Answer:
unit rate= 4-kilometers/minute expected time= 56 minutes
Step-by-step explanation:
14 kilometers x 4 kilo/minute = 56 minutes
Answer:
36 and 43
Step-by-step explanation:
let, length be (x+7) and width be x.
here,
perimeter of rectangle=2(l*w)
or,158=2(x+7*x)
or,158=4x+14
or,158-14=4x
or,144=4x
or,144÷4=x
x=36
width=36
length=x+7
=36+7
=43
Answer:
A
Step-by-step explanation:
Answer:
No.
Step-by-step explanation:
The logarithm of a number to the base b of a certain number is the exponent
to which the base b is raised to equal the given value.
So say we have logb y = a, then
y = b^a
So if y = 0 then
0 = b^a
If b is a positive number then there is no value of a that makes y = 0.
for example y = b^0 = 1, y = b^1 = b etc.
Answer:
2⁰ + 2¹+ 2⁵ +2³ = 43
Step-by-step explanation:
since 43 is odd, we know 2⁰ or 1 must be one of the sums
43 - 2⁰ = 42
42 - 2¹ = 40
16 = 2⁴
40-2(16) = 40 - 2⁵ = 8
8 = 2³
adding this all together
2⁰ + 2¹+ 2⁵ +2³ = 43
