7 1/2 is equal to _____ in radical form?
Answer:
√ 7
.........................
7 1/2 in radical form is √15 / √2 x √15 / √2.
To convert the mixed number 7 1/2 to radical form, we need to rewrite it as an improper fraction and then simplify.
First, let's convert the mixed number to an improper fraction:
7 1/2 = (2 x 7 + 1)/2 = 15/2
Next, we can represent 15/2 in radical form by taking the square root of the numerator and the denominator separately:
√(15/2)² = √15 / √2 x √15 / √2
The square root of 15 cannot be simplified further, so we leave it as √15.
Therefore, 7 1/2 in radical form is √15 / √2 x √15 / √2.

A young sumo wrestler goes on a special diet to gain weight. The variable w models the wrestlers weight in km after the wrestler has been on a special diet for t months.
w=80+5.4t
How much weight does the wrestler gain every 2 months
Answer:
10.8kg
Step-by-step explanation:
Before he was on the diet he already weighed 80 kilograms, so it is not important to determining how much weight we gains in two months. Instead we need to focus on the 5.4t part of the equation. t represents the number of months so we need to substitute 2 for t and you get
5.4t

Answer:
x = √53
Use the pythagorean theorem to solve for x, which would be c in the equation a^2 + b^2 = c^2.
(a and b are the sides that meet up in a right triangle, c is the hypotenuse. In this case, you are solving for the hypotenuse.)
Step-by-step explanation:
1. Plug in the numbers in the pythagorean theorem.
2^2 + 7^2 = c^2 (remember, each variable is squared)
2. Simplify.
4 + 49 = 53
Since each variable in the pythagorean theorem is squared, the side value would be √53.

What type of equations could have extraneous solutions?
Answer:
id
Step-by-step explanation:
The square root equations could have extraneous solutions.
What is an extraneous solution?An extraneous solution is a “false” solution to an equation. An extraneous solution does not satisfy the original equation, even though we took seemingly valid steps while solving the equation.
When we solve an equation with containing a radical expression, we have to isolate the radical on one side from all other terms and then square both sides of the equation.
When we square a radical equation we sometimes get a solution to the squared equation that is not a solution to the original equation. Such an equation is called an extraneous solution.
Hence, the square root equations could have extraneous solutions.

Original price: $___
Discount: 55%
Sale price: $49.05
Item: Archery Set
Original price: $94.00
Discount: ___%
Sale price: $61.10
Answer:
Jersey: 85.75/100 X 80 = $68.60
Tennis Racket 55% = 49.05, 1%=0.89181818, 100% = 89.1818181 = $89.18
Archery = 94- 61.10 = 32.90, 32.90/94= 0.35
0.35 X 100 = 35%
Two sides of a triangle measure 17 inches and 9 inches. Which cannot be the length of the remaining side?
Answer: B. 26
Step-by-step explanation:
The options are:
A. 21
B. 26
C. 9
D. 15
Let the third side of the triangle be x.
Since the two sides of a triangle measure 17 inches and 9 inches, therefore we can form a triangle inequality with the figures given. This would be:
x + 9 > 17
x > 17 - 9
x > 8
Also,
x < 9 + 17
x < 26
Therefore, 8 < x < 26
Therefore, the answer is 26.

jasons cutting a 2 2/5 meter string into sections that are 3/4. how many sections can he cut
Answer:
3 1/5
Step-by-step explanation:
Okay, this is a standard division problem, so our equation is:
2 2/5 ÷ 3/4
but then we have to covert the mixed number to an improper fraction:
12/5 ÷ 3/4
do the cross thingy:
4/5 x 4/1 = 16/5 = 3 1/5
So Jason can cut 3 1/5 sections or 3 if you round

Answer:
Simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex] is [tex]\mathbf{\frac{1}{(x+3)(x+4)} }[/tex]
Option A is correct answer.
Step-by-step explanation:
We need to find simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex]
Solving the given expression:
[tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex]
First we find factors of [tex]x^2+x-6[/tex]
[tex]x^2+x-6 \\= x^2+3x-2x-6\\= x(x+3)-2(x+3)\\=(x-2)(x+3)[/tex]
So, factors of [tex]x^2+x-6[/tex] are [tex](x-2)(x+3)[/tex]
Now, fining the factors of [tex]x^2+5x+4[/tex]
[tex]x^2+5x+4\\=x^2+4x+x+4\\=x(x+4)+1(x+4)\\=(x+1)(x+4)[/tex]
So, factors of [tex]x^2+5x+4[/tex] are [tex](x+1)(x+4)\\[/tex]
Now the given expression will become:
[tex]\frac{x+1}{(x-2)(x+3)}\div \frac{(x+1)(x+4)}{x-2}[/tex]
Now, converting division sign into multiplication sign:
[tex]=\frac{x+1}{(x-2)(x+3)}\times \frac{x-2} {(x+1)(x+4)}\\Cancelling, \:common\:terms\\=\frac{1}{(x+3)(x+4)}[/tex]
So, simplified form of [tex]\frac{x+1}{x^2+x-6}\div \frac{x^2+5x+4}{x-2}[/tex] is [tex]\mathbf{\frac{1}{(x+3)(x+4)} }[/tex]

Jose has six pieces of cardboard to make a triangle frame for a diorama. The lengths are 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, and 7 inches. Which combination will form a triangle?
The possible combination of sides of triangles is
(2 + 3) >4(3 + 4)> 5(5+ 6)>7What is Property of Triangle?In a triangle, the third side must be greater than or equal to the sum of the other two sides. The length of a triangle's third side is always longer than the sum of any two of its sides.
Given sides are 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, and 7 inches.
We know that the third side of a triangle is greater than sum of other two sides.
So, (2 + 3) >4
