Andy works at a grocery store. The manager of the store would like Andy to set up a display of apples. Part of the display will include bags of apples. If there are 39 pounds of apples in the back of the store, how many bags of apples can Andy make for the display? each bag has 1 1/2 pound

Answers

Answer:

Andy can make 26 bags for the display.

Step-by-step explanation:

Quantity of apples in the back of the store = 39 pounds

Quantity of apples in one bag = [tex]1\frac{1}{2}[/tex] pounds

Here,

[tex]1\frac{1}{2}=\frac{2(1)+1}{2}=\frac{3}{2}[/tex]

Number of bags = Quantity of apples in the back of the store / Quantity of apples in one bag

[tex]=\frac{39}{1\frac{1}{2} }=\frac{39}{\frac{3}{2} }=39(\frac{2}{3})=26[/tex]

So, Andy can make 26 bags for the display of apples.

The pool is 400 square meters

Step-by-step explanation:

To figure out the are of a slanted shape such as this, we must turn it into a shape that is non-slanted, like a rectangle or square (which is a type of rectangle). For this parallelogram, we can separate the shape into three parts: the two slanted bits on the outside, and a rectangle (7*2) in the middle (or on the inside).

We can see that each slanted part can take up half of two squares, and therefore one square. From here on out, we can do this one of two ways:

1. Figure out the area of the inside rectangle, then add the two slanted parts/two squares separately

OR

2. Since each slanted area equals one square, or since each is half of two square, we can add both sides together (for 1/2 + 1/2 = 1, or in this case,        1 +1 = 2), to make a full or complete rectangle, before figuring out the area of the shape as a whole (8*2).

8*2 = 16

Each square is 1 cm squared, which is in proportion to 25 meters squared (each cm is 5 meters (1:5), so the square, which is 1 cm by 1 cm, is proportionate to 5 meters by 5 meters).

16*25 = 400

The pool is therefore 400 square meters.

a projectile is thrown upwards from an initial height of 1584 feet so that it's distance above the ground after t seconds is modeled by the given function.
h(t)=-16t^2+480t+1584.

what is the maximum height it will reach?​

Answers

Answer:

5184 ft

Step-by-step explanation:

Given

A quadratic function

h(t)= -16t^2+480t+1584.

Its maximum is its vertex

Vertex formula for ax^2 + bx + c is

x = -b/2a

Applying this to our function

t = -480/2(-16) = 15

Maximum height is reached after 15 seconds and is

h(15) = -16*15^2 + 480*15 + 1584 = 5184 ft

Three friends entered a race around a track. Edward takes 6 minutes to run one lap. Bernie takes 3 minutes to run one lap and it takes Freddie 5 minutes to run one lap. If all three friends begin the race at the same time, how many minutes will it take for all three friends to be at the starting point again?

Answers

Answer:

It will take 30 minutes

Step-by-step explanation:

Here, we want to calculate the time it will take for the three friends to be at the starting point again

What we do here is to note the time it will take for each of the three friends to run a lap

That will be 6 , 3 and 5

What we now need to know the time is to find the lowest common multiple of the three amount of time

The lowest common multiple of 6,3 and 5 is 30

So the amount of time it will take the friends to be at the starting point again is 30 minutes

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Joel used a half gallon of paint to cover 84 square feet of wall.

Then in one gallon of paint he can cover 168 square feet.

He has 932 square feet of walls of paint.

Then the number of the gallon of paint is need will be

⇒ 932 / 168

Answer:

Possible rational roots: ±1,±5.

Actual rational roots: −1,5.

Step-by-step explanation:

The trailing coefficient (coefficient of the constant term) is −5.

Find its factors (with plus and minus): ±1,±5. These are the possible values for p.

The leading coefficient (coefficient of the term with the highest degree) is 1.

Find its factors (with plus and minus): ±1. These are the possible values for q.

Find all possible values of pq: ±11,±51.

Simplify and remove duplicates (if any), these are possible rational roots: ±1,±5.

Next, check the possible roots: if a is a root of the polynomial P(x), the remainder from the division of P(x) by x−a should equal 0.

Check 1: divide x3−3x2−9x−5 by x−1.The quotient is x2−2x−11 and the remainder is −16  

Check −1: divide x3−3x2−9x−5 by x+1.The quotient is x2−4x−5 and the remainder is 0  

So, −1 is a root.

Check 5: divide x3−3x2−9x−5 by x−5.The quotient is x2+2x+1 and the remainder is 0  

So, 5 is a root.

Check −5: divide x3−3x2−9x−5 by x+5.The quotient is x2−8x+31 and the remainder is −160  

1. Find all of the possible roots by using ±p/±q p= the constant
q= lead coefficient of highest term which is x^3 which has a leading coefficient of 1.
2. P=±1,±5, Q=±1. You would divide the factors of the constant by the factors of the leading coefficient.
3. Possible roots for this equation. ±1,±5.
4. Factor the equation.

x³-3x²−9x−5

x³+x²−4x²−4x-5x-5

x²(x+1)-4x(x+1)-5(x+1)

(x+1)(x²-4x-5)

(x+1)(x-5)(x+1)

5. Set all of the factors to zero and solve for x to get your rational roots to the equation.

x+1-1=0-1
x=-1

x+1-1=0-1
x=-1

x-5+5=0+5
x=5

6. Final Solution:

Possible Rational Roots: ±1, ±5

Given is that the value of a house is $655,000 in cash, but when selling it on installments, you are charged 25.5% of its price.

 

Assume the price when selling on installments be $x. Then, we can write new price as -

[x] = 655000 + {25.5% of 655000}

[x] = 655000 + {25.5/100 x 655000}

[x] = 655000 + {25.5 x 6550}
[x] = 655000 + 167025

[x] = $822025

Therefore, the price when selling on installments be $822025.
