Answer:

a: 42%

b: 68%

Step-by-step explanation:

Answer:

1. The probability of selecting a senior is 0.42 (42%).

2. The probability of not selecting a freshman is 0.68 (68%).

Step-by-step explanation:

Total students: 19

1. [tex]\frac{8}{19} = 0.42[/tex]

2. [tex]\frac{13}{19} = 0.68[/tex]

Answer:

What I understand is that I need to give someone an exact number so that when 30% is taken, they keep exactly 35,000

To make the statement above true, we would need to divide 35,000 by 7 since the answer would be 10% of the number we need. Once we do this we get 5000 which is 10% now we multiply 5000 by 10 to get 100% and we get 50.000 once we give this amount to the person and 30% is taken away they are left with 35,000

Answer: 10

Step-by-step explanation:

Answer:

x = 10

Step-by-step explanation:

[tex]14x - 38 = 2(51)[/tex]

[tex]14x - 38 = 102[/tex]

[tex]14x = 102 + 38[/tex]

[tex] \cfrac{14x}{14} = \cfrac{140}{14} [/tex]

[tex]x = 10[/tex]

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The figure of triangle is shown.

Here, The length of perpendicular distance = x mm

And, The hypotenuse = 178 mm

Hence, We get;

⇒ sin 34° = x / 178

⇒ 0.72 = x/178

⇒ x = 0.72 × 178

⇒ x = 128.2 mm

Answer: y=0.95x+8.35

Step-by-step explanation: Hi there.

We can use the equation y=mx+b, where

y=the result (in this case the cost of the pizza)

m=the slope (how much each topping costs)

x=input value (how many kinds of toppings the pizza has)

b=initial value (how much the plain pizza costs)

The toppings cost $0.95, and the value of the plain pizza is $8.35

So the equation is: y=0.95x+8.35.

Have a nice day! :)

Answer:

y= -2

Step-by-step explanation:

The line y = -2 is half way between the 2 shapes (there are 3 squares between the line).

If you were to have a mirror and place it down this line, you would be able to see that the shapes are reflected in the exact same place.

I have attached a photo to help demonstrate what y= -2 looks like :)

Hope this helps!

Answer:

y=-1

Step-by-step explanation:

The line of reflection is y = -1

Answer:

70

Step-by-step explanation:

There are 6 numbers that end with 0 and are between 50 and 100 : 50,60,70,80,90,100. And only 70 is the multiple of 7, so 70 is the number.

The truss bridge should depict a congruent triangle by having equal sides and angles.

It should be noted that the congruence of a triangle simply means that a triangle that has all the three corresponding sides to be equal.

In this case, after designing the truss bridge model, it's important that the sides of the model are equal. Also, the corresponding angles of the model have to be equal too.

Applying the Pythagorean theorem, the length of the altitude is: 7.79 units.

The Pythagorean Theorem is given as: c² = b² + a², where c is the hypotenuse.

An altitude of an equilateral triangle bisects the base of the triangle forming equal segments. Therefore, we would have the following:

c = 9

b = 4.5

Length of altitude = a = ?

Thus:

a = √(c² - b²)

a = √(9² - 4.5²)

a = 7.79 units.

Thus, applying the Pythagorean theorem, the length of the altitude is: 7.79 units.

Answer:

Step-by-step explanation:

Angle 5 is opposite to 37 => It's equal to 37.
Angle 6 and 7 are supplementary to angle 5 => They are equal to 180 - 37 = 143 each.

Angle 4 is corresponding to Angle 7, and since the 2 lines are parallel, it's equal to 143.

Angle 1 and 3 is supplementary to Angle 4, so they are equal to 180-143 = 37 each

Angle 2 is opposite to Angle 4, so it's equal to 143.


Answer : Angle 1,3,5 = 37
Angle 2,4,6,7 = 143

Answer:

Answer:

Difference of volume of air = [tex]17182.08cm^{3}[/tex]

Step-by-step explanation:

Radius of ball = 18 cm

Volume of big ball = [tex]\frac{3}{4} \pi o^{3}[/tex]

                               = 4/3 x * 14 X 18[tex]^{3}[/tex]

                               = 7324g * g2/ 3

                               = 24416.64cm^3

Radious of another (small ball) = 12 cm

Volume of small ball = [tex]\frac{3}{4} \pi R^{3}[/tex]

                                  = 4/3 x 3 * 14 X 12^3

                                  = 21703.68/ 3

                                  = 7234 * 56cm^3

Difference of volume = [tex]v_{b} -v _{s}[/tex]

                                   = 24416 * 64 -  7234 * 56cm^3

Answer:

7/8

Step-by-step explanation:

She used 29.8 feet of fencing for the fence -> The circumference of the circular garden is 29.8ft

Formula for circumference : 2πr

So, the radius is equal to : 29.8 : 2 : π = 4.74281730414... (round to 4.7)

Recheck : 4.7 x 2π = 29.5309709437... (close to 29.8)

Answer:

x = 4[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2x = 8[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

x = 4[tex]\sqrt{3}[/tex]

Answer:

m1 = 44 m2 = 46

Step-by-step explanation:

On the opposite side of the 1, there is a 44

Step-by-step explanation:

V=1/3 πr²h

700 π=1/3 πr²×21

r²=100

r=√100=10 units

Answer:

r = 10

Step-by-step explanation:

Using the formula:

[tex]V = \pi r^{2} \frac{h}{3}[/tex]

We make r the subject to get:

[tex]r = \sqrt{3 \frac{V}{\pi h} }[/tex]

Now we substitute values given and simplify:

r = [tex]\sqrt{3 \frac{700\pi }{21\pi } }[/tex]

We can cancel out pi from top and bottom:

r = [tex]\sqrt{3 \frac{700 }{21 } }[/tex]

We can do 700÷21 = 33.3333333333

Now we have:

[tex]r = \sqrt{3 *33.3333333333}[/tex]
Simplify to get :

r ≈ 10
