The surface area of a cube is 328.56 square inches. How long are it’s sides?
Answer:
7.4 in
Step-by-step explanation:
Surface area of a cube = 6s²
(where s is the side length)
Given:
SA = 328.56 in²Substituting the given value into the formula and solving for s:
⇒ 328.56 = 6s²
⇒ 328.56 ÷ 6 = 6s² ÷ 6
⇒ 54.76 = s²
⇒ s = √54.76
⇒ s = 7.4 in
TSA of a cube=328.56
Side be x
6x²=328.56x²=54.76x=√54.76x=7.4in30 POINTS!! Find the equation of the axis of symmetry of the parabola. Each box in the grid represents 1 unit.

PLEASE HELP !! Find the volume of the sphere.
Step-by-step explanation:
(4/3)•πr³
= 4/3 • π • (1/4)³
= π/48 cubic units or 150.86 cubic units
Volume of sphere is [tex]\frac{11}{14}[/tex] cubic unit.
What is Volume of sphere?The volume of sphere is the measure of space that can be occupied by a sphere. A sphere is a three-dimensional shape that has no edges or vertices.
Volume of sphere = [tex]4\pi r^{2}[/tex]
Given
Radius of sphere = [tex]\frac{1}{4}[/tex] unit
Volume of sphere = [tex]4\pi r^{2}[/tex]
= 4 × [tex]\pi[/tex] × [tex](\frac{1}{4} )^{2}[/tex]
= 4 × [tex]\frac{22}{7}[/tex] × [tex]\frac{1}{16}[/tex]
= [tex]\frac{11}{14}[/tex]
Hence, Volume of sphere is [tex]\frac{11}{14}[/tex] cubic unit.

Sabrina wants to learn a new language. She downloads an app and sees that it comes with an immediate discount of 55% off a yearly membership. If the yearly membership costs $139.99, how much money will Sabrina save? How much money will the yearly membership with the discount cost?
Answer:
$56.
$83.99.
Step-by-step explanation:
She will save 40% of $139.99
= 0.40 * 139.99
= $56.
With the discount membership costs:
139.99 - 56
= $83.99.
According to the information given, what can you determine about the triangles formed by Tyler, the mirror, and the peak? How do you know the relationship between the two triangles? (4 points: 2 points for correctly describing the triangles, 2 points for the explanation)
Answer:
height of the peak AB is 40 feet.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Step-by-step explanation:In the figure attached, A is the peak of mountain AB, ED is Tyler who is 6 feet high. Mirror placed at C, is 20 feet from the base of peak. Tyler is 3 feet away from the mirror.1). When Tyler sees the peak in the mirror, angle of incidence " i " and angle of reflection " r " made by incident ray AC and reflected ray EC will be equal.Now we can easily say ∠ r = ∠ E ( Alternate angles )∠ i = ∠ A ( alternate angles)Since ∠ i = ∠ r Therefore, ∠ A = ∠ E∠B = ∠D = 90°and ∠ACB = ∠ECDHence ΔABC is similar to ΔCDE.2). Corresponding sides of these similar triangles are AB and ED, BC and CD, AC and CE.3). tanE = tanE = 0.5 ∠ E = degreesNow ∠E = ∠A = 26.57°Therefore, tan(26.57) = 0.5 = AB = Therefore, height of the peak AB is 40 feet.

Write the standard form equation of the line parallel to y = 2x – 1 that contains the point (2,-7)
Answer:
[tex]y=2x+3[/tex]
Step-by-step explanation:
The slope-intercept form is [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
[tex]y=mx+b[/tex]
Using the slope-intercept form, the slope is 2.
[tex]m=2[/tex]
So in order for us to find an equation that is parallel, the slopes must be equal. We need to find the parallel line using the point-slope formula.
We use the slope 2 and a given point [tex](2,7)[/tex] to substitute for x1 and y1 in the point-slope form [tex]y-y^1 = m (x-x^1)[/tex], which is derived from the slope equation: [tex]m=\frac{y2-y1}{x2-x1}[/tex]
Now we simplify the equation and keep it in point-slope form.
[tex]y-7=2[/tex] × [tex](x-2)[/tex]
Simplify [tex]2[/tex] × [tex](x-2)[/tex]
[tex]y-7=2x-4[/tex]
[tex]Rewrite.~y-7=0+0+2~x~(x-2)[/tex]
[tex]Simplify~ by~adding~zeros.~y-7=2 ~x~(x-2)[/tex]
[tex]Apply~the~distributive~property.~y-7=2x+2~X~-2[/tex]
[tex]Multiply~2~by~-2.~y-7=2x-4[/tex]
Last, We move all terms not containing y to the right side of the equation.
Add 7 to both sides of the equation.
[tex]y=2x-4+7[/tex]
Add −4 and 7 and your answer will be: [tex]y=2x+3[/tex]

Complete the vector to fully describe the single transformation which takes shape a to shape b translate shape a by the sector.
The single transformation that maps shape a onto shape b is [tex]\left[\begin{array}{c}-5&-5\end{array}\right][/tex]
How to determine the vector transformation?From the figure, we have the following highlights
Both triangles are congruentTriangle B is 5 units down from triangle ATriangle B is 5 units left of triangle AThe above highlights mean that the triangle A must be translated 5 units left and 5 units down to get triangle B.
This is represented as:
(x,y) -> (x - 5, y - 5)
By vector representation, we have:
[tex]\left[\begin{array}{c}-5&-5\end{array}\right][/tex]
Hence, the single transformation that maps shape a onto shape b is [tex]\left[\begin{array}{c}-5&-5\end{array}\right][/tex]

What is an equation of the line that passes through the point (-5,-2) and is parallel to the line x-y=5
Answer:
y = x + 3
Step-by-step explanation:

1. Jacob buys a laptop for $356 plus tax of 6.25%. If he gives the
Cashier $400, how much change does he receive back?
Answer: $21.75
Step-by-step explanation:
356*.0625 = 22.25
so 6.25% of 356 = $22.25
356+22.25 = $378.25 (this is how much he owes)
400-378.25 = $21.75

Step-by-step explanation:
1. Find the area of the circles:
[tex]a = r^{2}\pi[/tex]
[tex]a = \frac{3}{4} * 4^{2} *\pi[/tex]
[tex]a = 37.7[/tex]
Since there are 2 circles we need to times this value by 2:
[tex]37.7 *2 = 75.4[/tex]
2. Now let's find the area of the regtangular figures
[tex]4 * 6 * 2 = 48[/tex]
3. Now the circular part of the outside of the cylinder
[tex]4 * 2 * \pi = 25.13[/tex]
[tex]25.13 * 6[/tex] = 150.78
Since this is not the actual value we need to find 25% of this value and subtract it.
[tex]150.78 - 150.78*0.25 = 150.78 - 37.7 = 113.08[/tex]
4. Let's add these values together
[tex]113.08 + 48 + 37.7[/tex] = 198.78m

in how many years does Rs 2000 amount to Rs 2420 at 10% p.a compound interest?
2 years
Step-by-step explanation:
GivenPrinciple = Rs. 2000
Rate of Interest = 10%
Amount = Rs. 2420
Formula used = P(1+R/100)^T
=> 2420 = 2000 ( 1+10/100)^T
by taking LCM of underlined equation.=> 2420 = 2000 (10+1/10)^T
=> 2420 = 2000 (11/10)^T
=> 2420/2000 = (11/10)^T
=> 121/100 = (11/10)^T
121 = 11²100 = 10²=> 11/10 = (11/10)^T
=> 2 years.
