Answer:
She needs to do at least 8 a day
Step-by-step explanation:
Answer: 7.066666666666666
Step-by-step explanation:
The answer really depends because it does not give me information about how many assignments he will do for each day so I will have to divide the total by the number of the days
106/15= 7.06666666666
it continues so I would say 7 and a half assignments but it sounds not good because it has a repeating decimal 6 in it
What we can do is we can tell the answer by saying Katy at least have to do at least 7 and a half or more assignments in order to finish all the missing assignments for both history and Math
Hope the explanation and the answer make sense

Answer:
1. -20 is the y intercept
2. 2x+4y=16
2x/2+4y/2=16/2
x+2y=8
x-x+2y=8-x
2y=-x+8
2y/2=-x/2+8/2
y=-x/2+4
4 is the y intercept
3. 2y+3x=7
2y+3x-3x=7-3x
2y=-3x+7
2y/2=-3x/2+7/2
y=-3
x/2+3.5
3.5 is the Y intercept
4. -3 is the y intercept
Step-by-step explanation:
Question 1:
y = -5x - 20
It is already in slope-intercept form, therefore the y-intercept is -20.
When y = 0, -5x - 20 = 0, x = -4.
Hence the x-intercept is -4.
Question 2:
2x + 4y = 16
When x = 0, 2(0) + 4y = 16, 4y = 16, y = 4.
The y-intercept is 4.
When y = 0, 2x + 4(0) = 16, 2x = 16, x = 8.
Hence the x-intercept is 8.
Question 3:
2y + 3x = 7
When x = 0, 2y + 3(0) = 7, 2y = 7, y = 3.5.
The y-intercept is 3.5.
When y = 0, 2(0) + 3x = 7, 3x = 7, x = 7/3.
Hence the x-intercept is 7/3.
Question 4:
It is ambiguous as the line marks on both of the axis are not labelled. However we assume each space is 1 unit.
Reading off the graph,
we have x-intercept is 3 and y-intercept is -3.
i just need y intercept and equation
Answer:
Slope = 4y-intercept = -8Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slope b is the y-interceptGiven the table
x y
2 0
7 20
Determining the slope between (2, 0) and (7, 20)
(x₁, y₁) = (2, 0)
(x₂, y₂) = (7, 20)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [20 - 0] / [7 - 2]
= 20 / 5
= 4
Thus, the slope of the line = m = 4
now substituting the point (2, 0) and the slope m = 4 in the slope-intercept form of a line equation to determine the y-intercept b.
[tex]y = mx+b[/tex]
0 = 4(2) + b
b + 8 = 0
subtract 8 from both sides
b + 8 - 8 = 0 - 8
b = -8
Thus, the y-intercept = -8
Summary:
Slope = 4y-intercept = -8write the linear equation in slope intercept form.
4x+y=1
Answer: y=-4x+1
Step-by-step explanation:
The slope-intercept form of a line is y=mx+b. Therefore, y needs to be on one side of the equation, and the x term and constant need to be on the other. Rearrange the equation to make this true:
4x+y=1
(4x+y)-4x=1-4x
y=1-4x
y=-4x+1

What is the perimeter of the following composite figure?
12 yd
9 yd
O 35.13 yd
O 21 yd
O 47.13 yd
O 42 yd
Answer:
C
Step-by-step explanation:
Here, we have a rectangle and a semi-circle and we want to calculate the area of the given shape
To get this, we add the area of the rectangle to the area of the semi-circle
The area of the rectangle is 12 * 9 = 108 square yard
From the diagram, we can see that 9 yards represent the diameter of the semi-circle
What we need to get the area of the semi-circle is the radius and this is half of the diameter
In this case, the half of the diameter is 9/2 = 4.5 yards
The area would be pi * r^2/2
= 3.142 * 4.5^2 = 63.6255/2 = 31.81275 square yards
We proceed to add this to the area of the rectangle
Mathematically, that would be ;
31.81275 + 108 = 139.81275 square yards
The closest answer here is 139.79 which we are going to select
The reason for the answer difference is the version of pi used
Pi could be 22/7 or 3.142
Using both will lead to different answers before approximation
Answer:
139.79 yd^2
108 + 31.79 = 139.79
Explanation:
Rectangle's Area
12 x 9 = 108
Semi Circle's Area
9 x 9 = 81
81 x 3.14 = 254.34
254.34/8 = 31.79
The semi circle's 2 formulas are πr^2/2 and πd^2/8.
Use πd^2/8 if you are using the diameter
the d stands for diameter
Use πr^2/2 if you are using the radius
the r stands for radius
This is what I used for the semi circle
3.14 x 9^2/8
You can also use this
3.14 x 4.5^2/2
Both of those work and you will get the same results.

