Anettt [7]1 year ago

Ada is <u>incorrect</u>, as the length of diagonal SQ is not two times the length of diagonal OM. The theorem used is the Pythagoras Theorem.

For Rectangle PQRS:-

By Pythagoras Theorem, in right triangle PQS,

SQ² = PQ² + PS²,

or, SQ² = 8² + 16² sq. inches,

or, SQ² = 64 + 256 sq. inches,

or, SQ = √320 sq. inches,

or, SQ = 8√5 inches.

Thus, the length of diagonal SQ, of rectangle PQRS is 8√5 inches.

For Square LMNO:-

By Pythagoras Theorem, in right triangle LMO,

OM² = LM² + LO²,

or, OM² = 8² + 8² sq. inches,

or, OM² = 64 + 64 sq. inches,

or, OM = √128 sq. inches,

or, OM = 8√2 inches.

Thus, the length of diagonal OM, of square LMNO is 8√2 inches.

We know that 2*OM ≠ SQ, as 2*8√2 ≈ 8√5.

Thus, Ada is <u>incorrect</u>, as the length of diagonal SQ is not two times the length of diagonal OM. The theorem used is the Pythagoras Theorem.

1. Jackie is saving money to buy a new cell phone. The cell phone costs $175, but she has
Serggg [28]

Answer:

32%

Step-by-step explanation:

<h3>Given that:</h3>
  • Jackie is saving money to buy a new cell phone.
  • The cell phone costs $175
  • she has already saved $56
<h3>To find:</h3>
  • The percent of the cost of the cell phone has Jackie saved

In order to find the percent of the cost of the cell phone has Jackie saved,

  1. divide the cost of the cell phone by the amount of the money Jackie saved
  2. Multiply the result (1) by 100

See below how it's done:

\dfrac{56}{175}  \times 100

dividing yields:

0.32 \times 100

multiplying yields:

32\%

Alternative:

Instead of dividing,we can consider reducing the fraction and multiply that with 100 to get the answer.

\dfrac{56}{175}  \times 100 \\  \implies  \frac{8}{25}  \times 100 \\ \implies 8 \times 4 \\  \implies \boxed{32\%}

In conclusion:

Jackie has saved 32% of the cost of the cell phone

Consider two persons. The age of one persoon isestimated between 25 and 35. The age of the other person isestimated between 15 a
Andrei [34K]

Answer:

Q1. The estimated sum of the two people are between 40 and 55 years old.

Q2. The first person is between 10 and 15 years older.

Step-by-step explanation:

We are given Age Range's for 2 people. The first question is asking for the sum of the two people's ages. In this case we can just <u><em>add</em></u> the two minimum ages together and then the two maximum ages like so,

<u>min:</u> 25 + 15 = 40

<u>max:</u> 35 + 20 = 55

So the estimated sum of the two people are between 40 and 55 years old.

The second question asks how much older the First person is from the Second person. We can calculate this by <u><em>subtracting</em></u> both age ranges like so,

<u>min:</u> 25 - 15 = 10

<u>max:</u> 35 - 20 = 15

So the first person is between 10 and 15 years older.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
