In the triangle below, find the measurements of the unknown angles. A. 75º, 105° B. 40°, 80 c. 5° 10° D. 250 50 E. 35°, 70​

Answer:

boys = 705

girls = 783

Step-by-step explanation:

We are to find the number of boys and girls in the school

the answer can be determined using simultaneous equation

x = boys

y = girls

y - x = 78  equation 1

y + x  = 1488 equation 2

subtract equation 1 from 2

2x = 1410

x = 1410/2 = 705

Substitute for x in equation 1

y - 705 = 78

y = 705 + 78 = 783

Answer:

The top one is refraction

Refraction is the bending or change in angle of light

Hope this helps (sorry I don’t have the answer to the second question)

Answer:

1. Refraction

2. Translucent  

Step-by-step explanation:

1. Refraction is the bending of light

2.Translucent Materials are materials that allow light to pass through them. Opaque materials do not allow light to pass through them.

Answer:

El valor de cada cuota fija es de $500.

Step-by-step explanation:

Para encontrar el valor de cada cuota fija, puedes calcular la diferencia entre lo que Juan ha pagado y el valor que costó el plasma para saber cuál es el monto que aún debe. Después, debes dividir la cantidad que aún debe pagar entre tres que es el número de cuota pendientes para encontrar el valor de cada cuota teniendo en cuenta que son fijas:

8000-6500=1500

1500/3=500

De acuerdo a esto, la respuesta es que el valor de cada cuota fija es de $500.

A=250

r= 15%

Step-by-step explanation:

Given data

We have the function

y = 250(.85)^6------------1

The given function is the same as the exponential decrease

function

P=A(b)^t---------------------2

Note

b= 1-r= 1-0.15

b= 0.85

When we compare both 1 and 2 above

A=250

r= 15%

Answer:

the answer is A. y=2sin(1/2x)+1

Step-by-step explanation:

I input all four functions on desmos (a graphing calculator), and saw that A. y=2sin(1/2x)+1 was similar to the function shown in the graph

The function that matches the graph is y= 2 sin(1/2x) +1.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given:

let y = A sin ([tex]\omega[/tex]x + Ф)+  k

T= 4π, w= 2π/T = 1/2

Now, midline= 1/2( max + min)

=1/2(3-1)= 2/2

k=1

and, A= 3-1 = 2

So, y= 2 sin(1/2x  + Ф) +1

as, Ф=0

So, y= 2 sin(1/2x) +1

Answer:

x = 98

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720

x + 50 + 140 + 112 + x + x + 4 + 120 = 720, that is

3x + 426 = 720 ( subtract 426 from both sides )

3x = 294 ( divide both sides by 3 )

x = 98

Answer:

83%

Step-by-step explanation:

Answer:

72°

Step-by-step explanation:

The full plate has a central angle of 360°.

7/35 × 360° = 72°

Answer:

72°

Step-by-step explanation:

In order to find the value of the central angle, you must first determine what percentage of the plate was broken.

Since 7 out of the total 35 inches of circumference were broken, you divide 7 by 35 ([tex]7/35[/tex]) and get 0.2, which means 20% of the plate is broken.

Now, knowing that a circle consists of 360°, you need to find 20% of 360.

Use the formula [tex]\frac{percent}{100} =\frac{part}{whole}[/tex] .

[tex]\frac{20}{100}=\frac{x}{360}[/tex]

360 x 20 = 7200

7200 ÷ 100 = 72

x = 72

So, the central angle is 72°.

Hello! 59.2 is our answer

This is because for all the triangles we do 5.4 x 4 = 21.6 then I divide by 2 cause thats the formula when doing triangles so I get 10.8 and sense all the triangle sides our the same I do 10.8 x 4 and get 43.2 then for the bottom side I just have to do 4 x 4 cause thats the formula and get 16 then I add these up so 43.2 + 16 = 59.2 and We get our answer 59.2 Hope this helps!

Step-by-step explanation:

rate of change =change of distance/ change of time

so if you look at the chart you can see these points: (2,50) and (6,150)

change of distance would be 150-50/ change of time which would be 6-2 which equals 100/4 which is 25, the rate of change.

x=4 and x= -4

Answer:

C D F

Step-by-step explanation:

C. 2x²=32

x²=16

x=±4

D.-3x²=-48

-x²=-16

x²=16

x=±4

F.27-5x²=-53

5x²=27+53=80

x²=16

x=±4

Answer:

x = -2.

Step-by-step explanation:

y + 2x = -1

y = -2x - 1

y =1/2x+4

Subtracting the last 2 equations:

0 = -2x - 1/2x - 1 - 4

5 = - 5/2 x

x = 5 / -5/2

=  5 * 2 / -5 = -2.
