Lauren studies for 3 1/3 hours. She took a break every 2/3 hour. How many breaks did she take?
To solve the question, we have to divide the number if hours used in studying by the interval used in taking a break. This will be:
= 3 1/3 ÷ 2/3
= 10/3 / 2/3
= 10/3 × 3/2
= 5
She took a break 5 times

Given:
The expression is:
[tex]\dfrac{15m^2-3}{3m-1}[/tex]
To find:
The simplified value of the given expression.
Solution:
We have,
[tex]\dfrac{15m^2-3}{3m-1}[/tex]
On dividing, we get
[tex](3m-1)|\overline{15m^2+0m-3}|5m+\dfrac{5}{3}[/tex]
[tex]-(15m^2-5m)[/tex]
[tex]\overline{\quad \quad -5m-3}[/tex]
[tex]-(5m-\dfrac{5}{3})[/tex]
[tex]\overline{\quad \quad -\dfrac{4}{3}}[/tex]
Here, quotient is [tex]5m+\dfrac{5}{3}[/tex] and the remainder is [tex]-\dfrac{4}{3}[/tex].
Therefore, [tex]\dfrac{15m^2-3}{3m-1}=5m+\dfrac{5}{3}-\dfrac{4}{3(3m-1)}[/tex].
In the triangle above, the measure of A is 66°, and the measure of B is 68°. What is the measure of C?
Answer:
46°
Step-by-step explanation:
Given that :
Angle, A = 66°
Angle B = 68°
The sum of angles in a triangle is given by :
A + B + C = 180° (sum if angles una triangle)
66° + 68° + C = 180°
134° + C = 180°
C = 180° - 134°
C = 46°
Hence, angle C is 46°

Answer:
3(4+√2)
Step-by-step explanation:
Here we need to find the perimeter of the given figure. Here the given figure is made from a triangle and a square. The side lenght of the square is 3. We need to find the hypontenuse of the triangle in order to find Perimeter .
• Using Pythagoras Theorem :-
⇒ h² = p² + b²
⇒ h² = 3² + 3²
⇒ h² = 9 + 9
⇒ h² = 18
⇒ h = √[ 9 × 2 ]
⇒ h = 3√2 .
Therefore the perimeter will be ,
⇒ P = 3√2 + 3 + 3 + 3 + 3
⇒ P = 3√2 + 12
⇒ P = 3( 4 + √2)
Hence the perimeter of the figure is 3(4+√2) .A rectangle has a width of (4g) and a length of (28 - 3). The perimeter of the rectangle is 54 units. What is the
value of g?
Answer:
Step-by-step explanation:
sorry do not .know
To find the value of g, we need to use the formula for the perimeter of a rectangle, which is:
P = 2(l + w)
where P is the perimeter, l is the length, and w is the width.
We are given that the width is 4g and the length is 28 - 3 = 25, so we can substitute these values into the formula:
54 = 2(25 + 4g)
Next, we can simplify the equation by first distributing the 2:
54 = 50 + 8g
Then, we can isolate g on one side of the equation by subtracting 50 from both sides:
4 = 8g
Finally, we can solve for g by dividing both sides by 8:
g = 4/8
Simplifying this expression gives us:
g = 1/2
Therefore, the value of g is 1/2.

Dylan invested some money into his bank.
He agreed a simple interest rate of 3% per annum for a period of 2 years
At the end of the 2 years period the value of his investment increased by 72%
Work out the value Dylan initial investment was?
Answer:
the initial investment is $1,200
Step-by-step explanation:
The computation of the initial investment is shown below:
As we know that
Let us assume the investment be 100
So, the investment increased be 72
So,
Simple interest = Principal × rate of interest × time period
72 = Principal × 3% × 2 years
So, the principal is
= 72 ÷ 3% × 2
= $1,200
hence, the initial investment is $1,200

Solve. Suppose that 1,000 students took a math examination wherein the maximum score that they can obtain is 100. Their average score is 70 with a standard of the deviation of 5. How many of the students obtained a score from 70 to 95?
Answer:
prolly like 689
Step-by-step explanation:
As per the given data, approximately 499 of the 1,000 students obtained a score from 70 to 95.
What is z-score?A standardized score is an example of a z-score. A z-score is a measure of how far a data point is from the mean in a distribution.
To solve this problem, we need to calculate the number of students who obtained a score from 70 to 95.
First, we need to calculate the z-scores for these two scores using the formula:
z = (score - mean) / standard deviation
For a score of 70:
z = (70 - 70) / 5 = 0
For a score of 95:
z = (95 - 70) / 5 = 5
Next, we need to find the area under the standard normal distribution curve between these two z-scores using a standard normal distribution table or calculator.
The area between z = 0 and z = 5 is approximately 0.499, or 49.9%.
Finally, we can calculate the number of students who obtained a score from 70 to 95 by multiplying this proportion by the total number of students:
Number of students = proportion x total number of students
Number of students = 0.499 x 1000
Number of students ≈ 499
Therefore, approximately 499 of the 1,000 students obtained a score from 70 to 95.

2-2N=3N+17
help plz thank you
Answer:
-3 = N
Step-by-step explanation:
2-2N=3N+17
Add 2N to each side
2-2N+2N=3N+2N+17
2 = 5N +17
Subtract 17 from each side
2-17 = 5N+17-17
-15 = 5N
Divide each side by 5
-15/5 = 5N/5
-3 = N
Answer:
N= -3
Step-by-step explanation:
First, bring 3N on to the left side by subtracting 3N with 2N
2-2N-3N=17
Then, move 2 to the right side by subtracting 17 and 2: -2N-3N= 17-2
Solving the like terms gives us -5N= 15
N= 15/-5
N= -3
find hcf of x³y and x⁴y³
no a and d
Answer:
See solutions below
Step-by-step explanation:
a) Given the expressions
x³y and x⁴y³
Find their factors
x³y = (x * x * x * y)
x⁴y³ = (x * x * x * y) * x * y * y
GCF = x*x*x*y
GCF = x³y
The expressions in parenthesis is the GCF. Hence the GCF of x³y and x⁴y³ is x³y
b) For 48m⁶n⁵p⁴ and 20m⁴n⁵p⁶
48m⁶n⁵p⁴ =12 * (4 * m⁴ * n⁵ * p⁴) * m²
20m⁴n⁵p⁶ = 5 * (4 * m⁴ * n⁵ * p⁴) * p²
GCF is the expression common to both terms
GCF = 4 * m⁴ * n⁵ * p⁴
GCF = 4m⁴n⁵p⁴
