Answers

Answer:

Option B

Step-by-step explanation:

Given expression is,

(x² - 18x + 180)

Which is in the form of (ax² + bx + c)

To factorize the given expression, we will split b in two parts [tex]b_1[/tex] and [tex]b_2[/tex] so that,

[tex]b=b_1+b_2[/tex]

And [tex]c=b_1\times b_2[/tex]

If b = 18,

[tex]b_1=10[/tex] and [tex]b_2=8[/tex]

c = 10 × 8 = 80

Therefore, (x² - 18x + 180) = x² - 10x - 8x + 80

                                           = x(x - 10) - 8(x - 10)

                                           = (x - 8)(x - 10)

Option B is the correct option.

Triangle ΔGHI with m∠G = 5°, m∠H = 75° and m∠I = 100°, is reflected across the y-axis to obtain ΔKLM. What is the measure, in degrees, of ∠L?

Answers

Answer:

[tex]\angle L = 100^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]\angle G = 5^{\circ}[/tex]

[tex]\angle H = 75^{\circ}[/tex]

[tex]\angle L = 100^{\circ}[/tex]

Required

Determine the measure of L after reflection across x-axis

When a shape is reflected across an axis, only the coordinates of the shapes is affected; the angles remain unaltered.

In other words, the measures of the angle will not change.

Hence:

[tex]\angle L = 100^{\circ}[/tex]

Step-by-step explanation:

If you have completed [tex]5[/tex] questions, you still have [tex]25-5=20[/tex] more questions to answer. We need to find what fraction [tex]20[/tex] is of [tex]25[/tex], if that makes sense. A fraction is simply a part over a whole. In this case, the part is [tex]20[/tex] and the whole is [tex]25[/tex].

Radius of the circle is 20cm. there are two chords of lengths.
32cm, what will be the dis-
tance of these chords from
the centre of the circle?​

Answers

9514 1404 393

Answer:

  12 cm

Step-by-step explanation:

The distance to the chord is the median of an isosceles right triangle with hypotenuse 20 and leg 16. This 5:4 ratio suggests the other leg of that right triangle would make the ratios 3 : 4 : 5, so is 12.

The chords are 12 cm from the center.

_____

You can, of course, use the Pythagorean theorem. If c is half the chord length and d is the distance to the chord, you have ...

  c² + d² = r²

  16² + d² = 20²

  d² = 400 -256 = 144

  d = √144 = 12 . . . . . cm

Juan thinks that the graph of 6y + 12x = 4 is a line. a. Solve Juan’s equation for y.

Answers

The lines slope is negative 2 so it would be y=-2x+4/6

The equation of the line in the slope-intercept form will be y = 2/3 - 2x.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Juan thinks that the graph of 6y + 12x = 4 is a line.

Solve the equation of the line for y, then we have

6y + 12x = 4

6y = 4 - 12x

y = 4/6 - (12/6)x

y = 2/3 - 2x

The equation of the line in the slope-intercept form will be y = 2/3 - 2x.

Cameron & Brett are trying to sell upper & lower level tickets to two Diamondbacks game to raise money for their club baseball team. They sold 5 lower level & 9 upper level tickets to the first game for a total of $303. They sold 8 lower level & 10 upper level tickets to the second game for a total of $410. How much money did the people pay for lower level & upper level tickets to go to a Diamondbacks game?

Answers

Answer:

30 Lower level tickets

17 upper level tickets

Step-by-step explanation:

Let:

Lower level tickets = l

Upper level tickets = u

5l + 9u = 303 - - - (1)

8l + 10u = 410 - - - - - (2)

Multiply (1) by 8 and (2) by 5

40l + 72u = 2424 - - - (3)

40l + 50u = 2050 - - - (4)

Subtract (3) from (4)

22u = 374

u = 374 / 22

u = 17

Put u = 17 in (1)

40l + 72(17) = 2424

40l + 1224 = 2424

40l = 2424 - 1224

40l = 1200

l = 1200 / 40

l = 30

Answers

Answer:

if you use Newton's 2nd rule:

F = m* a (force = mass * acceleration)

you can rearrange the terms to:

a = F/m (acceleration = Force/mass)

which will let you solve for acceleration.

Mónica ha comprado un CD el dependiente le dice que ha descontado el 20% de su valor siendo ese descuento de $20 cuánto costaba inicialmente el CD

Answers

Answer:

El CD costaba $100 inicialmente.

Step-by-step explanation:

Dado que la información indica que el porcentaje de descuento es 20% y ese descuento tiene un valor de $20, puedes usar una regla de tres para encontrar el valor que representa el 100% que sería el valor inicial del CD dado que el 20% del valor es igual a $20:

20%  →  20

100% →    x

x=(100*20)/20=100

De acuerdo a esto, la respuesta es que el CD costaba $100 inicialmente.

z = 17√2


z = 34√3

Answers

Answer:

Step-by-step explanation:

The first triangle right isosceles. The sides opposite the 45° angles are the same length.

x = 13

By the Pythagorean Theorem, y = 13√2

:::::

Second triangle is 30°-60°-90°. Remember that the sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.

The side opposite the 30° has length 3, so the side opposite the 60° angle is 3√3 and the side opposite the 90° angle is 6.

x = 6

y = 3√3

:::::

The third figure has another 30°-60°-90° triangle. The side opposite the 30° angle is 17, so the side opposite the 60° angle is 17√3 and the side opposite the 90° angle is 2×17 = 34.

x = 17√3

The other triangle is right isosceles.  

z = 34

y = 34√2
