At a carnival booth, customers had to guess how many jelly beans were in a jar. Samantha guessed there were 295 jelly beans. There were actually 250 jelly beans in the jar. What is Samantha’s percent error?

Answers

Samantha’s percent error was 18%

Samantha's percent error is 15.24%.

What is Percent Error?

The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.

Given:

Samantha guessed there were 295 jelly beans.

There were actually 250 jelly beans in the jar.

So, the percent error

= (295- 250) / 295 x 100

= 45 / 295 x 100

= 0.15254 x 100

= 15.24 %

Dalia buys a winter jacket at a used clothing store that costs $30. She lives in Idaho, where the sales tax is 6%.




Write an equation that represents the total cost, c, of any item bought in Idaho whose price is p

Answers

Answer:

c = 0.06p + p

Step-by-step explanation:

hope this helped

An equation that represents the total cost, c, of any item bought in Idaho whose price is p is c = 1.06p.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

Cost of the winter jacket = $30

Sales tax = 6%

Total cost of the winter jacket = 30 + (6% × 30)

                                                   = 30 + 1.8

                                                   = $31.8

If the total cost of any item is c whose price is p,

c = p + (6% × p)

c = p + 0.06p

c = 1.06p

Hence the required equation is c = 1.06p.

Classify Each triangle by its angle and sides.

Answers

Answer:

8. Scalene 9. Isosceles

Step-by-step explanation:

Answer:

8) Acute Scalene

9) Right Isosceles

Step-by-step explanation:

Triangles can be classified in 3 ways based on their angles: acute, obtuse, and right. There are 3 ways to classify based on sides: scalene, isosceles, and equilateral.

Definitions

Acute - a triangle with 3 acute angles (angles under 90 degrees)

Obtuse - a triangle with 1 obtuse angle (angle greater than 90 degrees)

Right - a triangle with 1 right angle (90-degree angle)

Scalene - a triangle with sides of all different lengths

Isosceles - a triangle with 2 equal sides and angles

Equilateral - a triangle with 3 equal sides

Question 8

From the 2 angles we are given, we can tell that all of the angles are different. This must mean that the sides are also different. Since the sides are different, this must be a scalene triangle. Additionally, the missing angle is 100 degrees; thus, it must be an obtuse triangle.

Question 9

The marks on the 2 sides mean that these lines are equal. Therefore, it must be an isosceles triangle. One of the angles is marked with a box. This means that the angle is 90 degrees.  So, it is a right triangle.

Find the difference. On February 6, 1995, in Sioux Falls, South Dakota, the temperature dropped from 48°F to –16°F in a period of 8 hours. What was the average change in temperature per hour? please help

Answers

Answer:

The average change in temperature per hour was -8°F.

Step-by-step explanation:

Using the equation 48-(-16) we know that the temperature dropped by 64°F.

[tex]48-(-16)=64[/tex]

We now know that the temperature dropped by 64°F in a period of 8 hours. Using the equation -64/8 we can find the average change in temperature per hour.

Find the area of a right triangle with a base of 9 feet and a hypotenuse length of 13 feet and a base of 9 feet.(Round to the nearest tenth.)

Answers

Answer:

Step-by-step explanation:

Remark

The plan is to find the third side. It and the 9 foot side form a right angle. The base is given as 9 feet. The third sid will be the altitutude. The formula is Area = 1/2 * Base * third side.

Formulas

c^2 = b^2 + a^2

Area = 1/2 b * a

Givens

c = 13 feet

a = ?

b = 9 feet.

Answer: 42.2 square feet.

Solution

c^2 = b^2 + a^2

13^2 = 9^2 + a^2

169 = 81 + a^2                 Subtract 81 from both sides.

169 - 81 =81 - 81 + a^2    Combine

88 = a^2                          Take the square root of both sides

√a^2=√88

a = 9.381

Area = 1/2 * 9 * 9.381

Area = 42.21

Rounded to the nearest 1/10 Area = 42.2

Kitten:

2 times in the morning and 2 times in the evening = 4 times per day

That means Ariane feeds her kitten 4k grams of food per day.

Dog:

1 time in the morning and 1 time in the evening = 2 times per day

That means Ariane feeds her dog 2d grams of food per day.

