Which statements are true about tessellations?

1 answer:

6 0

The correct answer is 1,3& 4.

A figure can tessellate only if its interior angle is a factor of 360. For an equilateral triangle, each interior angle is 60°; 360÷60 = 6, so this works.

For a regular hexagon, each interior angle is (6-2)(180)/6=4(180)/6=720/6=120; 360÷120=3, so this works.

For a regular pentagon, each interior angle is (5-2)(180)/5=3(180)/5=540/5=108; 360÷108=3.3. This does not divide evenly, so it does not work.

For a square, each interior angle is 90°; 360÷90=4, so this works.

Erin’s car uses 6 gallons of gas for every 138 miles she drives.which equation could be used to find how many gallons,g, Erin ne

gladu [14]

The equation that could be used to find how many gallons Erin would need to drive 92 miles is 92 = 23g (option c)

<h3>How many gallons is needed to drive 92 miles?</h3>

The first step is to determine the gallons needed to drive 1 mile. To do this, divide the 6 gallons by 138 miles. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.

Gallons needed for 1 mile = 6/138

In order to determine the gallons needed for 92 miles, multiply the ratio gotten in the previous step by 92

(6/138) x 92 = 4 gallons

The option that gives 4 gallons is : 92 = 23g

g = 92 / 32 = 4

Question 12.12. In 2010, the population of a city was 65,903. It was expected to grow at a rate of 0.7% each year.

postnew [5]

$y=Ce^{kx}$

k=0.7%=0.007

$65903=Ce^{.007(0)} \\ 65903=Ce^0 \\ 65903=C(1) \\ C = 65903$

$y=65903e^{0.007(2027-2010)}\\y=65903e^0.229 \\ y = 74231.157$

The best answer is 74,200

find the domain and range of the relation (-3,3),(-3,2),(-3,1)(-3,0).Then determine whether the relation is a function

navik [9.2K]

The domain is the x value: (-3)
The range are the y values: (0, 1, 2, 3) in order from least to greatest
No this is not a function because that value of x is "reused". You can "reuse" a y value with different x values but you can't reuse an x value ever, even if the y's are different. x's cannot be the same

Two large numbers of the Fibonacci sequence are F(50)=12,586,269,025 and F(51)=20,365,011,074. If these two numbers are added to

butalik [34]

$F(n)=F(n-1)+F(n-2)$ for $n\ \textgreater \ 1$

So $F(50)+F(51)=F(52)$
