Question 10

Jordan is trying to graph the following inequality: y < 2x – 10
He plugs in (0, 0) like this: 0 < -10
He decides that this is true, so he shades the side with (0, 0).
What did Jordan do wrong?

Answers

Answer 1

Answer:

Step-by-step explanation:

"0 < -10" is actually false, so Jordan has shaded the wrong side.

This is based on one of the fundamental laws of algebra:

Consider:

A , B and C form a triangle where ∠ B A C = 90 ∘ . A B = 0.5 mm and B C = 15.4 mm. Find the length of A C , giving your answer rounded to 1 decimal place.

Answers

Answer:

15•4 mm

Step-by-step explanation:

using sine rule

a÷ sinA=c ÷sinC

15•4÷sin90=0•5÷sinC

sinC =0•5 × sin90 ÷ 15•4

C =1•9°

A+B+C= 180

90+B+1•9=180

B= 88•2°

b÷sinB = a÷sinA

b÷sin88•2= 15•4÷sin90

b=sin88•2 ×15•4 ÷sin90

b =15•39

to 1 dp

b =15•4 mm

Caitlin is designing a railing for a set of stairs. The railing will begin at a height of 36 inches and follow the slant of the stairs, which decreases 9 inches for every 12 horizontal inches.

A drawing of the side view of a set of 4 stairs. There are lines drawn to show a railing that is at the highest point of the stairs and labeled 36 inches.

Which function can represent the height, y, of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs?

Answers

Answer:

Since we are given that the railing will begin at a height of 36 inches and follow the slant of the stairs, which decreases 9 vertical inches for every 12 horizontal inches.

Thus the rate of change :  

Rate of change represents the slope of line.

Since we are given that height, y, of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs

And the initial height of the railing was 36 inches .

So,the function which would represent the situation can be shown using equation of line :

y = mx+c

So

c = 36 inches

So, the function :

Hence The function which can represent the height, y, of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs :

Answer:

y= [tex]\frac{72}{5}[/tex] or 14.4

Step-by-step explanation:

[tex]\frac{5}{6}y = 12\\[/tex]

Multiply both sides by 6/5, the reciprocal of 5/6.

[tex]y = 12 * (\frac{6}{5} )[/tex]

Express 12 x (6/5) as a single fraction.

[tex]y = \frac{12 * 6}{5}[/tex]

Multiply 12 and 6 to get 72.

[tex]y = \frac{72}{5}[/tex]

Answer: y=14.4


Step by step:
1) x6 on both sides = 5y=72
2)divide both sides by 5= y=14.4

Test Prep There are 80 marbles in a bag. If 30% of the marbles are green, how many marbles are not green

Answers

Hey there!

Step 1: Calculate percentage

Since 30% of the marbles are green

=> 80 × 30/100

=> 8 × 30/10

=> 240/10

=> 24

So, 24 of the marbles are green

Step 2: Substract 24 from 80

=> 80 - 24

=> 56

Therefore, 56 marbles are not green
