Answer:

x=17

Step-by-step explanation:

There are two congruent angles so we can double the given values and set that equal to 360. After setting that equal to 360 you find that x is equal to 17, then you plug that into the original equations and get your angles

Answer: 32

Step-by-step explanation: 4/2=2 16*2=32

Answer:

The line with a slope of 1/2 is steeper

Step-by-step explanation:

Here, we want to get which slope is steeper

mathematically, when we want to know the line that has a steeper slope, we compare the value of the slopes

The line with a slope that is of greater value will be steeper

Mathematically, 1/2 is a greater number than 1/3

That simply means 1/3 is less steep and thus, the line with the slope of 1/2 is the steeper line

Answer:

D

Step-by-step explanation:

The problem with D is that 7 + 11 = 18. The rule is any two sides must exceed the third. D gives the shorter + the middle length = the longest length.

That can't work. All the others are fine.

Answer:

-85

Step-by-step explanation:

We are given the equation [tex]E^8_{n=1}[/tex][tex](-2)^{n-1}[/tex] and are asked to evaluate it.

This can be solved using the geometric sequence, but first we have to determine our "r", "n", and [tex]a_{1}[/tex].

Of course [tex]a_{1}[/tex] is equal to 1. Therefore,

[tex]a_{1[/tex] = 1

[tex]r=[/tex]

[tex]n=[/tex]

(-2) is the change per number in the sequence, therefore -2 is our "r".

[tex]a_{1[/tex] = 1

[tex]r=-2[/tex]

[tex]n=[/tex]

The number "8" on [tex]E^8_{n-1}[/tex] represents the "n". Therefore 8 is our "n".

[tex]a_{1}=1[/tex]

[tex]r=-2[/tex]

[tex]n=8[/tex]

Use the geometric sequence sum formula and substitute :

[tex]a_{1} \frac{1-r^n}{1-r}[/tex]

[tex]1* \frac{1-(-2)^8}{1-(-2)}[/tex]

[tex]1* \frac{1-(-2)^8}{1+2}[/tex]

[tex]1* \frac{1-256}{1+2}[/tex]

[tex]1* \frac{-255}{3}[/tex]

[tex]1 * -85[/tex]

[tex]-85[/tex]

Answer:

Increase in surface area =  126 cm²

Step-by-step explanation:

Surface area of the rectangular prism has the dimensions as

Length = 42 cm

Width = 35 cm

Height = 64 cm

Total surface area of the rectangular prism = 2(lb + bh + hl)

Here, l = Length of the box

b = Width of rectangular box

h = height

Total surface area = 2(42×35 + 35×64 + 64×42)

= 2(1470 + 2240 + 2688)

= 12796 cm²

If height is increased by by 1.5 cm, new height of the box = 64 + 1.5 = 65.5 cm

Surface area of the box = 2(42×35 + 35×65.5 + 65.5×42)

= 2(1470 + 2240 + 2751)

= 12922 cm²

Increase in surface area = 12922 - 12796

                                          = 126 cm²

Answer:

-4, no real solutions

Step-by-step explanation:

b^2 is 16 since b is -4

4ac = 4*1*5 = 20

16 - 20 is -4

no real solutions since you cant get the squareroot out of a negative number (at least not real numbers)

Answer:B

Step-by-step explanation: The discriminant is −4, so the equation has no real solutions.

Answer:

4 + 3n

Step-by-step explanation:

Number of seed planed in his garden = 4

Let the Number of seed planted in each neighbor's garden = n

Number of neighbors he has = 3

The total number of seeds planted can be represented by the equation :

Number of seeds planted in his garden + (number of neighbors * number of seeds planted in each neighbors garden)

4 + 3n

Answer:

Step-by-step explanation:

Root:

n≈0.00833333 m + 0.666667

Root for the variable n:

n≈-0.0833333 (-0.1 m - 8)

Derivative:

Answer:

RT = 24

Step-by-step explanation:

Diagonals of rectangles bisects each other and equal in length (congruent) to each other.

