Answer: 0.04
Step-by-step explanation:
The measurement error is calculated as:
= Error / Ideal value
= (2.5 - 2.4) / 2.5
= 0.1/2.5
= 0.04
Therefore, the correct option is D.

Answer:
x =4 hours
Step-by-step explanation:
We can use ratios to solve
26 quizzes 104 quizzes
----------------- = -------------------
1 hour x hours
Using cross products
26x = 1 * 104
26x = 104
Divide each side by 26

The calculated length of V'B' in the reflection of triangles is (c) 5
How to determine the length of V'B'From the question, we have the following parameters that can be used in our computation:
The triangle and the image
Also, we know that the triangles are reflected
The reflection transformation is a rigid transformation
This means that
V'B' = VB
From the figures, we have
VB = 5
So, we have
V'B' = 5
Hence, the length of V'B' is (c) 5

Consider points R, S, and T.
Point S is in the middle. Point R is below and to the left of point S. Point T is below and to the right of point S.
Which statement is true about the geometric figure that can contain these points?
No line can be drawn through any pair of the points.
One line can be drawn through all three points.
One plane can be drawn so it contains all three points.
Two planes can be drawn so that each one contains all three points.
Answer:
one plane can be drawn so it contains all three points for this question.

How to solve this geometry?
Step by step solution please.
This is a relatively complex problem and it took me a good 20 minutes to solve, I included a sketch I made myself while im solving this problem hope it helps with the explanation. (the dotted lines are my drawings, also I labeled the points just look at my graph)
Now to find <x, we can use the exterior angles theorem a couple of times.
<x=<p+<AGE
<x=30 degrees + <AGE
Now use the theorem again to find <AGE
<AGE=<q+<BIG
Now use substitution for <q and for <AGE
<x=30 degrees+60 degrees+ <BIG
We put this to the side for now and try solve for <CHD which is not very difficult
<CHD=180-45-20=115
We can also clearly figure out <HFI using vertical angles theorem.
<HFI=<Y
Because they all form a triangle we can conclude that <y+<BIG=180 degrees-<FHI= 180-115=65 degrees
substitution again
<x+<y=30+60+<BIG+<HFI (remember <HFI = <y vertical angles theorem)
<x+<y=30+60+65 (remember how we did before these 2 angles adds up to 65?)
<x+<y=155 degrees
Now please don't hate me on this, I'm sure there is more efficient ways to explain this problem, this is just my way from trial and error.
Tip for next time you are stuck on a geometry problem, don't be afraid to draw the graph again on paper and add lines to it!
You won't get everything perfect the first time you try but the more you practice the more comfortable you are with these problems, Hope my explanation helped!

Question 9
Which of the following is a point on the equation for 3x + y = 4.
What is the image of the point (9,7) after a rotation of 180 counterclockwise about the origin
The image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.
Rotation of a point A(x, y) 180 counterclockwise about the origin produces an image at A'(-x, -y).
Hence, the image of the point (9,7) after a rotation of 180 counterclockwise about the origin is at (-9, -7)

Answer:
Step-by-step explanation:
∠A + ∠B + ∠C = 180 {Angle sum property of triangle}
∠A + 65 + 55 = 180
∠A + 120 = 180
∠A = 180 - 120
∠A = 60
If two triangles are similar, then the corresponding angles of two triangles are congruent.
z = ∠A
z = 60
In ∆ ABC,
[tex]\angle[/tex] A + [tex]\angle[/tex] B + [tex]\angle[/tex] C = 180° .... (Angle sum property of a triangle)
Here, we have:
[tex]\angle[/tex] B = 65°[tex]\angle[/tex] C = 55°Substituting values,
[tex]\dashrightarrow\sf{\angle A + 65 + 55 = 180} \\ \\ \dashrightarrow\sf{\angle A + 120 = 180} \\ \\ \dashrightarrow\sf{\angle A = 180 - 120} \\ \\ \dashrightarrow{\boxed{\sf{\gray \angle A = 60 \: \bigstar}}}[/tex]As we know that,
★ If two triangles are similar, then the corresponding sides of two triangles are congruent.

What’s the volume of the prism ?
Answer:
63[tex]cm^{3}[/tex]
Step-by-step explanation:
To find the volume of this prism, all you need to do is multiply the height, the width, and the length of the prism. The height is 3, the length is 7, and the width is 3. So 3·3·7=9·7=63. Now we have to add the label, which is cm. We are multiplying 3cm by 3cm by 7cm, which makes it [tex]cm^{3}[/tex]. Now you just multiply [tex]cm^{3}[/tex] and 63 together, which gets you 63[tex]cm^{3}[/tex].

∠A and \angle B∠B are complementary angles. If m\angle A=(x+16)^{\circ}∠A=(x+16) ∘ and m\angle B=(x-12)^{\circ}∠B=(x−12) ∘ , then find the measure of \angle A∠A.
Answer:
Step-by-step explanation:
∠A + ∠B = 90 {∠A & ∠B are complementary}
x + 16 + x - 12 = 90
x + x + 16 - 12 = 90 {Combine like terms}
2x + 4 = 90 { Subtract 4 form both sides}
2x = 90 - 4
2x = 86 {divide both sides by 2
x = 86/2
x = 43
A colony of 1,000 bacteria doubles in size every 18 minutes. What will the population be 54 minutes from now? (show steps) - will give brainliest
Answer:
3000.24
Step-by-step explanation:
We know that every 18 min, the colony grows 1000, so to make it easy, the way i do it is that i find out how much it grows per min
1000 / 18 = 55.56
Then, to find out how big it will be in 54 min, we just multiply
55.56 x 54 = 3000.24
So that will be the size of the colony in 54 min. I hope this helps :)
