Answer:
30.67 feet
Step-by-step explanation:
A proportion is often useful for solving scale drawing problems.
actual size : drawing size = (room length) : (23 in) = (2 ft) : (1.5 in)
Multiplying by 23 in gives ...
room length = (2 ft)(23 in)/(1.5 in) = 46/1.5 ft = 30 2/3 ft
room length ≈ 30.67 ft.
An if-then statement must hold under any condition. Let's take it case by case:
A. This one makes sense, and is perfect! If two angles are vertical, then they must be congruent. This holds no matter what. This is your answer.
B. This doesn't hold because Alternate Interior Angles can also be congruent (along with many others). Two angles don't <em>have </em>to be vertical to be congruent.
C. This one is also true because this is the contrapositive of Option A. (Read my reasoning on D to know what a contrapositive is). Therefore, this is correct.
D. This one is the contrapositive of B, which makes it the exact same as B. Thus, this is not the answer. Contrapositive, by the way, just means that it's the inverse and opposite of a given statement. Let's say P is the contrapositive of Q. If this is the case, then if Q is true, P must be true. In our case, Option D is the contrapositive of Option B and since Option B is not true, neither is D.
Answer:
i believe it is B.
I could be wrong, D is my second choice. but since (left to right) its decreasing, im 89% sure it is B 1/9.
Answer:
(3x + 8) = 50
(5x - 20) = 50
(5x + 4y) = 130
Step-by-step explanation:
3x + 8 = 5x - 20
2x = 28
x = 14
5(14) + 4y + 5(14) - 20 = 180
y = 15
Answer:
b
Step-by-step explanation:
he makes 80 dollars for a normal shift
20 dollars for every phone he sells 20m
and e is the total amount
e=20m+80
