A scale model of the U.S. National Monument is 10 inches tall. The actual monument is 100 feet tall. Write a scale using the same units on both sides. Example: 1cm = 100cm. (remember, there are 12 inches in 1 foot)

Answers

Answer:

The height of the scale model is 10 inches, and the height of the actual monument is 100 feet. Since there are 12 inches in 1 foot, we can convert the height of the actual monument to inches:

100 feet × 12 inches/foot = 1200 inches

Now we can write the scale as:

1 inch : 120 feet

This means that one inch on the scale model represents 120 feet of the actual monument.

j + 17/4 = 7

HELP QUICK

Answers

Answer:

J = 11/4

Step-by-step explanation:

J + 17/4 = 7

7 as a fraction

7 x 4 = 28

28/4

J + 17/4 = 28/4
J + (17/4 - 17/4) = (28/4 - 17/4)

J = 11/4

Answer:

j = 11/4

Step-by-step explanation:

For quick answer just in your head multiply 4 by 7, which is 28. Then subtract 17 since that’s the given, which you will get 11. So j = 11/4. Hope this somewhat makes sense.

To solve for the value of j, we need to isolate j on one side of the equation.

First, we can simplify the left side of the equation by multiplying both sides by 4 to get rid of the fraction:

j + 17/4 = 74(j + 17/4) = 4(7)

4j + 17 = 28

Next, we can isolate j by subtracting 17 from both sides:

4j + 17 - 17 = 28 - 174

j = 11Finally, we can solve for j by dividing both sides by 4:

j = 11/4

Therefore, the value of j that satisfies the equation is j = 11/4.


we can check whether j = 11/4 is the correct solution by substituting it into the original equation and seeing if it is true.

j + 17/4 = 7

When we substitute j = 11/4, we get:

(11/4) + 17/4 = 7

Simplifying the left side of the equation, we get:

28/4 = 7

Both sides of the equation simplify to 7, which means that the solution j = 11/4 is correct.

To further verify, we can also add 11/4 and 17/4 to get:

11/4 + 17/4 = 28/4 = 7

Since we obtained the same value for both sides of the equation, we can conclude that the solution j = 11/4 is correct.

A 3939
B 1616

Answers

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

16
2+3+5+9+17+22+31+39=128
128/8=16
