Find the values of X and Y

Mathematics
1 answer:
frutty [35]3 years ago
8 0

Answer:

y is equal to 2 and x is equal to 31 degrees.

Step-by-step explanation:

In order to find this, we must note that similar parts of congruent triangles are congruent. Since y is congruent to the part that is labeled 2, then it is an easy comparison.

x is a bit trickier. For this one, we must find the missing angle of the first triangle. To get that, we must subtract the given angle and the right angle from 180. This will give us x.

180 - 59 - 90 = x

31 = x

There are 2,100 bacteria in a circular petri dish. The dish has a radius of 40 millimeters. What is the approximate population d
Alexxx [7]
A petri dish is simply a circle; thus, we use the formula of the area of the circle which is <span>πr^2. 
Given r = 40 mm
A = </span>π(40)^2 = <span>5026.55 sq. mm
</span>
Population density = bacteria count / area
PD = 2,100 / <span>5026.55
PD = </span><span>0.417782 bacteria / mm sq.

Therefore, the answer is approximately 0.418 </span><span>bacteria per square millimeter.</span>

A survey reveals that the sales of smartphones is increasing considerably. The average annual sales of smartphones, in million u
EleoNora [17]

Answer:

when the survey was initially conducted the average sales of smartphones was 1.7 million units

Step-by-step explanation:

The average annual sales of smartphones is given by function

P(n)= 1.7 (b)^n

Exponential growth function is given by

f(x)= ab^x

Where a= initial value

b = growth factor , b= 1+r where 'r' is the growth rate

x is the time period

Now we compare f(x) with P(n)

the value of a= 1.7 that is the initial value.

So we can say, when the survey was initially conducted the average sales of smartphones was 1.7 million units

What is the solution to the system of equations?
Sever21 [200]

Answer:

(-2,\frac{5}{3})

Step-by-step explanation:

Given:

The system of equations given are:

y=\frac{2}{3}x+3\\x=-2

Plug in x=-2 in the first equation and solve for y.

y=\frac{2}{3}(-2)+3\\y=\frac{-4}{3}+3\\y=\frac{-4}{3}+\frac{9}{3}\\y=\frac{-4+9}{3}=\frac{5}{3}

Therefore, the solution is (x,y)=(-2,\frac{5}{3})
