69 out of 100 would be 69/100 = 0.69 = 69% were answered correctly
100% - 69% = 100-69 = 31 = 31% = 31/100 were incorrect
I think the question is missing some details. I found a similar question with an image as i attached in this question.
From this image, it its clear that m1, m2 and m3 refers to the angles in the middle of the rhombus
Answer:
x = 9
y = 81
z = 5
Step-by-step explanation:
Note that in rhombus, all sides are the same. If the diagonal lines are made, it will create 4 division of angles of 90 degrees.
Therefore m1 = m2 = m3 = 90 degrees
m1 = 10x and m1 =90
So, 10x = 90. Rearrange it to get x = 90/10 = 9
x = 9
m2 = x + y and m2 = 90
So, x + y = 90
9 + y = 90
y = 90 - 9 = 81
m3 = 18z and m3 = 90
So, 18z = 90
z = 90/18 = 5
The answer is 10.6 cubic inches.
The formula for a volume of the cone is V = 1/3 π r² h,
where:
V - the volume of the cone,
<span>r - radius of the cone base,
</span>h - height of the cone.
It is given:
h = 4.5 in
r = 1.5 in.
π = 3.14
If:
<span>V = 1/3 π r² h,
</span>Then:
V = 1/3 × 3.14 × (1.5 in)² × 4.5 in
V = 1/3 × 3.14 × 2.25 × 4.5 in³
V = 10.6 in³
Therefore, Judy's sugar cone can hold 10.6 <span> in³.</span>

Step-by-step explanation:
Answer: x = 4 / 2y-z
Step-by-step explanation: Move all of your terms to the left and then set your equal as 0. Then, set each of your factors equal to 0, as well.
I hope this helps you out.
