Answer:

Number 4 (54,811 x two fourths)

Step-by-step explanation:

54,811 x 2 = 109622

54,811 x one and two fourths = 82216.5

54,811 x 1 = 54811

54,811 x two fourths = 27405.5

The first, second, and third are 54811 multiplied by a number that is greater than or equal to 1. When a number is multiplied by something greater than 1, it gets bigger, and when multiplied by 1 it stays the same. The one where you have to mulitply by two fourths is multiplying by less than 1, so it gets smaller.

One electrician charges his customers a $60 service fee plus $35 per hour.

gavmur [86]

Answer:

2 hours; $130

Step-by-step explanation:

We can do this by setting up an equality since we are finding when they are the same. Say x is the number of horus:

65 * x = 60 + 35* x

30 * x = 60

x = 2 hours

The cost will be the same at two hours, and plugging it in, we can get 65*2=130.

If the teacher has 30 students and 10% left,how much students does she have now

garri49 [273]

Answer:

She has 27 students now.

Step-by-step explanation:

Given :

The teacher has 30 students

10% students left.

To find : how much students does she have now?

Solution :

Since we are given that teacher has 30 students .

And 10% of students left

⇒ 10% of 30

⇒ $\frac{10}{100} *30$

⇒ $\frac{300}{100}$

⇒ $3$

Thus, 3 students left .

She had 30 students . three students left.

So, now she have 30 - 3 = 27 students .

Hence she has 27 students now.

Help! Given that tanθ=-1, what is the value of secθ, for 3π/2<θ<2π?

user100 [1]

Answer: Choice B) $\sqrt{2}$

Work Shown:

$\sec^2(\theta) = \tan^2(\theta) + 1\\\\\sec^2(\theta) = (\tan(\theta))^2 + 1\\\\\sec^2(\theta) = (-1)^2 + 1\\\\\sec^2(\theta) = 2\\\\\sec(\theta) = \sqrt{2}\\\\$

Note: secant is positive in quadrant Q4, when theta is between 3pi/2 radians and 2pi radians (270 degrees and 360 degrees). So that's why we don't consider the minus form of the plus minus.
