Answer:
She has wrapped 15 packages.
Step-by-step explanation:
Heres how I did it. I used my fingers for this, it's a little odd I know but it works. I put up one finger for each half. So each finger represents one half. I needed to get to 2 1/2 so I put up two finger and I said "that's one " because a half plus a half is a whole or just one. Then I put up one more finger and I said " That's one and a half". I then put up two more and then I had 2 1/5. What I did then was count how many fingers I had up. I had 5 fingers up. So then I multiplied 3 x 5 and that gave me 15. Hope I could help!
What is f(-2) if f(x) =1/2x?
help meee pleasee !!!
Answer:
It would be relation B and f (x)
Step-by-step explanation:
for it to be a function X (-8) can only have one outcome, however that isn't the case with A.
and I believe if I'm remembering correctly, one-to-one correspondence is each element of one set is only paired with one element of the other set which isn't true for B, so it should be f (x), though you may want to look it up for yourself to make sure.
2[tex]^{2}[/tex] + 5 + 50 ÷ 2(5)
Hey there!
2^2 + 5 + 50 ÷ 2(5)
2^2 = 2 • 2 = 4
4 + 5 + 50 ÷ 2(5)
4 + 5 = 9
9 + 50 ÷ 2(5)
50 ÷ 2 = 25
9 + 25(5)
25(5) = 125
9 + 125
= 134
Answer: 134 ☑️
Good luck on your assignment and enjoy your day!

Students in a science class investigated how the speed of sound changes with the air temperature outside. The data are shown in the scatterplot.
Based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 45°C?
350 m/s
355 m/s
360 m/s
365 m/s
Answer:360 m/s
Step-by-step explanation:
The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
As we can see in the graph:
When the air temperature is 10°C the speed of sound is around 337m/s
When the air temperature is 20°C the speed of sound is around 344m/s
When the air temperature is 30°C the speed of sound is around 348m/s
When the air temperature is 40°C the speed of sound is around 355m/s
From the above observation, the air temperature increases the speed of the sound increases.
So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.
Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.

3a+3b+2b=3a+5b
solve for a: a=-5b/3
solve for b: b=-3a/5
Answer:
3a+5b
Step-by-step explanation:
3(a+b+)2b
the first thing you'd do would be distribute 3 to a and b
3a+3b+2b
you then would combine like terms which are 3b and 2b

Justin and his friend Dan went to the movies. If they each bought popcorn for $4.25 and a soda for $2.25, what was their total bill after adding 5 ¼ % sales tax?
Answer:$6.84
Step-by-step explanation:
$4.25 + $2.25 = $6.50
5 1/4% in decimal form is 5.25%
6.50 multiplied by 5.25% = $0.34
$6.50 + $0.34 = $6.84

What is wrong with this equation 7/9-8/9=1/9
Answer:
the answer would be -1/9
because you're subtracting 8/9 from 7/9, not the other way around.
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
7/9-8/9=1/9
We have a common denominator
( 7-8) 1
--------- = ----
9 9
7 -8 is equal to -1 not 1
The answer should be -1/9 not 1/9

A salesperson’s commission rate is 4%. What is the commission from the sale of $39,000 worth of furnaces? Suppose sales would double. What would be true about the commission?
Answer:
The earnings will double
Step-by-step explanation:
Step one:
given data
we are told that the sales person's earnings is 4% of the sales made.
given that the sales made is $37,000 worth of furnaces.
Step two:
we want to find 4% of $37,000
=4/100*37000
=0.04*37000
=1480
hence for $37,000 the earning will be $1480.
Now suppose sales is doubled that is 37000*2= 74000
we want to find 4% of $74,000
=4/100*74000
=0.04*74000
=2960.
the earnings is $2960.
So if sales doubles the earnings will double

Answer:
[tex]-64y^{2}[/tex]
Step-by-step explanation:
You first multiply (-4)^3, then add the exponents of y, which is [tex]y^{2}[/tex].
Answer:
-4^3*y^2
Step-by-step explanation:
Because there are 3 “-4”s being multiplied it would be to the power of 3.
Because there are 2 ”y”s being multiplied it would be to the power of 2
Then you just need to multiply them together.
