Answer:
14 bows
Step-by-step explanation:
Isabella has 7 yards of ribbon to make bows. Each bow is made from a peace of ribbon that is 1/2 yard long. How many bows can Isabella make?
The above question is calculated as:
1/2 yard of ribbon = 1 bow
7 yards of ribbon = x bows
We cross multiply
1/2 yard of ribbon × x bows = 7 yards of ribbon × 1 box
x bows = 7 yards of ribbon × 1 box/1/2 yard of ribbon
x bows = (7 ÷ 1/2 ) bows
x bows = 7 × 2 bows
= 14 bows
Therefore, Isabella can make 14 bows

The image of the point (-6, -2) after dilation by a scalefactor of 4 centered at the origin is (-24, -8).
What is a scale factor?
A scalefactor is defined as the ratio between the scale of a given original object and a new object,
We have,
To find the image of the point (-6, -2) after dilation by a scale factor of 4 centered at the origin, we can use the following formula:
(x', y') = (kx, ky)
where (x, y) are the coordinates of the original point, (x', y') are the coordinates of the image after dilation, k is the scale factor, and (0, 0) is the center of dilation.
Substituting the values given in the problem, we get:
(x', y') = (4*(-6), 4*(-2))
Simplifying,
(x', y') = (-24, -8)
Therefore,
The image of the point (-6, -2) after dilation by a scalefactor of 4 centered at the origin is (-24, -8).

Final answer:
The number that when divided by 12 equals 72 is 864. This is found by multiplying the divisor (12) with the desired quotient (72). Therefore, the answer is 864.
Explanation:
To solve for the number that when divided by 12 gives an answer of 72, we need to leverage the standard division operation in mathematics.
To find this number, we simply multiply 12 (the divisor) by 72 (the quotient). This is the reverse of the division process, also known as multiplication.
When we perform this calculation, 12 multiplied by 72, we find the answer to be 864. Therefore, 864 is the number that when divided by 12 gives you 72.
