Please help me asap. I need an answer and full explanation. 1st person to complete that gets Brainliest. Question: Amelia likes to collect pokemon cards. She currently has 34 water cards and 29 fire cards. How many more fire cards does she need to collect so her ratio of the number of water cards to fire cards is 2:3?
Thanks and stay perfect.
Answer:
22 cards
Step-by-step explanation:
Set up a ratio.
[tex]\frac{34}{29+x} =\frac{2}{3}[/tex]
[tex]58+2x=102[/tex]
[tex]2x=44[/tex]
[tex]x=22[/tex]
Check: Add 22 to 39. 22+29=51
34/51 = 2/3

Angel is saving all of his money for a ticket to Grad Bash. Before he started working, he had $7.50 in his bank account On Saturday, he works 5 hours and earns $42.50 On Sunday, he works 8 hours and earns $68,00
Which of the following functions models Angels savings?
Answer:
The second choice is correct. (f(x) = 8.50x+7.50)
Angel had +7.50 dollars to start off with and then worked 5 hours to get 42.50 dollars. This means, she earns 8 dollars 50 cents per hour, meaning that 8.50x would represent the total amount of money that she would earn from her job.

y=−4x−3
y=−2x+1
x=x=x, equals
y=y=y, equals
Answer:
x = -2, y = 5.
Step-by-step explanation:
y=−4x−3
y=−2x+1
Because y is common to both left sides:
-4x - 3 = -2x + 1
-4x + 2x = 1 + 3
-2x = 4
x = 4/-2
x = -2.
So y = -4(-2) - 3
= 8 - 3
= 5 .

Answer:
The distance between point R and point Z is 7 blocks below.
Step-by-step explanation:
The question says the distance between Point r and Point Z. R to Z is going down. You start at R and find Z. When you have done that, You count the number of blocks or spaces that they have in between the space. And when you have counted you get your answer. The answer is never a negative number always positve even if the point is has a negative number with posivte or a negivate with negative or a postive wwith a postive.

Use Pythagorean Theorem to solve for x.
HELP ME PLZZZZ!!!! ASAP
Answer: [tex]2\sqrt{22}[/tex]
Step-by-step explanation:
Pythagorean theorem: [tex]a^{2} +b^{2} = c^{2}[/tex], where a and b are the legs and c is the hypotenuse.
We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.
[tex]9^{2} +b^{2} = 13^{2}[/tex]
[tex]81 +b^{2} = 169[/tex]
Since we don't know what [tex]b^{2}[/tex] is, we're going to isolate it by subtracting 81 on both sides
[tex]b^{2} = 88[/tex]
We have to square root both sides in order to find out b (or x in the problem).
[tex]\sqrt{b^{2}} = \sqrt{88}[/tex]
When you put this on a calculator it would result in [tex]2\sqrt{22}[/tex] which is the answer d in the problem.

Answer:
The 2nd option:
1.339×10⁶
Step-by-step explanation:
To find the combined capacity, add the two values together so:
(8.12×10⁵ ) + ( 5.27 × 10⁵ )
It will be simpler to add if you change it out of its
standard form
812000+527000
= 1339000
Now you can write in back in standard form, which will be
1.339×10⁶

The first two terms of a sequence are a1 =4 and a2= -2. Let a3 be the third term when the sequence is arithmetic and let b3 be the third term when the sequence is geometric. Find a3+b3
Answer:
a3 + b3 = -7
Step-by-step explanation:
When the sequence is A.P
a1 =4 and a2= -2
Common difference,d = a2 - a1
= -2 - 4
d = -6
a3 = third term
a3 = a1 + 2d
= 4 + 2(-6)
= 4 - 12
= -8
a3 = -8
When the sequence is geometric
a1 =4 and a2= -2
Common ratio, r = a2/a1
= -2/4
r = -1/2
Or
r = -0.5
b3 = third term
b3 = ar²
= 4 * (-1/2)²
= 4 * 1/4
= 4/4
= 1
b3 = 1
a3 + b3 = -8 + 1
= -7
a3 + b3 = -7
