3.8}}[/tex]
[tex]A(7.6)=0.25 g[/tex]
Hence, the amount of radon will be present after 7.6 days=0.25 g
b. We have to find the amount of radon left after 10 days.
Substitute t=10 in the equation
Then, we get
[tex]A(10)=(0.5)^{\frac{10}{3.8}}[/tex]
[tex]A(10)=0.16g[/tex]
Hence, the amount of radon will be present after 10 days=0.16 g

Sonya made a graph showing the first ten minutes of her drive to the movies.
A graph with time on the x-axis and speed on the y-axis. The graph increases, increases rapidly, and then remains constant.
Which description is the best interpretation of the graph?
Sonya left her house and accelerated as she drove toward the highway entrance. She increased her speed as she drove up the ramp to the highway and then drove a constant speed on the highway.
Sonya backed out of her driveway at a constant speed and then accelerated until she reached the street where the movie was playing. She stopped the car.
Sonya drove down her driveway at a constant speed until she reached the street. She turned and drove down the street at a constant speed. Her car went slower as she drove up a hill. At the top of the hill she drove into the parking lot of the movie theater.
Sonya accelerated as she drove down her driveway. She accelerated on the street on her way to the highway entrance. She waited for a red light, then accelerated onto the highway.
Answer:
A
Step-by-step explanation:
A. because the first point shows her acceleration and you can see her speed increasing when she hits the second point, so we can say that see accelerated up the ramp and after it hits the third point her speed becomes constant all the way when she reached the highway
