If Rita has driven 30 miles so far (three-fifths of the way home), you can calculate what is the total length of her drive using the following steps:
x ... total length
three-fifths of the way home = 30 miles
3/5 of x = 30 miles
3/5 * x = 30 /*5/3
x = 30 * 5/3
x = 50 miles
The total length of her drive is 50 miles.
Answer:
152 Chairs
Explanation:
7 rows of 23 chairs: 7 · 23
7 · 23 = 161
Remove 9
161 - 9 = 152
Answer:
The numbers increase by 3
Step-by-step explanation:
The difference between all the numbers in the sequence have a gap of 3
9 and 12 --gap of 3
12 and 15--gap of 3
18 and 21--gap of 3
21 and 24--gap of 3
Y= -2(x²-x)+2= -2(x-1/2)²+2+1/2= -2(x-1/2)²+5/2
<span>x=6, y= -2(11/2)²+5/2= -121/2+5/2= -58
I hope this helps</span>
Answer:
The options are not clearly written but, the volume of square based pyramid is 1/6 the volume of a cube because each of the six faces of the cube will contain one square based pyramid.
Step-by-step explanation:
Let the length of each side of your cube be x
the height of each of the six enclosed pyramids would be x/2. So the volume of each pyramid would be given by:
V = (1/3) × base area × height
V = (1/3) × x^2 × (x/2) = (x^3)/6
