Valerie is 30 inches tall and casts a shadow that is 12
inches long. At the same time, ber teddy bear casts a
shadow that is eight inches long. How tall is the teddy
bear?

Answers

Answer:

20

Step-by-step explanation:

30:12 is the original ratio. So if you divide both sides by the numbers' GCF of 6 you'll get a simplified ratio of 5:2. Then multiply both sides by 4 to keep the ratio constant, then you'd get 20:8. So when the teddy bear casts a shadow of 8 inches long the actual teddy bear is 20 inches tall. Hope this helps!

Step-by-step explanation:

6*z-7-(8*z+2)>0

  -2z - 9  =   -1 • (2z + 9

Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

     2z+9  < 0

Divide both sides by  2  

     z+(9/2)  < 0

Subtract  9/2  from both sides

           z < -9/2

Please help quick

Answers

Answer $100 each

Step-by-step explanation:

2500/25

Answer:  2500/25

Each member pays $100

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

Explanation:

The slash symbol means division. It's the same as saying 2500 ÷ 25

The expression 2500/25 simplifies to 100, which means that each member must pay $100. If you had 25 members paying $100 each, then 25*100 = 2500 dollars is the total amount of money paid.

So in short, you divide the total cost over the number of members.

divide 120 in the ratio of 1 : 4​

Answers

if you add your two ratios 1:4 you find your total amount of ratio which is 5. Now you divide the total by the ratio total: 120/5 = 24. This gives you 1 part of 120 so your other part you can find out two ways either by doing 24x4= 96 or by doing 120-24=96 so the ratio becomes 24:96

Dividing 120 in the ratio of 1 : 4 will give 24 and 96.

The first number that'll be gotten based on the information given will be:

= 1/5 × 120

= 24

The second number that will be gotten based on the information given will be:

= 4/5 × 120

= 96

Therefore, the numbers will be 24 and 96.
