Answer:
21.4 feets
Step-by-step explanation:
Using Pythagoras rule :
The length of the string:
Hypotenus = sqrt(opposite² + adjacent²)
Length of string = sqrt(17² + 13²)
Length = sqrt(289 + 169)
Length of string = sqrt(458)
Length of string = 21.400
Length = 21.4 feets
Anna went to the store to buy a new dress. The dress she chose was 30% off the original price. What was the original price of the dress that was marked down dollars 13.95?
Answer:
$46.5
Step-by-step explanation:
Let X be the original price.
0.3X=13.95, X=13.95/0.3, X=46.5.
Answer:
18.135
Step-by-step explanation:
13.95×30/100=4.185
13.95+4.185=18.135

Solve the triangle in the figure.
Question options:
A)
BC = 9; m∠A = 53.1°; m∠B = 6.9°; m∠C = 90°
B)
BC = 11; m∠A = 42.8°; m∠B = 47.2°; m∠C = 90°
C)
BC = 19; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
D)
BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
Answer:
D)
BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
Step-by-step explanation:
15²-12² = 9²
BC = 9
sin B = 12/15 = 0.8
∠B = 53.1°
The solution will be BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°. The correct option is D.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the sum of the square of the other two sides.
The triangle ABC is a right triangle. The new path is in front of the right angle, therefore it is the hypotenuse. To find the length of the hypotenuse we use the Pythagorean theorem:
H² = P² + B²
The length BC will be calculated as below:-
15²-12² = 9²
BC = 9
The angle B will be calculated as below:-
sin B = 12/15 = 0.8
∠B = 53.1°
Therefore, the solution will be BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°. The correct option is D.

Which value of x results in equal outputs for
j(x) = 3x − 2
and b(x) = |x + 2|
Answer:
Step-by-step explanation:
J(x)=b(x)
3x-2=|x+2|
3x-2=±(x+2)
when 3x-2=x+2
3x-x=2+2
2x=4
x=4/2=2
when 3x-2=-(x+2)
3x-2=-x-2
4x=-2+2=0
x=0
it is rejected as 0-2≠|0+2|
or -2=2
so x=2

determine the measure of each angle. 4x - 90= ? Degree
Answer:
4x - 90= 90
Explain:
Simplifying
(4x + -90) = 90
Reorder the terms:
(-90 + 4x) = 90
Remove parenthesis around (-90 + 4x)
-90 + 4x = 90
Solving
-90 + 4x = 90
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '90' to each side of the equation.
-90 + 90 + 4x = 90 + 90
Combine like terms: -90 + 90 = 0
0 + 4x = 90 + 90
4x = 90 + 90
Combine like terms: 90 + 90 = 180
4x = 180
Divide each side by '4'.
x = 45
Simplifying
x = 45

If you had a right triangle with legs measuring 40 yards and 100 yards long,
what would be the length of the hypotenuse? Round your answer to the
nearest yard if necessary. *
70 yd
92 yd
108 yd
146 yd
9514 1404 393
Answer:
(c) 108 yd
Step-by-step explanation:
For hypotenuse c and legs a and b, the Pythagorean theorem tells you the relation is ...
c² = a² +b²
Solving for c, we have ...
c = √(a² +b²)
c = √(40² +100²) = √(1600 +10000) = √11600
c ≈ 107.70 . . . . yards
The length of the hypotenuse is about 108 yards.

To get rid of a radical we multiply the radical by itself, so we multiply [tex]\frac{3}{\sqrt{2}} by \frac{\sqrt{2}}{\sqrt{2}}[/tex]

#3:
[tex]\sqrt\frac{2}{5}[/tex] is the same as [tex]\frac{\sqrt{2}}{\sqrt{5}}[/tex] so we multiply by [tex]\frac{\sqrt{5}}{\sqrt{5}}[/tex] so we get [tex]\frac{\sqrt{10}}{5}[/tex].

*An algebraic expression is a mathematical phrase that can contain numbers, variables (letters) and operations (+, -, x ÷)
Consider this expression. x-4/2(x+4)
Answer:
Option A
Step-by-step explanation:
We will simplify the expressions given in the options first,
x² - 16 = (x - 4)(x + 4)
2x + 8 = 2(x + 4)
x² + 8x + 16 = (x + 4)²
Option A
[tex]\frac{x^2-16}{2x+8}[/tex] × [tex]\frac{x+4}{x^2+8x+16}[/tex]
= [tex]\frac{(x+4)(x-4)}{2(x+4)}\times \frac{(x+4)}{(x+4)^2}[/tex]
= [tex]\frac{x-4}{2(x+4)}[/tex]
Option B
[tex]\frac{2x+8}{x^2-16}[/tex] ÷ [tex]\frac{x^2+8x+16}{x+4}[/tex]
= [tex]\frac{2(x+4)}{(x+4)(x-4)}[/tex] ÷ [tex]\frac{(x+4)^2}{(x+4)}[/tex]
= [tex]\frac{2}{(x-4)}\times \frac{1}{(x+4)}[/tex]
= [tex]\frac{2}{x^2-16}[/tex]
Option C
[tex]\frac{x^2-16}{2x+8}[/tex] ÷ [tex]\frac{x+4}{x^{2}+4x+16}[/tex]
= [tex]\frac{(x-4)(x+4)}{2(x+4)}\times \frac{(x+4)^2}{(x+4)}[/tex]
= [tex]\frac{(x-4)(x+4)}{2}[/tex]
Option D
[tex]\frac{2x+8}{x^2-16}\times \frac{x^2+8x+16}{x+4}[/tex]
= [tex]\frac{2(x+4)}{(x-4)(x+4)}\times \frac{(x+4)^2}{(x+4)}[/tex]
= [tex]\frac{2(x+4)}{(x-4)}[/tex]
Therefore, Option A is the answer.

What is the measure of the missing angle?
Answer:
79 degrees
Step-by-step explanation:
You add the two angles and get 79. Then you subtract it from 180 because it is a straight angle. 180-101=79
Answer:
79
Step-by-step explanation:
28+73+x=180
a straight line is 180. That's how I got what it is equal to.
28+73= 101
101+x=180
subtract
180-101= 79
