Answer:
2 13/20
Step-by-step explanation:
Answer:
2 13/20
Step-by-step explanation:
we can split up 2.65 into a whole number and a decimal
2.65
= 2 + 0.65 (note that 0.65 = 65/100)
= 2 + 65/100
= 2 65/100 (we can see that both numerator and denominator are multiples of 5, hence we can try to simply by dividing both numerator and denominator by 5)
= 2 (65÷5) / (100÷5)
= 2 13/20 (answer)
f(x)=-x+7 in a table.
Answer:
x, f(x)-2,9-1,80,71,62,5Step-by-step explanation:
A fucntion is basically a machine that follows the instructions it's given and based on those instructions it gives you an answer. So in the function
f(x)=-x+7, our total output (answer) is going to be whatever our "x" is and adding that to 7.
So lets start with -2, plug in -2 for the x variable
f(x)=-(-2)+7, when we solve this we get f(x)=2+7 (negative*negative=positive)
so our final function would be f(x)=9
We can solve the other functions by plugging in the x variable in the same way:
f(x)=-(-1)+7 this simplifies to f(x)=1+7, so f(x) equals 8
f(x)=-(0)+7 this simplifies to f(x)=0+7, so f(x)=7
f(x)=-(1)+7 this simplifies to f(x)=-1+7, so f(x)=6
f(x)=-(2)+7 this simplifies to f(x)=-2+7, so f(x)=5

An eight ft board is cut into two pieces. One piece is 2 ft longer thant he other. How long are the pieces?
Answer: 6 ft and 2 ft
Step-by-step explanation:
Answer:
6ft and 2ft
Step-by-step explanation:
8ft board ÷ 2 pieces = 4ft each
4ft and 4ft boards. But one of them is longer by 2ft so:
4ft - 2ft = 2ft
4ft + 2 ft = 6ft
So, one piece is 2ft and the other piece is 6ft
A square corner of 16 square centimeters is removed from a square paper with an area of 9x2 square centimeters. A square. Most of the square is shaded blue. In the bottom right of the square is a smaller square, outlined in a dashed line, and not shaded. Which expression represents the area of the remaining paper shape in square centimeters? (x – 7)(x – 9) (3x – 2)(3x – 8) (3x – 4)(3x + 4) (9x – 1)(x + 16)
Answer:
(3x - 4) (3x + 4)
Step-by-step explanation:
Area of the square paper = 9x^2 square centimeters
Area of the square corner = 16 square centimeters
The area of the square corner is removed from area of the square paper.
That is,
9x^2 - 16
Factorise by finding the square root of each term
9x^2
Square root of 9x^2 = 3x
Check:
3x * 3x = 9x^2
Square root of 16 = + or - 4
9x^2 - 16 = (3x - 4) (3x + 4)
Check:
(3x - 4) (3x + 4)
9x^2 + 12x - 12x - 16
= 9x^2 - 16

The value of x in the proportion below is option 1 3 1/2.
What is butterfly method?When using the butterfly method approach, the denominator of the first term is multiplied by the numerator of the second term, and vice versa.
What is proportion?An equation known as proportion shows that the two ratios presented are equal to one another. In other terms, the proportion declares that the two ratios or fractions are equal. In terms of proportion, two sets of supplied numbers are said to be directly proportional if they increase or decrease in the same ratio.
The given proportion is:
[tex]\frac{\frac{1}{2} }{4} = \frac{x}{28}[/tex]
Using the method of cross-product or butterfly method:
[tex]\frac{\frac{1}{2} (28) }{4}=x \\\\\frac{14}{4}=x\\ \\x=3.5[/tex]
The value of x is 3.5. Converting this value into mixed fraction:
3.5 = 3 1/2
Hence, the value of x in the proportion below is option 1 3 1/2.

Use the side lengths of triangle DEF and the fact that the triangles are similar to find the measure of angle E and type your answer below. (Note: Do NOT include a unit label in your answer.)
Answer:
Angle E = 65 degrees
Step-by-step explanation:
Since triangle DEF is similar to triangle BAC, angle E = angle A = 180 degrees - angle B - angle C = 180 degrees - 90 degrees - 25 degrees = 65 degrees
HELP!!! What is the equation in point-slope form of the line that passes through point (2,-3) and has a slope of 4
Answer:
y = 4x - 11
Step-by-step explanation:
given slope m = 4
point (2, -3) for (x1, y1)
equation for point slope form
y - y1 = m(x- x1)
y - (-3) = 4 (x -2)
y + 3 = 4x - 8, simplify

1. The sum of 5 and x is 20. What is x?
If the sum of 5 and x is 20, then the value of x will be 15.
It is given that the sum of 5 and x is 20.
Mathematically, it can be written as:
5 + x = 20
We have to find the value of x.
In order to find the value of x we need to separate the variable and constant.
For this, subtract 5 from both the sides:
5+x-5 = 20-5
5-5 +x = 20-5
Then, solve the operation of subtraction on both the sides of above equation.
0+x = 15 -------(A)
Since, when we add 0 to any quantity, the result will be this quantity itself.
So, 0+x = x -------(B)
From (A) and (B), Sine the left sides of equation (A) and (B) are equal, then the right sides will also be equal.
Equation right sides of (A) and (B). We have:
x = 15
Hence, the value of x is 15.

Another term to represent Unit Rate is?
Constant of Proportionality
Slope
Rate of Change All of the Above
None of the Above
Answer:
All of the above.
Step-by-step explanation:
In a graph, the unit rate gives us the change in y for a unit change in x. That is, the unit rate is the rate of change in y when the change in x is 1.
Therefore, the unit rate is the same as the rate of change.
And the rate of change is synonymous with the slope.
The constant of proportionality is simply the slope/rate of change for proportional equations.
Therefore, the constant of proportionality is also another word for the unit rate.
Our answer is hence all of the above.
How long is 75% of a 24-hour day?
Answer:
18 hrs
Step-by-step explanation:
6hrs is 25%, so 6 times 3 is 18, Hope This Helps!
75% of a 24-hour day is 18 hour.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
75% of a 24-hour day
let 75% of 24 hour day be x.
So, 75% of 24 = x
x= 75/100 x 24
x= 3/ 4 x 24
x= 18 hours
Hence, 75% of a 24-hour day is 18 hour.

5^3 / 5^-3 oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
Answer: 5^3 / 5^-3 = 5^6 = 15,625
Step-by-step explanation:
Ok, you may find useful for problems like this the next two relations:
[tex]x^a*x^b = x^{a + b}[/tex]
[tex]x^a/x^b = x^{a - b}[/tex]
Now we have the equation:
5^3/5^-3
We have a quotient, then we need to use the second relationship, where:
x = 5
a = 3
b = -3
5^3/5^-3 = 5^(3 - (-3)) = 5^(3 + 3) = 5^6 = 15,625
