1. Adam burns 850 calories when he runs for one hour, suppose he runs 3 hours .

Mathematics
1 answer:
LiRa [457]3 years ago
3 0

Answer:

1. If Adam burns 850 calories per hour

850×3=2550 calories for 3 hours

2. If the original price is 200$ and the discount is 30%

We get:

200 × 30

Which can be written as

200×0.3

=60

So 30% of 200 is 60

now to calculate the new price

200-60=140$

The new price is 140$

Find the distance between the points given.<br><br> (2, 2) and (5, 5)
mario62 [17]
Distance between two points, d, is given by
d= \sqrt{ ( x_{2} - x_{1}) ^{2} + (y_{2} - y_{1}) ^{2} }&#10;
where: (x1, y1) = (2, 2) and (x2, y2) = (5, 5)
d= &#10;\sqrt{ ( 5 - 2) ^{2} + (5 - 2) ^{2} } \\ d= \sqrt{ (3)^{2} + 3^{2} }  &#10;\\ d= \sqrt{9+9}  \\ d= \sqrt{18}  \\ d=3\sqrt{2} \ units

a city that has an elevation of 15 meters is closer to sea level than a city with an elevation of -10 true or false? explain you
12345 [234]

Answer:

False

Step-by-step explanation:

At sea level, elevation is 0. This means that we can portray sea level as being the midpoint of distances below sea level and distances above sea level.

Thus, a distance of 1 m below sea level = - 1 is equivalent to a distance of 1 m above sea level albeit in opposite directions.

Hence, an elevation of 15m above sea level is greater in distance Than an elevation of - 10 m below sea level because the absolute value of 15 is greater than the absolute value of 10.

|15 - 0|= 15

|-10 - 0| = 10

Hence, elevation of - 10 below Sea level is closer to sea level than elevation of 15 above sea level

Jamar's teacher told him that one of the reasons he gave on the proof below was incorrect. Which reason did he make the mistake
Kamila [148]

Answer:

Reason given in step 2. is incorrect. It should read; "Distributive Property."

Step-by-step explanation:

The reason given to go from :

2 (3x +4) = 56  to 6x + 8 = 56

is NOT "Multiplication Property of Equality" because one is not multiplying both sides of the equality by a number. The property that is being used is the Distributive Property on the left side of the equation in order to remove the grouping symbols (parenthesis) performing the implied multiplication of the external factor times each term of the binomial in parenthesis.

A city's population is 12,000 and grows at 2.6% rate. What will the population be after 25 years? A city's population is 230,000
Levart [38]

Answer:

The 12000 City would become 22,986 people, while the 230,000 city would become a population of 124,223.

Step-by-step explanation:

1st Part:

=12000⋅(0.026000000000000002⋅25)

=12000(2.718281828459045)(0.65)

=22986

2nd Part:

=230000⋅(−0.044000000000000004⋅14)

=230000(2.718281828459045)(−0.616)

=124223
