Answer:
the probability of a red card is 1/2 of 50% chance. The chance of a diamond card is 1/4 or 25% chance
Step-by-step explanation:
Answer as a fraction = 1/8
Answer in decimal form = 0.125
Answer as a percentage = 12.5%
==========================================
Explanation:
The probability of choosing a red card is 1/2 since half of the cards are red (the other half are black).
This card is selected and then put back into the deck. This means that the second selection will deal with the same number of total cards.
Since we have four suits, and one of those suits is diamonds, this means the probability of choosing a diamond card is 1/4.
We then multiply the fractions to get (1/2)*(1/4) = (1*1)/(2*4) = 1/8
The probability of getting a red card first, then a diamond card second, is 1/8
Use your calculator to find that 1/8 = 0.125 which converts to the percent form 12.5%

In the diagram Shown a 2-foot wide flower border surrounds the heart-shaped pond. What is the area of the border?
!!PLEASE HELP!!
Answer:
Step-by-step explanation:
Area of square = 144 sq ft
Area of circle = πr² = 36π sq ft
Total area = (144+36π) sq ft
Square section of pond is 10 ft by 10 ft, area = 100 sq ft
Circular area of pond has diameter of 8 ft.
Area = πr² = 16π sq ft
Area of pond = (100+16π) sq ft
Area of border = (144+36π)-(100+16π) = (44+20π) sq ft

Answer:
21
Step-by-step explanation:
straight line = 180 degrees ( H,D,R)
180 = 7x - 3 + 2x - 6
180 = 7x + 2x - 3 - 6 (group the same type number together)
180 = 9x -9 (simplify the numbers)
189 = 9x (+9)
21 = x (divide by 9)

There are 40 working hours in a week and 52 weeks a year. How much does Nate need to make an hour to stay out of debt if it costs him $900 to live each month?
Answer: $5.19
Step-by-step explanation:
If there are 40 working hours in a week and 52 weeks in a year, 40 * 52 should be the amount of working hours in a year.
40 * 52 = 2080 working hours
Nate needs $900 to live each month and there are 12 months in a year, so $900 * 12 would equal how much he spends per year.
$900 * 12 = $10800
Divide $10800 by 2080 working hours to get how much he needs to make per working hour.
10800/2080 = approximately 5.19, rounded down from the nearest hundredth
He needs to make $5.19 per hour, so the answer is the last option.

The difference of a number c and 17 is more than 33.
Answer:
c-17=x>33
c=51
Step-by-step explanation:
The value of number c should be greater than 50.
It is given that difference of a number c and 17 is more than 33.
We have to find out the value of number c.
What do you mean by algebraic expressions ?
The algebraic expressions are those which are made up of variables, constants and algebraic operations i.e., addition, subtraction, etc.
As per the question ;
The difference of c and 17 is more than 33.
i.e.,
difference of c and 17 meant ; 17 should be subtracted from c and this is greater than 33.
i.e.,
c - 17 > 33
c > 33 + 17
c > 50
Thus , the value of number c should be greater than 50.

Answer: C: cubic expression
Step-by-step explanation:
Classify the expression: 5x³ + 2x − 3
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
so
a) By the number of terms is a trinomial, because has three terms
b) By their degree The degree of the polynomial is found by looking at the term with the highest exponent on its variable
The highest exponent is 3 so this is a 3rd degree trinomial
therefore
Is a cubic expression

The Harvey family stayed at a hotel for n nights. The cost was $80 per night plus a one-time fee of $20 because they brought their dog. Which expression represent the total cost of their hotel stay.
80n + 20n
80n + 20
80 + 20n
80 + 20 + n
Answer:
80n + 20
Step-by-step explanation:
20 stays the same because it's a one time fee. Then, for every night the Harvey family stays, it costs them eighty dollars. So, it's 80n + 20
Answer: 80n+20
Step-by-step explanation:
80 is the cost of nights you stayed but you don’t know the number of nights they dated so you place n next to 80 and they payed an additional 20 fee so you add that to 80n
A Mars rover descended from the rim of a crater at a constant rate. After 2 days, the rover's elevation was 106 meters. After 6 days, its elevation was 48 meters. What elevation did the rover start at? ____meters Complete the equation that describes the relationship between the rover's elevation in meters, E, and the elapsed time in days, t. Write your answer using whole numbers or decimals rounded to the nearest tenth. E= ___ t+____
Answer:
135
E = - 14.5t + 135
Step-by-step explanation:
Given that, descent rate is constant ;
Elevation after 2 days = 106 m
Elevation after 6 days = 48 m
Let
Rate of elevation per day= x
Initial elevation = a
Hence,
a - 2x = 106 - - - (1)
a - 6x = 48 ___(2)
-2x + 6x = 106 - 48
4x = 58
x = 58/4
x = 14.5 meters per day
Hence, initial elevation :
a - 2(14.5) = 106
a - 29 = 106
a = 106 + 29
a = 135
Relationship between Rover's elevation, E and elapsed time, t
E = - 14.5t + 135
-14.5 = rate per day
