Answer:

659.82m^3

Step-by-step explanation:

Given data

Height= 5 m

Radius= 3m

The expression for the surface area is given as

SA= 2πr^2+2πrh

SA= 2*31.42*3^2+ 2*3.142*3*5

SA= 2*31.42*9+ 2*3.142*3*5

SA= 565.56+ 94.26

SA= 659.82m^3

Hence the volume of the 659.82m^3

Answer:

88.2          

Step-by-step explanation:

1) Find d

-20 = d + 6      original equation

-20 - 6 = d        subtract 6 from both sides to isolate the variable

-26 = d             simplify like terms

d = -26             answer

2) Plug it in expression

5 - 3.2d             original expression

5 - 3.2 (-26)       substitute value d for -26 (as calculated above)

5 + 83.2        PEMDAS (multiply first...don't subtract 5-3.2 and then multiply!)

88.2           simplify like terms and here is your answer

Answer:

5x+4=-6

5x=-6-4

5x=-10

x=-10/5

x=-2

Step-by-step explanation:

Answer:

[tex] \sf \: x = - 2[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 5x + 4 = -6

Then the value of x will be,

→ 5x + 4 = -6

→ 5x + 4 - 4 = -6 - 4

→ 5x + 0 = -10

→ 5x = -10

→ 5x ÷ 5 = -10 ÷ 5

→ [ x = -2 ]

Hence, the value of x is -2.

Answer:

The total area is 594cm.²

Step-by-step explanation:

The top and bottom each have a length of 36 cm.

Blue side:

36/3= 12cm. (36/3 for the length of one side of a blue square)

12*12= 144cm.² (area of one blue square)

144*3= 432cm.² (area of all the blue squares)

Orange side:

36/8= 4.5cm. (the length of one side of an orange square)

4.5*4.5= 20.25cm.² (the area of one orange square)

20.25*8= 162cm.² (the area of all the orange squares)

Total area:

432+162= 594 cm.²

I hope this makes more sense, have a great day :D

Answer:

(6, 3)

Step-by-step explanation:

Note that the opposite side of parallelogram are congruent, hence;

Jk = LM

2y + 3 = 5y - 6

2y - 5y  =-6 - 3

-3y = -9

y = 9/3

y = 3

Similarly;

KL = JM

8x – 10 = 3x+20

8x - 3x =  20 + 10

5x = 30

x = 30/5

x = 6

Hence (x,y) is (6, 3)

B.

Step-by-step explanation:

Answer:

-42

Step-by-step explanation:

Which expression is equivalent to 14 x minus 21 over 7 ?

Mathematically this expression is written as:

= (14 × -21)÷ 7

= (14 × -21)/7

= - 294/7

= -42

Therefore, the equivalent of the above expression is calculated as -42

Answer:

38°

Step-by-step explanation:

The measure of angle NPM is 38°.

➠ ∠MPJ + ∠LPM = 180°

➠ ∠MPJ + 90° = 180°

➠ ∠MPJ = 180° – 90°

➠ ∠MPJ = 90°

∠NPM = ∠MPJ – ∠JPN

➠ ∠NPM = 90° – 52°

➠ ∠NPM = 38°

Answer:

I am pretty sure it is (-2,8) and (2,-8)

Step-by-step explanation:

I think my answer is correct because it goes from Quadrant 1 into 4. Other answers are just I quadrant away.

Answer:

1.

d - adjacent

e - hypotenuse

f - opposite

2.

[tex]\sin \theta = \frac{12}{13},\\\\\cos \theta = \frac{5}{13},\\\\\tan \theta = \frac{12}{5},[/tex]

Step-by-step explanation:

1. The opposite side of an angle is the side that the angle faces or forms. The hypotenuse of a right triangle is always the longest side of the right triangle. The adjacent side is one side or leg next to the angle that is not the hypotenuse.

2. In right triangles only:

The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)

The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)

Thus, we have:

[tex]\sin \theta = \frac{12}{13},\\\\\cos \theta = \frac{5}{13},\\\\\tan \theta = \frac{12}{5},[/tex]

Answer:

Yes

Step-by-step explanation:

For every one x value is equal to one y value, therefore it's a one-to-one function.

Total number of sports students = 65

Total number of music/drama students = 25

Total number of work students = 10

Total number of students = 65 + 25+ 10 = 100

Probability = Total number of favourable outcomes/Total number of outcomes

Probability of picking a sports student = 65/100 = 13/20

Therefore, probability of picking a sports student is 13/20

Answer:

2 1/3 hours or 2 hrs, 20 min

Step-by-step explanation:

1 5/6 + 1/2

make mixed number into improper fraction and change 1/2 to 3/6

11/6 + 3/6 = 25/6

14/6 equals 2 2/6 which simplifies to be 2 1/3 or 2 hrs, 20 min

Answer:

its -4 :)

Step-by-step explanation:

Answer:

Its the green answer

Step-by-step explanation:

- The asymptote is on x=4 so with that we can rule out blue and red.

- the range is shown on the x-axis so it‘s green.

Answer:

Red

Step-by-step explanation:

The range of a function is the set of all of its y values. We can notice that the equation has a horizontal asymptote of y = -3, which basically means the value of y cannot be -3. So, it would be expressed as:

-∞ < y < -3 and -3 < y < ∞

This is the red option.

x = 73.21

Step-by-step explanation:

Consider triangle ABC. Since angle A is 45° and side BC is 100, then side AB is also 100.

Now consider triangle ABD. With angle A equal to 60°, we can use the definition of tangent to find the value of x:

tan 60 = BD/AB

sqrt(3) = (x + 100)/100

or

x + 100 = 100sqrt(3)

x = 100[sqrt(3) - 1]

= 73.21

Her 24 monthly payments total 24 x $56 = $1344

That means that $1344 - $1200 = $144 is just interest.  What percent is this of her loan amount?  Divide to find out:

144 / 2400 = 0.06 = 6%

Answer:

Amount of water left = 25 / 8 cups

Step-by-step explanation:

Given:

Amount of water teacher Sara have = [tex]6\frac{7}{8}[/tex] cups = 55 / 8 cups

Amount of water teacher used = 4/8 cups

Amount of water used by student = [tex]3\frac{2}{8}[/tex] cups = 26 / 8 cups

Find:

Amount of water left

Computation:

Amount of water left = Amount of water teacher Sara have - [Amount of water teacher used + Amount of water used by student]

Amount of water left = [55/8] - [4/8 + 26/8]

Amount of water left = [55/8] - [30/8]

Amount of water left = [55-30] / 8

Amount of water left = 25 / 8 cups
