An angle is 15 degrees less than twice its complement. find the angles

1 answer:

7 0

The measure of an angle = 2 * the compliment of the angle - 15
Angle = 2 * (180 - angle) - 15
x = 2 * 180 - 2 * x - 15
x = 345 - 2x
3x = 345

x = 115 degrees.

if each small tile cost 15 pesos & each big tile should emmanuel use to economize in tilin his floor? explain why

Olenka [21]

It's not possible to answer this question without the other information in the middle,
which you skipped as you copied the question. That information tells us the size
of the big tiles, the size of the small tiles, and the size of the room. That's how we
figure out how many tiles he needs, and once we know that, we can figure out how
much they cost. (You also skipped the cost of the big tiles. We'll need that too.)

Given that f(x) = 5x - 10 and g(x) = x + 3, find f(g(-1)).

musickatia [10]

$\bf \begin{cases} f(x) = 5x-10\\ g(x) = x + 3 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ g(-1)=(-1)+3\implies \boxed{g(-1) = 2} \\\\\\ f(~~g(-1)~~)\implies f\left( \boxed{2} \right) = 5(2)-10\implies \stackrel{f(~g(-1)~)}{f(2)}=0$

Which of the following is the product

choli [55]

Answer:

$\text{\bf{A.}}\quad\dfrac{3x^2}{x^2-6x-7}$

Step-by-step explanation:

As with multiplying any rational expressions, the numerator of the result is the product of the numerators, and the denominator of the result is the product of the denominators.

$\dfrac{3x}{x+1}\cdot\dfrac{x}{x-7}=\dfrac{(3x)(x)}{(x+1)(x-7)}=\dfrac{3x^2}{x^2-6x-7}$

_____

The denominator product is found using the distributive property. Each of the terms of one factor is multiplied by the other factor.

$(x+1)(x-7)=x(x-7)+1(x-7)\\\\=x^2-7x+1x-7=x^2-6x-7$

Kenny bought a 50-pound bag of chicken feed for $29.98 and a 25-pound bag for $15.49. Can you use proportional reasoning to find

Alla [95]

$\frac{50 \: lbs}{29.98} = \frac{1 \: lb}{0.596}$
$\frac{ 25 \: lbs}{15.49} = \frac{1 \: lb}{0.6196}$
$\frac{1 \: lb}{0.596} < \frac{1 \: lb}{0.6196}$
Since the proportions are different, it's best to say that to determine the price of a 40-pound bag, proportional reasoning is no where to be found so no, proportional reasoning cannot be used to find the price of a 40-pound bag!
