Answer:
20 cm
Step-by-step explanation:
A prism's volume is found using the formula A = B*h where B is the are of the base. Here the volume v = 250 and the B = 12.5. Substitute the values and solve for h.
250 = 12.5*h
250/12.5 = h
20 = h
Answer:
A = 51.3°, B = 90°, C = 38.7°
Step-by-step explanation:
The given lengths satisfy the Pythagorean theorem:
(√41)² = 4² +5² ⇒ 41 = 16 +25
so we know the triangle is a right triangle. The right angle is opposite the longest side, so is angle B, opposite side AC.
The remaining angles can be found using trig functions. For example, we know ...
tan(A) = BC/AB = 5/4
A = arctan(5/4) ≈ 51.3°
Then the other acute angle is ...
C = 90° -51.3° = 38.7°
Angles A, B, C are ...
(A, B, C) = (51.3°, 90°, 38.7°)
<u>Answer</u>
18) $51
19) $24
20) <em> Carla's account. </em>
<u>Explanation</u>
18)
Positive sign values means deposit while the negative values means money been withdrawn from the account.
$100 - $18 + $22 - $53 = $51
19)
Positive sign values means money deposited while the negative values means money been withdrawn from the account.
$45 - $17 - $22 + $18 = $24
20)
To get the person with the most deduction, you should add the negative values in the table then compare.
Carla ⇒ -18 + -53 = $-71
Leta ⇒ -17+ -22 = $-39
From here we can see that the account with greatest decrease is<em> Carla's account. </em>
Each year is 12 months and each month we exercise for 24 hours so for one year we gonna exercise for : 12 × 24 = 288 hours :))
