Answer:

91

Step-by-step explanation:

given perimeter = 273

perimeter of equilateral triangle = 3a

3a = 273

a = 273/3

a = 91

hence, length of side of the triangle is 91

Answer:

203.67

Step-by-step explanation:

all those numbers are confusing, but this is what i get from the picture

triangle area formula = 1/2 base * height

rectangle area formula = L * W

AB = 1/2 base * height, = 1/2 * 9 * 4, = 18

ab is the same as AB                        =18

C = 8.1 * 4.5                                      = 36.45

D = 8.1 * 7.2                                        = 58.32

E = 8.1 * 9                                          = 72.9

added together = 203.67

10 packs of dog toys; or 100 dog toys all together.

Step-by-step explanation:

If Lauren bought 10 packs of dog toys, and there are 10 dog toys in each pack, you could simply multiply 10•10, which would come out to 100 dog toys.

The size of the angle QUP in the system formed by the equilateral triangle QUR, the equilateral triangle PUT and the square RUTS is equal to 150°.

By Euclidean geometry we know that squares are quadrilaterals with four sides of equal length and four right angles and triangles are equilateral when its three sides have equal length and three angles with a measure of 60°. In addition, a complete revolution has a measure of 360°.

Finally, we must solve the following equation for the angle QUP:

m∠QUR + m∠QUP + m∠PUT + m∠RUT = 360

60 + m∠QUP + 60 + 90 = 360

m∠QUP + 210 = 360

m∠QUP = 150

The size of the angle QUP in the system formed by the equilateral triangle QUR, the equilateral triangle PUT and the square RUTS is equal to 150°. [tex]\blacksquare[/tex]

Answer:

B

Step-by-step explanation:

This is a combination problem. For the first letter, there are 26 possible letters in the alphabet to use. For the second, we cannot use the letter used in the first, so there are only 25 possible letters. Repeat this for the remaining 5 letters.

1st - 26

2nd - 25

3rd - 24

4th - 23

5th - 22

6th - 21

7th - 20

To find the number of possible passwords, simply multiply all these numbers together. 26*25*24*23*22*21*20 = 3,315,312,000. Therefore B is the correct answer.

The wire is attached to the pole at 18 root3 ft high.

We have given that,

A 36-foot guy wire is attached to a utility pole to provide support for the pole. The wire forms a 60° angle with the ground.

This is a right triangle formed of which hypotenuse is

h=36ft.

Angle is θ=60degree

Let P be the height of pole.

Answer:

b

Step-by-step explanation:

the volume (V) of a cone is calculated as

V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius , h is the height )

here diameter = 12 , so r = 12 ÷ 2 = 6 and h = 22 , then

V = [tex]\frac{1}{3}[/tex]π × 6² × 22

   = [tex]\frac{1}{3}[/tex]π × 36 × 22

    = [tex]\frac{1}{3}[/tex]π × 792 ( cancel 3 and 792 by 3 )

Answer:

An exponential model will be the best for the data.

Step-by-step explanation:

If you chart this data (either using a calculator, excel, or an online tool like desmos), it is clear that the curve is exponential.

Furthermore, if you run regression, you can find that the curve [tex]4*2^x[/tex] fits the data quite nicely.

y=-2x+5

First of all we need to determine the slope of the line perpendicular to y = 1/2x - 5 .

The slopes of perpendicular lines are opposite reciprocals.

So we take 1/2 , turn it over , and change it's sign :

[tex]^1/_2\:\:\:--- > ^2/_1\:\:\:--- > 2\:\:\:--- > -2[/tex]

The slope of the line perpendicular to y = 1/2x-5 is -2 .

Since we're also given a point that the line crosses , we can write the line's equation in point - slope form :

y-y₁=m(x-x₁)

y-7=-2(x-(-1)

y-7=-2(x+1)

Now convert to slope intercept :

y-7=-2x-2

add 7 on both sides :

Step-by-step explanation:

The population can be modeled by an exponential function with a growth rate of 1% per month. The time of interest, 5 years, is 60 months.

__

  population = (initial value) × (1 + growth rate per month)^(months)

  p = 3,000,000 × (1.01^60) . . . . . . population in 60 months

0.293263 rounded to the ten thousandths place

=0.2933

Answer:

0.2933

Step-by-step explanation:

0.293263 is the decimal you have to round.

0.293263 (the first 2 is in the tenths place)

0.293263 (the 9 is in the hundredths place)

0.293263 (the first 3 is in the thousandths place)

0.293263 (the second 2 is in the ten-thousandths place)

0.293263 (the 6 is in the hundred-thousandths place)

0.293263 (the second 3 is in the millionths place)

They tell you to round the decimal to the ten thousandths place.

The second 2 is in the ten-thousandth place (0.293263).

To round digits you look at the number to its right, if it is 5-9 you round the number up, if it is 0-9 you leave the number as it is.

The number to the right of the number we're rounding (the 2 in the ten-thousands place) is a 6, 6 is a 5-9 number so we round the ten-thousands place digit up 1 number, (from 2 to 3).

And we have our rounded number 0.2933
