We know that a rectangle has 2 pairs of opposite equal sides and all interior angles are right. A rhombus has 4 equal sides. So if a quadrilateral is both a rectangle and a rhombus, it must have 4 equal sides and 4 interior right angles. That quadrilateral must be a square.

What is log Subscript 15 Baseline 2 cubed rewritten using the power property?
nalin [4]

Answer:

The equivalent expression

Step-by-step explanation:

Assuming your expression is \log_{15}2^3, then we can use the power property of logarithm , which is \log_ab^n=n\log_ab.

If we let a=15, b=2, and n=3

Then using the power property of logarithm will give us:

\log_{15}2^3=3\log_{15}2

Using the power property of logarithm, the equivalent expression is 3\log_{15}2

A software store has put some of its inventory on sale. Games are marked down by 15%, and security programs are marked down by 1
Katyanochek1 [597]

Answer:

Option D. \$11.34

Step-by-step explanation:

Let

x -----> the original price of one game

y ----> the original price of one security programs

Remember that

100\%-15\%=85\%=85\100=0.85

100\%-18\%=82\%=82\100=0.82

The total pay with discount is

\$35.70+\$22.96=\$58.66

we have that

0.85(2x)=35.70\\1.70x=35.70\\x=\$21

0.82y=22.96\\y=\$28

Find the total pay without discount

2x+y=2(21)+28=\$70

The amount saved is the difference

\$70-\$58.66=\$11.34

The daily energy requirement, E (kilojoules), for a person of mass m ( kilograms) is calculated using the rule E=9m+8100
Wewaii [24]
For this case we have the following equation:
 E = 9m + 8100
 Substituting E = 8865 we have:
 8865 = 9m + 8100
 Clearing m we have:
 9m = 8865-8100
 m = (8865-8100) / (9)
 m = (765) / (9)
 m = 85 Kg
 Answer:
 
Gavin's mass is:
 
m = 85 Kg
