A serving of rice is 2/3 of a cup. How many servings are there in a 2 2/3-cup bag of rice?
Answer:
4 servings
Step-by-step explanation:
You do 2 2/3 divided by 2/3. First you change 2 2/3 to 8/3. Now, you change 2/3 to it's reciprocal; 3/2. Now you change division to multiplication and find your equation; 8/3 x 3/2. You cancel out both the threes, and find 8/2, or simplified, 4.
Answer:
4 servings
write 2/3x4, put 1 under 4
2x4=8
3x1=3
8/3
8/3 simplified is 2 2/3

Patrick has assets that total $9,500. his liabilities total $1,900. which expression will find patrick’s net worth? 9,500 dollars divided by 1,900 dollars 1,900 dollars minus 9,500 dollars 1,900 dollars minus 9,500 dollars 9,500 dollars minus 1,900 dollars
An expression has numbers, variables, and mathematical operations. Patrick's net worth is represented by the expression $9,500-$1,900.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As it is given that the value of the assets with Patrick is $9,500, while the liabilities are $1,900. Thus, his net worth will be the difference between his assets and his liabilities.
Thus, Patrick's net worth of Patrick can be written as,
[tex]\rm Net\ worth = Assets-Liabilities[/tex]
[tex]= \$9,500-\$1,900[/tex]
Thus, Patrick's net worth is represented by the expression $9,500-$1,900.

3, 1,1/3
The sequence 3, 1,1/3 is a geometric sequence
The 7th term of the sequence is 1/243
How to determine the 7th term?The sequence is given as:
3, 1,1/3
The above sequence is a geometric sequence with the following parameters:
First term, a= 3Common ratio, r = 1/3The nth term is then calculated as:
Tn = ar^(n-1)
So, the 7th term is:
T7 = ar^6
Substitute known values
T7 = 3 * (1/3)^6
This gives
T7 = 1/3^5
Evaluate
T7 = 1/243
Hence, the 7th term of the sequence is 1/243

The scatter plot below shows the cost (y) of long distance phone call based on the number of minutes (x) the calls take. Part A. Draw a line of best fit on the scatter plot
Part B write the approximate equation of the line of best fit
It should be in slope intercept form.
Part C. Use your equation from part B to predict the cost of a long distance call that lasts 120 minutes. Be sure to show your work
Part D. Explain how you found your answer to Part C.
The scatter plot that shows the cost of long distance phone call is an illustration of a linear regression
Part A: Draw a line of best fitSee attachment for the line of best fit
Part B: The equation in slope intercept formFrom the attached graph, the line passes through the points:
(x,y) = (0,0) and (40,4)
The equation is then calculated using:
y = y2/y1 * x
This gives
y = 4/40 * x
Evaluate
y = 0.1x
Part C: Predict the cost of long distance call of 120 minutesThis means that x = 120
So, we have:
y = 0.1 * 120
y = 12
Hence, the predicted cost of long distance call of 120 minutes is $12
Part D: Explanation of CThe answer in part C is calculated by substituting 120 for x in the equation of the line of best fit

Please solve this on paper! I'll give brainliest to the best explanation. Thank you so much <3
Answer:
The measure of angle 7 is 47°
The value of x = 69
Step-by-step explanation:
(a) The measure of angle 7 is also 47° { therefore angle 5 angle 7 are vertically opposite angles so they are equal }
(b) if the angle 6 is represented by (2x-5) so the equation will be (2x-5) + angle 5 = 180° { linear pair}
(c)
=> 2x-5+47 = 180
=> 2x + 42 = 180
=> 2x = 180 -42
=> 2x = 138
=> x = 138/2
=> x = 69
Answer:
See below ↓↓↓
Step-by-step explanation:
(a) ∠7 = ∠5 (vertically opposite angles)
∠7 = 47°It is equal to 47 degrees, because the when a transversal cuts through a straight line, the angles which lay opposite to each other are equal(b) ∠5 and ∠6 form a line, so their sum is equal to 180°, which is the angle of a straight line. Therefore, our equation :
47 + 2x - 5 = 180(c) Solving for x :
2x + 42 = 1802x = 138x = 69°A box contains 20 balls, of which are white. If the probability of selecting a non-white

We're looking for the magnitude of the force - angles don't matter.
We need to resolve the two forces.
As you can see in the attached drawing, this basically just becomes Pythagoras.

If (8,b) Is a solution to the equation represented by the graph below, what is the value b?
Answer:
b= -18
Step-by-step explanation:
See attached image.
Formulate the equation for the line by calculation the slope and adding the y-intercept, as shown. The y-intercept if the value of y when x = 0. The equation of a straight line is y=mx+b, where m is the slope and b is the y-intercept. Note that this b is not the same b in the question (8,b). The b in the question may be calculated once the equation is found: y = -3x+6, where -3 is the slope and 6 is the y-intercept (0,6).
Use x = 8 in this equation. y = -3(8)+6, y = -18
The point is (8,-18), so b is -18.

1. When oil was spilled out in the middle of a lake, it spread out on the surface of the water in a circular pattern. The radius of the circular pattern increased at a rate of 4 feet per minute. ((() = 4tft/min)
A. [3 pts) How fast was the area of the circular pattern increasing per minute? Construct the composite function to show how the area was increasing each minute. ( A() = ft/min).
The rate of change of the area as a function of time is:
A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)
How to get the rate at which the area increases?
Remember that for a circle of radius R, the area is:
A = 3.14*R^2
Now, if the radius increases at a rate of 4 ft/min, then we can rewrite R as:
R(t) = R₀ + 4ft/min*t
Where t is the time in minutes, and R₀ is the initial radius.
So the area function is:
A(t) = 3.14*(R₀ + 4ft/min*t)^2
The rate of change is given by the differentiation with respect to t, it is:
A'(t) = 2*3.14*(R₀ + 4ft/min*t)*(4ft/min)
A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)
The rate at which the area increases, as a function of time, is given by:
A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)

Alice is making a necklace. She has a chain that is 400 mm long. She puts forty 1.7 mm beads, twenty-seven 6.5 mm beads, and eight 3.4 mm beads on the chain. How much of the 400 mm chain is left without bead?
Answer:
129.3mm chain left without beads
Step-by-step explanation:
Equation:
400mm long chain - [(40 x 1.7mm) + (27 x 6.5mm) + (8 x 3.4mm)]
= chain left without beads
Calculation:
40 beads x 1.7mm = 68mm
27 beads x 6.5mm = 175.5mm
8 beads x 3.4mm = 27.2mm
(68mm + 175.5 mm + 27.2mm) = 270.7mm chain with beads
400mm chain - 270.7mm chain with beads
= 129.3mm chain left without beads
