An equilateral triangle LMQ is drawn
Bogdan [553]

The measure of the ∠LQP is 120°

Step-by-step explanation:

The diagram of the question is as attached in the image.

LMNP is a square. We know that for a square all sides are equal and intersects at 90°

Hence, LM=MP=PN=LN

and ∠LMP= ∠MPN= ∠PNL= ∠NLM= 90°

Δ LMQ is an equilateral triangle

We know that for equilateral triangle all sides are equal and all angles are 60°

LM=LQ=QM=MP=PN=LN and

∠LQM= ∠QML= ∠MLQ= 60°

∠LQP= ∠LQM+ ∠MQP   eq 1

In Δ MPQ

∠QPM=90° and ∠PMQ= 90°-60°=30°

Hence, ∠MQP= 180°-(90°+30°)=60°

Putting the value of ∠MQP and ∠LQM in equation 1

∠LQP= 60°+60°= 120°

Thus the measure of ∠LQP=120°

3. Victoria counts this week's food donations at a pet shelter. There are 16 full cases of canned food. There are 4 cases of can
xxMikexx [17]

Answer:

We know that C is the total number of cans in a complete case.

Victoria counts:

16 full cases, so in those we have: 16*C cans.

4 cases with 5 missing cans, so in those we have:

Then if each case has C cans, the cases that are missing 5 cans have:

C - 5 cans.

Then in those four cases we have a total of: 4*(C - 5) cans.

And Victoria knows that there are 220 cans, then we have that:

16*C + 4*(C - 5) = 220

16*C + 4*C - 20 = 220

16*C + 4*C = 220 + 20 = 240

20*C = 240

C = 240/20 = 12

Then each case has 12 cans.

Then the number of cans in the cases with missing cans is:

12 cans - 5 cans = 7 cans.

Ania kupiła w księgarni dwie książki i zapłaciła 37,20, a jurek za swoje zapłacił trzy razy więcej. Ile zapłacił jurek
SVETLANKA909090 [29]

Answer:

111.60

Question:

Ania bought two books in a bookstore and paid 37.20, and Jurek paid three times more for his. How much did Jurek pay?

Step-by-step explanation:

This is a question on multiplying decimals by natural numbers.

Number if books bought by Ania = 2

Cost for the two books = 37.20

Jurek paid = 3 times the amount Ania paid

Amount Jurek paid = 3×37.20

To multiply decimals with whole numbers, first multiply without the decimals

3×3720 = 11160

3 has no decimal place

37.20 has 2 decimal place

Therefore the answer would be in two decimal place = 111.60

So 3× 37.2= 111.60
