Answer:
5 3/8
-
1 5/8
= 3 3/4
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
3.75=3.75/1
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10 to the power of 2 = 100
3.75/1×100/100=375/100
Find the Greatest Common Factor (GCF) of 375 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 25,
375 ÷ 25
_______ = 15/4
100 ÷ 25
Simplify the improper fraction,
=3 3/4
In conclusion,
3.75=3 3/4
4x+3(2x-1)-4x i need help
Answer:
x=0.5
Step-by-step explanation:
Simplifying
4x + -3(2x + -1) + -4x = 0
Reorder the terms:
4x + -3(-1 + 2x) + -4x = 0
4x + (-1 * -3 + 2x * -3) + -4x = 0
4x + (3 + -6x) + -4x = 0
Reorder the terms:
3 + 4x + -6x + -4x = 0
Combine like terms: 4x + -6x = -2x
3 + -2x + -4x = 0
Combine like terms: -2x + -4x = -6x
3 + -6x = 0
Solving
3 + -6x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -6x = 0 + -3
Combine like terms: 3 + -3 = 0
0 + -6x = 0 + -3
-6x = 0 + -3
Combine like terms: 0 + -3 = -3
-6x = -3
Divide each side by '-6'.
x = 0.5
Simplifying
x = 0.5

Rick and Lisa each have their own cookie jar Rick's cookie jar is 7/8 full and Lisa is 5/8. Fraction represents how much more of Rick's jar is full than Lisa?
Answer:
2/8 is the right answer your welcome
2/8 of a jar more full.
Tip: ALWAYS circle the numbers or key information to get the best results.
Watch what happens!
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Some key information in this problem is 7/8, and 5/8.
Since they asked us how much more and what fraction represents it, we should subtract 5/8 from 7/8 to find how much more full Rick's jar is than Lisa's.
7/8 - 5/8 = 2/8
So in summary, Rick's jar is 2/8 more full than Lisa's jar.

Step-by-step explanation:
A tech company bought a number of computers for its employees: 66 costing \$1600$1600 each, 44 costing \$1200$1200 each, and yy costing \$900$900 each, where yy is a positive odd integer. If the median price for all the computers purchased by the company was \$1200,$1200, what is the greatest possible value of yy
Answer:
5
Step-by-step explanation:
A tech company bought a number of computers for its employees: 6 costing $1600 each, 4 costing $1200 each, and y costing $900 each, where y is a positive odd integer. what is the greatest possible value of y
Solution:
The median of a group of numbers is the middle number when the group of numbers have been arranged either in ascending of descending other. The median of an even group of numbers is the average of the two most middle most numbers while the median of an odd group of numbers is the middle number.
Since there are 6 computers costing $1600, 4 computers costing $1200 each and y computers costing $900 each. Since y is odd, hence y + 6 + 4 would be odd and the median would be the middle number.
Given that the median price = $1200, this means that the middle of the group of numbers is $1200
900, 900, ..., 1200, 1200, 1200, 1200, 1600, 1600, 1600, 1600, 1600, 1600
Since y is odd, for the median price to be $1200, y has to be 3 or 5.
If y = 3:
900, 900, 900, 1200, 1200, 1200, 1200, 1600, 1600, 1600, 1600, 1600, 1600
median = $1200
If y = 5:
900, 900, 900, 900, 900, 1200, 1200, 1200, 1200, 1600, 1600, 1600, 1600, 1600, 1600
Median = $1200
Therefore the greatest possible value of y is 5
By knowing that the median must be $1,200, we will see that the greatest possible value of y is y = 9.
We know that the company bought:
6 computers costing $1,6004 computers costing $1,200y computers costing $900We know that y is a positive odd number.
We also know that the median is $1200, now we want to get the maximum value of y such that the median is $1200. (Remember that the median is the value of the middle element of the set).
Then we will have the distribution:
{ y elements, $1200, the other 3 $1200 computers plus the 6 $1600 computers}
Notice that y (the number of elements at the left of the median) must be equal to the number at the right of the median.
At the right of the median, we have a total of 9 computers, then y must be equal to 9.
The greatest possible value of y is 9.

