Answer:
m∠SRZ=40°
Step-by-step explanation:
The figure shows rectangle RSTW which has the angle RTW with measure of 40°.
1. Sides SR and TW are parallel as opposite sides of rectangle, then angles SRZ and RTW are alternate interior angles. By alternate interior angles theorem, they are cingruent, so m∠SRZ=40° . This option is true.
2. Angles STZ and RTW aro complementary (add up to 90°), then
m∠STZ=90°-40°=50°. This option is false.
3. Angle SRW is a right angle (in rectangle all angles are right angles). By the definition of right angle,
m∠SRW=90°. This option is false.
4. Angle TWR is a right angle (in rectangle all angles are right angles). By the definition of right angle,
m∠TWR=90°. This option is false.
Look at the first digit after the decimal. That digit (if there is no whole number), is in the tenths place, and will, if there is a greater number, let you know which one is the greatest.
D) 0.6 is your answer, because it is greater than all the other numbers by at least 1.

The main formulas of log are:
log A + logB =log A*B
log A - logB =log A/B
log A ^p= p logA
so
log_4(7)+log_4(5)=log_4(7*5)=log_4(35)<span>
log_8(11)-log_8(5)=log_8(11/5)
2log_9(3)=log_9(3)²</span>
Answer:
Not sure I understand your question.
If the tax rate is 6.25% and you need the tax from $73.97, tax is:
= 6.25% * 73.97
= $4.62
Converting 6.25% to decimal.
First understand that when a percent sign(%) is next to a number it means that the number is a fraction and its denominator is 100.
6.25% = 6.25/100
To convert to decimal, divide the numerator by the denominator:
= 6.25 ÷ 100
= 0.0625
