Answers

Answer 1

Answer:

Step-by-step explanation:

20 hm = 2000 m

3,412 mm = 0.003412 km

0.25 m = 250 mm

590 mg = 0.59 g

75cm = 0.75 m

12.5 m = 0.0125 km

8,808 cm = 0.08808 km

20 hm = 2000000 mm

1,235g = 1.235 kg

12 decimeters = 0.12 dam

20 L = 20000 mL

13.6 mL = 0.0136 L

Hope this helps :)

Answer 2

Answer:

See below.

Step-by-step explanation:

Let's review the metric prefixes used in this problem:

m = 1/1000

h = 100

c = 1/100

k = 1000

da (deca) = 10

20 hm = 20 × 100 m = 2,000 m

3,412 mm = 3412/1000 m × 1 km/(1000 m) = 0.003412 km

0.25 m = 0.25 m × 1000 mm/m = 250 mm

590 mg = 590 mg × 1 g / (1000 mg) = 0.59 g

75 cm = 75 × m/100 = 0.75 m

12.5 m = 12.5 m × 1 km / 1000 m = 0.0125 km

8,808 cm = 8,808 cm × 1 m / 100 cm × 1 km / 1000 m = 0.08808 km

20 hm = 20 × 100 m × 1000 mm/m = 2,000,000 mm

1,235 g = 1,235 g × kg/(1000 g) = 1.235 kg

12 dm = 12 dm × 1 m / 10 dm × 1 dam / 10 m = 0.12 dam

20 L = 20 L × 1000 mL/L = 20,000 mL

13.6 mL = 13.6 mL × 1 L /  1000 mL = 0.0136 L

A school fundraiser has a minimum target of $600. Faculty donated $200 and there are 10 student clubs that are participating with different activities. Write an inequality showing the amount money each club should raise to meet the minimum target. Use f for the amount of money that each club raises.

Answers

Answer:

600=10f+200

Step-by-step explanation:

since $600 is the target, and the faculty already donated 200 dollars 200 would be the y intercept. since f is the amount of money that the clubs should raise, we can set that as 10 f since there are 10 clubs and since it needs to be inequality, it would be written in the y = mx + b format. hope this helps!

Answer:

b. the second and third one

Step-by-step explanation:

a. 11x-3x-10x=18x, so the first one is definitely the answer. If you look at the last one, you can see that 10x+8x also equals 18x. The other options do not equal 18x, so those can be eliminated.

b. If you distribute the 3 outside of the parentheses, you can see that the expression 3(1+3y) equals 3+9y (because 3*1=3 and 3*3y=9y). So, the third one can be determined to be one of the answers. We can see that the second one also simplifies to be 3+9y, so this one can also be determined to be the answer. The other ones can be eliminated because they do not equal 3+9y.

The mass of a basket containing 3 balls was 3.64 kilograms. The mass of the same basket and 5 balls is 5.26 kilograms. Find the mass of the empty basket in kilograms.

a. the mass of a empty basket is ___
b. explain your answer (in short)

please help

Answers

Answer:

mass of empty basket: 1.21 kg

Explanation:

the mass of basket is constant. Let the mass of basket be "b" and mass of each balls be "m"

Make equations:

b + 3(m) = 3.64  ___ equation 1b + 5(m) = 5.26  ___ equation 2

solve them simultaneously,

3.64 - 3(m) = 5.26 - 5(m)-3(m) + 5(m) = 5.26 - 3.642(m) = 1.62m = 0.81 kg

mass of basket,

b = 3.64 - 3(m)3.64 - 3(0.81 )1.21 kg
Bucket be xballs be y

Now

x+3y=3.64=>x=3.64-3y--(1)x+5y=5.26=>x=5.26-5y

So

3.64-3y=5.26-5y-3y+5y=5.26-3.642y=1.62y=0.81kg

So

x=3.64-3(0.81)=3.64-2.43=1.21kg

Irene wants to use equivalent ratios to solve 3,712÷64, but she can't remember how. Show Irene what to do.

Answers

Answer:3,712÷64=58

Step-by-step explanation:

Answer: The ratio is 58:1, and the division is = 58. Scroll for solving, check, and notes.

Explanation:

What we know:

The question wants us to use equivalent ratiosThe numbers 3,712 and 64 have common denominatorsAn equivalent ratio is a ratio that is something of a simplified form of large numbers, written in a fraction, with a colon, or with the word 'to'

How to solve:

    We need to find the equivalent ratio of 3,712 and 64, and then solve the question based on that.

Process:

Finding equivalent ratios

Set up equation                                                     3712/64

Rewrite into colon-ratio form                                3712:64

Divide by common denominator                         /64  /64*

                                                                               

Solution:                                                                     =58:1

*Read bottom of notes to find out how I found this denominator

Answer: The ratio is 58:1; the solution to the division is 58.

Notes:

There is no way to always know the ratio's common denominator. However, there are some general rules of thumb that may help:

-All numbers have a common denominator of 1. Sometimes, that's the most simplified form.

-All even numbers (Those that end in {0, 2, 4, 6, or 8}) have a common denominator of 2

-All numbers whose digits add up to {3, 6, or 9} (such as 12: 1+2 = 3) have a common denominator of 3.

-These three numbers serve as basic building blocks. You can keep simplifying with them until you get to a prime number. Let's use our problem as an example:

3712 and 64 - both are even, simplify by 2

1856 and 32 - both are even, simplify by 2

928 and 16   - both are even, simplify by 2

464 and 8    - both are even, simplify by 2

232 and 4    - both are even, simplify by 2

116 and 2      - both are even, simplify by 2

58 and 1       - there is a prime number, so this is the simplest form.

Now we take all of our simplifications: 2^6. 2^6 = 64, so the common denominator is 64.

Check:

Our ratio, 58:1, is the simplified form of 3,712 div. 64. This is seen better by rewriting both into a fraction-ratio form:

58:1                    3712 div. 64

58/1                    3712/64

Luckily, our ratio has a 1 in it. This means that when we multiply the ratio by 64 (what the 1 represents), it should yield the original equation.

3712/64 = 58/1

3712/64 = (58/1)*64

3712/64 = 3712/64

Therefore, 58:1 is the correct ratio.
