3 of the 6 sides that exist on a dice have odd numbers.
Answer:
1/2 probability of getting an odd number
Step-by-step explanation:
Dice have the given outcomes of getting a 1, 2, 3, 4, 5, or 6. Considering that the desired outcomes are only 3 out of 6 of those given outcomes, that leaves us with a 3/6 or 1/2 chance of getting an odd number.

A circular region has population of about 15,500 people and a population density of about 775 people per square kilometer find the radius of the region
Answer:
Radius of the region = 2.5 km (Approx)
Step-by-step explanation:
Given:
Total population = 15,500
Density = 775 people per square kilo meter
Find:
Radius of the region
Computation:
Total ares = 15,500 / 775
Total ares = 20 km
Total ares = πr²
20 = (22/7)r²
r² = 6.363636
r = 2.52
Radius of the region = 2.5 km (Approx)

Bill and gwyll are going on holiday to the USA. Bill changes £450 into $729 Gwyll changes £500 into $780 What exchange rate did bill get? What exchange rate did Gwyll get?
Answer:
Bill's exchange rate was $1 to £1.62
Gwyll's exchange rate was $1 to £1.56
Step-by-step explanation:
Given
Bill changed £450 into $729
Gwyll changes £500 into $780
Required
Determine their exchange rates
Exchange rate is calculated by dividing the currencies against one another.
Given that they both changed from pound to dollar, the exchange rate is calculated as thus;
[tex]Rate = \frac{Amount\ in\ pound}{Amount\ in\ dollar}[/tex]
Calculating Bill's Exchange Rate
[tex]Rate = \frac{\£729}{\$450}[/tex]
[tex]Rate = \frac{\£1.62}{\$1}[/tex]
Represent as a ratio
[tex]Rate = \£1.62:\$1[/tex]
Hence, Bill's exchange rate was $1 to £1.62
Calculating Gwyll's Exchange Rate, using the same formula and steps
[tex]Rate = \frac{\£780}{\$500}[/tex]
[tex]Rate = \frac{\£1.56}{\$1}[/tex]
Represent as a ratio
[tex]Rate = \£1.56:\$1[/tex]
Hence, Gwyll's exchange rate was $1 to £1.56
Amanda Roberts works a Monday through Friday work week at a rate of $8.75 per hour. She takes a 1- hour lunch break. If she clocks in each day at 8:45 am and leaves at 5:15 pm, what is her total pay for the week?
Answer:
$328.13
Step-by-step explanation:
First, find the amount of time she works every day.
Between 8:45 and 5:15, there are 8.5 hours.
Subtract 1 for her lunch break, so there are 7.5 hours worked every day
Then, calculate how much she gets every day:
7.5(8.75)
= $65.625
Multiply this by 5 to find her pay for the week:
65.625(5)
= $328.13 is her total pay for the week
The total pay for the week will be $318.75.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Amanda Roberts works a Monday through Friday work week at a rate of $8.75 per hour. She takes a 1- hour lunch break. If she clocks in each day at 8:45 am and leaves at 5:15 pm.
The number of hours from 8:45 am to 5:15 pm will be 8.5 hours.
And the number of working days will be 5.
Then the total pay for the week will be
⇒ $8.75 x 5 x (8.5 - 1)
⇒ $8.75 x 5 x 7.5
⇒ $318.75
The total pay for the week will be $318.75.

Ues the diagrams to solve for x and y.
please try to explain too please
Answer:
y=4 , x= 12
Step-by-step explanation:
This question deals with linear equations so, with this problem, subsitution is the easiest form of solving.
x + y = 16
8 + y = x
Now you know that x = 8 + y, so replace it in the opposing equation.
8 + y + y = 16 (simplfy)
8 + 2y = 16 (subtract 8 from each side)
2y = 8 (divide each side by 2)
y = 4
plug into other formula
8 + 4 = x
x =12
Answer:
y=4 , x= 12
Step-by-step explanation:
x + y = 16
8 + y = x
8 + y + y = 16 (simplfy)
8 + 2y = 16 (subtract 8 from each side)
2y = 8 (divide each side by 2)
y = 4
8 + 4 = x
x =12

