Answer:

Step-by-step explanation:

remove the 0 from the equation(it doesn't change anything because it's 0) then add the numbers , 17+12=29 then you want to move the constant to the right so x=32-29 .

32-29=3

Answer:

x = 25 and <A = 148 degrees

Step-by-step explanation:

Basically it's asking you to find the value of x for both of those equations, x must be the same for both

6x - 2 = 4x + 48

If c=25 and B=75 degrees, find a. Round to the nearest tenth.

worty [1.4K]

Answer:

a=6.9

Step-by-step explanation:

Since you know that C is a right angle, you can use the Law of Sines to find a. The first step is to find the size of the angle A, which is 180-74-90=16. Now, you set up a ratio that involves 3 knowns and one unknown to get $\frac{\sin(90^\circ)}{25} = \frac{\sin(16^\circ)}{a}$ , which after cross multiplying yields $a=\sin(16^\circ)\cdot25\approx 6.9$ . PM me if you have any questions?

If a firm finds that increases in output lead to increases in long-run average total cost, then it must be experiencing ________

Luba_88 [7]

Answer:

The correct option is;

C diseconomies of scale; coordination problems

Step-by-step explanation:

Dis-economies of scale is in effect where the average cost of production of firm increases as it increases its inputs towards producing more. That is as the production rate increases, the unit cost of production also increases

Increase in the mean cost of production as the production rate increases is an indication of diminishing returns to increasing scale of production

Dis-economies of scale can be caused by Coordination problems

Difficulties in Co-ordination and monitoring . Where there is growth, the monitoring and coordination requirements becomes more complex, there is also the tendency for increased inefficiency and increase in average cost as the firm expands

Ari said there are three possible outcomes when you spin this spinner twice: two reds, a yellow and a red, or two yellows.

EastWind [94]

Answer:

From inspection of the diagram, we can see that the spinner is divided into <u>4 equal parts</u>, where 3 parts are red and 1 part is yellow.

$\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}$

Therefore,

$\implies \textsf{Probability of getting a red} = \sf \dfrac{3}{4}$

$\implies \textsf{Probability of getting a yellow} = \sf \dfrac{1}{4}$

<u>Multiplication Rule for Independent Events</u>

For independent events A and B:

$\sf P(A\:and\:B)=P(A) \times P(B)$

Therefore,

$\begin{aligned}\implies \sf P(yellow\:and\:yellow) & = \sf P(yellow) \times P(yellow)\\\\ & = \sf \dfrac{1}{4} \times \dfrac{1}{4}\\\\ & = \sf \dfrac{1}{16}\end{aligned}$

<h3><u>Conclusion</u></h3>

Ari is incorrect. The spinner is divided into 4 parts, where only one part is yellow. Therefore, the probability of spinning a yellow is 1/4. As the events are independent, the Multiplication Rule should be used to calculate the probability of spinning 2 yellows. So the probability of spinning 2 yellows is 1/4 x 1/4 = 1/16.
