Answer:
62.000124 in. cubed
Step-by-step explanation:
cm to inches: 0.3937007874 to 1
the side edges are 3.937007874
Since it's a square pryramid, all of the side lengths are equal. 3.937007874^2 is 15.500031.
The formula for a pyramid: base*height/3
15.500031*12/3 = 62.000124 in. cubed
In a store, 9/200 of the shirts are pink and 69/600 are orange. What percent of the shirts are not pink or orange?
Answer:
84%
Step-by-step explanation:
The percentage of pink shirts
= 9/200 × 100%
= 9/2
= 4.5%
The percentage of orange shirts
= 69/600 × 100%
= 69/6
= 11.5%
The percentage of the shirts which are not pink or orange
= 1 - 4.5% - 11.5%
= 84%
Alternative
Find their common denominator.
9/200
= 9×3 / 200×3
= 27/600
The total percentage of shirts in pink and orange
= (27/600 + 69/600) × 100%
= 96/600 × 100%
= 16%
The percentage of the shirts which are not pink or orange
= 1 - 16%
= 84%

Step-by-step explanation:
(2x+3x) x 3+15=12x+36
Answer:
Is this what you meant?
(2x + 3x) × (3 + 15) = 12x + 36
(5x) × (18) = 12x + 36
90x = 12x + 36
78x = 36
x = 36 / 78
x = 18 / 39
_____________________
or
3(2x+3x) + 15 = 12x + 36
10x + 15 = 12x + 36
-21 = 2x
2x = -21
x = -21/2
David drove 36 mph and reached camp in 1.5 hours. How long will it take him to drive home if he takes the same route and drives 45 mph?
Answer:
1.2 hours, or 72 minutes
Step-by-step explanation:
If David drove for 1.5 hours at 36 mph, that means that he traveled a distance of (36*1.5) = 54 miles.
If he takes the same route at a speed of 45 mph instead, he will reach his destination in (54/45) = 1.2 hours, which is equivalent to 72 minutes.
Answer:
1.2 hours
Step-by-step explanation:
to find distance for 36 mph
0.5 hour is 18 miles
so 36m+18m
= 54 miles for 1.5 hours
and to find time for 45 mph
[tex]54 \div 45 = \frac{6}{5} \\ = 1.2[/tex]

Ivan knows two sides of a triangle are 16 meters and 6 meters. What two values must the third side be between
Answer:
Third side lies between 10 & 22.
Step-by-step explanation:
Any side of triangle is greater than difference of two sides. Sum of two sides of triangle is always greater than third side.
So, letting third size be = x
Difference of two sides < Third side x < Sum of two sides
Difference of two sides = 16 - 6 = 10 , Sum of two sides = 16 + 6 = 22
Hence, 10 < Third side x < 22

At a football stadium, 10% of the fans in attendance were teenagers. If there were 100 teenagers at the football stadium, what was the total number of people at the stadium?
Answer:
The answer is 1000.
*Explanation*
Attendance at the football stadium is 100%
100% - 10% = 90%
10% = 100 attendance
900% = 900 attendance
900 + 100 = 1000 attendance

(I’ll mark brainliest ) The cross country running team is hosting their first home race and needs to plan and set up the course. The only tool available to record the distance measures in feet. If the course must be at least 3 miles but no more than 3.2 miles in length, what is the smallest and the largest number of feet they must walk in order to fulfill the requirements?
1 mile 5,280 feet.
Smallest:
Largest:
Answer:
Smallest: 15,840 ft
Largest: 16,896 ft
Step-by-step explanation:
1 mi = 5,280 ft
Setup proportion to solve for the smallest:
[tex]\frac{1mi}{5,280ft} =\frac{3mi}{xft}[/tex]
Do butterfly method and you should get this:
[tex]xft=3(5280)\\x=15,840ft[/tex]
Setup proportion to solve for the largest:
[tex]\frac{1mi}{5,280ft} =\frac{3.2mi}{xft}[/tex]
Butterfly method:
[tex]xft=3.2(5280)\\x=16,896ft[/tex]

How do I find the point of intersection?
Answer:
(-1 3/5, 2 3/5)
Step-by-step explanation:
Red Line:
m = 3-(-1)/-2-2 = 4/-4 = -1
b = 1
equation: y = -x + 1
Blue Line:
m = 5-1/2-(-4) = 4/6 = 2/3
find 'b':
5 = 2(2/3) + b
15/3 = 4/3 + b
b = 11/3
equation: y = 2/3x + 11/3
Find Point of Intersection:
-x + 1 = 2/3x + 11/3
multiply each side by 3 to get:
-3x + 3 = 2x + 11
-5x = 8
x = -8/5
find 'y':
y = -(-8/5) + 1
y = 8/5 + 1 = 13/5
y = 2 3/5