Answer:

If you find the total, you have to add the kitten's food per day and the dog's food per day. That is 4k + 2d, which is the same as choice B.

We can break 4k into 2k + 2k. We can also break 2d into d + d. We can write that as 2k + 2k + d + d. That equals the same as choice C, making it a correct choice.

triple the radius:
circumference =

area =

also explain how u did it for brainliest if its right

Answers

Answer: So when you double the radius, the area goes up by 4 times because 2 squared is 4. The area will always go up by the square of how much the radius goes up. By contrast, the circumference will only double -- from 12.56 to 25.12 because you do not square the radius (or diameter) -- you just multiply it by pi.

The swimming pool is open when the high temperature is higher than 20°C. Lainey tried to swim on Monday and Thursday (which was 3 days later). The pool was open on Monday, but it was closed on Thursday. The high temperature was 30°C on Monday, but decreased at a constant rate in the next 3 days. What is the solution set of the inequality? (also please show the inequality to determine the rate of temperature decrease in degrees Celsius per day, x, from Monday to Thursday.)

Answers

Answer: 30° - 3d ≤ 20°

Step-by-step explanation:

Here the constant rate of decreasing the temperature = d degree,

Thus, the total decreasing in three days = 3d degree,

If the temperature on Monday = 30°

Then the temperature n Thursday =  30° - 3d

Since, The swimming pool is open when the high temperature is higher than 20°

⇒ 30° - 3d ≤ 20°

Which is the required inequality to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.

I could be 110 because it’s looks like
Angle next to 140= 180 - 140 = 40 degrees.
Angle next to 110= 180 - 110 = 70 degrees.
Sum of interior angles of a triangle = 180 degrees.
So, 180 - (40 + 70) = 180 - 110
= 70 degrees.
So, angle next to 70= 180 - 70 = 110 degrees.

Next to her, Allen just stared at the floor of the lander muttering, Not me, not me.She glanced at Lily, who Maria had always known to be fearless, but Lily bit her lip and turned away.

You six have lived your entire lives in space, and its a great privilege to be the first of your generation to see a new planet. The others are watching; if youre afraid, theyll be afraid. Cant any of you find the courage to set an example?Maria shifted uncomfortably in her seat and thought of her parents; they had traveled across the galaxy to find their family a new home, with clean air and good soil, and she knew this planet was for them. Ill do it, Captain, she mumbled as she slipped out of her harness and rose out of her seat. Maria couldnt shake the feeling of trepidation as she stood and watched the doors of the lander slide open.A NEW WORLDA burst of air hit Maria in the face. She scrunched up her nose as an unfamiliar assortment of odors hit her nostrils. Some smelled sweet, some disgusting, and some were just strange. There were never strange smells on the ship; everything was always the same there. What was it going to be like to live where things changed? The rest of the children gathered around the opening as she climbed down the ladder, and Maria tried to smile as she met their worried eyes. Then, suddenly, something crunched underneath her boots; she was standing on the surface of the planet, and it felt nothing like the smooth metallic halls that shed known all her life.Without letting go of the ladder, she turned around to look at the world around the lander. The soil was full of shapes and textures; there were some small, grainy pieces, then larger clumps that she could break with the toe of her boot. One piece was hard and smooth, and she let go of the ladder to pick it up. Captain, she called, I think Ive found a rock!The air was moving, and long, thin, green things bowed and danced. Grasses, Maria whispered to herself, remembering the videos in her science lessons. She let go of the ladder and took soft, slow steps and realized her arms and legs felt like they were full of lead. Natural gravity, she whispered to herself. She started to walk a little more quickly, getting used to the new sensation. She was doing what others had previously thought impossibletaking steps on a new world.A creature with gossamer wings landed on her nose, and she crossed her eyes trying to get a good look at it. Something small and furry scurried across her feet as she spun in a slow circle. Inspired, she ran as fast as she could across the foreign soil; shed never seen somewhere so big, and it was thrilling. Suddenly, a deep, low sound echoed around her. Thats the call of a hornbeast, Captain Curran shouted from the bottom of the ladder. Maria glanced back and saw that he was helping her friends take tentative first steps in the new world.
