<u><em>Answer:</em></u>

She had more correct answers on the first quiz

<u><em>Explanation:</em></u>

<u>1- For the first quiz:</u>

We know that the quiz had a total of 15 questions and that Kelly had \frac{4}{5} of those correct

<u>This means that:</u>

Number of correct answers = \frac{4}{5}*15 = 12 answers

<u>2- For the second quiz:</u>

We know that the quiz had a total of 12 questions and that Kelly had \frac{5}{6} of those correct

<u>This means that:</u>

Number of correct answers = \frac{5}{6}*12=10 answers

<u>3- Comparing the number of correct answers:</u>

From the above calculations, we know that she had 12 correct answers on the first quiz and 10 on the second

<u>This means that</u> she had more correct answers on the first quiz

Hope this helps :)

Answer:

They will be picked up at 2 \frac{1}{4} yards above sea level

Step-by-step explanation:

Let us consider sea level as reference and positions above sea level as positive and below sea level as negative.

With respect to this reference,

the position of top most point is +17 \frac{3}{4} yards

and the position of lower most point is -13 \frac{1}{4} yards

⇒ The position of midpoint is \frac{+17 \frac{3}{4} - 13 \frac{1}{4}}{2}

                                              = +2 \frac{1}{4}

∴ <u>They will be picked up at 2 \frac{1}{4} yards above sea level</u>

Wrench sets designed for SI bolts often include wrenches at 1 mm increments while wrench sets designed for imperial bolts often
juin [17]
So 5/8 inches to milimeters
we know that 1 in=2.54 cm so
5/8 in times 2.54= 1.5875 cm
1 cm=10 mm
1.5875 cm times 10=15.875mm aprox 16 mm, but best to go smaller since it won't fit if bigger

answer: 16mm (my recomendation would be 15mm)

yan [13]

Answer:

  138.16 in²

Step-by-step explanation:

The surface area SA of the cone is the sum of the base area B and the lateral area LA. The lateral area is half the product of the circumference and the slant height. The radius is half the diameter, so is 4 inches.

  SA = B + LA

  = πr² + (1/2)(2πrh) . . . . where h is the slant height

  = (πr)(r +h)

Filling in the numbers, you have ...

  SA = (3.14)(4 in)(4 in + 7 in) = 3.14×(44 in²) = 138.16 in²

The sum of the ages of Rudy and his father is 58 years. The difference in their ages is 32 years. How old is each ?
Anestetic [448]

Answer:

Rudy is 13 years old. Her father is 45 years old.

Step-by-step explanation:

It's very simple actually!

<u>All you need to do is subtract 32:</u>

58 - 32 = 26

<u>Then divide:</u>

<u />

26 ÷ 2 = 13

13 is Rudy's age. Let's find her father's age!

<u>We then add 32 back to 13:</u>

32 + 13 = 45

And there you have it!

Hope this helped!  :)
