Answer:
an acute an angle
Step-by-step explanation:
the angel of 31 is smaller than 90 so that would make it an acute angle
A 31° angle is an acute angle because it measures less than 90 degrees.
What are Angles?An angle is formed when two straight lines or rays meet at a common endpoint.
We know that a right angle is always equal to 90 degrees.
Any angle less than 90 degrees is an acute angle
Any angle greater than 90 degrees is an obtuse angle.
A 31° angle is an acute angle because it measures less than 90 degrees. An acute angle is any angle that measures between 0 and 90 degrees.
Hence, A 31° angle is an acute angle because it measures less than 90 degrees.

Answer:
89.50 = 7.75 + 27.25p
subtract 7.75 from both sides
89.50 - 7.75 = 27.25p
81.75 = 27.25p
divide both sides by 27.25
p = 81.75 / 27.25
p = 3
Step-by-step explanation:

Answer: p=3
Hence, the Linear Equation in two variables is used to determine the total number of people who go to the park is - y=7.75+27.25p
Step-by-step explanation:
89.50=7.75+27.25p
89.50-7.75+27.25p
81.75=27.25
81.75/27.25

The distance between City A and City B is 2700 miles. On a certain wall map, this distance is represented by 9 inches. The actual distance between City C and City D is 4100 miles. How far apart are they on the same map?
The distance between City C and City D is represented by 13.67 inches on a certain wall map.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Let x inches would be far apart are they on the same map
We can write this as a ratio as
As per the given information,
9 inches : 2700 miles = x inches : 4100 miles
⇒ 9/2700 = x/4100
⇒ x = (4100×9)/2700
⇒ x = 13.67 inches
Therefore, on a certain wall map, the distance between City C and City D is represented by 13.67 inches.

Kathi and Robert Hawn had a pottery stand at the annual Skippack Craft Fair. They sold some of their pottery at the original price of $13.50 each, but later decreased the price of each by $4.00. If they sold all 91 pieces and took in $972.50, find how many they sold at the original price and how many they sold at the reduced price.
The number sold at the original price is 27 and they sold 64 at the reduced price.
How to calculate the value?Let x = number of pieces sold at 13.50
Let y = number of pieces sold at 9.50
The equation will be:
x + y = 91. ..... i
13.50x + 9.50y = 972.50 ..... ii
From equation i x = 91 - y
13.50x + 9.50y = 972.50
13.50(91 - y) + 9.50y = 972.50
1228.50 - 13.50y + 9.50y = 972.50
1228.50 - 4y = 972.50
4y = 1228.50 - 972.50
4y = 256
y = 256/4
y = 64
Since x + y = 91
x = 91 - 64 = 27
Therefore, the number sold at the original price is 27 and they sold 64 at the reduced price.

Write an equation in slope- intercept form for the line described.
parallel to y = -3x + 4, x- intercept at 4
Answer:
y = -3x + 12
Step-by-step explanation:
If two lines are parallel, their slopes are equal, then m = -3
x intercept is 4 then y = 0
y = mx + b
0 = -3(4) + b
b = 12
y = -3x + 12
the inequality always, sometimes, or never true
4x8> 1 + 4(x + 3)
The given inequality is never true which means it has no solutions. If an inequality has no actual solution, then there aren't any numbers that might be used to solve it and make the statement true. An inequality can be made true by substituting any real number into it if the solution to the inequality is all real numbers.
Given the expression is 4x ₋ 8 > 1 ₊ 4(x₊3)
first apply the distributive property.
4x ₋ 8 > 1 ₊ 4x ₊ 12
now combine the like terms.
4x ₋ 8 > 4x ₊ 13
Variables should be moved to the equation's left side.
4x ₋ 4x > 13 ₊ 8
combine like terms.
0 > 13 ₊ 8
calculate the sum.
0>21
This is the solution of inequality which has no solutions.
Hence the inequality of the expression is never true.

