Find the radius of a circle given that a central angle of measure pi/4 intercepts an arc of length 1.5in
Answers
Given:
Central angle = [tex]\dfrac{\pi}{4}[/tex]
Arc length = 1.5 in
To find:
The radius of the circle.
Solution:
We know that the formula for arc length is
[tex]s=r\theta[/tex]
Where r is radius and [tex]\theta [/tex] is the central angle in radian.
Substitute the given values in the above formula.
[tex]1.5=r\times \dfrac{\pi}{4}[/tex]
[tex]6=\pi r[/tex]
[tex]\dfrac{6}{\pi}=r[/tex]
[tex]\dfrac{6}{3.14}=r[/tex]
On further simplifiation, we get
[tex]r=1.910828[/tex]
[tex]r\approx 1.91[/tex]
Therefore, the radius of the circle is 1.91 in.

find the x-intercept
Answers
Answer:
(95/12,0)
Step-by-step explanation:
Answer:
(7.916, 0)
Step-by-step explanation:
In order to find the X-intercept, let y=0
12x + 5(0) = 95
12x = 95
95/12x = 7.91666...
Therefore, the x intercept is (7.916, 0)

More than in math represents addition, and the "a number" phrase is your variable, which is x.
(this is for if you're supposed to solve the equation)
7x=19-18
7x=1
x=1/7
I'm not really sure if you're supposed to actually solve the problem or write out the equation the question is asking for, but just with the context I'm given hopefully you don't have to) ;D
What is the density of the glass in 2.5 g/cm in kg/m
Answers
We are given:
Density of glass in g/cm³ = 2.5
Finding the density in kg/m³:
In converting 2.5 g/cm³ to kg/m³, we will first convert the g to kg
Converting the g to kg:
2.5 g/cm³ * 1
Since 1kg = 1000g, 1kg/1000g = 1
2.5 g/cm³ * 1kg / 1000g
the g in the numerator and the denominator will cancel out and we will get:
2.5 kg / 1000 cm³
Converting the cm³ to m³:
We know that 1 m³ = 10⁶ cm³
So, 10⁶ cm³ / 1 m³ = 1
Multiplying the density by 1
2.5 kg / 10³ cm³ * 1
2.5 kg / 10³ cm³ * 10⁶ cm³ / 1 m³
the cm³ in the numerator and the denominator will cancel out
2.5 * 10⁶ kg / 10³ m³
2.5 * 10³ * 10³ kg / 10³ m³
2.5 * 10³ kg / m³
2500 kg/m³

Congruent triangle
Answers
Answer:
x = 3
Step-by-step explanation:
exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles
97 + x = 64 + 27
x = 97 - 64 - 27 = 6
Answer: x=-6
you know that the interior angles of a triangle equal 180°. so lets find the remaining angle measure
64 + 27 = 91
180 - 91 = 89
so 89 is the third interior angle of the triangle. now let's find the exterior angle.
you know that the extended angle is supplementary; which means it will equal 180° as well. so lets add the third interior angle we just found and let's add it to the unknown expression:
89 + 97 + x = 180
186 + x = 180
-186 -186
x = -6
now it might seem wrong because x is negative and it feels like it should be positive. but let's check our answer.
64+27+89 does equal 180
and 97+(-6)+89 does equal 180
i hope this helps!

How many inches are in 4 1/2 yards of fabric?
Answers
Answer: 162 inches
Step-by-step explanation: 4 yards are 144 inches and 1 yard alone is 36 when you divide it by half it’s 18. (144+18=162)
To convert [tex]4 \dfrac{1}{2}[/tex] yards of fabric to inches, multiply by 36.
Therefore, there are 162 inches in [tex]4 \dfrac{1}{2}[/tex] yards.
For the measurement, we know
1 yard = 36 inches
The given measurement is: [tex]4 \dfrac{1}{2}[/tex] yards
Convert it into an improper fraction,
[tex]4\dfrac{1}{2} = \dfrac{4 \times 2 + 1}{2} \\\\ = \dfrac{9}{2}[/tex]
Thus, [tex]4 \dfrac{1}{2}[/tex] yards can be written as [tex]\dfrac{9}{2}[/tex] yards.
Since 1 yard = 36 inches
Therefore,
(9/2) yards = (9/2)x36 inches
= 9 x 18 inches
= 162 inches
Hence,
The measurement [tex]4 \dfrac{1}{2}[/tex] yards are equivalent to 162 inches.
