The La Jolla tide pools are 67.5 miles from the SLMS. A map shows that 2 inches = 15 miles. What distance is SLMS from the tide pools on the map?

Answers

Answer:

25

Step-by-step explanation:

because you have to divide by 15's

Answer:

9 inches.

Step-by-step explanation:

To find out what d (distance) is, make a proportion of the values you know and d. This would be 15/67.5 = 2/d.

¹⁵/₆₇.₅ = 2/d

Variable d cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by d.

d * (¹⁵/₆₇.₅) = 2

Expand 15/67.5   by multiplying both numerator and the denominator by 10.

d * (¹⁵⁰/₆₇₅) = 2

Reduce the fraction ¹⁵⁰/₆₇₅  to lowest terms by extracting and canceling out 75.

d * (²/₉) = 2

Multiply both sides by ⁹/₂, the reciprocal of ²/₉.

d = (2 * 9)/2

Cancel out 2 and 2.

d = 9

The distance between the SLMS from the tide pools on the map is 9 inches.

Answer:

The hike is 4.5 miles

Step-by-step explanation:

We divided 3 by 2 since 3 is 2/3 done

3 ÷ 2 = 1.5

So now we know what 1/3 is; 1.5

So now we multiply 1.5 by 3

1.5 × 3 = 4.5

Thus, the hike is 4.5 miles long

Mr. Sanchez’s class sold fruit pies for $1.65 each and Mr. Kelly’s class sold bottles of fruit juice for $1.36 each. Together, the classes sold 79 items and earned $118.17 for their school.

(a) Write and solve a system of equations that model the problem. Show all your work.

(b) Which class earned more money?

(c) How much more money did that class earn?

Answers

Answer:

Step-by-step explanation:(a)

1.65p+1.36j=118.17 and p+j=79

We can say p=79-j and sub this value in first equation

1.65(79-j)+1.36j=118.17

130.35-1.65j+1.36j=118.17

-0.29=-12.18

j=42, p=79-j, p=79-42=37

(b)

1.65(37)=61.05 and 1.36(42)=57.12

Sanchez class earned more selling pies.

(c)

61.05-57.12=3.93

So Sanchez class made $3.93 more than Kelley class.

Find the slope of the line containing the points ( a , 1/a ) a n d ( b , 1/b )

its sorta hard to do fractions with typing

Answers

Answer:

slope=(y2-y1)/(x2-x1)

=(1/b-1/a)/(b-a)

=((a-b)/ab)/(b-a)

=(a-b)/ab(b-a)

=(a-b)/(-(ab(a-b))

=-1/ab

The  slope of the line containing the points should be considered as the [tex]-1/ab[/tex]

Calculation of the slope of the line;

Since we know that

slope should be

[tex]=(y2-y1)/(x2-x1)\\\\=(1/b-1/a)/(b-a)\\\\=((a-b)/ab)/(b-a)\\\\=(a-b)/ab(b-a)\\\\=(a-b)/(-(ab(a-b))\\\\=-1/ab\\\\[/tex]

Answers

Answer: -9 degrees Fahrenheit

Step-by-step explanation:

Given: Temperature at 6:00 AM = -12 degrees Fahrenheit

Temperature increased each hour = [tex]\dfrac12[/tex] degrees Fahrenheit

Temperature increase in 6 hours = [tex]6\times\dfrac12=3\text{ degrees Fahrenheit}[/tex]

Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours

Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit

Write your response in complete sentences. The Sky Has No Limits, by Roger T. Reynolds The state of NASAs space program has been the subject of much speculation in recent years. Debates have raged among members of Congress, business owners, and the general public. the president has expressed his thoughts on numerous occasions as well. The conversations seem to boil down to one question: Do the benefits of space travel outweigh the cost? A logical look at the question makes the answer quite apparent. NASAs space program is worth preserving at any cost.Put simply, NASA creates jobs. Jobs, in return, help the economy. A single space project can employ hundreds of workers from high level, top security jobs to lower level, yet important role players. Scientists are assigned to solve problems. Engineers are contracted to build prototypes. Truckers are hired to transport materials. Large corporations are paid for contributions, earning profits so they may hire more employees.The work of NASA also pays huge dividends for the environment. Studying Earth from space provides keen insight into many areas. Scientists monitor the ozone layer. They track the effects of global warming. They study patterns of dangerous storms. They test the possibility of space colonies. All of these activities offer hope to our increasingly overcrowded planet. The work of NASA often leads to advances in technology. Solving the mysteries of space creates solutions that help elsewhere. The Jaws of Life save victims in car accidents. The technology came from NASA research. The artificial heart did, as well. The list goes on. Architects, athletes, and autoworkers have benefited from space-related discoveries. NASA has enhanced everything from shoes to food. You likely come into contact with something improved by NASA nearly every day.It is impossible to list all the benefits of a thriving space program. It is equally impossible to predict how many new benefits are within our grasp. To find them, we must keep reaching for the stars.
