An artist’s canvas has sides measuring 3x – 3 and 4x + 1 inches.
What is the area of the canvas? Show all work.
The artist laid the canvas flat on the floor and poured some paint in the center. The paint flows at a rate of r(t) = 4t where t represents time in minutes and r represents how far the paint is spreading on the canvas. The area of the paint can be expressed as A[r(t)]= πr². What is the area of the circle created by the paint?
If the artist wants the circle to be at least 1300 in², will it be that large in 5 minutes? Support your answer with your work.
Step-by-step explanation:
Finding the area of the canvas:
The canvas has sides measuring 3x - 3 and 4x + 1 inches. To find the area, we multiply the lengths of the sides. So, the area of the canvas is given by:
Area = (3x - 3) * (4x + 1)
= 12x^2 + x - 3
Therefore, the correct equation for the area of the canvas is A = 12x^2 + x - 3.
Finding the area of the circle created by the paint:
The rate at which the paint is spreading on the canvas is given by the function r(t) = 4t, where t represents time in minutes and r represents how far the paint has spread. The area of the circle created by the paint can be expressed as A[r(t)] = πr^2, where r(t) is the distance the paint has spread at time t.
Substituting the value of r(t) = 4t into the formula, we get:
A[r(t)] = π(4t)^2
= 16πt^2
Therefore, the area of the circle created by the paint is 16πt^2.
Determining if the circle will be at least 1300 in² in 5 minutes:
To check if the area of the circle will be at least 1300 in² in 5 minutes, we substitute t = 5 into the equation for the area:
A[r(5)] = 16π(5)^2
= 400π
Approximating the value of 400π, we get approximately, 1256.64.
Since 1256.64 is less than 1300, we can conclude that the area of the circle created by the paint after 5 minutes will not be at least 1300 in².

PLS HELP ! Solve the addition equation by finding a common multiple. one half + two thirds + four sixths equals ___
Answer: 1/2 + 2/3 + 4 /6 = 11/6
Step-by-step explanation:
1/2 + 2/3 + 4 /6
We need to find a common multiple, for the denominator. Let us choose 6, so we do not have to deal with large numbers.
Note that we do not change 4/6, since it already has a denominator of 6.
==> 3/6 + 4/6 + 4/6
Add;
==> 11/6
3/6 + 4/6 + 4/6 equal to 11/6

If you spun the spinner 1 time, what is the probability of landing on either a white piece or a gray?
the circle in the picture has 3 gray and 5 white
there are 9 pieces in total
Answer:
\(\frac{8}{9}\)
Step-by-step explanation:
So, there are 8 pieces with color and 1 piece without the wanted color.
The equation for finding the probability is: \(\frac{sum of terms }{number of terms }\)
Therefore: 3 + 5 = 8 and 9 pieces in total
so the correct answer should be 8/9
the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

The cost of a trail mix at the grocery store is normally $12 per pound but now the price has increased by 30%. What is the price per pound of trail mix now that the price has increased?
Answer:
15.6
Step-by-step explanation:
The price of trail mix has increased by $12 * 30/100 = $<<12*30/100=3.6>>3.6.
So the price per pound of trail mix now is $12 + $3.6 = $<<12+3.6=15.6>>15.6.
The required new price of the trail mix is $15.6 .
What is percentage?Percentage is a measurement to find value of given number out of hundred.
Given that,
The normal cost of trail mix at the grocery store = $12 per pound.
Als0, the price of the trail mix increased by 30%.
To find the price of trail mix after increasing the price,
Use percentage property,
Let the initial price was 100 %
So after increasing 30%, the new price becomes 130%.
The new price = 12 x 130% = 12 x 130 / 100 = 1560/100 = 15.6
The increased price of the trail mix is $15.6.

Find the measures of the supplementary angles that satisfy each case. m∠1:m∠2=5:4
Answer:
100 and 80 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees. Here we are to find two such angles that are in the ratio 5:4. To do this, we set up and solve the following equation:
5x + 4x = 180, or
9x = 180, or
x = 20.
Then one angle is 5(20) and the other is 4(20), or 100 and 80.
Note that these two angles add up to 180 degrees, as they must.
The two supplementary angles are 100 and 80 degrees.
Answer:
I apologize for the confusion caused. Let's go through the problem again to determine the correct answer.
We have a police helicopter flying at 120 mph at an altitude of 1.5 miles above a highway. The radar detects an oncoming car at a distance of exactly 3 miles from the helicopter, and this distance is decreasing at a rate of 190 mph.
To find the speed of the car, we need to consider the relative motion between the car and the helicopter. From the perspective of the helicopter, the car's speed is the sum of its own speed and the rate at which the distance is decreasing.
Let's denote the speed of the car as "v_car" and the speed of the helicopter as "v_helicopter." The relative speed between the car and the helicopter is the difference between the two speeds, given by:
Relative speed = v_car - v_helicopter
Since the distance between the car and the helicopter is decreasing at a rate of 190 mph, the relative speed is -190 mph (negative because the car is approaching the helicopter).
However, since we want to find the speed of the car, we need to consider the magnitude of the relative speed. Taking the absolute value, we have:
|Relative speed| = |v_car - v_helicopter| = |-190|
Now, let's solve for the speed of the car:
|v_car - 120| = 190
We can solve this equation by considering two cases:
Case 1: v_car - 120 = 190
v_car = 190 + 120
v_car = 310 mph
Case 2: -(v_car - 120) = 190
-v_car + 120 = 190
v_car = 120 - 190
v_car = -70 mph
Since speed cannot be negative, we discard Case 2.
Therefore, the correct answer is that the speed of the car, as detected by the radar, is 310 mph.
THIS QUESTION ANSWERLet's assume that the measure of angle 1 is represented by "x" and the measure of angle 2 is represented by "y". We are given that the ratio of the measures of angle 1 to angle 2 is 5:4. This can be expressed as:
x:y = 5:4
Since the angles are supplementary, the sum of their measures is 180 degrees:
x + y = 180
To solve this system of equations, we can use the ratio given to express one variable in terms of the other. Let's express "x" in terms of "y":
x = (5/4) * y
Substituting this expression for "x" into the second equation:
(5/4) * y + y = 180
Multiplying through by 4 to eliminate the fraction:
5y + 4y = 720
9y = 720
Dividing both sides by 9:
y = 80
Substituting the value of "y" back into the expression for "x":
x = (5/4) * 80
x = 100
Therefore, the measures of the supplementary angles that satisfy the given ratio are angle 1 with a measure of 100 degrees and angle 2 with a measure of 80 degrees.

You can use A as a different variable by simply assigning a value to it, like any other variable
What is a variable?A variable is a symbol used to denote a mathematical object in mathematics. Any number, vector, matrix, function, function argument, set, or set element can be represented by a variable.
An amount that can fluctuate depending on the mathematical issue is referred to as a variable. The generic letters x, y, and z are frequently employed in mathematical expressions and equations. A variable is, in other words, a symbol denoting a number whose value is unknown.
You can use A as a different variable by simply assigning a value to it, like any other variable. For example, you could write "A = -6" to assign the value of negative 6 to A. It's important to remember that A is now a distinct variable from X, Y, and K, and should be treated as such in your code or equations.
