Answer:
-12u+8w+16
Step-by-step explanation:
to get rid of the parenthesis you multiply everything that is inside of the parenthesis by -4
-4x3u=-12u
-4x-2w=8w
-4x-4=16
then we just add everything together and end with
-12u+8w+16

Answer:
-18, -12, 0, 25, 5
0, -12, 5, -18, 25
25, 0, -18, 5, -12
-12, 25, 5, 0, -18
5, -18, 25, -12, 0
Step-by-step explanation:
The only values you need to use here are 0, 5, 25, -12, and -18.
I started with the bottom right box because the far right column only had one empty box. From the set of values I stated above, that column already had each of those numbers except for 0, so 0 would go in the bottom right box.
Another way to think about it is each row or column must have a 5 and a 25 to make 30, and a -12 and a -18 to make -30. Those two numbers cancel each other out to make 0, and then each row/column will include a 0 value which obviously wouldn't effect that balance. So the whole row/column will come out to be 0.
After figuring out that first bottom right box, go to the next row/column with only one empty box left (this happened to be the very bottom row), and use the same strategy to fill in the missing value.
Continue finding the next row/column with only one empty box left and figure out its missing value until you've completed the whole box.

Write an equation that can be used to answer the question. Then solve. Round to the nearest tenth if necessary.
Answer:
5^2+h^2=12^2, the answer would be ~10.97 ft.
Step-by-step explanation:
I would use the Pythagorean theorem to solve this problem. Put in the things that you know, so in this image we are given one of the legs and the hypotenuse of the triangle.
Pythagorean theorem is :
a^2+b^2=c^2 with a and b being the legs and c being the hypotenuse.
Once you plug in the hypotenuse and one of the legs, solve for the other leg by subtracting a^2 (5^2) from 12^2 (c^2), which will give you 119, and then take the square root of 119 and you will get your answer.

Jon is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by h(t)=5+25t-16t^2, where t is the time in seconds.
a) How much time will pass before Jon hits the ball? (round to the nearest tenth of a second)
b) What is the time in which the maximum height the ball attains? ( to the nearest hundredth of a second)
Answer: A= 1.60 sec
And I am not sure if B is correct, but I got 14.77 ft.
Step-by-step explanation:
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Jon who is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by -
h(t) = 5 + 25t - 16t²
where [t] is the time in seconds.
[A] -
At h = 4ft, we can write -
4 = 5 + 25t - 16t²
- 16t² + 25t + 1 = 0
On solving, we get -
t = 1.602 seconds
[B] -
We have -
h(t) = 5 + 25t - 16t²
For maximum height -
dh/dt = 0
d/dt(5 + 25t - 16t²) = 0
0 + 25 - 32t = 0
32t = 25
t = 25/32
t = 0.79 seconds
Therefore -
t = 1.602 seconds will pass before Jon hits the ball.At t = 0.79 seconds the ball attains maximum height.To solve more questions on Equation Modelling, visit the link below -

Step-by-step explanation:
each bracelet takes 15 min
15*3=45
1 hour = 60 minutes..
In 1 hour she makes 4
In 2 hours (120 minutes) she makes 8
So in each hour she makes 4 ( 8 /2 = 4)
So In 3 hours she will make 3 x 4 = 12 bracelets

Complete the statements about the system of linear equations represented by the tables.
The equation representing the left table is
.
The equation representing the right table is
.
The solution to the system of equations is
Answer:
The equation representing the left table is:
y = 1.5x – 6
The equation representing the right table is:
y = –4x + 6.1
The solution to the system of equations is:
(2.2, –2.7)
Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The first table is
x y
0 -6
1 -4.5
2 -3
3 -1.5
Slope = -4.5+6/1
=1.5
Now let us find y intercept
-6=1.5(0)+b
-6=b
So the equation representing the left table is y=1.5x-6
Now let us find second table
x y
0 6.1
1 2.1
2 -1.9
3 -5.9
m=2.1-6.1/1=-4
Now y intercept
2.1=-4+b
b=2.1+4
b=6.1
Equation representing the right table is y=-4x+6.1
Now equate two equations
1.5x-6=-4x+6.1
1.5x+4x=6.1+6
5.5x=12.1
x=12.1/5.5
x=2.2
and y=-4(2.2)+6.1
y=-8.8+6.1
y=-2.7
Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

A triangle has a base of 10 centimeters and a height of 12 centimeters. A rectangle has a base of 10 centimeters and a height of 12 centimeters.
What are the areas of the figures?
The area of the triangle is
___ cm2.
The area of the rectangle is
___ cm2.
The area of the triangle is
60 cm2.
The area of the rectangle is
240 cm2.
In a two-dimensional plane, an area of triangle is equal to the sum of the areas of its three sides.
To calculate a rectangle's area, count the number of square units that fit within the rectangle's perimeter.
Area of triangle = h x b / 2
Given
h = 12
b =10
hence
A= h x b / 2
= 12 x 10 / 2
= 120 / 2
= 60 cm2
Area of rectangle = l x b

Leigh-Anne invests £2500 for 4 years in a savings account.
She gets 3% per annum compound interest.
How much money does Leigh-Anne have at the end of 4 years.
Answer:
After 4 years, Leigh-Anne will have £ 2,813.77 in her account.
Step-by-step explanation:
Given that Leigh-Anne invests £ 2500 for 4 years in a savings account, and she gets 3% per annum compound interest, to determine how much money does Leigh-Anne have at the end of 4 years, the following calculation must be performed:
X = 2,500 x (1 + 0.03 / 1) ^ 4
X = (2,500 x 1,003) ^ 4
X = 2,813.77
Thus, after 4 years, Leigh-Anne will have £ 2,813.77 in her account.

The bronx zoo opened at 9.00 am. In the first hour 280 people purchased admission tickets. In the second hour 25 percent more people purchased admission people than the first hour . Each ticket cost 16.25. What was the total amount of money paid for all the tickets purchased in the first two hours
Answer:
Total amount paid for tickets in the two hours = $10,237.50
Step-by-step explanation:
Step 1
Ist Hour, 280 tickets were sold at the cost of $16.25
Amount of money made in the first hour= Number of people who purchased ticket x price of a ticket
=280 x 16.25 =$4,550
2nd Hour, 25 % more people purchased ,
which means the total number of people who purchased tickets =
1.25 x 280= 350
Amount of money made in second hour = Number of people who purchased ticket x price of a ticket 350 x 16.25 =$5,687.5
Step 2
Total amount paid for tickets in the two hours = Amount of money made in the first hour +Amount of money made in second hour
=$4,550+ $5,687.5
=$10,237.50

A square is cut diagonally into two equal parts. If each part has an area of 50 cm2, then what is the perimeter of each part?
Answer:
30cm
Step-by-step explanation:
Given data
When are square is cut diagonally into two parts
The resulting shape is a triangle
hence the area of the square = 50+50 = 100cm^2
The length of each side of the square = √100= 10cm
likewise the diagonal of the square = 10cm
Hence the perimeter of the resulting triangle= 10+10+10= 30cm
