Answer:
We want to simplify:
(3 + 1/4)*(3/5)
The first step is to write the first term as a single rational number.
We know that:
3*1 = 3
and 4/4 = 1
then:
3*1 = 3*(4/4) = (3*4)/4 = 12/4
We do this because we want to have the same denominator in both numbers, so we can directly add them.
Then we get:
(3 + 1/4)*(3/5) = (12/4 + 1/4)*(3/5) = (13/4)*(3/5)
And remember that in the multiplication of rational numbers the numerator are multiplied together and the same for the denominators, then we get:
(13/4)*(3/5) = (13*3)/(4*5)
If we solve the multiplications we get:
(13*3)/(4*5) = (39/20)
Now, we can notice that in the numerator we have two prime numbers, 13 and 3.
And in the denominators, we have a 4 (which is equal to 2*2) and a 5.
So the prime numbers in the numerator and the denominator are all different, this means that we can not simplify it furthermore.
Then we have:
(3 + 1/4)*(3/5) = (39/20)

6. Solve for j.
j - 18 = 43
Answer:
j = 61
Step-by-step explanation:
j - 18 = 61
Step One: Add your addend and your total together.
18 + 43 = 61
Step Two/Check: Subtract your original total with one of your original addend to get the second original addend you had before.
61 - 18 = 43
Answer:
j = 61

A 32-foot ladder leans against a building. The distance between the bottom of the ladder and the base of the building is
8.5 feet. What is the height, in feet, from the ground to the place on the building that the ladder touches? Round your
answer to the nearest tenth.
Answer:14
Step-by-step explanation:
happy 5685757
The height at which the ladder touches the building is required.
The height of building where the ladder touches the building is 30.9 feet.
Pythagoras theorema = Required height
b = Distance between the bottom of the ladder and the base of the building = 8.5 feet
c = Length of ladder = 32 feet
From the Pythagoras theorem we have
[tex]a^2+b^2=c^2\\\Rightarrow a=\sqrt{c^2-b^2}\\\Rightarrow a=\sqrt{32^2-8.5^2}\\\Rightarrow a=30.9\ \text{feet}[/tex]

This week, the art museum gave away 1,200 tickets to the Greco exhibit, which was 150 percent as many tickets as it gave away last week. Martin is trying to figure out how many tickets the museum gave away last week. His work is shown below.
Step 1: StartFraction part Over whole EndFraction = StartFraction 150 Over 100 EndFraction = StartFraction question mark Over 1200 EndFraction
Step 2: 100 times 12 = 1200
Step 3: 150 times 12 = 1800
In what step did Martin make a mistake, if any?
Step 1: Martin should have written his ratio as StartFraction 1200 Over question mark EndFraction.
Step 2: Martin should have divided 1200 by 8.
Step 3: Martin should have added 1200 and 150.
Martin did not make any mistakes.

The Earth has a diameter
of 7,917.5 miles. What is
the distance a plane
would have to fly if it
could fly around the entire
equator?
Answer:
L = 24,873.6 miles
Step-by-step explanation:
Length of the Circumference
Given a circle of radius r, the length of the circumference, or line surrounding the shape is:
[tex]L =2\pi\cdot r[/tex]
The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:
r=7,917.5/2=3,958.75 miles
Assuming a plane flies around the equator at ground level, the distance it would travel is:
[tex]L =2\pi\cdot 3,958.75\ miles[/tex]
L = 24,873.6 miles

y = 2
Step-by-step explanation:
y=-2x+6............... equation 1
y=3x-4................... equation 2
from equation 2
y=3x-4
substitute y=3x-4 in equation 1
3x-4=-2x+6
collect like terms
3x+2x=6+4
5x=10
divide both sides by 5
X=2
substitute X=2 in equation 1
y=-2x+6
y=-2(2)+6

If an object was dropped from a height of 405 Meters,find the time it took for the object to hit the ground
Answer:You can use the concept of conservation of total mechanical energy (neglecting the air resistance).
So, initially total mechanical energy = gravitational potential energy (kinetic energy is zero because initially there is no velocity).
Final total mechanical energy = kinetic energy (gravitational potential energy is zero because height has become zero).
So, initial mechanical energy = Final mechanical energy
