Answer:
[tex]Volume = \: length \times width \times hight[/tex]
[tex]10 \times 1000 = \: 40cm \times 25cm \times hight[/tex]
[tex]Hight = \frac{10000}{40cm \times 25cm} [/tex]
[tex]Hight = 10cm[/tex]
The height of the container is 10 cm.
Given that, 10 liters of oil is poured into a container whose cross section is a rectangle with dimensions 40 cm ×25cm.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
We know that, 1 liter = 1000 cm³
So, 10 liters = 10000 cm³
Area of the base = 40 × 25 = 1000 cm²
Volume = 1000 × Height
⇒ 1000 × Height=10000
⇒ Height=10 cm
Therefore, the height of the container is 10 cm.

Maria used some fabric to make 3 skirts, She used 3/10 to make the first one, 5/10 to make the second one. How much fabric did she used to make the third one?*
Answer:
2/10
Step-by-step explanation:
1 whole is equal to 10/10
5/10+3/10=8/10
10/10-8/10=2/10
hope this helps! :)
Answer:
the full lenght of fabric is 10/10 so if she used 3/10 and 5/10 that's in total 8/10.. she used 2/10 for the third skirt

The scale of a map is 1:3,000,000. What is the actual distance in km corresponding to 12 cm on the map?
3600 km
360 km
36 km
3.6 km
Answer:
Step-by-step explanation:
The scale number can be interpreted as (1cm/3,000,000 km), a conversion factor. Since it is a conversion factor, we can invert it to the form:
(3,000,000 km/1cm)
A measure of 12cm on the map would correspond to:
(12cm)*((3,000,000 km/1cm) = 42,000,000 km
Wow - a long trek, if you need water.
Note that inverting the conversion factor isn't totally necessary, since we could use the original form and divide:
12 cm/(1cm/(3,000,000km)) = 42,000,000 km
But I dislike division, so I always invert a conversion factor if it makes the calculation more convenient, for me.

15x+10y=8xy+28x find an expression for y in terms of x
Answer:
y = [tex]\frac{13x}{10-8x}[/tex]
Step-by-step explanation:
15x + 10y = 8xy + 28x ( subtract 15x from both sides )
10y = 8xy + 13x ( subtract 8xy from both sides )
10y - 8xy = 13x ← factor out y from each term on the left side
y(10 - 8x) = 13x ← divide both sides by (10 - 8x)
y = [tex]\frac{13x}{10-8x}[/tex]
Answer:
y = 13x/10-8x
Step-by-step explanation:
15x + 10y = 8xy + 28x
10y = 8xy + 13x
10y - 8xy = 13x
y(10 - 8x) = 13x
y = 13x/10-8x

Trigonometry, due in a few hours, 100 pts
Answer:
a) 120°
b) 16√3 ≈ 27.7 cm²
Step-by-step explanation:
a)Each exterior angle of a regular polygon measures 360° divided by the number of sides. For a hexagon, the exterior angle is 360°/6 = 60°. That means the adjacent interior angle is 180°-60° = 120°.
Angle ABC measures 120°.
__
b)The area of triangle ABC can be found using the formula ...
A = 1/2ab·sin(C) . . . . area of triangle with sides a, b, and angle C between them
A = 1/2(8 cm)(8 cm)sin(120°) = (32 cm²)(√3/2) = 16√3 cm²
The area of the triangle is 16√3 cm² ≈ 27.7 cm².
Answer:
∠ABC = 120°
ΔABC = 16√3 cm²
Step-by-step explanation:
Part (a)
Sum of interior angles of a regular polygon = (n - 2) × 180°
(where n is the number of sides)
⇒ Sum of interior angles of a regular hexagon = (6 - 2) × 180° = 720°
All the interior angles in a regular polygon are equal.
⇒ Interior angle = sum of interior angles ÷ number of sides
⇒ ∠ABC = 720° ÷ 6
⇒ ∠ABC = 120°
------------------------------------------------------------------------
Part (b)
Use the sine rule for area of a triangle:
[tex]\dfrac12ab \sin(C)[/tex]
(where a and b are the sides and C is the included angle)
Given:
a = 8b = 8C = ∠ABC = 120°Substituting values into the formula:
[tex]\implies \dfrac12\cdot 8 \cdot 8 \sin(120)=16\sqrt{3} \ \sf cm^2[/tex]
Kim had $472.15 in her checking account.
She deposited $188.50 and wrote a check
for $263.89. How much is in Kim's checking
account now?
Answer:
Kim's checking account has $396.76 left.
Step-by-step explanation:
Kim had $472.15 in her checking account. She deposited $188.50 and wrote a check for $263.89. How much is in Kim's checking account now?
The equation tells us that Kim added 188.5 to the original 472.15 in her checking account. 472.15 + 188.5 = 660.65But then the equation also says she took out, or wrote a check, for 263.89. 660.65 - 263.89 = 396. 76 This means that kim's checking account has $396.76 left.What is the vertical distance from the orgin to the point (6,3)

