The following are the temperatures in °C for the first 10 days in January:
-4.2, -7.6, -2.3, -6.4, -3.3, 5.4, -7.7 ,-8.2 ,1.6 ,8.6
Calculate the range.

Answer:

3 yards

Step-by-step explanation:

First, let's convert yards into feet. 189 feet is 63 yards.

Volume=L•W•H           L=length W=width H=height

To do this we have to divide the volume by the product of the length and width and it will calculate the height.

Solving for the width:

63÷(7•3)=3 yards <-the depth of the pool

Answer:

3 yards

Answer:

0.358

Step-by-step explanation:

cos A=28/53 = 58.11

sin B=60/61 = 79.61

sin(79.11 - 58.11) = sin 21 = 0.358

Answer:

This would be graph A

Step-by-step explanation:

The graph decreases means the line goes down. crosses at -7 means the y intercept is -7 and then remains constant means a horizontal line

This would be graph A

Answer:

Graph A ; Option B

Step-by-step explanation:

Consider the criteria for the graph;

[tex]Criteria;\\\\Crosses Y - axis at Point - ( 0, - 7 ),\\Decreases Before Crossing Y - axis,\\Remains Constant after Crossing Y - axis,\\[/tex]

Now take a look at each option before us;

[tex]Graph A - \\1. Travels Down,\\2. Crosses Y - axis at Point ( 0, - 7 )\\3. Remains Constant\\\\Graph B - \\1. Travels Upward,\\2. Crosses Y - axis at Point ( 0, 7 )\\3. Remains Constant\\\\Graph C - \\1. Travels Down,\\2. Crosses Y - axis at Point ( 0, - 7 )\\3. Travels Upward[/tex]

Comparing the three, we conclude that Graph A meets the provided criteria, which confirms that it is the right answer;

[tex]Solution ; Graph A[/tex]

Answer:

B

Step-by-step explanation:

Well since it is arthimetic sequence we know the formula

We know d is difference between second term and first so it will be -5- (-12)= -5+12= 7

[tex]a_{n}= a _{1}+ d (n-1) \\a_{n}= -12+7(n-1)\\a_{n} = -12+7n-7\\a_{n}= 7n-19[/tex]

the domain of this is 1,2,3,4.......

range is -12,-5,2,9.......

Therefore answer is B.

Answer:

Relative frequency is 7.41% or 0.0741

Step-by-step explanation:

Given

The Attached Table

Required

Calculate the relative frequency of the class with lower limit 27

Relative Frequency is calculated by dividing individual frequency by the total frequency

Mathematically,

[tex]Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}[/tex]

The total frequency of the given data is 6+8+4+2+5+2

[tex]Total\ Frequency = 27[/tex]

The class with lower limit 27 has a frequency of 2;

Hence;

[tex]Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}[/tex] becomes

[tex]Relative\ Frequency = \frac{2}{27}[/tex]

[tex]Relative\ Frequency = 0.07407407407[/tex]

[tex]Relative\ Frequency = 0.0741[/tex] (Approximated)

You may also leave your answer in percentage form

[tex]Relative\ Frequency = 0.0741 * 100\%[/tex]

[tex]Relative\ Frequency = 7.41 \%[/tex]

Hence, the relative frequency is 7.41% or 0.0741

Hi!

So the first thing to do is to combine the common terms on each side.

On the left side, 13 and 2a cannot be put together because 2 has a multiplier that 13 does not.

On the right side, however, there are two numbers with the multiplier a. Add those together!

3a + 2a = 5a.

13 + 2a = 5a - 14

Now we want to isolate a to one side. Let's do the right side.

To do this, we have to subract 2a from both sides to get a on only one side.

13 + 2a - 2a = 5a - 2a - 14.

Subract.

13 = 3a - 14.

We have to do the same for the 14 on the right side. Instead, since the number is being subracted from 3a, we have to add it to both sides.

13 + 14 = 3a + 14 - 14.

27 = 3a

a = 9.

Answer:

78 degrees

Step-by-step explanation:

x=108-30 PWP (Part Whole Postulate)

x=78         Solve

Answer:

See solution ( s ) below;

Step-by-step explanation:

1 . Consider the first attachment;

[tex]m< ( unknown ) = 30 degrees, - Given\\m< ( unknown ) = 108 degrees - Given,\\\\\\m< ( unknown ) + x = m< ( unknown ) - By Partition Postulate,\\30 + x = 108, - Through Algebra,\\Conclusion ; ( x = 78 degrees )[/tex]

Solution ; x = 78°

From a horizontal position, in reality we could only bed our knee to a maximum of a little less than 180 degrees. However, let's consider the max Randi can bend her leg as 180° ;

[tex]By Partition Postulate - 108 + x = 180,\\if x - degrees Randi Can Bend more,\\108 + x = 180,\\\\Conclusion ; ( x = 72 degrees )[/tex]

Solution ; Randi can bed her knee 72° further

3 . Consider 3x and 8x + 15 to be a linear pair,

[tex]3x + ( 8x + 15 ) = 180 - Linear Pair,\\\\3x + 8x + 15 = 180,\\11x + 15 = 180,\\11x = 165,\\Conclusion ; ( x = 15degrees)[/tex]

Solution ; x = 15°

Answer:

[tex] = 15 {x}^{2} + x - 2 \\ [/tex]

Step-by-step explanation:

[tex](3x - 1) \times (5x + 2) \\ 3x(5x + 2 ) - 1(5x + 2) \\ 15 {x}^{2} + 6x - 5x - 2 \\ = 15 {x}^{2} + x - 2[/tex]

Given:

To find out:

Find the area ?

