If the digits A, B and C are added, the sum is the two-digit number AB as shown. What is the value of C?
A
B
+ C
______
AB
Answer:
C=9
Step-by-step explanation:
If A, B, and C are all single digits the mimimum sum for AB would be 10 as it is a two-digit number (or 11 if you do not consider 0 a digit)
AB-(A+B)=C
10-(1+0)=9 or 11-(1+1)=9
therefore C=9

If tom had 557 oranges and Billy had 676 more oranges than tom. How many oranges does Billy have.
Answer:
billy has 1233 oranges
Step-by-step explanation:
557+676=1233
you add 557 and 676 to figure out how much billy has
you can check your answer by subtracting 1233-557=676
Answer:
Billy has 1233 oranges.
Step-by-step explanation:
This is a simple, they have this many more than this person has, so an example is the B has 1 book, but Alex has a book collection of 10 books. They both have more than one book, but Alex has 10 books in total, with 9 more than B does.
So, for this question, Tom has 557, and Bill had 676 more than him, so that would mean you need to add 676 and 557 together to get 1233 oranges for just Billy. So that would be our answer.
please help, this is geometry
Answer:
Step-by-step explanation:
The formula is the same almost as the previous question you posted.
You want to find the major arc. That's almost the whole circle. If it was the whole circle, the formula would be 2 * pi * r
But we only want a part of it. Just how big is the angle we use in the formula?
A circle has 360 degrees to go around it. We've cut out a slice of it that is 30 degrees.
The remaining part is 360 - 30 = 330
Arc length = angle / 360 * 2 * pi * r
r = 3 m
Arc length = 330 / 360 * 2 * pi * 3
Arc length = 0.9167 * 6 * 3.14
Arc length = 17.27

Find the radius of the two other circles
Answer:
We draw the circles on a coordinate system. We know that a circle is has points that are equidistant from its centerpoint. So the point where these circles are tangent is the midpoint between the centerpoints.
We can use the midpoint formula.
M = ((x1 + x2) / 2 , (y1 + y2) / 2)
M = ((-2 + 6) / 2 , (3 + 9) / 2)
M = (2, 6)
These circles will have the same radii.
If we take the distance between the midpoint and (-2,3), we will have the radius of the circle with this centerpoint.
If we take the distance between the midpoint and (6,9), we will have the radius of the circle with this centerpoint.

you have piano lessons every 7 day and tuba lessons every 3 days today you have both lessons.
A. In how many days wil you have both lesson on the same day agian?
B. Not counting today or the day when you have the same lesson again, How many piano lesson will you have in between? Have many tuba lesson will you have in between?
Answer:
A.21 days
B.2, 6
Step-by-step explanation:
(a) In 21 days we will have both lessons on the same day again.
(b) Between each occurrence of having both lessons on the same day again, you will have 2 piano lessons and 6 tuba lessons.
a.
To find out when we will have both lessons on the same day again, we need to find the least common multiple (LCM) of 7 and 3.
The LCM of 7 and 3 is 21. This means that every 21 days, our piano and tuba lessons will align again.
b. Between each occurrence of having both lessons on the same day, you have 21 days. During these 21 days, you will have:
21 / 7 - 1 = 2 piano lessons.
21 / 3 - 1 = 6 tuba lessons.
So, between each occurrence of having both lessons on the same day again, we will have 2 piano lessons and 6 tuba lessons.

Answer:
see explanation
Step-by-step explanation:
Using the identity
sin²x + cos²x = 1
Consider left side
(2sinx + 3cosx)² + (3sinx - 2cosx)² ← expand parenthesis using FOIL
= 4sin²x + 12sinxcosx + 9cos²x + 9sin²x - 12sinxcosx + 4cos²x
Collect like terms

Step-by-step explanation:
We are told that ---> t = 0, x = 1.5, y = 6, and z = 23
1. y + 5
= 6 + 5
= 11
2. z - 2x
= 23 - 2(1.5)
= 23 - 3
= 20
3. 2z - 2y
= 2(23) - 2(6)
= 46 - 12
= 34
4. 2.6y - 2x
= 2.6(6) - 2(1.5)
= 15.6 - 3
= 12.6
5. 4(y - x)
= 4(6 - 1.5)
= 24 - 6
= 18
6. 4(2 + z) + 5
= 4(2 + 23) + 5
= 8 + 92 + 5

Please tell me how to solve this i just started geometry as a freshman and i don’t understand please!!!
Answer:
80 degrees
Step-by-step explanation:
The whole angle EBD is 115 degrees, and angle DBG is 35 degrees, therefore
angle GBE is 115-35=80 degrees
Think about it like this, DBG and GBE need to add up to the angle measure of EBD, in other words 35 + GBE = 115
Answer:
Step-by-step explanation:
<DBE = <DBG + <GBE
<DBE = 115 Given
<DBG = 35 Given
<GBE = ?
You have to know a couple of things before you start.
All the angles meet at B. Notice B is the center letter. the top given is the equation you need to solve the question.115 = <GBE + 35 Subtract 35 from both sides.
115 - 35 = <GBE
80 = <GBE
Is it possible for a metallic element to have a melting point of -38.87 degree celcius? explain.
Answer:
this is not possible
No, it is not possible for a metallic element to have a melting point of -38.87 degrees Celsius under standard conditions.
The melting point of a metallic element is typically a positive value, indicating the temperature at which the solid form of the element transitions into a liquid state.
A negative melting point would be a highly unusual and physically contradictory concept because it would imply that the element exists in a liquid state at temperatures below absolute zero, which is the lowest possible temperature in the Kelvin scale (-273.15 degrees Celsius). At temperatures below absolute zero, the thermal motion of particles comes to a minimum, and it's not possible for a substance to exist in a liquid state.
In reality, metallic elements have melting points that are well above absolute zero, typically ranging from hundreds of degrees Celsius to thousands of degrees Celsius, depending on the specific element. Melting points for metals are typically positive values due to the nature of metallic bonding and the need for sufficient thermal energy to overcome the forces holding the metal atoms together in a solid lattice structure.

Sylvie is mixing concrete for her patio. For every 26.7 pounds of concrete mix, she needs to add 1 quart of water. Sylvie buys 80 kilograms of
concrete mix
1 kilogram 2.2 pounds
How many quarts of water, rounded to the nearest tenth, does Sylvie need to add to 80 kilograms of concrete mix?
Step-by-step explanation:
that back and forth between the different scales is the only task challenge. you need to focus to not mix things up.
so if I understand correctly, we should use the conversion rate of 1 kg = 2.2 pounds.
she should add 1 quart of water to every 26.7 pounds of concrete mix.
80 kg = 80×2.2 pounds = 176 pounds.
we need as many quarts of water as there are units of 26.7 pounds in 176 pounds.
176/26.7 = 6.5917603... quarts of water needed.
that would be rounded 6.6 quarts of water.
