av <15
what is the answer?
The inequality equation will be 0 < -15 - y. Then the value of the variable y is less than negative 15.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Zero is less than negative fifteen decreased by y, can be written as mathematically
0 < -15 - y
Then solving for y, we have
y < -15

Mark the statements that are true. A. An angle that measures π/4 radians also measures 45°. B. An angle that measures 180° also measures π radians. C. An angle that measures 60° also measures π/3 radians. D. An angle that measures π/3 radians also measures 30°.
Answer:
TRUE: A, B, C
False: D
Step-by-step explanation:
A full circle of 360° has a radian measure of 2π radians. The relationship is proportional, so π radians is 180°.
__
A. An angle that measures π/4 radians also measures 45°. TRUE
45° × π/180° radians = π/4 radians
B. An angle that measures 180° also measures π radians. TRUE
180° × π/180° radians = π radians
C. An angle that measures 60° also measures π/3 radians. TRUE
60° × π/180° radians = π/3 radians
D. An angle that measures π/3 radians also measures 30°. FALSE
30° × π/180° radians = π/6 radians
A van can ferry a maximum of 12 people.By setting up an inequality , find the minimum number of vans that are needed to ferry 80 people.
Answer:
Given a bus can ferry a maximum of 12 people .by setting up an inquality find minimum number of bus that are needed to ferry 80 people
Given a bus can carry a maximum of 12 people. We need to find minimum number of buses to carry 80 people.
Now 12 people can go in 1 bus.
Therefore 1 person can go in 1/12 bus
Now 1 person can go in 1/12 bus
Therefore 80 people can travel in 1/12 x 80
= 6.6
= 7
Therefore minimum buses needed will be 7
Now we can write inequality as 12 x x > = 80
Or x ≥ 80 / 12
or x > = 6.6

An angle has a reference angle of 40° and its terminal side lies in Quadrant III. What are a possible positive measure and a negative measure for the angle?
The positive measure is 220° and the negative measure is -140°.
How to find the measures of the angle?First, we know that the reference angle is 40°, and it lies on the third quadrant.
So these 40° are measured from the negative x-axis (the axis where the quadrant starts).
This means that the angle measured in the standard way (from the positive x-axis) measures:
M = 40° + 90° + 90° = 220°.
To find the negative measure, we remember that any angle A is equivalent to:
B = A + n*360°.
Where n is an integer.
If we take n = -1 for our angle, we get:
M' = 220° + (-1)*360° = -140°.
So the positive measure is 220° and the negative measure is -140°.

Classify the following triangle
Types of Triangles (Angles):
---Acute = all angles are less than 90 degrees
---Right = one angle is equal to 90 degrees
---Obtuse = one angle is greater than 90 degrees
Types of Triangles (Side Lengths):
---Equilateral = all sides are the same length
---Isosceles = two sides are the same length
---Scalene = all sides are different lengths
The following triangle is obtuse and scalene. It has one angle that is greater than 90 degrees and its sides are all different lengths.
Hope this helps!
B. Scalene
E. Obtuse
Step-by-step explanation:Triangles can be classified in 2 different ways. They can be classified based on their sides and angles.
Sides
There are 3 different categories for the sides: scalene, isosceles, and equilateral.
Scalene - these triangles have 3 sides that are all different lengths.Isosceles - Isosceles triangles have 2 congruent sides. This also means that they have 2 congruent angles.Equilateral - These triangles have all equal sides, which also means all the angles are also equal.Angles
Triangles can be classified as acute, obtuse, or right based on their angles.
Acute - Acute triangles only have acute angles. This means there is no angle over 89 degrees.Obtuse - Obtuse triangles have 1 obtuse angle. Obtuse angles are over 90 degrees.Right - Right triangles have 1 right angle. Remember that right angles are exactly 90 degrees.Scalene Obtuse Triangle
The triangle above has no equal sides, so it must be scalene. Additionally, because one of the angles is 132 degrees, it must be an obtuse triangle.

Answer:
5 gallons
Step-by-step explanation:
Unit conversion (given) : 1 gallon = 3.785 liters
Here, we are given 18 liters.
Then, let the value in gallons be x. We can take the values in proportion.
⇒ [tex]\frac{x}{1} = \frac{18}{3.785}[/tex]
⇒ [tex]x = \frac{18}{3.785}[/tex]

A bag contains 8 red marbles, 9 yellow marbles, and 7 green marbles. how many additional red marbles must be added to the 24 marbles already in the bag so that the probability of randomly drawing a red marble is 3/5
Answer:
16 red marbles
Step-by-step explanation:
8 red
9 yellow
7 green
total = 8 + 9 + 7
p(red) = 8/24 = 1/3
Add r number of red marbles to the total.
8 + r red
9 yellow
7 green
total = 8 + r + 9 + 7 = r + 24
p(red) = (8 + r)/(r + 24) = 3/5
Cross multiply.
40 + 5r = 72 + 3r
2r = 32
r = 16
Answer: 16 red marbles
Answer:
16
Step-by-step explanation:
bag red: 8 + x
yellow:9
green 7/24
3/5 = 8+ x/24+ x
5(8 + x) = 3 (24 + x)
40 + 5x
-40 -3x = 72 + 3x
-40 -3x -40 - 30
2x/2 = 32/2 so,x = 16
A TV has a listed price of $841.99 before tax. If the sales tax rate is 9.5%, find the total cost of the TV with sales tax included
Answer:
[tex]9.5 \div 100 \times 841.99 = 79.99 \\ \\ 841.99 + 79.99 \\ 921.98[/tex]
Answer:
$921.98905
Step-by-step explanation:
To find the sales tax amount we need to find 9.5% of 841.99
for this we can use 2 methods:
Method 1-
P%* X= Y
9.5%*841.99= Y
Convert 9.5% to a decimal by removing the percent sign and dividing by 100: 0.095
Substitute 0.095 for 9.5% in the equation: 9.5% * 841.99 = Y becomes 0.095 * 841.99 = Y
Do the math: 0.095 * 841.99 = 79.98905
OR
method 2-
9*841.99
=7998.905
÷100
=79.98905
Now that we know how much the the amount is all we have to do is add the amount with the original price of the tv
$841.99 + $79.97905= $921.98905

A student says that the x-intercept of the graph of × + 2y =5 is the point (0,5). Is the student correct or incorrect? Explain your answer and show your work.
Will give brainliest!!
The student is incorrect, the actual x-intercept is (5, 0).
Is the student correct or incorrect?
Here we have the equation:
x + 2y = 5
The student says that the x-intercept is the point (0, 5).
So if you look at the point you already can see that the student is incorrect, this is because the x-intercept always must have a y-value of 0. (the graph only intercepts the x-axis when y = 0).
So the point (0, 5) can't be an x-intercept.
For the given function:
x +2y = 5
The x-intercept is given by:
x + 2*0 = 5
x = 5
So it is (5 , 0).

The total surface area of the given pyramid is:
A = 39ft²
How to get the surface area of the given figure?
The total surface area will be equal to the sum of the areas of the square and the 4 triangles.
Remember that for a square of side length S, the area is:
A = S².
In this case, S = 3ft, then:
A = (3ft)² = 9ft².
Now, the area of a triangle of base B and height H is:
A = B*H/2.
Here we can see that the triangles have a base of 3ft (the sides of the square) and a height of 5ft, then the area of each triangle is:
A = (3ft)*(5ft)/2 = 7.5 ft²
Then the total area of the figure is:
A = 4*(7.5 ft²) + 9ft² = 39ft²
