Answer:

a) The ladder reach 19.32 foot up the house

b) The bottom of the ladder is 5.18 foot from the house

Step-by-step explanation:

An illustrative diagram of the scenario is attached below.

From the diagram, we have a right angle triangle with the length of the ladder being the hypotenuse. The opposite indicates how far up the house the ladder reach and the adjacent indicates the distance of the bottom of ladder from the house.

a) To determine how far up the house the ladder reach, that is the opposite.   Let the opposite be y

From the formula

Sinθ = Opposite / Hypotenuse

Where θ is the angle subtended

Here θ = 75°

Hypotenuse = 20 foot

∴ sin75° = y / 20

y = 20 × sin75°

y = 20 × 0.9659

y = 19.32 foot

Hence, the ladder reach 19.32 foot up the house.

b) To determine how far from the house the bottom of the ladder is, that is the adjacent. Let the adjacent be x

From the formula

Cosθ = Adjacent / Hypotenuse

Where θ is the angle subtended

Then,

cos75° = x / 20

∴ x = 20 × cos75°

x = 20 × 0.2588

x = 5.18 foot

Hence, the bottom of the ladder is 5.18 foot from the house.

Answer:

46 of the total vehicles are minivans

Step-by-step explanation:

Let the number of minivans be x

and the number of other types of vehicles be y

From the question,

Carla noticed that for every 2 minivans, there were 5 other types of vehicles.

This means the ratio of minivans to other types of vehicles is 2:5.

Therefore,

x:y = 2:5

We can then write that

x/y = 2/5

∴ 5x = 2y ...... (1)

Also from the question,

There are 161 total vehicles in the parking lot

That is

x + y = 161 ...... (2)

From equation (2), we can write that

y = 161 - x

Put this into equation (1)

5x = 2y

Then

5x = 2(161-x)

5x = 322 -2x

5x+2x = 322

7x = 322

x = 322/7

x = 46

Since x represent the number of minivans

Hence, 46 of the total vehicles are minivans.

Answer:

40 + 2x = 180

Step-by-step explanation:

Since it is an isosceles triangle, there will be 2 angle x's and all angles will equal to 180 degrees, therefore the equation that will help with finding the measurement of angle x is 40 + 2x = 180.

Answer:

  (-1, 0)

Step-by-step explanation:

We want the point (4x, f(4x)) to match (-4, 0). We already know that f(-4) = 0, so we want 4x = -4.

  4x = -4

  x = -1 . . . . divide by 4

The desired point is (-1, 0).

Answer:

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

[tex]\frac{y-1}{2}[/tex] = x

Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

b) The perpendicular bisector of AB.

Answer: There are 25 crates and 15 boxes in the truck when it is full.

Step-by-step explanation:

Let c= Number of crates , b= Number of boxes.

As per given,

[tex]c+b = 40[/tex]     (i)

[tex]3c=5b\\\\\Rightarow\ c=\dfrac{5b}{3}[/tex]        (ii)

Put value of c from (ii) in (i)

[tex]\dfrac{5b}{3}+b = 40\\\\\Rightarrow\ \dfrac{5b+3b}{3}=40\\\\\Rightarrow\ \dfrac{8b}{3}=40\\\\\Rightarrow\ 8b=3\times40\\\\\Rightarrow\ 8b=120\\\\\Rightarrow\ b=\dfrac{120}{8}=15[/tex]

put value of b in (ii),

[tex]c=\dfrac{5\times15}{3}=5\times5=25[/tex]

Hence, there are 25 crates and 15 boxes in the truck when it is full.

25 boxes 15 crates

We would get this solution by adding up the two sides comparing the ratios, hence: we get room for 3 crates for every 5 boxes that we can hold in the truck.

A ratio is an ordered pair of numbers a and b, written a:b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. hence, if there is 3 crates and 5 boxes you could write the ratio as: 3 : 5 (for every 3 crates there are 5 boxes) 3 / 5 are boys and 5 / 3 are crates.

Answer:

B. y=1/4x-2

Step-by-step explanation:

The -2 in this equation represents the y value. The graph passes through -2 on the y axis, so you automatically cancel out the rest of the answers.

Option B is correct, y=1/4x - 2 is the function which  best represented by the given graph.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The line is passing through the points (0, -2) and (4, -1)

Let us find the slope m.

m = -1-(-2)/4

=1/4

So slope is 1/4

Now let us find the y intercept

-2=1/4(0)+b

-2=b

So equation will be y=1/4x-2

Hence, Option B is correct, y=1/4x - 2 is the function which  best represented by the given graph.

4r4r4r4r4r4r4r4r344r3r3

r44r3rStep-by-step explanation:

The ratio which is equivalent to 33:39 is 11:13

An equaivalent ratio are fraction whose value are equal and are integral multiples of each other.

For example 1:2 = 2:4

Since 1:2 = 1 × 2 : 2 × 2 = 2 : 4

Also, 2:4 = 2 ÷ 2: 4 ÷ 2 = 1 : 2

We see that 1:2 and 2:4 are equivalent since we multiply 1:2 by 2 to get 2:4 or divide 2:4 by 2 to get 1:2.

So, to find the ratio equivalent to 33:39, we write 33:39 in its simplest terms.

So, 33:39 = 11 × 3 : 13 × 3

= 11 : 13

So, the ratio which is equivalent to 33:39 is 11:13

Complete question is;

An ordinary deck of playing cards has 52 cards. There are four suits

-spades, hearts, diamonds, and clubs

-with 13 cards in each suit.

Spades and clubs are black; hearts and diamonds are red. One of these cards is selected at random. Let A denote the event that a red card is chosen.

Find the probability that a red card is chosen, and express your answer in probability notation.

Answer:

P(A) = 0.5

Step-by-step explanation:

We are told that the ordinary deck of playing cards has 52 cards.

Now, there are four suits

-spades, hearts, diamonds, and clubs

-with 13 cards in each suit.

Now, in a standard set of playing cards, there are 13 black spades and 13 black clubs as well as 13 red hearts and 13 red diamonds

Thus;

Number of red cards = 13 + 13

Thus;

Number of red cards = 26

Since, A denotes the event that red card is chosen.

This means that probability of choosing a red card is;

P(A) = number of red cards/total number in a deck of cards

P(A) = 26/52

P(A) = 0.5

Answer:

70%

Step-by-step explanation:

Given that:

Initial water level in the tank at noon = 10 cm

After several hours, water level = 3 cm

To find the percentage change in the water in the tank, we can use the following formula:

[tex]Percentage\ Change = \dfrac{Final\ Value - Initial\ Value }{Initial\ Value}\times 100[/tex]

Here, Final Value = 3 cm

Initial Value = 10 cm

Putting the values in the formula:

[tex]Percentage\ Change = \dfrac{3 - 10 }{10}\times 100\\\Rightarrow Percentage\ Change = -70\%[/tex]

Here, negative value, means there is a decrease in the final value from the initial value.

Therefore, the answer is 70% decrease.

Answer:

96 calories per cup

384 calories in 4 cups

Step-by-step explanation:

In this scenario, we can use the rule of three to calculate the number of calories in a single cup like so...

72 calories   <==========>   [tex]\frac{3}{4} cup[/tex]  or 0.75 cup

 x  calories   <==========>  1 cup

(1 * 72) / 0.75 = 96 calories

Now we see that there are a total of 96 calories per cup of cereal. In order to find the total amount of calories in 4 cups of cereal, we simply need to multiply the number of calories per cup by 4, like so...

96 * 4 = 384 calories

There are a total of 384 calories in 4 cups of cereal.
