29 to 33 pls it worth 10 points pls do it

PLEASE ANSWER ASAP the quiz is almost over and I need to turn this in

andriy [413]

Answer:

X = 10

Step-by-step explanation:

the triangles are similar meaning one is smaller we have all the sides on the smaller one

10 to 25 is a 2.5 increase

so 4 x 2.5 = 10

Two high-speed ferries leave at the same time from a city to go to the same island. The first ferry, the Cat, travels at 34 m

djyliett [7]

Answer:

They will be 5 miles apart in 1 hour

Step-by-step explanation:

Here, we want to calculate the time it will take for the two ferries to be 5 miles apart

Mathematically; distance = speed * time

Let the number of hours be x

In x hours, the cat will have traveled 34 * x = 34x miles

In x hours, the Bird will have traveled 29 * x = 29x miles

So;

34x - 29x = 5

5x = 5

x = 5/5

x = 1 hour

RSTU is a parallelogram. If m∠SRV = 48° and m∠SVR = 54°, explain how you can find the measure of ∠TUV. Show all steps of your wo

const2013 [10]

Opposite angles in a parallelogram have equal measure.

The measure of angle TUV is 78 degrees

The given parameters are:

$\mathbf{\angle SRV = 48}$

$\mathbf{\angle SVR = 54}$

Start by calculating angle RSV.

$\mathbf{\angle RSV + \angle SVR + \angle SRV = 180}$ --- angles in a triangle

So, we have:

$\mathbf{\angle RSV + 54 + 48= 180}$

$\mathbf{\angle RSV + 102= 180}$

Subtract 102 from both sides

$\mathbf{\angle RSV = 78}$

Angles RSV and TUV are corresponding angles.

So, we have:

$\mathbf{\angle TUV = \angle RSV = 78}$

Rewrite as:

$\mathbf{\angle TUV = 78}$

Hence, the measure of angle TUV is 78 degrees

How to get the answers?

By inclusion/exclusion,

$n(P' \cup Q) = n(P') + n(Q) - n(P' \cap Q)$

We have

$n(\xi) = n(P) + n(P') \implies n(P') = 28 - n(P)$

so that

$n(P' \cup Q) = (28 - n(P)) + n(Q) - 2n(P) = 28 - 3n(P) + n(Q)$

Now,

$n(\xi) = 28 \implies n(P \cup Q) = 28 - 7 = 21$

and by inclusion/exclusion,

$n(P \cup Q) = n(P) + n(Q) - n(P \cap Q)$

Decompose $Q$ into the union of two disjoint sets:

$Q = (P \cap Q) \cup (P' \cap Q)$

Since they're disjoint,

$n(Q) = n(P\cap Q) + n(P'\cap Q) \implies n(Q) = n(P\cap Q) + 2n(P)$

$\implies n(P \cup Q) = n(P) + (n(P\cap Q) + 2n(P)) - n(P \cap Q)$

$\implies 21 = 3n(P)$

$\implies n(P) = 7$

From the Venn diagram, we see there are 3 elements unique to $P$ - by the way, this is the set $P \cap Q'$ - so $n(P\cap Q) = 7-3 = 4$ , and it follows that

$n(Q) = n(P\cap Q) + 2n(P) = 4 + 2\times7 = 18$

Finally, we get for (a)

$n(P' \cup Q) = 28 - 3n(P) + n(Q) = 28 - 3\times7 + 18 = \boxed{25}$

For (b), we have by inclusion/exclusion that

$n(P \cup Q') = n(P) + n(Q) - n(P \cap Q') = 7 + 18 - 3 = \boxed{22}$

PLEASE HELP MEEEEEEEEEE

Alona [7]

Answer:

15

Step-by-step explanation:

here's your solution

=> Both the traingle are similar hence ,

=> it's corresponding sides are in equal ratio

=> so,8/20 = 6/y

=> 8y = 20*6

=> y= 20*6/8

=> y = 15

 hope it helps
