In rectangle ABCD, the diagonals intersect each other at point 0 and mABD=30°.
Find BC if AC = 16 in.
Answer:
Step-by-step explanation:
The length of the diagonal BC is equal to 18.47in
Data;
m∠ABD = 30°
BC = ?
AC = 16 in
Length BC
Since the length of AC = 16in and angle m∠ABD = 30°, let us consider that the edges form a right angle triangle.
We can use trigonometric ratio to find the length BC since it is the length of the diagonal.
Since we have the value of opposite and angle, we can find the hypothenuse using sine angle.
The length of the diagonal BC is equal to 18.47in

The perimeter of a rectangle is 60 cm. The ratio of length to width is 3:2. Find the length and width of the rectangle.
Given :
The Perimeter of the rectangle is 60 cmThe ratio of the length to the width is 3:2.To Find :
The Length and width of the rectangle .⠀
Solution :
We know that,
[tex]\qquad{ \bold{ \pmb{2(Length + Breadth ) = Perimeter_{(rectangle)}}}}[/tex]
Let's assume the length of the rectangle as 3x inches. and the width is 2x inches.
⠀
Now, Substituting the given values in the formula :
[tex]\qquad \dashrightarrow{ \sf{2(3x + 2x )= 60}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{2(6x)= 60}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{12x= 60}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{x= \dfrac{60}{12} }}[/tex]
[tex]\qquad \dashrightarrow{ \bf{x= 5}}[/tex]
Therefore,
[tex]\qquad { \pmb{ \bf{ Length _{(rectangle)} = 3x \: = 3(5) = 15 \: inches}}}\:[/tex]
[tex]\qquad { \pmb{ \bf{ Width _{(rectangle)} = 2x = 2(5) = 10 \: inches}}}\:[/tex]
HELP!! I dont know which one is the correct answer. I'll give brainliest
Answer:
[tex]\sf g = 13.18 \ units[/tex]
explanation:
the "g" refers to the opposite side of angle G
First solve for angle E:
E + 60° + 45° = 180°
E = 180° - 105°
E = 75°
Then using sine rule:
[tex]\sf \dfrac{a}{sin(A)} = \dfrac{b}{sin(B)}[/tex]
[tex]\rightarrow \sf \dfrac{18}{sin(75)} = \dfrac{g}{sin(45)}[/tex]
[tex]\rightarrow \sf \dfrac{18*sin(45)}{sin(75)} = g[/tex]
[tex]\rightarrow \sf g = 13.18 \ units[/tex]

If the width of a rectangle plot is “x” and the length of the plot is 100-x/2, what is the maximum area of the plot?
Answer:Let x = length of the plot (in meters).
Then the two lengths use up 2x meters of the fencing,
. . . leaving 100 - 2x meters for the two widths.
This means each width is (100 - 2x)/2 = 50 - x meters.
The area of a rectangle is: Length x Width
. . . so we have: . A .= .x(50 - x)
We have a <u>parabola</u>: . A .= .- x<sup>2</sup> + 50x</sup>
We know that this parabola opens down (don't we?)
. . . so its vertex must be the highest point.
We're expected to know that the vertex is at: . x = -b/2a
For this problem, a = -1, b = 50, so we have: . x = -50/(2(-1) = 25
We have maximum A when x = 25.
This leaves 50 - x = 25 for the width.
Therefore, for maximum area, make the plot a 25-by-25 square.

I understand mostly, but the subtraction sign throws me off...
Answer:
x = 2
Step-by-step explanation:
What is needed to solve this equation is a common denominator. With a common denominator, you can get rid of subtracted fractions.
First, factor the denominator on the left side of the equation:
[tex]\frac{3}{(x + 3)(x - 2)} = \frac{2}{x+3} - \frac{1}{x-2}[/tex]
Then, create a common denominator on the right:
[tex]\frac{3}{(x + 3)(x - 2)} = \frac{2}{x+3}(\frac{x-2}{x-2}) - \frac{1}{x-2}(\frac{x+3}{x+3})[/tex]
[tex]\frac{3}{(x + 3)(x - 2)} = \frac{2(x - 2) - 1(x + 3)}{(x+3)(x-2)}[/tex]
Put everything on one side:
[tex]0 = \frac{2(x - 2) - 1(x + 3)}{(x+3)(x-2)} - \frac{3}{(x + 3)(x - 2)}[/tex]
[tex]0 = \frac{2(x - 2) - 1(x + 3) - 3}{(x+3)(x-2)}[/tex]
[tex]0 = \frac{2x - 4 - x - 3 - 3}{(x+3)(x-2)}[/tex]
[tex]0 = \frac{x - 10}{(x+3)(x-2)}[/tex]
set each term equal to zero:
x - 10 = 0
x = 10
x + 3 = 0
x = -3
x - 2 = 0
x = 2 is the answer, since it is the only answer which is listed in the multiple choice question.
Find the lengths of the missing sides if side a is opposite angle A, side b is opposite angle B, and side c is the hypotenuse.
cos(B) = 4/5 a=90
Answer:
Step-by-step explanation:
cosB = a/c = 4/5
so c = 5a/4 = 5*90/4 = 112.5
b² = c² - a² = 112.5² - 90² = 4556.25
b = 67.5

How many solutions do two parallel lines have?
Parallel lines don't have any solutions since they never intersect

In a certain normal distribution, find the mean μ when σ = 5 and 5.48% of the area lies to the left of 78.
The mean of the normal distribution, using the formula for the z-score, considering the given data, is of 86.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The standard deviation is of [tex]\sigma = 5[/tex].5.48% of the area lies to the left of 78, hence when X = 78, Z has a p-value of 0.0548, that is, Z = -1.6.Then:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.6 = \frac{78 - \mu}{5}[/tex]
[tex]78 - \mu = -1.6(5)[/tex]
[tex]\mu = 86[/tex]

Answer:
$7,185 see below ↓
explanation:
With median, it is about the number that appears the most, and since the closest it gets is between $7,071 and $7,195, we have to pick the number that averages in-between which in this case is 7,185.

QRST WXYZ. The area of QRST is given. Find the area of WXYZ.
Answer:
b. 1296 in^2
Step-by-step explanation:
The area of a rectangle is calculated by multiplying width and length:
The length of the QRST is 144 since its width is given as 8 to find the length:
144/8 = 18 is the length of the QRST
it is stated that the two rectangles are similar so their widths and lengths are proportional.
Let x represent the width of WXYZ:
8/24 = 18/x cross multiply expressions
8x = 432 divide both sides by 8
x = 54 now we can calculate area of WXYZ
24*54 = 1296
