Abby has 36.4 kg rice at first.
Here,
Abby and Brenda had total 190.4 kg rice.
After Abby gave Brenda 64.5kg rice, Brenda had 6 times as much as Abby.
We have to find amount of rice at first.
What is Total amount?
A total is whole or complete amount, and to total is to add numbers or to destroy something.
Now,
Abby and Brenda had total 190.4 kg rice.
Let amount of rice Abby has = x kg
Let amount of rice Brenda has = y kg
x + y = 190.4 kg .....(i)
Abby gave Brenda 64.5kg rice, Brenda had 6 times as much as Abby.
64.5 + y = 6x
6x - y = 64.5 .....(ii)
From equation (i) and (ii) we get;
x = 36.4
Hence, Abby has 36.4 kg rice at first.

Which is the graph of f(x) = 100(0.7)x? On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 49) and (0, 100). On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 9) and (0, 100). On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 70) and (0, 100). On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 30) and (0, 100). Mark this and return
Answer:
On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 49) and (0, 100).
Which is the graph of the given function?
Here we have the exponential decay:
f(x) = 100*(0.7)^x
So, as x increases, y will tend to zero (because this is a decay, the number with the exponent x is between zero and 1).
Now, if we evaluate in x = 0 we get:
f(0) = 100*(0.7)^0 = 100
Then it goes through the point (0, 100).
If we evaluate in x = 2, we get:
f(2) = 100*(0.7)^2 = 49
Then it also goes through the point (2, 49).
With all that in mind, the correct option is:
"On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 49) and (0, 100)."

Total assets is $20,120; total liabilities is $3,384; net worth is $16,7366; total cash inflows is $3,804; and total cash outflows is $3,920.
How do we calculate the net worth?Total assets = Cash in checking account + Savings account balance + Current value of automobile + Household possessions + Stereo equipment + Home computer + Value of stock investment = $1,340 + $2,770 + $8,020 + $3,510 + $3,320 + $1,160 = $20,120
Total liabilities = Balance of educational loan + Credit card balance = $3,050 + $334 = $3,384
Net worth = Total assets - Total liabilities = $20,120 - $3,384 = $16,736
Cash outflows = Rent for the month + Spending for food + Telephone bill paid for month + Loan pyment + Auto insurance + Payment for electricity + Lunches/parking at work + Donations + Clothing purchase + Restaurant spending = $1,390 + $1,110 + $85 + $143 + $321 + $189 + $204 + $139 + $223 = $3,804

The product of two number is -100. One of the factor is less than 10 and more than 0
The given problem has 4 different solutions as below.
(1, -100)(2, -50)(4, -25)(5, -20)Given that the product of the two numbers is -100.
And one of the factors is less than 10 and more than 0.
Assume c and d are the two required numbers.
Then we have cd = -100, here 0 < c <10.
We know that the factors of 100, which are less than 10 and greater than 0 are 1, 2, 4, and 5.
When c = 1, we get 1 x d = -100 ⇒ d = -100
When c = 2, we get 2 x d = -100 ⇒ d = -100/2 = -50
When c = 4, we get 4 x d = -100 ⇒ d = -100/4 = -25
When c = 5, we get 5 x d = -100 ⇒ d = -100/5 = -20
So, the other factors corresponding to the above factors are -100, -50, -25, and -20.
Therefore, the given problem has 4 different solutions as below.

If two cellphones are randomly selected from the box what is the probability there will be one green cellphnone and one yellow cellphone?
The probability that one green and one yellow is selected (without replacement) is 3/7.
What are examples and probability?
It is predicated on the likelihood that something will occur. The justification for probability serves as the basic foundation for theoretical probability. For instance, the theoretical chance of receiving a head while tossing a coin is 12.Probability that one green and one yellow is selected (without replacement).
Since the cellphone is not replaced, the probability is calculated as follows
Pr = [tex]\frac{G}{n} * \frac{Y}{n - 1 } + \frac{Y}{n} * \frac{G}{n- 1}[/tex] The subtraction means the cellphones are not replaced
This gives
[tex]Pr = \frac{6}{8} * \frac{2}{8 - 1} + \frac{2}{8} * \frac{6}{8 - 1}[/tex]
[tex]Pr = \frac{3}{4} * \frac{2}{7} + \frac{1}{4} * \frac{6}{7}[/tex]
[tex]Pr = \frac{3}{14} + \frac{3}{14}[/tex]
take lcm
[tex]Pr = \frac{3}{7}[/tex]
Hence, the probability that one green and one yellow is selected (without replacement) is 3/7.

