In a class of 40 students, every student take either Biology or Integrated Science, 30 students take Biology, 20 students take Integrated Science and 10 take both Integrated Science and Biology. Illustrate this information on a Venn diagram.

Answers

Answer

20 students will take biology, 10 take Integrated Science and 10 take both

Step-by-step explanation:

With Venn diagrams it's best you work from the inside out. With that in mind we know 10 students take both Biology and Integrated Science. In Biology there are 30 total students including the ones that also take both sciences. So we subtract the ones that take both and get 20 students taking only biology. After that there's 30 students total, subtract that from 40, the total number of students and you get 10, the amount of students who take Integrated Science

A conjecture and the two-column proof used to prove the conjecture are shown.
Given: the measure of angle C B D equals 90 degrees. Prove: triangle A B C is a right triangle. Ray B D extends down and perpendicular from point B on segment B C.

Drag an expression or phrase to each box to complete the proof.

Statement Reason
1. m∠CBD=90° Given
2. ∠ABC and ∠CBD are supplementary. Response area
3. Response area Definition of supplementary
4. m∠ABC+90°=180° Response area
5. Response area Subtraction Property of Equality
6. ∠ABC is a right angle. Definition of right angle
7. △ABC is a right triangle. Definition of right triangle

Answers

Answer:

I took the test

Step-by-step explanation: Linear pair postulate

m<abc + m<cbd =180°

subtraction property of equality

m<abc -90°

All expression and phrase are filled below.

Here,

We have to filled all expression and phrase.

What is right angled triangle?

A right-angled triangle is a triangle, which has one of its interior angles equal to 90 degree.

Now,

Given that;

⇒ m∠CBD = 90 degree ….(i)

We have to prove triangle ABC is right angled triangle.

We can see that the line extends down and perpendicular to the line segment BC at point B.

We can also see that ∠ABC and ∠CBD are supplementary angle.

Hence, We prove as;

Statement Reason

1) m∠CBD = 90 degree ( Given )

2) ∠ABC and ∠CBD are supplementary. ( Because ABD is a line and

∠ABC and ∠CBD are linear

pair)

3). ∠ABC+∠CBD = 180 degree ( Definition of supplementary)

4) ∠ABC+ 90 = 180 degree ( m∠CBD = 90 degree )

5) ∠ABC + 90 - 90 = 180° - 90° ( subtraction property of equality)

∠ABC = 180° – 90° (from (i))

∠ABC = 90 degree

6) ∠ABC is a right angle. ( Definition of right angle)

7) Δ ABC is a right triangle. ( Definition of right triangle)

Therefore, according to definition of right angled triangle,

The triangle ABC is a right angled triangle.

Tyler and Ilan scored 48% of their team’s points in the math

competition. If they scored 84 points, what was the team’s total score?

Answers

Answer:

Tyler and llan scored 24 points.

Explanation:

Another way to state this problem is what is 48% of 50.

"Percent" or "%" means "out of 100" or "per 100", Therefore 48% can be written as

100

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the number we are looking for "n".

Putting this altogether we can write this equation and solve for n

while keeping the equation balanced:

n=48,100 × 50

n = 24,001,00

n= 24

How do i get A and B ?

Answers

Answer:

a=60°

b=300°

Step-by-step explanation:

the triangle is equilateral so all angles are 60 °

a = 60°

b=360 - 60 =300°

Answer:

A is 60°, B is 300°

Step-by-step explanation:

If you look closely, you can tell that this circle is divided into 6 triangles, but there is only one showing. This triangle is 1/6 of the circle.

You can find B by find 1/6 of 360° and subtracting that from 360, (a full circle is 360°)

1/6 of 360° is 60°

360° - 60° = 300°, so B is 300°

Now lets find A. Triangles are 180°. This triangle is obviously an equilateral triangle, so the measurements will all be the same.

180 ÷ 3 is 60, so A is 60°
