Answer:
700
Step-by-step explanation:
7 tens is 70. 70*10=700.
Answer:
z = 42
Step-by-step explanation:
The question can be answered in 2 steps as follows:
Step 1: Calculation of the constant of the variation
The equation for the joint variation can be given as follows:
z = cxy ................... (1)
Where;
z = 60
c = constant = ?
x = 5
y = 6
Substituting the values into equation (1) and solve c, we have:
60 = c * 5 * 6
60 = c * 30
c = 60 / 30
c = 2
Step 2: find z when x = 7 and y = 3
Since from Step 1 c = 2, we now use equation (1) and substitute the values into it to find z as follows:
z = 2 * 7 * 3
z = 42
Answer: 24 is the LCD
He is correct.
4 20/24 or 4 5/6 simplified
Answer:
the mid point of the segment will be (1,3)
.8
All percents are out of 100, so to figure out the answer you must make the denominator, or bottom number in your fraction, 100.
To get to 100, you would multiply 5x20, because that equals 100. Because you multiplied the denominator, which is 5, you must multiply the top number by 20 as well.
4x20 = 80
So therefore, the answer is 80/100, so .8
