Answer:
Step-by-step explanation:
x=(115cos50+160cos130)=-28.9254
y=(115sin50+160sin130)=210.6622
m^2=x^2+y^2
m=212.64
angle=180+arctan(y/x)
angle=97.82
v=212.64 at 97.82 degrees
Terra wants wall-to-wall carpeting in her bedroom, which measures 10’ x 12’6”. Carpeting is on sale for $24.99 per sq. yd. What is the cost? (Remember to round your dimensions before calculating the area)
Answer:
$347.08
Step-by-step explanation:
10' x 12'6" = 125 ft^2
one yd^2 = 9 ft^2
125/9 = 13.89 yd^2
13.89 x $24.99 = $347.08

Answer:
5) First you have to find x, then use it with supplementary angles theorem.
6) STQ = 150˚
Step-by-step explanation:
To find x, add (2x+8), (71-x), and 90˚ together to add up to 180˚ (those three angles are supplementary):
(2x+8) + (71-x) + 90 = 180˚
x + 169 = 180
Then solve for x:
x = 11
You can check if x is right by inputing it back into the two equations and see if all three of the angle measures together equal 180˚.
Now, you only need m∠MTS (2x+8) to find m∠STQ...
m∠MTS + m∠STQ = 180˚ because they are supplementary angles.
Input the found x to find m∠MTS:
(2(11)+8) = 30
Subtract 30 from 180 to find m∠STQ:
180 - 30 = 150
m∠STQ = 150˚
Hope this helped :)
find the length of the third side of the right triangle!!!!
Answer:
8
Step-by-step explanation:
There are two ways to solve this!
1. Use the Pythagorean Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 10^2
100 - 36 = b^2
64 = b^2
8 = b
2. Shortcut using 3-4-5 triangles
A 3-4-5 triangle has to do with the ratios of each side.
In this case, it's 6-8-10, as each number is multiplied by two with the same 3-4-5 ratio. This is a good shortcut for these types of problems and will be handy on tests like the SAT as well! :)

Which postulate proves these two
triangles are congruent?
A. ASA
B. SAS
C. None, not congruent
D. HL
Answer:
it may be B but I think it's C
Step-by-step explanation:
not sure if this is right, but I would say not congruent. it may be sas but in order for it to be sas then the Angle must be in-between the two congruent sides
Both triangles are congruent by (SAS) side-angle-side postulate.
The correct option is B.
What are congruent triangles?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure. These triangles can be slides, rotated, flipped and turned to be looked identical.
Given,
Two triangles
ABC and DEC
AB = DE (Given)
BC = EC (Given)
∠ACB = ∠DCE (Vertical angles at intersection of DB and AE)
By, Side-Angle-side theorem of congruent triangles,
ΔABC ≅ΔDEC
Hence, by side-angle-side (SAS) postulate, both triangles are congruent.

Carrah has these cans of soup in her kitchen:
2 cans of tomato soup
3 cans of chicken soup
2 cans of cheese soup
2 cans of potato soup
1 can of beef soup
Carrah will randomly choose one can of soup. Then she will put it back and randomly choose another can of soup. What is the probability
that she will choose a can of tomato soup and then a can of cheese soup?
2/10 (or 1/5 ) Times 2/10 (or 1/5).
This will equal a 1 out of 25 chance.
You take the number of items you are looking for ( for example, 2 Tomato Cans) Divided by the total items you have (All 10 cans that are a possibility). Then you take your probabilities, and multiply them.

Fernando had to pay $1.40 in sales tax when he purchased a shirt . If the sales tax rate is 7% how much did his shirt cost
Answer:
$20
Step-by-step explanation:
Work backwards so Price(.07) = $1.40 so x (.07) = 1.40, solving for x then
x = 1.4/.07 so x = 20
The cost of the shirt of Fernando is $20.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Fernando had to pay $1.40 in sales tax when he purchased a shirt . The sales tax rate is 7%.
The cost of the shirt is calculated as,
$1.40 = x (.07)
x = 1.4/.07
x = $20
Therefore, the cost of the shirt of Fernando is $20.

So for part (i) 3 multiply p added to 4 times r = 3p + 4r
For part (ii) since subtraction can seem like a negative number you stipulate that 3q is greater than 2p so that is will hold true!
(iii) I'm not sure what the [3] means but just using the numbers [tex]\frac{2}{3}[/tex]x, since of means multiply and add 2y then you have 2y + [tex]\frac{2}{3}[/tex] x

The letters P-R-O-B-A-B-I-L-I-T-Y are written on a set of cards. You mix the cards thoroughly. Without looking, you draw one letter then you draw another without replacing the first. Find the probability that you will select a P followed by a Y.
P(P, then Y) =
Answer:
P(P, then Y)=(1/11)(1/10)=1/110
Step-by-step explanation:
The number of letters in probability is 11.
There is 1 P.
The probability of drawing a P on draw 1 is the number of ways of drawing a P, which is 1, divided by the number of ways of drawing any letter, which is 11. Thus:
Probability of drawing a P on the first draw is 1/11.
There are now 10 letters left. There is 1 Y. so
Probability of drawing a Y on the second draw given that you drew a P on the first draw is 1/10.
The probability of drawing a P on the first draw and a Y on the second draw is
(probability of a P on draw 1)(probability of drawing a Y on draw 2, given a P on draw 1)
P(P, then Y)=(1/11)(1/10)=1/110

Solve : -3a+4 = 0
Subtract 4 from both sides of the equation :
-3a = -4
Multiply both sides of the equation by (-1) : 3a = 4
Divide both sides of the equation by 3:
a = 4/3 = 1.333