Which is the destructive interference formula for diffraction grating problems? dsin = dcos = dcos = n dsin = n
The destructive interference formula for diffraction grating problems is [tex]d\ sin(\theta) = (n+\dfrac{1}{2} )\lambda[/tex].
What is destructive interference?When the maxima of two waves are 180 degrees out of phase, destructive interference occurs: a positive displacement of one wave is cancelled exactly by a negative displacement of the other wave. The resultant wave has zero amplitude.
In a diffraction grating, the formula for brighter patches arising from constructive interference and darker patches arising from destructive interference is:
[tex]d\ sin(\theta) = n\lambda[/tex]
Here, d is the grating spacing, θ is the angle of light, n represents the fringe order, and w denotes the wavelength.
The value of N can only be integers values.
Now, Because destructive interference occurs between the fringes, the destructive interference formula is
[tex]d\ sin(\theta) = (n+\dfrac{1}{2} )\lambda[/tex]
where n is again an integer.
Hence, the destructive interference formula for diffraction grating problems is [tex]d\ sin(\theta) = (n+\dfrac{1}{2} )\lambda[/tex].

The cheerleaders from Newberg High School are doing a giftwrapping fundraiser at a clothing

total of 468 feet of wrapping paper. The day before, they wrapped 28 small clothing boxes
and 39 large clothing boxes, using a total of 480 feet of gift wrap. How much paper does it
take to wrap each size of box?
Each small box uses
feet of paper and each large one uses
feet.
Answer:
Step-by-step explanation:
It takes 8 feet to wrap the small box and 12 feet to wrap the large box
Step-by-step explanation:
The cheerleaders from Campo high school are doing a gift wrapping fundraiser at a clothing store
Yesterday, they wrapped 36 small clothing boxes and 25 large clothing boxes, using a total of 588 feet of wrapping paper
The day before, they wrap 27 small clothing boxes and 29 large clothing boxes, using a total of 564 feet of gift wrap
We need to find how much paper it takes to wrap each size of box
Assume that they need x feet to wrap a small box and y feet to wrap a large box
∵ The small box is wrapped by x feet
∵ The large box is wrapped by y feet
∵ They wrapped 36 small clothing boxes and 25 large clothing
boxes, using a total of 588 feet
∴ 36x + 25y = 588 ⇒ (1)
∵ They wrapped 27 small clothing boxes and 29 large clothing
boxes, using a total of 564 feet
∴ 27x + 29y = 564 ⇒(2)
Now we have a system of equation to solve it
Multiply equation (1) by -3 and equation (2) by 4 to eliminate x
∵ -108x - 75y = -1764 ⇒ (3)
∵ 108x + 116y = 2256 ⇒ (4)
- Add equations (3) and (4)
∴ 41y = 492
- Divide both sides by 41
∴ y = 12
- Substitute the value of y in equation (1) or (2)
∵ 27x + 29(12) = 564
∴ 27x + 348 = 564
- Subtract 348 from both sides
∴ 27x = 216
- Divide both sides by 27
∴ x = 8
It takes 8 feet to wrap the small box and 12 feet to wrap the large box
Line m is tangent to the circle. Find the indicated measure
Answer:
105°
Step-by-step explanation:
The measure of an inscribed angle is half the measure of the arc it subtends. For an arc of 210°, an inscribed angle that subtends it will have a measure of 105°.
We normally think of the sides of an inscribed angle as being a chord. However, that chord can be considered part of a secant. When the two points of intersection with the circle get arbitrarily close together, the chord becomes a point, and the secant becomes a tangent.
That is, the angle made by this geometry is simply a degenerate case of an inscribed angle. The relationship with the arc measure is unchanged.
m∠1 = 105°
