Answer 1

Answer:

C = 112, A = 150, D = 30, B = 38

Step-by-step explanation:

I solved C first using:

30+38+c = 180 (angles along a straight line should add up to 180 since a whole circle is 360)

-

I solved A by looking across from C.

Angles on opposite sides should mirror each other but A includes 38* + C

Just by doing 112 + 38 you get 150.

-

I solved D by looking at 30*, alternative interior angles are the same so D is 30*.

-

I solved B by taking C (112) and D (30) and adding them together and subtracting from 180.

Interior angles of a triangle should all add up to 180,

112 + 30 + B = 180

From this I got that B was 38.

Alternatively you can find this out by looking at the 38 degrees, corresponding congruent angles are always the same.

I suggest reviewing this angles sheet if you're ever stuck in the future.

Answers

Answer:

33.29

Step-by-step explanation:

A=πr^2

A=π2^2=12.57

12.57/2=6.29

7-4=3

3x2=6

6/2=3

4x6=24

6.29+3+24=33.29

Answer: 33.28 m^2

Semi-Circle:
Area = 0.5*(pi*radius^2) = 0.5(3.14*2^2) = 0.5(3.14*4)
= 6.28 m^2

Rectangle:
Area = length*width = 6*4 = 24 m^2

Triangle:
Area = 0.5(Base*Height) = 0.5(3*2) = 3 m^2

Total Area = 6.28 + 24 + 3 = 33.28 m^2

Ashin has been working in UAE for a decade and saved AED 125,500 which he wants to transfer now to his parent's account in India. Keeping in mind the AED – INR exchange rate for the day, which is AED 1 = 20 (approx.), find the amount of money which Arshad's parents will withdraw in India.

Answers

Answer:

2510000 INR

Step-by-step explanation:

Given

[tex]Savings = AED 125500[/tex]

[tex]1\ AED =20\ INR[/tex]

Required

The amount that will be withdrawn in India

We have:

[tex]1\ AED =20\ INR[/tex]

Multiply both sides by the savings

[tex]125500 * 1\ AED =20\ INR * 125500[/tex]

[tex]125500\ AED =125500 * 20\ INR[/tex]

So, we have:

[tex]125500\ AED =2510000\ INR[/tex]

Hence, the amount that will b withdrawn is: 2510000 INR

Answer:

13 5/8 Or 13.625


Explanation:

• Let’s start with 1/4. There are five days that has the amount of 1/4 of rainfall.

So we have to add all five of the 1/4 or just multiply:

1/4 x 5 = 5/4


• Now for the 3/8. There are twelve days that has that amount of rainfall.

3/8 x 12 = 36/8


• For 1/2. There are five days.

1/2 x 5 = 5/2


• For 5/8. There’s five days.

5/8 x 5 = 25/8


• Lastly for 3/4. There is three days.

3/4 x 3 = 9/4



• Now we add all of the amount together:

5/4 + 36/8 + 5/2 + 25/8 + 9/4


- To add, we have to find the Least Common Denominator (LCD), which is 8.

So we have to make all of the fractions into a denominator of 8 by multiplying:

5/4 —> 10/8 (Multiply by 2)

36/8 (Stays the same, already have the denominator of 8)

5/2 —> 20/8 (Multiply by 4)

25/8 (Stays the same, already have the denominator of 8)

9/4 —> 18/8 (Multiply by 2)


• Now add:

10/8 + 36/8 + 20/8 + 25/8 + 18/8 = 109/8


109/8 = 13 5/8

Or as decimal form: 13.625

20 people each bring 3 food dishes to an awards banquet. The dishes are shared equally by 180 people at the banquet. How many people share 1 food dish?

Answers

Answer:

3 people

Step-by-step explanation:

If 20 people each bring 3 food dishes to an awards banquet, the total amount of food brought will be (20 * 3) = 60foods

If the dishes are shared equally by 180 people at the banquet, then;

60foods = 180 people

1 food = x

Cross multiply

60* x = 180

60x = 180

x =180/60

x = 3

Hence 3 people will share 1 dish

What is the value of 2x^2+6x-9 when x = 3

Answers

Answer:

45

Step-by-step explanation:

We have the equation 2x² + 6x + 9 and are asked to find the value when x =3.

To solve this, all we need to do is substitute all variables with "x" to 3. Then do the properties :

2x² + 6x + 9

2(3)² + 6(3) + 9

Do exponents first :

2(9) + 6(3) + 9

Now multiply the numbers with parenthesis next to them :

18 + 18 + 9

Add to get the answer :

45

Answer:

27

Step-by-step explanation:

We have the equation:

2x^2+6x-9

If x = 3, we can substitute 3 in for the x values.

We get the equation:

2([tex]3^{2}[/tex]) + 6(3) - 9

Using PEMDAS:

First, evaluate the power.

3^2 = 9

Then, multiply the numbers.

2 x 9 + 6 x 3 - 9

We get:

18 + 18 - 9

Simplify.

18 + 18 = 36

36 - 9 = 27

Hope this helps.

what is the value of X in the diagram below

Answers

Answer:

18

Step-by-step explanation:

We will try to find the angle on the left side of the small triangle. So we have to use Tan.

SOHCAHTOA

TanФ = 12/8

[tex]Tan^{-1}[/tex] = 12/8   = 56.31°

So the other one is 33.69°  It's the top left one of the smaller triangle.

The top right side of the bigger triangle is 56.31 because they both add up to make 90°

Now that we have an angle of the bigger triangle we will find the x.

Tan 56.31 = x/12

x = 18
