Answer:
Yes
Step-by-step explanation:
A triangle is a "right" triangle if its lengths fullfil the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]
Here, a and b are the shorter "legs" of the triangle, adjacent to its right angle, while c is the "hypotenuse," the longest side and the one opposite the right angle.
If we call the 1.9 cm and 2.7 cm our legs, the sum of their squares is:
[tex]2.7^2+1.9^2=10.9[/tex] cm
While squaring our hypotenuse gives us
[tex]3.3^2=10.89[/tex] cm
The fact that we measured the triangle's side lengths to 1 decimal point of accuracy means that there's a little margin of error baked into the measurement. The two previous calculations are within 0.01 cm of each other, which is more than close enough, so we can say that yes, this could be a right triangle.

The volume of a sphere is [tex]\frac{4}{3}\pi r^{3}[/tex]
First, let's find the diameter of the large sphere.
If D=12, then R=6
[tex]\frac{4}{3}\pi 6^{3}=288\pi[/tex]
Then, we need to find the volume of the smaller sphere
[tex]\frac{4}{3}\pi 3^{3}=36\pi[/tex]

What is an equation of the line that passes through the point (2, 2) and is parallel to
the line x -
2y = 4?
Answer:
you wold have to graph it just put it in the caculater like that
Step-by-step explanation:
Answer: y- 2 = -1/2(x - 2)
Step-by-step explanation:
We need to rewrite it as y=mx+b.
x - 2y = 4
2y = - x + 4
y = -1/2x + 4/2
y = -1/2x + 2
The slope for x - 2y = 4 is -1/2.
In addition, the slope of two parallel line would be the same, the slope of the line that pass through the point (2,2) would be -1/2.
y- y1 = m(x- x1)
y- 2 = -1/2(x - 2)

Answer:

Step-by-step explanation:
We know that a right angle is 90 degrees. So we can make the equation [tex]35+4x+7=90.[/tex] Now, we can solve fore X! We can combine 35 and 7 to make the equation [tex]4x+42=90[/tex]. In order to isolate x we have to subtract 42 from both sides, getting us the equation [tex]4x=48.[/tex] Now, in order to isolate x we must divide each side by 4, getting us the equation [tex]12=x[/tex]. To prove that x=12, we can subsitute x for 12. This means that we can do [tex]35+4(12)+7=90. Or, 35+48+7 =90,[/tex] which simplified, is 90=90, making x=12 true. Hope this helps :)

Are my answers for the conditional statement correct? I would just like to check them and if they're incorrect, could you let me know how to fix them? Thank you.
Statement: If I brush my teeth twice a day, then I will not get cavities.
Inverse: If I don't brush my teeth twice a day, then I will get cavities.
Truth Value: True
Converse: If I don't get cavities, then I am brushing my teeth twice a day.
Truth Value: True
Contrapositive: If I get cavities, then I am not brushing my teeth twice a day.
Truth Value: True
Statement: If p, then q
Inverse: If q, then p
Converse: If not p, then not q
Contrapositive: If not q, then not p.
We can see from the statement that p = brush teeth twice a day and q = not get cavities.
Thus:
Inverse: If I don't get cavities, then I brush my teeth twice a day. FALSE (for example, I might floss extra well instead. Brushing my teeth twice a day is not the only way to avoid cavities)
Converse: If I don't brush my teeth twice a day, then I get cavities. FALSE (for example, I might not eat a lot of sugar and thus I don't get cavities)
Contrapositive: If I get cavities, then I did not brush my teeth twice a day. TRUE
If this confuses you, try the example of p = cat and q = four legs. (i.e. the statement is If this is a cat, it has four legs). Try making the inverse, converse, and contrapositive, and see the truth of those statements.

x- 5/3=1
Answer:
x = 8/3 or 2 2/3
Step-by-step explanation:
x - 5/3 = 1
x - 5/3 + 5/3 = x
1 + 5/3 = 8/3 or 2 2/3
x = 8/3 or 2 2/3
Answer:
x = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
Given
x - [tex]\frac{5}{3}[/tex] = 1 ( multiply through by 3 to clear the fraction )
3x - 5 = 3 ( add 5 to both sides )
3x = 8 ( divide both sides by 3 )
x = [tex]\frac{8}{3}[/tex]

Find the arc length of the partial circle.
Answer:
12.42 units
Step by step explanation:
Given,
length of the radius = 2 units
Therefore, arc length of the complete circle = 2 × 3.14 × 2 units = 12.56 units
Therefore, arc length of the partial circle = 3/4 × 12.56 units
= 12.42 units

If a 18 ft tall tree casts a 9 ft long shadow
then how tall is an adult giraffe standing near it that casts a 7
ft shadow?
Answer:
[tex] \boxed{ \tt{the \: adult \: giraffe \: is \to \: 14 \: ft}}[/tex]
The height of the giraffe standing near it which casts a shadow of 7 feet is 14 feet.
What is Scale Factor?Scale factor is the ratio of the dimension of the given original object and the dimension of the new object from the original.
Given that,
Actual height of the tree = 18 feet
Height of the shadow = 9 feet
Actual height = 2 × Shadow height
So, here the scale factor is 2.
Given Shadow height of the giraffe = 7 feet
Actual height of the giraffe = 2 × height of shadow of the giraffe
= 2 × 7 feet
= 14 feet
Hence the height of the giraffe is 14 feet.

According to Ohm's law, the electric current I, in
amperes, in a circuit varies directly as the voltage V.
When 14 volts are applied, the current is 2 amperes.
What is the current when 29 volts are applied?
Answer:
4 ampers
Step-by-step explanation:
WHEN 12 VOLTS ARE APPLIED, THE CURRENT IS 4 AMPERES.
The current when 29 volts are applied is; 4.14 amperes.
According to the question;
The electric current I, in amperes, in a circuit varies directly as the voltage V.
In essence;
I/V = constant.
Therefore;
I1/V1 = I2/V2
where;
I1 = 2amperesV1 = 14voltsI2 = ?V2 = 29Therefore; we have;
2/14 = I2/29By cross product;
14 × I2 = 29 × 2I2 = 58/14I2 = 4.14 amperes.
In conclusion, the current when 29V voltage is applied is; 4.14 amperes.

The length of the guy why supporting a cell tower is 120 m the guy wire is anchored to the ground at a distance of 80 m from the base of the tower to the nearest hundredth of a meter how tall is the tower?
Complete Question
The length of the guy wire supporting a cell tower is 120 m. The guy wire is anchored to the ground at a distance of 80 m from the base of the tower to the nearest hundredth of a meter how tall is the tower?
Answer:
89.44m
Step-by-step explanation:
We solve this question using the Pythagoras Theorem
This is given as:
Hypotenuse² = Opposite ² + Adjacent ²
Hypotenuse = Length of the guy wire = 120m
Adjacent = Distance from the base of the tower = 80m
Opposite = Height of the building = x
Hence:
120² = x² + 80²
Collect like terms
x² = 120² - 80²
x = √120² - 80²
x = √(8000)
x = 89.4427191 m
Approximately the height of the tower is = 89.44m

Answer:
8.164
Step-by-step explanation:
The circumference of the ball is 8.164 inches.

Since the diameter of the tennis ball is 2.6 inches
So here the radius should be half i.e. 1.3 inches
Now we know that
Circumference = [tex]2\pi r\\\\[/tex]
= 2(3.14)(1.3)
= 8.164 inches
