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.
write the equation of the line pictured in standard form
Answer:
x+2y=4
Step-by-step explanation:
y=-1/2x+2 multiply both sides by 2
2y=-1x+4
2y+x=4 or x+2y=4 standard form
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

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.
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
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

Please help with these 3 questions about simplifying square roots...
Answer:
#2:
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]
to get [tex]\frac{3\sqrt{2}}{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].
#4:
We combine like terms to get [tex]-2\sqrt{2} + 4\sqrt{3}[/tex]

The Mount Rushmore Monument is 60 feet tall. A model of the monument is sold in the gift shop. If the model was made using a scale of 1 inch = 40 inches, how tall is the model?
Answer:huh
Step-by-step explanation:huh
The model is 28800 inches tall if the Mount Rushmore Monument is 60 feet tall. A model of the monument is sold in the gift shop.
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
It is given that:
The Mount Rushmore Monument is 60 feet tall. A model of the monument is sold in the gift shop.
As we know, unit conversion can be defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
1 feet = 12 inches
60 feet = 60x12 = 720 inches
The scale f 1 inch = 40 inches
720 inches after scale:
= 720x40
= 28800 inches
Thus, the model is 28800 inches tall if the Mount Rushmore Monument is 60 feet tall. A model of the monument is sold in the gift shop.

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
