The answer is A) 1:2, because there are 80 blue marbles and 40 red marbles, (for a total of 120 marbles) and the ratio 40:80 simplifies down to 1:2.

<h3>Answer: Choice B</h3>

Angle 1 = 147 degrees

Angle 2 = 80 degrees

Angle 3 = 148 degrees

======================================================

Work Shown:

(angle 1) + 33 = 180

angle 1 = 180-33

angle 1 = 147 degrees

---------------

Focus on the left most triangle that has angles 33 and 47 as interior angles. The missing angle is 180-33-47 = 100 degrees

The angle exterior to this 100 degree angle is angle 2

angle 2 = 180-100 = 80

We have enough info to conclude the answer must be choice B.

---------------

Let's keep going to find angle 3

The vertical angle for the 100 degree angle is also 100 degrees. This second 100 degree angle is part of the triangle on the right

This triangle on the right has interior angles 100 and 48

The missing interior angle is 180-100-48 = 32

The angle supplementary to this is 180-32 = 148, which is angle 3.

The rear windshield wiper blade on a car has a length of 11 inches. The blade is mounted on a 15 inch arm, 4 inches from the piv
vekshin1

Answer:

246.22\ \text{inches}^2

Step-by-step explanation:

r_1 = Radius of arm = 15 inch

Length of blade = 11 inches

r_2 = Radius of point at which the blade is mounted = 4 inches

\theta = Angle of the sector = 135^{\circ}

The required area is ABDE

ABDE=ACE-BCD\\\Rightarrow ABDE=\dfrac{\theta}{360^{\circ}}\pi r_1^2-\dfrac{\theta}{360^{\circ}}\pi r_2^2\\\Rightarrow ABDE=\dfrac{\theta}{360^{\circ}}\pi(r_1^2-r_2^2)\\\Rightarrow ABDE=\dfrac{135^{\circ}}{360^{\circ}}\pi(15^2-4^2)\\\Rightarrow ABDE=246.22\ \text{inches}^2

The area which is swept clean is 246.22\ \text{inches}^2

Amplifica fractia 2 supra 5 pana cand numitorul o sa fie 100
Savatey [412]

Answer:

Step-by-step explanation:

Fractia 2 supra 5 trebuie sa fie egala cu fractia care are numitorul 100

2/5 =  x /100

Cu cat e 100 mai mare decat 5 ?

5 ·? = 100

    ? = 100/5 = 20

Amplifica fractia care ti s-a dat 2/5 cu 20  

2·20 /5·20 = 40 /100
