What is the value of v if 13v = 65

NemiM [27]

Answer:

$v=5$

Explanation:

The equation is asking for multiplication (13 * v), and the opposite of multiplication is division. So if we divide 65 by 13, we find 5.

13 * 5 = 65

Zoe's mom is making super hero capes for the guests at her little brother's birthday party. Each cape uses of a yard of fabric.

kumpel [21]

Answer:

Part A: 10 complete capes.

Part B: 120 minutes.

Step-by-step explanation:

Part A:

Given:

Amount of fabric required for 1 cape is 1 yard.

Total amount of fabric bought by Zoe's mom are 10 yards.

Using unitary method,

∵Number of capes made from 1 yard fabric = 1

∴ Number of capes made from 10 yard fabric = $10\times 1=10$

Part B:

Given:

Time taken to make 1 cape is 12 minutes.

Using unitary method,

∵Time taken to make 1 cape = 12 minutes.

∴ Time taken to make 10 capes = $12\times 10=120$ minutes.

Write an equation from the information given: A rectangle is twice as long as it is wide. The perimeter of the rectangle is 18.

Agata [3.3K]

Let width = x, Therefore the length must equal 2x

Therefore insert these values on the sides of a rectangle.

Add: 2x + 2x + x + x = 18

Therefore 6x = 18

x = 3

What is the answer to this? i can’t figure it out.

Svetach [21]

Answer:

25 +0i

Step-by-step explanation:

The conjugate of a complex number is that number with the sign of the imaginary part reversed.

For z = -3+4i, its conjugate z* is -3-4i. The product of z and z* is ...

(-3 +4i)(-3 -4i) = -3(-3 -4i) +4i(-3 -4i)

= 9 +12i -12i -16i² = 9 +16 = 25

The real part of the product is 25; the imaginary part is 0.

(-3 +4i)(-3 -4i) = 25 +0i

_____

You may have noticed that (z)(z*) = |z|², the sum of the squares of the real and imaginary parts. It is always a non-negative real number.
