Hello! I would love to help you on your question!

Alright. Let's start by finding the total amount of students in Mr. Ernesto's club.

We know he has 7 sixth graders

He has 9 seventh graders.

He has 4 eighth graders

So, let's add those all up!

7+9+4=20

Okay, we know there are 20 students in the club now!

Of those 20, we know 12 have microscopes.

We can write this as a fraction: 12/20

Let's reduce that down to 3/5.

Last step!!! We're almost done!

Divide 3 by 5 on a calculator or using long division

3/5=0.6

Convert that into a percentage by doing 0.6*100

That is 60.

So, your answer is 60 percent (%) of the students own microscopes!

Hope this helped! Comment if you have any questions! :)

I need to find the area of a semicircle with a radius of 2 units
MariettaO [177]

Answer:

6.2832 square units (rounded off to four decimal values)

Step-by-step explanation:

Area of a semicircle = \frac{1}{2} × π × r²

r (radius) = 2 units

For our semicircle the area = \frac{1}{2} × π × 2² = 6.28318530718  square units

Or 6.2832 square units (rounded off to four decimal values)

Write the equation of the line in point-slope form that passes through (5, -1) and has a slope of 2/3
kolezko [41]

Answer:

y-(-1)=2/3(x-5)

Step-by-step explanation:

Point slope form is

y-y_1=m(x-x_1) where m is the slope, x_1 is the x coordinate of a point that the line passes through, and y_1 is the y coordinate of a point the line passes through.

Substituting, we get

y-(-1)=2/3(x-5)

Please Help:<br> In Δ ABC, sin A= 88, sin B= 42, and a =17 , find the length of b.
enyata [817]

Answer:

11.4 units

Step-by-step explanation:

a/sinA = b/sinB

17/sin(88) = b/sin(42)

b = sin(42) × 17/sin(88)

b = 11.3821540088
