Use the graph shown to fill in the blank.

When x = 1, then y = a0.

Answers

Answer:

When x=1 then the value of y=-2.

Step-by-step explanation:

We are given that a line  on the graph

We have to find the value of  y when x=1

From given graph, the line intersect the x- axis x=3 .Therefore, the point is (3,0).The line intersect y- axis at -3 .Therefor, the point is (0,-3).

We can see that the line passing from (3,0),(2,-1),(1,-2) and (0,-3).

When x=1 then the value of y=-2.

Hence, y=-2 when x=1

Write which place to use when comparing the numbers 3,176 & 3,472

Answers

Answer:

Step-by-step explanation:

To compare 3,176 and 3,472 using the number line, remember how numbers appear on a number line:

Smaller numbers are to the left, and larger numbers are to the right.

but since both is in the 3,000 just make sure one is on the left and find out where the bigger one goes on the right

Answer:

The hundreds place

Step-by-step explanation:

To compare numbers we start from the left of each number. Both of these numbers have 4 digits. The leftmost digit is the thousands place.

3,176 & 3,472

The thousands places both show 3. Both numbers are 3 thousand and something. The thousands places are equal and are not enough to compare the numbers.

3,176 & 3,472

The hundreds places show a 1 and a 4. The digit 1 in the hundreds place means 100. The digit 4 in the hundreds place means 400. Since 4 is greater than 1, by comparing the digits in the hundreds place, we can already tell which number is greater.

Answer: The hundreds place.

The help desk is keeping track of the number of minutes the average caller spends on hold.

A 2-column table with 6 rows titled Average Time on Hold with Help Desk. The first column is labeled Week with entries 1, 2, 3, 4, 5, 6. The second column is labeled Average Time on Hold (minutes) with entries 7, 5, 3, 2, 3, 5.
According to the table, during which interval did the average time spent on hold increase?

week 1 to week 3
week 1 to week 4
week 4 to week 6
week 3 to week 5

Answers

Answer:

It would be week 4 through 6.

Step-by-step explanation:

This is because if you notice that during the first 4 weeks they drop and then week 5 and 6 they raise, which means it is 4 -  6 weeks.

Answer:

The correct option is C) week 4 to week 6.

Step-by-step explanation:

Consider the provided Table.

According to the given information.

Week        Average time on hold

  1                           7

  2                          5                        (Decrease -2)

  3                          3                        (Decrease -2)

  4                          2                        (Decrease -1)

  5                          3                        (Increase +1)

  6                          5                        (Increase +2)

If we observe the table we can find that from week 1 to week 4 average value decrease from 7 to 2.

But from week 4 to 6 the average value starts increasing. The average time  increase from 2 to 5.

Hence, the correct option is C) week 4 to week 6.

Find the measures of angle AOC and angle COB in the graph​

Answers

Final answer:

The measures of angles AOC and COB typically depend on the lengths of segments or other angles in the configuration. If points A, O, C, and B are on a circle with O as the center, the measures of these angles are related to the lengths of the arcs AC and BC. However, without a specific graphical representation, a precise answer cannot be provided.

Explanation:

Without any graphical representation, we could only suggest a general way to find the measures of Angle AOC and Angle COB. Regardless, in geometry, points A, O, and C usually represent vertices of an angle or a triangle. The measures of these angles could usually be calculated if the lengths of the connecting segments are known or if other angles in this configuration are known.

If 'O' were the center of the circle and 'A', 'C', and 'B' are points on the circle, the measures of angles AOC and COB depend on the measure of arc AC and BC respectively. These measures can be determined by the proportion of the arc length to the total circumference of the circle, multiplied by 360 degrees.

Based on the understanding of the 'points rotate through the same angle (AO)', information given, if both angles rotate through the same angle, then Angle AOC and Angle COB should be equal. However, without a specific graphical representation, it's hard to give a precise answer.

The measure of angle AOC is 45⁰.

The measure of angle COB is 45⁰

How to calculate the measure of angle AOC and COB?

The measure of the angles is calculated by applying trigonometry ratio as follows;

The measure of angle AOC is calculated as;

AOC = 90 - COB (complementary angles add up to 90 degrees)

The measure of angle COB is calculated as;

tan O = CB / OB

tan O = 5 / 5

tan O = 1

O = arc tan (1)

O = 45⁰

So angle COB = 45⁰

The measure of angle AOC is calculated as;

AOC = 90 - 45

AOC = 45⁰

Thirty copies of a textbook weigh a total of 75 lb. What is the weigh of each book?​

Answers

Answer: Each book weighs 2.5 pounds.

Step-by-step explanation: 75 divided by 2.5 is 30.  Or you could also get the answer by multiplying 30 and 2.5 which it would be 75. So, therefor, the answer is 2.5.

Final answer:

To find the weight of each textbook, we divide the total weight by the number of books. Therefore, each book weighs 2.5 lb.

m∠DHL = 83°

Step-by-step explanation:

Angle IHL and Angle DHL fall in a straight line. We know the measure of a straight line [straight angle] is 180°.

Thus, we can write:

∠IHL + ∠DHL = 180

97 + ∠DHL = 180

∠DHL = 180 - 97

∠DHL = 83°

Hence, m∠DHL = 83°

A glass pitcher is filled with water. 1/8 of the water is poured equally into 2 glasses.

b. If each glass has 3 fluid ounces of water in it, how many fluid ounces of water were in the full pitcher?
c. If 1/4 of the remaining water is poured out of the pitcher to water a plant, how many cups of water are left in the pitcher?

Answers

Answer:

Step-by-step explanation:

Part a)

Let the volume of water in glass pitcher be 'V'

Now it is given that 1/8 of water is poured in 2 glasses

Thus the volume of water in each glass is

[tex]V'=\frac{1}{2}\times \frac{V}{8}=\frac{V}{16}[/tex]

Part b)

Now it is given that volume of water in each glass is 3 fluid ounces thus to obtain the original volume we euate the volume obtained in part a with 3. Thus

[tex]\frac{V}{16}=3\\\\\therefore V=3\times 16=48ounces[/tex]

Part c)

After pouring out 1/8 water from the orifinal glass the volume of watre that remains in the pitcher euals

[tex]V_{rem}=V-\frac{V}{8}=\frac{7V}{8}[/tex]

Now since 1/4 of the above volume is poured out which euals

[tex]V_{poured}=\frac{1}{4}\times \frac{7V}{8}=\frac{7V}{32}[/tex]

Thus the volume of water that remains euals

[tex]V'_{rem}=\frac{7V}{8}-\frac{7V}{32}=\frac{21V}{32}[/tex]

Applying the value of V we get

[tex]V'_{rem}=\frac{21\times 48}{32}=31.5[/tex]ounces
