Answer:

1. 112

2. 46

Step-by-step explanation:

When two parallel lines are intersected by a transversal, the alternate interior angles are supplementary. Meaning that their angle measures add up to 180 degrees. Set up an equation and solve for the unknown angle using inverse operations.

$68 + ? = 180\\-68\\\\? = 112$

When two parallel lines are intersected by a transversal, the corresponding angles are congruent, in other words, they have the same angle measure.

$? = 46$

What type of conic is given by the equation 4x^2+9y^2=36

zvonat [6]

Answer:

This is equation of ellipse

Step-by-step explanation:

we are given

$4x^2+9y^2=36$

We can see that right side is 36

so, we can make right side as 1 by dividing both sides by 36

$\frac{4x^2+9y^2}{36} =\frac{36}{36}$

$\frac{4x^2+9y^2}{36} =1$

$\frac{4x^2}{36}+\frac{9y^2}{36} =1$

we can simplify it

$\frac{x^2}{9}+\frac{y^2}{4} =1$

we can rewrite it as

$\frac{x^2}{3^2}+\frac{y^2}{2^2} =1$

now, we can compare it with standard equation of ellipse

$\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2} =1$

we can see that both equations are similar

so, this is equation of ellipse

scZoUnD [109]

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept - (3,0)
y-intercept - (0,12)

Slope: -4
Y-intercept: 12

Mr. Smith offered to stay after school for an extra help session. The day after the

marissa [1.9K]

Answer:

132 students

Step-by-step explanation:

Mr Smith offers to take extra help session for students after school

The day after the help session 11 of his students were talking and found out that only 2 had stayed up for the help session

= 2/11

There were actually a total number of 24 students that stayed

We are asked to find the number of student that Mr Smith teaches throughout the day

Let x represent the number of students that were taught during the day

Therefore, the number of student that Mr Smith teaches during the day can be calculated as follows

2/11=24/x

Cross multiply both sides

2 × x = 24 × 11

2x= 264

Divide both sides by 2

2x/2=264/2

x= 132

Hence Mr Smith teaches 132 students during the day.
