Answer:

20 units

Step-by-step explanation:

1) find the side of the first square

side = P / 4 = 12:4 = 3 units

2) find the side of the second square

side = P / 4 = 16 : 4 = 4 units

3) use the Pythagorean theorem to find the hypotenuse of the right triangle

[tex]\sqrt{4^2 + 3^2} = \sqrt{16 + 9} = \sqrt{25} = 5[/tex] units

4)  find the perimeter of the third square

P = side x 4 = 5 x 4 = 20 units

Answer:

20 units

Step-by-step explanation:

Answer:

the answer is 5

Step-by-step explanation:

the ratio is 4:1 so if you increase B to 20 you divide by 4 to get 5.

20:5=4:1

Answer:

Step-by-step explanation:

All she needs to know is that  a reflection across the x-axis is when the x coordinate stays the same and the y-coordinates change.

Hope this helped.

Answer:

To find the reflection of a point across the x-axis and the y-axis, change the signs of both the x-coordinate and the y-coordinate.

Answer:

102,9 cm^2

Step-by-step explanation:

First of all we can find the area of the two rectangles at the sides of the figure

A rectangle = length x width = 8 x 4 = 32 cm^2

the rectangles are two so:

32 x 2 = 64 cm^2

for the figure in the center we can proceed like this: we can initially assume that also it is a rectangle, so we have to find the length

length = 16-8 = 8 cm

A = 8^2 = 64 cm^2 (so we have discovered that is a square)

if we look we can see that there is also a semicircle that is not part of the figure. We have to find its area and subtract it to the area of the square

A semiciricle = (radius^2 π)/2

radius = 8/2 = 4 cm

A semicirlce = (4^2) π/2 = 25,13 cm^2

64 - 25,13 = 38,87 cm^2

At least we have to added up this value to the area of the two rectangles

total area = 38,87 + 64 = 102,87 = 102,9 cm^2

Answer:

There will be total 855 flowers.

Step-by-step explanation:

Suppose there are 9 total rows and each row has total 19 plant and each plant has 5 flowers.

Then the number of  flowers can be found out by simply multiplying

9*19*5= 855

There will be total 855 flowers (if the above given numbers assumed are the same as the original question)

IF the numbers are changed from the above assumed numbers even then the answer can be obtained by simply multiplying the numbers to get the total numbers of flowers.

Given:

A figure of an isosceles trapezoid with bases 18 and 24, and the vertical height is 4.

To find:

The legs of the isosceles trapezoid.

Solution:

Draw another perpendicular and name the vertices as shown in the below figure.

From the figure it is clear that the AEFD is a rectangle. So,

[tex]EF=AD=18[/tex]

Since ABCD is an isosceles trapezoid, therefore in triangle ABE and DCF,

[tex]AB=DC[/tex]               (Legs of isosceles trapezoid)

[tex]AE=DF[/tex]                (Vertical height of isosceles trapezoid)

[tex]m\angle AEB=m\angle DFC[/tex]             (Right angle)

[tex]\Delta ABE\cong \Delta DCF[/tex]                (HL postulate)

[tex]BE=CF[/tex]                (CPCTC)

Now,

[tex]BE+EF+FC=BC[/tex]

[tex]2BE+18=24[/tex]

[tex]2BE=24-18[/tex]

[tex]2BE=6[/tex]

[tex]BE=3[/tex]

Using Pythagoras theorem in triangle ABE, we get

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex](AB)^2=(AE)^2+(BE)^2[/tex]

[tex](AB)^2=(4)^2+(3)^2[/tex]

[tex](AB)^2=16+9[/tex]

[tex](AB)^2=25[/tex]

Taking square root on both sides, we get

[tex]AB=\pm \sqrt{25}[/tex]

[tex]AB=\pm 5[/tex]

Side length cannot be negative. So, [tex]AB=5[/tex].

Therefore, the length of legs in the given isosceles trapezoid is 5 units.

Answer: 1249 hrs

Step-by-step explanation:

Sophia walked for 12 km to get to her aunt's house.

She did this at a speed of 5km/h which means that the time taken was:

Time = Distance / Speed

= 12 / 5

= 2.4 hours

2.4 in hours:

= 0.4 * 60 minutes

= 24 minutes

= 2 hours 24 minutes

If she left at 1025, she would arrive at:

= 1025 + 2 hours 24

= 1249 hrs

Answer:

Mira = 95 miles

Step-by-step explanation:

Given

John walked 50 miles than Mira

The total miles walked is 290

To find

If John walked 50 miles more than Mira and the total miles walked including Mira is 290, then divide 290 by both of them. Once that is done, don't evenly distribute the miles to them. Because remember, John walked 50 miles more than Mira. So we just distribute this with John having 50 miles more. By subtracting 50 from Mira's share and give it to John

Solve

290 ÷ 2 = 145

Mira's 145 - 50 = 95

John's 145 + 50 = 195

Therefore, John ran 195 miles and Mira ran 95 miles.

There is no value in the hundreths place

So 0 hundreths

Answer:

$300

Step-by-step explanation:

$400 is 100% of the price

25% is  a quarter of 100%

A quarter of 400 is 100 so the discount was    $100

400-100 =300
