Answer:
Step-by-step explanation:
If we're asked to use any positive value. It means we could have a wide variety of answer. A positive value of k that makes the equation 20k to be less than 20, yet greater than zero has to be any decimal value or a fraction, if you so wish.
As an example, if k is 0.5. Then we have
20k = 20 * 0.5 = 10, which is less than 20 and greater than zero
Again, if k is 0.9. Then we have
20k = 20 * 0.9 = 18, which is less than 20 and greater than zero.
So, you use any decimal number greater than 0, yet less than 1

PROBLEM:
Jenni's mother sent her to the Farmers Market to buy 5 pounds(lbs.) of
potatoes. The market sold potatoes by the ounce (oz.) Jenni asked Farmer
Brown for 5 pounds of potatoes. Farmer Brown gave Jenni 64 ounces of
potatoes. Jenni noticed that she did not get 5 lbs. of potatoes. How many
more ounces does she need so that her mother can make 5 lbs. of french
fries?
Answer:
16 ounces
Step-by-step explanation:
1 pound = 16 ounces
16*5 = 80 ounces
5 pounds = 80 ounces
80-64 = 16 ounces

A hovercraft takes off from a platform. It's height (in meters), x seconds after takeoff, is modeled by h(x)=-(x-11)(x+3) How many seconds after takeoff will the hovercraft land on the ground?
Answer:
11seconds
Step-by-step explanation:
Given the height of the hovercraft expressed as;
(x)=-(x-11)(x+3)
The height of the hovercraft on the ground is 0, hence;
0 =-(x-11)(x+3)
-(x-11)(x+3) = 0
Multiply both sides by minus
(x-11)(x+3) = 0
x-11 = 0 and x+3=0
x = 11 and -3
Since time cannot be negative, hence the hovercraft will land after 11seconds
Henrietta did an experiment. She started out with 800 bacteria cells. She found that the growth rate of the bacteria cells was 3.2%. Sketch the graph that represents the situation. Label the y-intercept and the point that represents the projected bacteria population 35 h from the time Henrietta started the experiment. I need help asap please
Answer:
See belowStep-by-step explanation:
Given
Initial number of bacteria = 800Growth rate = 3.2% = 1.032 timesRequired equation:
B(t) = 800(1.032)^t, where B- number of bacteria, t- time in hoursThe y-intercept is:
B(0) = 800*1.032^0 = 800The point (0, 800)Bacteria population 35 in hours:
B(35) = 800*1.032^35 = 2409The point (35, 2409)4. One week Lin's balance at the start of the week was (- $16) but she

Dylan draws up a plan to fence in a yard for his chickens. This distance between grid lines is 1 foot. A. Is 30 feet of fencing enough to enclose the yard?
Please I need help!!!!!
Answer:
Solution given:
we have
f(x)=x²-9x-36
let
y=x²-9x-36
when
x=0
y=-36
when
y=0
0=x²-9x-36
x²-12x+3x-36=0
x(x-12)+3(x-12)=0
(x-12)(x+3)=0
either
x=12
x=-3
So,
x and y intercepts are (-3,0)(12,0) and 0,-36)

Please help, my brain just sucks rn. The area of a rectangle is 93.6 square inches. If the length of one of its sides is 5.2 in. what is its perimeter?
46.4 inch
Step-by-step explanation:
Area=l×b
93.6 =5.2×b
93.6/5.2 =b
So b= 18
Again,
p=2(l+b)
p=2(18+5.2)
p= 2×23.2
p=46.4

What is the solution to the given system of equations?
y=4x-28
y=1.5x-18
1(-12,4)
2.(2,-12)
3.(7,0)
4.(7.5,2)
Answer:
Solution (4, -12)None of the listed choices are a solution
Step-by-step explanation:
y = 4x - 28
y = 1.5x - 18
Set the equations equal since both equal y
4x - 28 = 1.5x - 18
Subtract 1.5x from both sides
2.5x - 28 = -18
Add 28 to both sides
2.5x = 10
Divide both sides by 2.5
x = 4
---------------------
use x= 4 in either equation
y = 4x - 28
y = 4(4) - 28
y = 16 - 28
y = -12
--------------------
Solution (4, -12)
The ratio of the weights of A and B is equal to the ratio of the weights
of C and D. If A is 20 kg, B is 24kg and C is 40 find out the value of D .
Answer:
D = 48kg
Step-by-step explanation:
The ratio of the weights of A and B is equal to the ratio of the weights
of C and D.
From the above question
A : B = C : D
This can also be interpreted as
A/B = C/D
A is 20 kg
B is 24kg
C is 40kg
D is ?
Therefore:
20/24 = 40/D
Cross Multiply
20D = 24 × 40
D = 24 × 40/20
D = 48
Therefore, D = 48kg

Hello! answer: x = 12
Step-by-step explanation:
with these you have to cross multiply so 2 x 24 = 48 so now we know that 4 multiplied by something will equal 48 so we can simply do this by doing 48 ÷ 4 and 48 ÷ 4 = 12

6. The swing set on the playgrounds is getting wobbly, and you have been asked to put outrigger boards to help stabilize it. If the crossbar of the swing is 10 feet off of the ground, the outrigger to be attached at a 40 degree angle, and you want to bury the outrigger boards 3 feet onto the ground, how long would the boards have to be? (Hint: the outrigger is the hypotenuse of a right triangle)
Answer:
[tex]X=18.6ft[/tex]
Step-by-step explanation:
From the question we are told that:
Height of swing's crossbar [tex]H=10ft[/tex]
Angle [tex]\theta=40 \textdegree[/tex]
Depth of outrigger [tex]d_=3ft[/tex]
Generally the equation for slant height l is mathematically given by
[tex]l=\frac{opposite}{sin\theta}[/tex]
Therefore
[tex]l=\frac{H}{sin\theta}[/tex]
[tex]l=\frac{10}{sin 40\textdegree}[/tex]
[tex]l=15.6ft[/tex]
Since the Depth of outrigger
[tex]d_=3ft[/tex]
Therefore Length of the board X
[tex]X=l+d[/tex]
[tex]X=15.6+3[/tex]
[tex]X=18.6ft[/tex]

A bag with 10 marbles has 2 yellow marbles, 4 blue marbles, and 4 red marbles. A marble is chosen from the bag at random. What is the probability that it is yellow?
Answer:
P(Y) = 2/10 = 1/5
Step-by-step explanation:
From the above question:
Total number of marbles = 10 marbles
Number of yellow marbles = 2 yellow marbles
Number of blue marbles = 4 blue marbles
Number of red marbles = 4 red marbles.
The probability of choosing a marble that is yellow is calculated as:
= P(Y) = Number of yellow marbles/Total number of marbles
P(Y) = 2/10
P(Y) = 1/5