Thus

US = RT

US = 2(RO)

4x - 16 = 2(x + 2)

4x - 16 = 2x + 4

2x = 20

x = 10

RT = 2(RO)

= 2(x+2)

= 2(10 + 2)

= 2(12)

= 24

Answer:

x = 24.75

Step-by-step explanation:

28/8 = 2x+3/15

420 = 16x +24

396 = 16x

x = 24.75

2(24.75) +3 =

49.5 + 3 = 52.5

Answer:

x=9

Step-by-step explanation:

let's find the scale factor of the enlargement ∆ABC of ∆ADE

k=28/20=7/5 or 1.4

Now k×|AD|=|AB|

Therefore

k×|DE|=2x+3

7/5×15=2x+3

21=2x+3

21-3=2x

2x=18

x=9

Answer:

6

Step-by-step explanation:

The remainder when 8 divides 894 is 6. So, she will be left with 6 flowers.

Answer:

a. Please find attached the plot of the points (0, 0) and (5, 15)

b. The point (0, 0) represents the start point

The point (5, 15) represents the point in the relationship between the water level and the change in time after 5 seconds

c. Please find attached the graph showing the Linear Trendline drawn between the points (0, 0) and (5, 15)

d. The line represents the possible combination time and water level during filling the bucket

e. The equation of the line is y = 3·x

Step-by-step explanation:

The rate at which the empty bucket is filled = 3 inches per second

a. Please find attached the plot made with Microsoft Excel of the points (0, 0) and (5, 15)

b. The points in part (a) (0, 0) and (5, 15) represent the following stages;

1) The point (0, 0) represents the point where the bucket is initially empty before filling the bucket with water

2) The point (5, 15) represents the 5 seconds of filling the bucket with water to a level of 15 inches

c) Please find attached the plot of the points with a Linear Trendline drawn between the points created with Microsoft Excel

d. The straight line drawn from point (5, 15) and passing through the origin at (0, 0) represents the proportional relationship between the water level in the bucket and the amount of time used in filling the bucket

e. The equation of the line is the equation of a proportional relationship which can be expressed in the following form;

y = kx

k = y/x

At the point (5, 15), we have;

y = 15, and x = 5

∴ k = 15/5 = 3 = The rate at which the bucket is filled with water

k = 3

Therefore, we have;

y/x = k = 3

∴ y/x = 3

y = 3 × x = 3·x

The equation of the line is therefore;

y = 3·x

The Triangle RST is missing, so i have attached it.

Answer:

A) TZ = 34

B) ZW = 17

C) SY = 69

D) XZ = 21

Step-by-step explanation:

To form the centroid, we see median drawn from the centre of all three sides.

Thus means the 3 sides are divided into 2 and as such;

XS = XT

YR = YT

WR = WT

Now, for median that forms centroid, the two parts are usually not the same length but instead in the ratio 2:1. That means one portion of the line segment is twice the length of the other.

Thus, by inspection of the given triangle, we can say that;

SZ = 2(ZY)

TZ = 2(ZW)

RZ = 2(XZ)

A) Now, we are given TW = 51

TW is made up of TZ and ZW

But since TZ : ZW = 2:1, it means that;

TZ = ⅔ × TW

TZ = ⅔ × 51

TZ = 34

B) From earlier, we saw that TZ = 2(ZW).

Thus; 34 = 2(ZW)

ZW = 34/2

ZW = 17

C) We are given ZY = 23.

From earlier, we saw that;SZ = 2(ZY)

Thus; SZ = 2(23)

SZ = 46

From the attached image we can see that;

SY = SZ + ZY

Thus;

SY = 46 + 23

SY = 69

D) We are given RZ = 42.

From earlier, we saw that;

RZ = 2(XZ)

Thus;

42 = 2(XZ)

XZ = 42/2

XZ = 21

Answer:

Answer is in picture and explanation below.

Step-by-step explanation:

Continuing from the picture,

Area of Metal base = Area of Bigger Circle - Area of Hollow Circle

=

[tex]1156\pi {mm}^{2} - 225\pi {mm}^{2} \\ = 931\pi {mm}^{2} [/tex]

Volume of Cylinder = Area of Metal base x Height (Length in this case)
