An octagon has an area of 55.3 square inches. It is a smaller version of an octagon whose dimensions are 7 times larger. What is the area of the larger octagon?

Answers

9514 1404 393

Answer:

2709.7 square inches

Step-by-step explanation:

If the linear dimensions are a factor of 7 larger, then the area is a factor of 7^2 = 49 larger.

larger area = 49(55.3 in^2) = 2709.7 in^2

Answers

Answer:

1) x: small #; y: large #

4y = 7x

x + y = 22

----------------

-7x + 4y = 0

x + y = 22

---multiply the second equation by -4------

-7x + 4y = 0

-4x - 4y = -88

----solve------

-11x = -88

x = 8

---substitute with any of the equation above i chose the very first one------

4y = 7(8)

4y = 56

y = 14

x = 8; y = 14

2) x = small #; y = large #

y - x = 15

5x = y - 9

----after rearranging, solve-----

-x + y = 15

5x - y = -9

-4x = 6

x = -1.5

--------substitute--------

-(-1.5) + y = 15

1.5 + y = 15

y = 13.5

x = -1.5; y = 13.5

3) x = lemon cream; y = fudge cookie

3x + 2y = 400

2x + 3y = 425

----multiply the first equation by -2, multiply the second equation by 3------

-6x - 4y = -800

6x + 9y = 1275

----solve------

5y = 475

y = 95

--------substitute--------

3x + 2(95) = 400

3x + 190 = 400

3x = 210

x = 70

x = 70; y = 95

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?

please drop an explanation, and equation thanks!

Answers

Ok so we want to cross multiply.
To do this you know 4/9=2$ so now you want to know 1=x$
When you do this you get $5

Answer:

1 kg of baking soda costs $4.50.

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

4/9 kg $2

------------- = --------------

1 kg x

Multiplying both numerators by 9, we get:

4 kg $18

------------ = ---------

1 kg x

Cross-multiplying, we get 4x kg = $18-kg. Solving for x, we get:

$18-kg

x = -------------- = $4.50

4kg

1 kg of baking soda costs $4.50.

Engineers are digging a 3200-foot-long tunnel at a constant rate. After 5 months, the engineers still need to dig 1700 feet to finish the project. How much time does it take to complete the tunnel from start to finish?

Will the engineers have enough time if the project was started in December 2020 and the deadline to finish the project was in August 2021? Please explain your answer for yes or no.

Hint:
y=mx+b (slope-intercept form)
x=time
y=distance
b=3200
Start & Finish: ??
Total length=3200ft
Left over=1700ft after 5 months of digging

help/

Answers

Answer:

Part A answer: 10 2/3 months

Part B answer: No

Step-by-step explanation:

Using what we gathered from the word problem, and the hint, we know that y = distance, x = time, and b = 3200.

3200 is the total number of ft meant for the hole to be dug. If we've been digging for 5 months, and we have 1700 ft yet to be dug, then after 5 months we have dug (3200 - 1700 =) 1500 ft in 5 months.

-1500 ft/5 months = 300 ft/month

-Digging the final 1700 ft will take 5 2/3 months

^ Using this information, we know that the total number of months it takes to dig the entirety of the tunnel is 10 2/3

In the second part of the problem, we're asked to determine whether or not a deadline of August 2021 was enough time to complete the 10 2/3 month-long project if the digging began in December of 2020.

If said project commenced in December 2020, and the deadline was August 2021, then there would be 1, 2, 3, 4, 5, 6, 7, 8... Roughly 8 1/2 months to complete the tunnel. 10 2/3 months is > (greater than) 8 1/2 months. So, no. That start-to-finish deadline would not be enough time.

Good luck!!

Answer:

They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.

In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.
