Answers

Answer 1

Answer:

Option 2 is correct .

Step-by-step explanation:

Given : A big cube 5*5 which contains small 25 cubes

Solution :

Let 25 small cubes denotes 100%

So , 1% is denoted by : [tex]\frac{25}{100}[/tex]

So, 24 % is denoted by :

⇒[tex]\frac{25*24}{100}[/tex]

⇒[tex]6[/tex]

Thus to show 24% on 5*5 , 6 small cubes must be shaded .

In Option 2 , 6 small cubes are shaded.

Hence , Option 2 is correct .

A fair coin is flipped 100 times and the results are recorded in the table below.
Which statement is correct?
A) The theoretical probability of the coin landing on heads is 7/20.
B) The experimental probability of the coin landing on tails is 1/2.
C) The theoretical probability of the coin landing on tails is 1/2.
D) The experimental probability of the coin landing on heads is 13/20.

Answers

C would be correct. A is blatantly wrong, B would be correct if it was referring to the theoretical probability, and D is true of the coin landing on tails NOT heads.

Option C) is the correct statement as the Theoretical Probability of the coin landing on tails is 1/2

What do we mean by theoretical probability?

Theoretical probability is the ratio of favorable outcomes to the total number of outcomes.

What do we mean by experimental probability?

Experimental probability or empirical probability is based on a particular experiment using the same formula.

How do we determine probabilities by the question?

Experimental probability of getting heads

= Frequency of heads/Total observations

= 35/100 = 7/20

Experimental probability of getting tails

= Frequency of tails/Total observations

= 65/100 = 13/20

The theoretical probability of getting a heads

= Favorable outcomes of getting heads/Total possible outcomes

= 1/2

The theoretical probability of getting a tails

= Favorable outcomes of getting tails/Total possible outcomes

= 1/2

When we cross-check with the options,

A) Incorrect, as the Theoretical Probability of the coin landing on heads = 1/2

B) Incorrect, as the Experimental Probability of the coin landing on tails = 13/20

C) Correct, as the Theoretical Probability of the coin landing on tails = 1/2

D) Incorrect, as the Experimental Probability of the coin landing on heads = 7/20

An alloy consists of nickel, zinc, and copper in the ratio 2:7:9. How much of each metal is needed to make 3.6 kg of this alloy?

Answers

Answer

Find out the how much of each metal is needed to make 3.6 kg of this alloy .

To proof

As given

An alloy consists of nickel, zinc, and copper in the ratio 2:7:9 .

This shows that an alloy contains 18 parts and assume one part of alloy be u .

Thus

An alloy consists of nickel = 2u

An alloy consists of zinc = 7u

An alloy consists of copper = 9u

As given

Total weight of alloy = 3.6 kg

Thus equation becomes

2u + 7u + 9u = 3.6

18u = 3.6

[tex]u = \frac{3.6}{18}[/tex]

u = 0.2 kg

An alloy consists of nickel = 2 × 0.2

                                           = 0.4 kg

An alloy consists of zinc = 7 × 0.2

                                        = 1.4 kg

An alloy consists of copper = 9 × 0.2

                                             = 1.8 kg

Hence proved

Final answer:

To make 3.6 kg of alloy in the given ratio, 400 grams of nickel, 1400 grams of zinc and 1800 grams of copper are required.

Explanation:

The question is asking how much of each metal, namely nickel, zinc, and copper, is needed to make 3.6 kg of an alloy with a ratio 2:7:9. To solve this, first, we have to understand that the ratio represents relative amounts of each metal, not their exact weights. The entire alloy is made up of 2 parts nickel, 7 parts zinc, and 9 parts copper - a total of 18 parts. We can find the weight equivalent to one part by dividing the total weight of the alloy - 3.6 kg or 3600 grams - by 18. This gives us 200 grams as the weight of one part. To find the weight of each metal needed, we multiply the weight of one part by the number of parts in the ratio: nickel is 2 * 200 = 400 grams, zinc is 7 * 200 = 1400 grams, and copper is 9 * 200 = 1800 grams.

Lee has a jar of 100 pennies. She adds groups of 10 pennies to the jar. She adds 5 groups. What numbers does she say?

Answers

100, 110, 120, 130, 140, 150. If counting by tens
If Lee starts with 100 pennies and adds groups of 10, the operation is addition. Since she does this 5 times, there is 5 different numbers Lee said.

100 + 10 = 110
110 + 10 = 120
120 + 10 = 130
130 + 10 = 140
140 + 10 = 150

Thus, all of the numbers she said were 110, 120, 130, 140, and 150.

2n+5<13
minus  5 both sides
2n<8
divide by 2
n<4

Answer:

1. Using Backwards Method, we get,

We have the inequality 2n+5<13.

So, we subtract both the sides by 5,

i.e. 2n+5-5<13-5

i.e. 2n < 8

Now, divide both sides by 2, we get,

[tex]\frac{2n}{2} <\frac{8}{2}[/tex]

i.e. n < 4.

So, using the Backwards method, we get the solution is n<4.

2. Now, we use the Algebraic method,

We have, 2n+5<13

Take 5 to the right side of the inequality,

i.e. 2n<13-5

i.e. 2n < 8

Now, take the 2 on the right side of the inequality.

i.e. [tex]n<\frac{8}{2}[/tex]

i.e. n < 4.

So, again using the Algebraic Method, we get that the solution is n<4.

Five less than the product of a number n and -6 is at least 8.

A) 5-(-6n)≥8
B -n/6-5≥8
C) -6n-5≥8

Answers

The answer will be C.

The required inequality is -6n - 5 ≥ 8. Option (C) is correct.

What is inequality?

Inequality shows relation between two expression which are not equal to each others.

Given that,

When 5 is subtracted from the product of number n and -6 is at least 8.

The product of number n and - 6  = -6n

Subtract 5 from product of number n and -6 = -6n - 5

To write the inequality that shows that 5 less than -6n is at least 8,

Implies that, -6n - 5 can be grater than or equal to 8.

The inequality can be expressed as,

-6n - 5 ≥ 8

Hence, option (C) is correct.

Kelly Ann took 15 minutes to walk from her home to the library. Her average speed was 3 miles in 45 minutes. how far was it from Kelly Ann's house to the library? (PLEASE SHOW STEPS!!)

Answers

Ok; Since we know that in 45 min, she can walk 3 miles, we can divide it to see how many minutes it takes for her to walk 1 mile. 45 divided by 3 is 15. Which means it takes her 15 minutes to walk 1 mile. If we look back at the beginning, it says she takes 15 minutes. Now that we know that it takes her 15 minutes to walk 1 mile, the answer is that it takes her 1 mile to walk to the library.
Really simple.

You know that speed is v = d/t
so 3/45 = 1/15  or 1 mile per 15 mins

So since she took 15 mins i know the library is 1 mile
