Help me out from a through c (geometry/angle bisectors)

Answer:

[tex]\boxed {\boxed {\sf 750 \ Joules}}[/tex]

Step-by-step explanation:

Kinetic energy can be found using the following formula.

[tex]E_k=\frac{1}{2}mv^2[/tex]

where m is the mass and v is the speed.

We know this is a15 kilogram mass moving with a speed of 10 meters per second. Therefore:

[tex]m= 15 \ kg \\v= 10 \ m/s[/tex]

Substitute the values into the formula.

[tex]E_k=\frac{1}{2}(15 \ kg)(10 \ m/s)^2[/tex]

Solve the exponent first.

[tex]E_k=\frac{1}{2}(15 \ kg)(100 \ m^2/s^2)[/tex]

Multiply 100 m²/s²and 15 kg.

[tex]E_k=\frac{1}{2}(1500 \ kg*m^2/s^2)[/tex]

Multiply by 1/2 or divide by 2.

[tex]E_k= 750 \ kg*m^2/s^2[/tex]

[tex]E_k= 750 \ J[/tex]

The kinetic energy is 750 Joules.

Complete Question

A person standing 213 feet from the base of a church observed the angle of elevation to the church's steeple to be 33 ∘. Find the height of the church

Answer:

138.3 ft

Step-by-step explanation:

We solve this question above using using the Trigonometric function of Tangent.

tan θ = Opposite/Adjacent

Where:

Opposite = Height of the church = x

Adjacent = Distance for the base of the church = 213ft

Angle of elevation θ = 33°

Hence:

tan 33 = x /213 ft

Cross Multiply

x = tan 33 × 213 ft

x = 138.32381735 ft

x = Opposite Approximately = 138.3 ft

Therefore, the height of the church = 138.3 ft

Given that,

Four roommates share the cost of an apartment: rent, electricity, and gas. Rent costs $1200/month and gas costs $50/month. Each roommate pays $345/month.

To find,

The electric bill per month.

Solution,

Bill of each roommates = $1200+$500+E, E is electricity bill

Total bill = $345/month

Bill of each roommates = 4($1200+$500+E), E is electricity bill

ATQ,

4($1200+$500+E) = $345

So, the correct option is (c).

Answer:

I think it would be 16/15.

Step-by-step explanation:

6- 3/4x + 1/3 = 1/2x +5

6+ 1/3 - 5 = 1/2x + 3/4x

18/3 + 1/3 - 15/3 = 2/4x + 3/4x

18 + 1 - 15 / 3 = 2x + 3x / 4

4 / 3 = 5x / 4

4 × 4 / 3 = 5x

16/ 3 = 5x

16 / 3 ×5 = x

16 / 15 = x

Therefore, x = 16/ 15

Answer:

13,841,287,201

Step-by-step explanation:

simply the parenthesis:

7^6 or 7 times itself 6 times: 7x7x7x7x7x7

which equals 117,649 and then multiply that number by itself

117,649x117,649 and you should get 13,841,287,201

The simplification of  (7^6)^2 is 13,841,287,201

power defines a base number raised to the exponent, where base number is the factor which is multiplied by itself and exponent denotes the number of times the same base number is multiplied.

Given:  (7^6)^2

Firstly,

7 times itself 6 times

= 7x7x7x7x7x7

= 117,649

Now, 2 times of  117,649.

= 117,649x117,649

=13,841,287,201

Hence, the solution to this expression is: 13,841,287,201

I think answer is 32 blankets. 2 days will it takes

Answer:

Largest AREA A = x × y = 250 × 500/3 = 125000 / 3 = 41666.67 ft²

Dimensions; X = 250 ft and Y = 500/3 ft

Step-by-step explanation:

Given the data in the question;

2x + 3y = 1000 -------- EQU 1

2x = 1000 - 3y

x = 500 - 3y/2

AREA = x × y = (500 - 3y/2)y

= 500y - 3/2y²

dA/dxy = 500 - 3y = 0

3y = 500

y = 500/3

so from equ 1

2x + 3(500/3) = 1000

2x = 1000 - 500

x = 250

So; Largest AREA A = x × y = 250 × 500/3 = 125000 / 3 = 41666.67 ft²

Dimensions; X = 250 ft and Y = 500/3 ft

Answer:

36 customers, 6 guides

Step-by-step explanation:

Given: We know that the total number of guides and customers combined is 42 people, and the ratio of customers to guides is 6/1 (Every 6 customers, there's 1 guide)

So how do we solve this?

One way you can solve this is by making a column. On one side, you put 6, and on the other, you put 1.

Here's an example (obviously, making a column with a keyboard is quite difficult):

6 | 1

What's 6+1?

7.

Now, we need to figure out how many groups of 7 can go into 42.

We can figure that out by dividing 42/7, which gives you 6.

So now let's go back to that column:

6 | 1

Since we know 6+1=7, we can make 6 rows of it:

6 | 1

6 | 1

6 | 1

6 | 1

6 | 1

6 | 1

We know that on the column 6 represents the customers, and 1 represents the guides. So, all we have to do left is either add or multiply (whichever you prefer). I'll show both ways:

Multiplying

We can multiply 6x6 for the left column to get 36. That's how many customers we have. And for the guides, we can multiply 6x1 and get 6. So now we know we have 36 customers and 6 guides.

Adding

On the left side of the column, we have six rows of 6. In order to figure out the amount of customers, all we need to do is add 6 six times. It should be like this:

6+6+6+6+6+6=36

To figure out the guides, we do the same thing, but instead of adding 6 six times, it's 1. (Hopefully for this, you won't need to rely on repeated addition. It's a lot easier to count for 1)

1+1+1+1+1+1=6

So now we know there are 36 customers and 6 guides.
