Step-by-step explanation:
If ∠P measures 27°, ∠R measures 135°, and p equals 9.5, then which length can be found using the Law of Sines?
Answer:
The length r can be found using the Law of sines.
Length r = 14.8
Step-by-step explanation:
The length r can be found using the Law of sines.
The formula for the Law of Sines states that:
a/Sin A = b/ Sin B
In the above question,
∠P = 27°
∠R = 135°
p = 9.5
r = ????
The formula =
p/Sin P = r/Sin R
9.5/Sin 27° = r/Sin 135°
Cross Multiply
r × Sin 27° = 9.5 × Sin 135°
r = 9.5 × Sin 135°/Sin 27°
r = 14.7966
Approximately Length r = 14.8
Rita is 8 years older than Fati. If Fati is 15 years now, how old was Rita 3 years ago
Answer:
Rita is 20 years old
Step-by-step explanation:
If you add 8 years to Fati's age, (15+8), you get 23. That is Rita's age right now. Now subtract 3 from 23. You get 20. So Rita is 20 years old.

3x + 5 = 2x + 2 -(x-3) Pls show work too, thanks :)
Answer:
X=0
Step-by-step explanation:
1.Remove the parentheses
3x + 5 = 2x + 2 -(x-3) -> 3x+5=2x+2-x+3
2.Combine like terms
3x+5=2x+2-x+3 -> 3x+5=x+5
3.Cancel Equal Terms
3x+5=x+5 -> (subtract 5 from both sides) 3x=x
(subtract x from both sides) 3x=x -> 3x-x=0
4.Combine like terms
3x-x=0 -> 2x=0
5.Get rid 2 so divide both sides by 2
2x= 0 -> [tex]\frac{2x}{2}[/tex]=[tex]\frac{0}{2}[/tex] ->
x=0

If p, q and r were three statements such that p → q and q → r then p → r, this is called
Answer: Law of syllogism
Step-by-step explanation:
Law of Syllogism is described as
a logical reasoning by using transitivity.a valid argument that applies deductive reasoning to get the final statement. it is similar to transitive property that if a=b and b=c then a=c.So if p, q and r were three statements such that p → q and q → r then p → r, this is called law of syllogism.
For example: When Rita gets internet Shamy gets internet. When Shamy gets internet Raj gets internet.
By law of syllogism : When Rita gets internet Raj gets internet.
7n+5=96 so what is the answer
Answer:
n = 13
Step-by-step explanation:
7n + 5 = 96
Subtract 5 from both sides to get rid of the 5 on the right side:
7n + 5 - 5 = 96 - 5
7n = 91
Divide both sides by 7 to get rid of the coefficient of n:
7n / 7 = 91 / 7
n = 13
Answer: [tex]n=13[/tex]
Subtract 5 from both sides
[tex]7n+5-5=96-5\\7n=91[/tex]
Divide both sides by 7
[tex]7n/7=91/7\\x=13[/tex]
Identify the range of the function. A) (2, 8) B) [2, 8] C) (−5, 9) D) [−5, 9]
Answer:
The answer is "Option A"
Step-by-step explanation:
The domain is the collection of the value, which belongs to the separate variable (horizontal axis). So, to find a region with a graph, it must search for the function, which starts and end. And at all these levels we are searching at x-values.
Its starting point is (2,9) and the ending point is (8,3). Therefore, x= 2 to x=8 is the domain.
it's from Khan Academy and there are answer choices it's called interpet negative number addition and subtraction expression
Answer: Hi!
Answers B and D are correct.
For B, since negative numbers are on the left side of the number line, a positive number would have to be to the right of a negative number. Since we are adding a negative and a positive number of the same absolute value (9), they would cancel out to 0, which makes D true.
Hope this helps!
Hi there! Hopefully this helps!

Answers: D, B.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Explanation for D: -9 + 9 = 0.
Explanation for B: Negative numbers are on the LEFT side of the number line.
And positive numbers are on the right.

