A person race walking a distance of 20 kilometers in 100 minutes is more faster with a speed of 0.2 kilometer per minutes.
How to determine who is faster?Mathematically, the speed of a physical object or body can be calculated by using this formula;
Speed = distance/time
Next, we would convert the unit of distance covered by the bird in miles to kilometers as follows:
1 mile = 1.60934 kilometer.
10,000 miles = X kilometer.
Cross-multiplying, we have:
X kilometer = 10,000 miles × 1.60934 kilometer.
X kilometer = 16,093.4 kilometer.
Also, we would convert the unit of time in days to minutes as follows:
1 day = 1,440 minutes
75 days = X minutes
Cross-multiplying, we have:
X minutes = 75 days × 1,440
X minutes = 108,000 minutes.
Now, we can calculate the speed of this bird as follows:
Speed = 16,093.4/108,000
Speed = 0.1490 kilometer per minutes.
For the speed of the person, we have:
Speed = 20/100
Speed = 0.2 kilometer per minutes.

Solve for b.
b - 14 = -10
A. b = -4
B. b = 4
C. b = -24
D. b = 24
The value of b after solution of the expression, b-14 = -10, is 4.
According to the question,
We have the following expression:
b-14 = -10
Now, we will first add 14 on both sides of the above equation:
b = -10+14
We know that when two integers are of different signs then the smaller number is subtracted from the larger number but the sign in the result is of the larger number.
So, in this case, 14 is larger than 10 then the result will be positive.
So, we have the following expression:
b = 4
Hence, the correct option is B.

a grocer wants to mix kenyan beans that sell for $8.25 per pound with venezuelan beans that sell for $9.50 per pound to form a 50 pound batch of beans that sells for $9.00 per pound. how many pounds of kenyan beans should go
into the blend?
Grocer will mix 20 pounds of the kenyan beans $8.25per/lb one and another 30 pounds of the venezuelan beans $9.50per/lb one.
Let's x be the kenyan beans that sell for $8.25 per pound and y be venezuelan beans that sell for $9.50 per pound.
Altogether there are 50 pounds of beans.
The algebraic equation would be x + y = 18.
At $9.00 per pound, he will make 50 * $9.00 = $ 450.0
So, how many of the x and y kinds of coffee should he use to make the $9.00 per pound mixture which will net him $450.0.
The algebraic equation would be 8.25x + 9.50y = 450
We now have two equations
x + y = 50 --(i)
8.25x + 9.50y = 450 --(ii)
Substituting x= 50 - y in the second equation gives us
8.25(50-y) + 9.50y = 450
412.5 - 8.25y + 9.50y = 450
1.25y = 450 - 412.5
1.25y = 37.5
y = 30
Substitute the value of y in equation(i)
x + y = 50
x = 50 - 30
x = 20
Hence, Grocer will mix 20 pounds of the kenyan beans $8.25per/lb one and another 30 pounds of the venezuelan beans $9.50per/lb one.

The number of short sleeves that Maria sold is 819.
What is ratio?Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them.
In this case, Maria’s clothing store sold 1547 shirts with the ratio of short sleeve to long sleeve shirt being 9:8.
The number of short sleeves will be:
= Ratio for short sleeve / Total ratio × Total number of clothes
= 9 / (8 + 9) × 1547

According to the concept of unitary method, the number of pennies are 6.
Unitary method:
The process of finding the value of a single unit, and based on this value is called as unitary method.
Given,
Out of 150 coins, 90 are quarters. Of the remaining coins, 40% are nickels and the rest are dimes and pennies. There are 5 dimes for every penny.
Here we need to find the number of pennies in the coins.
Here we know that the total number of coins are 150, thus includes
=> Quarters + nickels + dimes + pennies = 150
Here the number of Quarters are 90
Therefore, the remaining coins are calculated as,
=> 150 − 90 = 60
Here the percent of nickels is 40, then the number of nickels is
=> 60x 40/100
=> 24 numbers
Now, the remaining coins such as dimes and pennies are
=> 60 − 24 = 36 numbers.
Here we know that, in (5 + 1) = 6 coin of dimes and pennies there is 1 penny
So, in 36 coin of dimes and pennies there are,
=>36 / 6
=> 6
Therefore, there are 6 pennies.

Chase is filing as a single individual for the year 2018 and has a total taxable income of $91,630. If he is in the 24% tax bracket, where the federal income tax owed is $14,089.50 plus 24% of every dollar above $82,500, how much does Chase owe in federal income taxes for 2018? Round your answer to the nearest cent. Do NOT round until you calculate the final answer.
In the year 2018, the amount that Chase owes in federal income taxes is $16, 280.70
How to find the federal income taxes?In 2018, Chase earned $91, 630 which put him in the 24% tax bracket. Here, his tax is $14,089.50 plus 24% of every dollar above $82,500.
The amount that Chase made above $82, 500 is:
= 91, 630 - 82, 500
= $9, 130
The federal income tax that Chase owes is therefore:
= 14, 089.50 + (9, 130 x 24%)
= 14, 089.50 + $2, 191. 20
= $16, 280.70

Answer: $16,280.70
Step-by-step explanation:
First, find the difference between $91,630 and $82,500 to find the amount that is taxed at the 24% tax rate.
$91,630−$82,500=$9,130
Now, multiply $9,130 by 24% to find the additional amount of tax.
$9,130⋅24%=$2,191.20
Add $2,191.20 to $14,089.50 to find the total amount of federal income taxes Chase owes.
$2,191.20+$14,089.50=$16,280.70
Therefore, Chase owes $16,280.70 in federal income taxes for 2018.

Step-by-step explanation:
Answer:
m∠1 = 50°
Step-by-step explanation:
From inspection of the given diagram we can see that angle 1, angle 40° and a right angle are the interior angles of a right triangle.
As the interior angles of a triangle sum to 180°:
⇒ m∠1 + 40° + 90° = 180°
⇒ m∠1 + 130° = 180°
⇒ m∠1 + 130° - 130° = 180° - 130°
⇒ m∠1 = 50°
Therefore, the measure of angle 1 is 50°.
