Try It! Class A was given a sunflower with a height of 8 centimeters that grows at a rate of 3 1/2 centimeters per week. Class B

Answer:

8 Weeks

Step-by-step explanation:

First let's collect the given data:

• Class A:

- Starts at 8 cm

- grows at 3.5 cm/week

• Class B:

- Starts at 10cm

- grows at 3.25 cm/week

Class B's plant starts out 2 cm taller and Class A's plant grows 1/4 cm faster. So, to find when these two will be at an equal height, divide 2 cm by 1/4.

2 ÷ 1/4 =

2 × 4/1 =

2 × 4 =

It will take 8 weeks for the plants to be at an equal height.

A special Olympic event has 16 more boys than girls competing. The total number of participants is 1000. How many boys completed

Ray Of Light [21]

x= the number of girls competing

x+16=the number of boys competing

The equation to find the number of boys and girls competing would be:

x+(x+16)=1000

First, combine like terms:

2x+16=1000

Subtract 16 from both sides.

2x=984

Divide both sides by 2:

x=492

We know now that the number of girls competing is 492. To find the number of boys competing, you simply have to add 16 to 492.

492+16=508

There are 508 boys competing and 492 girls competing.

I hope this helps :)

★ ∆ ABC is similar to ∆DEF

★ Area of triangle ABC = 64cm²

★ Area of triangle DEF = 121cm²

★ Side EF = 15.4 cm

${\large{\textsf{\textbf{\underline{\underline{To \: Find :}}}}}}$

★ Side BC

${\large{\textsf{\textbf{\underline{\underline{Solution :}}}}}}$

Since, ∆ ABC is similar to ∆DEF

[ Whenever two traingles are similar, the ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides. ]

$\therefore \tt \boxed{ \tt \dfrac{area( \triangle \: ABC )}{area( \triangle \: DEF)} = { \bigg(\frac{BC}{EF} \bigg)}^{2} }$
