B. A polygon is either a square or a rectangle
Answer:
4 ft 2 in.
Step-by-step explanation:
A door to a playhouse is 50 inches tall
we know that
1 in---------------> is 0.0833333 ft
so
50 in-------------> 50*0.0833333---------> 4.167 ft
4.167 ft----------> [4 ft+0.167 ft]
remember that
1 in---------------> is 0.0833333 ft
X in----------------> 0.167 ft
X=0.167/0.0833333----------> X=2 in
4.167 ft----------> [4 ft+0.167 ft]--------> [4 ft+2 in]
5/49(x)<span> = 20/7
5x/49 = 20/7
</span>5x/49 × 49 = 20/7 <span>× 49
</span>5x = 140
5x / 5 <span> = 140 / 5
</span>x = 28
Answer:
<em>k=-3</em>
Step-by-step explanation:
<u>Equation of a line</u>
The general equation of a line can be written as:
Ax+By=C
The x-intercept is the point where the line crosses the x-axis, i.e. y=0, thus replacing x=3 and y=0:
A(3)+B(0)=C
3A=C
Solving for A:
A=C/3
The y-intercept is the point where the line crosses the y-axis, i.e. x=0, thus replacing x=0 and y=5:
A(0)+B(5)=C
5B=C
Solving for B:
B=C/5
Replacing into the general equation:
Simplifying by C:
The point P(k,10) belongs to the line, thus:
Operating:
Multiplying by 3:
Answer: 31 cents
Step-by-step explanation: Since sales tax is 6%, in decimals, that is 0.06. Then you multiply the total of the bill by the tax amount to get how much she will be paying in tax.
5.20 x 0.06 = 0.312
Then you round to the nearest hundreth since you can't have a fraction of a cent to get 0.31
