What is a radical expression?Any expression that contains the radical () sign is referred to as a radical expression in mathematics. This symbol, which is frequently used to calculate the square root of a number, is frequently called the "square root" symbol by mistake. But it can also refer to a cube root, a fourth root, or something higher.
The 'V'-shaped portion of the radical sign will have a superscript number when it is used to represent any root other than a square root. For instance, the expression 3(8) denotes the cube root of 8. If there is no superscript number, the square root is required by the radical expression.

On a certain hot summer's day, 391 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $752.75. How many children and how many adults swam at the public pool that day?
Number of adults = 264
Number of children= 127
Step-by-step explanation:
Let the number of adults be......x
Let the number of children be.....y
The total number of people that used the public swimming pool is given as 391. This means
x+y=391
The total cost per the receipt is : $752.75
This means, 2.25 x+ 1.25 y = 752.75
The two equations are;
x+y=391 ...........(i)
2.25 x+ 1.25 y = 752.75...........(ii)
Making the x variable equal to eliminate x
2.25x + 2.25 y = 879.75
2.25x + 1.25 y = 752.75
Apply subtraction as
1.00 y = 127.00
y=127
Use the value of y in equation (i)
x+y=391
x+127=391
x=391-127=264
Number of adults = 264
Number of children= 127

if you add Natalie's age and Fred's age, the result is 45. if you add Fred's age to 3 times Natalie's age, the result is 73. Find how old Fred and Natalie are.
Answer:
Fred is 31 years old and Natalie is 14 years old.
Step-by-step explanation:
Given:
If you add Natalie's age and Fred's age, the result is 45.
If you add Fred's age to 3 times Natalie's age, the result is 73.
Now, to find the age of Fred and Natalie.
Let the age of Fred be [tex]x.[/tex]
And the age of Natalie be [tex]y.[/tex]
As, given If you add Natalie's age and Fred's age, the result is 45.

Kiyo and Steven are tiling the floors in an
office building. Kiyo tiled of the floor in
one office, and Steven tiled of the floor
in another office.
Write to explain how to use a benchmark
fraction to determine who tiled a greater
portion of a floor.
The complete question is given below.
Question:
Kiyo and Steven are tiling the floors in an office building. Kiyo tiled [tex]\frac{3}{6}[/tex] of the floor in one office, and Steven tiled [tex]\frac{5}{12}[/tex] of the floor in another office. Write to explain how to use a benchmark fraction to determine who tiled a greater portion of a floor.
Answer:
Kiyo tiled a greater portion of a floor
Solution:
Kiyo tiled in one office = [tex]\frac{3}{6}[/tex]
Steven tiled in another office = [tex]\frac{5}{12}[/tex]
Bench mark fraction means comparing fractions with common fraction or number. Most probably we use [tex]\frac{1}{2}[/tex] as the common fraction.
Compare [tex]\frac{3}{6}[/tex] and [tex]\frac{5}{12}[/tex] using [tex]\frac{1}{2}[/tex]:
[tex]\frac{3}{6}[/tex] is equal to the fraction [tex]\frac{1}{2}[/tex].
[tex]$\frac{3}{6}=\frac{1}{2}[/tex]
[tex]$\frac{5}{12}<\frac{1}{2}[/tex]
[tex]$\Rightarrow\frac{5}{12}<\frac{3}{6}[/tex]
Steven tiled the floor < Kiyo tiled the floor.
Hence Kiyo tiled a greater portion of a floor.
Kiyo tiled a greater portion of the floor.
To determine who tiled a greater portion of the floor, we can use a benchmark fraction. A common benchmark fraction is 1/2. Let's compare each person's portion to this benchmark:
Kiyo tiled 3/6 of the floor. Simplifying this fraction, we get 1/2.
Steven tiled 5/12 of the floor. To compare this to 1/2, we check if 5/12 is more than or less than 6/12 (which is 1/2).
Since 5/12 is less than 6/12, Steven tiled less than half, and Kiyo tiled exactly half.
Therefore, Kiyo tiled a greater portion of the floor.
Complete question: Kiyo and Steven are tiling the floors in an office building. Kiyo tiled 3/6 of the floor in one office, and Steven tiled 5/12 of the floor in another office. Write to explain how to use a benchmark fraction to determine who tiled a greater portion of a floor. You can compare hese fractions because the floors in each office are the same size. ∩ C

Dogs are inbred for such desirable characteristics as blue eye color; but an unfortunate by-product of such inbreeding can be the emergence of characteristics such as deafness. A 1992 study of Dalmatians (by Strain and others, as reported in The Dalmatians Dilemma) found the following:
(i) 31% of all Dalmatians have blue eyes.
(ii) 38% of all Dalmatians are deaf.
(iii) 42% of blue-eyed Dalmatians are deaf.
What is the probability that a randomly chosen Dalmatian is blue-eyed and deaf?
Answer:
0.1302 or 13.02%
Step-by-step explanation:
So we know that 31% of the Dalmatians are blue eyed so that is 0.31. We also know that 42% of blue eyed Dalmatians are deaf so that is 0.42.
To find the probability of a blue eyed deaf Dalmatian we need 42% of 31%, so we need to do:
0.42 × 0.31 = 0.1302 or 13.02%

As a salesperson you are paid $70 per week plus $6 per sale. This week you want your pay to be at least $150. Write an inequality to represent the number of sales you need to make to achieve your goal. Then solve the inequality algebraically, showing all work on your paper.
The inequality is:
[tex]70+6x\geq 150[/tex]
You must do more than 14 sales to get at least $ 150
Solution:
Given that,
As a salesperson you are paid $70 per week plus $6 per sale
Let "x" be the number of sales
This week you want your pay to be at least $150
We have to frame a inequality to represent the number of sales you need to make to achieve your goal
This week he must earn at least $ 150
Thus, he can spend $ 150 or more then 150 also
So we have to use "greater than or equal to" symbol
From given,
[tex]70 + 6(\text{number of sales})\geq 150[/tex]
[tex]70+6x\geq 150[/tex]
Thus the inequality is found
Solve the inequality
[tex]70+6x\geq 150\\\\Subtract\ 70\ from\ both\ sides\\\\6x\geq 150-70\\\\6x\geq 80\\\\Divide\ both\ sides\ by\ 6\\\\x\geq 13.3\\\\Thus\ approximately\ we\ get\\\\x\geq 14[/tex]
So he must do more than 14 sales to get at least $ 150

8 times what equals close to 289
The step-by-step solution shows that the number close to 289 when multiplied by 8 is approximately 36.125. Multiplying 36 by 8 gives 288, which is close to 289.
To find the number which, when multiplied by 8, gives a value close to 289, we can set up the equation:
8x ≈ 289
To solve for x, we divide 289 by 8:
x = 289 ÷ 8Performing the division:
x ≈ 36.125So, 8 times approximately 36.125 equals close to 289. Therefore, the nearest whole number would be 36, since 8 * 36 = 288, which is close to 289.
The step-by-step solution shows that the number close to 289 when multiplied by 8 is approximately 36.125. Multiplying 36 by 8 gives 288, which is close to 289.
