7.C.J. says the quotient of -3/4 divided by 1/4 is - 1/3

Elanso [62]

The correct quotient is -3

The mistake CJ likely made is multiplying using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4

From the question,

We are to determine the correct quotient.

The given division operation to be carried out is -3/4 divided by 1/4

The correct quotient can be determined as shown below

$-\frac{3}{4} \div \frac{1}{4}$

Multiply $-\frac{3}{4}$ by the reciprocal of $\frac{1}{4}$

The reciprocal of $\frac{1}{4}$ is $\frac{4}{1}$

Then, we get

$-\frac{3}{4} \times \frac{4}{1}$

This gives

$-\frac{12}{4}$

= -3

The correct quotient is -3

The mistake CJ likely made is multiplying using the reciprocal of -3/4.

Hence, the correct quotient is -3

The mistake CJ likely made is He multiplied using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4

The diameter of a bicycle wheel is 20 inches. Which measurement is closest to the circumference of the wheel

algol [13]

Answer:

62.8 inches

Step-by-step explanation:

✓We can determine the

Circumference of the wheel of the bicycle using the expression below;

Circumference= (πd) ...........eqn(1)

Where d= diameter = 20inches

If we substitute the value of " diameter" into eqn(1)

Circumference = (π × 20)

= 62.8inches

(Where π= 3.142)

Therefore, measurement that is closest to the circumference of the wheel is 62.8inches

Which of the following parabolas opens down?

Veseljchak [2.6K]

ANSWER

The correct answer is C.

EXPLANATION

The directrix of the parabolas are parallel to the x-axis.
This means that, the orientation of the parabola is parallel to the y-axis.
We compare the focus and the directrix to determine whether the parabola opens downwards or upwards.
If the directrix is above the focus, then the parabola opens downwards.
On the other hand if the directrix is below the focus , then the parabola must open upwards.
If you look at option C, y=-2 isthe directrix. The focus is (3,-5). Since the the y-value of the focus , -5 is less than y=-2 which is the directrix, this parabola must open down.

The correct answer is C.
