three rock climbers started a climb with each person carrying 7.8 kilograms of climbing equipment. A fourth climber with no equipment joined the group The group divided the total weight of climbing equipment equally among the four climbers

Answers

Answer:

Each carried 1.95 kg weight

Step-by-step explanation:

Given :Three rock climbers started a climb with each person carrying 7.8 kilograms of climbing equipment.

A fourth climber with no equipment joined the group The group divided the total weight of climbing equipment equally among the four climbers

To Find : How much did each carry ?

Solution :

Each person out of three is carrying weight = 7.8 kg

So, Total weight carried by 3 climbers = $7.8 * 3 =23.4$

Now A fourth climber with no equipment joined the group

Total weight is divided among 4

So, weight carried by each climber = $(7.8)/(4)=1.95$

Hence each carried 1.95 kg weight

The correct answer is:

Each climber is carrying 5.85 kg.

Explanation:

3 of the 4 climbers is carrying 7.8 kg each; this is 3(7.8) = 23.4 kg.

Dividing this equally among the 4 climbers, we have 23.4/4 = 5.85 kg each.

Find the value of x.

pls help! tysm

Answers

Answer:

x = 30.

Step-by-step explanation:

The angle next to the 60 degree angle = 180 - 60 = 120 degrees (adjacent angles are supplementary).

Let the angle just above 3x be y. The sum of 3x and y = 120 degrees (as opposite angles of a parallelogram are equal).

We have the following equations.

3x + y = 120............(1)

2x + 90 + y = 180

2x + y = 90.............(2)

Subtracting, (1) - (2):

x = 30.

Kit gathered 5 eggs when she visited her cousin's farm. Altogether, the eggs weighed 225.0 grams. She wrote down the weight of each egg, but missed the last egg. The 4 weights she recorded were 45.07 grams, 45.72 grams, 43.98 grams, and 45.02 grams. Find the weight of the missing egg. Then, to help her uncle figure out which chickens are producing the best eggs, help her order the egg weights from least to greatest. How did place value help you compare and contrast the numbers in problem 5?

Answers

add up all the numbers you have, once you get the answer to that. subtract it from 225.0 then youll have the weight of the missing egg. And you will be able to put the eggs least to greatest

The total weight of 6 pieces of butter and a bag of sugar is 3.8lb. If the weight of the bag of sugar is 1.4 lbs what is the weight of each piece of butter

Answers

the total weight of 6 pieces of butter and bag of sugar is 3.8 lb

lets name a piece of butter as x

there are 6 pieces of butter - then x * 6 = 6x

if we write an equation for the total cost

6x + bag of sugar = 3.8 lb

weight of bag of sugar = 1.4 lb

6x + 1.4 lb = 3.8 lb

6x = 3.8 - 1.4

6x = 2.4 lb

x = 2.4/6

x = 0.4 lbs

therefore weight of a piece of butter is 0.4 lbs

The weight of each piece of butter is $\boxed{\bf0.4{\text{ lbs}}}$ .

Further explanation:

Given:

The total weight of 6 pieces of butter and the weight of a bag of sugar is equal to 3.8 lbs.

The weight of the bag of sugar is 1.4 lbs.

Our aim is to find the weight of each piece of butter.

Calculation:

Let the weight of each piece of butter to be $x$ lbs.

Also consider the weight of a bag of sugar to be $y$ lbs.

Then the weight of 6 pieces of butter is $\boxed{6x}$ .

Therefore, the total weight of 6 pieces of butter and one bag of sugar is calculated as.

${\text{Total weight}}=6x+y$

Given that total weight of 6 pieces of butter and one bag of sugar is equal to 3.8.

Now, the total weight in the form of an equation can be written as,

$6x+y=3.8$ ……(1)

Since, the weight of one bag of sugar is equal to 1.4 lbs., then substitute 1.4 for $y$ in equation (1) to obtain the value of $x$ as follows:

$6x+1.4=3.8$

Subtract 1.4 on both sides of above equation as follows:

$\begin{aligned}6x+1.4-1.4&=3.8-1.4\n6x&=2.4\n\end{aligned}$

Now, divide both sides of above equation by 6 to obtain the value of $x$ as follows:

$\begin{aligned}\frac{{6x}}{6}&=\frac{{2.4}}{6}\nx&=0.4\n\end{aligned}$

Therefore, the weight of each piece of butter is equal to $\boxed{\bf0.4{\text{ lbs}}}$ .