4. The average mass of a grain of one type of sand is 7 x 10-4 gram. There are 1,000 grains of the sand in 1 cubic centimeter. What is the mass, in grams, of 1 cubic centimeter of the sand in scientific notation?
The mass, in grams, of 1 cubic centimeter of the sand in scientific notation is 7 x 10^(-1).
What is scientific notation?Scientific notation is a way of writing very large or very small numbers.
Now it is given that,
Average mass of grain = 7 x 10-4 gram
Number of grains in 1 cubic centimeter = 1,000 grains = 10^3 grains
Thus,
Mass of 1 cubic centimeter of the sand = Average mass of grain * Number of grains in 1 cubic centimeter
⇒ Mass of 1 cubic centimeter of the sand = 7 x 10-4 * 10^3 grams
⇒ Mass of 1 cubic centimeter of the sand = 7 x 10^(-4+ 3) grams
⇒ Mass of 1 cubic centimeter of the sand = 7 x 10^(-1) grams
Thus, the mass, in grams, of 1 cubic centimeter of the sand in scientific notation is 7 x 10^(-1).

The Actual area of the dining room is: 252 square feet.
How to Find the Actual Area Using Scale?Given that the area of the house on a blue print = 7 square inches.
Scale of the blue print = 1 inch : 6 feet.
Therefore, we would have the following proportion:
Area on blue print/actual area = square of the scale
7/actual area = 1²/6²
7/actual area = 1/36
Actual area = (7)(36)
Actual area = 252 square feet.

Answer: Actual area (252 square feet).
Explanation:
How to Find the Actual Area Using Scale?
Given that the area of the house on a blueprint = is 7 square inches.
The scale of the blueprint = is 1 inch: 6 feet.
Therefore, we would have the following proportion:
The area on the blueprint/actual area = square of the scale
7/actual area = 1²/6²

Actual area = (7)(36)
Actual area = 252 square feet.

(3x-5) + (x+1) = 180
The value of 'x' for the given expression is calculated as (x = 48).
What is defined as the linear equation in one variable?A linear equation in one variable is an equation that has only one solution.
It is expressed in the form ax+b = 0, where a and b are two integers and x is a variable. The numbers a' and b' are real numbers.'a' and 'b' are both greater than zero.2x+3=8, for example, is a linear equation with a single variable.Now, for the given expression;
(3x-5) + (x+1) = 180
Open the brackets.
3x-5 + x+1 = 180
Add the similar parts;
4x - 4 = 180
Further simplifying;
4x = 180 + 4
4x = 184
x = 184/4

What is the area of a rectangle?
A rectangle is a closed geometric figure with opposite sides equal to each other. The area of this rectangle is given by the product of its length and width.
Calculating the area of a rectangular garden in terms of a function in x
Let us consider a variable x that denotes the length of a rectangular garden
Given perimeter of a rectangular garden is 88 ft with y as the width of a rectangular garden
Perimeter = 2×(length + breadth)
88 = 2(x + y)
44 = x + y
y = 44 - x
Area of a rectangular garden = xy
= x(44 - x)
= 44x - x² sq. ft
Hence, the area of a rectangular garden in terms of a function in x is given by 44x - x² sq. ft.

Answer: 410 possible points
To solve for the possible points in the course, use a proportion and cross multiply.
What is a proportion?
A proportion is two fractions that are equal to each other. For the fractions to be equal, they are proportionate. In our math problem, percentage is proportionate the the number of points.
The fractions represent information you have, and one variable will represent what you are solving for.
GivenYour points = 361
Points to get an 'A' = your points + 8
'A' = 90% of possible points
Find the points needed for an 'A' at 90%Points to get an 'A' = your points + 8
= 361 + 8
= 369
State variableslet x be the amount of possible points
Write a proportionWe know the number of points for 90% is 369 points. Remember that 90% is the same as 90/100.
Keep the information with the same units inside the same fraction. Here, percentage is represented by the first fraction. Points is represented by the second fraction.
[tex]\displaystyle{\frac{90}{100}=\frac{369}{x}}[/tex]
SolveWe can solve using cross multiplication. This is when we multiply each numerator by the denominator from the other fraction.

The function is not differentiable at x
The correct value of m = 6 and b = -9.
The function f(x) is differentiable at x = 3 and we know that if a function is differentiable at some point means that it is continuous at that point also.
Here function is continuous at x = 3 piecewise
m(3) + b = (3)²
3m + b = 9 .....(1)
and function is differentiable at ( x = 3 ) piecewise
d/dx ( m * x + b ) = d/dx (x)² at ( x= 3 )
( m + 0 ) = 2x at ( x = 3 )
m = 2 * 3
m = 6
By placing the value of m in equation (1)
3m + b = 9
3 * 6 + b = 9
18 + b = 9
b = 9 - 18
b = -9
Therefore, the value of m = 6 and b = -9.
