Brenda bought a new computer for $380. She made a payment of $140 and got a discount of $30. Her mother paid 1/2 of the balance. How much does Brenda have left to pay?
Answer:
She needs to pay $20 more.
Step-by-step explanation:
Mothers payment: $360 divided by 2 = $190 left for Brenda
Brenda + discount payments: $190 - $140 = $50
$50 - $30 discount = $20

Answer:
x = 135°
Step-by-step explanation:
Hello!
The measure of Angle x is simply the sum of the other angles, JGH, and FGJ.
Solve for x:
x = JGH + FGJx = 60° + 75°x = 135°The value of x is 135°

Answer: You will need 1080 in²
Step-by-step explanation:
The formula for finding the area of a triangle is:
Area = 1/2 x b x h
b = base length
h = height
So the equation would be:
1/2 x 12 x 30 = 180
After finding our answer of 180 we multiply it by the amount of pennants we want to hang in this case that number is 6
180 x 6 = 1080
That's how we arrive at our answer of 1080 in².

Answer: 105 in^2
Step-by-step explanation: The area of the square is 25 because 5x5=25. The area of each triangle is 20, because to find a triangle it is BxH/2. so 5x8/2=20. Multiply this by four because there are four triangles and add the area of the square. So 20x4= 80. 80+25=105
40. If three dice are tossed, find the probability that the sum is less than 16.
Answer:
0.953703703704
Step-by-step explanation:
We have 6 × 6 × 6 = 216 possible results
You can make a table :
obtaining a sum of 18 in only one case : (6 ,6 ,6)
obtaining a sum of 17 in 3 cases : (5 ,6 ,6) ; (6 ,5 ,6) ; (6 ,6 ,5)
obtaining a sum of 16 in 6 cases : (5 ,5 ,6) ; (6 ,5 ,5) ; (5 ,6 ,5)
(4 ,6 ,6) ; (6 ,4 ,6) ; (6 ,6 ,4)
[tex]\text{the probability that the sum is less than 16} =\frac{216-\left( 1+3+6\right) }{216} = \frac{206}{216} =0.953703703704[/tex]

Mathew is a financial analyst for a surf board company. He has found an equation for the revenue of selling t-shirts with the company logo to be r= -3p^2 + 60p +1060, where p is the price of the company’s product. What should he use to determine the price of maximum sales?
Answer: The price of maximum sales is $160
Step-by-step explanation:
This question requires you to find the vertex of this equation. The vertex of a parabola is the point where the parabola crosses its axis of symmetry.
since the coefficient of the [tex]x^2[/tex] term is negative, the vertex will be the highest point on the graph.
this quadratic equation is in standard form: [tex]y = ax^2+bx+c[/tex].
From this, we can derive:
[tex]a = -3[/tex]
[tex]b = 60[/tex]
[tex]c = 1060[/tex]
First, determine the axis of symmetry ([tex]p[/tex] is the variable for the horizontal axis ([tex]x[/tex]) in this instance). This will be our x-coordinate of the vertex.
[tex]p = \frac{-b}{2a}[/tex]
[tex]p = \frac{-(60)}{2(-3)}[/tex]
[tex]p = \frac{-60}{-6}[/tex]
[tex]p=10[/tex]
Then, substitute the axis of symmetry into the function to find the y coordinate of the axis of symmetry. r stands for the variable for the vertical axis in this instance. This will be our y-coordinate of the vertex.
[tex]r = -3(10)^2+60(10)+1060[/tex]
[tex]r = 160[/tex]
As we have determined both the x and y coordinate of the vertex for this equation, we can determine that the maximum point is at [tex](10, 160)[/tex].
the maximum price ([tex]r[/tex]) is 160

To understand how to do this problem, we have to look at examples to figure it out. One example would be, if I had a whole cake and cut into 2 pieces I would have two halves, and if I cut it into 4 pieces, I'll have 4 quarters of cake, so 2/2 (two halves) = 4/4 (4 quarters). If I ate 1/2 I would have
(Keep in mind that Equivalent fractions are fractions that are equal to each other)
So to solve these we have to figure out the equal fractions. To do this, we start by multiplying by 2.
(the * symbol is multiplication)
So 3/4 would be 3*2=6 and 4*2=8 so it would be 6/8
Now we can try multiplying it by 3
3*3=9 and 4*3=12 so the 2nd would be 9/12
And we multiply it by 4 now,
3*4=12 and 4*4=16 so the 3th would be 12/16
So, therefore, the answers for 3/4 are 6/8, 9/12, & 12/16.
I'm also going to give you a simplified number that you can use to solve the other problems easier.
3/7 is 3/7. (cannot be simplified)
18/27 is 2/3.
20/80 is 1/4.
You can use these three numbers to start and multiply by 2 and 3 for the other two numbers.
I just gave you a very easy was to solve them and a simple calculator or doing the simple math will be able to help you figure out the rest.
Good luck!

help pls The circumference of the hub cap of a tire is 80.1 centimeters. Find the area of this hub cap. Use 3.14 for pi. Use pencil and paper. If the circumference of the hub cap were smaller, explain how this would change the area of the hub cap.
Answer: The area is 510.25 cm². If the circumference of the cap were smaller then the area would be smaller as well
Step-by-step explanation:
First, you must find the radius
80.1 ÷ 3.14 = 25.5
25.5 ÷ 2 = 12.75 <---- radius
Then from that, you find the area
A=πr²
12.75² = 162.5
162.5 × 3.24 = 510.25
Hope this was helpful!
Answer:
510.25 cm².
Step-by-step explanation:
First, your gonna need to find the radius before continuing
80.1 ÷ 3.14 = 25.5
25.5 ÷ 2 = 12.75
Find the area
A=πr²
12.75² = 162.5
162.5 × 3.24 = 510.25

The diagonal of square A, marked off by the red stars, is where the concession stand is. A local high school band is performing at the outdoor theater on a summer evening. The band has a school banner that is 40-feet long, and band members would like to hang it across the concession stand to let people know they are performing. Estimate the length of the concession stand to determine if the school banner can fit across the length of the concession stand. Show your work and explain your reasoning.
Answer:
The school banner can fit across the length of the concession stand
Step-by-step explanation:
The following information is missing:
The length if the sides: c is 50 feet long, b is 40 foot long, and a is 30-foot long.
The distance between the two red stars of the picture makes the hypotenuse of a right triangle, where two sides of length a (30 ft) are the legs. From Pythagorean theorem, diagonal of quare A is:
diagonal² = 30² + 30²
diagonal = √1800 = 42.43 ft
which is longer than the banner.
The school banner can fit across the length of the concession stand is 42.43 ft.
What is Diagonal of Square?The line stretching from one corner of the square or rectangle to the opposite corner through the center of the figure is known as the diagonal. Any square that has two diagonals are equal in length to each other.
Here, the length of the sides: c is 50 feet long, b is 40 foot long, and a is 30-foot long.
The distance between the two red stars of the picture makes the hypotenuse of a right triangle, where two sides of length a (30 ft) are the legs.
From Pythagorean theorem, diagonal of square A is:
diagonal² = 30² + 30² = 1800
diagonal = [tex]\sqrt{1800}[/tex] = 42.43 ft
which is longer than the banner.
Thus, the school banner can fit across the length of the concession stand is 42.43 ft.
