Which ratios form a proportion

Lelu [443]

Answer:

Step-by-step explanation:

To form a proportion, you need two equal ratios.

Divide the numerator by the denominator of all fractions.

Any two fractions that are equal are a proportion.

4/9 = 0.4444...

9/4 = 2.25

Fractions are not equal. Not a proportion.

4/10 = 0.4

10/25 = 0.4

Fractions are equal. Proportion

4/11 = 0.363636...

6/13 = 0.46153846...

Fractions are not equal. Not a proportion.

I can't read the fractions, but do the same I did above.

Divide each numerator by the denominator and compare the decimals. If they are equal its a proportion. If theya re not equal, it is not a proportion.

Two blueberry farms are similar in shape. The ratio of the side lengths of the farms is 4:5, and the smaller farm has a perimete

tatuchka [14]

Answer:

$337.5

Step-by-step explanation:

4:5=360:x 360/4=90 90+360=450 check 360/450=0.8 and 4/5=0.8

4:5=360:450

larger farm perimeter is 450 yards so dig a trench 0.75 per yard

so 450 * 0.75 = $337.5

Hope this helps! :)

each of equal sides of an isosceles triangle is 4cm greater than its height .If the base of triangle is 24 cm ,calculate the per

Montano1993 [528]

<h3>Answer:-</h3>

192 cm²

<h3>Step by step explanation :-</h3>

Let us take the height be x , then its side = x + 4. Now half of base will be 12 cm .

According to Pythagoras Theorem :-

=> base² + perpendicular ² = hypontenuse ²

=> 12² + x² = (x+4)²

=> 144 + x² = x² + 16 + 8x

=> 8x = 144-16

=> 8x = 128

=> x = 128/8

=> x = 16 cm .

Hence the height of ∆ is 16 cm .So the area will be half the product of base and altitude.

= 1/2 * 16 cm * 24cm .

= 192 cm²

<h3>★ Hence the area of the triangle is 192 cm² .</h3>
