Step-by-step explanation:
A right square prism has a volume of 360 cubic units. Which could be the dimensions, in units, of the prism? Select three options.
The dimensions, in units, of the right square prism are 3 by 3 by 40, 2.5 by 12 by 12 and 3.6 by 10 by 10.
What is of volume of solid?
Volume of solid is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
The volume of a right square prism can be calculated using the following formula.
[tex]V=a^2h\\[/tex]
Here, (a) is the side length of the base and (h) is the height.
The right square prism has a volume of 360 cubic units. Lets check all the options, whose volume is equal to 360 cubic units.
The dimensions of the first option is 3 by 3 by 40. Thus, the volume of it,[tex]V=3^2\times40\\V=360\rm\; units^3[/tex]
The dimensions of the second option is 4 by 4 by 20. Thus, the volume of it,[tex]V=4^2\times20\\V=320\rm\; units^3[/tex]
The dimensions of the third option is 5 by 5 by 14. Thus, the volume of it,[tex]V=5^2\times14\\V=350\rm\; units^3[/tex]
The dimensions of the fourth option is 2.5 by 12 by 12. Thus, the volume of it,[tex]V=12^2\times2.5\\V=360\rm\; units^3[/tex]
The dimensions of the fifth option is 3.6 by 10 by 10. Thus, the volume of it,[tex]V=10^2\times3.6\\V=360\rm\; units^3[/tex]Hence, the dimensions, in units, of the right square prism are 3 by 3 by 40, 2.5 by 12 by 12 and 3.6 by 10 by 10.

You work in a department store and sell a dress that is on sale for $58.80. If the regular price of the dress is $98, what is the discount?
Answer:
The discount is 60%
Step-by-step explanation:
We can set up a proportion to solve for the discount percent. On the left I will put costs in dollars and on the right the percentage of the cost, with the regular price on the top.
-> Percents are divided by 100 to become decimals
[Start]
[tex]\frac{98}{58.8}=\frac{1}{x}[/tex]
[Cross-multiply]
98 * x = 1 * 58.8
98x = 58.8
[Divide both sides of the equation by 98]
x = 0.6
[Multiply both sides of the equation by 100 to get a percent]
The discount is 60%

Jen ran 3/4 mile in 18 minutes at 9 am and 2 1/4 miles in 27 minutes at 6 pm. Is this proportional or non proportional?
Please explain why.
If anyone can help me with this problem that will be great, thank you guys so much!!!
Answer:
It's non-proportional
Step-by-step explanation:
You could tell every 1/4 mile is 6 minutes, so every other number should be a multiple of 6 if it is a multiple of 1/4. 27 is not a multiple of 6.
Vance wants to construct a circle tangent to all three sides of the acute, scalene triangle LMN using the following steps.
He will draw altitudes from vertex L and vertex M, and mark their intersection point as O.
He will draw the perpendicular from point O to side MN, and mark the intersection point as P.
He will draw the circle centered at point O which will pass through point P.
Which part of Vance's plan requires revision?
A.
Vance should have found the intersection of two perpendicular bisectors of triangle LMN instead of two altitudes.
B.
Vance should have found the intersection of two angle bisectors of triangle LMN instead of two altitudes.
C.
Vance should have used the compass to draw a circle through point N instead of point P.
D.
Vance should have constructed all three altitudes instead of only constructing two altitudes.
In the construction of the tangent to the triangle, the part that needs revision is D. Vance should have constructed all three altitudes instead of only constructing two altitudes.
What is a triangle?It should be noted that a triangle simply means a polygon that's has three sides. Also, a triangle has there's edges as well as vertices.
In this case, in order to construct a circle tangent to all three sides of the acute, scalene triangle LMN, it should be noted that the three altitudes have to be taken into consideration.
This wasn't the case in the step given by Vance has only two altitudes were considered. Therefore, this should be the change that is required.

Factor completely 9xy 36x − 10y − 40. Prime (y − 4)(9x − 10) (y 4)(9x − 10) (y 4)(9x 10).
The complete factor of the polynomial 9xy + 36x − 10y − 40 is (9x − 10) (y+4). Then the correct option is C.
What is polynomial?Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Factor completely 9xy + 36x − 10y − 40.
Take 9x common from the first two terms and -10 from the last two terms. we have
9xy + 36x − 10y − 40
9x (y + 4) − 10 (y + 4)
Take y+4 common, then we have
(9x − 10) (y + 4)
The complete factor of the polynomial 9xy + 36x − 10y − 40 is (9x − 10) (y+4). Then the correct option is C.

12.5 cm
D
A
24.3 cm
Work out the size of angle x.
Give your answer correct to 1 decimal place.
hmm the answer is 45.cm because
Answer:
x = 123.6°
Step-by-step explanation:
Subdivide the trapezium into a rectangle and triangle.
The triangle is a right triangle with hypotenuse CD and height 12.5cm.
The base of the triangle is 24.3 - 16 = 8.3 cm
To find angle D, use the tan trig ratio:
[tex]tan(\theta)=\dfrac{O}{A}[/tex] where [tex]\theta[/tex] is the angle, O is the side opposite the angle A is the side adjacent the angle.
Therefore, for the right triangle:
[tex]\theta[/tex] = DO = 12.5A = 8.3[tex]\tan(\theta)=\dfrac{12.5}{8.3} \implies \theta=56.41583952... \textdegree[/tex]
In a quadrilateral, the sum of the angles between the parallel lines is 180°. Therefore, m∠C + m∠D = 180°
⇒ x + 56.41573952... = 180
⇒ x = 180 - 56.41573952...
⇒ x = 123.6° (1 dp)
Alternatively, calculate angle C of the right triangle and add it to 90° to find x.

Step-by-step explanation:
The points wont be absolute on the line since they are decimals so you could gather 2 points like (27,162) and (32,141) and calculate for y which is y2-y1/x2-x1 but it would not give you the right answer so you would need to use linear regression using 3 values. First Calculate the sum of the x-values, then the y -values. Now sum the products of each data point and then, calculate the sum of the x-values squared and the y-values squared. Finally, count the number of data points you have. In this case we have three data points (N=3), then use the Number of points you have times the x and y sums you got from squaring and adding to get the slope.

Step-by-step explanation:
4x-2=3x

x=2
Answer:
D. 6
Step-by-step explanation:
As the two base angles are equal, this implies that this is an isosceles triangle. This means that the sides opposite the base angles are also equal.
Therefore, AB = BC
⇒ 3x = 4x - 2
⇒ x = 2
If x = 2, then AB = 3 · 2 = 6

Find the value of F in the figure below
Answer: 1.2 mm
Step-by-step explanation:
Can someone please help me!!!
Answer:
-21
Step-by-step explanation:
Each of those lines is -3
If you look at the -10, it goes down 2 lines and goes to -16 meaning that if it only went down one line it would only go to -13
Showing that each line is worth -3
It goes down 2 lines from -16 (-6)
so if you go down 6 from -16 that would get you to -21
The answer is: -18
That is because, on the number line, they already have 2 numbers. They are -10 to -16. To go from -10 to -16, you subtract 2. Since the mark is the same distance away as -10 to -16 on this number line, you would subtract 2 from -16, which would be -18.
