It takes 45 minutes to drive to the nearest bowling alley taking city streets going 30 miles per hour
(mph). How long will it take to get there using the freeway going 65mph if the distance is the same?
(Round to the nearest minute).
HELLLLPPPPPPP
Answer:
The time it will take to get to the bowling alley while driving at 65 mph on the freeway is approximately 20.8 minutes
Step-by-step explanation:
The given parameters are;
The time it takes through the streets to drive to the nearest bowling alley = 45 minutes
The speed of driving through the streets = 30 miles per hour (mph)
The speed of driving through the freeway to the bowling alley = 65 mph
From the speed of driving through the streets and the time taken we have;
The formula for speed, S, is S = Distance/Time
Therefore, 30 mph = Distance/45 minutes
Where, 1 hour = 60 minutes, 45 minutes = 1/60×45 hour = 3/4 hour
30 mph = Distance/45 minutes = Distance/(3/4 hour)
30 mph = Distance/(3/4 hour)
Distance = 30 mph × 3/4 hour = 22.5 miles
Given that the distance through the freeway and through the streets are the same, we have from speed = Distance/Time;
Time = Distance/Speed
The speed through the freeway = 65 mph while the distance remain 22.5 miles
Therefore;
Time = 22.5 miles/(65 mph) ≈ 0.346 hour ≈ 20.8 minutes
The time it will take to get to the bowling alley while driving at 65 mph on the freeway is approximately 20.8 minutes.

Q11. The ratio of angles of a quadrilateral are
in 3: 5:9:13. Find the angles.
Step-by-step explanation:
Let us take ratio constant as 'x'
Therefore ratio of angles
3x:5x:9x:13x
Sum of interior angles of quadrilateral is 360 degree.
3x+5x+9x+13x=sum of interior angles of quadrilateral
=>3x+5x+9x+13x=360
=>30x=360

Evaluate: 12+(-16)+24-18
Answer:
2.
Step-by-step explanation:
12 + (-16) + 24 - 18
= 36 - 34
= 2.
The value of the expression 12+(-16)+24-18 is 2, which can be computed using the commutative property.
What is the commutative property?The commutative property signifies that the order of terms in mathematical expressions does not matters. It applies only to addition and multiplication operations, and not to subtraction and division operations.
How to solve the given question?In the question, we are asked to evaluate: 12 + (-16) + 24 - 18.
By using the commutative property, we can write the expression
12 + (-16) + 24 - 18, as
= 12 + 24 + (-16) - 18
= 12 + 24 -16 - 18
= 36 - 34
= 2
∴ The value of the expression 12+(-16)+24-18 is 2, which can be computed using the commutative property.

Answer:
t = (D/C - 1) (100/r)
Step-by-step explanation:
D = C(1+rt/100)
D/C = 1 + rt/100
D/C - 1 = rt/100
D/C - 1 = t (r/100)
Therfore,
t = (D/C - 1) / r/100Therefore the last option is correct.

A box is 2m long, 30 cm high and 40 cm wide. What is the volume of the box in cubic centimeters?
Answer:
240000 cm^3
Step-by-step explanation:
For this problem, we need to know that 1 meter is equivalent to 100 centimeters. With this in mind, we can use the equation:
Volume = Length x Width x Height
Volume = 200cm x 40cm x 30cm
Volume = 240000 cm^3

I have a secret number (x). Seven more than quadruple my number equals -5. What is
my number?
Answer:
Your number is 0.5, 2/4, or 1/2
Step-by-step explanation:
You need to set up your equation and then solve for x. We know that quadruple your number (x) plus 7 equals -5. Quadruple your number is the same as multiplying by 4. So it would be 4x + 7 = -5. We add seven to both sides and that would leave us with 4x = 2. Then we divide both sides by 4 to get x on it's own. x = 2/4 or 1/2

What is the image point of (-7,4) after a translation left 3 units and up 5 units
The image point of A ( -7 , 4 ) after a translation of left by 3 units and up by 5 units is ( -10 , 9 )
What is Translation?
A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
Given data ,
Let the point be A ( x₁ , y₁ ) be = A ( -7 , 4 )
Now , the translation of point A ( -7 , 4 ) by left 3 units is
A ( -7 - 3 , 4 )
Now , the new point after the translation by left 3 units
A' ( -10 , 4 )
And the translation of point A' ( -10 , 4 ) by up 5 units is
A'' ( -10 , 4 + 5 )
Now , the new point after the translation up by 5 units is
A'' ( -10 , 9 )
So , the image after the translation of left by 3 units and up by 5 units is
A'' ( -10 , 9 )
Hence , the image after translation is is A ( -10 , 9 )

Tiki gets her hair cut every 4 months and gets a new shirt every 3 months. How many months a year with she get her hair cut and buy a new shirt in.the same month
Answer: Every 12 months (aka once a year)
=======================================================
Explanation:
List out the multiples of 4 and 3
Multiples of 4 = {4, 8, 12, 16, 20, 24, ...}
Multiples of 3 = {3, 6, 9, 12, 15, 18, 21, 24, ...}
The terms in bold are the common multiples between the two lists. The smallest or lowest common multiple (LCM) is 12. Every 12 months, or every 1 year, Tiki gets her hair cut and a new shirt in the same month.
-----------
A shortcut to find the LCM is to multiply the values 4*3 = 12. This only works when the GCF of the two original numbers is 1.
