Answer:

Hello There the answer is Δ QUT ≅ Δ SVR. (Proved)

Step-by-step explanation:

See the given diagram below.

Given that QV = SU

⇒ - QV = - SU

⇒ QS - QV = QS - SU

⇒ SV = QU .......... (1)

Now, also given that QT = SR

Then between Δ QUT and Δ SVR,  

(i) QT = SR {Given}

(ii) QU = SV {Already prooveed}

and  (iii) ∠ QUT = ∠ SVR {They are 90°}

Therefore, by Side-Side-Angle i.e. SSA criteria it is proved that Δ QUT ≅ Δ SVR. (Proved)

Hope it helps!

Estimate the sum 8/10 + 1/9
RideAnS [48]

Answer:

41/45

Step by Step Explanation:

Add: 8/

10

+ 1/

9

= 8 · 9/

10 · 9

+ 1 · 10/

9 · 10

= 72/

90

+ 10/

90

= 72 + 10/

90

= 82/

90

= 2 · 41/

2 · 45

= 41/

45

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 9) = 90. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 9 = 90. In the following intermediate step, cancel by a common factor of 2 gives 41/

45

.

In other words - eight tenths plus one ninth = forty-one forty-fifths.

Hey there :)

( 5y + 9 )( 6y - 1 )

We need to use FOIL to expand, that is
First Terms
Outer Terms
Inner Terms
Last Terms

     First          Outer         Inner      Last
( 5y )( 6y ) + ( 5y )( - 1 ) + 9 ( 6y ) + 9 ( - 1 )
    30y²     -        5y      +    54y   -       9

Combine, if any, the like-terms
30y² + 49y - 9
