Which Equation Can Be Used To Determine The Value Of X?

Answers

Answer 1

Answer:

choice 1) 2x + 40 = 180

Step-by-step explanation:

(x + 10) + (x + 30) = 180

2x+ 40 = 180

Answer 2

Answer:

X+30+x+10=180

combine like terms

2x+40=180

subtract 40 from both sides

2x=140

divide by 2

x=70

but for you it is 2x+40=180

The dot plot shows a random sample of the number of fish caught and released by 30 participants during a two-day fishing derby. Two dot plots show the number of fish caught on days 1 and 2. The dot plot for day 1 has dots as follows: 3 above 1, 6 above 2, 6 above 3, 6 above 4, 6 above 6, and 3 above 6. The dot plot for day 2 has dots as follows: 3 above 1, 3 above 2, 4 above 3, 6 above 4, 7 above 5, and 7 above 6. Use the mean value of each data set to make an inference about the number of fish caught each day. On average, most participants caught and released 5 or more fish. More participants caught 6 fish than any other number. The same participants who caught and released 1 fish the first day caught and released 1 fish the second day. On average, participants caught and released more fish on Day 2.

Sally is at the park standing directly under a kite which is 20 feet overheadSally's dad is flying the kitc and is standing 15 feet from her If both are on level ground, how long is the kite string in feet?

Answers

Answer:

25 feet

Step-by-step explanation:

Given that Sally is at the park standing directly under a kite which is 20 feet overheadSally's dad is flying the kitc and is standing 15 feet from her If both are on level ground, how long is the kite string in feet?

To calculate the length of the kite string, we will apply pythagorean theorem.

Length = sqrt ( 20^2 + 15^2 )

Length = sqrt ( 400 + 225 )

Length = sqrt ( 625 )

Length = 25 feet.

Therefore, the length of the kite string is 25 feet.

If x and y vary inversely and x = 1 when y = 11, find x when y = 5.5.

Answers

Answer:

x = 2.

Step-by-step explanation:

y = k/x

11 = k/1

so k = 11

y = 11/x

When y = 5.5:

5.5 = 11/ x

x = 11/5.5

= 2.

The values of x and y vary inversely, if the value of y is 5.5 then the value of x will be equal to 2.

What is an arithmetic operation?

The four fundamental operations of arithmetic are addition, subtracting, multiplying, and dividing two or more numbers. Included is the study of integers, especially the order of operations, which is essential for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the information provided in the question,

y = k/x

11 = k/1

k = 11

y = 11/x

If y = 5.5,

5.5 = 11/ x

x = 11/5.5

x = 2.

If 12% of the air leaks out of Brian's bicycle tire every day, what percent of the air will be left after 2 days? After a week? Round your percents to 2 decimal places.

Answers

Answer:

77.44%

49.87%

Step-by-step explanation:

If 12% leaks everyday, on the first day 12% would leak, leaving 100 - 125 = 88% of air

on the second day, 12% of 88% would leak = 0.88 x 0.12 = 0.1056

Air left on the second day = 88% - 10.56% = 77.44%

After a week = (100 - 12%)^7 = 49.87%

Two trains leave stations 196 miles apart at the same time and travel toward each other. One train travels at 80 miles per hour while the other travels at 60
miles per hour. How long will it take for the two trains to meet?

Answers

Answer:

The time at which the two trains will meet is 1 hour and 24 minutes

Step-by-step explanation:

The distances between the two trains = 196 miles

The direction of the two trains = Towards each other

The speed of one of the trains = 80 miles per hour

The speed of the other train = 60 miles per hour

Let 't' represent the time at which the two trains meet, we have;

80·t + 60·t = 196

∴ 140·t = 196

t = 196/140 = 7/5

The time at which the two trains will meet, t = 7/5 hours = 1.4 hours = 1 hour, 24 minutes.

Answers

Answer:

m = -10, 14 x = 1, -5

Step-by-step explanation:

m^2 - 4m = 140 (in a parallelogram, opposite angles are congruent)

(1)m^2 - 4m - 140 = 0

Objective: Find two numbers that multiply to -140(1 * -140) and add to -4

Numbers: 10, -14

(m + 10)(m - 14) = 0

m + 10 = 0, m - 14 = 0

m = -10, m = 14

x^2 + 4x = 5 (in a parallelogram, opposite sides are equal)

(1)x^2 + 4x - 5 = 0

Objective: Find two numbers that multiply to -5(1 * -5) and add to 4

Numbers: -1, 5

(x - 1)(x + 5) = 0

x - 1 = 0, x + 5 = 0

x = 1, x = -5
