Answer:

25% or 30L

Step-by-step explanation:

100% is 120L, we know 75% is acid, we need the other 25% to make the 100%. 25% of 120 is 30, so 30 liters is pure acid

Answer:

117 sorry if I'm wrong ooh this agg

Answer:

95°

Step-by-step explanation:

m∡A = m∡C

there are 360 degrees in a kite

let 'x' = # degrees in angle A and in angle C

x + 127 + x + 43 = 360

2x + 170 = 360

2x = 190

x = 95°

Answer:

2) y=-2x+3

3) y=[tex]\frac{1}{2}[/tex]x+2

4) y=2x-5

5) y=[tex]\frac{2}{3}[/tex]x+2

6) y=-3x+5

7) y= [tex]\frac{2}{3}[/tex]x-1

Answer:

A) c = 5 ft

Step-by-step explanation:

a = 3

b = 4

3^2+4^2 = c^2

c^2 = 9+26 = 25

c = 5

Answer:

B

Step-by-step explanation:

Unfortunately, I dont really have a explanation for this besides yellow square is larger than both red and green, so using judging by the answers, it has to be B.

Answer:

C I think

Step-by-step explanation:

Answer:

A, f(x) ≥ -36

Step-by-step explanation:

The range is all the possible y values, also called f(x) values.

In this case, the range of the graph extends from -36 to infinity, so the correct answer is f(x) ≥ -36.

Let me know if this helps!

Answer:

5 dimes and 2 quarters

Step-by-step explanation:

A dime is worth 10 cents. To figure out how many dimes it takes to get to fifty, do:

[tex]50/10[/tex]

Doing this will give you the answer of 5 dimes.

A quarter is worth 25 cents. To figure out how many dimes it takes to get to fifty, do:

[tex]50/25[/tex]

Doing this will give you the answer of 2 quarters.

Answer:

1. 5 Dimes

2. 2 Quarters

Step-by-step explanation:

A fifty-cent coin can be written as $0.50. A dime can be written as $0.10. Now you just solve with the simplest math by figuring out how many 0.10's you need to get 0.50. This would be 5

Now a quarter can be written as $0.25. Now you just do the same thing as before. So you would need two $0.25 to get $0.50

Step-by-step explanation:

Answer:

337285

Step-by-step explanation:

Answer:For these, n is equal to the term you want. So you substitute the number in for whichever term you want. This means:

a) 1 (1st term) + 5 = 6

2 (2nd term) + 5 = 7

3 (3rd term) + 5 = 8

4 (4th term) + 5 = 9

10 (10th term) + 5 = 15

And so on for b (not going to keep writing the term, I’m sure you get that by now.

b) 2(1) - 1 = (2x1) - 1 = 1

2(2) - 1 = (2x2) - 1 = 3

2(3) - 1 = (2x3) - 1 = 5

2(4) - 1 = (2x4) - 1 = 7

2(10) - 1 = (2x10) - 1 = 19

Hope this helps :)

Answer:

1.20 times 11. I hope it helped!

Answer:

2

Step-by-step explanation:

you can't add 4x and 5

so you use the distributive property

multiply 2x and 4x to get 8x and 2x and 5 to get 10x

then your answer should be 2

Answer:

Step-by-step explanation:

To be perpendicular m1(m2)=-1

-1m/7=-1

m=7

So the perpendicular line will have 7 as the linear coefficient

y=7x+b

Answer:

a = 3/28

Step-by-step explanation:

To start solving for a variable, you need to isolate it.

-4/3b = 4a

-4/3 divided by 4 equals -4/12 or -1/3

a = -1/3b

To completely solve for a we need to plug it back in and solve for b.

b = (4(-1/3b)) - 3/4

b = -4/3b - 3/4

7/3b = -3/4

b = -9/28

Finally, we can plug b back in to the previous equation we got for a to solve for a.

a = -1/3(-9/28)

a = 3/28

Furthermore, we can check if this is correct by plugging in 3/28 for a into the original problem and see if we get what we got for b (-9/28)

Reflection of point (5, -3) across line y = x is symmetrical point:

Correct choice is C

See attached

This is 90° counterclockwise or 270° clockwise rotation

Correct choice is D

Answer: Yes, your friend is correct

Additional Note: Associative Property is modifying the addendum grouping does not alter the number.

Answer: The friend is wrong.

Step-by-step explanation:

In this equation, they are doing the commutative property. Commutative property is a property that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The Associative Property of Addition is a property which means that rearranging the parentheses in an expression will not change the result. Clearly, they didn’t do that; they just switched the 7 and x around which is the commutative property.

This might be slightly confusing but I hope this helps :’)

Answer:

P(X = 0) = 0.12.

P(X = 1) = 0.37.

P(X = 2) = 0.43.

P(X = 3) = 0.08

Step-by-step explanation:

12% have no children

This means that P(X = 0) = 0.12.

37% have one child

This means that P(X = 1) = 0.37.

43% have two children

This means that P(X = 2) = 0.43.

8% have three children.

This means that P(X = 3) = 0.08

Answer:

The amount of money in the account after t years is given by: [tex]A(t) = 5000(1.015)^{4t}[/tex]

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Invested $5000 at 6% per year and is compounded quarterly​

This means, respectively, that [tex]P = 5000, r = 0.06, n = 4[/tex]

So, the amount of money in the account after t years will be given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(t) = 5000(1 + \frac{0.06}{4})^{4t}[/tex]

[tex]A(t) = 5000(1.015)^{4t}[/tex]
