The mean will be equal to 30.5 for the dog walker.
What is mean?Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.
The given data is:-
40+50+30+40+15+25+15+20+30+40
Now the mean will be calculated as:-
Mean = (40+50+30+40+15+25+15+20+30+40) / 10
Mean = 305 / 10
Mean = 30.5
Therefore the mean will be equal to 30.5 for the dog walker.

This figure consists of a rectangle and semicircle.
What is the area of this figure?
Use 3.14 for π.
A shape made up of a rectangle of the left and a semicircle on the right. The rectangle has a width of 15 meters and a height of 12 meters.
Enter your answer to the nearest hundredths place in the box.
Question 5 options:
Step-by-step explanation:
l = 12 metres
b = 15 metres
diameter of semicircle = length = 12 m
radius = 12/2 = 6 cm
area of the figure = area of rectangle + area of semi circle
= l × b + πr²
= 12 × 15 + 3.14 × 6²
= 180 + 113.04
= 293.04 m²
The perimeter of the figure is 60.84 meters.
What is a rectangle?A rectangle is a quadrilateral with all four interior angles 90°.
Given that, the width and height of the rectangle are 15 meters and 12 meters respectively.
Note that the diamter o he semicircel is 12 meters.
The radius of the semicircle is:
12/2
= 6 meters
The perimeter of the figure is given by:
15 + 12 + 15 + π(6)
= 42 + 3.14×6

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.)
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.

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?
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 %

Answer:
x=10
Step-by-step explanation:
so your given an angle, 110, and another with an equation, 8x+30, which happens to be vertical to 110 degree angle meaning they are equal, so they both are equal to 110 now how do you solve for x? you simply reverse the equation that x is in, so you subtract 110-30=80, then divide by 8 giving you 10, so x=10.
Answer:
X = 10, because of the second angle's equation. 8x + 30 hints the solution. 110 - 30 is 80, and 80 / 8x In this case, x can be represented as itself is 10

REPEATED REASONING What happens to the circumference and the area of a circle when you double the radius? triple the radius?
double the radius:
circumference =
times larger,
area =
times larger;
triple the radius:
circumference =
times larger,
area =
times larger
also explain how u did it for brainliest if its right
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.
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.)
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

Classify Each triangle by its angle and sides.
Answer:
8. Scalene 9. Isosceles
Step-by-step explanation:
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.

Dylan loves reading. He went to buy books from a bookstore. A school bag and 3 books cost $180. A school bag and 5 books cost $270. How much did each book cost?
School bag _ y
book _ x
system:
y+3x=180
y+5x=270
y=180-3x (and we put that instead of 'y' in the second equation)
(180-3x)+5x=270
180+2x=270
2x=90
x=45
so one book costs $45
and school bag:
y+3×45=180
y+135=180
y=180-135
y=45
Answer:
Each book costed 45$.
Step-by-step explanation:
Let x represent the price of a school bag and y represent the price of a book.
we get the following system of equations:
x+3y=180 (equation 1)
x+5y=270 (equation 2)
using equation 1: x=180-3y
then we substitute x in equation 2 in order to find y:
180-3y+5y=270
180+2y=270
2y=270-180=90
y=90/2=45
and we know that y represents the price of a book, so each book costs 45$.

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
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.

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.