The value of each variable in the parallelogram:
h = 9 and g = 61°.
What is parallelogram?A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.
Given:
The shape is a parallelogram.
That means, the opposite sides are parallel and equal.
16 - h = 7
h = 16 - 7
h = 9
And opposite angles of a parallelogram are also equal.

The population of a certain species of insect is given by a differentiable function P , where P(t) is the number of insects in the population, in millions, at time t , where t is measured in days. When the environmental conditions are right, the population increases with respect to time at a rate that is directly proportional to the population. Starting August 15, the conditions were favorable and the population began increasing. On August 20, five days later, there were an estimated 10 million insects and the population was increasing at a rate of 2 million insects per day. Which of the following is a differential equation that models this situation?
a. P=2(tâ5)+10
b. dP/dt=2/5t
c. dP/dt=1/5P
d. dP/dt=5P
Answer:
Option C, dP/dt=1/5P
Step-by-step explanation:
The change is population of insects is directly proportional to the rate of change of population
Hence,
[tex]\frac{dP}{dt} \alpha P[/tex]
Or [tex]\frac{dP}{dt} = kP[/tex]
where K is the proportional constant
We will find the value of k
Keeping the given values of rate of change of population and population in above equation, we get -
[tex]\frac{2}{10} = k\\k = \frac{1}{5}[/tex]
Hence,
[tex]\frac{dP}{dt} = \frac{1}{5} P[/tex]

A leaky 10-kg bucket is lifted from the ground to a height of 12 m at a constant speed with a rope that weighs 0.5 kg/m. Initially the bucket contains 36 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 12-m level. Find the work done. (Use 9.8 m/s2 for g.) Show how to approximate the required work by a Riemann sum. (Let x be the height in meters above the ground. Enter xi* as xi.)
Answer:
The work done is 3645.6 J or 3.6 kJ
Step-by-step explanation:
M1 = (0.5 kg/m)(12 - x m) = (6 - 0.5x) kg
At the height of x meters (0<=x<=12), the mass of the rope is,
M2 = (36kg/12m)(12 - x m) = (36 - 3x m) kg
At the height of x meters (0<=x<=12), the mass of the water is,
M3 = 10 kg
The mass of the bucket is 10 kg
Then, Total mass M is,
M = M1 + M2 + M3 = (6 - 0.5x) + (36 - 3x) + 10 = (52 - 3.5x) kg
From Force F = mass m * acceleration due to gravity g
Force = mass x gravity
F = 9.8(52 - 3.5x) Newtons

Which sum is equal to
8/12
Answer: 2/3
Step-by-step explanation:
For example, if we multiply the numerator and denominator of 2/3 by 4 we get. 2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3.
Answer:
either 4/6 or 2/3
Step-by-step explanation:
Because 12 can be divide in half which is 6, and 8 divided by 2 is 4, so your fraction is now 4/6. if this answer isn't on the screen then you have to do it again: 4 divide by 2 is 2, and 6 divided by 2 is 3, so your fraction is now 2/3.

Vertex:
Answer:
g(x) = (x - 4)^2 - 5, and the vertex is (4, -5)
Step-by-step explanation:
Please, use " ^ " to indicate exponentiation: g(x) = (x - 4)^2 – 5. Comparing this to y = a(x - h)^2 + k, we see that h must be 4 and k must be -5. Thus, the vertex is (4, -5).
Make a table showing several x-values and the corresponding y-values:
x g(x) = (x - 4)^2 - 5 (x, y)
0 (-4)^2 - 5 = 11 (0, 11)
4 (4 - 4)^2 - 5 = -5 (4, -5)

A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days:
f(d) = 9(1.04)d
Part A: When the biologist concluded her study, the radius of the algae was approximately 12.81 mm. What is a reasonable domain to plot the growth function?
Answer:
9 days
Step-by-step explanation:
1= 9*(1.04)^d
12.81/9= (1.04)^d
1.423= (1.04)^d
log(1.423)= d *log(1.04)
0.1532=d * 0.017
d= 0.1532/0.017
d=9
The reasonable domain to plot the growth function is in the interval [0,9].

0.3x=45
0.3x/0.3=45/0.3
