It would be: 360- (101+133+76)

360-310 = 50 degree

3(s-5)/4 -3 = 4s- (s-3)/2<br>pls answer fast

Jobisdone [24]

Answer:

$s = \frac{9± \sqrt{ - 39} }{4}$

Step-by-step explanation:

$\frac{3(s - 5)}{4 - 3} = \frac{4s \times (s - 3)}{2}$

➡️ $\frac{3(s - 5)}{1} = 2s \times (s - 3)$

➡️ $3s - 15 = 2 {s}^{2} - 6s$

➡️ $3s - 15 - 2 {s}^{2} + 6s = 0$

➡️ $9s - 15 - 2 {s}^{2} = 0$

➡️ $- 2 {s}^{2} + 9s - 15 = 0$

➡️ $2 {s}^{2} - 9s + 15 = 0$

➡️ $s = \frac{ - ( - 9)± \sqrt{( - 9 {)}^{2} - 4 \times 2 \times 15} }{2 \times 2}$

➡️ $s = \frac{9± \sqrt{81 - 120} }{4}$

➡️ $s = \frac{9± \sqrt{ - 39} }{4}$

➡️ $s∉ℝ$

For f (x) = 4 x +1 and g(x) = x^2- 5, find (g/f)(x)

Lady bird [3.3K]

Answer:

The answer is: $\frac{x^2-5}{4x+1}$

Step-by-step explanation:

We are given: $f(x)=4x+1$ and $g(x) = x^2-5$

We need to find $(g/f)(x)$ .

Simply divide $g(x)$ and $f(x)\\$ .

Which equates to:

$(g/f)(x)= \frac{g(x)}{f(x)} =\frac{x^2-5}{4x+1}$

This cannot be simplified further, so it is the answer.

A family swimming pool holds 61 m3 of water. It loses 0.27m3 of water to evaporation each day. This situation can be represented

Bezzdna [24]

Answer:

The answer to your question is: when x = 100 days, y = 34 m³

Step-by-step explanation:

Data

Volumen = 61 m³

Loses 0.27 m³ each day

Equation y + 0.27x = 61

when x = 100, y = ?

Process, just substitute x in the equation and solve it for y

y + 0.27(100) = 61

y + 27 = 61

y = 61 - 27

y = 34 m³

It means that after ten days, the swimming pool will only have 34 m³, because 27 m³ will have evaporated.

Angle ABC is congruent to

Vesna [10]

Answer:

In words, if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the triangles are congruent. If in triangles ABC and DEF, angle A = angle D = right angle, AB = DE (leg), and BC = EF (hypotenuse), then triangle ABC is congruent to triangle DEF.
