Answer:
Step-by-step explanation:
first the parenthesis
3^4/3^0=3^4
anything raised to the power of 0 is 1
(3^4)^2=3^8 you multiply the powers
3^-6 * 3^8= 3^(-6+8)=3^2
Thhe simplified form of the expression is 9
Indices are expressed as power or exponent which is raised to a number or a variable.
According to the law of indices
[tex]a^n \times a^m = a^{n+m}\\a^n \div a^m = a^{n-m}[/tex]
Given the expression
[tex]3^{-6} \times (\dfrac{3^4}{3^0} )^2[/tex]
This can also be expressed as:
[tex]=\dfrac{1}{3^6} \times (\frac{3^4}{1})^2 \ (3^0 =1)\\= \dfrac{1}{3^6} \times 3^8\\=\dfrac{3^8}{3^6}\\=3^{8-6}\\=3^2\\=9\\[/tex]
This shows that the simplified form of the expression is 9

A paper publisher in a medical journal reported that about 11/25 of girls ages 16 to 17 did not exercise at all. The entire study consisted of about 2,500 girls. About how many did not exercise?
Answer:
1400
Step-by-step explanation:
the number of girls aged 16 - 17 that do not exercise = 11/25 x 2500 = 1100
The total number of girls that do not exercise = 2500 - 1100 = 1400
If the edges of a cube are doubled in length to produce a new, larger cube, then the
larger cube's surface area is how many times larger than the smaller cube's surface
area?
take x as the side of the cube.
surface area = 6a^2
= 6x^2
take 2x as the next cube
surface area = 6(2x)^2
= 6 x 4 x x^2
= 24x^2
cube two is 4 times more than cube 1 in surface area wise.

The time at which the temperature was -2.1°C is 5:05 PM
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The temperature is changing at a constant rate of = -0.75° C every half hour
So ,
30 min = -0.75° C
Divide by 3 on both sides , we get
10 min = -0.25°C
So , temperature is changing at a constant rate of = -0.25° C every 10 minutes
Now , the temperature at 6:45 PM = -4.6°C
So ,
The temperature at 6:15 PM = -4.6 + 0.75
= -3.85°C
The temperature at 5:45 PM = -3.85 + 0.75
= -3.1°C
The temperature at 5:15 PM = -3.1 + 0.75
= -2.35°C
Now , for it to be -0.25°C , the time elapsed will be 10 minutes
So ,
The temperature at 5:05 PM = -2.35°C + 0.25°C
= -2.1°C
Hence , the time at which the temperature was -2.1°C is 5:05 PM

Answer:
92.75 cm²
Step-by-step explanation:
area of polygon = area of ∆EDA + area of ∆ADC +area of ∆ACB.
area of triangles is ½×base×height.
area of ∆EDA=½×EF×AD
=½×4.5×12
=27 cm². -------->(1)
area of ∆ADC=½×AD×DC
=½×12×5
=30 cm². --------->(2)
area of ∆ACB=½×AC×BG
=½×AC×5.5
from pythagorean theorem
(AC)²=(AD)²+(CD)²
= 25+144
= 169 cm then. AC= 13 cm
then area of ∆ACB=½×5.5×13
=35.75 cm² ---------->(3)
from equation (1), (2) and (3):
then the area of polygon = 27 + 30 + 35.75
=92.75 cm²
