Will thank rate five stars and give brainlist anser to first person to answer!
Answers
Answer:
A. a = 16.23 and b = 17.99
Step-by-step explanation:
The addition of the three angles of the triangle is equal to 180°. So,
C + 64° + 85° = 180°
C = 180° - 64° - 85°
C = 31°
The law of sine states:
sin(A)/a = sin(B)/b = sin(C)/c
where c is the side opposite to angle C
Taking angles A and C, and sides a and c, we get
sin(A)/a = sin(C)/c
sin(64°)/a = sin(31°)/9.3
sin(64°)*9.3/sin(31°) = a
a = 16.23
Taking angles B and C, and sides b and c, we get
sin(B)/b = sin(C)/c
sin(85°)/b = sin(31°)/9.3
sin(85°)*9.3/sin(31°) = b
b = 17.99

What is the length of segment RS
Answers
To find this, you can make a right triangle by connecting points R and S at a common point to form a right angle. The segments made would be 5 units and 12 units long. Using the Pythagorean Theorem, the segment RS must be 13 units.
Answer: 13 units
Step-by-step explanation:
The length of line segment AB with points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)[/tex] is given by distance formula as :
[tex]\text{AB}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Now, the length of line segment RS with points [tex]R(-4,-3)\ and\ S(1,9)[/tex] is given by distance formula as :
[tex]\text{RS}=\sqrt{(1-(-4))^2+(9-(-3))^2}\\\Rightarrow\ RS=\sqrt{(5)^2+(12)^2}\\\Rightarrow\ RS=\sqrt{25+144}=\sqrt{169}\\\Rightarrow\ RS=13[/tex]
Hence, the length of segment RS= 13 units

Triangle with height of 16 inches and base of 14 inches.
Answers
- We know this because...
1. The calculations of a triangle is... 1/2 x b(h)
2. So first, lets calculate the b(h) first, which is 16 x 14 = 224 square inches.
- This isn't the correct answer because it is the area of a rectangle.
3. Second, lets calculate 1/2 x 224 = 112 square inches.
- We did this calculation because we are talking about a triangle.
- So, the total square inches of the club sticker is 112 square inches.
Hope this helps! :)

The correct answer is 112 Square Inches.

Highlighter pens cost $3.86 per set at an office supply store. Which equation can be used to determine the price, P, of n sets of these pens? n = 3.86P P equals 3.86 over n n equals 3.86 over P P = 3.86n
Answers
Meaning N as the number of sets and P as the total price of the # of sets times the unit price.
P=Price
N=Number of pens you buy
The price depends on the number of pens that you buy. Each pen costs $3.86, so you will have to multiply the price of each pen by the number of pens that you buy and it will give you your price to pay.

Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?
y = 2x – 2
y = 2x + 2
y = x + 2
y = x – 2
Answers
slope = (6 - 2) / (4 - 0) = 4/4 = 1
y = mx + b
slope(m) = 1
use either of ur points (0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 1(0) + b
2 = b
ur equation is : y = x + 2 <==
Answer:
The correct option is 3.
Step-by-step explanation:
If a line passing through two points then the equation of line is
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
It is given that CD passes through points (0, 2) and (4, 6), so the equation of line is
[tex]y-2=\frac{6-2}{4-0}(x-0)[/tex]
[tex]y-2=\frac{4}{4}(x)[/tex]
[tex]y-2=x[/tex]
Add 2 on both the sides.
[tex]y=x+2[/tex]
The equation of line CD is y=x+2. Therefore the correct option is 3.

Answers
We can solve this problem by stating that the summation of momentums must be zero. That is, the momentum at one end of the pivot must be equal to the momentum at the other end.
Momentum 1 = Momentum 2
Since Momentum is the product of Force and Distance, and with this rule created, we can say that:
F1 * d1 = F2 * d2
Where,
F1 = 60 lbs
d1 = 2 inches from the pivot
F2 = unknown X
d2 = 3 inches from the pivot
Substituting to the equation to find for F2:
60 lbs * 2 inches = F2 * 3 inches
F2 = 40 lbs
Therefore 40 lbs of upward force must be pushed to open the valve.
Answer: B
Final Answer:
40 lbs of upward force must be pushed to open the valve that is option B is correct.

If a person weighs 240 pounds on Earth, what would be the difference in weight of the same person on Mars and on the Moon
Answers
Answer:
Mars: [tex]\Delta W = 144\,lbf[/tex], Moon: [tex]\Delta W = 199.2\,lbf[/tex]
Step-by-step explanation:
The gravitational acceleration experimented by the same person on the Moon is equivalent to a sixth of the indicator on Earth and the same indicator on Mars is about 40 % of the terrestrial acceleration. Then, the difference in weight are computed below:
Mars:
[tex]\Delta W = (1 - 0.4) \cdot (240\,lbf)[/tex]
[tex]\Delta W = 144\,lbf[/tex]
Moon:
[tex]\Delta W = (1 - 0.17) \cdot (240\,lbf)[/tex]

A rectangle has a perimeter of 84 meters and a length of 35 meters. What is the width of the rectangle?
Answers
Where L is the length and W is the width.
We know the perimeter and we know the length and we want to find the width.
Substitute the values back into the formula.
2(35) + 2W = 84
70 + 2W = 84
2W = 14 <-- Subtract both sides by 70
W = 7 <-- Divide both sides by 2
So, width is 7 meters long.
84 - 70
14 / 2
The width of the rectangle is 7.
