PLS HELP ASAP. QUESTION IN PICTURE
Anuta_ua [19.1K]

Answer: 50 degrees

Step-by-step explanation:

This is actually quite simple using the exterior angle theory

"The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle"

In this case the exterior angle is 120 degrees, basically what the theorem states is that it the angle that you see outside the triangle equals the angle measurements of the 2 angles opposite of it, so just create an equation because you know 2 of the variables

120=70+x

120-70=x

Angle x = 50 degrees

John wants to nail a thumbtack on his circular board, pictured below. If the thumbtack is equally likely to be placed anywhere o
Nikitich [7]

Answer: A. 51%

Step-by-step explanation:

Area of circle = \pi r^2 , where r = radius of the circle.

In the figure below, we have the complete question.

According to that,

Radius of outer circle = 7ft

Radius of inner circle = 5ft

The probability that the thumbtack will be placed on the inner circle

=\dfrac{\text{Area of inner circle}}{\text{Area of outer circle}}\\\\=\dfrac{\pi (5)^2}{\pi (7)^2}\\\\=\dfrac{25}{49}[π is canceled from numerator and denominator

in percent, \dfrac{25}{49}\times100=51.0204081633\%\approx51\%

So, the probability that the thumbtack will be placed on the inner circle = 51%

Hence, the correct option is A. 51%.

Bao is mixing flour and water to make dough. The graph shows how much water he uses for different amounts of flour.
Butoxors [25]

Answer:

0.33 liters of water Bao use per liter of flour.

3  liters of flour Bao use per liter of water

Step-by-step explanation:

Given the graph which pass through the coordinates (0,0) and (3,1)

∴ Equation of line passing through these points can be written as

(y-y')=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x')

⇒  (y-0)=\frac{1-0}{3-0} (x-0)

⇒ y=\frac{1}{3}x ⇒ 3y=x

Now, we have to find liters of water Bao use per liter of flour i.e if x=1 then we find the value of y which is 3y=x=1 ⇒ y=\frac{1}{3} = 0.33 l

Now, we have to find  liters of flour Bao use per liter of water i.e if y=1 the we have to find the value of x which is x=3 litre
