Giving brainly help find Find m∠H.

Answers

8X -2 + 5X + 26 =180

13X +24 = 180

13X = 180-24
13x = 156

X = 156/13

X= 12

Now replacing the value of 12 in 5X +26


5* 12 + 26 = 60 + 26 = 86

The required measure of the angle m∠H is given as 94°.

What are the angle?

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,
For trapezoid, the sum of the adjacent angle is 180°
m∠H + m∠G = 180
5x + 26 + 8x - 2 = 180
x = 12

Now,
m∠H = 8x - 2
        = 8 (12) - 2
        = 94°

Thus, the required measure of the angle m∠H is given as 94°.

Miguel is working at the county fair. On​ Friday, he works at the concession stand. On​ Saturday, he works at the balloon dart booth. At the concession​ stand, Miguel sells 7 soft pretzels for every 2 candied apples. How much profit will the concession stand make if it sells 161 soft​ pretzels? Explain.

Answers

Answer:

$362.25

Step-by-step explanation:

Profit made per product :

Soft pretzel = $5.25 - $3.50 = $1.75

Candied apple = $3.50 - $1.75 = $1.75

For every 2 candied apple sold, 7 soft pretzel is sold :

If 161 sold pretzel is sold, the number of candied apple sold will be :

(161 / 7) * 2

23 *. 2 = 46 candied apple was sold

Profit made on product sold :

Soft pretzel = $1.75 * 161 = $281.75

Candied apple = $1.75 * 46 = $80.5

$(80.5 + 281.75) = $362.25

states he can buy a number of

plums that cost exactly $3.80.

Complete Parts A and B to show

Sergio's statement is false.



PLEASE HELP QUICKLY NO LINKSS!

Answers

Answer:

Sergio's statement is false

Step-by-step explanation:

Cost of one pound of plum = 1.60

Total quantity of plum bought = 1

Weight of each plum = 1/4 pound

If he buys plum of $ 3.80 at the rate of $1.60 per pound, he purchases 2.375 pounds of plum

Weight of one plum = 1/4 pound, thus total number of plum purchased = 9.5

Since 0.5 pound of plum means half plum which is not possible to buy

Hence Sergio's statement is false

George has a spinner with three equal sections colored orange, blue, and white. He spins the spinner 100 times. What is the experimental probability of landing on the orange section?

Answers

Answer:

1/3

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Experimental probability is based on the result of an experiment that has been carried out multiples times

probability of landing on the orange section = proportion of the orange section / total proportions of all the colours

Answer:

You got it! B. x ≤ -7 or x ≥ 2

Step-by-step explanation:

In inequalities, a filled dot means "also including," so the value at which the filled dot is placed is also included in the inequality (hence the "or equal to"). In this case, both red dots (at -7 and 2) are filled, so both values are included in the inequality.

The red portions are part of the inequality. Looking at the arrow going from -7 and pointing to the left, we can tell that that value and the ones smaller than -7* are included, so it would be x ≤ -7.

Looking at the arrow pointing from 2 to the right, it includes 2 and all the numbers to the right of it, so the inequality would be x ≥ 2.

So, the final answer is B. x ≤ -7 or x ≥ 2.

Step-by-step explanation:

x + y = 4a + 7

x - y = 2a + 5

In both equations, make x the subject of the formula

x = 4a + 7 - y equation 1  

x = 2a + 5 + y equation 2

Subtract equation 2 from equation 1

2a + 2 -2y
