Answer:
Slope = -2/3
Step-by-step explanation:

Noah is trying to draw a triangle with a angle and side lengths
of 4 cm and 6 cm.
.
He uses his ruler to draw a 4 cm line segment.
30°
• He uses his protractor to draw a angle on one end of the line
segment.
ANSWER BOTH QUESTIONS ILL GIVE BRANLIEST AND LOTS OF POINTS .
Noah could draw a triangle with side lengths 4 cm, 6 cm, and approximately 10.39 cm, with angles of 30°, 30°, and 120°.
How to solveYes, there is a different triangle Noah could draw. Since Noah has only drawn one side and one angle, he can create two different triangles using the Angle-Side-Side (A S. S) ambiguity
To find the other possible triangle, we need to calculate the angle opposite the 6 cm side. In this case, the given angle is 30°. Using the sine rule, we can find the sine of the opposite angle (let's call it θ):
sin(θ) / 6 = sin(30°) / 4
sin(θ) = (6 * sin(30°)) / 4
sin(θ) ≈ 0.5
θ ≈ 30°
Since the sum of angles in a triangle is 180°, the other angle in the triangle is:
180° - 30° - 30° = 120°
Now, we can use the sine rule again to find the length of the side opposite this new angle:
x / sin(120°) = 6 / sin(30°)
x ≈ 6 * sin(120°) / sin(30°)
x ≈ 10.39 cm
Therefore, Noah could draw a triangle with side lengths 4 cm, 6 cm, and approximately 10.39 cm, with angles of 30°, 30°, and 120°.

3) In another game, there are 10 marbles in a box. 6 are red and 4 are blue. You
pull one marble from the box, don't put it back, and then pull another marble.
Calculate the following probabilities:
a) Pulling two reds.
b) Pulling two blues.
c) Pulling one of each.
Part (A)
We have 6 red and 4 blue marbles, so 6+4 = 10 total.
The probability of getting red is 6/10 since we have 6 red out of 10 total.
The probability of getting another red is 5/9 because we don't put the first marble back.
The probability of getting two reds in a row is (6/10)*(5/9) = 30/90 = 1/3
Answer: 1/3========================================================
Part (B)
4/10 represents the probability of getting blue on the first try
3/9 represents the probability of getting a blue marble on the second try
We don't put the marble back.
(4/10)*(3/9) = 12/90 = 4/30 is the probability of getting two blues in a row.
Answer: 4/30========================================================
Part (C)
Add up the results of parts (A) and (B)
1/3 + 4/30
10/30 + 4/30
(10+4)/30
14/30
7/15
The result 7/15 is the probability of either getting two reds OR getting two blues (pick one case only). This tells us that 7 out of 15 times we'll have this happen. This must mean the remaining 8 times will have two marbles of different colors.
So 8/15 is the probability of picking one marble of each color.
------
As an alternative, we could also consider it like this
(6/10)*(4/9) = 24/90 = 4/15
This represents the probability of picking red first, then blue next.
Similarly,
(4/10)*(6/9) = 24/90 = 4/15
represents the probability of picking blue first, then red next.
Therefore, 4/15+4/15 = 8/15 is the probability of getting one of each color.
-----
Answer: 8/15Find missing angleeeeeeeeeeeeeeeeeeeeeeee
Answer:
C) 80
Step-by-step explanation:
triangles always add up to 180 degrees, so 80+20=100 the missing angle is 80 degrees

1. Lily spent 4 times as much as her sister Sue. If the girls spent $24, how much did each girl spend?
Answer:
Lily spent $19.20, Sue spent $4.80. Make sure to include the units.
Step by Step:
Lets say Sue is X
4x+x=24
5x=24
x=24/5
x=4.8
So sue spent 4.8.
24-4.8=19.2
Lily spent 19.2
Check: 4(4.8)=19.2
19.2+4.8=24

Answer:
y= -1/2x+4
Step-by-step explanation:
slope = rise/run on the graph. the graph is going down, so it's negative. find where the line intersects the graph at a point and then count the squares up and over until it meets again. the line meets at (6,1), you count up one square and over 2 and it meets again. this gives you your rise/run = 1/2. the y intercept is where the line intersects the y axis. here the y intercept is 4 because the like goes through 4 at the y axis.
