Jada had some dimes and quarters that had a total value of $12.50. The relationship between the number of dimes, d, and the number of quarters, q, can be expressed by the equation
01.d + 0.25q = 12.5.
1. If Jada has 4 quarters, how many dimes does she have?
2. If Jada has 10 quarters, how many dimes does she have?
3. Is the number of dimes a function of the number of quarters? If yes, write a rule (that starts with d =...) that you can use to determine the output, d, from a given input, q. If no, explain why not.

Answers

Hi! This might be long but I hope it helps!

1. 115. If q=4, then the equation tells us that 0.1d+(0.25)⋅4=12.5. Subtracting 1 from both sides gives 0.1d=11.5, so d=115.

2. 100. If q=10, then the equation tells us that 0.1d+(0.25)⋅10=12.5. Subtracting 2.5 from both sides gives 0.1d=10, so d=100.

3. Yes. If you know the number of quarters, then you can determine the number of dimes from the equation. We can even write the equation in a way that shows this: d=125−2.5q. The expression 125−2.5qrepresents the output—it is the rule that determines the output d from a given input q.

Answer:

1. 115. If q=4, then the equation tells us that 0.1d+(0.25)⋅4=12.5. Subtracting 1 from both sides gives 0.1d=11.5, so d=115.

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

Step-by-step explanation:

This is a linear equation, and we will need to get the variable by itself.

Let's calculate!

[tex]8+3x=14\\3x=14-8\\3x=6[/tex]

Now we divide both sides by 3. Dividing 3 by 3 is just 1, and we don't need to write the 1, and 6 divided by 3 is two! So your equation will look like this:

What are the coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right?

Answers

(-9,1) should be the answer not completely sure tho

The coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right are (8,9) (for clockwise rotation) and (0,-9) (for counterclockwise rotation)

How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?

Let the point be having coordinates (x,y).

Case 1: If the point is in first quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 2: If the point is in second quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 3: If the point is in third quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 4: If the point is in fourth quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Case 5: For points on axes

You can take that point in any of the two surrounding quadrants. Example, if the point is on positive x axis, then it can taken as of first quadrant or fourth quadrant.

Case 6: On origin

No effect as we assumed rotation is being with respect to origin.

For this case, the point (-9,4) (present in second quadrant) is rotated by 90 degrees.

This rotation can be either clockwise, or counterclockwise.

Thus, for each case, we have:

case 1: Clockwise rotation:

Then (x,y) → (y, -x), therefore, (-9,4) → (4, 9)

case 2: Counterclockwise rotation:

Then (x,y) → (-y, x), therefore, (-9,4) → (-4, -9)

Now, when shifting to right by 4, that means, we're making no changes vertically, but old x-coordinates are increased by 4 to make them shift to right side as value of x increases as we go more and more to the right side with respect to the origin and in defaultly oriented cartesian space.

Thus, we have:

case 1: Clockwise rotation:

After translation of 4 units right:

(4, 9) → (4+4, 9) = (8,9)

case 2: Counterclockwise rotation:

After translation of 4 units right:

(-4, -9) → (-4+4, -9) = (0,-9)

Thus, the coordinates of the point (-9, 4) after a 90 degree rotation followed by a translation 3 units right are (8,9) (for clockwise rotation) and (0,-9) (for counterclockwise rotation)

Answers

Answer:

The terms equivalent to - 6 are

- 10 - ( - 4)

26 - 32

Answer:

Only the 2nd and 3rd expressions are equal to -6

Step-by-step explanation:

The only way to do this is evaluating ot actually doing each expression:

Some key skills needed are subtraction with negative numbers, distributing the negative properly, and addition.

The first one is -7+13. This can be rewritten as 13-7. And this is 6, so it is not equal to -6. The 2nd one is -10-(-4). You have to distribute that minus sign after the -10 to the -4. Think of the subtraction symbol I mentioned as -1. -1(-4) is 4 since the negative signs cancel out. It would then be -10 + 4 which -6. So this works. This one is 26 - 32. You have to subtraction here. 26 - 32 is the opposite of 32 - 26. 32 - 26 is 6, so 26 - 32 would be -6. So the 3rd one is another one eqial to -6. This is simple subtraction. 16 - 10 is 6, so this one definitely does not work. This uses the same skill as number 2. Think of the minus sign after the positive 3 as a -1. -1(-3) is 3, so it would be 3 + 3 which is 6.

Only the 2nd and 3rd ones work. Hope you understood and have a nice day!!

the speed of light is approximately 3 x 10 to the 8th power meters per second, while the speed of sound is approximately 3.4 meters per second. How many times faster is the speed of light than the speed of sound?

Answers

Answer:

The speed of light is 8.8x10⁵ times faster than the speed of sound.

Step-by-step explanation:

We can find how many times faster (R) is the speed of light than the speed of sound as follows:

[tex] R = \frac{c}{v_{s}} [/tex]

Where:

c: is the speed of light = 3x10⁸ m/s

[tex]v_{s}[/tex]: is the speed of sound = 340 m/s (the value given in the statement, 3.4 m/s, is wrong)

[tex]R = \frac{3 \cdot 10^{8} m/s}{340 m/s} = 8.8 \cdot 10^{5}[/tex]

Hence, the speed of light is 8.8x10⁵ times faster than the speed of sound.
