C. 128°Step-by-step explanation:
Here,
<BAC + <BAE = 180° [Since supplementary angles]
=> 52° + <BAE = 180°
=> <BAE = 180° -52°
=> <BAE = 128° (Ans)

simplify 2/3(6x−1/6)+3x
Answer:
7x - 1/9
Step-by-step explanation:
2/3 (6x - 1/6) + 3x
12x/3 - 2/18 + 3x
4x - 1/9 + 3x
7x - 1/9
After simplifying, the value of expression is,
⇒ 7x - 1/9
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ 2/3 (6x - 1/6) + 3x
Now, We can solve the expression as;
⇒ 2/3 (6x - 1/6) + 3x
⇒ 2/3 × 6x - 2/3 × 1/6 + 3x
⇒ 4x - 1/9 + 3x
⇒ 7x - 1/9

Question 15 of 40
For which sample size (n) and sample proportion () can a normal curve be
used to approximate the sampling distribution?
O A. n = 28; = 0.3
O B. n = 28; p = 0.9
O c. n = 32; p = 0.4
O D. n = 32; p = 0.2
Answer:
Option C: n = 32; p^ = 0.4
Step-by-step explanation:
The normal curve can be used in this case if; np ≥ 10 or n(1 - p) ≥ 10
A) For n = 28 and p = 0.3;
np = 28 × 0.3 = 8.4 < 10
Thus, it can't be used.
B) For n = 28 and p = 0.9;
np = 28 × 0.9 = 25.2 > 10 Ok
n(1 - p) = 28(1 - 0.9) = 2.8 Not Ok
Thus, it can't be used
C) For n = 32 and p = 0.4
np = 32 × 0.4 = 12.8 > 10 Ok
n(1 - p) = 32(1 - 0.4) = 19.2 > 10 Ok
Thus, it can be used
D) For n = 32 and p = 0.2
np = 32 × 0.2 = 6.4 < 10 Not Ok
Thus it can't be used.

29 / x = tan 65x = 29 / tan 65 x = 13.5#2
x / 3 = tan 70x = 3 tan 70x = 8.2#3
15 / x = tan 40x = 15 / tan 40x = 17.9Solve the right triangle. See image below.
Hi there! You still remember the Pythagorean Theorem, right? It's useful when it comes to finding a missing leg or side of a right triangle. If you forget then here it is:
[tex] \large \boxed{ {a}^{2} + {b}^{2} = {c}^{2} }[/tex]
Define c = hypotenuse while a and b can be both adjacent and opposite (because a²+b²=b²+a² via addition property)
Since we are missing the adjacent side. Thus,
We define a = 6 and c = 14.
[tex] \large{ {6}^{2} + {b}^{2} = {14}^{2} } \\ \large{36 + {b}^{2} = 196} \\ \large{ {b}^{2} = 196 - 36} \\ \large{ {b}^{2} = 160} \\ \large{ b = \sqrt{160} \longrightarrow \boxed{b = 4 \sqrt{10} }}[/tex]
Put the value of b in a calculator then round to the nearest tenth and get 12.6
Thus, the value of b ≈ 12.6
Next we are going to find the angle in degree. We now know that b ≈ 12.6 or 4sqrt(10)
We can find the value of angle A by using tan or sin but I will use sin instead. Recall the sine ratio which is opposite to hypotenuse. Thus,
[tex] \large{sinA = \frac{6}{14} }[/tex]
Use arcsin(6/14) and put it in calculator.
Then put the decimal value of arcsin in sin and convert in degree form which we should get 24. 555°. Round to the nearest whole number and we get 25°
Thus, the angle A is 25°
Next is we are finding the value of angle B. We aren't going to use any formula or equation. Recall that three angles add up to 180°.
Thus, 25° + 90° + x = 180°
90° comes from a right angle.
115+x = 180
x = 180-115
x = 65°
Thus, the angle B is 65°
Answer
b ≈ 12.6 or 4sqrt(10)angle A = 25°angle B = 65°Determine if the two triangles are congruent

1. What is the space inside an object called? What type of objects have volume?
2. Compare the slopes of parallel lines and perpendicular lines.
3. Explain the difference between a secant and a tangent.
Answer:
1. Volume measured in Cubic units (to the third power), Only 3-D objects have volume.
2. Parallel lines have the same slope and will never intersect. The slope of perpendicular lines are the negative reciprocals of each other, they will intersect a 90 degrees
3. Secant is 1/cosX (1 over cosine of x), tangent is sinX/cosX(sine of x over cosine of x)

Step-by-step explanation:
Susan completed a 26-mile rollerblade marathon in 2.5 hours. If Susan skated at a constant rate, how fast was she skating? A. 10.4 mph B. 8.3 mph C. 6.5 mph D. 4.7 mph
Answer:
A. 10.4 mph
Step-by-step explanation:
26÷2.5=10.4
Double checking your answer:
If she does 10.4 miles in an hour, she can get 20.8 in two hours
then you add half of how much she can go in an hour which is 5.2 (10.4÷2)
you add it together, and you will get 26 miles in total
(20.8+5.2=26)

Explain which properties you would use to fully expand (the problem in the screenshot)
Answer:
Firs property used : Quotient Property
[tex]log_b(\frac{X}{Y} ) = log_bX -log_bY[/tex]
[tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = log_b(\sqrt[3]{x}) - log_b(36y^2)[/tex]
Second property used : Product Property
[tex]log_b(XY) = log_bX + log_b Y[/tex]
[tex]log_b(\sqrt[3]{x}) - log_b(36y^2) = (log_b(\sqrt[3]{x}) - [log_b36 + log_by^2)[/tex]
Third property used : Power Property
[tex]log_b \sqrt[n]{X} = log_b(X)^{\frac{1}{n}} = \frac{1}{n} log_b X[/tex]
[tex](log_b(\sqrt[3]{x}) - [log_b6^2 + log_by^2) = \frac{1}{3} log_bx - 2log_b 6 - 2log_by[/tex]
Fully expanded form:
[tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = \frac{1}{3} log_b x-2log_b6-2log_by[/tex]

Which of the following equations has both -2 and 2 as possible values of b?
A. b2 = 4
B. b3 = 8
C. None of the Above
The equation that has the possible values of b is b² = 4.
How to find the equation that has possible vale of -2 and 2?The equation that has the possible value of b as -2 and 2 are as follows;
b² = 4
-2² = 4 and 2² = 4 (This is true)
b³ = 8
-2³ = -8 and 2³ = 8(This is false)
Therefore, the equation that has the possible values of b is b² = 4.

cashiers at 10:00 am, how many would there be at 4:00 pm?
Picture included at the top. 6th grade math
Answer:
4 and 5
Step-by-step explanation:
So alternate means there's on different sides of the one line that cuts through both lines, so that would be 1 and 8, 2 and 7, 3 and 6, and 4 and 5. But interior means that it's on the inside, so that would be 3 and 6, and 4 and 5, so 4 and 5 is your answer

What is y=4x-29
x+y=1
MUST SHOW WORK!!
Answer:
Hope this helps!! (x,y)=(6,-5)
Answer:
y=-5
x=6
Step-by-step explanation:
substitute y=4x -29 into the equation x+y=1.
x+ 4x-29 = 1
combine like terms
5x-29=1
add 29 to both sides
5x=30
divide by 5
x=6
plug 6 into x in the original equation
y=4(6) - 29
y=24-29
y= -5
