F-27=19

F= 19+27

F=46

I hope it is helpful have a nice day

Answer:

answer is 46

Step-by-step explanation:

Solution for f-27=19 equation:

Simplifying

f + -27 = 19

Reorder the terms:

-27 + f = 19

Solving

-27 + f = 19

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Add '27' to each side of the equation.

-27 + 27 + f = 19 + 27

Combine like terms: -27 + 27 = 0

0 + f = 19 + 27

f = 19 + 27

Combine like terms: 19 + 27 = 46

f = 46

Simplifying

f = 46

Melany takes her little sister to the zoo. They go see their favorite animal, the giraffe. At the gift shop, Melany buys a stuffed giraffe for her little sister that has a scale on 4 in : 3 ft. If the real giraffe is 18 feet tall, how tall is the stuffed giraffe, in inches?

Answers

Let us set up a proportion.

4/3 = 18/t

Let t = height of giraffe (in inches)

We also have to change units to make our math work easier.

There are 12 inches in one foot.

So, 3 feet = 36 inches and 18 feet = 216 inches.

Our new proportion set up is:

4/t = 36/216

36t = 4(216)

36t = 864

t = 864/36

t = 24

The toy giraffe is 24 inches tall.

Rotate (-7,5) 90 degrees clockwise about the origin and then translate the new point left 6

Answers

Answer:

[tex]P" = (-1,7)[/tex]

Step-by-step explanation:

Given

[tex]Point - (-7,5)[/tex]

90 degrees clockwise rotation

6 points left translation

Required

The new point

Apply the first transformation

90 degrees clockwise transformation

When a point P (x,y) is rotated in the clockwise direction by 90 degrees, the new point is: P' (y, -x)

So:

[tex]P = (-7,5)[/tex] becomes

[tex]P' = (5,7)[/tex]

Apply the second transformation

6 points left translation

To do this, we simply subtract 6 from the x coordinate

[tex]P' = (5,7)[/tex] becomes

[tex]P" = (5-6,7)[/tex]

[tex]P" = (-1,7)[/tex]

a. [tex]\sec \beta \cot \beta[/tex]
b. [tex]\tan \beta[/tex]
c. [tex]\cot \beta \tan \beta[/tex]
d. [tex]\tan \beta \csc \beta \sec \beta[/tex]

Answers

[tex]\large\boxed{Answer:}[/tex]

We will use trigonometric identities to solve this. I will use θ (theta) for the angle.

First of all, we know that cotθ = 1/tanθ. This is a trigonometric identity.

We can replace cotθ in the expression with 1/tanθ.

[tex]sin\theta tan\theta sec\theta \frac{1}{tan\theta}[/tex]

Simplify: 1/tanθ * tanθ = tanθ/tanθ = 1

So now, we have:

[tex]sin\theta sec\theta[/tex]

Next, we also know that secθ = 1/cosθ. This is another trigonometric identity.

We can replace secθ with 1/cosθ in our expression.

[tex]sin\theta \frac{1}{cos\theta}[/tex]

Simplify:

[tex]\frac{sin\theta}{cos\theta}[/tex]

Our third trigonometric identity that we will use is tanθ = sinθ/cosθ.

We can replace sinθ/cosθ with tanθ.

Now we have as our final answer:

[tex]\large\boxed{b.\ tan\theta}[/tex]

Hope this helps!

Answers

Answer:

we know that

the length of Q is 25% more than the length of p

so

length Q=1.25*40--------> 50 cm

the area of Q is 10% less than the area of p

Area Q=50*y

Area P=40*x

so

50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18

the answer

the ratio x:y is 25:18
