Rzqust [24]

Answer:

After 46 years, the population of this country will be doubled.

Step-by-step explanation:

Given that,

The population of a certain country is growing rate 1.5%.

The formula for this is

t=\frac{ln2}{k}

t= time in years

k=population growth rate.

Here k=1.5% =\frac{1.5}{100} = 0.015

t=\frac{ln2}{0.015}

  ≈46 years

After 46 years, the population of this country will be doubled.

Having trouble with problems like these.
V125BC [204]

A: A is not correct. The two angles mentioned are interior and supplementary. They do not share a common vertex.

B: The two angles that share a common vertex (and are supplementary) are <JKN and <LKN So far this is the answer.

C: <MNP and <JKN are equal so they cannot be adjacent angles. Not when the transversal is on an angle like this.

D: <ONK and <JKN can be shown to be supplementary, but they have no special name. As a result, these two cannot be the answer

If x + y = 2 and x - y = 6, solve for x and y.
anyanavicka [17]

Answer:

Step-by-step explanation:

Givens

x + y = 2

x - y = 6

Solution

Just add the two equations together. The y's will drop out.

x + y = 2

<u>x - y = 6 </u>             Add

2x = 8                 Divide by 2

2x/2 = 8/2          Combine

x = 4                   Substitute x = 4 into the top equation

x + y = 2

4 + y = 2             Subtract 4 from both sides

4-4+y=2-4          Combine

y = - 2    

Answer

x = 4

y = -2

The surface area of a rectangular prism is 2210 cm2. Two of the dimensions are 5 cm and 10 cm. Find the measure of the other dim
Vlad [161]

The surface area of a rectangular prism is 2210 cm^2 Then the other dimension is 70.3 cm

<h3><u>Solution:</u></h3>

Given that surface area of rectangular prism is 2210 square centimeter

Also given that two of dimensions are 5 cm and 10 cm

To find: other dimension

<em><u>The total surface area of the rectangular prism is gievn as:</u></em>

\text {Total surface area }=2(lb+b h+h l)

Where, "l" is the length and "b" is the breadth and "h" is the height

The given values are:  l = 5cm and b = 10cm

On substituting the given values in formula we get,

\begin{array}{l}{2210=2(l \times b+b \times h+h \times l)} \\\\ {2210=2(5 \times 10+10 \times h+h \times 5)} \\\\ {2210=2(50+10 h+5 h)} \\\\ {1105=50+15 h} \\\\ {1055=15 h} \\\\ {h=70.3}\end{array}

Thus the other dimension is 70.3 cm
