Answer:

[tex] 6.3 \le p \le 8.1 [/tex]

The third reading must be between 6.3 and 8.1 inclusive.

Step-by-step explanation:

To find the average of three numbers, add the three numbers and divide by 3.

Let the third reading = p.

The average of the three readings is

[tex] \dfrac{7.4 + 7.9 + p}{3} [/tex]

This average must be between 7.2 and 7.8 inclusive. "Inclusive" means that the values 7.2 and 7.8 are allowed. That means the average must be greater than or equal to 7.2 and less than or equal to 7.8. We can write this as the following inequality.

[tex] 7.2 \le \dfrac{7.4 + 7.9 + p}{3} \le 7.8 [/tex]

Simplify the numerator.

[tex] 7.2 \le \dfrac{15.3 + p}{3} \le 7.8 [/tex]

Multiply the three sides by 3.

[tex] 21.6 \le 15.3 + p \le 23.4 [/tex]

Subtract 15.3 from the three sides.

[tex] 6.3 \le p \le 8.1 [/tex]

Answer: The third reading must be between 6.3 and 8.1 inclusive.

Answer:

5 negative tiles and 5 negative tiles

Step-by-step explanation:

When multiplying a positive number by a negative number, the product is always negative.

This can be visualized using integer tiles:

Answer:

So lets say the negative tiles are red and the poiitive tiles are yellow.

Now for the first one

2*-5

That would be shown with two groups of fives with red tiles

Now we know its -10 be used if you count it up, its 10 negatives red tiles

-2*5

So 5 groups of 2 red tiles and if you count it all up, you’ll get -10

-5*-5

So 5 groups of -5 tiles

You’d get -25

But thats not the answer

I have no clue to show this but i guess you just have to know that negative *negative is positive so just switch the signs

25

5*5

Just make 5 groups of 5 yellow tiles and count them up, you’ll get 25

Answer:

102 1/3 swimmers

Step-by-step explanation:

Let

Number of swimmers on Tuesday = x

Number of swimmers on Monday = 2x

Number of swimmers on Wednesday = 3x - 11

Total swimmers for all 3 days = 625

x + 2x + (3x - 11) = 625

3x + 3x - 11 = 625

6x = 625 - 11

6x = 614

x = 614 / 6

= 102 2/6

x = 102 1/3 swimmers

Number of swimmers on Tuesday = x = 102 1/3 swimmers

Number of swimmers on Monday = 2x

= 2(102 1/3)

= 204 2/3

Number of swimmers on Wednesday = 3x - 11

=3(102 1/3) - 11

= 307 - 11

= 296

Answer:

depth, latitude, and seasons

Step-by-step explanation:

Three causes for water temperature variation in ocean water are depth, Latitude, and season. Then the correct option is A.

Surface water temperature depends on latitude and season. The temperature of the surface water in the ocean changes from place to place and from season to season.

Ocean temperature depends on the amount of solar energy absorbed. For example, tropical oceans receive a lot of direct overhead sunlight for much of the year, so the water is warm.

The temperature of the surface waters varies mainly with latitude. For example, The polar seas which are found in high latitude can be as cold as -2 degrees Celsius while the Persian Gulf which is in low latitude can be as warm as 36 degrees Celsius.

Hence, the correct option is A.

SAS Similarity

Answer:

y = 6

Step-by-step explanation:

First find the value of x

Since given triangles are congruent,

Therefore measures of corresponding sides will be equal.

4x + 1 = 13

4x = 13 - 1

4x = 12

x = 12/4

x = 3

Next,

2x + y = 8x - 2y

y + 2y = 8x - 2x

3 y = 6x

3y = 6*3 (plug x = 3)

3y = 18

y = 18/3

y = 6

x = 2

5x + 10 x = 18 + 12

15x = 30

x = 2

Answer:

65

Step-by-step explanation:

If 100% they probably produce exact 50 of it everyday

so we need to find 30%

30/100 × 50 = 15

100% + 30% = 130%

50 + 15 = 65

Answer:

a) The height of the small object 3 seconds after being launched is 2304 feet.

b) The small object ascends 128 feet between 5 seconds and 7 seconds.

c) The object will take 6 and 10 seconds after launch to reach a height of 2640 feet.

d) The object will take 21 seconds to hit the ground.

Step-by-step explanation:

The correct formula for the height of the small object is:

[tex]h(t) = -16\cdot t^{2}+256\cdot t+1680[/tex] (1)

Where:

[tex]h[/tex] - Height above the ground, measured in feet.

[tex]t[/tex] - Time, measured in seconds.

a) The height of the small object at given time is found by evaluating the function:

[tex]h(3\,s)= -16\cdot (3\,s)^{2}+256\cdot (3\,s)+1680[/tex]

[tex]h(3\,s) = 2304\,ft[/tex]

The height of the small object 3 seconds after being launched is 2304 feet.

b) First, we evaluate the function at [tex]t = 5\,s[/tex] and [tex]t = 7\,s[/tex]:

[tex]h(5\,s)= -16\cdot (5\,s)^{2}+256\cdot (5\,s)+1680[/tex]

[tex]h(5\,s) = 2560\,s[/tex]

[tex]h(7\,s)= -16\cdot (7\,s)^{2}+256\cdot (7\,s)+1680[/tex]

[tex]h(7\,s) = 2688\,s[/tex]

We notice that the small object ascends in the given interval.

[tex]\Delta h = h(7\,s)-h(5\,s)[/tex]

[tex]\Delta h = 128\,ft[/tex]

The small object ascends 128 feet between 5 seconds and 7 seconds.

c) If we know that [tex]h = 2640\,ft[/tex], then (1) is reduced into this second-order polynomial:

[tex]-16\cdot t^{2}+256\cdot t-960=0[/tex] (2)

All roots of the resulting equation come from the Quadratic Formula:

[tex]t_{1} = 10\,s[/tex] and [tex]t_{2}= 6\,s[/tex]

The object will take 6 and 10 seconds after launch to reach a height of 2640 feet.

d) If we know that [tex]h = 0\,ft[/tex], then (1) is reduced into this second-order polynomial:

[tex]-16\cdot t^{2}+256\cdot t +1680 = 0[/tex] (3)

All roots of the resulting equation come from the Quadratic Formula:

[tex]t_{1} = 21\,s[/tex] and [tex]t_{2} = -5\,s[/tex]

Just the first root offers a solution that is physically reasonable.

The object will take 21 seconds to hit the ground.

Answer:

Simplifying

X + -4 = 2x

Reorder the terms:

-4 + X = 2x

Solving

-4 + X = 2x

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + X = 4 + 2x

Combine like terms: -4 + 4 = 0

0 + X = 4 + 2x

X = 4 + 2x

Simplifying

X = 4 + 2x
