Step-by-step explanation:
Daniela has a container full of marbles. She gives away some of her marbles every day for five days. Each day, she has 1/4 the number of marbles she had a previous day. What fraction of the original number of marbles does Daniela have left after five days?
Given:
Daniela gives away some of her marbles every day for five days.
Each day, she has [tex]\dfrac{1}{4}[/tex] the number of marbles she had a previous day.
To find:
The fraction of the original number of marbles Daniela have left after five days.
Solution:
Let the origin number of marble be x.
Number of marbles after one day = [tex]\dfrac{1}{4}x[/tex]
Number of marbles after two days = [tex]\dfrac{1}{4}(\dfrac{1}{4}x)[/tex]
= [tex](\dfrac{1}{4})^2x[/tex]
Similarly,
Number of marbles after three days = [tex](\dfrac{1}{4})^3x[/tex]
Number of marbles after four days = [tex](\dfrac{1}{4})^4x[/tex]
Number of marbles after five days = [tex](\dfrac{1}{4})^5x[/tex]
= [tex]\dfrac{1}{1024}x[/tex]
Since, [tex]\dfrac{1}{1024}[/tex] is multiplied with x, therefore, the number of marbles Daniela have left after five days is [tex]\dfrac{1}{1024}[/tex] part of original number of marbles.
Which puts the equation 2x + y = 5 into slope-intercept form?
Answer:
y= -2x+ 5
Step-by-step explanation:
plug in y=mx+b
The equation 2x + y = 5 written in the slope-intercept form is y = -2x + 5, where the slope is -2 and the intercept is 5.
An equation in the slope-intercept form is written as y = mx + c.
The given equation is 2x + y = 5.
To write the given equation in slope-intercept form, subtract both sides of the equation with 2x,
(2x + y) - 2x = 5 - 2x
2x + y - 2x = 5 - 2x
y = 5 - 2x
Rearrange the terms
y = -2x + 5
Here, -2 is the slope and 5 is the intercept.
Thus, the slope-intercept form of the equation 2x + y = 5 is y = -2x + 5.

A wildlife preserve features a crocodile with a documented age of 24 years, believed to be one of the oldest crocodiles in captivity. The lifespans of crocodiles have an approximately Normal distribution, with a mean of 18 years and a standard deviation of 2.6 years. What proportion of crocodiles have lifespans of at least 24 years? Find the z-table here. O 0.0104 O 0.3336 O 0.4896 O 0.6664
Answer:
0.0104
Step-by-step explanation:
Given that, the lifespans of crocodiles have an approximately Normal distribution, with a mean of 18 years and a standard deviation of 2.6 years.
So, mean, [tex]\mu=18[/tex]
and standard deviation, [tex]\sigma=2.6[/tex]
The z-score, for any arbitrary life span of x year, is given by
[tex]z=\frac{x-\mu}{\sigma}[/tex]
By using the given values, we have
[tex]z=\frac{x-18}{2.6} \cdots(i)[/tex]
The z-score for x=24, by using equation (i), is
[tex]z=\frac{24-18}{2.6}=\frac{6}{2.6}=2.31[/tex]
From the table, the area to the left side of z=2.31 =0.98956
But, the proportion of crocodiles have lifespans of at least 24 years
= Area to the right side of the z=2.31
=1- (Area to the left side of the z=2.31)
=1-0.98956
=0.01044
So, the proportion of crocodiles that have lifespans of at least 24 years is 0.0104.
Hence, option (a) is correct.

Step-by-step explanation:
Unit price is measured by dividing the price by the amount of an item, so 3.72/12 = 0.31
Answer: The answer is C
Step-by-step explanation:
Given the speeds of each runner below, determine who runs the fastest. \text{Tony runs 12 feet per second.} Tony runs 12 feet per second. \text{Katie runs 450 feet in 30 seconds.} Katie runs 450 feet in 30 seconds. \text{Frank runs 1 mile in 577 seconds.} Frank runs 1 mile in 577 seconds. \text{Adam runs 880 feet in 1 minute.} Adam runs 880 feet in 1 minute.
Answer:
Katie runs fastest
Step-by-step explanation:
For us to know the person who runs fastest, we need to calculate their speed in feet per seconds (ft/s)
For Tony; his speed is 12ft/s
For Katie;
Katie runs 450 feet in 30seconds;
450 feet = 30 secs
x = 1 sec
Cross multiply
30x = 450
x = 450/30
x = 15ft
Hence Katie runs 15ft/s
For Frank;
Frank ran 1 mile per 577secs
1 mile = 5280feeet
This mean that he ran 5280feet in 577 secs
5280feet = 577secs
y = 1 secs
cross multiply;
577y = 5280
y = 5280/577
y = 9.15ft/s
Hence Frank ran 9.15ft/s
For Adam;'
If Adam ran 880 ft in 1 minutes, this means he ran 880ft in 60secs
880 ft = 60secs
z = 1sec
Cross multiply
60z = 880
z = 880/60
z = 14.67ft/s
Hence Adam ran 14.67ft/s
From the value of their speed, we can see that Katie runs fastest with a speed of 15ft/s

2 to the power of 46 is how many times as many as 2 to the power of 42
Answer:
2⁴⁶ is 2⁻⁴ times as many as 2⁴²
Step-by-step explanation:
Given;
2 to the power of 46 = 2⁴⁶
2 to the power of 42 = 2⁴²
Let the number of times = y
2⁴⁶y = 2⁴²
divide both side of the equation by 2⁴⁶
[tex]\frac{2^{46}y}{2^{46}} = \frac{2^{42}}{2^{46}} \\\\y = 2^{42-46}\\\\y = 2^{-4}[/tex]
Therefore, 2 to the power of 46 is 2 to the power -4 times as many as 2 to the power of 42. (i.e 2⁴⁶ is 2⁻⁴ times as many as 2⁴²)

Forensic scientists can determine the approximate height that a person was by measuring the length of the femur (thigh bone). They use a formula to calculate the person’s height, based on the person’s race and gender. The formula for a Caucasian female is given by: height = 2.47f + 54.13, where f is the length of the femur in centimeters.
To the nearest centimeter, how many centimeters long is the femur of a female who is 168 centimeters tall?
46 centimeters
90 centimeters
14 centimeters
469 centimeters
Answer:
46 centimeters.
Step-by-step explanation:
First you need to plug in the numbers you have.
Your equation now is:
168 = 2.47f + 54.13.
You could use the process of elimination, or you could solve it algebraically.
168 = 2.47f + 54.13.
What you want to do is subtract 54.13 from both sides.
113.87 = 2.47f.
Now divide 2.47 from both sides.
46
The length of the femur of a female with a height of 168 cm is; Option A: 45 centimeters.
We are given the formula for Caucasian female's height as;
H = 2.47f + 54.13
Where;
f is the femur length in cm.
H is height in cm
Thus, if a females height is 168 cm, then;
168 = 2.47f + 54.13
Using subtraction property of equality by subtracting 54.13 from both sides gives;
168 - 54.13 = 2.47f
113.87 = 2.47f
Using division property of equality, divide both sides by 2.47 to get;
113.87/2.47 = f
f ≈ 46 cm

y − 6 = −(x + 4)
====================================================
Work Shown:
y - 6 = -(x + 4)
y - 6 = -x - 4
y = -x - 4 + 6 ..... adding 6 to both sides
y = -x + 2
y + x = 2 .... adding x to both sides
x + y = 2
The equation is in standard form Ax+By = C, with A = 1, B = 1, and C = 2.
