Answer:
True, these measures do form a right triangle.
Step-by-step explanation:
Pythagorean Theorem: a^2 + b^2 = c^2
(6)^2 + (8)^2 = (10)^2
36 + 64 = 100
100 = 100
So, its true these measurements do form a right triangle.

Hector spent $41.75 for 2 DVDs that cost the same amount. The sales tax on his purchase was $3.15. Hector also used a coupon for $1.00 off his purchase. How much did each DVD cost?
Given:
Amount spent on 2 DVDs = $41.75
Sales tax = $3.15
Coupon = $1.00 off
To find:
The cost of each DVD.
Solution:
Let x be the cost of each DVD.
Then, cost of two DVDs = 2x
Amount spent of 2 DVDs = Cost of 2 DVDs + Sales tax - Coupon discount
[tex]41.75=2x+3.15-1.00[/tex]
[tex]41.75=2x+2.15[/tex]
[tex]41.75-2.15=2x[/tex]
[tex]39.6=2x[/tex]
Divide both sides by 2.
[tex]\dfrac{39.6}{2}=x[/tex]
[tex]19.8=x[/tex]
Therefore, the cost of each DVD is $19.8.

The block company is to paint 257 cylindrical blocks like this one which has a radius of 1.5cm and a height of 4cm. If the paint costs $ 0.52 per cm2, what will be the total price the company will have to pay?
Answer:
Let us consider the equation of a partial disk Hence A= pi × r^2/ 2Answer:
[tex]\$3463.70[/tex]
Step-by-step explanation:
Start by finding the total surface area of one block. The surface area of this half-cylinder is:
[tex]2\cdot\frac{1}{2}r^2\pi+\frac{1}{2}\cdot2r\pi\cdot h[/tex]
Since both radius and height are given, we can solve the equation:
[tex](1.5)^2\cdot \pi +1.5 \cdot \pi \cdot 4 \approx \fbox{$25.9\:\mathrm{cm^2}$}[/tex].
Since the company is painting 257 of these, the total surface area of all the blocks will be:
[tex]({(1.5)^2\cdot \pi + 1.5 \cdot \pi \cdot 4)\cdot 257\approx \fbox{$6660\:\mathrm{cm^2}$}[/tex].
Each square centimeter costs $0.52, so the total cost the company will have to pay is:
[tex]({(1.5)^2\cdot \pi + 1.5 \cdot \pi \cdot 4)\cdot 257\cdot 0.52\approx \fbox{$\$3463.70$}[/tex].

55°
x + 74
54°
Answer:
x = -3
Step-by-step explanation:
55 + 54 = 109
109 + 74 = 183
Triangles = 180 degrees
So, 74 - 3 = 71
And 55+54+71 = 180

The table and the graph each show a different relationship between the same two variables, x and y:
How much more would the value of y be in the table, than its value on the graph, when x = 11?
Group of answer choices
110
170
385
495
Answer:
[tex]\displaystyle 385[/tex]
Step-by-step explanation:
The rate of change [slope] of the graph is 35, and for every two blocks you horisontally move represents seventy blocks vertical-wise, therefore an ELEVENTH block would require you to split 70 in half, giving you 35, then add this to 350 to get 385.
I am joyous to assist you at any time.
Answer:
The answer is Option B.) 385
Step-by-step explanation:
The pace of progress of the chart is 35, and for each two squares you horizontally move addresses seventy squares vertical-wise, thusly an 11 square would expect you to part 70 fifty-fifty, giving you 35, then, at that point, add this to 350 to get 385 as a result.
How do you find the slope when you are only given an equation or a table?
Answer:
All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.
Step-by-step explanation:
Answer:
Step-by-step explanation:
slope in an equation is the number before the x
in a table it is y2-y1/x2-x1
Point (21,28) is dilated by a scale factor of (-1/7) with a center of dilation on the origin. What are the new coordinates
Step-by-step explanation:
Original x-value = 21
New x-value = 21 * (-1/7) = -3.
Original y-value = 28
New y-value = 28 * (-1/7) = -4.
Hence the coordinates of the new point is (-3,-4).
Answer:
Original value of x-axis =21
New value of x-axis = 21×(-1/7) = -3
Original value of y-axis =28
New value of y-axis = 28×(-1/7) = -4
Hence, the new coordinate is (-3,-4).

Solve using the Quadratic Formula for 2x2 + 5x – 3 = 0
x = -5, 7
b. X = -12,2
X = -3,42
Step-by-step explanation:
[tex] \tt{2 {x}^{2} + 5x - 3 = 0}[/tex]
⇢ [tex] \sf{2 {x}^{2} + 5x + ( - 3) = 0}[/tex]
Here , a = 2 , b = 5 & c = -3 {a is the coefficient of x² , b is the coefficient of x and c is the constant term }
Now ,
[tex] \tt{x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} }[/tex]
⇢ [tex] \tt{x = \frac{ - 5± \sqrt{ {5}^{2} - 4 \times 2 \times ( - 3) } }{2 \times 2} }[/tex]
⇢ [tex] \sf{ x= \frac{ - 5±7}{4} }[/tex]
Taking positive ( + ) sign :

Answer: 73
Step-by-step explanation:
so i took what the angle was for the 107 and subtracted it from 180 because that's always how I did it i'm not positive if its correct but I think that's how you do it since there all the same angles on the bottom so M and Q match and the two top angles match so I think it would end up being 73 sorry if this isn't to much help.

12. Which explains whether the relation shown is a function?
A) The relation is a function since it is continuous.
B) The relation is not a function since it is not symmetrical
C) The relation is a function since it passes the vertical line test
D) The relation is not a function since it does not pass the horizontal line test.
Answer:
C
Step-by-step explanation:
the vertical line test is when you check to see if a point of the graph is passed twice. in this case it does pass the vertical line test. therefore, it is a function.

The volunteers at a high school football team's concession stand are trying to decide on the price of the hot dogs they are selling. When they charge $2 for a hot dog, they sell an average of 70 hot dogs per game. With every $1 increase in the price, the number of hot dogs sold per game decreases by 8. The volunteers can calculate the revenue earned from selling the hot dogs at each game using the expression -8x2 + 54x + 140, where x is the number of $1 increases in price.
Answer:
The constant term in the polynomial is 140 and it represents the revenue when the price is not increased.
Step-by-step explanation:
To find: What is the constant term in the polynomial expression, and what does it represent?
The given expression is [tex]-8x^2 + 54x + 140[/tex].
To find the constant term we can simply put x=0 in the given equation where x represents the number of $1 increase in price.
=[tex]-8(0)^2 + 54(0) + 140[/tex]
=[tex]140[/tex]
The constant term is 140 and it represents the revenue when the cost of a hot dog is $2.
Hence, the constant term in the polynomial is 140 and it represents the revenue when the price is not increased.
