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.

Answer:
44/12
Step-by-step explanation:
When adding fractions, remember that both of the fractions need a common denominator. See below:
11/12 + 11/4 * (3) = 11/12 + 33/12 = 44/12
12 is a common denominator, so you need to multiply 11/4 (both top and bottom) by 3.

Answer:
x =1Step-by-step explanation:
Given the following DE = 4X-2
EF = 3x+2
FG 5x-3
GD = 2x+5
Since DE is parallel to GF, this means that the sides are equal hence;
4x - 2 = 5x - 3
4x - 5x = -3 + 2
-x = -1
x = 1
Hence the value of x is 1

I'm not really sure what you did but I might have an idea. You might have subtracted the -5 and the -2x, but you cannot do that because they are not like terms and by that I mean that you have to subtract the -x from the -2x. The same goes for the -5 and -3 you have to keep those two together and subtract them. When you do that you will get -3x - 8.

Answer:
Cross Multiply
Step-by-step explanation:
Cross multiplication can help answer these questions.
a. 3x-4/8=x+2/3
step 1- multiply 8 and (x+2), and 3 and (3x-4)
8x+16=9x+12
step 2- Subtract 8x on both sides
16=x+12
step 3- subtract 12 on both sides
4=x, or x=4
b. 3(2-r)/4=3+r/6
step 1- open parentheses
3(2-r)=6-3r
6-3r/4=3+r/6
step 2- cross multiply (put them into a equation without fractions by cross multiplying)
(6-3r) · 6= (3+r) ·4
step 3- multiply
36-18r=12+4r
step 4- solve
add 18r on both sides
36=12+22r
subtract 12 from both sides
24=22r
divide by 22 on both sides
24/22 or 12/11=r
r=12/11
c. 4p+3/8=p+2/4
step 1- cross multiply
(4p+3) · 4= (p+2)·8
step 2- open the parentheses
16p+12=8p+16
step 3- solve
subtract 12 on both sides
16p=8p+4
subtract 8p on both sides
8p=4
divide by 8 on both sides
p=4/8, or p=1/2
d. 2(a-7)/15=a+4/6
step 1- open parentheses
2(a-7) = 2a-14
2a-14/15=a+4/6
step 2- cross multiply
(2a-14) · 6 = (a+4) · 15
step 3- open parentheses
12a-84=15a+60
step 4- solve
subtract 60 on both sides
12a-144=15a
(the answer is -144 because a negative minus a negative such as -80-60=-144.
subtract 12a on both sides
-144=3a
divide by 3 on both sides
-48=a, or a=-48

The data is skewed left with no outlier.
The data is skewed right with an outlier.
The data is skewed right with no outlier.
Answer:
The data is skewed left with an outlier.
Explanation:
Skewness occurs when the entries of the data set are either distributed more to the left or more to the right on the number line. In this case, most of the entries lie to the right, so the data set is skewed left.
The area of a circle, in terms of π, is 50π m(squared)
Find the value of the radius.
Give your answer as a simplified surd.
Step-by-step explanation:
It will pie r squared is equal to area
/ take this sign as pie
/ ×r^2=50/
r^2=50/÷/
r^2=50
r =
[tex] { \sqrt{50} } [/tex]
=
[tex]5 \sqrt{2} [/tex]
The value of the radius of the given circle is 5√2, of which the area is 50π m².
The formula for the area of a circle is A = πr², where A represents the area and r represents the radius.
As per the question, given that the area is 50π m².
So, we can set up the equation as follows:
50π = πr²
To solve for r, we divide both sides of the equation by π:
50 = r²
Taking the square root of both sides, we get:
√50 = √(r²)
Simplifying the square root of 50 gives:
r = √50
r = √(25 x 2)
r = 5√2
Therefore, the value of the radius is 5√2.

Renting roller blades costs a flate fee of $5 plus an additional $2.50 per hour. Write a linear equation that models this.
Answer:
Linear equation : y = 2.50h + 5
Step-by-step explanation:
Given that:
Fee for renting roller blades = $5
Per hour charges = $2.50
Let,
h be the number of hours roller blades were rented
y be the total amount
Total amount = Per hour charges * Number of hours + Flat fee
y = 2.50h + 5
Hence,
Linear equation : y = 2.50h + 5

The volume of the cylinder with height 15 units and radius 11 units is 1815 units³
What is volume?Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.
'Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
Given that, a cylinder with height 15 units and radius 11 units we need to find the volume of the same,
So, the volume of the cylinder is = π × radius² × height
= π × 11² × 15
= 1815π
Hence, the volume of the cylinder is 1815 units³

A rectangular tank measures 20cm x 30cm x 40cm. You want to fill it by using a cubic container that is 20cm on each side to carry water from a faucet to the tank. How many trips will it take?
Answer:
4 trips
Step-by-step explanation:
Given that:
Dimension of rectangular tank :
(20cm * 30cm * 40cm)
Dimension of cubic container used to fill tank = 20cm per side
Volume of tank = (20 * 30 * 40) = 24400 cm³
Volume of cubic container = (20 * 20 * 20) = 8000 cm³
Number of trips it would take :
Volume of tank / volume of container
24400 cm³ / 8000 cm³
= 3.05
Hence, it will take 4 trips
