What is the number sentence for "1 less than n is the sum of z and 2?"
[tex]\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}[/tex]
❖ First, Notice it says "1 less than n". This expression indicates that
we subtract 1 from n, which looks as follows:-
[tex]\Large\textit{n-1}[/tex]
❖ Now, It also says "the sum of z and 2". This indicates that we add z and
2:-
[tex]\Large\textit{z+2}[/tex]
❖ Now, Combine these two little expressions into one equation:-
[tex]\implies\sf{n-1=z+2}[/tex]

Answer:
1. False —> that’s how you find the perimeter.
2. False —> area is measured in square units.
3. False —> you can only use a multiplication.
4. True —> (2x6) + (2x8) = 28 inches.
5. False —> 5x5 = 25 square meters.

Have a nice day!!
Answer:
Step-by-step explanation:
1 False. The suggestion given is for Perimeter, not area.
2 False. The perimeter is given in units not square units. For example, the Perimeter of square with one side of 7 in is 4 * 7 inches is 28 inches
3 False. You can only use multiplication equations to find a rectangle's area (or at least it is the easiest way to do it.) Higher math courses find areas by using multiplication and addition, but I'm pretty sure you are not in a higher math course.
4.True
5 False. The area of a square is 5 * 5 = 25. Not 4*5 = 20

we only need to use the formula that can be found easily on the internet.
the area of a circle is
pi×r²
r being the radius (half of the diameter). in our case :
14/2 = 7 m
and we shall use 22/7 as approximation for pi.
so, we get as circle area
22/7 × 7² = 22 × 7 = 154 m²

Answer:
√60
Step-by-step explanation:
6² = 36 ⇒ √36 = 6
8² = 64 ⇒ √64 = 8
⇒ 6 < x < 8
⇒ √36 < x < √64
Therefore, we need the square root of a number between 36 and 64.
From the given options, √60 is the only available option as:
√36 < √60 < √64
⇒ 6 < √60 < 8
Therefore, √60 is greater than 6 and less than 8.
√60
Because
Square of rest two numbers
6²=368²=64As
60 lies in between 36 and 64
So
√60 lies in between 6 and 8.
Ella conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 1 hour. What does this range say about the data?
All the students surveyed spend exactly 1 hour surfing the Internet.
All the students surveyed spend an average of 1 hour surfing the Internet.
The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour.
The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour.
The statement third “the difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour” is correct.
What is range?It is defined as the difference between the maximum value in the data set to the minimum value in the data set.
As we know, the difference between the greatest and lowest values, called the range.
According to this response, the range is 1 hour, which is the difference between the most and least amount of time spent surfing the Internet. This is based on the term “Range.”
Thus, the statement third “the difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour” is correct.

Which graph represents the function f(x) = –x2 + 5? On a coordinate plane, a parabola opens down. It goes through (negative 3, negative 4), has a vertex at (0, 5), and goes through (3, negative 4). On a coordinate plane, a parabola opens up. It goes through (negative 2, 9), has a vertex at (0, 5), and goes through (2, 9). On a coordinate plane, a parabola opens down. It goes through (negative 6, negative 9), has a vertex at (negative 5, 0), and goes through (negative 2, negative 9). On a coordinate plane, a parabola opens up. It goes through (negative 8, 9), has a vertex at (negative 5, 0), and goes through (negative 2, 10).
Answer:
The graph in the attached figure
Step-by-step explanation:
we have the quadratic function
[tex]f(x)=-x^2+5[/tex]
This is a vertical parabola open downward
The vertex is a maximum
Remember that
The equation of a vertical parabola in vertex form is equal to
[tex]y=a(x-h)^2+k[/tex]
where
a is a coefficient
(h,k) is the vertex
In this problem
a=-1
(h,k)=(0,5) ----> vertex
The y-intercept is the point (0,5) ---> value of y when the value of x is equal to zero (is the same point that the vertex)
The x-intercepts are the points --->values of x when the value of y is equal to zero

A box contains orange balls and green balls. The number of green balls is ten more than four times the number of orange balls. If there are 110 balls altogether, then how many green balls and how many orange balls are there in the box?
Answer:
there are 50 orange balls
Step-by-step explanation:
let green balls be x
orange balls be y
green balls = orange balls + 10
x = y+10
orange balls + green balls = 110
x + y = 10
y + 10 + y = 110
2y + 10 = 110
2y = 110 -10
2y = 100
y = 50
thus there 50 orange balls
To multiply 64 • 8.32, use the logarithmic equation:
1) log 72.32
2) log 64 + log 8.32
3) antilog 64 + antilog 8.32
4) (log 64)(log 8.32)
To multiply 64 × 8.32 use the logarithm equation 2)㏒64 + ㏒8.32
To answer the question, we need to know what logarithm of a number is
What is the logarithm of a number?The logarithm of a number x is the power to base 10 of that number.
So, logarithm of x to base 10 is written as ㏒x.
Since we want to multiply 64 × 83.2, we convert this to logarithmic equation using the addition rule of logarithm.
Addition rule of logarithm㏒ab = ㏒a + ㏒b
So, 64 × 8.32 to logarithm is ㏒(64 × 8.32) = ㏒64 + ㏒8.32
So, to multiply 64 × 8.32 use the logarithm equation 2)㏒64 + ㏒8.32
