Answer:

a = 20°

Step-by-step explanation:

The sum of the interior angles of a triangle = 180°

85° + 75° + a = 180°

160° + a = 180°

a = 180° - 160°

a = 20°

Hope this helps

Not proportional because the numbers jump around

Answer:

h = 24 ft

Step-by-step explanation:

A = 936 ft^2, b = 39 ft.

A = bh

Divide both sides by b:

h = A/b = 936 ft / 39 ft = 24 ft

Answer:

24 days

Step-by-step explanation:

Jogs every 4 days

Badminton every 6 days

If on a particular day, Ridzuan jogs in the

morning and plays badminton in the evening, how

many days later would he jog and play badminton

again on the same day?

Find the lowest common multiple of 4 days and 6 days

4 days = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52

6 days = 6, 12, 18, 24, 30, 36, 42, 48, 54

The lowest common multiple of 4 days and 6 days is 24 days

It would take Ridzuan 24 days before he would jog and play badminton again on the same day

Given:

Radius of the base of the cone = 12 in.

The slant height of the cone = 15 in.

To find:

The lateral surface area of the given cone.

Solution:

The lateral surface area of the cone is:

[tex]LA=\pi rl[/tex]

Where, r is the radius of the base of the cone and h is the slant height of the cone.

Putting [tex]r=12,h=15[/tex], we get

[tex]LA=\pi (12)(15)[/tex]

[tex]LA=180\pi[/tex]

The lateral surface area of the cone is 180π in ² and the missing value for the blank is 180.

Answer:

Lateral is 180π

SURFACE AREA IS 340π

Answer:

  $18.48

Step-by-step explanation:

If we assume the account earned simple interest, the amount is given by the formula ...

  I = Prt . . . . interest on principal P at annual rate r for t years

  1.155 = P·0.0125·5

  P = 1.155/0.0625 = 18.48

Jake initially deposited $18.48 as his principal.

_____

Additional comment

The amount $1.155 is an unusual specification for an amount of money. If you mean $1,155.00, then the principal amount is likewise multiplied by 1000: $18,480.

Answer:

6.7 seconds

Step-by-step explanation:

Juan= Paul-0.4

Paul=Terry+1.3

We can substitute Terry+1.3 for Paul since they are equal

juan=(Terry-0.4)+1.3

terry=5.8

juan=(5.8-0.4)+1.3

juan=6.7

Answer:

$4138.7

Step-by-step explanation:

P= $3,900

R= 2%

T or n= 3 years

compounded anually (yearly) so:

A= P(1+[tex]\frac{R}{100}^n[/tex])

A= 3900(1+[tex]\frac{2}{100}^3[/tex])

A= $4138.7

Answer:

189.27 ft²

Step-by-step explanation:

Find the area of the rectangle, then the semi-circle, then add the sums.

1.) Rectangle ▭

║A = lw

║A = 10 ⋅ 15

║A = 150

2.) Semi-circle◗

║A = [tex]\frac{1}{2}[/tex](πr²)

║A = [tex]\frac{1}{2}[/tex](π ⋅ 5²)

║A = [tex]\frac{1}{2}[/tex](78.54)

║A = 39.27

3.) Adding sums +

║150 + 39.27 = 189.27

[Your answer should be 189.27 ft²]

Answer:

Step-by-step explanation:

Let's do the obvious things first.

Right rectangle

w = 11

L = 17

Formula

Area = L * W

Area = 11 * 17

Area =                                                187

Left rectangle

W = 8

L = 11

Area = 8 * 11=                                      88

Middle Rectangle

W = 11

L = 15

Area = 11 * 15                                    165

Now we come to the triangles. It's not obvious what to do with them. You have to infer that one of the lets is 8 and the other is 15. You get the 8 from the width of the left rectangle (see above.)

There are 2 triangles

Area = 2 * 1/2 * l1 * l2

Leg 1 = 8

Leg2 = 15

Area = 2 * 1/2 (8 * 15)

Area =                                          120

Total  = 120 + 165 + 88 + 187 =    560

Unless you have an  E answer that is 560, my answer does not agree with any of the given answers. I would suggest that you ask your teacher how it is done. My method is correct.

Answer: [tex]x\geq 6[/tex]

Step-by-step explanation:

Given

[tex]g(x)=\sqrt{x-4}\\h(x)=2x-8[/tex]

Now, g of h i.e. [tex]g(h(x))[/tex]

Put h(x) in place of x in g(x)

[tex]\Rightarrow g(h(x))=\sqrt{(2x-8)-4}\\\\\Rightarrow g(h(x))=\sqrt{2x-12}[/tex]

Now, the value inside square root must be greater than zero

[tex]\Rightarrow 2x-12\geq 0\\\\\Rightarrow 2x\geq 12\\\\\Rightarrow x\geq 6[/tex]

Answer:

178  1/2  inches cube

Step-by-step explanation:

Volume = length * width * height

           = 8 1/2  * 5 1/4  *  4

           =  17/2  * 21/4    * 4

            = 1428 / 8

             =357/2

          = 178  1/2  inches cube.

Answer:

0.964

Step-by-step explanation:

Answer:

Step-by-step explanation:

So we know that a straight line adds up to 180 degrees.

This means that:

52+59+y = 180

y + 111 = 180

y = 69

We also know a triangle also adds up to 180 degrees.

This means that:

y+x+63 = 180

69+63+x = 180

x + 132 = 180

x = 48

Answer:

y is 13 and x is 14

Step-by-step explanation:

because 13-10= 3 and 19-14=5

Length & breadth of the aquarium = 40cm(as it is square)

Volume of aquarium = l x b x h

volume of aquarium = 40 x 40 x 50 = 80000 cm³

Volume of water = ½ half of aquarium

Volume of water = ½ x 80000 = 40000 cm³

Volume of the solid cube = a³ = (20cm)³ = 8000cm³

Surely, 40000>>>8000, level doesnt reach the top of the tank.

Volume ocquired = 40000+8000=48000 cm³

Now, let it has reached reached a height h from the ground(bottom).

Volume = 48000 => lx b x h = 48000

=> 40 x 40 x h = 48000

=> h = 30 cm

The height at which water has reached is 30 cm(from bottom).

Thus, below the top it has reached = total height - 30 cm = 50 - 30 = 20 cm
