Step-by-step explanation:

Answer:

Step-by-step explanation:

There are two ways to do this. You could use your calculator to find out the decimal numbers that are equivalent to the two given fractions. Then check which one of the givens falls between these two numbers. I wouldn't do it that way -- not when you are told that the answer has 56 as the denominator.  So ...

The best way to do it is to change the two givens so that they have a denominator of 56

3/7 = 3*8/7*8 = 24 / 56

7*7 / 7*8 = 49 / 46

So you need a number that is between 49 and 24

There is only one 27 / 56

Answer:

y = 1/3a

Step-by-step explanation:

y = ka

1 = 3k

k = 1/3

Confirm constant: (4-1)/(12-3) = 3/9 = 1/3

1 = 3(1/3) + b

1 = 1 + b

b = 0

y = 1/3x or 1/3a

Answer:

x > -7

make sure to put the sign with the line under it because I can't type it

Answer:

[tex]7x + 49 \degree = 2x + 94\degree \\ 7x - 2x = 94\degree - 49 \degree \\ 5x = 45\degree \\ x = \frac{45}{5} \\ x = 9 \\ check \\ 7(9) + 49 = 112\degree \\ 2(9) + 94 = 112\degree[/tex]

Answer:

$0.57 for each can of cat food

Step-by-step explanation:

2.85/5 = 0.57 giving you the answer

Answer:

it would cost 0.57 cents!

Explanation:

you'd have to divide 2.85 by 5, because if it is that much for 5 cans, and he only wants to buy 1, you'd divide it by 5, to get 0.57 :)

Answer:

$525

2.9 years

Step-by-step explanation:

This question is about financial management. It is to be noted that it would take around 2.9  years for her balance to increase from $300 to $450.

Note that according to the question,

After 4 years, Emma would owe about $525 for her original purchase of $300.

The equation will be:

300 * (1 + x)[tex]^{4}[/tex] = 525 (This is based on the compound interest formula_

⇒ (1+x)[tex]^{4}[/tex] = 7/4 (If we divide both sides by 300)

Hence

x = 0.1502

= 15.02%

When the balance ups from $300 to $450,

We can state that:

300 * ( 1+ 15.02%) [tex]^{y}[/tex] = 450

⇒ Hence, y = 2.9 years.

Answer:

fun fact : by reading what i just right u just lost 5 sec of your life

Step-by-step explanation:

Answer:

for this problem we use the sine function

[tex] \sin(x) = \frac{opp}{hyp} \\ \sin(38 ) = \frac{x}{100} [/tex]

multiply both sides of the equation by 100

[tex]100 \sin(38) = \frac{100x}{100} [/tex]

100 cancels on the right hand side of the equation

[tex]100 \sin(38) = x \\ x = 61.566\:ft[/tex]

Answer: 5 pens cost Rs.50

Explanation: Since 1 pen costs Rs.10, you will need to multiply the number of pens (1) and the cost of that number of pens (Rs.10) by the amount of pens you must find the cost for (5). Since 10 times 5 is 50, that means that 50 is the cost of 5 pens.

y=1/2x-5

Step-by-step explanation:

By solving for slope, we get 1/2

We use the equation b=y-mx to find the y intercept

b= -5

Equation: y= 1/2x - 5

Answer:

Step-by-step explanation:

Rotate 180 degrees about the origin

X(x,y) ====> X'(-x,-y)

K(-5 , - 9) = K ' (- -5, - - 9)

K' (5,9)

3 Units Left.

y is unchanged.

x becomes x - 3

K'(5,9) ===>k" (5 - 3,9)

k"(2,9)

The leftward motion does not look done the same way as moving a parabola left. But you are just changing the x value to move a point left. You are not imposing other rules on the figure.
