Answer:
z = -11
Step-by-step explanation:
-5Z = 55
to find z, divide each side by -5
[tex]\frac{-5Z}{-5} = \frac{55}{-5}[/tex]
z = -11
Answer:
Z = -11
Step-by-step explanation:
When dealing with variables, you want to get it alone so it instantly equals the number.
Since Z is being multiplied by -5, you're going to divide -5 because that's the opposite of multiplying--but you have to do it on both sides, not just the one.
Note that when you're dividing or multiplying a negative and positive number, the result with ALWAYS be negative!
-5Z = 55
/-5 /-5
Z = -11
Just in case, we'll plug in -11 for Z and see if it works.
-5(-11) = 55
Note again that when you're multiplying two negatives it cancels out the negative and makes the answer positive!

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 :)
it says Andre starts with $100 in his savings account and adds $5 per week Elena starts with $10 in her savings account and adds $20 each week after 4 weeks who has more money in their savings account
Answer:
Andre
Step-by-step explanation:
So for Andre you would do 5*4=20 and 100 + 20 = 120.
And Elena you would do 20*4=80 then 80 + 10 = 90.

Step-by-step explanation:
∠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
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

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].

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

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!
