Sugar Shack Cookies had 5 types of cookies in its display case. The number of each cookie sold during day one is recorded. Find the percent of chocolate chip and oatmeal raisin cookies sold.
Answer: 40%
Step-by-step explanation:
Chocolate chip and oatmeal cookies: 9+35 = 44
Total cookies = 9+21+15+35+30 = 110
What percent is 44 of 110 (%/100 = is/of)
x/100 = 44/110 (cross multiplication)
4400/110 = 40
What is the solution to the following system?
X+2y+z=9
X-y+3z=13
2z=10
Answer: x = 0; y = 2; z = 5
Step-by-step explanation:
x+2y+z=9
x-y+3z=13
2z=10
==
Start with the last equation: 2z = 10, therefore z = 5 [easy]
Let's rewrite the second equation with 1) z=5, and 2) rearrange to find x:
x-y+3z = 13
x - y +3*5 = 13
x = y-2
Now use the values for x [(y-2)] and y [5] in the first equation:
X+2y+z=9
(y-2) +2y + 5 = 9
3y +3 = 9
3y = 6
y = 2
Now that we have y [2] and z [5], let's use the first equation to solve for x:
x+2y+z=9
x + 4 + 5 = 9
x + 9 = 9
x = 0
====
Try the three values (x=0, y=2, and z=5) in any of the formulas. The result should/will equal the number shown.

Show that a to the 6th an be written as a perfect square and as a perfect cube.
Answer:
Step-by-step explanation:
a^6 = a * a * a * a * a * a You can break this into groups of 2 and groups of three.
Groups of 3
a^6 = a * a * a * a * a * a
what that means is that you have 2 groups of 3 which can be written as (a^3)^2 which means that this number is a perfect square.
Groups of 2
a^6 = a * a * a * a * a * a
What this means is that you have (a^2)^3 which is three groups of 2 members. The answer is that you have a perfect cube each member of which is a^2

Identify and estimate the x- and y-values of the extrema. Round to the nearest tenth if necessary.
The stationary or turning points on a graph are known as its extrema
Taking each axis division as representing one unit, we have;
The global extrema are; (-2, -4) and (2, -4)
The local extrema is the point (0, 4)
The reason the above values are correct is as follows;
The extrema is the plural form of the calculus term extremum for the point on the graph of the function where the value of the function is the maximum or largest value or the minimum or the smallest value
At the extremum, the value of the function stops increasing or decreasing and starts decreasing or increasing after the extremum respectively
From the given graph, we have that the global extrema where there are minimum values are;
x = -2, and y = -4, which gives the point (-2, -4)
x = 2, and y = -4, which gives the point (2, -4)
Therefore, the global extrema are; (-2, -4) and (2, -4)
The local extremum is the point x = 0, and y = 4 or (0, 4)

find the endpoint if A (5,-2) and the midpoint is B (3,6), what is C
Answer:
C = (1, 14 )
Step-by-step explanation:
The coordinates of the midpoint are the average of the x and y coordinates of the endpoints.
Find the average of endpoints and equate to coordinates of midpoint
A (5, - 2 ) , let C = (x, y ) , then
[tex]\frac{x+5}{2}[/tex] = 3 ( multiply both sides by 2 )
x + 5 = 6 ( subtract 5 from both sides )
x = 1
and
[tex]\frac{y-2}{2}[/tex] = 6 ( multiply both sides by 2 )
y - 2 = 12 ( add 2 to both sides )
y = 14
Coordinates of C = (1, 14 )

The angles ABM and MBC sum to the measure of angle ABC. Let's create an equation to model the problem.
ABM + MBC = ABC
Let's plug our values into the variables.
ABM + 150 = 171
Let's solve for ABM. Subtract 150 from both sides.
ABM = 21
Answer:
∠ ABM = 21°
Step-by-step explanation:
∠ ABM + ∠ MBC = ∠ ABC , that is
∠ ABM + 150° = 171° ( subtract 150° from both sides )
∠ ABM = 21°

Write the expression (−7)·(−7)·5·5·5·5 using exponents.
The expression (-7)·(-7)·5·5·5·5 can be written using exponents as: [tex](-7)^2 * 5^4[/tex].This is because (-7)·(-7) is equal to [tex](-7)^2[/tex], and 5·5·5·5 is equal to [tex]5^4[/tex].Writing expressions using exponents is a way to represent repeated multiplication in a more concise form.
Exponents indicate how many times a base number is multiplied by itself. Here's how you can write expressions using exponents:
Base: This is the number that you're going to multiply repeatedly.
Exponent: This is the small number written above and to the right of the base. It represents how many times the base is multiplied by itself.
Some key points to remember:
Multiplication with the same base: When you have the same base number multiplied multiple times, you can use an exponent to represent it more compactly.
Negative Exponents: Negative exponents indicate that the base is in the denominator. For example, x^-3 is equivalent to 1/x^3.
Fractional Exponents: Fractional exponents indicate roots. For example, x^(1/2) is the square root of x.
Operations with Exponents: When you have expressions with exponents and you're performing operations like addition, subtraction, multiplication, or division, you need to follow the rules of exponentiation.
