Eli broke a cell sample into 14 batches, each weighing 4.7 x 10-8 grams. How much
did the original sample weigh? Use scientific notation to express your answer.
The weight of the original sample from which all 14 batches in the task content is; 65.8 x 10-8 grams.
What is the fundamental principle of multiplication?If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
WE have been given that Eli broke a cell sample into 14 batches, each weighing 4.7 x 10-8 grams. which follows that the task content; the weight of the original sample from which the eight batches were obtained be determined.
Hence, since each of the 14 batches weighs;
[tex]4.7 \times 10^{-8}[/tex]
Therefore, the weight of the original sample can be obtained as;
[tex]4.7 \times 10^{-8} \times 14\\\\65.8 \times 10^{-8}[/tex]
However, when the weight is expressed in scientific notation, thus the weight of the original sample is;
[tex]65.8 \times 10^{-8}[/tex]
Hence, The weight of the original sample from which all 14 batches which each weighed 4.7 x 10-8 grams are obtained as required in the task content is; 65.8 x 10-8 grams.

The monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes). The monthly cost for 53 minutes of calls is $12.03 and the monthly cost for 65 minutes is $13.59. What is the monthly cost for 57 minutes of calls?
The monthly cost of 57 minutes calls is $12.55.
The monthly cost is $12.03 for 53 minutes and $ 13.59 for 65 minutes call
Therefore we have two points (53, 12.03) and ( 65, 13.59)
slope = (13.59 - 12.03)/ ( 65 - 53)
= 1.56/ 12
= 0.13
The intercept is
y = mx + c
12.03 = 0.13×53 + c
12.03 = 6.89 + c
c = 5.14
Equation:
cost = 0.13(minutes) + 5.14
= 0.13×57 + 5.14
= 7.41 + 5.14
= 12.55
Therefore the monthly cost for 57 minutes is $12.55.

What is component form?A vector's component form is the ordered pair that explains the changes in the x- and y-values. A vector v's component form is written as v=vx,vy, where vx represents the horizontal distance between the initial and terminal points and vy represents the vertical displacement between both the initial and terminal points.To find the component form of magnitude 10 and direction 42°:
component form = x + iy
Then,
x = 10 cos 42° = 7.43 = 7.4y = 10 sin 42° = 6.69 = 6.7Component form: 7.4 + 6.7iTherefore, 7.4 + 6.7i is the component form of the given magnitude and direction

O 14x-21 = -6
O 1-2-x1=9
O 13x + 61 = 6
O 1-2x + 81 = 0
Equation has no solution is |4x-2|=-6
checking option A
|4x-2|=-6 . . . .1
if 4x-2≥0
4x≥2
x≥1/2
then |4x-2| = 4x-2
So , .. . . 1 becomes

x=-1
But x≥1/2
So x=-1 is not a solution.
if 4x-2≤0

then |4x-2| = -(4x-2)
So , .. . . 1 becomes
-4x+2=-6
4x=8
x=2
but x≤1/2
So x=2 is not a solution.

|-2-x| = 9 . . . 2
if -2-x ≥ 0
x≤-2
then
|-2-x| = -2-x
So, . . .. . 2 becomes
-2-x=9
x=-11
so it has a solution .
checking option C
|3x+61| = 6 . . . . . 3
if 3x+61≥0
x≥-61/3
then
|3x+61| = 3x+61
So, . . .3 becomes
3x+61=6
x=-55/3
So it has a solution.

A large jar contains an unknown number of red gumballs and 145 green gumballs. As part of a seventh-grade class project the teacher asks Carlos to estimate the total number of gumballs in the jar using a sample. Carlos draws a sample of 55 gumballs, of which 11 are red and 44 are green. Use Carlos' sample to estimate the number of gumballs in the jar.
The total number of gumballs in the jar calculated using probability is about 181.
Probability is the study of chance. The likelihood of an event to occur given as a fraction is probability.
For a sure event the probability is 1 and for an impossible event the probability is 0.
Carlos draws a sample of 55 gumballs. Out of which the number of green gumballs is 44.
Probability of a green gumball= number of green gumballs ÷ total number of gumballs
P(green) = 44 ÷ 55 = 4/5
Now in the sample the number of green gumballs is 4/5 , and in the jar the number of green gumballs is 145 .
Let us consider there are x gumballs in total in the jar.
P(green)=145 ÷ x
We know that P(green)= 4/5
∴4/5 = 145 ÷ x
or, x = 145 × 5 ÷ 4
or, x = 181.25 gumballs.
or, x ≈ 181 gumballs(As the number of gumballs cannot be a fraction)
Therefore there are about 181 gumballs in total .

A 75% antifreeze solution is to be mixed with a 90% antifreeze solution to get 360 liters of a 85% solution. How many liters
of the 75% and how many liters of the 90% solutions will be used?
In linear equation , 240 liters of 90% solutions will be used.
What are a definition and an example of a linear equation?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.Let x be the quantity of 75% antifreeze solution and y be the quantity of 90% antifreeze solution,
Since, the total quantity of the mixture = 360,
⇒ x + y = 360 ----- (1),
Also, the resultant solution is of 85% antifreeze solution,
⇒ 75 % of x + 90% of y = 85% of 360
0.75x + 0.90y = 0.85 × 360
0.75x + 0.90y = 306
75x + 90y = 30600 -----(2),
Equation (2) - 75 × equation (1),
We get,
15y = 3600
⇒ y = 240
Hence, 240 liters of 90% solutions will be used.

[tex]\boxed{\text{Midpoint}=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )}[/tex]
Let the other endpoint be (x, y).
Substitute the given midpoint and one endpoint into the formula above:
(-6, 4)= [tex](\frac{x+4}{2},\frac{y+8}{2} )[/tex]
Comparing the x-coordinate:
[tex]-6=\frac{x+4}{2}[/tex]
Multiply both sides by 2:
x +4= -12
Subtract 4 from both sides:
x= -12 -4
x= -16
Comparing the y-coordinate:
[tex]4=\frac{y+8}{2}[/tex]
Multiply both sides by 2:
y +8= 8
Subtract 8 from both sides:
y= 8 -8
y= 0
