A baby elephant named Nora was born at a wildlife refuge and weighed 200 lbs when she was
born and gained 22 lbs every week. In preparation for her birth, the staff estimated how much
she would weigh at certain weeks so they could stock some of her food ahead of time. They
documented that at 16 weeks she would weigh approximately 352 lbs. Did they estimate
correctly? If so, explain why. If not, describe what they did wrong and find her accurate weight.​

Answers

Answer:

352 lbs is correct

Step-by-step explanation:

They did estimate correctly. for how to do this look below:

So we have a elephant that gains 22 pounds every week and they estimated that at 16 week she would be at 352 lbs

22 which was current pounds at the time and she would keep gaining that every week for 16 weeks

So weight times weeks

22*16

22*16= 352

Question 8

A science club rents a bus for a trip to a state park. The bus rental is
$350, and admission to the park is $8 per person. The cost of the bus
rental will be shared equally. Write an expression that can be used to
determine the cost of the trip for each club member.

Answers

8x + 350
This is because each person has to pay 8 dollars and everyone combined has to pay 350 for the bus rental

Let m be the number of club members.

Since they will share the $350 cost of the bus equally, then each member pays 350/m dollars for their share of the bus cost.

The admission is $8 per person, so the total cost per person is;

[tex]\frac{350}{m} +8[/tex]

Find the distance between points (1, 5) and (3, 0) to the nearest tenth. !!

Answers

Answer:

The answer is

Answers

Answer:

Step-by-step explanation:

5,762 - (-8)

The total difference between the highest point and the lowest point of the country is given as 5, 770 feet.

Given that,
At its highest point, the elevation of a country is 5,762 feet above sea level. At its lowest point, the elevation of the country is 8 feet below sea level.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Highest point = 5,762
The lowest point below the sea level = -8 feet
Total difference in the point = 5762 - (-8) = 5770 feet

Thus, the total difference between the highest point and the lowest point of the country is given as 5, 770 feet.

Janel can make total of 12 bracelets.

DivisionWhat is division?

One of the four fundamental operations, along with addition, subtraction, and multiplication, is division. A number is split in the straightforward action of division.

Relation of dividend, divisor, quotient and remainder:

The following dividend formula can be used to find the dividend if the values of the divisor, quotient, and remainder are provided.

Dividend = Divisor x Quotient + Remainder

Calculation for the number of bracelets:

Janel has total number of beads = 600.

Beads required to make one bracelet = 48.

To calculate the number of beads divide total number of beads by 48.

Beads = 600/48

Quotient comes out as 12 and remained comes out as 24.

Therefore, the total number of bracelets can made is 12.

After completion of 12 bracelets 24 beads will left.

a(t+z)=45z+67

Step 1: Add -45z to both sides.

at+az+−45z=45z+67+−45z

at+az−45z=67

Step 2: Add -at to both sides.

at+az−45z+−at=67+−at

az−45z=−at+67