Answer:
[tex]x = - \frac{3}{2} \: \: \: or \: \: - 1.5[/tex]Step-by-step explanation:
1.6(15x + 25)= -6x -5
Multiply the terms
That's
24x + 40 = - 6x - 5
Add 6x to both sides
24x + 6x + 40 = 6x - 6x - 5
30x + 40 = - 5
Subtract 40 from both sides
That's
30x + 40 - 40 = - 5 - 40
30x = - 45
Divide both sides by 30
We have the final answer as

In the Mississippi River Delta, fresh water (0% salinity) mixes with salt water from the Gulf of Mexico (3 1 2% salinity). If 1,000 gallons of river water mixes with 3,000 gallons from the Gulf, how many gallons result, and what is its percent salinity? (Estimate a reasonable percent range for your answer before you solve.)
Answer:
The total resulting gallons of water is 4,000 gallons
The concentration of the resulting solution is 2.625% salinity
Step-by-step explanation:
The salinity of the fresh water from the Mississippi River Delta = 0%
The salinity of the water from the Gulf of Mexico = 3 1/2%
Therefore, if 1,000 gallons of river water mixes with 3,000 gallons from the Gulf, we have;
The total resulting gallons of water = 1,000 + 3,000 = 4,000 gallons
The total resulting gallons of water = 4,000 gallons
The concentration of the resulting solution is found as follows;
The concentration of the resulting solution = (3 × 3 1/2)/400 × 100 = 2.625%
The concentration of the resulting solution = 2.625% salinity.
Dwayne had 136 songs on his phone. He deleted 56 songs. What is the
ratio of songs he kept to songs he deleted in its simplest form)?
Answer:
10 : 7
Step-by-step explanation:
Deleting 56 songs leaves 136 - 56 = 80 songs, thus
ratio of songs kept : songs deleted = 80 : 56 ( divide both parts by 8 )
80 : 56 = 10 : 7 ← in simplest form
What are the first five multiples of 12?
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
A multiple is a number that can be divided by that number with no remainder. For example, multiples of 5 are 5, 10, 15, and 20.
A multiple of 12 is basically 12 × (number of multiple), for example, if you want the second multiple of 12, you would multiply 2 by 12.
So multiply 12 by 1, 2, 3, 4, and 5.
12×1=12
12×2=24
12×3=36
12×4=48
12×5=60
The first five multiples of 12 are 12, 24, 36, 48, and 60.

Group of answer choices

30˚-60˚-90˚
None of the above
45˚-45˚-90˚
Answer:
The correct option is;
30° - 60° - 90°
Step-by-step explanation:
Rotation is one of the three rigid transformation of which others are reflection and translation. In a rotation transformation of a figure about a fixed point, known as the center of rotation, the figure is turned in a circular path about the fixed point or center of rotation. The size and shape of the pre-image the rotation are the same however, depending on the angle of rotation, their facing directions may be different. The specification of a rotation can be in the clockwise direction or in the anti-clockwise direction
The shape of the triangle in the question and the image are the same and are therefore congruent. All interior angles of the triangle and those of its rotation will therefore be congruent.

she should buy the yearly pass.
What is the fewest number of visits Maya must make to the pool so that the yearly pass will be less expensive than paying $6.00 per visit?
Answer: 31 times
Step-by-step explanation:
The way solve the problem is, you multiply $6.00 by 31 ( How I did it I multiply a lot of numbers by $6.00...) and you get $186.00. now 6 cannot fit in any further you have the cost, and the number of times Maya can go, without paying for the pass.
Kevin is looking for a job as a graphic designer. One ad lists a job that pays 64.6K. Another job he found has a weekly salary of $1,120. What is the difference in the weekly salaries of these two jobs? Round to the nearest dollar.
Answer:
The difference between the two weekly salaries is $122
Step-by-step explanation:
One job pays $64,600 per year. Since there are 52 weeks in a year, the weekly salary for this job is the quotient: $64600/52 = $1242.31 which rounded to the nearest dollar gives: $1242 per week
The other job pays $1120 per week. Therefore the difference in weekly salary for the two is:
$1242 - $1120 = $122
