The expression which converts the height of the bookcase to feet is 1.93 × (3.2808ft / 1m)
To make the conversion of meters to feets , we use dimensional analysis ;
We need to multiply the given measurement in meters by its appropriate or equivalent value in feets :
Recall :
1 meter = 3.2808 feets
Then the height of the bookcase in feets will be :
1.93 meters × 3.2808ft / 1m
Hence, the appropriate expression is : 1.93 meters × 3.2808ft / 1m

The subtraction problem 11.5−7.2 can be rewritten as the addition problem _[blank]_.
The subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression of subtraction is,
E = 11.5−7.2
The expression in the form of addition will be converted by changing the sign of 7.2.
E= 11.5 - (-7.2)
E = 11.5 + 7.2
Therefore, the subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.

Answer both please asap
There are five ways to colour the centre square.
Suppose we colour the left hand side. Since the colours of the strip are symmetrical, the number to colour the right hand side is 1.
For the left part where there are 14 squares, let's consider the most adjacent square to the centre. There are four ways to colour that square since it cannot have the same colour as the centre square.
The same goes with the other squares remaining.
So, the answer is 5×4^14.

Answer: 47.25
Step-by-step explanation:
the equation for finding the area of a triangle is base times height divided by 2
10.5(9)= 94.5
94.5/2=47.25
Answer:
47.25 sq ft is the area. no idea what you want me to do with the 4% though
Step-by-step explanation:
area for traingles = (base×hight)÷2
so your equation would he (10.5ft×9ft)÷2
10.5×9= 94.5
94.5÷2÷47.25
so the answer is 47.25 ft^2 (or simply sq ft)

What is 4 log Subscript one-half Baseline w + (2 log Subscript one-half Baseline u minus 3 log Subscript one-half Baseline v) written as a single logarithm? 4 log Subscript one-half Baseline 2 Superscript 4 Baseline u squared minus v cubed
The correct answer is B).
The single solution is [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex].
What is logarithmic?The exponent to which the base of the logarithm should be raised in order to obtain the number N is the logarithm of any number N, if interpreted as an exponential form. Numerous astronomical and scientific calculations involving large numbers can benefit from its use. As an inverse of the exponential function, logarithmic functions are closely related to exponential functions.
Given Equation
[tex]4log_\frac{1}{2} w + (2log_\frac{1}{2} u - 3log_\frac{1}{2} v)[/tex]
[tex]mlog_an = log_an^{m}[/tex]
equation is
[tex]log_\frac{1}{2} w^4 + (log_\frac{1}{2} u^2 - log_\frac{1}{2} v^3)[/tex]
and [tex]log_an - log_am = log_a\frac{n}{m}[/tex]
and [tex]log_an + log_am = log_amn[/tex]
[tex]log_\frac{1}{2} w^4 + (log_\frac{1}{2} \frac{u^2}{v^3} )[/tex]
and [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex]

You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional. So set up two ratios that are = to each other
On the left
long side small triange / long side large triangle = base small triangle / base large triangle
On the right
hypotenuse/longest leg = hypotenuse / longest leg.
Problem A
Set up the similar Proportion
5/40 = x/20 Cross Multiply
40x = 20*5
40x = 100 Divide by 40
x = 100/40
x = 2.5
Problem B
Again set up the similar triangle proportion
15/10 = x/2 Multiply by 2
15*2/10 = x
3 = x

A number has many factors including 3 and 8. What other number must also be a factor of the same number?
Two "factors" are multiplies together to product another number (the product). So, for example, the prime factors of 10 are 2 and 5. Prime factors that, themselves, have only factors of 1 and themselves. Non-prime numbers, like 10, have prime factors. Note that 1 is a factor of all integers.
If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root."
Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).
Practice:
What is the square root of 49?
What is the square root of 100?
What is the square root of 625?
Memorize the squares of the numbers from 1 to 10, or 1 to 20 -- that will be very helpful in math classes.

Step-by-step explanation:
When doing divison of fractions, you do these steps
11/3 ÷ 2/3 you turn the division sign to a multiplication sign, but by doing that you will have to turn 2/3 to 3/2.
11/3 × 3/2. Now all you have to do is multiply

Answer:
4 hectaresStep-by-step explanation:

k = 1/400Applied to the area we consider k² as the area is the product of two dimensions.
Find the actual area:
0.25 m² : (1/400)² = 0.25 m² * 160000 = 40000 m² = 40000 * 1/10000 hectares = 4 hectaresWILL MARK BRAINLIEST! Solve for X and Y
