Answer:

Step-by-step explanation:

If we make an equation for this we get:

(36 3/4 + 36 3/8 + 37 1/2 + z) / 4 = 36 5/8

Then we multiply to only get the parentheses:

36 3/4 + 36 3/8 + 37 1/2 + z = 146.5

Then we combine like terms which makes:

110.625 + z = 146.5

Then we subtract on both sides which makes:

z = 35.875

Make it into a fraction it makes: 35 7/8

Maria practice the piano 5/6 of an hour everyday. How many hours does she practice in 4 days

S_A_V [24]

Answer:
10/3 hours

Explanation:
If Maria practices 5/6 hours a day, then she practices (5/6)(4) hours in 4 days.

(5/6)(4)=20/6

20/6 can be simplified to 10/3 hours.

I hope this helps!

The equation of the graphed line in point-slope form is?, and it’s equation in slope-intercept form is?

tester [92]

ANSWER

Point-slope form:

$y - 3 = -\frac{3}{5} (x + 2)$

Slope-intercept form:

$y= -\frac{3}{5} x + \frac{9}{5}$

EXPLANATION

The graphed line passes through

$(-2,3) \: \: and \: \: (3,0)$

The slope of this line is determined using

$m = \frac{y_2-y_1}{x_2-x_1}$

We substitute the points to get;

$m = \frac{0 - 3}{3 - - 2}$

$m = -\frac{3}{5}$

The point-slope formula is:

$y-y_1 = m(x - x_1)$

Substitute the first point and slope to get:

$y - 3 = -\frac{3}{5} (x - - 2)$

$y - 3 = -\frac{3}{5} (x + 2)$

To find the slope-intercept form, we expand to get:

$y= -\frac{3}{5} x - \frac{6}{5} + 3$

$y= -\frac{3}{5} x + \frac{9}{5}$

how do you find the length of the hypotenuse when you have only the length of the altitude of the hypotensuse and a length of a

mrs_skeptik [129]

Answer:

By using The Pythagorean Theorem:

$/Hypotenuse/^{2} = /Length of altitude/^{2} + /Length of leg/^{2} \$

/Hypotenuse/ = $\sqrt\ /Length of altitude/^{2} + /Length of leg/^{2} \}$

Step-by-step explanation:

The Pythagorean theorem states that: Given a Right-angled triangle, the square of the hypotenuse equals the sum of squares of the other two sides ( Here, being the length of the altitude and length of leg). That is,

$/Hypotenuse/^{2} = /Length of altitude/^{2} + /Length of leg/^{2} \$ and hence,

/Hypotenuse/ = $\sqrt\ /Length of altitude/^{2} + /Length of leg/^{2} \}$

For example, If the length of the altitude is 4m and the length of leg is 3m. Using The Pythagorean theorem, the length of the hypotenuse will be

$/Hypotenuse/^{2} = /Length of altitude/^{2} + /Length of leg/^{2} \\\/Hypotenuse/ = \sqrt{/Length of altitude/^{2} + /Length of leg/^{2}} \\/Hypotenuse/ = \sqrt{4^{2} + 3^{2} }$

$/Hypotenuse/ = \sqrt{16+9} \\/Hypotenuse/ = \sqrt{25} \\/Hypotenuse/ = 5m$

The length of the hypotenuse for the given example will be 5m.

This is how to find the length of an hypotenuse.
