Answer:
Step-by-step explanation:
In a standard deck of cards, there are 52 cards. They are broken down into suits (4 of them: Spades, Hearts, Diamonds, Clubs) of 13 cards each. Each suit has 13 ordinal cards (A, 2 through 10, Jack, Queen, King).
Here we're asked to draw a card at random and find the probability of drawing either a diamond or a 7.
With probability, we look at the fraction of ways we can achieve some condition (the numerator) over the number of ways we can do something (the denominator).
Our denominator here is 52 - the number of cards from which we can pull 1.
Our numerator is both all the diamonds, 13 cards, and all the sevens, 4 cards, but we need to subtract 1 to account for the double counting of the 7 of diamonds.
In all we get:
13

It takes Rick, traveling 36mph, 40 minutes longer to go a certain distance than it takes Evelyn traveling at 84mph. Find the distance traveled
d = r · t and we know that the distance is the same.
Let x = time it takes Evelyn (in hours, since the rate is mph).
Evelyn's distance is 84x.
Rick's distance is 36·(x+2/3) since 40 minutes longer is 2/3 of an hour longer
84x = 36(x+2/3)
84x = 36x + 24
48x = 24
x = 1/2
So it takes Evelyn 1/2 an hour, meaning the distance is 84(1/2) = 42 miles
To confirm this, it would take Rick 42/36 hours or 1 and 1/6 hours. That's 70 minutes, which is 40 minutes longer than Evelyn's 1/2 hour trip.
The distance is 42 miles.

iii) ∠AOE + ∠DOE + ∠DOB = 180 {Straight line angles}
67 + ∠DOE + 100 = 180
∠DOE = 180 - 167
∠DOE = 13°
ii) ∠BOC = ∠AOD {Vertically opposite angles}
∠BOC = ∠AOE + ∠DOE
= 67 + 13
∠BOC = 80°
i) ∠AOC = ∠BOD
∠AOC = 100°

Answer:
Angle y = 60°

My name is Pauley the Parrot and I have a dilemma. Blackbeard found a
chest full of gold and he wanted to divide it evenly among the crew. The
chest weighed 12 pounds because it was filled to the top with gold. There
are 24 crew members (including myself and Blackbeard) on the boat. I told
him that if he gave each crew member 2 lbs. of gold there would be enough
to go around. Blackbeard said that he could give each crew member { lb of
gold and there would be enough to go around.
Can you help us figure out who is correct? Make sure to explain who was
correct, and why the other person was incorrect. Maybe, I can split my
earnings with you!

in 1/6 of an hour. How many lawns can Genesis
mow per hour?
Answer:
two lawns.....
...........
Genesis can mow 2 lawns per hour.
What is ratio?Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Genesis mows in 1/6 hour =1/3 lawns
To find, mow per hour,
∴ in 1/6 hours =1/3 lawn,
⇒1 hour = 6×1/3 lawn
⇒1 hour = 2 lawns.
So, In 1 hour, Genesis can mow 2 lawns.

Hamid needs to find the height of a parallelogram. The base is 3 inches long and the area is 30 square inches. What is the height?
Step 2 of 2: Finally, solve the problem by substituting in the appropriate values. (Round your answer to 2 decimal places if necessary.)
Answer:
the height is 10 inches
Step-by-step explanation:
area of a parallelogram is base times height
3h=30
divide both sides by 3
h=10
Answer:
area is base times height the base us 3 inches the area is 30 inches 3 times 10 is 30 so 10 is the height

describe how many stamps Holly can buy La x represents the number of books of stamps Holly buys. Find a
reasonable domain and range for the function.
Answer:
i think if she buys 5 books the she will have 90 stamps cuz 1 book cost 18 stamps then 5 books = 18x5=90

A new company president is said to have caused the company "to do a 180." Before the new president, the company was losing 10,000 per month .What is the company most likely doing under the new president?
Answer:
Earning 10,000 per month.
Step-by-step explanation:
Since a "180" usually refers to an opposite, the opposite of "losing 10,000 per month" would happen.
So, the company would be earning money instead of losing money.

Answer:
x = 3Sides are 6, 8 and 10Step-by-step explanation:
Use Pythagorean to find the value of x:
c² = a² + b²Consider:
a = x + 3, b = 3x - 1, c = 4x - 2Substitute and solve for x:
(4x - 2)² = (x + 3)² + (3x - 1)²16x² - 16x + 4 = x² + 6x + 9 + 9x² - 6x + 116x² - 10x² - 16x + 4 - 10 = 06x² - 16x - 6 = 03x² - 8x - 3 = 03x² - 9x + x - 3 = 03x(x - 3) + (x - 3) = 0(x - 3)(3x + 1) = 0x - 3 = 0, 3x + 1 = 0x = 3, x = - 1/3Positive root is accepted only.
Sides of the triangle:
a = x + 3 = 3 + 3 = 6b = 3x - 1 = 3*3 - 1 = 8c = 4x - 2 = 4*3 - 2 = 10solve for x and y then find the measurement of each angle
Answer:
x = 10
y = 40
Step-by-step explanation:
DE is a straight line so the sum of angles DBA and ABE is equal to 180
13x - 18 + 5x + 18 = 180 add like terms
18x = 180 divide both sides by 18
x = 10
Same rule applies when calculating value of y
3y - 52 + 2y + 32 = 180 add like terms
5y - 20 = 180 add 20 to both sides
5y = 200 divide both sides by 5
y = 40

Answer:
m=15
Step-by-step explanation:
since side QS is 9 and side AC is 6 which is 1.5 times bigger so there is a dilation of 1.5 meaning all sides are 1.5 times bigger on the right triangle than the left triangle. Side AB is 10 so 1.5 times 10 is 15 so m=15

Answer: y = -3x - 6
Step-by-step explanation:
One way to write a linear equation is with slope-intercept form. Slope-intercept form is y = mx + b, where m is the slope, and b is the y-intercept.
Thus, the equation is y = -3x - 6
Hope it helps :) and let me know if you are confused anywhere.
Answer:
y = -3x - 6
Step-by-step explanation:
Insert the information into the slope-intercept form equation:
y = mx + b
m = slopeb = y-intercept valueIn this instance, the slope is -3 and the y-intercept value is -6. Therefore, the equation of the line is y = -3x - 6
