Answers:
1.)529.934 sq feet
2.) $185,260
3.)(usd) $349.59 per square foot
Explanation:
1.) 1 meter is 3ft and 3.37 inches. All you have to do is multiply that by 160
2.)one euro is worth 1.18 usd, so all you have to do is multiply the amount of euros (157,000) by 1.18
3.) this uses a combination of what we have gotten. You have to divide the total price in usd (185,260) by the amount of square feet there are (529.934)
Answer:
x = 10.9
Step-by-step explanation:
Since the triangle is right, use the tangent ratio to find the value of x
tan36° = 
= 
= 
Multiply both sides by 15
15 × tan36° = x
⇒ x = 10.9 ( to nearest tenth )
Answer:
Louis needs to save 15+39 = $ 54 dollars
Step-by-step explanation:
\begin{aligned} 15 + 39 &=& \\ 10 + 5 + 30 + 9 &=&\\ 10 + 30 + 5 + 9 &=&\\ 40 + 10 + 4 &=&\\ 54. \end{aligned}
So Louis needs to save \$54.
The first answer is c

A powerful way to find out is to solve the equation. Let's try that.
3 (d + 11) = 6 (d + 33)
Eliminate the parentheses: 3d + 33 = 6d + 198
Subtract 3d from each side: 33 = 3d + 198
Subtract 198 from each side: -165 = 3d
Divide each side by 3 : - 55 = d
There it is ... the solution to the original equation.
'd' has to be -55, otherwise the original equation isn't a true statement.
-55 is the ONLY number that 'd' can be. If you write in any other number
for 'd', the equation will be false.
For example, less see what the equation says when d=2 :
3(2 + 11) = 6(2 + 33)
3( 13 ) = 6( 35 )
39 = 210
Is that a true statement ? Is 39 equal to 210 ?
No. 39 and 210 are not equal. They are different.
So the equation is not true when d = 2 .
The equation is true ONLY when d = -55 .
The equation has exactly one solution.
