Answer:

11.3

Step-by-step explanation:

In a right angled triangle:  the square of the hypotenuse is equal to

the sum of the squares of the other two sides.

[tex]8^{2} + 8^{2} = x^{2}[/tex] (x is the hypotenuse)

64 + 64 = [tex]x^{2}[/tex]

[tex]x^{2}[/tex] = 128

=> x = [tex]\sqrt{128}[/tex] = 11.3137085 = 11.3

Jaira is having pizza for her birthday party. She can make two small pizzas, each with a radius of 6 inches, or one large pizza with a radius of 12 inches. Which option will give her more square inches of pizza?

Answers

Answer: One large pizza with a radius of 12 inches

Step-by-step explanation:

Hi, to answer this question we have to calculate the area of each option.

Area of a circle: π r^2  

Option 1: two small pizzas, each with a radius of 6 inches.

A = π r^2 = π 6^2 = 113.1 in2

Since there are 2 small pizzas we have to multiply the area by 2:

113.2 x 2 = 226.2 in2

Option2 = one large pizza with a radius of 12 inches

A = π r^2 = π 12^2 = 452.38 in2

Since 452.38 in2 > 113.1 in2

Option 2 (one large pizza) will give her more square inches of pizza

elijah's credit card statement showed these items: Last Balance Payments Finance Rate New Charges $152.58 $45.00 1.5% $213.40 What is Elijah's new balance? $320.98 $322.59 $323.27 $397.51

Answers

Answer:

Option A,$320.98  is correct

Step-by-step explanation:

The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.

last balance as shown by the statement was $152.58

new charges were $213.40

payment made by Elijah was  $45

new balance=$152.58+$213.40-$45=$320.98

The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.

Answer:

Other answer is incorrect. Elijah's new balance would be $322.59

A bag contains 3 red, 4 blue, and 6 yellow marbles. One marble is selected at a time, and once a marble is selected, it is replaced. Find each probability. P(red and yellow)

Answers

Answer:

red = 3/13

yellow = 6/13

blue= 4/13

Step-by-step explanation:

breainliest really needed!!

The probability of selecting the red marble and yellow marble is 18/169.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, a bag contains 3 red, 4 blue, and 6 yellow marbles.

Total number of outcomes = 3+4+6=13

Probability of selecting red marble = 3/13

Probability of selecting yellow marble = 6/13

So, P(red and yellow) = 3/13 × 6/13

= 18/169

Therefore, the probability of selecting the red marble and yellow marble is 18/169.

Show the Euler-Descartes formula holds for the Great Pyramid of Cheops

Answers

Answer:

For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula

Step-by-step explanation:

The great pyramid of Cheops is a square based pyramid therefore we have;

V + F = E + 2

Where:

V = Vertices

F = Faces

E = Edges

Hence, we have for a square pyramid;

V = 5 vertices (One at the peak, and four  at the base edges)

F = 5 faces (The four lateral or side faces and the base)

E = 8 edges ( The four lateral edges and the four base edges)

Hence;

5 + 5 = 8 + 2 which proves Euler-Descartes formula.

listening to very loud music at a sound intensity level of 10 on her headphones. How many times louder is Braylee's music

than Jessica's?

Answers

Answer:

Option A is correct.

Braylee's music is 3 times louder than Jessica's.

Step-by-step explanation:

Full Complete Questions

The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as

L = 10log (I/I₀), where lo = 10⁻¹² W/m²

and is the least intense sound a human ear can hear.

Jessica is listening to soft music at a sound intensity level of 10⁻⁹ W/m² on her computer while she does her homework.

Braylee is completing her homework while listening to very loud music at a sound intensity level of 10⁻³ W/m² on her headphones. How many times louder is Braylee’s music than Jessica’s?

times louder

3 times louder

30 times louder

90 times louder

Solution

The loudness of a sound intensity is given as

L = 10 log (I/I₀)

For Jessica

I = 10⁻⁹ W/m²

I₀ = 10⁻¹² W/m²

L = 10 log (10⁻⁹/10⁻¹²)

L = 10 log (10³)

L = 10 × 3 = 30 dB

For Braylee

I = 10⁻³ W/m²

I₀ = 10⁻¹² W/m²

L = 10 log (10⁻³/10⁻¹²)

L = 10 log (10⁹)

L = 10 × 9 = 90 dB

How many times louder is Braylee's music than Jessica's?

The factor by which Braylee's music is louder than Jessica's = (90/30) = 3

Braylee's music is 3 times louder than Jessica's.

Find the next two terms of the sequence:
2050, 1990, 1930, 1870, 1810, 1750
The next two terms of the sequence are

Answers

Answer:

The answer is 1690, and then 1630

Step-by-step explanation:

2050, 1990, 1930, 1870, 1810, 1750, 1690, 1630

Each number is going down by 60

Answer: The next two terms are 1690 and 1630 in that order

===============================================================

Explanation:

This is an arithmetic sequence. We are adding -60 to each term to get the next term. Put another way, we are subtracting 60 from each term to get the next.

term 1 = 2050

term 2 = (term1) + (-60) = (term1) - 60 = 2050 - 60 = 1990

term 3 = (term2) + (-60) = (term2) - 60 = 1990 - 60 = 1930

term 4 = (term3) + (-60) = (term3) - 60 = 1930 - 60 = 1870

and so on

Keeping this pattern up, we get these next two terms

1750 - 60 = 1690

1690 - 60 = 1630

which are the two answers

-----------

If you want to use a formula, then a1 = 2050 is the first term and d = -60 is the common difference. We get this nth term formula

a(n) = a1 + d(n-1)

a(n) = 2050 + (-60)(n-1)

a(n) = 2050 - 60n + 60

a(n) = -60n + 2110

Then note that six terms of the sequence are given to us. This means we want to find the 7th term, so we plug in n = 7 to get

a(n) = -60n + 2110

a(7) = -60(7) + 2110

a(7) = -420 + 2110

a(7) = 1690

The 7th term is 1690

Repeat for n = 8

a(n) = -60n + 2110

a(8) = -60(8) + 2110

a(8) = -480 + 2110

a(8) = 1630

The 8th term is 1630
