Answer:

$\boxed{-\frac{7}{12} }$

Step-by-step explanation:

$-1\frac{1}{3} +\frac{3}{4}$

→ Make both denominators the same

$-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}$

→ Convert mixed number into improper fraction

$-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}$

→ Do the -16 + 9 and leave 12 as the denominator

$-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}=-\frac{7}{12}$

The Frostburg-Truth bus travels on a straight road from Frostburg Mall to Sojourner Truth Park. The mall is 3 miles west and 4 m

geniusboy [140]

We take the distance from points which indicates the location of the park and the mall.

For distance through north and east, we have positive values and negative for west and south.

Mall: (-3, -4)
Park: (3, 5)

The distance is calculate through the equation,
d = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)

Substituting,
d = sqrt ((-4 - 5)² + (-3 - 3)²
d = sqrt 117 = 10.82
Thus, the distance between the mall and the park is approximately 10.82 miles.

Solve 5n^2=5 with the quadratic formula

Yanka [14]

Answer:

n = 1

Step-by-step explanation:

First, rearrange the equation to standard form 0 = ax² + bx + c, when everything equals 0.

5n² = 5

5n² - 5 = 0

State the variables a, b and c.

a = 5; b = 0; c = -5

Substitute a, b, and c into the quadratic formula.

$n = \frac{-b ±\sqrt{b^{2}-4ac} }{2a}$

$n = \frac{-0 ±\sqrt{0^{2}-4(5)(-5)} }{2(5)}$ Substitute

$n = \frac{\sqrt{100} }{10}$ Simplify inside the √ and bottom

$n = \frac{10}{10}$ Simplify the top

$n = 1$ Final answer

Therefore the solution is n = 1.

The quadratic formula usually is written with x, but it can be solved with any variable in standard form.

Aleks [24]

Answer:

$6x^2+5x-6=(3x-2)(2x+3)$

Step-by-step explanation:

Given expression:

$6x^2+5x-6$

To factor a quadratic in the form $ax^2+bx+c$ , first find two numbers that multiply to $ac$ and sum to $b$ :

$\implies ac=6 \cdot -6=-36$

$\implies b=5$

Two numbers that multiply to -36 and sum to 5 are: 9 and -4

Rewrite b as the sum of these two numbers:

$\implies 6x^2+9x-4x-6$

Factorize the first two terms and the last two terms separately:

$\implies 3x(2x+3)-2(2x+3)$

Factor out the common term (2x + 3):

$\implies (3x-2)(2x+3)$

Therefore:

$6x^2+5x-6=(3x-2)(2x+3)$

6 The radius of the base of a cylinder is 39 in. and its height is 33 in.. Find the surface area of the cylinder in terms of s.

Delvig [45]

Answer:

17650 in².

Step-by-step explanation:

Given that the base of cylinder is 39 inch and it's height is 33inches . We need to find the surface area of the cylinder . So we know the TSA of cylinder as ,

$\bf\implies TSA_{(cylinder)}= 2\pi r ( r + h ) \\\\\bf\implies TSA_{(cylinder)}= 2\pi 39 ( 39 + 33) in.^2\\\\\bf\implies TSA_{(cylinder)}= 2\times \dfrac{22}{7}\times 39 \times 72 \\\\\sf:\implies \boxed{\red{\bf TSA_{(cylinder)}= 17650 in^2}}$
