Answer:

24 square units

Step-by-step explanation:

When the sides are doubled, new figure so obtained will have:

Base (b) = 2*3 = 6 units

Height (h) = 2*4 = 8 units

Area of the figure when each sides are doubled

[tex] = \frac{1}{2} \times b \times h \\ \\= \frac{1}{2} \times 6 \times 8 \\ \\ = 3 \times 8 \\ \\ = 24 \: square \: unite[/tex]

Answer:

P = 56.562

Step-by-step explanation:

Perimeter of a semicircle:

P = πr + 2r

Given:

r = 11

Work:

P = πr + 2r

P = 3.142(11) + 2(11)

P = 34.562 + 22

P = 56.562

Answer:

[tex]r=20.1[/tex]

Step-by-step explanation

[tex]C=\pi d[/tex]

Green car circumfrence = 126 feet

Plug in numbers

[tex]126=3.14d[/tex]

Divide both sides by 3.14

[tex]\frac{126}{3.14} = 40.12...[/tex]

Divide diameter by 2 to find radius

[tex]\frac{40.1}{2} = 20.05[/tex]

round up to [tex]20.1[/tex]

Answer:

Equation 1 would be: 3a+2C

Equation 2 would be: 5a+3C

Step-by-step explanation:

Answer:

AB and CD are parallel lines.

hence answer is D

Good day mate

Answer:

The numbers are 6 and 2

6 squared = 36

2 squared = 4

So 36-4 = 32

And 36 x 2 = 72 + 4 = 76

First, write the expression. Then solve.

9 x 10^-9

9 x 0.0000000010

0.000000009

Its b In normal form of a straight line, the equation is given by where p is the perpendicular distance of the line from the origin and  is the angle between the perpendicular line and the positive direction of the x-axis.

Answer:

P(for) = 5/8

P(against) = 3/10

P(undecided)= 3/40

Step-by-step explanation: Again, find the total number of people Devi surveyed.

40 people got surveyed in total. So P(for) means to find how many people wanted to vote for the mayor. In the table, it says 25 voted for the current mayor. So 25/40. Then we can simplify it to 5/8.

Then find how many people voted against her. 12 people voted against her. 12/40 is 3/10.

Finally, find how many people were indecisive. 3 people were indecisive. 3/40. We cannot simplify it, so leave it like that. Hope this helps.

Answer:

1 < n

Step-by-step explanation:

3(3 - 4n) + 6n < -2n + 5

9 - 12n + 6n < -2n + 5

9 - 6n < -2n + 5

9 < 4n + 5

4 < 4n

1 < n

I hope this is accurate and helpful. Please let me know if it’s correct! It’s been a while since I’ve done inequalities.

Answer:

1) 18 inches

Step-by-step explanation:

By the Midsegment Theorem: A midsegment connecting two sides of a triangle is parallel to the third side and is half as long the third side.

ans: 36/2 = 18

Answer:

they do- here's how (i think)

Step-by-step explanation:

a toad has similar features- think about it.

a toad has gills since it needs to stay underwater for the time being

so do fish

they have a tail to let them swim around and direct themselves to which area they're going to.

fish also do the same!

hope this helps!:)

Answer:

  (c)  y=(1/2)(360−152) because you subtract the arc measure from 360° and then multiply by one-half.

Step-by-step explanation:

The inscribed angle y is half the measure of the intercepted arc. That arc is the difference between 360° and 152°. So, y is ...

  y = 1/2(360° -152°)

Answer:

area = 84 m²

Step-by-step explanation:

area = (1/2)(4)(3)(2) + (5)(6) + (6)(3) + (4)(6) = 84 m²

Answer:

4x-20

Step-by-step explanation:

2+5x-1x-22

First, rearrange to make life temporarily easier.

5x-1x+2-22

Then combine like terms.

5x-1x=4x

2-22=-20

So we have 4x-20

That is simplified as far as it can.

Answer:

$150

Step-by-step explanation:

The formula we'll use for this is the simple interest formula, or: I= p * r * t

Step-by-step explanation:

angle j + angle JKL + angle KLJ = 180(sum of angles in a triangle)

[tex]j + 94 + 41 = 180 \\ j + 135 = 180 \\ j = 180 - 135 \\ = 45[/tex]

Arc Length s =

given r = 10 units,

[tex] = (\frac{j}{360} ) \times 2\pi \: r \\ = ( \frac{45}{360} ) \times 2\pi(10) \\ = 0.125 \times 20\pi \\ = 2.5\pi \\ = 7.85units(nearest \: hundredth)[/tex]

Answer:

7.85 units
