Answer:

B. One

Step-by-step explanation:

Since the two angles are already given, the value of the third angle is already fixed. The third angle can be found by the sum of both angles subtracted from 180. Since 2 angles and lengths are already given, there can only be 1 triangle.

Hope this helps!

If not, I am sorry.

The doctor recommended that Mike increase the number of calories he burns working out from 1,500 to 1,800. By what percent did t

Viefleur [7K]

Answer: The number of calories increased by 20%.

Step-by-step explanation:

Given : The doctor recommended that Mike increase the number of calories he burns working out from 1,500 to 1,800.

Previous number of calories he used to burn = 1,500

Increase in calories = 1800-1500=300

Now , the percent increase in calories = $\dfrac{\text{Increase in calories}}{\text{previous calories}}\times100$

$=\dfrac{300}{1500}\times100=20\%$

Hence , the number of calories increased by 20%.

Write an equation in point-slope for, for the line through the given spot (4, -6); m = 3/5

oee [108]

The point-slope form:

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

We have the point (4, -6) and the slope m = 3/5. Substitute:

$y-(-6)=\dfrac{3}{5}(x-4)\\\\\boxed{y+6=\dfrac{3}{5}(x-4)}$

An amount of $180 is shared among three people in the ratio x: y: z.

sammy [17]

Answer:

$110 and $30

Step-by-step explanation:

To solve this, we need to know the total share which is,

$4 + 11 + 3 = 18$

Then, you need to know the fraction of the share over the total, such that

$x = \frac{4}{18}$

$y = \frac{11}{18}$

$z = \frac{3}{18}$

So if to find how much that'll be of the $180 for the largest and smallest share,

Largest:

$\frac{11}{18} \times 180 = 110$

Smallest:

$\frac{3}{18} \times 180 = 30$
