How many pairs of whole numbers have a sum of 110

1 answer:

3 0

Whole numbers include 0, 1, 2, 3, 4, 5, and so forth.
There are 56 pairs of whole numbers that add up to 110, such as:
0 + 110 = 110
1 + 109 = 110
2 + 108 = 110
.
.
.
.
.
55 + 55 = 110
Thus, the total count of pairs is 56.

7. During a person's commute to school, she spends 10 minutes driving 30 miles per hour (mph) and 5 minutes stopped at red light

Inessa [12570]

Answer:

5 miles in total

Step-by-step explanation:

Given:

Time spent driving = 10 min = 10 / 60 = 1/6 hour

Duration of stop = 5 min

Driving speed = 30 miles per hour

Find:

Complete distance

Computation:

Distance traveled = Speed × time

Distance = 30 × (1/6)

Total distance = 5 miles

Which are the roots of the quadratic function f(b) = b2 – 75? Select two options. b = 5 StartRoot 3 EndRoot b = Negative 5 Start

zzz [12365]

Answer:

b = 5√3

b = -5√3

Step-by-step explanation:

We have

$f(b)=b^{2}-75$

Keep in mind, the root of a function corresponds to the value of x at which the function's output is zero.

In this case

The roots of the equation are the b values for which f(b) equals zero.

Thus

For f(b)=0

$b^{2}-75=0$

$b^{2}=75$

Take the square root of both sides

$b=(+/-)\sqrt{75}$

Now simplify

$b=(+/-)5\sqrt{3}$

$b=5\sqrt{3}$ and $b=-5\sqrt{3}$

So we find that

b = 5√3

b = -5√3

Biologists stocked a lake with 240 fish and estimated the carrying capacity (the maximal population for the fish of that species

Inessa [12570]

Answer:

2.30 years

Step-by-step explanation:

The fish population increased threefold in the first year, resulting in 240 * 3 = 720 fish.

(a) The logistic equation can be represented as follows

$P = P_0e^{kt}$

where P0 = 240 denotes the initial fish count; substituting P = 720 and t = 1 allows us to determine the constant k

$720 = 240e^{1k}$

$e^k = 3$

$k = ln3 = 1.1$

b) By applying the formula below

$P = P_0e^{kt}$

with P set to 3000, P0 as 240, and k equal to 1.1, we can compute the duration needed for the population to reach 3000 fish

$3000 = 240e^{1.1t}$

$12.5 = e^{1.1t}$

$1.1t = ln12.5 = 2.53$

$t = 2.30 years$
