What is the measure of ∠R?
Answer:
∠ R ≈ 36.9°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos R = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RT}{RS}[/tex] = [tex]\frac{8}{10}[/tex] , thus
∠ R = [tex]cos^{-1}[/tex] ([tex]\frac{8}{10}[/tex] ) ≈ 36.9° ( to 1 dec. place )

question 1: which of these points lies on the line y = -x + 2
question 2: evaluate: -ab-a if a=-4 and b =-5
Answer:
1. b
2. -16
Step-by-step explanation:
1. -1+2 is equal to 1 so it works
You plug in each of the coordinates x and y variables on the graph and find one that satisfies the equation.
2. -(-4)(-5) is -20
-(-4) is = 4
-20+4 is -16
All else being equal, a study with which of the following error ranges would be
the most reliable?
A. +-6 percentage points
B. +-15 percentage points
C. +-9 percentage points
D.+- 112 percentage points
The study with an error range of +-6 percentage points would be the most reliable.
As larger error ranges, such as options B, C, and D, indicate a greater degree of uncertainty and variability in the dat This reduces the reliability and precision of the study's findings.
So, when all other factors are equal, a study with a smaller error range, like with +-6 percentage points, would be considered more reliable.
Thus, with an error range of +-6 percentage points, has the smallest range.

In the diagram below, the measure of angle 3 is 140, what is the measure of angle 5 ?
I need help with question number 2.
Help me please !
Answer:
2
Step-by-step explanation:
Angles 3 and 5 are alternate interior angles because they are inside the lines and are on opposite sides of the transversal.
This means they are equal to one another, so 2 is correct because they are alternate interior and angle 5 will be 140 degrees.

Kelly bought a computer that was 20% off the regular price of $1,060. If a 7% sales tax was added to the cost of the computer, what was the total price Kelly paid for it?
Answer: $ 1361.04
Step-by-step explanation:
Discount will be 1060 * 20% = 212
Sales price 1060 + 212 = 1272
Tax 7% = 89.04
Kelly paid 1272 + 89.04 = 1361.04

Find the sum of each infinite geometric series, if it exists
The first series diverges because each successive term is getting multiplied by -3, so the common ratio is larger than 1 in magnitude.
Assuming the second series is
3 - 3/2 + 3/4 - 3/8 + ...
then it converges because the common ratio between terms is -1/2, which is less than 1 in magnitude.
To find the value of the sum, let S denote the n-th partial sum, i.e. the sum of the first n terms in the series:
S = 3 - 3/2 + 3/4 - 3/8 + ... + 3(-1/2)^(n - 2) + 3(-1/2)^(n - 1)
Multiply both sides by -1/2:
(-1/2) S = -3/2 + 3/4 - 3/8 + 3/16 - ... + 3(-1/2)^(n - 1) + 3(-1/2)^n
When we subtract S and (-1/2) S, we see all the middle terms canceling, and we can solve for S:
S - (-1/2) S = 3 - 3(-1/2)^n
S/2 = 3[1 - (-1/2)^n]
S = 6[1 - (-1/2)^n]
As n gets larger, the (-1/2)^n term will converge to 0, leaving us with
lim (n -> infinity) S = 6
so that the series converges to 6.

En la tienda tienen estas ofertas : 1/4 kg de chorizo : 9,25 €. 1/2 kg de queso : 8,50€.¿Cuánto vale 1 kg de cada producto?¿Cuánto cuesta un queso de 2kg?
Answer: 1. €37 and €17
2. €34
Step-by-step explanation:
Given Data:
Cost of 1/4kg of chorizo = €9.25
Cost of 1/2kg of cheese = €8.50
Therefore:
1. Cost of 1kg of each product.
If 1/4 kg or chorizo cost €9.25,
1kg = 1/4 which is known as one fourth or one quarter. There are 4 one fourth in 1
1kg = 1/4 + 1/4 + 1/4 + 1/4
Or
1kg = 4 * €9.25
1kg = €37
Cost of 1kg of chorizo is €37
Cost of 1kg of cheese
If 1/2kg = €8.50
Then; 1kg = 1/2 + 1/2
1kg = €8.50 + €8.50
1kg = €17
Cost of 1kg of cheese = €17
2. Cost of 2kg of cheese.
If 1kg of cheese cost €17
2kg = 2 * €17
2kg = €34
Cost of 2kg of cheese is €34
At most, Alana can spend $40 on carnival tickets. Ride tickets cost $4 each, and food tickets cost $2 each. Alana buys at least 16 tickets. The system of inequalities represents the number of ride tickets, r, and the number of food tickets, f, she buys.
r + f ≥ 16
4r + 2f ≤ 40What is the maximum number of ride tickets she can buy?
Answer:
The maximum number of ride tickets is 4
Step-by-step explanation:
r = number of ride tickets
f = number of food tickets
r + f ≥ 16
4r + 2f ≤ 40
Using these as equations
f = 16 -r
Using this in the second equation
4r+ 2 (16 -r) = 40
4r +32 -2r = 40
2r +32 = 40
2r = 8
r = 4
The maximum number of ride tickets is 4

a) 4

h2 + 24h + 19 = 0
Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.
Answer:
-23.18, -0.82
Step-by-step explanation:
h² + 24h + 19 = 0h²+2h*12+12²-125=0(h+12)²-√125²=0(h+12+11.18)(h+12-11.18)=0(h+23.18)(h+0.82)=0h+23.18=0 ⇒ h= -23.18h+0.82=0 ⇒ h= -0.82Answer:
-23.18, -.82
Step-by-step explanation:
h^2 + 24h + 19 = 0
Subtract 19 from each side
h^2 +24h = -19
Take the coefficient of h
24
Divide by 2
24/2 =12
Square it
12^2 =144
Add this to both sides
h^2 +24h+144 = -19+144
(h+12)^2 =125
Take the square root of each side
sqrt((h+12)^2) =±sqrt(125)
h+12 = ±sqrt(125)
Subtract 12 from each side
h+12-12 = -12 ±sqrt(125)
h =-12 ±sqrt(125)
h = -12 - sqrt(125) = -23.18033989
h = -12 + sqrt(125) = -.819660113
To the nearest hundredth
-23.18, -.82
In 20 words or fewer, describe the kind of relationship you see between the x-coordinates of the midpoint and the endpoint not at the origin
Answer:
Remember, if we have two points (x1, y1) and (x2, y2) we can draw a segment that connects those two points, and we can define the midpoint of those two endpoints as:
( (x1 + x2)/2. ((y1 + y2)/2)
if we are only in the x-axis, then y = 0.
in this situation one of the endpoints seems to be at the origin, and the other is a given value (X´. 0)
Then, the midpoint is:
( (Xp + 0)/2, 0) = (X´/2, 0)
Then, the relationship is:
"the value at the midpoint is half ot the value at the endpoint that is not at the origin"

1. Find the simple interest you will obtain if you deposit $600 in bank for 9 months at 4 %per annum.
2. A man walks at a rate of 1.25 / . Find the time he takes to walk 3.75 km.
Answer:
(1) The formula to calculate simple interest (SI), with principal = 600$, annual rate = 4% = 0.04, and time = 9 months is:
SI = principal x rate x time
= 600 x (0.04/12) x 9
= 18$
(2) The formula to calculate the time that man walked 3.75 km, with rate of 1.25:
Time = Distance/Rate

This word particularly refers to the "artificial codes or ciphers" that humans use to communicate.
The thing in the sentence is more general than language, this refers to communication:
"Communication is a complex system that includes the ways we express ourselves, such as speaking or writing, and ways we receive information, such as listening and reading."
So the actual sentence is false.
