Evaluate the expression: 2{ a( 2b + 3c)} for a=8, b=3, and c=4
Answer:
288
Step-by-step explanation:
Evaluate Using the Given Value
2 (a (2b + 3c)) for a = 8 , b = 3 , and c = 4
Replace the variable a with 8 in the e xpression.
2 ((8) (2b + 3c))
Replace the variable b with 3 in the expression.
2 ((8) (2 (3) + 3c))
Replace the variable c with 4 in the expression.
2 ((8) (2 (3) + 3 (4)))
Simplify each term.
Multiply 2 by 3.
2 (8 (6 + 3 (4)))
Multiply 3 by 4.
2 (8 (6 + 12))
Simplify the expression. Tap for fewer steps...
Add 6 and 12.
2 (8 ⋅ 18)
Multiply 8 by 18.
2 ⋅ 144
Multiply 2 by 144.

A circles circumference is approximately 76cm. Estimate the radius, diameter and area of the circle.
Answer:
The circumference of a circle is C = 2πr^2 (2nd power) Radius (r) is the distance from the center of the circle to the outside of it. To find radius divide the diameter (d) by 2. The diameter (d) of a circle is the radius (r) multiplied by 2. To find the diameter (d) you need to do C ÷ π.
For example):
Finding diameter - 76/3.14 = 24.19 (d)
Finding radius - 24.19/2 = 12.095 (r)
EDIT: (C) Means Circumference
A psychology teacher gave a test to 200 students, and, after seeing the results, decided that the scores were
normally distributed. The mean score was 60, and the standard deviation was 10. How many students had scores
between 40 and 80?
Answer:
Step-by-step explanation:
66-95-99.7 rule
standard deviation is 10. meaning that it'll deviate twice meaning you use the 95%
95% of 200 is 190, so 190 students had scores between 40 and 80

describe how to solve a system of equations using elimination
Answer: In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Write the coordinates of the point C after dilation with scale factor of 5, centered at the orgin
Answer:
Coordinates of point C after dilation with a scale factor of 5, centered at the origin will be: C'(10, 5)
Step-by-step explanation:
Given the point C
C(2, 1)A dilation with a scale factor of 5 means the size of the coordinates of the image of point P will be 5 times larger than than the original coordinates of point C.
Thus, the rule of dilation by a scale factor 5 is:
(x, y) → (5x, 5y)
C(2, 1) → (5x, 5y) = (5(2), 5(1)) = C'(10, 5)
Therefore, coordinates of the point C after dilation with a scale factor of 5, centered at the origin will be: C'(10, 5)

If 37.5% of the 600 shoppers stated they would buy the new flavor, how many of the 600 would buy it?
Answer:
225 lo comprarían
Step-by-step explanation:
Para sacar el porcentaje se multiplica el numero por el porcentaje y dividir entre 100
37.5x600/100
37.5x 600= 22, 500
22,500/100= 225

)Hannah's electricity company charges her $0.15 per kWh (kilowatt-hour) of electricity, plus a basic connection charge of $25.00 per month. Write a linear function that models her monthly electricity bill as a function of electricity usage.
Answer:
Linear function: y = 24x + 25
Step-by-step explanation:
24 hours = 1 day
30 days = 1 month
0.15 x 24 = 6
30 x 6 = 180
180 + 25 = 205
Linear function: y = 24x + 25

Answer:
(1) 56 miles/hour
Step-by-step explanation:
We need to find the average rate of change from t = 2 to t = 9.
At t = 2 hours, d = 106 miles.
At t = 9 hours, d = 498 miles.
The average rate of change in function f(x) from x = a to x = b is
[f(b) - f(a)]/(b - a)
average rate of change from t = 2 to t = 9 =
(498 - 106)/(9 - 2) = 392/7 = 56
Answer: (1) 56 miles/hour

A. The coefficients of (x + y)" are given by the nth row of Pascal's
triangle.
B. Each row is a "palindrome" – that is, it is the same if read from
left to right or from right to left.
C. The nth row gives the coefficients in the expansion of (x + y)21.
D. To generate Pascal's triangle, add adjacent terms on a row to
determine the term directly below them.
