Answer:

1) 6

2)4

3)27

4)126

5)15

Step-by-step explanation:

1. We need to see how many 8-miles are in 24 miles, than multiple it with 2in.

(24/8)*2=3*2=6in

2. Fist we calcue how many 17-feets are in 68feets, and multiple that with 1in.

(68/17)*1=4

3. We first see how many 3ins are in 9ins, and than multiple that with 9feet

(9/3)*9=3*9=27

4. First see how many 2ins are in 36ins, and then multiple it with 7.

(36/2)*7=18*7=126feet

5. See how many 15fts are in 75ft And than multiple it with 3.

(75/15)*3=5*3=15

Answer:

1)6

2)4

3)27

4)126

5)15

Step-by-step explanation:

1) so the ratio given is 2 inch=8 miles.

to make the ratio simpler we can divide it by 2 into 1 inch=4 miles.

(2 inch/2=8miles/2)

now we got (some number) inch= 24 miles

so

1 inch = 4 miles is related to

(some number) inch = 24 miles

now we'll divide 24 miles by 4 miles.

then we'll get the missing inch, which is 6.

to make sure you're correct use the original scale

1:4 and substitute 6 in.

6:(6x4)

6:24#

give up.cuz i see someone with a much simplier and easier to understand answer

The measures of two supplementary angles have a ratio of 4:5. What is the measure of the larger angle?
vladimir1956 [14]

Answer:

100 is larger, that is your answer.

Step-by-step explanation:

First, we know that all supplementary angles add to 180°. Then, since the angles are in the ratio 4:5, we can also represent these angles as 4x and 5x respectively. Both angle measures have the same variable (x) because no matter how large the angles are, they must have a common multiple because they are in a ratio. We can then write the formula 4x+5x=180 and solve for x. First, you combine like terms to get 9x=180. The you divide both sides by 9 to get x=20. Then, we can find both angles to be 80 (4*20) and 100 (5*20) by plugging them into 4x and 5x. Since 100 is larger, that is your answer.

I hope this helps.

Suppose that two defective refrigerators have been included in a shipment of six refrigerators. the buyer begins to test the six
Verdich [7]

a) Answer: 0.2 <span>

consider the 4 refrigerators that waschosen out of the 6. There are 6*5*4*3 ways to choose these refrigerators (not 6choose4, since refrigerators are distinguishable). Therefore the denominator of our probability is 360. 

The numerator is a bit harder. Consider the first 3 refrigerators that was chosen. 2 were good, 1 was bad. There are 3choose1 = 3 places that the bad refrigerator can go. In each of these places, we count the number of ways to pick these 3 out of the 6. Since one is good, there are 4 ways (b/c there are 4 good refrigerators) to select the first. Another is also good, so the number of ways becomes 4*3. The last is bad, and there are 2 bad ones, so the number of ways to select these 3 becomes 4*3*2. Do not be confused by the fact that I ordered the above, this is taken care of by multiplying by the 3choose1 from above. Think of it like 4*3*2 + 4*2*3 + 2*4*3. Regardless, there is only one choice for the 4th refrigerator: bad. Thus the number of ways of being able to find the last bad fridge on the 4th test is 3*4*3*2 = 72. 

The probability is then 72/360 = 0.2 

I did the same method for the probability of searching the last bad fridge on the nth trial, and they all added to 1, so I'm pretty sure this is right. 

b) Answer: 0.4 

This probability is equal to: 
P(find on 2nd) + P(find on 3rd) + P(find on 4th) 

You know the third term, and the first two you can find in the same way as I did above. They are 0.06666... and 0.1333333... 

c) Answer: 0.5 

This is P(find on 3rd) + P(find on 4th) 

You know that of the 4 refrigerators left, 3 are good and 1 is bad. So, P(3) = 1/4, because there is a 1 in 4 chance that you choose the bad one right away 

P(4) = 3/4 * 1/3 = 0.5, since there is a 3 in 4 shot you select a good one, then a 1 in 3 that you select a bad one. </span>

<span>So P(3) + P(4) = 0.5</span>

Thomas got a flat tire and had to walk 1/4 mile to the nearest gas station. How many feet did Thomas walk?
dusya [7]

Answer:

1320\ \text{feet}

Step-by-step explanation:

The distance Thomas walked to the nearest gas station is \dfrac{1}{4}\ \text{mile}.

The conversion factor for miles to feet is

1\ \text{mile}=5280\ \text{feet}

So

\dfrac{1}{4}\ \text{mile}=\dfrac{1}{4}\times 5280

=1320\ \text{feet}

Hence, Thomas had to walk 1320\ \text{feet} to get to the nearest gas station.
