Solve -4 b + 2 = 18.<br><br> b =

ahrayia [7]

Answer:

b = -4

Step-by-step explanation:

-4 b + 2 = 18

Subtract 2 from each side

-4 b + 2-2 = 18-2

-4b = 16

Divide by -4

-4b/-4 = 16/-4

b = -4

A telemarketer has 4 hours a day to call people for a survey. It takes 3 seconds to dial the number and each call takes 2 minute

schepotkina [342]

The telemarketer can make 117 calls per day

<em><u>Solution:</u></em>

Given that a telemarketer has 4 hours a day to call people for a survey

It takes 3 seconds to dial the number and each call takes 2 minutes

<u><em>To find: Number of calls made in 1 day</em></u>

From given statement,

Total number of hours = 4 hours

<em><u>Convert 4 hours to minutes</u></em>

1 hour = 60 minutes

4 hours = 4 x 60 = 240 minutes

Time taken to dial the number = 3 seconds

<em><u>Convert 3 seconds to minutes</u></em>

Use the following conversion factor

$1 \text{ second } = \frac{1}{60} \text{ minute }$

$3 \text{ second } = 3 \times \frac{1}{60} \text{ minute } = 0.05 \text{ minute }$

Thus,

Time taken to dial the number = 0.05 minute

Time taken for call = 2 minutes

Total number of time = 240 minutes

Let "x" be the number of calls made per day

Total number of time = x(Time taken to dial the number + Time taken for call)

Therefore, we get

240 minutes = x(0.05 minute + 2 minute)

240 = x(2.05)

2.05x = 240

$x = \frac{240}{2.05}$

x = 117

Thus 117 calls can be per day

Help me jim! geometry homework

Question 1

The angles 52 degrees match up. So if the sides are in proportion, then the triangles are similar.

Notice how 8/12 = 18/27 is a true equation. So the sides are in proportion to one another.

Therefore, the triangles <u>are similar</u>. I used the <u>SAS similarity theorem</u>.

================================================================

Question 2

Let's find the missing angle of the triangle on the right. For now, make that missing angle to be x.

Rule: For any triangle, the three angles always add up to 180

x+70+32 = 180

x+102 = 180

x = 180-102

x = 78

The missing angle of the triangle on the left is 78 degrees

Repeat for the other triangle as well

y+78+32 = 180

y+110 = 180

y = 180-110

y = 70

Both triangles have the angles 32, 70, 78 in whatever order you wish.

Since the angles match up like this, <u>the triangles are similar</u> because of the <u>AA Similarity theorem</u>

Technically, we only need 2 pairs of congruent angles at minimum. But having 3 congruent pairs doesn't hurt either.

================================================================

Question 3

We have a pair of congruent 54 degree angles shown. There's another pair of angles at the very top that overlap (aka shared angles).

Since we have two pairs of congruent angles, <u>the two triangles are similar</u>.

This time we use the <u>AA Similarity theorem</u>

================================================================

Question 4

Let's divide the longest side of the bottom triangle by the longest side of the triangle on top

48/32 = 1.5

Now let's divide the shortest sides of each triangle in the same order

36/24 = 1.5

Repeat for the middle-most sides

45/30 = 1.5

We get the same linear scale factor 1.5 each time. Therefore, <u>the triangles are similar</u> due to the <u>SSS Similarity theorem</u>

================================================================

Question 5

Any angle is equal to itself due to the <u>reflexive property</u>. So that will go for reason number 2.

Reason 3 is <u>SAS similarity</u> because we have the sides in proportion (statement 1) and the angles are congruent (statement 2).
