Answers

the number is less than 52 because 52 is 130% of it, if it were 100% they would be the same but there is an extra 30% so 52 is greater than the number and the number is less than 52

marcus can buy 0.3 pound of sliced meat from a deli for $3.15 how much will 0.7 pound of sliced meat cost?

Answers

Answer: The required cost of 0.7 pounds of sliced meat is $7.35.

Step-by-step explanation: Given that Marcus can buy 0.3 pound of sliced meat from a deli for $3.15.

We are to find the cost of 0.7 pound of sliced meat.

We will be using the UNITARY method to solve the problem.

We have

the cost of 0.3 pound of sliced meat = $3.15.

So, the cost of 1 pound of sliced meat will be

$(3.15)/(0.3)=(31.5)/(3)=\$10.5.$

Therefore, the cost of 0.7 pound of sliced meat is

$10.5*0.7=1.05*7=\$7.35.$

Thus, the required cost of 0.7 pounds of sliced meat is $7.35.

$22.05 because $3.15 times 0.7 is= 22.05

21,000 rounded to the nearest 10,000

Answers

The answer would be 20,000 because 21 is closer to 20 than 30.

The answer would be 20,000. Like rounding 21 to the nearest ten is 20 because it is lower than the middle number (25).

a commercial jet and a private airplane fly from Denver to phoenix. it takes the commercial jet 1.1 hours for the flight, and it takes the private airplane 1.8 hours. the speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane. Find the speed of both airplanes

Answers

Answer:

The speed of thecommercial jet is $540mi/h$ while the speed of the private airplane is $330mi/h$

Step-by-step explanation:

Let's name the commercial jet as cj and private airplane as pa, so we know the following:

It takes the commercial jet 1.1 hours for the flight, so:

$t_(cj)=1.1h$

It takes the private airplane 1.8 hours for the flight, so:

$t_(pa)=1.8h$

The speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane:

Let's name the speed of the commercial jet as $v_(cj)$ and the speed of the private airplane as $v_(pa)$ , then:

$v_(cj)=v_(pa)+210$

From physics we know that:

$v=(d)/(t) \n \n Where: \n \n v: \ speed \n \n d: \ distance \n \n t: \ time$

Since the distance from Denver to phoenix is unique, then:

$d_(cj)=d_(pa)=d$

Thus, from the equation $v_(cj)=v_(pa)+210$ and given the relationship $v=(d)/(t)$ we have:

$v_(cj)=v_(pa)+210 \n \n (d)/(t_(cj))=(d)/(t_(pa))+210 \n \n \n Plug \ in \ t_(cj)=1.1 \ and \ t_(pa)=1.8 \ then: \n \n (d)/(1.1)=(d)/(1.8)+210 \n \n Isolating \ d: \n \n d((1)/(1.1)-(1)/(1.8))=210 \n \n (35)/(99)d=210 \n \n d=(99* 210)/(35) \n \n d=594miles$

Finally, the speeds are:

$\bullet \ v_(cj)=(d)/(t_(cj)) \n \n v_(cj)=(594)/(1.1) \therefore \boxed{v_(cj)=540mi/h} \n \n \n \bullet \ v_(pa)=(d)/(t_(pa)) \n \n v_(pa)=(594)/(1.8) \therefore \boxed{v_(pa)=330mi/h}$
