Answer: [tex]\dfrac{33}{40}\ gm[/tex]
Step-by-step explanation:
Given
Neville place three weights in the sequence
[tex]\dfrac{1}{2}\ gm,\dfrac{1}{5}\ gm,\dfrac{1}{8}\ gm[/tex]
The total weight of the three weights is
[tex]\Rightarrow \dfrac{1}{2}+\dfrac{1}{5}+\dfrac{1}{8}=\dfrac{20+8+5}{40}\\\\\Rightarrow \dfrac{33}{40}\ gm[/tex]
Thus, herbs weigh [tex]\frac{33}{40}\ gm[/tex]
Which value from the set { 1/2 , 2/3 , 4/3 , 5/2 } is a value of x that will make the equation 3/4 ÷ x = 9/8 true?
Answer:
2/3
Step-by-step explanation:
To find out what x is in this case, divide 3/4 by 9/8.
3/4 / 9/8
Dividing by a fraction is the same as multiplying it's inverse.
3/4 * 8/9
Cross cancellation (3 & 9 (GCF: 3); 4 & 8 (GCF: 4)
1/1 * 2/3
We can remove the 1/1.
2/3
2/3 is the value of x that will make 3/4 ÷ x = 9/8 true.

Answer:
I) 616
II) 4.53
Step-by-step explanation:
For the first one, just plug in 7 as R.
A = 4 x (22/7) x 7^2
A = 12.57142857 x 49
A = 616
For the second, one, put 452 4/7 as A.
452 4/7 also is 258.285
258.285 = 4 x (22/7) x r^2
258.285 = 12.57142857 x r^2
Divide both sides by 12.57142857
20.55372408 = r^2
Square root 20.55372408 for R.
4.533621519 = R
OR
4.53 = R

[tex]\sqrt(12-8x)=x-3[/tex]
Answer:
x = -3 and x = 1
Step-by-step explanation:
first, square each side
12 - 8x = x² - 6x + 9
x² + 2x - 3 = 0
(x - 1)(x + 3) = 0
x = -3
x = 1

The first term of a geometric sequence is 4, and the common ratio is 5. What is the 5th term of the sequence?
a.2,500
b.12,500
c.1,024
d.500
Answer:
A) 2,500
Step-by-step explanation:
Soo.....
A1 = 4
A2 = 4*5 = 20
A3 = 20*5 = 100
A4 = 100*5 = 500
A5 = 500*5 = 2,500

y = 3/4x -2
Write the equation for the word problem and solve. You bought a magazine for $5 and four erasers. You spent a total of $25. How much did each eraser cost?
Answer: each eraser cost 5 dollors
Step-by-step explanation: Simplifying
25 = 5 + 4e
Solving
25 = 5 + 4e
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-4e' to each side of the equation.
25 + -4e = 5 + 4e + -4e
Combine like terms: 4e + -4e = 0
25 + -4e = 5 + 0
25 + -4e = 5
Add '-25' to each side of the equation.
25 + -25 + -4e = 5 + -25
Combine like terms: 25 + -25 = 0
0 + -4e = 5 + -25
-4e = 5 + -25
Combine like terms: 5 + -25 = -20
-4e = -20
Divide each side by '-4'.
e = 5
Simplifying
e = 5

Find the area of the larger sector.
Round to the nearest tenth.
Answer:
399.6 square miles
Step-by-step explanation:
The Area of a sector =
x/360° × πr²
r = 13.4 miles
x = 255°
Hence,
255°/360° × π × 13.4²
= 399.5739336 square miles
Approximately = 399.6 square miles
Answer:
399.6
Step-by-step explanation:

Question 7 of 12 Solve: 3x- 8 = 6(1 - 2x) + 16 O A. x = 2 O B. x = 5 O C. x= -2 O D. There are infinitely many solutions.
Answer:
A. x =2
Step-by-step explanation: Rearrange terms 3x - 8 = 6 ( 1 - 2x ) + 16 ---> 3x - 8 = 6 ( -2x + 1 ) +16
Distribute
Add the numbers
Add 8 to both sides of the equation
Simplify
Add 12x to both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify -------> x=2
Find the equation of a parabola with focus F(-3, 9) and directrix x = -13.
Answer:
y² = 38x + 79
Step-by-step explanation:
Since directrix is the line x = -13, then it means x + 13 = 0
Focus is F(-3, 9).
Let A(x, y) be any point inside the plane having the focus and directrix.
Let MA be the perpendicular distance from A to the directrix and it means that A lies on parabola provided FA = MA.
Thus;
√[(x - (-3))² + (y - 9)²] = (x + 13)
Squaring both sides gives;
(x + 3)² + (y - 9)² = (x + 13)²
>> (x² + 6x + 9) + (y² - 18x + 81) = x² + 26x + 169
>> 6x + 9 + y² - 18x + 81 = 26x + 169
>> y² = 26x + 12x + 169 - 90
>> y² = 38x + 79

The amount of time Mary spends on the phone each month can be thought of as a random variable that is approximately normally distributed. Mary spends an average of 40 hours on her phone with a standard deviation of 4 hours. Find the probability that Mary spends between 30 and 40 hours on the phone.
Answer:
0.4938
Step-by-step explanation:
Given that:
Mean, m = 40
Standard deviation, s = 4
Probability of spending between 30and 40 hours on phone :
Zscore = (x - mean) / standard deviation
P(Z = 40) - P(Z= 30)
((40 - 40) / 4) - ((30-40) / 4)
(0/ 4) - (-10/ 4)
P(Z < 0) - P(Z <-2.5)
P(Z^ 0).=0.5 ; P(Z < - 2.5) = 0.0062097
0.5 - 0.0062097
P = 0.4938
It was the day before the big U.S. History test. It was an open-note exam, so if students took good notes, they would probably get a good grade on it. The problem for Helga was that she waited until the last minute to review her notes—and they were terrible. In a panic, she called her best friend, Tracy, and asked her to make a copy of the notes she took so Helga could use the copy to take the test. Tracy always took detailed notes, and Helga knew she would get a good grade if she used the copy of Tracy’s notes. Why is this most likely a dangerous situation for both Helga and Tracy? They would put their education at risk. They would break their parents’ rules. They would put their friendship at risk. They would break the school laws.
Answer:
Step-by-step explanation:
they would break the honor code of only using your own notes. Both could get a zero on the test. But.. this brings up the idea that the grade is worth anything in the first place.
