Answer:
Since -15/16 does not equal -16/15, the statement is verified/true.
Step-by-step explanation:
Plug in the numbers for the variable:
-3/4 ÷ 4/5 =/ 4/5 ÷ -3/4
Copy dot flip:
-3/4 × 5/4 =/ 4/5 × -4/3
Multiply numerators and denominators separately:
-3 × 5 / 4 × 4 =/ 4 × -4 / 5 × 3
-15 / 16 =/ -16/15
-15/16 =/ -16/15
-15/16 does not equal -16/15.

Answer:
89*
Step-by-step explanation:
To find the value of m<1, you need to find the angle right next to it (the third interior angle that isn't labeled).
To find that angle (let's call it x), we have to use an equation.
Since a triangle has a sum of 180* for the interior angles in it, then we can use that to solve for x.
x + 53 + 36 = 180
x + 89 = 180
x = 91
Now to find m<1, we need to use the supplementary angles theorem.
Since m<1 and x are supplementary angles, the sum of those angles would be 180. Using this, we can create an equation.
x + m<1 = 180
91 + m<1 = 180
m<1 = 89
Hence, m<1 is 89*!

Answer:
x = 46.7°
Step-by-step explanation:
We are given:
1.) Angle x
2.) Side opposite to angle x
3.) Hypotenuse
We have to find angle x, therefore Sin ratio would be used;
Sin(x) = Opposite / hypotenuse
Sin(x) = 4 / 5.5
x = Sin⁻¹(4/5.5)
x = 46.7°

The width of a rectangle measures (3s+t) centimeters,and it’s length measures (3s-9t) centimeters. Which expression represents the perimeter,in centimeters of the rectangle ?
Answer:
12s - 16t
Step-by-step explanation:
2(3s + t) + 2(3s - 9t)
6s + 2t + 6s - 18t
12s + 2t - 18t
12s - 16t
Answer:Perimeter of the rectangle =(12s -16t)centimeters.
Step-by-step explanation:
The perimeter of a rectangle is given as 2(l+w)
Given that width of the rectangle=(3s+t)centimeters. and
Length of the rectangle=(3s-9t)centimeters.
Solving we have
Perimeter= 2(l+w)
Perimeter=2(3s+t +3s-9t)
Perimeter=2(3s+3s -9t+t)
Perimeter=2(6s-8t)
Perimeter=(12s -16t)centimeters.

determine the level in decibels of a sound that has an intensity I = 10^-6 watts/cm2
Answer:
The level in decibels is 100.
Step-by-step explanation:
The intensity level in decibels (β) can be found using the following equation:
[tex] \beta = 10log(\frac{I}{I_{0}}) [/tex]
Where:
I: is the intensity = 10⁻⁶ W/cm²
I₀: is the reference intensity = 10⁻¹² W/m²
First, we need to convert the unit of the given intensity from W/cm² to W/m².
[tex] I = 10^{-6} \frac{W}{cm^{2}}*\frac{(100 cm)^{2}}{1 m^{2}} = 10^{-2} W/m^{2} [/tex]
Hence, the level in decibels is:
[tex] \beta = 10log(\frac{10 ^{-2} W/m^{2}}{10^{-12} W/m^{2}}) = 100 dB [/tex]
Therefore, the level in decibels is 100.
I hope it helps you!
Triangle congruence geometry
Answer:
Not necessarily
Step-by-step explanation:
The triangles have two sides congruent to each other (BA and RA/BE). They also have angles BRA and BEA congruent, but these do not fit into any of the congruency theorems (SSS, SAS, ASA, or AAS).
A company is designing a new logo that is comprised of four identical sectors of circles that have central angles
that measure 30º. A portion of the logo is shaded. The distance from the center, C, to point A is 8 inches
and the distance from point A to point B is 3 inches.
Determine the area of the logo that is shaded to the nearest tenth of a
square inch. Show the work that leads to your answer.
============================================================
Explanation:
The radius of the larger circle is CB = CA+AB = 8+3 = 11 inches.
The area of the larger circle with this radius is...
A = pi*r^2
A = pi*11^2
A = 121pi
The area of the smaller circle (radius CA = 8 inches) is
A = pi*r^2
A = pi*8^2
A = 64pi
The difference is 121pi-64pi = 57pi
This represents the exact area of the full ring. Refer to figure 1 below. Specifically the red region of that figure.
However, we don't want the full ring. We only want a small fraction of it (as figure 2 shows, which is the original diagram your teacher gave you). Specifically, we want (4*30)/360 = 120/360 = 1/3 of the full ring. The 4*30 refers to the idea we have four copies of the 30 degree angle.
So we'll take 1/3 of the 57pi to get (1/3)*57pi = (57/3)pi = 19pi
-----------------------------------
The value 19pi is the exact area of the entire shaded region.
From here, you can use a calculator to determine that
19pi = 19*3.1415926535898 = 59.6902604182061 which rounds to 59.7
If your teacher insists you use pi = 3.14, then 19*pi = 19*3.14 = 59.66 which also rounds to 59.7

The trapezoid is enlarged by a scale factor of 3, what is the area of the scaled copy?
Answer:
Step-by-step explanation:
After enlargement,
Parallel sides are: 6*3 = 18 cm & 10*3 = 30cm
Altitude = 5 *3 = 15 cm
Area =[ (sum of the length of parallel sides)*height] ÷2
[tex]= \frac{(18+30)*15}{2}\\= \frac{48*15}{2}\\\\= 24 *15\\\\= 360[/tex]
Answer:
360 cm²
Step-by-step explanation:
The area (A) of the trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ are the parallel bases
Here h = 5 , b₁ = 10, b₂ = 6 , then
A = [tex]\frac{1}{2}[/tex] × 5 × (10 + 6) = 2.5 × 16 = 40 cm²
Enlarging by a scale factor of 3 means the area is increased by a factor
3² = 9
area of scaled copy = 9 × 40 cm² = 360 cm²

A chair rental company charges $100 for delivery plus $3 per chair.
Write an explicit function for the total cost, T(c), of renting c number of
chairs.
Answer:
T(c) = 100 + 3*c
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
T(c) = 100 + 3*c
Answer:
T ( c)= $ 100 + $ 3 c
Step-by-step explanation:
Given that :-
Fee for delivery = $ 100Cost per chair = $ 3No. of chair = cTo Find :-
Total cost T( c) of renting c no. of chairs.Solution :-
Total Cost, T ( c) = Fee + cost per chair × no. of chairs.
T ( c) = $ 100 + $ 3 × c
T ( c) = $ 100 + $ 3 c
