Answer:

The 80 p0und bag will last 128 days.

Step-by-step explanation:

In order to find out how much days the 80 pound bag last we have to divide the 80 pounds by the among that the dog eats each day. And so we get.....

80 / [tex]\frac{5}{8}[/tex] = [tex]\frac{80}{1} / \frac{5}{8}[/tex] = [tex](\frac{80}{1})(\frac{8}{5})[/tex] = [tex]\frac{640}{5}[/tex] = 128

Answer:

For some reason my answer got deleted.

The dog food will last 128 days,

Step-by-step explanation:

80 ÷ 5/8 = 128

Since 5/8 is being used each day, you divide.

Answer:

Personal observation.

Step-by-step explanation:

Worthy of note is to say that, it's is practically impossible to have a line of different people retell what they heard, saw or experienced in the same way. Because of the fact that human being differs, there's always a difference in the retelling of the story eventually. Everyone seems to retell the story in a manner they can relate to, in a manner of what they understand, and that's given rise to unreliability in personal observation. Not that they're wrong, nor that one is right than the other, but that they're just not reliable.

Answer:

5 seconds

Step-by-step explanation:

Looking at your function (h(t) = -16t^2 + 48t + 160), I see that the peak height will be 196 feet, and that is achieved in 1.5 seconds.

h(1.5) = -16(1.5)^2 + 48(1.5) + 160

h(1.5) = -16(2.25)+ 48(1.5) + 160

h(1.5) = -36 + 48(1.5) + 160

h(1.5) = -36 + 72 + 160

h(1.5) = 36 + 160

h(1.5) = 196

Going down from that height, it would take 3.5 more seconds, so it would take 5 seconds in total

h(5) = -16(5)^2 + 48(5) + 160

h(5) = -16(25) + 48(5) + 160

h(5) = -400 + 48(5) + 160

h(5) = -400 + 240 + 160

h(5) = -400 + 400

h(5) = 0

Answer:

1/3

Step-by-step explanation:

To make it shorter.

Answer:

$16.32

Step-by-step explanation:

First you need to find how much each thing is going to cost.

So for 32 glue sticks, it will cost $44.80 because you multiply 32 by 1.40.

Next you need to find the cost of thebox of crayons, which is $18.88 because you multiply 32 by 0.59.

Then you add those two totals together and you get 63.68.

Lastly you subtract that from 80 to see how much money Ms. Blankenship has  leftover which is $16.32.

Hope this helps. :)

Answer:

85.1 g

Step-by-step explanation:

Boris has 91.5 g of pepper

He used 0.4g to make one plate of scrambled egg

If she made 16 plates of scrambled egg then the amount of pepper that will be left can be calculated as follows

= 0.4×16

= 6.4g

= 91.5g - 6.4g

= 85.1g

Hence Boris will have 85.1g of pepper left

Answer:

x=3

y=8

Step-by-step explanation:

the given equations are y=3x-1 --------(1)

and y=2x+2---------(2)

Using substitution method,

and solving y=3x-1

y+1=3x

or y+1/3 =x ------(3)

Putting the value of x= y + 1 / 3 in equation 2

y= 2x+2

or, y = 2 ( y + 1/3) +2

or, y= 2y + 2 / 3 +2

or, y = 2y + 2 + 6 // 3 ( Taking LCM)

Or, 3 y = 2y + 2 + 6 ( the denominator gets multiplied to y)

OR, 3 Y - 2Y =6 PLUS 2

or y = 8

therefore, y=8

now substituting the value of y=8 in equation (3)

y + 1 /3 = x

or ,,, 8 plus 1 by 3 =x

or,,,,, 9 by 3 =x

Therefore, x is 3

318 de participanți

Explicație pas cu pas:

Dat fiind:

Număr în parc = 106

Numărul din parc reprezintă 1/3 din numărul elevilor care participă la activitatea de curățenie.

Pentru a obține numărul total de studenți care participă la activitate; fie numărul total = x

Prin urmare;

1/3 din x = 106

x / 3 = 106

Înmulțiți ambele părți cu 3

x = 318

Prin urmare, numărul total de studenți implicați în activitatea de curățenie = 318 stuaen

Answer:

6.25 or 6 1/4

Step-by-step explanation:

Jodie sold 6.25 candy altogether.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that perform the arithmetic operations are called arithmetic operators.

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

For example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

Given that

Jodie sells 2½ pounds of gumdrops,

3 pounds of orange slices, and ¾ pounds of gummi bears.

Convert the fractions into decimals

Number of pounds of gumdrops = 2½ = 5/2 = 2.5

Number of pounds of gummi bears = ¾ = 0.75

So the total amount of candy Jodie sold :

⇒ 2.5 + 3 + 0.75

⇒ 6.25

Hence, Jodie sold 6.25 candy altogether.

Answer:

15ft

Step-by-step explanation:

Calculation for how tall is the tree

First step Let the proportion be x/10ft = 6ft /4ft

Second step is to cross-multiply by 4x

4x =10ft*6ft

4x = 60

Third step is to divide both sides by 4

4x = 60

4x/4=60/4

x=15 ft

Therefore the tree will be 15ft tall

The expression in the form of a + ib is

-88 + 8i

where a = -88 and b = 8.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

2(-36 - 3i) + (5 + 2i)(12 - 2i)

Remove the parenthesis.

-72 - 6i + 60 - 10i + 24i + 4

Add like terms.

-88 + 8i

This is in the form of (a + ib).

Where a = -88 and b = 8

Thus,

-88 + 8i is our final expression.

The terms will be multiplied in order to get the simplified polynomials.

a. 6(x + 7)(x + 2)

[tex]6(x + 7)(x + 2)\\=6[x(x+2)+7(x+2)]\\=6(x^2+2x+7x+14)\\=6(x^2+9x+14)\\=6x^2+54x+84[/tex]
