The answer is no, he's not correct.
You're looking at 9/1000, which means you move the (invisible) decimal point after 9 three places to the left (because you're dividing and there are 3 zeros after the 1 in 1000). This would give you 0.009.
Answer:
$14.00 per pound for A and $12.50 per pound for B and B is offering the better one since it has a lower cost per pound
Step-by-step explanation:
(5)x19.80=y
(5)x19.80=99
Because the only info given is 19.80 and 5, those are the only definate variables-the total cost is unknown so it is represented by y. To find the total cost, one must multiply the cost of each tickets with how many tickets were bought, represented by (5)x19.80 [the 5 is in parenthesis because it is the independent variable, meaning it changes]. When multiplied together, the equation equals 99, or $99.
2^x = 5
-> log2^x = log5
-> xlog2 = log5
-> x = log5/log2
-> x = 2.322
The approximate answer is 2.322
Answer:
Step-by-step explanation:
<h3>Question 1</h3>
<u>Prove that The two triangles are congruent</u>
- ∠ABD ≅ ∠BDC - given
- BD ≅ DB - reflexive property
- ∠ADB ≅ ∠CBD - given
- ΔABD ≅ ΔCDB - ASA postulate
<u>Find the measure of angle C</u>
- ∠A ≅ ∠C - Corresponding parts of congruent triangles
- m∠C = m∠A = 180° - (62° + 70°) = 180° - 132° = 48°
<h3>Question 2</h3>
<u>Given </u>
Opposite angles are corresponding to the sides.
Therefore the angles opposite to congruent sides are also congruent:
