please help find the top angle
Answer:
130 degrees
Step-by-step explanation:
So u can see those little lines on two of the sides of the triangle, it means that it's congruent also meaning the same length, and if u didn't, the angles had to be the same in order for the sides to be the same length. So the other missing angle degree is also 25 degrees. A triangle is 180 degrees, so with this info:
25 + 25 + 4x + 2 = 180
4x + 52 = 180
4x = 128
x = 32, now we have x so replace the x in the equation with 32
4(32) + 2
128 + 2
130

This week is representative of how many hours Ricki will work each week during Summer Break. If she earns $9 per hour and there are 12 weeks in summer vacation, what will Ricki’s gross earnings be? Explain your reasoning. Please answer ASAAAAP
Answer:
The answer would be $18,144.
Step-by-step explanation:
First you have to figure out how many hours are in one week. 168 hours are in one week. The problem is asking us for 12 weeks. You would have to multiply 168 by 12 to see how many hours it would be. 168 times 12 is 2,016. Ricki earns $9 every hour. Next, you would have to multiply the 2,016 by 9 to give you 18,144. I hope this helps.

Where is the Y- intercept at
Answer:
(0, -2)
Step-by-step explanation:
The y-intercept is where the graph crosses through the y axis, when x is equal to 0. On this graph, the line goes through the y-axis at -2. At -2, we can also see that x=0
In general, the y-axis of a graph will always be (0, y).
What is the slope of the line that passes through the points (-4,6) and (-3,2)
Answer: m=4/7x
Step-by-step explanation:

Oceanside Bike Rental Shop charges 12 dollars plus 6 dollars an hour for renting a bike. Write an expression for the cost of renting bikes for x hours.
Answer:
[tex]y = 12 + 6x[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = 12[/tex]
[tex]Additional = 6[/tex] per hour
Required
Determine the expression for the cost in x hours
Represent the cost with y
y is calculated using the following expression
[tex]y = Base\ Amount + Additional * x[/tex]
Where x represent the number of hours.
Substitute values for the base amount of bike and the additional cost per hour
[tex]y = 12 + 6 * x[/tex]
[tex]y = 12 + 6x[/tex]
So, the expression to determine the cost of bike in x hours is: [tex]y = 12 + 6x[/tex]

Dr. Cohn is testing how long it takes for a person's body to process a new medicine. She observes that the medicine is used by the body at a constant rate. For her latest test, Dr. Cohn starts with 15 milligrams of the medicine and notes that 12.6 milligrams remain unused after 1 hour. Which equation could Dr. Cohn use to solve for p, the percentage of the medicine that is used in 1 hour? A. p100=12.615 B. p100=2.415 C. p15=1002.4 D. p15=10012.6
Answer:
the options were not copied correctly, option B could be correct but it is missing the division signs:
B. p / 100 = 2.4 / 15
the percentage of medicine used in 1 hour:
p / 100 = (15 - 12.6) / 15 = 2.4 / 15
p / 100 = 0.16
p = 0.16 x 100 = 16%
another option could be C but it would be missing the multiplication signs:
C. p x 15 = 100 x 2.4
p x 15 = 240
p = 240 / 15 = 16%
Rachel multiplied each side of ≥x greater than or equal to 2 by 3. She wrote the result as ≤3 x less than or equal to 6 . Explain the error Rachel made.
Answer:
Rachel's error is in the inequality sign
Step-by-step explanation:
Given
[tex]x \geq 2[/tex]
Required
Determine the error in Rachel's workings
From the question, we understand that both sides of the inequality were multiplied by 3
i.e.
[tex]3 * x \geq 2 * 3[/tex]
This gives
[tex]3 x \geq 6[/tex]
Comparing this to Rachel's result: [tex]3 x \leq 6[/tex]
We can conclude that Rachel's error is in the inequality sign.
The sign of an inequality will only change is it is being multiplied or divided by a negative number; otherwise, the sign remains unchanged

Carlos pays $25 for skis and borrows the remaining amount. The loan payments are $75 every 3 months for 1/1/2 years. The interest rate is 16.2%/a compounded quarterly. What was the selling price of the skis?
Answer:
$417.52
Step-by-step explanation:
Present value of annuity = P * {1-[1/(1+r)^n]/r}
P =Periodic payment i.e. 75
r = rate of interest per period i.e. 16.2% /4 = 4.05% or 0.0405
n =no. of compounding period i.e. 1.50*4 =6
Present value of annuity = Loan amount
Present value of annuity = 75 * {1-[1/(1+0.0405)^6]/0.0405}
Present value of annuity = 75 * {1-[1/(1.0405)^6]/0.0405}
Present value of annuity = 75 * {1-[1/1.268973)/0.0405}
Present value of annuity = 75 * (1-0.78804)/0.0405
Present value of annuity = 75 * (0.21196/0.0405)
Present value of annuity = 75 * 5.23361
Present value of annuity = 392.52
Loan amount = $392.52
Selling price = $392.52 + $25.00
Selling price = $417.52
Thus, the selling price of the skis is $417.52
i need help what is w-8=32
Answer:
w=40
Step-by-step explanation:
w=40 because when you subtract 40-8 the sum is 32 so W=40
w-8=32
------------------------------------------------------------------------------------------------------
add 8 to -8, and 32.
8 and -8 will cancel out. 32 and 8 will increase though. So, it should be:
w=40
