A 20 foot ladder is placed against a wall at a 75 degree angle with the ground. The wall is perpendicular to the ground.

PART A: How high on the wall, in feet, will the ladder reach? Round your answer to the nearest tenth. Show your work.

PART B: What is the distance, in feet, from the wall to the base of the ladder? Show your work.

Answers

Answer 1

Answer:

Part A)

Height = 19.3 feet

Part B)

Distance = 5.2 feet

Step-by-step explanation:

Part A)

Let ladder reaches upto the h height of the wall.

[tex] \therefore \sin \theta =\frac{h}{length\: of\: the \:ladder} [/tex]

[tex] \therefore \sin 75\degree =\frac{h}{20} [/tex]

[tex] \therefore 0.9659258263 =\frac{h}{20} [/tex]

[tex] \therefore 0.9659258263\times 20 = h [/tex]

[tex] \therefore 19.3185165 \: ft= h [/tex]

[tex] \therefore h = 19.3 \: ft= h [/tex]

Part B)

Let the distance from the wall to the base of the ladder be x feet.

[tex] \therefore \cos \theta =\frac{x}{length\: of\: the \:ladder} [/tex]

[tex] \therefore \cos 75\degree =\frac{x}{20} [/tex]

[tex] \therefore 0.2588190451 =\frac{x}{20} [/tex]

[tex] \therefore 0.2588190451\times 20 = x [/tex]

[tex] \therefore 5.1763809 \: ft= x [/tex]

[tex] \therefore x = 5.2 \: ft [/tex]

how do i find an equation for a line with an x-intercept of 4 and a y-intercept of -2

Answers

Answer:

The equation of a line is y = ax + b, where a is the slope and b is the y-intercept.  

Since we have the y-intercept, all we need to do is find the slope. To find the slope, you need 2 coordinates.

The y-intercept is where the line crosses the y axis, so it is where x is 0. Since the y intercept is -2, that means the first coordinate is (0, -2)

The x-intercept is where the line crosses the x axis, so it is where y is 0. Since the x intercept is 4, that means the second coordinate is (4, 0)

Since we already have the y-intercept, all we do is put the slope in the equation: y = 1/2x - 2.

Arjun's piggy bank contains two kinds of coins and two kinds of bills. there are twice as many $1 bills like $5 bills. the number of quarters is 1 more than three times the number of $5 bills. and the number of dimes is 7 less than the number of quarters. how many of each type of bill and coin does Arjun have if the total is $39.90?

Answers

Answer:

$5 bills x 5, $1 bills x 10, quarters x 16, dimes x 9

Step-by-step explanation:

$5 bills = x, total = 5x$1 bills = 2x, total = xQuarters = 3x + 1, total = 0.25(3x + 1)Dimes = 3x + 1 - 7= 3x - 6, total = 0.1(3x - 6)

Equation below as the sum, solve for x:

5x + 2x + 0.25(3x + 1) + 0.1(3x - 6) = 39.97x + 0.75x + 0.25 + 0.3x - 0.6 = 39.98.05x  - 0.35 = 39.98.05x = 40.25x = 40.25/8.05x = 5

Number of each bill and coin:

$5 bills = 5$1 bills = 2*5 = 10Quarters = 3*5 + 1 = 16Dimes = 3*5 - 6 = 9

jan has a 12-ounce milkshake.Four ounces in the milkshake are vanilla,and the rest is chocolate.What are two equivalent fractions that represent the fraction of the milkshake that is vanilla

Answers

Answer:

In this item, we are given that out of 12 ounces of ingredients comprising the milkshake, there are 4 ounces vanilla. Expressing this into fraction will give us an answer of 4/12. This fraction can be one of the answers. Since we are asked for two fractions, we can simplify 4/12 such that we get an equivalent fraction that is equal to 2/6. Hence, the answers to this question are 4/12 and 2/6.
