[tex]-\frac{2}{15}[/tex]
Step-by-step explanation:
[tex]\frac{2-\left|-\frac{2}{3}-2\left(-\frac{1}{5}\right)\right|}{-13}[/tex]
[tex]\mathrm{Apply\:rule}:\quad \:-a\left(-b\right)=ab[/tex]
[tex]-2\left(-\frac{1}{5}\right)=2\cdot \frac{1}{5}[/tex]
[tex]=\frac{2-\left|-\frac{2}{3}+2\cdot \frac{1}{5}\right|}{-13}[/tex]
[tex]-\frac{2}{3}+2*\frac{1}{5}=-\frac{4}{15}[/tex]
[tex]=\frac{2-\left|-\frac{4}{15}\right|}{-13}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{-b}=-\frac{a}{b}[/tex]
[tex]=-\frac{2-\left|-\frac{4}{15}\right|}{13}[/tex]
[tex]Simplify\;2-|-\frac{4}{15}|:\frac{26}{15}[/tex]
[tex]=-\frac{\frac{26}{15}}{13}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{c}=\frac{a}{b\cdot \:c}[/tex]
[tex]\frac{\frac{26}{15}}{13}=\frac{26}{15\cdot \:13}[/tex]
[tex]=-\frac{26}{15\cdot \:13}[/tex]
[tex]\mathrm{Multiply\:the\:numbers:}\:15\cdot \:13=195[/tex]

The width of a rectangle is 3 yards less than its length. The perimeter is 130 yards. Find the length and width of the rectangle.
Answers
2L-6+2L=130
4L=136
L=34 W =31
Answer:
Length = 34 yards
Width = 31 yards
Step-by-step explanation:
Perimeter = 2(l + w), where l = length, and w = width
We know that w, is l - 3
130 = 2(l + l - 3)
130 = 4l - 6
136 = 4l
l = 34
Width is 3 less than 34, or 31

Triangle D E F with measures as described in the text.
© 2019 StrongMind. Created using GeoGebra.
What is the measurement of EF?
If necessary, round your answer to two decimal places, like this: 42.53
Answers
Answer:
EF = 1.98
Step-by-step explanation:
Sin = opposite/hypotenuse; Cos = adjacent/hypotenuse ;
Tan = opposite/adjacent
DF = 4.5 which is the hypotenuse. So using the equation for Sin
Sin 26° = opposite/hypotenuse
Sin 26° = EF/4.5
.44 = EF/4.5 solving .44(4.5) = EF ; 1.98 = EF

The two purchases can be described by ...
3b +2d = 35
2b +d = 22
Subtracting the first equation from twice the second, we get ...
2(2b +d) -(3b +2d) = 2(22) -(35)
b = 9 . . . . . . . . simplify

1. How many triangles are created in the following situation:
Answers
Answer:
Step-by-step explanation:
We can use:
[tex]\frac{12}{sin35} = \frac{16}{sinB}[/tex]
Solve for sinB
[tex]sinB=\frac{16(sin35)}{12}[/tex]
The answer we get from that is: 0.76
With that answer, we can do:
[tex]B=sinx^{-1}(0.76)[/tex]
So, since the calculator did NOT put out an error, there is 2 such triangles.
Only 1 triangle can be formed by angle m∡A = 35°, a = 12, b = 16.
How many triangles are created in the following situation:m∡A = 35°, a = 12, b = 16. is to be determined.
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.
Here, the data given is m∡A = 35°, a = 12, b = 16,
Since one angle m∡A = 35° is given between the two sides a = 12, b = 16,.
There is only one triangle that can be made through the given data.
because when we plot the measures only one side can be added without calculation in order to complete the triangle.
Thus, only 1 triangle can be formed by m∡A = 35°, a = 12, b = 16.

Charlotte buys a ticket to go to a baseball game. The total includes a charge of 7% of the original price for extra fees. If Charlotte pays a total of $44.94, how much was the original price of the ticket?
Answers
Answer:
$41.7942
Step-by-step explanation:
First you need to change 7% into a decimal (you do this by dividing it by 100)
7÷100=0.07
Then, you multiply 0.07 with 44.94
0.07×44.94=3.1458
3.1458 is the amount for the extra fees.
After that, you subtract 44.94 with 3.1458
44.94-3.1458=41.7942
This gives us the original price, so, the original price is $41.7942.

A) Angle A is an obtuse angle.
B) Angle A is a straight angle.
C) Angle B is an acute angle.
D)Angle B is a right angle.
Answers
Supplementary angles = AngleA + AngleB = 180
Right angle = 90
Angle B = 90 Angle A = X
180 - 90 = X = 90 they can equal to each other.

You go to Ihop and order two servings of pancakes and a
-cup of coffee. The cost of the coffee is $2.00. You leave a
20% tip. The total bill is $14.40. How much does one serving
of pancakes cost?
Answers
Answer: $4.76
To find the answer you need to find out the total before the 20% tips to find this you need to subtract 14.40 and 20% which = $11.52.If the coffee was $2 you also need to subtract that so the equation would be (11.52-2.00=9.52).Lastly the question is asking you for the price of one serving of pancakes but we have the answer for 2 which is $9.52.To find the price of of 1 serving you need to divide $9.52 by 2 = $4.76.So your answer is $4.76 for 1 serving of pancakes.

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
The given expression is
csc² (x) - 2csc(x) cot(x) + cot² (x) = tan² (x/2)
Proceed LHS
csc² (x) - 2csc(x) cot(x) + cot² (x)
⇒ (1/sin²(x) ) - 2(1/sin(x) )(cos(x)/sin(x)) + (cos(x)/sin(x))²
⇒ (1 - 2cos(x) + cos(x)²)/sin(x)²
⇒ (1 - 2cos(x) + cos(x)²)/sin(x)²
⇒ (1 - cos(x))²/sin(x)²
⇒ (1 - cos(x))²/sin(x)²+
⇒ [(1 - cos(x))/sin(x)]² [ since tan(x/2) =(1 - cos(x))/sin(x)]
⇒ [ tan(x/2) ]²
⇒ tan²(x/2) = RHS
Hence proved.