Solution:

Area = ( 3x - 1 ) × ( 5x + 2 )

= 3x ( 5x + 2 ) - 1 ( 5x + 2 )

= 15x² + 6x - 5x - 2

= 15x² + x - 2

Thus, the area is 15x² + x - 2 .

Answer:

x = -1 <--- axis of symmetry

(-1, -9) <-- vertex

2, -4  (or, in my old precalc class we wrote our roots as (2,0) and (-4,0))   <--- roots

Step-by-step explanation:

a) Axis of symmetry equation is defined as

[tex]-b/2a[/tex] = x  (i memorized this)

Quadratic equation form:

[tex]ax^2+bx+c[/tex]

And our original equation:

[tex]x^2+2x-8[/tex]

So..

[tex]-2/2 = - 1[/tex]

So our axis of symmetry is at x = -1,

b) now vertex point can be found by plugging this value back into our original equation.

y = [tex](-1)^2+2(-1)-8[/tex]

y = 1 - 2 - 8

y = - 9

So our vertex is at (-1, -9)

c) Finally, lets factor

[tex]x^2+2x-8[/tex] = 0  (when finding the roots, set y = 0, because we are trying to find where we cross the x-axis)

[tex]x^2-2x+4x-8[/tex] = 0

[tex]x(x-2) + 4(x-2) = 0[/tex]

[tex](x-2)(x+4)=0[/tex]

x = 2; x = -4 <--- Roots

Answer:

Correct option: first one

Step-by-step explanation:

If we reflect the triangle RST over the x-axis, the y-coordinate of each point will have the sign switched, so the point S would be in (1, -5), the point R would be in (1, -1) and the point T would be in (4, -1)

Then, if we translate the resulting points 2 units to the left, we would have:

S = (-1, -5) -> matches point C

R = (-1, -1) -> matches point A

T = (2, -1) -> matches point B

So the triangles are congruent, and we can map from triangle RST to triangle ACB with a reflection over the x-axis and a translation of 2 units to the left.

Correct option: first one

Answer:

y[tex]\leq[/tex][tex]\frac{1}{3}[/tex]x-4; B

Step-by-step explanation:

The blue is in the y-values where it is more directed towards the negative y- values.

y=mx+b

[tex]\frac{1}{3}[/tex] slope= because rise is 1 and 3 runs and to find slope it is [tex]\frac{rise}{run}[/tex]

-4 is the "b" in y=mx+b where b represents the y-intercept and looking at the graph, the line intercepts at -4  

Answer:

a = 4.5 units

b = 7.5 units

Step-by-step explanation:

By using mean proportional theorem in the ΔACB,

ΔACB ~ ΔADC ~ ΔCDB

[tex]\frac{AD}{CD}=\frac{CD}{DB}[/tex]

[tex]\frac{8}{6}=\frac{6}{a}[/tex]

a = [tex]\frac{6\times 6}{8}[/tex]

a = 4.5

[tex]\frac{AB}{CB}=\frac{CB}{DB}[/tex]

[tex]\frac{(a+8)}{b}=\frac{b}{a}[/tex]

Since a = 4.5

[tex]\frac{4.5+8}{b}=\frac{b}{4.5}[/tex]

b² = 4.5 × 12.5

b = √56.25

b = 7.5 units

Therefore, a = 4.5 units and b = 7.5 units will be the answer.

Answer:

70 ft

Step-by-step explanation:

260 feet around its edge  means perimeter

P = 2(l+w)

Width = 60

260 = 2( l+60)

Divide each side by 2

260/2 = 2/2(l+60)

130 = l+60

Subtract 60 from each side

130-60 = l+60-60

70 = l

The length is 70 ft

You can clearly see that those angles have a square between them , thus they are right angkes

Answer:

-The Relationship:

Both [tex]\angle 2[/tex] and the [tex]18\textdegree[/tex] angle are supplementary.

The measure of [tex]\angle 2[/tex]:

[tex]\angle 2 = 162\textdegree[/tex]

Step-by-step explanation:

-The relationship about both [tex]\angle 2[/tex] and the [tex]18\textdegree[/tex] angle, is that they are supplementary, which they both add up to [tex]180\textdegree[/tex].

-To find the measure of [tex]\angle 2[/tex], you need to subtract [tex]18[/tex] from [tex]180[/tex] to get the actual angle measurement of [tex]\angle 2[/tex]:

Finding the measure of [tex]\angle 2[/tex]:

[tex]180 - 18 = 162[/tex]

[tex]\angle 2 = 162\textdegree[/tex]

So, now you have the measure of [tex]\angle 2[/tex] .

Answer:

It would take Abigail six days to read 32,400 words of a book if she were to read 30 minutes per day.

Step-by-step explanation:

If Abigail reads 180 words per minute, and she reads 30 minutes per day, we need to multiply 180 by 30 to figure out how many words she reads per day.

180 × 30 = 5,400

Abigail reads 5,400 words per day.

Then, we divide 32,400 by 5,400 to figure out how many days it would take Abigail to read 32,400 words.

32,400 ÷ 5,400 = 6

It would take Abigail six days to read 32,400 days.
