30.4

Answer:

9.5 m

Step-by-step explanation:

If width is -- x

12.4 + x + 12.4 + x = 43.8

2x = 19

Answer:

The area of rectangle is "31 units²".

Step-by-step explanation:

The given values are:

Length of rectangle,

= [tex]\frac{21}{7}[/tex]

Width of rectangle,

= [tex]\frac{31}{3}[/tex]

As we know,

The area of rectangle is:

=  [tex]Length\times width[/tex]

On substituting the values, we get

=  [tex]\frac{21}{7}\times \frac{31}{3}[/tex]

=  [tex]\frac{217}{7}[/tex]

=  [tex]31 \ units^2[/tex]

Step-by-step explanation:

Answer:

200

Step-by-step explanation:

Mr. Jacob's class reads every day for 20 minutes, which ends up being 20 * 28 because there are 28 days in four weeks. That equals 560

Mrs. Clark's class reads 3 days a week for 4 weeks, so 3*4 = 12. The number of minutes her class reads is 30 minutes so 30*12 = 360.

560-360=200

The perimeter of the triangle is 188.1 m

The perimeter of a triangle can be determined by adding the three lengths of the triangle.

From the image, the coordinates of vertices of the triangle are:

(-3, 3), (-3, -2) and (3, 3)

distance between (-3, 3) and (-3, -2) is:

3-(-2) = 5  (we use y coordinates only because x are the same)

       = 50 m  (Each unit on the map represents 10 meters)

distance between (-3, 3) and (3, 3) is:

3-(-3) = 6    (we use x coordinates only because y are the same)

       = 60 m

distance between (3, 3) and (-3, -2) is:

= √(50² + 60²)     (Pythagoras)

= 78. 1 m

Perimeter = 50 + 60 + 78.1 = 188.1 m

Answer:

the perimeter is

104/5 feet or 20 4/5 ft

Step-by-step explanation:

The perimeter is a loop that surrounds, circumscribes, nor defines a two-dimensional shape and a one length.

A park's sandbox measures [tex]20 \ \text ft[/tex] in diameter at its base.

Todd's sandbox has a [tex]4 \ \text ft[/tex] base.

Now [tex]\frac{4}{20}=\frac{1}{5}\\\\[/tex]

As a result, the scale factor for smaller sandboxes is [tex]\ \frac{1}{5}\\\\[/tex]

[tex]\to 14 \times \frac{1}{5} = 2.8\\\\\to 18 \times \frac{1}{5}= 3.6\\\\[/tex]

As a result, in Todd's sandbox, the missing lengths (in feet) are 2.8 and 3.6.

Todd's sandbox has a perimeter of [tex]4 + 2.8 + 3.6 = 10.4[/tex] feet.

========================================================

Explanation:

m = mass

v = volume

d = density

The formula we use is

d = m/v

Multiplying both sides by v allows us to solve for m

d = m/v

d*v = m

m = d*v

Now plug in the given density (d = 4) and the given volume (v = 15) and simplify:

m = d*v

m = 4*15

m = 60 grams

Note how,

d = m/v

d = 60/15

d = 4

Answer:

-112.5

Step-by-step explanation:

2x - 50 = -275

2x = -225

x = - 112.5

Answer:

x = -225/2 (or) -112.5

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ -275 = 2x - 50

Then the value of x will be,

→ -275 = 2x - 50

→ 2x - 50 = -275

→ 2x = -275 + 50

→ 2x = -225

→ x = -225/2

→ [ x = -112.5 ]

Hence, value of x is -112.5.

Step-by-step explanation:

she gave 5 oranges to her husband .

A statement that links two expressions with an equal sign is called an Equation.

It is given that

Aunt Mansah bought 100 oranges

she bought 4 oranges for 20p

1 is bought at 5p

Let x be the number of oranges she gave to her husband

The remaining oranges were sold at 5 for 40p

1 is sold at 8p

Profit = £2.60

The given data can be used to form equation and solving them will give desired answers

1 pound = 100 pence

( 100 - x) * 8 - ( 100) * 5 = 2.60 * 100

800 - 8x -500 = 260

-8x +300 = 260

8x = 40

x = 5

Therefore she gave 5 oranges to her husband .

Answer:

105 sqaure kilameters

Step-by-step explanation:

Answer:

94.86 miles per hour

Step-by-step explanation:

The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)

The appropriate customary unit is calculated as:

1 km = 0.62 miles

153 km = x

Cross Multiply

x = 153 × 0.62 miles

94.86 miles

Therefore, the appropriate customary unit is 94.86 miles per hour
