Answer:
B. 256Step-by-step explanation:
Given function:
v(h) = 2^(h/4)It can be rewritten as:
v(d) = 2^d, where d- number of divisionsIf number of divisions is 8, then:
v(8) = 2^8 = 256 virus cellsCorrect choice is B
Answer:
Solution given:
v(h)=[tex] {2}^{\frac{h}{4}}[/tex]
we can write it as
v(d)=[tex] {2}^{d} [/tex]
now
v(8)=[tex] {2}^{8} [/tex]=256 virus cells will she have after 8 divisions.
Brent runs around a football field ,14m long and 12m inside. How much metre does Brent need in two laps
Answer:
Distance cover by Brent in 2 Lap = 104 meter
Step-by-step explanation:
Given:
Length of football field = 14 m
Width of football field = 12 m
Find:
Distance cover by Brent in 2 Lap
Computation:
Distance cover by Brent in 2 Lap = 2 x Perimeter of rectangular field
Perimeter of rectangle = 2[l+b]
Perimeter of rectangular field = 2[14 + 12]
Perimeter of rectangular field = 2[26]
Perimeter of rectangular field = 52 m
Distance cover by Brent in 2 Lap = 2 x Perimeter of rectangular field
Distance cover by Brent in 2 Lap = 2 x 52
Distance cover by Brent in 2 Lap = 104 meter
6. Sara Just spent $44 to get her hair styled. She
wants to leave a 15% tip for her hairdresser. How
much should she leave for the tip?
Answer:
$6.60
Step-by-step explanation:
You'd take the total anf multiply it by your percent amount with the decimal moved two places to the left
44 * .15 = 6.60
Plzzzzzzzzzzz my marking period ends in 3 days, I’m crying plzzz help
No links please and thank you
Answer:
Step-by-step explanation:
(find the percent by multiplying the percentage, .45, by the total number of shoes = 18 shoes)
% = 45%
p = 18
w = 40
(i did 100/40 which equals to 2.5 then multiplied 2.5 by the numerator so the numerator and denominator would both be equivelant.)
18/40 = 45/100
(multiply the whole (40) by the decimal value (.45) which is equal to 18)
40 x .45 = 18
(answer)
If Ms. M has 40 pairs of shoes, 18 of those shoes are sneakers.

Answer:
X = 1
Step-by-step explanation:
You first divide each side by 3 leaving you with X+5 = 6. Then you take the 5 to the other side leaving you with X=6-5 as the 5 changes from positive to negative. So 6-5=1 so X=1

What is the area of this square with sides of 5x⁴y²?
Answer:
Area of given Square = 25x⁸y⁴
Step-by-step explanation:
Given:
Side of a square = 5x⁴y²
Find:
Area of given Square
Computation:
Area of Square = Side²
Area of Square = Side × Side
Area of given Square = [5x⁴y²]²
Area of given Square = [5x⁴y²] × [5x⁴y²]
Area of given Square = [5 × 5][x⁴ × x⁴][y² × y²]
Area of given Square = [25][x⁴⁺⁴][y²⁺²]
Area of given Square = [25][x⁸][y⁴]
Area of given Square = 25x⁸y⁴

solve for a
2a+3b=12-2(2b+a)
PLEASE SHOW WORK ILL MARK BRAINLIEST.
Answer:
a = 3 - (7/4)b
Step-by-step explanation:
Start by performing the indicated multiplication:
2a+3b=12-2(2b+a) => 2a+3b=12 - 4b - 2a
Next, combine like terms: 4a + 7b = 12
Isolate 4a by subtracting 7b from both sides:
4a = 12 - 7b
Finally, divide both sides by 4:
a = 3 - (7/4)b
3x+6=21 what is the value of x
Answer:
[tex]3x + 6 = 21 \\ 3x = 21 - 6 \\ 3x = 15 \\ x = \frac{15}{3} \\ x = 5[/tex]
Answer: x=5
Step-by-step explanation:
step 1:
put all the coefficients on one side and all the variables on the other, 3x=21-6
step 2: solve the sides, 3x=15
step 3: divide, 3x/3= 15/3
step 4: simplify: x=5

The times to pop a regular bag of microwave popcorn without burning it are Normally distributed with a mean time
of 140 seconds and a standard deviation of 20 seconds. The times to pop a mini bag of microwave popcorn
without burning it are Normally distributed with a mean time of 90 seconds and a standard deviation of 15
seconds. Suppose two independent random samples, 25 of each, are taken and the mean popping times are
calculated. Let R = the popping time of a randomly selected regular-sized bag and M = the popping time of a mini-
sized bag. Which of the following best describes the standard deviation of the sampling distribution of 5-7 ?
1 second
5 seconds
25 seconds
35 seconds
Answer:
3
Step-by-step explanation:
Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.
What is Central Limit Theorem:?The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean.
here, we have,
Given,
In the question:
The times to pop a regular bag of microwave popcorn without burning it are Normally distributed with a mean time of 140 seconds and a standard deviation of 20 seconds. The times to pop a mini bag of microwave popcorn without burning it are Normally distributed with a mean time of 90 seconds and a standard deviation of 15 seconds.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 140, standard deviation of 20, sample of 4:
By the Central Limit Theorem, the distribution is approximately normal.
Mean is the same, of 140.
n = 4 , σ = 20, thus:
s = σ /√n
= 20/√4
= 10
Thus, the correct answer is:
Approximately normal with mean of 140 seconds and standard deviation of 10 seconds.

These four numbers are plotted on a number line: -2/3, 5/8, -3/5, and -1/2. Which is the correct ordering on the number line from left to right?
A. -1/2, -3/5, 5/8, -2/3
B. -3/5, -2/3, -1/2, 5/8
C. -2/3, -3/5, -1/2, 5/8
D. -1/2, -3/5, -2/3, 5/8
Answer:
-2/3 ; - 3/5 ; - 1/2 ; 5/8
Step-by-step explanation:
Given that:
We could convert the numbers to decimal to obtain a better view of the values :
-2/3 = - 0.66666
5/8 = 0.625
-3/5 = - 0.6
-1 /2 = - 0.5
Negative values are always arranged first on left of a number line.
-0.66666 < - 0.6 < - 0.5 <0.625
Hence,
-2/3 ; - 3/5 ; - 1/2 ; 5/8

Triangle ABC has vertices A(1,4), B(-1,5), and C(1,-4). Triangle ABC is dilated and
B' is located at (-3,15). What is the y-coordinate of C'?
Answer:
-12
Step-by-step explanation:
The coordinates of B' are just 3 times the coordinates of B, so the multiplier in the dilation is 3.
C' is the point with coordinates 3 times the coordinates of C, making C'(3, -12).
The y-coordinate is -12.

Create a system of equations to represent the word problem. Then solve using the linear combination/elimination method. Show all your work. Adam's Printing Inc. has two types of printing presses: Model A and Model B. Model A can print 80 books per day and Model B can print 55 books per day. Altogether Adam has 9 printing presses. If he can print 670 books in a day, then how many of each press does he have?
Answer:
Solution given:
model A printers [a] prints=80books per day
model B printers [b] prints=55books per day
total no of printers =9
no of model A printers be x
and
no of model B printers be [9-x]
According to the question;
ax+(9-x)b=670 books
substituting value of a and b; we get
80x+(9-x)55=670
80x-55x+495=670
25x=670-495=175
x=[tex] \frac{175}{25} [/tex]=7
So;
no of model A printers =x=7
no of model B printers =9-x=9-7=2
