182.
48x4= 192 (closest to 182) since you can’t have a remainder of kids.
(I’m in 6th grade so I hope I helped and didn’t get it wrong)

Lucy has block letters that are in the shape of cubes with sides 2 3 foot long. She has a box which is 1 1 3 foot long, 2 3 foot wide, and 2 3 foot tall.
Complete question :
Lucy has block letters that are in the shape of cubes with sides 2 3 foot long. She has a box which is 1 1 3 foot long, 2 3 foot wide, and 2 3 foot tall. Find the number of block letters that will fit in the box.
Answer:
1/2
Step-by-step explanation:
Number of block letters that will fit in :
Volume of box ÷ volume of each letter cube
Volume of each letter cube = (side length)³ = (2/3)³ = 8/27 ft³
Volume of box = length * width * height
Volume of box = 1 1/3 * 2/3 * 2/3
Volume of box = 4/3 * 2/3 * 2/3 = 16 / 27 ft³
Therefore ;
8/27 ÷ 16/27
8/27 * 27/16
= 8/16
= 1/2

9514 1404 393
Answer:
x ≈ 136.7 ft
Step-by-step explanation:
As you have marked, the relevant sides are the adjacent side and the hypotenuse. The mnemonic SOH CAH TOA reminds you ...
Cos = Adjacent/Hypotenuse
For this triangle, that means ...
cos(43°) = (100 ft)/x
x = (100 ft)/cos(43°) . . . . . . . . . . multiply both sides by x/cos(43°)
x ≈ 136.73 ft
The length x is about 136.7 feet.

Find the Cartesian equation of the curve with parametric equations x = 2 sec(t) and y = 3 tan(t) for t ∈ π/2 , 3π/2, and describe the curve.
Answer:
4y^2 - 9x^2 = -36
Step-by-step explanation:
x = 2 sec t
y = 3 tan t
x^2 = 4 sec^2 t
y^2 = 9 tan^2 t
Now sec^2t = 1 + tan^2 t so we have:
4(1 + tan^2 t) + 9 tan^2 t = x^2 + y^2
4 + 13 tan^2 t = x^2 + y^2
13 tan^2 t = x^2 + y^2/ - 4
tan^2 t = x^2/13 + y^2/13 - 4/13
But , from the second equation tan t = y/3 so tan^2 t = y^2/9, so:
y^2/9 = x^2/13 + y^2/13 - 4/13
LCM of 9 and 13 is 117 so multiply thru by 117:
13y^2 = 9y^2 + 9x^2- 36
4y^2 - 9x^2 = -36

3. Jaselle earned $80.00 raking leaves. This is 8 dollars more than 4 times the amount that Dillon
earned. How much did Dillon earn?
(25 Points)
Answer:
Step-by-step explanation:
So, Jaselle has $80.00.
This is 8 dollars more than 4 times the amount that Dillon
earned.
$80.00 - 8.00 = $72.00
4 Times average amount = $72.00
Average (begining amount) = $18.00

Olivia has a 20 meter-long fence that she plans to use to enclose a rectangular garden of width w. The fencing will be placed around all four sides of the garden so that its area is 18.75 square meters. Write an equation in terms of w that models that situation.
Answer:
Step-by-step explanation:
Length of garden = 10-w
Area = (10-w)w = 18.75
w² - 10w + 18.75 = 0
Answer is [tex]w^{2} - 10w + 18.75 = 0[/tex]
Rectangle Formulas:
Area of the Rectangle (A) = length x breadth.
Perimeter of rectangle (P) = 2 x (length + breadth)
(Given),
A = 18.75square meters
P = 20 meter
Let's length be l and width be w.
P = 2 (l + w)
20 = 2(l + w)
l + w = 10
l = 10 - w ----( 1 )
Now, A = l x w
18.75 = (10 - w) x w
18.75 = 10w - [tex]w^{2}[/tex]
[tex]w^{2} - 10w + 18.75 = 0[/tex]
