I NEED AN ANSWER ASAP A Surveyor Finds The Angle Of Elevation To The Top Of A Building To Be 75. He Is

Answers

Answer 1

Answer: 74.6

we draw a right triangle ABC, have: ∠ABC = 90°,  AB = 20 and ∠BAC = 75°, the height of the building is BC

we also have: tan 75° = BC/AB = BC/20

=> BC = tan 75°. 20 = 40 + 20√3 ≈ 74.6

Step-by-step explanation:

Find the degree measure of each angle in tbr triangle

Answers

Answer: ∠p = 85; ∠Q = 72; ∠R = 23

have: m∠P + m∠Q + m∠R = 180°

=> 4x - 7 + 3x + 3 + x = 180°

⇔ 8x - 4 = 180

⇔ x = (180 + 4)/8

⇔ x = 23

=> m∠P = 4.23 - 7 = 85°

m∠R = 23°

m∠Q = 3.23 + 3 = 72°

The signed number to represent both situations are - 18 and + 5 respectively.

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, The temperature fell by 18 degrees Fahrenheit today.

Assuming the change in temperature is [tex]T_f[/tex] and initial temperature is [tex]T_i[/tex].

The tem[parature change can be represented by,

[tex]T_f = T_i - 18.[/tex]

Or - 18°F

Ali received 5 dollars, Assuming he had x dollars and after receiving he has now y dollars,

∴ The signed number represents this change.

y = x + 5.

Or + 5.

What is the value of x?

Answers

Answer:

Step-by-step explanation:

Use the exterior angle theorem, which states that the 2 opposite interior angles add up to the measure of the exterior angle.

Set up an equation:

(8x - 13) + (9x - 10) = 11x + 13

Add like terms and solve for x:

17x - 23 = 11x + 13

6x - 23 = 13

6x = 36

x = 6

So, x = 6

Step-by-step explanation:

14) Bill is looking to work at two different car dealerships. The Subaru dealership is going
to offer him a monthly pay of $1200 plus 4.5% of his total sales. His monthly sales can
be represented by x. The BMW dealership will give him a flat pay of $1600 monthly.
Use an inequality to show when it would be better for him to choose to work at Subaru
then BMW. Solve your inequality and determine the amount of sales he needs to make
in order for it to be a better choice to work at Subaru.

Answers

Answer:

1) $1,200 + x × 4.5/100 > $1,600

2) Bill has to make more than $8,888.[tex]\bar 8[/tex], in total sales monthly for it to be a better choice to work at Subaru

Step-by-step explanation:

1) The given parameters are;

The amount of monthly pay the Subaru dealership is offering = $1,200

The percentage of his total sales, x, Subaru dealership is offering = 4.5%

The flat monthly pay the BMW dealership is offering = $1,600

Therefore, the inequality to show when it would be better for him to choose to work for Subaru is given as follows;

$1,200 + x × 4.5/100 > $1,600

2) The solution of the above inequality is given as follows;

$1,200 + x × 4.5/100 > $1,600

x × 4.5/100 > $1,600 - $1,200

x × 4.5/100 > $400

x > $400 × 100/4.5  = $8,888.[tex]\bar 8[/tex]

Therefore, in order to make it better to work at Subaru, Bill has to sell more than $8,888.[tex]\bar 8[/tex] worth of cars every month.

Step-by-step explanation:

How to calculate unit price of something?

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.

Thus, unit price of something is price of 1 thing.

Thus, suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.

It is given that Vera went to the local salon to get a haircut. The cost was $24. Vera tipped the hair stylist 18%.

SO,

18% = 18/100 = 0.18

18% of 24 = 0.18*24

= 4.32

The tip is $4.32

Adding this tip amount onto the original bill leads to;

4.32+24 = 28.32

Hence, the total cost of the haircut including the tip will be $28.32.
