June started washing the window at 12:20 PM.
June washed the window for 2 Hours and 45 minutes.
As he finished washing the window at 3:05 PM
For calculating at what time did he start washing the window we need to subtract the time taken in cleaning the window from the time at which he finished washing.
As, for finding the starting time, we need to subtract 2 Hr. and 45 minutes from 3:05 PM.
As, 3:05 PM can be also written as 5 minutes post 3 which will be equivalent to (60+5) = 65 minutes post 2. (As there are 60 minutes in 1 Hr).
Now, 45 minutes before 2:65 minutes will be 2:20
Again 2 Hr. before 2:20 PM will be 12:20 PM.

Step-by-step explanation: So, when finding exponents, you have to multiply the # in parentheses (in this case, -3) and multiply it by itself 4 times, so once is 3 x 1, twice is 3 x 3 = 9, three times is 9 x 3 = 27, and finally, 27 x 3 = 81.

if a vehicle is going 75 mph, how many feet does it travel in one second? 110 feet 660 feet 330 feet 550 feet
The vehicle travels 110 feet distance in 1 second duration.
What is mean by mph?mph expresses the speed or velocity in miles per hour. Speed means rate of change of distance with respect to time.
speed = distance/time
hence, distance = speed x time
the above equation is the relationship between distance, speed and time
How can we calculate distance in feet?we will use the above equation and convert miles to feet and second to hour.
given, speed of vehicle = 75 mph
time = 1 second =1/3600 hour as 1 hour = 3600 second
distance travel by vehicle = speed x time
= 75 mph x 1/3600 hour
distance = 0.020833333 miles
we know, 1 mile =5280 feet
distance in feet = 110 feet

We determined the conditional probability of drug assigned people who survived at least 5 years = 101/344
What is conditional probability?The possibility of occurring an event connected to the previous other event. That means occurring of two events is related to each other.
How to determine conditional probability of the question?We determine the probability by the following way.

Read the following statement: If A is an acute angle, then m2A = 30°. This statement demonstrates:
the substitution property.
the reflexive property. the symmetric property. the transitive property.
Answer:
Its been a minute since I've done this math
Step-by-step explanation:
This statement demonstrates the substitution property.
The substitution property states that if two expressions are equal, then we can substitute one expression for the other in any equation or inequality. In this case, "A" is an acute angle, and "m2A" is the measure of twice that angle. The statement says that if we double the measure of an acute angle, the result will be 30 degrees. Therefore, we can substitute "m2A" for 30 degrees in any equation or inequality.
The reflexive property states that any number or object is equal to itself. The symmetric property states that if a = b, then b = a. The transitive property states that if a = b and b = c, then a = c. None of these properties are demonstrated in the given statement.

The sin (theta) = -2/5, and theta lies in quadrant IV. Find the exact values of the sine and cosine of 2 theta.
Answer: first choice!
sin2Theta= -4rt21/25
cos2Theta = 17/25
Step-by-step explanation:
Use Double Angle Formulas.
You can find cos2Theta immediately because one of the formulas needs only sin(theta) and that was given.
Cos2Theta =
1 - 2(sinTheta)^2
= 1 - 2(-2/5)^2
= 1 - 2(4/25)
= 1 - 8/25
= 25/25 - 8/25
= 17/25
The only answer with cos2theta=17/25 is the first choice.
Use a simple graph and Pythagorean Theorem to find cos(theta). Then you can use the Double Angle Formula for sin2theta. This would kinda be a double check if you have time. Since the first part of the solution eliminated all choices except the first choice, if you're pressed for time just do cos2theta calculation and pick the first choice.
See image for sin2theta calculation.

The punnett square shows the results when two parent dogs are crossed. L represents the allele for a long tail, and l represents the allele for a short tail. Which best describes this inheritance pattern? incomplete dominance because neither allele for tail length is dominant codominance because neither allele for tail length is dominant incomplete dominance because the offspring display an intermediate form of tail length codominance because the offspring display an intermediate form of tail length.
The best description for the inheritance pattern will be incomplete dominance because the offspring display an intermediate form of tail length.
The relationship is referred to be "complete dominance" when the phenotype (the observable trait) of the heterozygote is identical to the dominant homozygote. Complete dominance isn't necessarily the result, but rather imperfect supremacy, as heredity is full of variances and changes.
Although we are aware of total dominance, you might still be unclear as to how partial dominance varies. Is it essentially what the name implies? When one allele for a certain trait is not completely dominant over its counterpart, this is known as partial dominance (or the other allele). The outcome is a mixed phenotype, which is evident in the progeny.
Why does this matter? Each parent's characteristics are neither dominant nor recessive. A third phenotype that combines the traits of the two homozygotes results from a partial dominance relationship between two alleles; this is known as a "intermediate form of inheritance." The features are combined and appear to be "blended," but the alleles do not blend yet, partial dominance is frequently referred to as "blending."

If Sue's home is the origin and the positive direction is assumed to the right, then her position is 2 mi.
Therefore, the answer is 2mi.
Origin depends on the frame of reference, it depends on from where the observer is viewing.
From the figure, distance between home and Sue = 2 - 0 = 2mi
and the distance between Cinema and Sue = 5 - 2 = 3mi
Sue's position is 2mi right to her home and 3mi left to the Cinema. So if her home is the origin and positive direction is to the right x is +2 mi.

RP=18/0.80
RP=$22.50
Answer:
22.50
Step-by-step explanation:
other answer is cryptic so here is a full explaination
To find the regular price of the hat, we need to determine the amount of the discount and then add that amount to the discount price.
The discount on the hat is 20% of the regular price, or 20/100 * regular price. The discount price is $18, so we can set up the equation:
discount price = regular price - (20/100 * regular price)
Substituting the known values into the equation, we get:
$18 = regular price - (20/100 * regular price)
Solving for the regular price, we find that the regular price is $22.50. This is the price of the hat before the discount.

Given all angle information, the assumption that sides [tex]\overline {BC}[/tex] must not be congruent to [tex]\overline{DA}[/tex] to give an appropriate answer. (Right choice: None)
How to determine what side is the shortest one in a quadrilateral
Any quadrilateral can be divided into two triangles by adding a diagonal. By Euclidean geometry, the sum of the measures of internal angles equals 180°. Likewise, we can determine how short or long a side is in terms of side BD by law of sine:
AD / sin 60° = AB / sin 63° = BD / sin 57°
1.155 · AD = 1.122 · AB = 1.192 · BD
AD = 0.971 · AB = 1.032 · BD
BC / sin 57° = CD / sin 55° = BD / sin 68°
1.192 · BC = 1.221 · CD = 1.079 · BD
BC = 1.024 · CD = 0.905 · BD
By direct inspection and use of equality properties, we find the existence of an absurdity, because 1.032 · BD = 0.905 · BD, then [tex]\overline {BC}[/tex] must not be congruent to [tex]\overline{DA}[/tex] to satisfy all angle conditions.
