Answer:

31

Step-by-step explanation:

Given :

Alice’s score is twice the difference of Aaron’s score and 5.

The sum of their scores is 320.

To Find :

Each students bowling score.

Solution :

Let , score of Aaron is x .

So , score of Alice is 2(x-5) .

Also , Their sum of scores is equal to 320 .

[tex]x+2(x-5)=320\\\\3x-10=320\\\\x=11[/tex]

Therefore , score of Aaron and Alice 11 and 12 .

Hence , this is the required solution .

Answer:

5, 8, 13, 20, 29

Step-by-step explanation:

[tex]a_n = n^2 +4\\

Plug \: n = 1, \:2, \:3,\: 4, \:5\\

a_1 = 1^2 +4=1+4 =5\\

a_2 = 2^2 +4=4+4 =8\\

a_3= 3^2 +4=9+4 =13\\

a_4= 4^2 +4=16+4 =20\\

a_5= 5^2 +4=25+4 =29\\[/tex]

Answer:

1.4959787 × 10^8

Step-by-step explanation:

Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10^b.

Follow the steps below to see how 149,597,870 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 149,597,870

New Number: 1.49597870

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 4 9 5 9 7 8 7 0

Decimal Count: 1 2 3 4 5 6 7 8

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10^b

a = 1.4959787 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

1.4959787 x 10^8

Step 4

Check your work:

10^8 = 100,000,000 x 1.4959787 = 149,597,870

Answer:

a. They are same side interior angles. Angle A measures 55°.

Step-by-step explanation:

They are the same side interior angles. Angle A measures 55°.

If you think about it, you'll see that when you add any of the interior angles of a triangle to its neighboring exterior angle, you always get 180 degrees a straight line.

Interior angles are those that lie inside a polygon. For example, a triangle has 3 interior angles. The other way to define interior angles is "angles enclosed in the interior region of two parallel lines when intersected by a transversal are known as interior angles".

Answer:

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

You can combine the two red shaded areas to get a larger portion with an angle of 120°.

The total degrees in a circle is 360° and since [tex]\frac{120}{360} =\frac{1}{3}[/tex],

The area of the combined red shaded area is [tex]\frac{1}{3}[/tex] of the entire area of the circle.

Thus, the probability of choosing the red shaded area is [tex]\frac{1}{3}[/tex]

Answer:

f(x) = |x| represents the modulus function or absolute value function. It gives us the distance between any point and the origin. Since distance can never be negative so we always consider its positive value only. You can simply multiply the given value with ‘-1’(if the given value is negative).

Answer:

So the value of s  = 7 cm

Step-by-step explanation:

We know that, Area of a triangle = 1/2 * b * h

So, base = 24 cm

height = s

Area = 1/2 * b * h

=>84 = 1/2 * 24 * h

=>84 = 12 * h

=>84 / 12 = h

=> 7 = h (in cm)

Answer is 0.2

Probability that a student who bought juice chosen at random purchased the grape flavor is 0.2.

According to the question, there are three lunch periods and the number of students that take different flavors of juice is shown below;

Since probability = Expected outcome/sample space

Sample space = 51 + 30 + 69 = 150

Probability that a student who bought juice chosen at random purchased the grape flavor = 30/150 = 0.2