What in mathematics is a parallelogram?
A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, and a quadrilateral with equal sides is known as a rhombus.The area is always given by squared units and never by single units!
The area of a parallelogram is given by the equation
A = b * h
b is the base length of the parallelogram

Fahrenheit. During that time, the temperature rose, stayed steady, and fell, at
different rates. On the set of axes below, Hunter created a graph of temperature over time.
How long did the temperature hold steady for??
For 6 hours the temperature is held steady
Solution :
Line Graph:
A line graph—also known as a line plot or a line chart—is a graph that uses lines to connect individual data points. A line graph displays quantitative values over a specified time interval. In finance, line graphs are commonly used to depict the historical price action of an asset or security.
Line graphs can be compared with other visualizations of data including bar charts, pie charts, and (in trading) candlestick charts, among others
Temperature Rose:
It is the increase over ambient temperature of the winding due to energizing and loading
stayed steady:
A steady situation continues or develops gradually without any interruptions and is not likely to change quickly.
Temperature fall :
Temperature drop (T1−T2) is a direct indication of energy extracted. For a given resource, it is dependent on T2 which is in turn dependent on the minimum temperature of the process Ti.
There, we can see that the temperature between 12 noon to 6 pm is not changed much.
therefore we can say that for 6 hours the temperature is holding steady.

A baseball diamond is a square with sides of 90 feet. What is the shortest distance, to the nearest tenth of a foot, between first base and third base?
Hint: the answer will be a 4 digit number, it might include decimals it might not i dunno
Answer:
127.3 feet
Step-by-step explanation:
Use Pythagorean Theorem which says
leg^2+leg^2=hyp^2
90^2+90^2= c^2
8100 +8100=c^2
16200 = c^2
sqrt16200 = c
c ~= 127.27922
Round to one decimal place.
c ~= 127.3 feet
OR, use the shortcut of Special Right Triangles, 45°-45°-90° where, the long side (hypotenuse) is the leg•sqrt2
The legs are 90.
So, the long side is 90•sqrt2
~= 127.27922
~= 127.3 feet

Graph the equation y=-x^2-12x-35 on the accompanying set of axes. You must plot 5 points including the roots and the vertex
Please check the image attached aside with the graph of the quadratic equation.
How to graph a quadratic equation by matching three pointsIn this problem we have a quadratic equation, of which we should plot the graph by matching five points. We can make use of its vertex, two roots, y-intercept and other point. First, determine the vertex of the quadratic function:
- x² - 12 · x - (35 + y) = 0
x² + 12 · x + (35 + y) = 0
12² - 4 · 1 · (35 + y) = 0
144 - 4 · (35 + y) = 0
144 - 140 - 4 · y = 0
4 · y = 4
y = 1
- x² - 12 · x = 36
x² + 12 · x + 36 = 0
(x + 6)² = 0
x = - 6
The vertex of the quadratic equation is (x, y) = (- 6, 1).
Second, calculate the roots of the quadratic equation:
- x² - 12 · x - 35 = 0
x² + 12 · x + 35 = 0
(x + 5) · (x + 7) = 0
The roots of the quadratic equation are (x, y) = (- 5, 0) and (x, y) = (- 7, 0).
Third, determine the y-intercept of the quadratic equation:
y = - 0² - 12 · 0 - 35
y = - 35
The y-intercept of the quadratic equation is (x, y) = (0, - 35).
And fourth, find another point by evaluating the quadratic equation:
y = - 1² - 12 · 1 - 35
y = - 48
The remaining point is (x, y) = (1, - 48).
