The formula is : A=6a^2
So lets say its a cube with edge lengths of 4
We first find out the area of each side by multiplying 4*4
They you multiple the answer of that, 16, by 6, for each of the sides.
A = 96 Units ^2
Answer:
Neither
Step-by-step explanation:
It has a y intercept, which is -6, which changes the whole graph, so its neither
Answer:
31\frac{1}{2}ft^2
Step-by-step explanation:
From the information given each of the three rectangular countertops has dimension 4\frac{3}{8} by 2\frac{2}{5} feet.
The area of a rectangular shapes is the product of the dimensions.
Each rectangular countertop has area;
4\frac{3}{8}\times 2\frac{2}{5}=\frac{35}{8}\times \frac{12}{5} =10\frac{1}{2}ft^2
Therefore the number of square feet tiles needed to cover all the countertops is D.
Answer:
slope = -9/2
Explanation:
The form of the slope-intercept equation is:
y = mx + c
where:
m is the slope
c is the y-intercept
The given is:
y = -9/2 x
Comparing the given with the general form, we will find that:
m is the slope = -9/2
c is the y-intercept = 0
Hope this helps :)
y = -9/2
Answer:
Step-by-step explanation:
The data of timing for each lap will form a arthmetic progression ( AP ) with first term as 25 s and common difference of 1.6 s .
a )
first term a = 25
common difference d = 1.6 .
10 th term of the series can be given by following formula
a₁₀ = 25 + ( 10-1 ) x 1.6
= 25 + 1.6 x 9
= 39.4 s
b )
Let n th be the last lap
a(n) = a + ( n-1 ) x d
55.4 = 25 + ( n- 1 ) x 1.6
n - 1 = 19
n = 20 .
c )
sum of all the term of AP
=( first term + last term ) x no of term / 2
= (25 + 55.4 ) x 20 / 2
= 804 s .
= 804 / 60 min
= 13.4 min .
