The diagram shows the intersections of several straight roads. The avenues run parallel to each other.

valina [46]

By applying the property of similar triangles, the distance Amana from point A to B walked is: B. 226 ft.

<h3>How to determine the distance?</h3>

By critically observing the diagram (see attachment), we can deduce that two (2) similar triangles were formed by the First Ave. and Second Ave.

By applying the property of similar triangles, the distance Amana walked is given by:

(AB + 113)/113 = (280 + 140)/140

(AB + 113)/113 = 420/140

(AB + 113)/113 = 3

AB + 113 = 3 × 113

AB + 113 = 339

AB = 339 - 113

AB = 226 ft.

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).

ivanzaharov [21]

Answer: The value of x is -5 and the value of y is 5.

Explanation:

The slope of the line is $\frac{2}{3}$ and the point is (-2,5) from which the line line is passing.

If a line is passing through the point $(x_1,y_1)$ with slope m, the the equation of line is,

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

$y-5=\frac{2}{3}(x+2)$

$3y-15=2x+4$

$3y-2x=19$ ..... (1)

It is given that the point A(x,3) and B(-2,y) lies on the line. It means it satisfies the equation of the line.

Put y=3 in equation (1).

$3(3)-2x=19$

$-2x=10$

$x=-5$

The value of x is -5.

Put x=-2.

$3y-2(-2)=19$

$3y+4=19$

$3y=15$

$y=5$

The value of y is 5.

lidiya [134]

Answer: This equation is not a function.

Step-by-step explanation:

Ok, a function is something like a "machine".

It takes an input value, x, and transforms it into an output value, y.

Such that for every input x, the function can transform it into only one value of y.

for example, if we have a "function" f(x)

such that f(2) = 3 and f(2) = 4

(for the same input, x = 2, we have two different outputs)

Then this is not a function.

Now, the given equation is:

x^2 + y^2 = 5

This is actually the equation for a circle, centered at the point (0, 0) and with a radius equal to √5.

Then, if we want to transform it into y(x), we can see a problem

If x = 0, we have:

0^2 + y^2 = 5

y^2 = 5

then we have two possible values for y:

y = +√5

y = -√5

Then for one value of x, we have two values of y.

This means that this is not a function.

Anna [14]

Answer: 495 bacteria in 2 minutes.

Step-by-step explanation:

We would apply the formula,

y = ab^t

Where

a represents the initial amount of bacteria.

t represents the doubling time.

From the information given

a = 10

t = 15 seconds

Since after 15 seconds, the amount of bacteria multiplies by 2, then

y = 2 × 10 = 20

Therefore

20 = 10 × b^15

Dividing through by 10, it becomes

2 = b^15

Raising both sides of the equation by 1/15, it becomes

2^(1/15) = b^15/15

b = 1.047

The equation becomes

y = 10(1.047)^t

For t = 2 minutes(2 × 60 = 120 seconds), then

y = 10(1.047)^120

y = 495 bacteria
