In order to determine the slant height of several pyramids, Marjorie used the surface area formula, s= 1/2 pl+b for the slant he

m_a_m_a [10]

Answer:

$l=\dfrac{2(S-b)}{P}$

Step-by-step explanation:

The surface area formula for pyramids is given by :

$S=\dfrac{1}{2}Pl+b$ ...(1)

We need to arrange the formula for l.

Take b to LHS,

$S-b=\dfrac{1}{2}Pl\\\\2(S-b)=Pl\ [\text{cross-multiplying}]\\\\l=\dfrac{2(S-b)}{P}$

So, the expression is $\dfrac{2(S-b)}{P}$ for the slant height.

Can someone please help me??? And please be sure of ur answer :)

Rina8888 [55]

Answer:

1. is the last one.

2. is the 3rd one.

3. is the first one.

4. is the 2nd one.

Step-by-step explanation:

What you do is you have to get the letter by itself and it all depends on the less than or greater than signs.

For #1. -m+8>6. What you do is you minus 8 from both sides to get -m>-2. You still have a -m so you need to divide both sides by a -1. (one thing to remember is when you divide by a negative you have to switch the sign.) So your answer will be m<2. That will make the last graph the answer.

For #2. -2p< or equal to -10. What you do is divide by -2. and you need to remember to switch the sign. So your answer is p> or equal to 5.

You will do the same for the other two equations but your answers are.

#1. is the last one graph.

#2. is the 3rd one graph.

#3. is the first one graph.

#4. is the 2nd one graph.

Of the 6.25 billion people in the world, 310 million live in North America. What percent of the world's population lives in Nort

Talja [164]

Answer:

The percent of the world's population lives in North America is 5%.

Step-by-step explanation:

Given:

Of the 6.25 billion people in the world, 310 million live in North America.

Now, to find the percent of the world's population lives in North America.

Population of people in the world = 6.25 billion.

1 billion = 1000 million.

So, by using conversion factor we convert into million:

6.25 billion = 6250 million.

Population of people in North America = 310 million.

Now, to get the percent of the world's population lives in North America:

$\frac{310}{6250} \times 100$

$=0.0496\times 100$

$=4.96\%.$

So, the percent to the nearest whole number is 5%.

Therefore, the percent of the world's population lives in North America is 5%.
