Answer:
- 8x² + 14x - 6
Step-by-step explanation:
Given
(- 8x² + 10x + 4) - (- 4x + 10)
Distribute the parenthesis, noting to distribute the second one by - 1
= - 8x² + 10x + 4 + 4x - 10 ← collect like terms
= - 8x² + 14x - 6

Answer:
14.4222051019 or 14.42
Step-by-step explanation:
a^2 + b^2 = c^2
x^2 + 9^2 = 17^2
x^2 + 81 = 289
x^2 = 289 - 81
x^2 = 208
x = 14.4222051019 or 14.42

Step-by-step explanation:
Hello There!
x = # of cars and y = # of vans
the total amount of vehicles is 12 so
x + y = 12
each car can hold 4 students and each van can carry 12 students
there are a total amount of 72 students
so 4x + 12y = 72
so from the given information we can conclude that the answer is C

A sandwich store charges $20 to have 3 turkey subs delivered and $26 to have 4 delivered. The total includes the cost of each sub, plus the delivery fee.
Answer:
cost of each sub = $6, delivery fee = $2
Step-by-step explanation:
Let $x be the cost of each sub and $c be the delivery fee
3x + c = 20
4x + c = 26
x = 6, c = 2

A custom-illustrated sign or banner can be commissioned for a cost of $20 for the material and $12.50 per square foot for the artwork. The equation that represents this cost is given by y = 12.50x + 20, where y is the cost and x is the number of square feet in the sign.
Graph this equation for values of x from 0 to 20.
The point (5, 82.5) is on the graph. Select a sentence that describes the meaning of this ordered pair.
A. It costs $5 for a custom sign 82.5 ft2 in area.
B. It costs $12.50 for a custom sign 20 ft2 in area.
C. It costs $20 for a custom sign 12.50 ft2 in area.
D. It costs $82.50 for a custom sign 5 ft2 in area.
E. It costs $270 for a custom sign 20 ft2 in area.
Answer:
D
Step-by-step explanation:
12.50 x 5 = 62.5
62.5 + 20 = 82.5

If you need to construct a dog run for your dog and the total perimeter needs to be 40 feet, and you only have enough room to make it 5 feet wide, how long can you make the dog run?
Answer:15 ft
Step-by-step explanation:
Given
The total perimeter needed is [tex]40\ ft[/tex]
The available width of the room is [tex]w=5\ ft[/tex]
Suppose l is the length of the room
So, the perimeter of a rectangle-shaped room is [tex]2(l+w)[/tex]
Putting values
[tex]\Rightarrow 40=2(l+5)\\\Rightarrow l+5=20\\\Rightarrow l=15\ ft[/tex]

Element X decays radioactively with a half life of 8 minutes. If there are 480 grams of
Element X, how long, to the nearest tenth of a minute, would it take the element to
decay to 14 grams?
y=a(.5)
Answer:
40.8 minutes
Step-by-step explanation:
Element X decays radioactively with a half life of 8 minutes. If there are 480 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 14 grams?
The formula to find how long it would take which is the time elapsed is given as:
t = t½ × In(Nt/No)/-In2
t = ?
t½ = 8 minutes
Nt = Amount after the time of decay = 14 grams
No = Original Amount of substances = 480 grams
t = 8 × In(14/480)/-In2
t = 40.796285388407 minutes
Approximately to the nearest tenth = 40.8 minutes
Therefore, it would take the element X, 40.8 minutes to decay to 14 grams

If a designer sold 2,000 units of a dress with total sales of $190,000, what was the average price of the garment?
Answer:
$95
Step-by-step explanation:
We can divide 190,000 by 2,000, since we're assuming they all cost the same. This gets us to our answer, 95. Therefore, each garment cost $95 on average.

Answer:
10
Step-by-step explanation:
using the pythagorean theory the missing side would be [tex]c^{2}[/tex] bs its the hypotenuse so
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]8^{2} + 6^{2} = c^{2}[/tex]
[tex]64 + 36 = c^{2}[/tex]
[tex]100 = c^{2}[/tex]
and the square root of 100 is 10, which makes your equation
[tex]c = 10[/tex]

Mrs. Humble is filling bags with peanuts to give as gifts. Each bag will contain 1 and 3 over 4 pounds of peanuts. The peanuts cost $5.00 per pound. How much will the peanuts in one bag cost?Mrs. Humble is filling bags with peanuts to give as gifts. Each bag will contain 1\frac{3}{4} pounds of peanuts. The peanuts cost $5.00 per pound. How much will the peanuts in one bag cost?
Answer:
$8.75
Step-by-step explanation:
STEP TO TAKE TO DETERMINE THE ANSWER
Multiply 13/4 pounds by the cost of one pound of peanut. To do this, convert 13/4 to an improper fraction and then multiply it by $5
[tex]1\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]
[tex]\frac{7}{4}[/tex] × 5 = [tex]\frac{35}{4}[/tex] = [tex]8\frac{3}{4}[/tex] = $8.75
May someone help me with this. I have to use the Pythagorean theorem for this problem. May you show steps too?
Answer:
the missing side value is 6.7.
Step-by-step explanation:
so the Pythagorean theorem is a^2+b^2=c^2, but since we are missing the b slide the equation now is 7^2-2^2=b^2. now you may not understand why we are missing the b side. so in the Pythagorean theorem, the a and b slides dont really matter, as long as the c side is the hypotenuse, or the longest slide in a triangle. so 7squared is 49, 2 squared is 4, so 49-4= 45, but its 45squared because the equation is c^2-a^2=b^2 so now we know that 45 is b squared, we just have to square root 45, to get about 6.7.
