Answer:
m∠ADB = 35°
Step-by-step explanation:
From the figure attached,
∠ACB and ∠ADB are the angles subtended by the same arc AB.
m(arc AB) = (5x - 30)°
m∠ACB = (x + 15)°
Since, "measure of an arc is double of the measure of the angle subtended by the arc at the circumference"
m(arc AB) = 2(m∠ACB)
(5x - 30) = 2(x + 15)
5x - 30 = 2x + 30
5x - 2x = 30 + 30
3x = 60
x = 20
By using theorem,
"Angles subtended by the same arc in the same segment of a circle are equal in measure"
Therefore, m∠ACB = m∠ADB
Since, m∠ACB = (x + 15)°
= 20 + 15
= 35°
m∠ADB = 35°

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)

What is Permutation and Combination ?A permutation is an act of arranging the objects or numbers in order. Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.
A bag contains one green ball, one yellow ball, one red ball, and one blue ball.
Jerome picks a ball from the bag, replaces it, and then picks another ball.
Order matters since the ball is being replaced each time.
This is all the possible combinations to take 2 balls with replacement,
GY YY RY BY GR YR RR BR GB YB RB BB GG YG RG BG
For the first missing blank , RR, RB, and RG are listed and the only other combination when choosing a red first would be to pick a yellow, so RY.

Una recta atraviesa el punto (8, -1) y tiene una pendiente igual a 5/4.
Escribir una ecuación en forma pendiente intersección para esta recta.
Answer:
y = (5/4)x - 11
Step-by-step explanation:
Use y = mx + b as your starting point. This becomes y = (5/4)x + b.
Substitute 8 for x and -1 for y and solve for b:
-1 = (5/4)(8) + b, or
-1 = 10 + b.
Then b must be -11, and the desired equation is
y = (5/4)x - 11

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

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]

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

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°Which statement is not true about histograms

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.
