Answer: 3:5
Step-by-step explanation:
33x-54y=6x+6y-3x-10y
33x-54y=3x-4y
30x=50y
3x=5y
Answer:
115°
Step-by-step explanation:
The above shape is a quadrilateral.
A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.
The sum of interior angles of a Quadrilateral is 360°
Therefore,
115 + 65 + 65 + m = 360
245 + m = 360
m = 360 - 245
m = 115°
Therefore, m< B = 115°
Answer:
B
Step-by-step explanation:
A contrapositive statement is one that switches the hypothesis and conclusion of a conditional statement and negates both. In our hypothesis,
"If it is past 5:00 p.m., Megan’s office building is not empty", we shall break it into two statements and show the contarpositive of each like shown below.
Hypothesis Contrapositive
Megan’s office building is not empty- Megan’s office building is empty
It is past 5:00 p.m - it is not past 5:00 p.m
And thus the contrapositive statement becomes
If Megan’s office building is empty, then it is not past 5:00 p.m.
Answer:

Step-by-step explanation:
we know that
To make one hair ties is needed 3 3/8 inches of elastic
so
using proportion
Find out how many hair ties can you make with 9 feet of elastic
Remember that

Convert 9 ft to inches

Convert mixed number to an improper fraction

using proportion

Let's take a look at the exponent rule:

Her mistake was she multiplied the exponents instead of adding it up.
