Answer:
B. Obtuse angle
Step-by-step explanation:
Remember that a right angle is 90 degrees and would be like the edge of a square or rectangle going completely vertical. An obtuse angle is larger than 90 degrees so the vertex or point where both lines connect would have both lines farther apart. An acute angle is smaller than a 90-degree angle and is closer to touching the lines (a tip for remembering acute angles could be "a-cute angle" or a smaller cute angle). Hope this helps!

Which expression is equivalent to (-7-4i)(6+7i)?
Answer:
Step-by-step explanation:
-14 - 73 i
Answer:
-28i^2-73i-42
Step-by-step explanation:
(−7)(6)+(−7)(7i)+(−4x)(6)+(−4i)(7i)
= −42−49i−24i−28i^2
= -28i^2-73i-42

Answer:
C (Lake Depth Answer)
Step-by-step explanation:
Here we want to find the math that ends up with 0.
The stock starts with 12$, but loses 16$.
That's -4$ total, not 0.
The ion starts with 19 protons, and 18 electrons. Protons are postive charges, electrons are negative.
This leaves us with 1 proton, not 0.
The lake depth increases by 6 inches, but evaporates 6.
This leaves us back where we started, with 0.
Ahmed spends 25$, but earns 30$.
This leaves us with $5, not 0.

you have 10 eggs you crack 2 cook 2 and eat 2 how many eggs do you have left?
Answer:
Wouldn't it be 8?
Step-by-step explanation:
You crack 2 eggs and cook them, then eat them. If we cracked 2 eggs, cooked 2 different eggs, and ate 2 different eggs, that doesn't make sense.
Answer:
8
Step-by-step explanation: you can crack, cook, and eat with 1 egg
so if you cracked 2 cooked 2 and ate 2, it means that you only used 2
8p+3=5p+9
Please solve with work I’ve gotten it wrong 9 times
p= 2
Step-by-step explanation:
1. subtract 3 from 3 and 9
2. subract 5p from 8p and 5p
3. it is now 3p = 6
4 divide both sides by 3
5. 6/3 is 2 so 2 =p
What is the value of the expression below 64 5/6
Answer:
[tex]64\dfrac{5}{6}=\dfrac{389}{6}[/tex]
Step-by-step explanation:
We need to find the value of the expression :
[tex]64\dfrac{5}{6}[/tex]
It is in the form of a mixed fraction. We can simplify it as follows :
[tex]64\dfrac{5}{6}=\dfrac{64\times 6+5}{6}\\\\=\dfrac{389}{6}[/tex]
Hence, the value of the given expression is [tex]\dfrac{389}{6}[/tex].

Solve each system by graphing. (REAL GRAPH PAPER ONLY)
Answer:
Slope with Y intercepts and going down/ up from there
Step-by-step explanation:
I dont have graph paper, but the B part is Y intercept. That Means that the 2nd number is where the line intercepts with Y axis. The Y axis for 1 is Y=-1, with no slope meaning its a straight line with no slope. It just goes through -1 on Y axis horizontally. On number one for the second equation, 2 is the Y intercept for the other line, and the line has a rise and run of 3/1, meaning it goes up 3 on the positive side of the x axis, and it goes to the side one. Hope this made a little sense. I learned this a few weeks ago in my algebra class.

HELLLLPPPP MEEE PLEASE AND THANK YOU
Step-by-step explanation:
180° = m<A + m<B + m<C
180° = 45° +60° + m<C
180° = 105° + m<C
m<C = 180° - 105 °
m<C = 75°
Find the zero of the function.
f(x)= 4x^2– 12x+9
Answer:
The zero is x = 3/2 = 1.5
Step-by-step explanation:
We recognize that the trinomial 4 x^2 - 12 x + 9 is a perfect square trinomial, which comes from the following squared binomial:
(2 x - 3)^2
Therefore, the zeros are the x-values that verify the following:
(2 x - 3)^2= 0
that is (2 x - 3) = 0 and solving for "x":
2 x = 3
x = 3 / 2
x = 1.5
if you dont know what 3x4= its 12

A typical tip in a restaurant is 15% of the total bill. If the bill is $100, what would the typical tip be
Answer:
15 dollars
Step-by-step explanation:

Total Bill = 100 + 15/100 * 100
Total Bill = 115
So the tip is 15 dollars.
A company that makes cola drinks states that the mean caffeine content per 12-ounce bottle of cola 40 milligrams. You want to test this claim. During your tests, you find that a random sample of thirty 12-ounce bottles of cola has a mean caffeine content of 39.2 milligrams. Assume the population is normally distributed with a standard deviation of 7.5 milligrams. At α=0.01, can you reject the company’s claim
Answer:
Claim cannot be rejected
Step-by-step explanation:
We solve this by using hypothesis testing
H0: mean = 40
H1: mean ≠ 40
We have samples of 30, but we were not gives the population standard deviation. We used the t distribution
T score = 39.2-40/(7.5/√30)
= -0.5842
Degree of freedom = 30-1 = 29
Then p value = 0.5636
In conclusion, we fail to reject the null hypothesis since 0.5636 > 0.01 significance level.
So company's claim cannot be rejected

Ok...
what exactly do you need help with?
Answer:
help with what lol
Step-by-step explanation:
Given the formula A = P(1 + )". compute A (rounded to two decimal places) if P = 10,000,7
= 0.08, k = 2, and n = 12.
A 124,800.00
B 16,010.32
C 25,181.70
D 129,600.00
30.32
Answer:
A = 16010.32
Step-by-step explanation:
Given that,
[tex]A=P(1+\dfrac{r}{k})^n[/tex]
Put P = 10,000, r = 0.08, k = 2 and n = 12 in the above formula to find A.
[tex]A=10,000(1+\dfrac{0.08}{2})^{12}\\\\=10,000\times (1.04)^{12}\\\\=16,010.32[/tex]
So, the value of A is 16010.32. Hence, the correct option is (B).
