Answer:

We know that a^2+b^2=c^2. The 45° angle lets us know that y=x (45+45+90=180), so the problem is y^2+x^2=4sqrt of 2

$4 \sqrt{2} = \sqrt{32 } \\ \sqrt{32} ^{2} = 32$

So you get y^2+x^2=32, and from there, since we know x and y are equal, you can just divide 32 by 2 then take the square root of that, so the answer should be 4 for both x and y

(02.02)A train can travel 744 miles in 3 hours. What is the unit rate that this train is traveling per hour? _____ miles per hou

Fynjy0 [20]

If the train travels 744 miles in 3 hours then to determine the unit rate the train is traveling per hour you have to divide the miles by the hours, in this case (744 miles)/(3 hours). The final result concludes as 248 miles per hour.

Step-by-step explanation:

Lateral Area:

We have four congruent triangles with base b = 16cm and height h = 12cm.

The formula of an area of a traingle:

$A_\triangle=\dfrac{bh}{2}$

Substitute:

$A_\triangle=\dfrac{(16)(12)}{2}=(8)(12)=96\ cm^2$

$L.A.=4A_\triangle=4(96)=384\ cm^2$

Surface Area:

$S.A.=B+L.A.$

In the base we have the square with side s = 16cm. The formula of an area of a square:

$A_\square=s^2$

Substitute:

$B=16^2=256\ cm^2$

$S.A.=256\ cm^2+384\ cm^2=640\ cm^2$

Which description compares the domains of function A and Function B correctly?

kykrilka [37]

Answer:

Choice B is correct; the domain of function A is the set of real numbers greater than 0

The domain of the function B is the set of real numbers greater than or equal to 1

Step-by-step explanation:

The domain of a function refers to the set of x-values for which the function is real and defined. The graph of function B reveals that the function is defined when x is equal 1 and beyond; that is its domain is the set of real numbers greater than or equal to 1.

On the other hand, the natural logarithm function is defined everywhere on the real line except when x =0; this will imply that its domain is the set of real numbers greater than 0 . In fact, the y-axis or the line x =0 is a vertical asymptote of the natural log function; meaning that its graph approaches this line indefinitely but neither touches nor crosses it.

Answer:

1.Triangle is heavier than a square.

2.Circle is lighter than the triangle and square.

3.3 squares won't be balanced between one triangle.

Step-by-step explanation:

Imagine Triangle is 10 and Square is 3

Triangle is heavier.

Imagine Circle is 1

3+3+3=9 also 3 squares

3 squares + 1 circle = 10

as one circle equals 1.
