Answer:

There are 9 geese and 18 horses.

Step-by-step explanation:

Step 1: Make equations.

g ... number of geese

h ... number of horses

First equation: There are 27 animals in the barn.

g + h = 27

Second equation: There are 90 legs in all.

We know geese have two legs and horses 4.

2g + 4h = 90

Step 2: Solve the system of equations.

g + h = 27 (first equation)

2g + 4h = 90 (second equation)

Let's express g in terms of h in first equation.

g + h = 27

g = 27 - h

Now let's substitute g in second equation with g in first equation.

2g + 4h = 90

2(27 - h) + 4h = 90

And solve for h.

54 - 2h + 4h = 90

54 + 2h = 90

2h = 90 - 54

2h = 36

h = 18

Let's substitute the value of h back to first equation to get g.

g = 27 - h

g = 27 - 18

g = 9

its true

they are both already right triangles so if both have acute angles that are congruent then the right triangles are similar

if one of the acute angles of a right triangle is congruent to an acute angle of another right triangle then by angle angle Similarity the triangles are similar

Answer:

the answer for all of this question should be

C=( -10, -2)

D=(0, -2)

E=(0,8)

F=(-10,8)

so remember the quadruants and remember if the x is negative or positive and if the y is either negative or positive so hopefully those are the correct one and if not tell me whats wrong so i can edit it to make it better.

Answer:

A = 12

Step-by-step explanation:

We can define ratio a to b as 12:3. If we are finding the value of A when B is 3, we go to the ratio. The ratio says that when B is 3, A is 12. Therefore, A is 12.

Answer:

A = 12

Explanation:

Given:

A ∝ B

set "k" constant

A = k(B)

Find "k"

12 = k(3)

k = 4

Then find A when B = 3

A = k(B)

insert values found

A = 4(3)

A = 12

Answer:

Angle 1 = 63.3

Angle 2 = 37.3

Angle 3 = 63.3

Angle 4 = 142.7

Step-by-step explanation:

When a line intersects two parallel lines the interior angles are equal. So angle 2 = 37.3

Angle 3 = 180 - (79.4 + 37.3) = 63.3 since the sum of the angles on a straight line must be 180

Ange 1 = Angle 3 = 63.3

Angle 4 = 180-37.3 = 142.7

See below for answers and explanations

Step-by-step explanation:

If we check x=5:

[tex]f(5)=-(5)^3+7(5)^2-7(5)-15\\f(5)=-125+7(25)-35-15\\f(5)=-125+175-50\\f(5)=50-50\\f(5)=0[/tex]

So [tex]x=5[/tex] is indeed a zero

If we check x=3:

[tex]f(3)=-(3)^3+7(3)^2-7(3)-15\\f(3)=-27+7(9)-21-15\\f(3)=-27+63-36\\f(3)=36-36\\f(3)=0[/tex]

So [tex]x=3[/tex] is also indeed a zero

If we check x=-1:

[tex]f(-1)=-(-1)^3+7(-1)^2-7(-1)-15\\f(-1)=1+7+7-15\\f(-1)=8+7-15\\f(-1)=15-15\\f(-1)=0[/tex]

So [tex]x=-1[/tex] is also indeed a zero

Answer:

[tex]\sf \tan(C)=\dfrac{3}{4}[/tex]

Step-by-step explanation:

First, find the missing side length (DE) by using Pythagoras' Theorem:

a² + b² = c²  

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

⇒ 36² + DE² = 45²  

⇒ DE² = 45² - 36²

⇒ DE² = 729

The approximated value of π using the integer digits 1 2 3 4 5 6 7 8 is is 3.142857

The integers are given as:

1 2 3 4 5 6 7 8

The value of π is:

π = 22/7

Evaluate the quotient

π = 3.14285714286

From the question, the digits 1 to 8 have to appear just once.

So, we approximate the number up to the point where any of the given digits has more than one occurrence.

So, we have:

π = 3.142857

Hence, the approximated value of π is 3.142857

The equation that can be determined by the coordinates for point B will be 25 = (x - 6)² + (y - 5)².

The study of geometry using points in space is known as coordinate geometry. This may be used to discover the length between the endpoints, the dividing line's m:n ratio, the line's mid-point, and so on.

Segment AB has point A located at (6, 5). If the distance from A to B is 5 units.

Then the equation that can be determined by the coordinates for point B will be

[tex]\rm 5 = \sqrt{(x-6)^2 +(y-5)^2}[/tex]

This can be written as

25 = (x - 6)² + (y - 5)²
