The number of bags of sand needed to fill the sandbox is 18 bags

Volume = L × W × H

= 4 1/2 × 4 × 1/2

= 4.5 × 4 × 0.5

= 9 ft³

Number of bags of sand needed to fill the sandbox = volume of the sandbox ÷ quantity of each bag

= 9 ft³ ÷ 1/2 fr³

= 9 × 2/1

= 18 bags

The two negatives cancel out when we divide or multiply. Think of negative as opposite. Having two opposites cancel.

The slash means fraction and it also means division

6/7 = 6 divided by 7

6/7 = six sevenths

So that allows us to go from fraction to decimal form 6/7 = 0.857 approximately after using your calculator or long division.

Answer:

33

Step-by-step explanation:

The bottom angle is a completely straight line, and that means the angle is 180 degrees.

180 - 81 = 99

So, this means 3x = 99. We need to isolate the variable, so we have to divide everything by 3.

x = 33

Answer:

waaait i know how to do this lol ( i feel like this is correct)

x = 33

Step-by-step explanation:

so a line is 180 right?

so make the equation like this

180 = 81 + 3x

now solve for x by doing algebra

(minus both sides by 81)

3x = 99

x = 33

The balance after 5 year comes out to be $3552.80

Compound interest is the interest on savings that is computed using both the original principal and the interest accrued over time. It will accelerate the growth of a sum more quickly than simple interest, which is only applied to the principal sum.

Here,

The declan deposits $850 into a savings account that pays 3.4% annual interest compounded quarterly.

Thus rate= 3.4% and principle amount = 850

Therefore it is compounded quartely,

The balance after year=

[tex]C=Pe^{rt}[/tex]

[tex]C= 850 e^{3.5(5)}\\\\C= 850 e^{17.5}[/tex]

C = 3552.80

Therefore, the balance after a year comes out to be $3552.80

Therefore the balance comes out to be after compounded annually is

$3552.50

Answer:

The minimum number of fish each must have caught is 90 fishes

Step-by-step explanation:

The number of fishes Tisha's net can hold = 15

The number of fishes Dana's net can hold = 18

Let the total number of fishes both Tisha and Dana caught = X

15 × A = 18 × B = X

Therefore, X is the lowest common multiple (LCM) of 15 and 18 given as follows;

15 = 3 × 5

18 = 3 × 6

Therefore, the LCM of 18 and 5 = 3 × 5 × 6 = 90

Which gives, the minimum number of fish each must have caught = 90 fishes.

Coordinates of point D of parallelogram = (3 , -4)

A parallelogram is quadrilateral in which opposite angles are equal and opposite sides of the quadrilateral are equal and parallel to each other.

The Diagonals in the parallelogram bisect each other.

Given points

A(-4,-6), B(-10, -10), C(-3, -8)

Let the 4th point D = (x , y)

In a parallelogram, diagonals bisect each other.

midpoint of BD = midpoint of AC

If two points are (x₁ , y₁) and (x₂,y₂)

then midpoint = {(x₁+x₂)/2 , (y₁+y₂)/2}

midpoint of AC = {(-4 + -3)/2 , (-6 + -8)/2}

                         = {-7/2 , -7}

midpoint of BD = {(-10 + x)/2 , (-10 + y)/2}

Now,

midpoint of BD = midpoint of AC

{-7/2 , -7} =  {(-10 + x)/2 , (-10 + y)/2}

Comparing both sides

taking x -coordinate

(-10 + x)/2 = -7/2

Multiplying with 2 on both sides

-10 + x = -7

x = 3

taking y -coordinate

(-10 + y)/2 = -7

Multiplying with 2 on both sides

-10 + y = -14

y = -14 + 10

y = -4

Point D (x , y) = (3, -4)

Hence, (3, -4) are the coordinates of point D of parallelogram.

The number that needs tο be added tο cοmplete the square is 90.25.

In algebra, a quadratic equatiοn is any equatiοn that can be rearranged in standard fοrm as where x represents an unknοwn value, and a, b, and c represent knοwn numbers

Tο cοmplete the square fοr the quadratic equatiοn x² - 19x + 23 = 0, we need tο add a number that is equal tο half οf the cοefficient οf x (which is -19) squared.

Sο,

(-19/2)² = 90.25

Therefοre, we need tο add 90.25 tο bοth sides οf the equatiοn:

[tex]x^2 - 19x + 23 + 90.25 = 90.25[/tex]

Then we can rewrite the left side as a perfect square:

[tex](x - 9.5)^2 = 90.25[/tex]

Now we can take the square root of both sides to solve for x:

x - 9.5 = ±√(90.25)

x = 9.5 ± 9.5√(2)

Hence, the number that needs to be added to complete the square is 90.25.