25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple One marker is drawn out of the bag, then put back in. How many times would you expect a blue marker to be picked in 80 draws?
Answer: 16
Step-by-step explanation:
From the question, we are informed that there are 25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple and that one marker is drawn out of the bag, then put back in.
The probability of picking a blue marker will be: = 5/25 = 1/5
Therefore, the number of times that a blue marker will be expected to be picked in 80 draws would be:
= 1/5 × 80
= 16 times

You've been saving your allowance to buy some new video games you head to the mall to do some shopping you say that two stores are having a big sale on video games GameWorld is selling for video games for $68.00 Best Bargains is selling 6 video games for $99.00 If you only want to buy one video game which store will give you the better deal explain.
Answer: Best Bargains will give a better deal at $16.50 per game.
Step-by-step explanation:
You did not mention the number of games GameWorld was selling for $68.00 and that number is 4.
GameWorld is selling 4 games for $68.00. They are therefore selling one game for:
= 68/4
= $17.00 per game
Best Bargains is selling 6 video games for $99. Each game is:
= 99/6
= $16.50 per games
Best Bargains will give a better deal at $16.50 per game.

Step-by-step explanation:
Which events are independent? Select three options.
Roll a number cube, and then roll the same number cube again.
Flip a coin, and then flip the coin a second time.
Remove a card from a deck, and then remove a second card.
Draw a card from a deck, replace it, and then draw a second card.
Take a marble out of a bag, and then take a second marble out of the bag.
Answer: The first, second, and fourth.
Step-by-step explanation:
1). When you roll a cube twice, the number you get on the first roll doesn’t impact the second. As a result, it’s independent.
2). When you flip a coin twice, what you get on the first flip doesn’t impact what you get on the second. As a result, it’s independent.
3). When you remove a card from a deck, then remove a second one WITHOUT replacing the first, the first card impacts the second draw. For example, when I draw the first card, my chances of drawing a two are 1/13. If I draw a two the first time, my chances of drawing a two the second time are 1/17 (3/51. The total is fifty-one since one card is missing). Since the first draw impacted the probability of the second, the events are NOT independent.
4). When you remove a card, replace it, then draw again, your chances of drawing the same card doesn’t change. For example, my odds of drawing a three are 1/13 (or 4/52). If I draw a three the first time, then put it back and draw again, my odds are still 1/13 because I put the card back in the deck. As a result, the event is independent.
5). If I take a marble from a bag, and then take a second marble, the first draw impacts the second. For example, if a bag has three blue marbles and three green marbles, my chances of getting a blue marble the first time are 1/2 (or 3/6). If I get a blue marble and choose again, WITHOUT replacing it, my chances of choosing another blue marble are 2/5 (since one marble is missing). Since the first draw impacting the probability of the second, the events are NOT independent.

The sum of z₁ and z₂ is 3.
What are complex numbers?The sum of a real number and an imaginary number is called a complex number. A complex number is usually represented by z and has the form a + ib. Here, both a and b are real numbers. The real part, denoted by Re(z), is represented by the value "a," and the imaginary part, represented by "b," is represented by Im(z). Also known as an imaginary number, ib.
Given z₁ = 2 + √3i,
z₂ = 1 - √3i
to calculate the sum
z₁ + z₂ = 2 + √3i + 1 - √3i
sum of complex number is done by adding real part and imaginary part separately,
+ √3i and - √3i is canceled
z₁ + z₂ = 3 + 0i = 3
Hence the sum is 3.
