Find the missing length.
a
2.1 cm
2.9 cm
I NEED HELPPPP PLSSSS ITS FOR A MASTERY TEST PLSSSS HELPPPP
Answer:
a = 2
Step-by-step explanation:
To find the missing length we can use the Pythagorean theorem. Also, because it's a right triangle it makes it the perfect candidate!
The Pythagorean Theorem states:
a^2 + b^2 = c^2
Next, we substitute the letters with our given numbers (keep in mind that c is the hypotenuse which is the side facing the right angle)
a^2 + 2.1^2 = 2.9^2
Finally, we solve our equation (hint: use the calculator if needed)
a^2 = 4 (your answer is not final yet. You have to take the square root of both numbers)
a = 2 (Now that's the final answer!)

how does the Torah affect Jewish life today !!!!!!!
i will give brainlisttttt
Answer:
the Torah plays a big part in the lives of Jews today as it is believed to be the word of God. All Jews use the Torah to help guide them in their lives, but some Jews use the Torah more strictly than others. For example, some Orthodox Jews believe that it is important to follow every single rule in the Torah. However, Reform Jews tend to follow the rules they feel are most important and disregard some rules they see as outdated.
The significance of the Torah is seen in many ways:
It is read aloud weekly at the synagogue. It takes a year to recite the whole Torah.
The festival of Shavout celebrates God’s revelation of the Torah to Moses.
The commandments in the Torah shape the way that Jews live their lives today.

Find the the area of a right triangle if 8cm and 12cm are a leg and a hypotenuse. Round to the nearest hundredth.
Answer:
Step-by-step explanation:
The area of a triangle is
A=bh/2 where b=base and h=height. So we first have to solve for h
8^2+h^2=12^2
h^2=12^2-8^2
h^2=144-64
h^2=80
h=(80)^(1/2), now we can find the area
A=8(80^(1/2))/2
A=4(80^(1/2)
A=35.78cm

Simplify the following equation. Explain each step and write the property used. 3x+2x-3+10=27
Answer:
x=4
Step-by-step explanation:
1. Add like terms: 5x+7=27
2. Use the subtraction property on both sides to get rid of 7: 5x=20
3. Divide 5 on both sides to get x by itself: x=4

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 :)

Three students took a math test.
• Liam completed the test in 2/4 hours
• Sarah completed the test in 1/2 of Liam's time
• Emma completed the test in 4/3 of Sarah's time
How long did it take for Sarah to complete the math test?
Answer:
20 minutes
Step-by-step explanation:
Liam completed the test in 1/2 of an hour. One half of that, Sarah's time, is 1/4.
Hence, you don't even have to solve for Emma's time, Sarah took twenty minutes to complete the test.

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,

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

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)

What is home?A home is a place where a person or a family lives, typically a house or an apartment.
It is a place of residence and refuge, where individuals or families can feel secure and comfortable.
We have,
There are several advantages of purchasing and owning a home, including:
Building equity: When you make mortgage payments, you are building equity in your home. This means that over time, you own more and more of your home and may be able to use the equity to your advantage.
Stability: Owning a home provides a stable living situation since you are not subject to rent increases or the possibility of eviction.
Investment: A home can be a good long-term investment as it generally appreciates in value over time. This means that if you sell your home in the future, you may be able to sell it for more than you paid for it.
Pride of ownership: Owning a home can give you a sense of pride and accomplishment, and you have the freedom to make changes and improvements to the property as you see fit.
Tax benefits: Homeowners may be able to deduct mortgage interest and property taxes on their income tax returns, which can result in significant savings.

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!
