Answer:
823/30
or 27 13/30
decimal: 27.43
Step-by-step explanation:
(25+7)+ (1/6 + 2/5)
32+ (5/30 + 12/30)
32+ 17/30
= 32 17/30
60- 32 17/30
= 1800/30 - 977/30
= 823/30
= 27 13/30
Write the algebraic expression for... 16 less than a number n
Answer: n-16
Step-by-step explanation:
The algebraic expression for 16 less than a number n is thesame thing as subtracting 16 from n which will be represented as: n - 16.
Therefore, the algebraic expression for 16 less than a number n will be = n - 16

Which system of linear inequalities is represented by the graph?
y > x – 2 and y x + 1
y x + 1
y > x – 2 and y < x + 1
Answer:
D) y > x – 2 and y < x + 1
Step-by-step explanation:
- Graph each system of linear inequalities.
- Examine each graphed system of linear inequalities
- Match the system of linear inequalities that looks the same as the graph shown
Remember:
> and < are dashed lines
≥ and ≤ are solid lines
if y is ≥ or > , then the shaded region is above the graphed line
if y is ≤ or <, then the shaded region is below the graphed line
m = slope
b = y intercept
change the inequality sign into an equal sign to check the y intercept.
use the equation y = mx + b to check each one

Step-by-step explanation:
Function w gives the weight of a cat, in kilograms, when it is m months old.
Which statement represents the meaning of the equation w(7) = 4 in this situation?
A) The cat weighs 7 killograms when it is 4 months old.
B) The cat weighs 4 kilograms when it is 7 months old.
C)The weight of the cat has been 7 kilograms for 4 months.
D) The cat weighs 4 kilograms when it is 7 years old.
Option B) The cat weighs 4 kilograms when it is 7 months old. is correct answer.
Given that:w gives weight of cat, in kgs, when it is m months old.
To find:What does w(7) = 4 represents.
Explanation:It is already given that w gives weight in kilograms.
It outputs weight when we tell the age in months, thus, this is what we treat as input.
w(7) means weight when cat is 7 months old.
and w(7) = 4 represents that the cat weighs 4 kilogram when the age of cat is 7 months.
Thus, Option B) The cat weighs 4 kilograms when it is 7 months old. is correct answer.

https://brainly.com/question/24846347
The correct option is Option B) The cat weighs 4 kilograms when it is 7 months old.
The following information should be considered:
The equation is w(7) = 4.Here car weight should be 4 kilograms at the time of 7 months old. Since w denotes the weight of the cat and m denotes the months.Learn more: https://brainly.com/question/4804019?referrer=searchResults

Answer:
x = 62
Step-by-step explanation:
Since the 2 legs of the triangle are congruent, both 6 , then the triangle is isosceles and the base angles are congruent, that is
x = [tex]\frac{180-56}{2}[/tex] = [tex]\frac{124}{2}[/tex] = 62

A circular wire of length 176 cm is rebound to a rectangle whose length is same as the diameter of the circle. Find the difference in both the areas ?
Answer:
The difference in area is 672 cm^2
Step-by-step explanation:
Firstly, let us get the diameter of the circle
The length of the wire is the measure of the circle’s circumference
mathematically;
C = pi * d
176 = 22/7 * d
22d = 7 * 176
d = (7 * 176)/22
d = 56 cm
So, the area of the circle will be;
pi * d^2/4
= 22/7 * 56 * 56 * 1/4
= 2464 cm^2
Also, the length of the circumference is same as the perimeter of the rectangle
From the perimeter of the rectangle, we can get the width and use that to calculate the area of the rectangle
The formula for the perimeter of the rectangle is;
2(l + b)
2(56 + b) = 176
56 + b = 88
b = 88-56
b = 32 cm
So, the area of the rectangle will be;
32 * 56 = 1792 cm^2
The difference between the two areas will be;
2464-1792 = 672 cm^2

Answer:
Find answers below
Step-by-step explanation:
First know that any value raise to power zero is 1 and also according to the inverse law;
a⁻ⁿ = 1/aⁿ
Given the following
a) (-123)⁰ = 1 ()Note that any value raise to zero is 1
b) 43⁻⁵ = 1/43⁵
1/43⁵ = 1/147,008,443
c) 1/15⁻⁶ = 1/(1/15⁶)
1/(1/15⁶) = 1*15⁶/1
1/(1/15⁶) = 15⁶
d) -(1353348)⁰
= -1 (anything raise to zero is 1)
e) 13⁻⁴ = 1/13⁴
= 1/28,561

A. (-1,2) and (3, 2)
B. (-2, -4) and (2, 4)
C. (-2, 1) and (2, 1)
D. (-1, -2) and (3, 6)
Answer:
D. (-1, -2) and (3, 6)
Step-by-step explanation:
y = 2x
y = x² - 3
2x = x² - 3
x² -2x - 3 = 0
(x + 1)(x - 3) = 0
x = -1 or x = 3
y = -2 or y = 6

A flower shop sells 11 different bouquets and multiple different styles of vase. Which are the possible numbers for the total number of combinations of bouquet and vase?
Total combinations would be found by multiplying the number of different bouquets by the number of different vases.
The problem doesn't say how many different vases there are so using the letter v for vases, multiply 11 by v
Total combinations = 11v

what is x?
Answer:
Step-by-step explanation:
is it one to one or onto? why?
Answer:
Step-by-step explanation:
Given quadratic function is,
f(x) = -x² - x + 1
Range of the function has been defined as (-∞, [tex]\frac{5}{4}[/tex] ]
Domain of the function is a set of all real numbers.
From the graph of this function,
At x = -3 and x = 2, value of y = -5
But for one to one functions, every x value should map to a different value of y.
Therefore, function is not one to one.
Since, every value of domain (x-value) maps the range (y-value) in the given range (-∞, [tex]\frac{5}{4}[/tex] ], function will be defined as onto.
Therefore, this function is ONTO, but NOT ONE TO ONE.
