Answer:

25.1cm

Step-by-step explanation:

C=2πr

here radius, r=4 cm and π=3.142

Put values in formula.

C=2(3.142)(4)

C=25.1 cm (Rounded to 1 decimal place)

Answer:

25.1 centimeters

Step-by-step explanation:

Formula to find circumference of a circle is C=2πr

Plug in the given values, 3.142 for π, and 4 for r.

C=2 x 3.142 x 4=25.136 centimeters. Round this to 1 decimal place, so our final answer is 25.1

Answer:

[tex]x=44[/tex]

m∠1=118°

m∠2=62°

Step-by-step explanation:

Part A: They are supplementary angles, so

[tex]2x+30+62=180[/tex]

Simplify like terms,

[tex]2x+92=180[/tex]

We subtract 92,

[tex]2x=88[/tex]

Divide by 2,

[tex]x=44[/tex]

Part B:

[tex]m[/tex]∠[tex]1=2x+30[/tex] because ∠2 is vertical to 2x+30.

Plug in 44 for x,

[tex]m[/tex]∠[tex]1=2(44)+30[/tex]

Simplify,

[tex]m[/tex]∠[tex]1=118[/tex]

[tex]m[/tex]∠[tex]2=62[/tex]° because it is a vertical angle to the 62° angle.

Answer:

Solution given:

2x+30+62=180°[linear pair]

2x=180-92°

x=88/2=44°

Now,

<1=2x+30=2×44+30=118°[vertically opposite angle]

<2=62°[vertically opposite angle]

[vertically opposite angle]

Answer: −(3x−2)(x+6)

Step-by-step explanation:

We know it's factored because...

−(3x−2)(x+6)

If we multiply, then we get what we started with.

-3x * x = -3x^2

2 * x = 2x

-3x * 6 = -18x

2 * 6 = 12

-3x^2 - 18x + 2x + 12

-3x^2 - 16x + 12

Answer:

Huh????

Step-by-step explanation:

The number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)

Let we have to add two fractions as:

[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]

Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and  [tex]b_2[/tex]. That will help to make the denominators same.

Once the denominators become same, the numerators can add up directly, giving us the final result of addition.

For this case, we're given that:

For 5 days, the total distance her dog walked = 2/3 + 2/3 + 2/3 + 2/3 + 2/3

Since denominators are same, thus:

[tex]\dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} = \dfrac{2+2+2+2+2}{3} = \dfrac{10}{3}[/tex]

We could've easily done it as: 2/3 + 2/3 + 2/3 + 2/3 + 2/3 = 5 times 2/3 = [tex]5 \times \dfrac{2}{3} = \dfrac{5 \times 2}{3} = \dfrac{10}{3}[/tex]

Thus, the number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)

Answer:

7.5 fluid ounces

Step-by-step explanation:

Fraction of fluid ounce poured into each test tube

Number of test tubes filled = 10

The number of fluid ounces poured is the product of the amount poured into each test tube and the number of test tubes filled

Therefore, total amount poured :

(3/4 fluid ounces) * 10

0.75 * 10

= 7.5 fluid ounces

Answer:

2 and 3

Step-by-step explanation:

To simplify this expression, you will need to use the distributive property.

Multiply -2/5 by 15 = - 6, -2/5 by -20d = 8d, and -2/5 by 5c = -2c.

you can switch these around to get -6 + 8d - 2c and -2c + 8d - 6.

Answer:

Step-by-step explanation:

Let the expression representing a situation is,

y = 6a + 2(c - b)

Where, a, b and c are the constants

If a = 2, b = 1 and c = 9

By substituting these values in the expression,

y = 6(2) + 2(9 - 1)

y = 12 + 16

y = 28

Therefore, for all given values of the constants value of y is 28.

Answer:

14%

Step-by-step explanation:

Given :

Bear voters = 14

Lion voters = 86

Percentage of students who voted bear :

(Bear voters / total number of Voters) * 100%

Total number of voters = (bear voters + lion voters) = (14 + 86) = 100

Percentage of students who voted bear :

(14 / 100) * 100%

0.14 * 100%

= 14%

Answer:

  time to max height: 2.5 seconds

  max height: 104 ft

  range of function: [4, 104]

Step-by-step explanation:

The equation for ballistic motion is ...

  h(t) = -16t^2 +v0·t +h0 . . . . where v0 is the initial upward speed and h0 is the initial height

For the given parameters, the height function is ...

  h(t) = -16t^2 +80t +4

The time for maximum height is ...

  -b/(2a) = -80/(2(-16)) = 2.5 . . . seconds

The maximum height is ...

  h(2.5) = (-16·2.5 +80)(2.5) +4 = 104 . . . feet

The range of the function is from the minimum height (at launch) to the maximum height:

  4 ft ≤ h(t) ≤ 104 ft.

Answer:

Step-by-step explanation:

b = 20 °

c = 160°    ( b/c 180-20 = 160 )  :)

Use csc (90) = 10/m.

So, m = 10/csc(90).

m = 8.93997

Answer:

m = 8

Step-by-step explanation:

Here's your solution

=> in traingle DHF and traingle EGF

we have angle DHF and EGF = 90°

and angle F is common , so both traingle are similar by AA similarity

=> 12/m = 15/10

=> m = 120/15

=> m = 8
