Answer:
385 cards
Step-by-step explanation:
First, find 40% and 25% of 1100.
2/5 * 1100
2200/5 = 440 cards dated before 1970
1/4 * 1100
1100/4 = 275 cards dated between 1970 and 2000
Then add the two amounts together.
440 + 275 = 715 cards between pre-1970 and 2000
After that, subtract your new sum from 1100.
1100 - 715 = 385 cards after 2000
(Or to make it easier, just find 35% of 1100.)

Answer:
The correct option is A
Step-by-step explanation:
Since (1, 3) are the solutions to the function g(x), then
g(x) = (x – 1)(x – 3) = x² –3x – x + 3 = x² – 4x + 3
We know that f(x) is on the same plane and f(1) = 1.
Let's take g(1) = (1 – 1)(1 – 3) = 0
Therefore, when x = 1; f = 1 and g = 0. Hence
g(1) = f(1) – 1
In order words, g(x) could be f(x) – 1.
The correct option is A
You and your friend join a new gym that requires a one-time joining fee and monthly payments. Your friend chooses the 1 year plan and pays $687, while you elect the 18 month contract which costs $981. Use this information to determine the linear model used to calculate cost from months of membership.
Answer:
C = 99 + 49m
x = $99
y = $49
Step-by-step explanation:
Let
x = one time joining fee
y = monthly payment
Your friend:
1 year = 12 months
x + 12y = $687
You:
x + 18y = $981
x + 12y = 687 (1)
x + 18y = 981 (2)
Subtract (1) from (2)
18y - 12y = 981 - 687
6y = 294
Divide both sides by 6
y = 294 /6
= 49
x = $49
Substitute y = 49 into
x + 12y = 687
x + 12(49) = 687
x + 588 = 687
x = 687 - 588
= 99
x = $99
C = 99 + 49m
Where,
C = total charges
m = number of months
99 = a one time joining fee
49 = charges per month

Step-by-step explanation:
Max has a drawer full of green and red socks. He has three times times as many red socks subtracted from four times as many green socks which he believes is 50 socks. Half the number of green socks plus one-third of the number of red socks is 36. How many of each colour does he have?
Answer:
There are 42 red colour socks and 44 green color socks
Step-by-step explanation:
Let there are r red socks and g green socks.
ATQ,
He has three times times as many red socks subtracted from four times as many green socks which he believes is 50 socks.
4g-3r=50 ....(1)
Half the number of green socks plus one-third of the number of red socks is 36.
[tex]\dfrac{g}{2}+\dfrac{r}{3}=36\\\\3g+2r=216\ .....(2)[/tex]
Multiply equation (1) by 2 and equation (2) by 3.
8g-6r = 100 ....(3)
9g +6r = 648 ....(4)
Add equation (3) and (4)
8g-6r + 9g +6r = 100+648
17g = 748
g = 44
Put the value of g in equation (1).
4(44)-3r=50
176-3r = 50
176-50 = 3r
r = 42
Hence, there are 42 red colour socks and 44 green color socks.

A scientist observed a bacterium in a microscope. It measured about 0.0000029 meter in diameter. Which of the following is closest to 0.0000029?
A.
2×10−6
B.
2×10−5
C.
3×10−5
D.
3×10−6
Answer: A. [tex]2\times10^{-6}[/tex].
Step-by-step explanation:
Given: The diameter of bacterium = 0.0000029 meter
≈ 0.000002 meter [ with 6 decimal places]
[tex]=\dfrac{2}{1000000}=\dfrac{2}{10^6}[/tex]
[tex]=2\times10^{-6}[/tex] meters [[tex]\dfrac{1}{a^n}=a^{-n}[/tex]]
i.e. [tex]2\times10^{-6}[/tex] closest to 0.0000029.
Hence, the correct option is A. [tex]2\times10^{-6}[/tex].

As an estimation we are told £3 is €4. Convert €40 to pounds
Answer:
£30
Step-by-step explanation:
The ratio is 3:4. x:40=3:4 multiplied by 10, 30:40.
There are 30 pounds in 40 euros, therefore, €40 = £30.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, £3 is €4, therefore,
€4 = £3
€1 = £(3/4)
€40 = £(3/4)×40
€40 = £30
Hence, 40 euros is equal to 30 pounds, €40 = £30.

solve for x
|2x-4|+6=8
Solve for x
|2x -4| + 6 =8
subtract 6 from both sides, then solve
|2x - 4| = 2 and |2x -4| = -2
2x - 4 = 2 2x - 4 = -2
+4 +4 +4 +4
2x = 6 2x = 2
divide by 2 to isolate the variable
