A rectangle has a length of X +5 and a width of X -5 and has an area of 15 square units find the length and width of the rectangle.
Answer:L=11.3

To find:-Actual length and width of rectangle[tex] \\ [/tex]
Solution:-So to find actual length and width of rectangle, we need to find value of x.

[tex] \hookrightarrow \sf 15=x^2 - 25\\ [/tex]
[tex] \\ [/tex]
[tex] \hookrightarrow \sf 15 + 25=x^2 \\ [/tex]

Answer:
11. x = 32.6°
12. x = 27.0
Step-by-step explanation:
Question 11
[tex]\sin(\theta)=\dfrac{\textsf{opposite side}}{\textsf{hypotenuse}}[/tex]
Given:
[tex]\theta[/tex] = xside opposite angle = 7hypotenuse = 13[tex]\implies \sin(x)=\dfrac{7}{13}[/tex]
[tex]\implies x=\sin^{-1}\left(\dfrac{7}{13}\right)[/tex]
[tex]\implies x=32.6\textdegree \textsf{ (nearest tenth)}[/tex]
Question 12
[tex]\sin(\theta)=\dfrac{\textsf{opposite side}}{\textsf{hypotenuse}}[/tex]
Given:
[tex]\theta[/tex] = 64°side opposite the angle = xhypotenuse = 30[tex]\implies \sin(64\textdegree)=\dfrac{x}{30}[/tex]

Which measurements of two similar triangles are the same?
Step-by-step explanation:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion. In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

An open box with a square base is constructed so that it has a volume of 64in^3. The base needs to be made out of a material that costs twice as much as the sides. What are the dimensions of the box, what are the dimensions of the box x and y (x being the width and depth of the square dimensions, and y being the height of the box) which will minimize the cost of the box?
The volume of a box is the amount of space in the box
The dimensions that minimize the cost of the box is 4 in by 4 in by 4 in
How to determine the dimensions that minimize the costThe dimensions of the box are:
Width = x
Depth = y
So, the volume (V) is:
[tex]V = x^2y[/tex]
The volume is given as 64 cubic inches.
So, we have:
[tex]x^2y = 64[/tex]
Make y the subject
[tex]y = \frac{64}{x^2}[/tex]
The surface area of the box is calculated as:
[tex]A =x^2 + 4xy[/tex]
The cost is:
[tex]C = 2x^2 + 4xy[/tex] --- the base is twice as expensive as the sides
Substitute [tex]y = \frac{64}{x^2}[/tex]
[tex]C = 2x^2 + 4x * \frac{64}{x^2}[/tex]
[tex]C =2x^2 + \frac{256}{x}[/tex]
Differentiate
[tex]C' =4x - \frac{256}{x^2}[/tex]
Set to 0
[tex]4x - \frac{256}{x^2} = 0[/tex]
Multiply through by x^2
[tex]4x^3 - 256= 0[/tex]
Divide through by 4
[tex]x^3 - 64= 0[/tex]
Add 64 to both sides
[tex]x^3 = 64[/tex]
Take the cube roots of both sides
[tex]x = 4[/tex]
Recall that:
[tex]y = \frac{64}{x^2}[/tex]
So, we have:
[tex]y = \frac{64}{4^2}[/tex]
[tex]y = 4[/tex]
Hence, the dimensions that minimize the cost of the box is 4 in by 4 in by 4 in

Step-by-step explanation:
What values of x make 3 - 4x > 17 true?
Answer: x < -3.5
Step-by-step explanation:
Subtract 3 from both sides and we get
-4x > 14
We divide -4 on both sides, but be careful because we have to flip the sign since it's a negative number.

It takes Michelle 25 minutes to descend 850 feet of the beginner slope at Mount Washington. Find her rate of descent (slope). If Michelle begins her descent at a height of 1200 feet, find a linear equation to describe her skiing motion.
Answer:
h = 1200 - 34t
Step-by-step explanation:
25 minutes, descend 850 feet, so each minute, descend 850/25 = 34 feet
after t minutes, descend 34*t feet,
starting at 1200 feet, so the height is h = 1200 - 34t
Choose a different point that lies directly on the graph of the line...
Answer:
Step-by-step explanation:
You got it right: the point (0, -1) is another point on the graph of y = 3x - 1.
Substituting 0 and -1 back into the equation, y = 3x - 1:
-1 = 3(0) - 1
So the pint is also a solution to the equation.

Find the surface area of this shape.
Answer:
54 yds²
Step-by-step explanation:
Area of 1 side: 3*3=9
Number of sides: 6
6*9=54
Answer:
54 square yards
Step-by-step explanation:
This is a cube, as the width, height, and length are all the same. To fine the surface area of a cube, simply find the area of one side and multiply it by six, as a cube has six sides.
[tex]Area = Width*Height\\Area = 3 * 3\\Area = 9[/tex]
The area of one side of the cube is 9 square yards. Therefore, the surface area of the entire cube is 6 x 9 or 54 square yards.

josh sells 5 cycles in 2 days. after 20 days, how many cycles should be sold?
Answer:
50 cycles
Step-by-step explanation:
To find this out, we need to know how many cycles he sells a day. So as given he sells 5 cycles in 2 days, so what is half of five? While 2.5 cycles wouldn't make sense, lets use the variable to see what our answer would be approximately.
2.5 cycles x 20 days = 50 cycles.
So, in 20 days Josh would sell 50 cycles.
Answer:
50 cycles will be sold in 20 days
Step-by-step explanation:
2 days⇒5 cycles
1 day⇒5 divided by 2 days
20 days⇒5 cycles multiplied by 20 days divided by 2 days then the final answer is 50 cycles.

Write each sum as fraction with a denominator of 100 and as a decimal
Answer:
56/100 or 0.56
Step-by-step explanation:
you first need the dinominators to be the same so to figure that at you can do 100 divided by 10 which is 10. so to make the doniomators even you need to multipy the 2/10 by 10. so 2x10=20 and 10x10=100 so that makes the fraction 20/100. now you have 20/100 + 36/100 =? which makes it a lot easier. so now all you do is add ONLY THE NUMERATOR so you do 20+36 which is 56 and you keep the 100 and that 56/100.
To make it into a decimal, this one is easy because the denominater is 100 so you just take 56.0 and move the decimal two place values so its 0.56. :)
