Answer:

none

Step-by-step explanation:

the man is carrying 3 sacks

each has 30 coconuts

so at total he has 90 coconuts:  30*3= 90  

he passe through 30 checkpoints

ha has to give 1 coconut for each sack

so he gives 3 coconuts each time: 3*1=3

there are 30 ckeckpoints so : 3*30= 90

he has spent all the coconuts unless he has a trick

He starts with 3 sacks with 30 in each sack.

He has to give 1 coconut per sack away. So at first he gives 3 coconuts away.

The first 10 checkpoints he gives away 30 coconuts, so he is left with 2 sacks.

Now he has to give 2 coconuts away. 30/2 = 15, so the next 15 checkpoints he ends up giving away another full sack, so he is left with 1 full sack of 30 coconuts and he has 5 checkpoints left.

Giving away 1 coconut at those checkpoints, he would have 25 left

Answer:

$-9125

Step-by-step explanation:

6.25÷100 = 0.0625                                    50×12=600

0.0625×250= $15.625

6.25%=$15.625

15.625×600= $9375

$250-$9375=  -9125

The account be worth at the end of the 50-year period will be 9125 dollar.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that savings account is opened with an initial deposit of $250, and interest is compounded monthly at 6.25% for 50 years.

The rate is 6.25÷100 = 0.0625                                    

Therefore, 50×12=600

0.0625×250= $15.625

Since we know that 6.25%=$15.625

15.625×600= $9375

Thus we get;

$250-$9375 = -9125

Hence, the account be worth at the end of the 50-year period will be 9125 dollar.

→Answer:

3.2 liters of lemonade were consumed during the party.

→Step-by-step explanation:

What we know

_____________________________________

Well there is 2,500 mL of strawberry lemonade

There are  2 liters of cherry

There are 5 deciliters of dog limeade

_____________________________________

So the 5 deciliters of dog limeade doesn't count because it is limeade, not lemonade.

The question is asking for the number of liters so we need to convert the 2,500 milliliters of lemonade to liters.

Which will be 2.5 liters of lemonade.

There are also 2 liters of cherry lemonade so 2.5 + 2 is 4.5.

So if 1.3 liters were left over doing 4.5 - 1.3 we get 3.2, meaning 3.2 liters of lemonade were consumed during the party.

Answer:

5.8 * 10^26 kg

Step-by-step explanation:

If the mass of the earth is 1/95 of that if saturn, this means that the mass of saturn is 95 times that of earth

From the question we were given the mass of the earth as 5.97 * 10^24

The mass of saturn is thus 95 * 5.97 * 10^24 =

576.15 * 10^24

This is 5.8 * 10^26 kg

Step-by-step explanation:

The points that you start off with are L(-4,6), M(-1,6), N(-1,2), and O(-4,2), and when you reflect the rectangle across the y-axis, you will have (4,6), (1,6), (1,2), and (4,2). Now you can translate your rectangle down four and once to the left, which will give you L''(3,2), M''(0,2), N''(0,-2), O''(3,-2).

Answer:

5 units in the positive y-axis

Step-by-step explanation:

In order to get triangle D’E’H’, triangle DEH was moved upwards for a number of units which can be obtained by taking a corner of the rectangle and counting the number of square spaces (grids) it was moved upwards by.

Step one: Pick a corner of the triangle.

For this, we can pick corner D and note its position on the graph

Step two: Count the number of squares between point D and D'.

Once we count this, we can see that there are 5 square spaces between D and D'.

Step Three: Repeat the process for the other two corners of the rectangle.

If the square spaces counted  are the same with what was obtained for the first corner, we can comfortably say that the rectangle was translated upwards by a distance of 5 units

The inverse of function is x= √1/3( y+5 )

A function that reverses the effects of another function is called an inverse function. When y=f(x) and x=g(y), a function g is the inverse of a function f. . Applying f and then g is equivalent to doing nothing, in other words. This can be expressed as g(f(x))=x in terms of the relationship between f and g.

Given:

g(x) = 3x² - 5

To find the inverse of the function take g(x) = y

Then, solve for x

y=  3x² - 5

y + 5=  3x²

x² = 1/3( y+5 )

x= √1/3( y+5 )

Hence, the inverse of function is x= √1/3( y+5 ).

Answer:

10/16 but I’m pretty sure your teacher is gonna want for you to reduce to where you answer would actually be 5/8

Step-by-step explanation:

1/16 +9/16 you’ll add the top number which equals up to 10, but since both of your bottom number are the same you lol keep those making your answer 10/16. But most teacher prefer you to reduce so it’ll bring your answer to 5/8 since the only number that can go into both 10 and 16 is 2 which is what you did. In conclusion 5/8 is your answer.

We can calculate this using circle theorems

The correct circle theorem to use here is that angle at center is 2 times angle at circumference

The angle we want to calculate here is the angle at circumference but we were given the angle at the center

So the value of the angle at the circumference would be 108/2 = 54

The volume of the rectangular pyramid is 80 cubic centimeter.

Volume is the measure of the capacity that an object holds.

[tex]v = \frac{lwh}{3}[/tex]

Where,

V is the volume of the  rectangular pyramid

l is the base length

w is the base width

h is the Pyramid height

According to the given question

We have

Base length of the rectangular pyramid = 8cm

Base width of the rectangular pyramid = 6cm

And the height of the rectangular pyramid  = 5cm

Therefore,

The volume of the rectangular pyramid is given by

V = [tex]\frac{(8)(6)(5)}{3}[/tex]

⇒ V = 8 × 2 × 5

⇒ V = 30 cubic centimeter

Hence, the volume of the rectangular pyramid is 80 cubic centimeter.

Step-by-step explanation:

Since 3 sides are congruent to 3 other sides, the two triangles are congruent due to the SSS postulate.

SSS stands for "side side side". It means that if you have three pairs of congruent corresponding sides, then the triangles are congruent. It's like saying every corresponding piece of two houses are the same, so the two houses overall must be identical.

Answer:

x = - 3, x = 0.5

Step-by-step explanation:

Given

10x² + 5x - 15 = - 12 + 8x² ( subtract 8x² from both sides )

2x² + 5x - 15 = - 12 ( add 12 to both sides )

2x² + 5x - 3 = 0 ← in standard form

(x + 3)(2x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = 0.5
