Final answer:

Norah and Janice share £300 in a 9:1 ratio. Norah receives £270 while Janice gets £30, after dividing the total amount into 10 parts and then allocating the shares according to the ratio.

Explanation:

To calculate the share of the money Norah and Janice will each receive from £300 in the ratio of 9:1, we need to find out how many parts we divide the total sum into, and then allocate the appropriate amount to each based on the ratio.

Firstly, the total number of parts is 9 (for Norah) + 1 (for Janice) = 10 parts.

Next, we calculate the value of each part by dividing the total sum of £300 by 10: £300 / 10 = £30 per part.

Now, to find Norah’s share, we multiply 9 (her part of the ratio) by the value of one part: 9 * £30 = £270.

Janice’s share is simply one part, so it's £30: 1 * £30 = £30.

Therefore, Norah will receive £270 and Janice will receive £30.

The product of the dimensions of the box is 240.

What is mean by Cuboid?

A cuboid is the solid shape or three-dimensional shape. A convex polyhedron which is bounded by six rectangular faces with eight vertices and twelve edges is called cuboid.

Given that;

The dimensions of the cubes boxes are 4 by 5 by 6.

Now,

Since, The dimensions of a box that will hold twice as many cubes as a box.

And, The volume of the box = 4 x 5 x 6

                                            = 120

So, The volume of the  box that will hold twice as many cubes as a box;

= 2 x 120

= 240

And, We are not sure the exact dimensions of the box.

Thus, The product of the dimensions of the box is 240.

To solve the equation 0.5p = p + 5, subtract p from both sides and divide both sides by -0.5.

To solve the equation 0.5p = p + 5, we can start by simplifying both sides. Let's subtract p from both sides: 0.5p - p = 5. Combining like terms, we get -0.5p = 5. Now we can divide both sides by -0.5 to isolate p: p = 5 / -0.5. Dividing 5 by -0.5 gives us p = -10. Therefore, the solution to the equation is p = -10.

Repeated reasoning is a strategy used in mathematics to find multiplication facts by recognizing patterns and making generalizations. It involves using known facts to find other facts and making connections between different problems.

Repeated reasoning is a strategy used in mathematics to find multiplication facts. It involves recognizing patterns and using them to make generalizations about multiplication. When using repeated reasoning, you can start with a known fact, such as 2 x 3 = 6, and then apply that knowledge to find other facts. For example, you can use the fact that 2 x 3 = 6 to find 2 x 4 by adding another group of 2, resulting in 6 + 2 = 8.

Another example of using repeated reasoning is the commutative property of multiplication. This property states that the order of the factors does not change the product. So, if you know that 3 x 4 = 12, you can use repeated reasoning to determine that 4 x 3 = 12 as well.

By using repeated reasoning, you can build upon your knowledge of multiplication facts and make connections between different problems, which helps in understanding multiplication concepts more deeply.

To find out how many times your heart beats per minute, divide the total number of beats by the number of minutes. In this case, 240 beats in 4 minutes results in a heart rate of 60 beats per minute.

If your heart beats 240 times in 4 minutes, you can find out how many times it beats per minute by dividing the total beats by the total minutes. So, you would divide 240 beats by 4 minutes to calculate the heart rate in beats per minute (BPM).

The calculation would look like this:

240 beats \/ 4 minutes = 60 beats per minute.

Therefore, your heart beats 60 times each minute. It's interesting to note that the average heart rate is between 60 to 100 BPM for resting adults. If your heart beats 75 times per minute, it's considered within the average range.

Knowing your heart rate can be important for monitoring your fitness levels and overall health, especially during activities like exercising where your heart rate increases.

To solve for q in the equation '7m+n over q = 2m', multiply both sides by q and then divide both sides by 2m to isolate q.

To solve the equation 7m+n over q = 2m for q, we start by isolating q on one side of the equation. We can do this by multiplying both sides of the equation by q and then dividing both sides by 2m. This gives us the following steps:

Now, q is isolated, and the equation shows how q is related to m and n.
