Find the area of the isosceles triangle. please help thanks

Answers

Answer:

1080 m^2 Don't submit m^2 in your answer.

Step-by-step explanation:

Givens

The catch is to find h

To do that, use a^2 + b^2 = c^2

a b and c are in the same 1/2 triangle.

a = 48/2 = 24 m

b = h = ?

c = 51 meters

Solution

a^2 + b^2 = 51^2                      Substitute for b^2 = h^2

24^2 + h^2 = 51^2                   Expand 24^2 and 51^2

576 + h^2 = 2601                    Subtract 576 from both sides

h^2 = 2601 - 576

h^2 = 2025                              Take the square root of both sides

h = 45

Area

Area = 1/2 b * h

Area = 1/2 48 * 45

Area = 1080

Remark

Notice that to find h you only use 1/2 of 48 because that is the base of the right triangle.

To find the area, you need to use all of 48 because 48 is the full length of the base.

Step-by-step explanation:

The Volume of the box will be 8000 in.³

What is volume ?

Volume is a three dimensional space occupy by the body of particular shape such as here :

It should be noted that a box has six sides that are equal. In this case, we've been given the side of one of the lengths to be 20 inches.

The volume of a cube is :

V = a³

Therefore, the Volume of the box will be :

V = 20³

V = 8000 in.³

Therefore, the Volume of the box will be 8000 in.³

Hi there!

[tex]\large\boxed{x = \frac{24z}{(18 + yz)} }[/tex]

We can begin solving by creating a common denominator:

x · 3 · z = 3xz. This is the denominator that all of the numerators must have in order to work with the fractions.

Multiply each numerator by the missing parts of the common denominator:

[tex]\frac{8 * 3 * z}{3xz} - \frac{y * x * z}{3xz} = \frac{6 * 3 * x}{3xz}[/tex]

Simplify:

[tex]\frac{24z}{3xz} - \frac{yxz}{3xz} = \frac{18x}{3xz}[/tex]

Move all the fractions involving x in the numerator to the right-hand side of the equation:

[tex]\frac{24z}{3xz} = \frac{18x}{3xz} + \frac{yxz}{3xz}[/tex]

Combine fractions:

[tex]\frac{24z}{3xz} = \frac{18x + yxz}{3xz}[/tex]

Multiply both sides by 3xz:

[tex]24z = 18x + yxz[/tex]

Factor out "x" from the terms on the right-hand side:

[tex]24z = x(18 + yz)[/tex]

Divide both sides by (18 + yz)

[tex]\frac{24z}{(18 + yz)} = x[/tex]

When exercising, the maximum heart rate (r ) in beats per minute is modeled by the equation shown in the box, where (a ) represents the age of the person in years. r = 220 - a If Sanchez is 34 years old, what is his maximum heart rate?

Answers

Answer:

186 beats per minute

Step-by-step explanation:

The maximum heart rate (r ) in beats per minute is modeled by the equation :

r = 220 - a ...(1)

Where

a is age of the person in years

If Sanchez age is, a = 34 years

Put a = 34 in equation (1)

r = 220 - 34

= 186 beats per minute

Hence, the maximum heart rate is 186 beats per minute.

Answers

first find the slope (which is -2/3)

then plug into point-slope formula using the coordinates. if you dont remember point-slope is “y-y1 = m (x-x1) where y1 being the y of the coordinate while x1 being the x of the coordinate and m being the slope.

plug it in to get “y+5 = -2/3 (x-4)

x – 7y = –11
5x + 2y = -18

Answers

Answer:

hope this help you

Step-by-step explanation:

Simplifying

X + -7y = -11

Solving

X + -7y = -11  

Solving for variable 'X'.

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

Add '7y' to each side of the equation.

X + -7y + 7y = -11 + 7y

Combine like terms: -7y + 7y = 0

X = -11 + 7y

Simplifying

X = -11 + 7y

------------------------------------------------------------------------------------------------------------

Solving

5x + 2y = -18

Solving for variable 'x'.

Add '-2y' to each side of the equation.

5x + 2y + -2y = -18 + -2y

Combine like terms: 2y + -2y = 0

5x = -18 + -2y

Divide each side by '5'.

x = -3.6 + -0.4y

Simplifying

x = -3.6 + -0.4y