A basket of fruit contains 4 bananas, 3 apples, and 5 oranges. You intend to
draw a piece of fruit from the basket, keep it, draw a 2nd piece of fruit from the
basket, keep that, and then draw a third piece of fruit from the same basket. What
is the probability of selecting one banana, then one apple, then one orange, in
that order, from the basket if you are blindfolded?
Hi
draw 1 : 4/12 = 1/3
draw2 : 3/11
draw 3 : 5/10 = 1/2
so probability to have : 1 banana then 1 apple then 1 orange is : 1/3*3/11*1/2 = 3/66 = 3*1 / 2*3*11 = 1/22
Answer:
1/22
Step-by-step explanation:
Work out the probability of selecting each fruit then times them together so
there are 12 fruits in total and 4 bananas so the chance of selecting a banana is 4/12 simplified 1/3
then as you dont put the banana back there is only 11 fruits left in the basket and 3 are apples so the chance of selecting an apple is 3/11
then as you dont put the apple back there is only 10 fruit left in the basket and 5 are oranges so the chance of selecting an orange is 5/10 simplified 1/2
then we multiply them all together 1/3 x 3/11 x 1/2 3/66 to get which simplifies to 1/22

Thirty overweight males agree to participate in a study of the effectiveness of three weight-loss treatments: X, Y, and Z. The researcher calculates the
body fat composition of each subject. The response variable is the reduction in body fat after six weeks of treatment. Previous studies have shown the
effects of a diet may vary based on a subject's initial body fat composition. How should the subjects be blocked? Explain.
They should be blocked alphabetically so the subjects are as different as possible.
They should be blocked by age because weight loss is more difficult to achieve as you get older.
They should be blocked by height because weight loss is easier to achieve for taller people.
They should be blocked by body fat composition so the subjects are as similar as possible.
Blocking should not be used in this experiment.
Answer:
They should be blocked by body fat composition so the subjects are as similar as possible.
Step-by-step explanation:
It's D .
Blocking here means how should the subjects be arranged in terms of body fat or weight.
Option A is wrong because alphabetically controlling body fat would not get desired results.
Option B is wrong because different age groups would yield different results.
Option C is wrong also because weight loss is not dependent on taller people.
Option D is correct because controlling body fat would yield best possible results in ascending or descending order
Option E is incorrect because arranging data in ascending or descending order would simplify the researches experiments.

∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+10)^{\circ}∠A=(7x+10) ∘ and m\angle B=(7x-26)^{\circ}∠B=(7x−26) ∘ , then find the measure of \angle A∠A
Answer:
x = 25
Step-by-step explanation:
The measure of angle A is 108°
What is a angle?An angle is formed when two straight lines or rays meet at a common endpoint.
What is a supplementary angle?Supplementary angles are those angles that sum up to 180 degrees.
Given that angle A and angle B are supplementary angle
∠A=(7x+10)°
∠B=(7x−26)°
(7x+10)° + (7x−26)° =180°
14x - 16° =180°
14x =196°
x= 14°
∠A=(7x+10)°
∠A=(7(14) +10)°
∠A= 108°
Thus the measure of angle A is 108°

What is the change in temperature from 20 degrees to -8 degrees ?
Answer:
28 degrees relatively
Step-by-step explanation:

Answer:
20 degrees Celsius to Fahrenheit
20 degrees Celsius (ºC) are equal to 68 degrees Fahrenheit (ºF):
20ºC = 68ºF
Calculation
The temperature T in degrees Fahrenheit (ºF) is equal to 20 degrees Celsius (ºC) times 9/5 plus 32:

Ben rents a car for one day. The charge is $20 plus the $0.12 per mile. He wants to spend exactly $80. How many miles can he drive? Write and solve an equation to find how many miles Ben can driv
Answer:
Ben can drive 500 miles for $ 80
Step-by-step explanation:
Let y be the cost of traveling and x be the number of miles . The charge is $20 plus the $0.12 per mile which means the cost $ 20 is constant and an additional cost of $ 0.12 is spent on every mile. Then according to the given conditions the equation will be
y = $20 + $ 0.12(x) where x is the number of miles
Now we can solve x for y= 80
$ 80= $20 + 0.12 (x)
$ 60 = 0.12x
x= 60/ 0.12= 500
Ben can drive 500 miles for $ 80
Make x the subject of the formula a(x-b)=a^2+bx
Answer:
x = [tex]\frac{a(a + b)}{a-b}[/tex]
Step-by-step explanation:
Step 1: Write out formula
a(x - b) = a² + bx
Step 2: Distribute
ax - ab = a² + bx
Step 3: Add ab to both sides
ax = a² + bx + ab
Step 4: Subtract bx on both sides
ax - bx = a² + ab
Step 5: Factor
x(a - b) = a² + ab
Step 6: Divide (a - b) on both sides
x = [tex]\frac{a^{2} + ab}{a-b}[/tex]
Step 7: Factor
x = [tex]\frac{a(a + b)}{a-b}[/tex]
And we have our final answer!
