simplify square root of 3/8
please give steps!!
Answers
Step-by-step explanation:
Write the expression
[tex] \sqrt{ \frac{3}{8} } [/tex]
Let make the denominator a perfect square that is a multiple of 8. 16 is a multiple of 8 and a perfect square so
[tex] \sqrt{ \frac{3}{8} } = \sqrt{ \frac{6}{16} } [/tex]
Know that
[tex] \sqrt{ \frac{x}{y} } = \frac{ \sqrt{x} }{ \sqrt{y} } [/tex]
So
[tex] \sqrt{ \frac{6}{16} } = \frac{ \sqrt{6} }{4} [/tex]
The simplified form of the square root of 3/8 is (√6) / 4.
To simplify the square root of 3/8, we can simplify the numerator and denominator separately.
For the numerator, we take the square root of 3:
√3
For the denominator, we take the square root of 8:
√8
Now, let's simplify each of them:
√3 cannot be simplified further because 3 is a prime number.
√8 can be simplified by factoring out the perfect square:
√8 = √(4 × 2)
Since 4 is a perfect square (2² = 4), we can take it out of the square root:
√8 = 2√2
Now, let's put the simplified numerator and denominator together:
√3/8 = √3 / (2√2)
To rationalize the denominator, we multiply the expression by the conjugate of the denominator:
(√3 / (2√2)) × (√2 / √2) = (√3√2) / (2√2√2)
Simplifying the denominator:
(√3√2) / (2√4) = (√6) / (2 × 2)
Simplifying further:
(√6) / (2×2) = (√6) / 4
Therefore, the simplified form of the square root of 3/8 is (√6) / 4.

a. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal.
b. What will the value of each card be when they have equal value?
a. If x is the number of 30-day periods, then the equation can be used to find the number of 30-day periods until the values of the gift cards will be equal.
(Type an equation. Use integers or decimals for any numbers in the equation)
Answers
Answer:
a. 65 - 3 x = 55 - 2.5 x
ab. 20
b. 5
Step-by-step explanation:
The equations are y = 110 - 2.5x and y = 90 - 2x. Then the value of each card, when they have equal value, will be $10.
What is a linear equation?The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Let x be the number of days and y be the value of the card.
Tavon has a gift card for $110 that loses $2.50 for each 30-day period it is not used. He has another gift card for $90 that loses $2 for each 30-day period it is not used. Then the equations will be
y = 110 - 2.5x ...1
y = 90 - 2x ...2
From equations 1 and 2, we have
110 - 2.5x = 90 - 2x
20 = 0.5x
x = 40
And the value of y will be
y = 110 - 2.5(40)
y = 110 - 100
y = $10
The equations are y = 110 - 2.5x and y = 90 - 2x. Then the value of each card, when they have equal value, will be $10.

for the food described, find what percent of total calories is from fat. if necessary round to the nearest tenth of a percent
*calories: 120
* calories from fat: 45
Answers
37.5%
Explanation:
0.375
The percentage of 45 out of 120 is 38% thus 38% calories from fat.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
Given that,
Total calories = 120
Calories from fat = 45
Fraction of calories from fat = 45/120 = 0.38
Percentage of calories from fat out of total calories ⇒
(45/120) × 100 = 38%
Hence "The percentage of 45 out of 120 is 38% thus 38% calories from fat".

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. q^2+7q
Answers
The square to make a perfect square trinomial as a binomial squared is
(q + 7/2q)² - 49/4.
We have been given that the expression -
q² + 7q.
We have to complete the square to make a perfect square trinomial. Then, write the result as a binomial squared.
We know that a perfect square trinomial is in form .
a² + 2ab + b².
To convert our given expression into perfect square trinomial, we need to add and subtract (b/2)² from our given expression.
We can see that value of b is 7, so we need to add and subtract (7/2)² to our expression as:
To complete the square, we will add the square of the half of the coefficient of q to the equation
Coefficient of q = 7
Half of the coefficient = 7/2
Square of the result = (7/2)² = 49/4
Adding 49/4 to the equation will make it a perfect square to have
Upon comparing our expression with , we can see that ,
(a + b)² = a² + 2ab + b²
now we can get
q² + 7q + 49/4 - 49/4
(q + 7/2q)² - 49/4
Therefore, our perfect square would be (q + 7/2q)² - 49/4 .

Angle ABC = angle ABD + angle DBC
We are given that angle ABC = 122 and angle ABD = 71
So 122 = 71 + angle DBC
* Solve for angle DBC *
Subtract 71 from both sides
122 - 71 = 71 - 71 + angle DBC
51 = angle DBC
m∠DBC = 51°
Step-by-step explanation:
m∠ABC = 122°
m∠ABD = 71°
m∠DBC = m∠ABC - m∠ABD
m∠DBC = 51°

6. Find the sum of whole number divisible by 3 and lies between 100 and 200.
Answers
Answer:
4950
Step-by-step explanation:
first find the smallest multiple of 3 thats >100, 3*33=99, so 3*34=102 is the smallest multiple of 3 >100.
next find the greatest multiple of 3 <200, 3*66=198 which is the greatest multiple of 3<200
34-66+1=number of terms=33. then find the average of the terms: 102+198/2=150. 150*33=4950. the answer should be 4950
Answer:
Step-by-step explanation:
The first number in the sequence = 102
The last number = 198
The number of terms =
L = a1 + (n-1)*d
198 = 102 + (n- 1)*3 Subtract 102
198 - 102 = (n - 1)* 3
96 = (n - 1)*3 divide by 3
32 = n - 1 add 1
33 = n
Sum = (a1 + L ) * n/2
sum = (102+198)*33/2
sum = 300 * 33/2
sum = 150 * 33
sum = 4950

So based off that, you would subtract the 9 women from the 32 total students. That would result in 23 students that are men.
Now to find that percent, take the 23 men and divide it by the total students- 32. So 23/32. And that would be 0.71875. But rounded to the nearest tenth is 0.7.

A 5-foot wide
hallway requires
440.5 ft2 of carpet
to cover. How
long is the
hallway, in feet?
Answers
Answer:
length × width = area
440.5 = 5 × length
length = 440.5 / 5
length = 88.1
so haway is 88.1 foot long
the length of the hallway is 88.1 feet. To find the length of the hallway, we need to use the given information about the width of the hallway and the total area of the carpet required to cover it.
Given:
Width of the hallway = 5 feet
Area of carpet required = 440.5 ft^2
Let's denote the length of the hallway as "L" (in feet).
The area of a rectangle (such as the hallway) is given by the formula:
Area = Length * Width
In this case, the area is given as 440.5 ft^2, and the width is given as 5 feet. Now we can set up the equation:
440.5 = L * 5
To find the length (L), divide both sides by 5:
L = 440.5 / 5
L = 88.1
So, the length of the hallway is 88.1 feet.

Answer:
8. 16,648
9. 1,394
10. 3
11. 9,570
Step-by-step explanation:
8. Total means all together so you need to add all of the attendants together.
2118 + 3391 + 4785 + 6354 = 16,648
9. How many more signifies the need to use subtraction to get your answer so you need to subtract the number of attendants in 2011(3,391) from the number of attendants in 2012(4,785)
4,785 - 3,391 = 1,394
10. How many times more signifies the need to use division in order to get the answer since it is the opposite of multiplication. So, you need to divide the number of attendants in 2010(2,118) from the number of attendants in 2013(6,354)
6,354 / 2,118 = 3
11. Twice the attendance signifies the need to use multiplication to find your answer so you need to multiply the number of attendants in 2012(4,785) twice(2).
4,785 x 2 = 9,570
