How do I find what AC is?

Answer:

Step-by-step explanation:

0.40beta%2Bbeta=180-5

1.40beta=175

beta=175%2F1.40

highlight%28beta=125%29�

then alpha%2B125=180 =>alpha=180-125 =>highlight%28alpha=55%29

The required values of angles are 125 and 55.

When two straight lines come together at a point, they produce an angle, which is represented by the symbol.

Given that,

Two angles are supplementary to each other.

Let angles are α and β.

According to given condition,

α + β = 180      (1)

Also, the measure of one angle α is 5 greater than 40% of the other.

α = 0.4 β + 5      (2)

Substitute the value of α in equation (1),

0.4 β + 5 + β = 180

1.4 β = 175

β = 175 / 1.4 = 125

The value of α =0.4 x 125 + 5 = 50 + 5 = 55

The value of angle α and β are 125 and 55.

Answer:

30 m

Step-by-step explanation:

Total length of pipe = 150 m

Central heating system = 20% of 150 m

= 0.2 × 150

= 30 m

Length of pipe remaining = 150 m - 30 m

= 120 m

Bathroom fitting = 25% of 120 m

= 0.25 × 120

= 30 m

The plumber used 30 m of pipe to fit the bathroom

Answer:

Step-by-step explanation:

3 ( x - 3 ) = 5x - 4 + 3 ( 7 - x )

3x-9 = 5x-4 + 21 - 3x

collect like terms

3x-9 = 2x +17

move the terms

3x-2x = 17+9

x=26

Answer:

26

Step-by-step explanation:

3 (x-3) = 5x - 4 + 3 (7-x)

3x - 9 = 5x - 4 + 21 - 3x

3x - 9 = 5x - 3x + 17

3x - 9 = 2x + 17

3x - 2x = 17 + 9

x = 26

Answer:

150120.83 ; 40 ; 1800

Step-by-step explanation:

Amount of share per person = x

Number of persons = y

x = k/y

k = constant of proportionality

k = xy

257,350 * 7 = 1801450

k = 1801450

If there are 12 persons ; y = 12

x = k/y

x = 1801450 / 12

x = 150120.83

2.) weight on Mars = m

Weight in earth = e

m α e

m = ke

48 = 120k

k = 48 / 120

k = 0.4

m = 0.4 * 100

m = 40

3.)

I α pt

I = kpt

600 = k * 10000 * 2

600 = 20000k

k = 600/20000

k = 0.03

I = 0.03 * 15000 * 4

I = 1800

Answer:

If we add up all the angles of any triangle, we should get 180 degrees. Therefore, Angle C = 90 (angle A) - 45 (angle B) = 45 degrees. Since there was a ray drawn from A through C the exterior angle of angle C is angle 1.

Step-by-step explanation:

a "one angle" A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. ... Because a full rotation equals 2π radians, one degree is equivalent to π180 radians.

[tex]0.0633[/tex] is the the probability that the 6th pizza ordered is the first extra-large pizza.

What is probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

According to question, at a certain pizzeria, it is known that 12% of orders are for extra-large pizzas.

We have to find, what is the probability that the 6th pizza ordered is the first extra-large pizza.

Probability of extra-large pizzas [tex]=\frac{12}{100}[/tex][tex]=0.12[/tex]

Probability of other pizzas[tex]=1-0.12=0.88[/tex]

Hence, the probability that the 6th pizza ordered is the first extra-large pizza[tex]=0.88^{5}[/tex]×[tex]0.12[/tex](since first 5 pizzas are other pizza)

        [tex]=0.527[/tex]×[tex]0.12[/tex]

        [tex]=0.0633[/tex]

Hence, we can conclude that [tex]0.0633[/tex]   is the probability that the 6th pizza ordered is the first extra-large pizza.

have a great day (:

angle 1 = 180-110 = 70 degrees (linnear pair)

angle 2= 180-115 = 65 degrees (linnear pair)

angle 3 = angle 2 = 65 degrees (corresponding angles)

angle 4= 180 - angle 3 = 180-65 = 115 degrees (linnear pair)

(your teacher might not like this, depends on the cituation, but use 180 degrees in triangle to get 7)

angle 7 = 180 -angle1 -angle 2= 180-70-65= 45 degrees

angle 6 = angle 7 = 45 degrees ( vertical angles)

angle 8= 180- angle 7= 180-45 = 135 ( linnear pair)

angle 9 =angle 6 = 45 degrees (corresponding angles)

angle 5=angle 9=45 degrees (vertical angles)

The measure of angle A to the nearest degree.

Solution:

We have,

[tex]\cos \angle A=\dfrac{342}{1000}[/tex]

The answer is x=6, y=3

Step-by-step explanation:

Multiply each equation by the value that makes the coefficients of y opposite(−1)⋅(4x−7y)=(−1)(3)x−7y=−15

Simplify.

−4x+7y=−3x−7y=−15

Add the two equations together to eliminate y from the system.−4x+7y=−3+x−7y=−15−3x=−18

Divide each term by −3 and simplify.

x = 6

Substitute the value found for x into one of the original equations, then solve for y.

y = 3

The solution to the independent system of equations can be represented as a point.(6,3)

The result can be shown in multiple forms.

Point Form: (6,3)

Equation Form: x=6, y=3
