The length of TR is 17 units. What are the lengths of SV and QT? (please hurry i dont get this question) also i need each individual answer, not SV + QT, I need SV and QT
Answer:
QT = 21SV = 41Step-by-step explanation:
From the diagram, it can be seen that TR is parallel to RV. This means that TR = RV. Given TR = 17 and RV = 3x+2
3x+2 = 17
3x = 17-2
3x = 15
x = 5
RV = 3(5)+2 = 17
QV = 4x+1 = 4(5)+1
QV = 21
Using Pythagoras theorem on ΔQRV to get RQ
QV² = QR²+RV²
21² = QR²+17²
QR² = 21²-17²
QR = 12.33
Using Pythagoras theorem on ΔQRT to get QT
From ΔQRT,
QT² = QR²+TR²
QT² = 12.33²+17²
QR² = 152.0289+289
QT² = 441.0289
QT =21
Since TS = 9(5)-4 = 41
Using Pythagoras theorem on ΔTRS
From ΔTRS,
TS² = RS²+TR²
41² = RS²+17²
RS² = 41²-17²
RS² = 1392
RS = 37.31
Similarly Using Pythagoras theorem on ΔRSV
From ΔRSV,
SV² = RV²+RS²
SV² = 17²+37.31²
SV² = 1681.0361
SV = 41
Answer:
SV=41
QT=21

Hi!
The negative signs cancel out iin the equation to make a positive 7.
The 4 is already positive.
So that makes it 4 + 7!

Sonia is hanging up decorations in the ratio of 3red: 2green: 4white . If she hangs up 135 decorations in total , how many of each colour does she hang up
Answer:
She hung 45reds, 30greens and 60whites
Step-by-step explanation:
If Sonia is hanging up decorations in the ratio of 3red: 2green: 4white, the total amount of different she hung is 3+2+4 = 9different colours.
Of she hung 135decorations in total, the number of red = 3/9 × 135 = 45reds
Number of green = 2/9 × 135 = 30greens
Numbe of white = 4/9 × 135= 60whites
She hung 45reds, 30greens and 60whites

Teo has a combination of quarters, loonies, and toonies in his pocket.
He knows he has 9 coins in total and that he has at least one of each
type of coin.
a) hwo many outcomes end with over 8$
b) How many different combinations of coins could Teo use to pay for an item
that costs between $10 and $12, if he uses fewer toonies than loonies?
Answer:
343
Step-by-step explanation:
There are quarters(25¢), loonies ($1), and toonies ($2)
And total number of coins is 9
If loonies ($1), and toonies ($2) are one, then quarters(25¢) is 7
If quarters(25¢), and toonies ($2) are one, then loonies ($1)is 7
If loonies ($1), and quarters(25¢) are one, then toonies ($2) is 7
So possible number number of combination for an item that cost between $10 and $12 is
= 1^3 * 1^3 * 7^3
= 343
hope this helps, stay safe :)
The number of different combinations of coins could Teo use to pay for an item that costs between $10 and $12 is 17.
What are Combinations?Combinations are defined as the arrangement of objects or numbers in a way such that the order of the arrangement does not matter.
Given that,
Teo has a combination of quarters, loonies, and toonies in his pocket.
Total number of coins = 9
1 quarter = $0.75
1 loonie = $1
1 toonie = $2
If he uses fewer toonies than loonies,
Total number of combinations of 9 coins = 1³ × 1³ × 7³ = 343
We need the number of combinations in between $10 and $12.
We can form the following combinations.
(2 × $1) + $2 gives $4. Remaining can be 8, 9 and 10 quarter coins.
(3 × $1) + (2 × $2) gives $7. Remaining can be 4, 5 and 6 quarter coins.
(3 × $1) + (1 × $2) gives $5. Remaining can be 7, 8 and 9 quarter coins.
(4 × $1) + (3 × $2) gives $10. Remaining can be 1 or 2 quarter coins.
(4 × $1) + (2 × $2) gives $8. Remaining can be 3, 4 and 5 quarter coins.
(4 × $1) + (1 × $2) gives $6. Remaining can be 6, 7 and 8 quarter coins.
Total number of combinations = 3 + 3 + 3 + 2 + 3 + 3 = 17
Hence the total number of combinations are 17.

solve for t
Answer:
t can equal 7 or -7
Step-by-step explanation:
Answer:
t=7 or t=-7
Step-by-step explanation:
To solve for t, we need to get t alone. To do this, perform the opposite of what is being done to the equation. Keep in mind, everything must be performed to both sides.
t^2=49
t is being squared. The opposite of squared is the square root. Take the square root of both sides.
√t^2=√49
t=√49
t=±7
So, t is equal to 7 or -7

Step-by-step explanation:
You are playing a board game with a friend. She owns and has developed the tiles Green Gardens and Silver Sidewalks. If you roll an 8, you will land on Green Gardens and owe her $1500. You will be able to pay, but you will not have money left afterward. If you roll a 9, you will land on the tile King's Taxes and have to pay $75. If you roll a 10, you will land on Silver Sidewalks and owe her $2000, which is more than you can pay—and lose the game. If you roll a 7 or less, you will not have to pay any money to anyone. Your friend offers you insurance. Pay her $500 before you roll and even if you land on Green Gardens or Silver Sidewalks, you will not have to pay any additional money. However, if you roll a 7, you will have to pay her $1000. Use probabilities to find expected values. Then compare the amount of money you should expect to pay out on average, under her insurance and by chance. Is her deal fair?
Answer:
The expected value can be calculated as:
Es = x₁*p₁ + x₂*p2 + .....
where xₙ is the event (the amount of money that you win or lose, and pₙ is the probability for the event)
for example, in a 10 side dice, the probability of obtaining a specific number is 1/10.
we have a d10 i guess (a dice with 10 sides, 1 to 10)
if you roll from 1 to 7, nothing happens.
If you roll an 8, you lose $1500
if you roll a 9, you lose $75
if you roll a 10, you lose $2000 (and the game)
the expected value is,
Es = 1/10*(7*0 - 1*$1500 - 1*$75 - 1*$2000) = -$357
in the second case, you start paying $500.
if you roll a 7, you must pay $1000, if else, nothing happens.
Then the expected value is
Es = -$500 - 1/10*(-1*$1000 + 9*$0) = -$600
So the expected value is smaller in this case, so the deal is not fair

Answer:
<CAB and <DAE are vertical angles
<EAB and <CAD are vertical angles
Step-by-step explanation:
this is because they are formed by the prolongation of the sides of the other angles and are opposite to them on the other side of the vertex.
Options B and D are correct. The vertical angles are ∠CAD and ∠BAE AND ∠EAB and ∠CAD.
Vertical angles are angles that are opposite to each other in line geometry. The size of the angles must be the same.
According to the diagram shown, we can see that ∠CAD and ∠BAE are opposite to each other with similar measures.
This means that both angles are vertically opposite. he same is applicable to ∠EAB and ∠CAD.Hence the vertical angles are ∠CAD and ∠BAE AND ∠EAB and ∠CAD.
