Answer:

-0.5 and negative one-half

-1/50 and -0.02

Step-by-step explanation:

-0.5 can be rewritten as -5/10. This can be simplified to -1/2 which is the same as negative one-half.

7/10 isn't equivalent to 11/20. If you multiply 7/10 by 2/2 to get the denominator of 20, it will become 14/20 not 11/20.

-1/50 in decimal form is -0.02 so -1/50 and -0.02  are equivalent.

0.15 and 1/5 aren't equivalent because 1/5 in decimal form is is 0.2, not 0.15.

The area of a rectanglular sandbox is (5x + 40) feet. Factor 5x + 40 to find possible dimensions of the sandbox
kotegsom [21]
5x+40 factors to 5(x+8). Notice how distributing the 5 back through to each term in the parenthesis gives
5 times x = 5x
5 times 8 = 40
So 5*(x+8) = 5*x+5*8 = 5x+40

Therefore, the factors are 5 and (x+8).
The dimensions of the sandbox are 5 feet by (x+8) feet.

We don't know the numeric value of (x+8) since we don't know the value of x, so we leave it as is.

The sum of the measures of the interior angles of a convex polygon is 3960°.
scZoUnD [109]

Step-by-step explanation:

The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.

A bacteria population is 3000 at time t = 0 and its rate of growth is 1000 · 8t bacteria per hour after t hours.
julia-pushkina [17]
P=3000x e^( 1000 x 8t )is the function
t is time, so "after a hour" means that the t is 1.
The problem is asking for the population, which is P
Substitute t for 1 and you obtain:
P= 3000 x e^(1000 x 8 x 1)
P=3000e^8000

Let the sequence {an} be defined so that a1 = 1 and each succeeding term is found by adding 3 to the one before it. Find the for
atroni [7]

We are given

first term is 1

so, a_1=1

each succeeding term is found by adding 3 to the one before it

so, common difference is

d=3

Since, this is arithematic sequence

so, we can use nth terms formula

a_n=a_1+(n-1)d

now, we can plug values

and we get

a_n=1+(n-1)*3

a_n=1+3n-3

a_n=3n-2................Answer
