There are 6 shirts in the batch

Step-by-step explanation:

The given is:

1. Screen printing a batch of shirts takes 0.4 minutes to make a shirt

2. The initial set time is 4 minutes

3. It takes 6.4 minutes to screen-print a batch of shirts

We need to find how many shirts are in the batch

Let us represent these information in a function

Assume that there are n shirts in the batch

Then t(n) is the total time to screen-print n shirts in the batch

∵ There is initial set time = 4 minutes

∵ It takes 0.4 minutes to make a shirt

∵ The number of shirts  = n

∴ t(n) = 0.4 n + 4

∵ It takes 6.4 minutes to screen-print a batch of shirts

∴ t(n) = 6.4

∵ t(n) = 0.4 n + 4

∴ 6.4 = 0.4 n + 4

- Subtract 4 from both sides

∴ 2.4 = 0.4 n

- Divide both sides by 0.4

∴ n = 6

There are 6 shirts in the batch

L || m
Alona [7]

Answer:

c. m∠1 + m∠6 = m∠4 + m∠6

Step-by-step explanation:

Given: The lines l and m are parallel lines.

The parallel lines cut two transverse lines. Here we can use the properties of transverse and find the incorrect statements.

a.  m∠1 + m∠2 = m∠3 + m∠4

Here m∠1 and m∠2 are supplementary angles add upto 180 degrees.

m∠3 and  m∠4 are supplementary angles add upto 180 degrees.

Therefore, the statement is true.

b. m∠1 + m∠5 = m∠3 + m∠4

m∠1 + m∠5 = 180 same side of the adjacent angles.

m∠3 + m∠4 = 180, supplementary angles add upto 180 degrees.

Therefore, the statement is true.

Now let's check c.

m∠1 + m∠6 = m∠4 + m∠6

We can cancel out m∠6, we get

m∠1 = m∠4 which  is not true

Now let's check d.

m∠3 + m∠4 = m∠7 + m∠4

We can cancel out m∠4, we get

m∠3 = m∠7, alternative interior angles are equal.

It is true.

Therefore, answer is c. m∠1 + m∠6 = m∠4 + m∠6

An image formed by a circular spotlight has a radius of 124 centimeters. What is the area of the circular image? Use 3.14 for pi
Lemur [1.5K]

area = pi X radius squared

 so area = 3.14 x 124^2

= 3.14 x 15376 = 48,280.64 square centimeters.

Which example below uses deductive reasoning?
rusak2 [61]
Deductive reasoning is one that necessarily follows, not one that likely follows (this would be an inductive reasoning).

Here the important information is that all squares are also parallellograms, which means that they also necesarily have all the properties of the parallelogram - the correct answer is D.
