The temperature in Chicago is dropping at a rate of 1 degree every 4 hours when it was 10 degrees outside. The temperature in Pittsburgh was increasing at a rate of 3 degrees every 4 hours when it was 2 degrees outside. How long will it take the two cities to reach the same temperature? What is the temperature at that time?
Answers
Answer:
Chicago after 8 hrs it dropped to 8 degrees and at pittsburgh after 8hrs passed it reached to 8degrees outside
so after 8hrs the cities reached the same temperature which is 8degrees
Step-by-step explanation:
10-1=9 then 9-1=8
1= each degree that dropped every 4 hours

If an integer from 3 through 14 is chosen at random, what is the
probability that the number chosen is NOT prime?
Answers
Answer:[tex]\frac{7}{12}[/tex]
Step-by-step explanation:
Given
There are integer between 3 and 14 available to be chosen (total 12 integers)
Prime integers among them
3,5,7,11,13 i.e. total of 5 prime integers
So the probability that the number chosen is not Prime
[tex]=1-P\text{(no is prime)}[/tex]
[tex]=1-\frac{5}{12}[/tex]
[tex]=\frac{12-5}{12}[/tex]
[tex]=\frac{7}{12}[/tex]
Tell whether the ordered pair is a solution of the system of equations.

y = 4x– 1
1. No, (2,1) is a solution for y = 4x – 1 but not for 2x + y = 5.
2. Yes, (2,1) is a solution for both equations
3. No, (2,1) is a solution for 2x + y = 5 but not for y = 4x - 1
Answers
Answer:
2x + y = 5
y = 4x – 1
Substitute (2, 1) into system, then:
2x + y = 5 => 2 x 2 + 1 = 5 => 5 = 5 (satisfied)
y = 4x– 1 => 4 x 2 - 1 = 1 => -7 = 1 (not satisfied)
=> Option 3 is correct.

Answers
Missing part of the question
- 10 in, by 12 in. by 24 in.
- 12 in. by 15 in. by 18-in.
- 10 in. by 16 in. by 20 in.
- 12 in. by 12 in. by 20 in.
Answer:
The possible dimensions of the container are
- 10 in, by 12 in. by 24 in
- 12 in. by 12 in. by 20 in
Step-by-step explanation:
Given
Volume of the container = 2,880 cubic inches
Required
Possible dimensions of the container
To solve this question, the following assumption has to be made;
It'll be assumed that the container is a rectangular
To calculate the volume of a rectangular figure, we simply multiply the dimensions of the figure,
This implies that; we'll test each of the given options.
Which ever gives 2,880 is the right answer.
- 10 in, by 12 in. by 24 in.
[tex]Volume = 10 in * 12 in * 24 in[/tex]
[tex]Volume = 2,880[/tex] cubic inches
- 12 in. by 15 in. by 18-in.
[tex]Volume = 12 in * 15 in * 18 in[/tex]
[tex]Volume = 3,240[/tex] cubic inches
- 10 in. by 16 in. by 20 in.
[tex]Volume = 10 in * 16 in * 20 in[/tex]
[tex]Volume = 3,200[/tex] cubic inches
- 12 in. by 12 in. by 20 in.
[tex]Volume = 12 in * 12 in * 20 in[/tex]
[tex]Volume = 2,880[/tex] cubic inches
From the calculation above, only option A and D gives 2,880;
Hence, the possible dimensions of the container are
- 10 in, by 12 in. by 24 in
- 12 in. by 12 in. by 20 in
Given a volume of 2,880 cubic inches, one possible set of dimensions for a shipping container could be length = 24 inches, width = 15 inches, and height = 8 inches.
The volume of a rectangular container can be calculated by multiplying its length, width, and height. Given the volume of 2,880 cubic inches, we are looking for three numbers (dimensions) that, when multiplied together, equal 2,880.
One possible set of dimensions could be length = 24 inches, width = 15 inches, and height = 8 inches. Multiplying these dimensions together: 24 inches × 15 inches × 8 inches = 2,880 cubic inches, which matches the given volume of the container.
Below is the graph of a trigonometric function. It has a maximum point at (-5pi/4,6.7) and an amplitude
of 4.1. What is the midline of the function? Y=____
Answers
We have been given that the maximum point at the graph of a trigonometric function is [tex](-\frac{5\pi}{4},6.7)[/tex] and amplitude of the function is 4.1. We are asked to find the mid-line of the given function.
We will use mid-line formula to solve our given problem.
[tex]\text{Mid-line value}=\text{Maximum value}-\text{Amplitude}[/tex]
Upon substituting our given values in above formula, we will get:
[tex]\text{Mid-line value}=6.7-4.1[/tex]
[tex]\text{Mid-line value}=2.6[/tex]
Therefore, the mid-line of the given function would be [tex]y=2.6[/tex].
6(a+3)=2a+30 what is the answer
Answers
Answer:
a = 3
Step-by-step explanation:
6(a+3)=2a+30
Distribute
6a + 18 = 2a+30
Subtract 2a from each side
6a + 18 -2a= 2a+30-2a
4a +18 =30
Subtract 18 from each side
4a+18-18 = 30-18
4a = 12
Divide each side by 4
4a/4 = 12/4
a = 3
What number would you add to both sides of x - 20x = 5 to complete the square?
Answers
Answer:
100
Step-by-step explanation:
If you add 100 to both sides, you get "x^2-20x+100," which simplifies to (x-10)^2
Write an equation in slope-intercept form that goes through the points (-3, -4) and (3,4).
Answers
Answer:
Y = 4/3x + 0
Step-by-step explanation:
(-3,-4) and (3,4) can be plugged in to rise over run.
y 4 -(-4) = 8
x 3 - (-3) = 6
8/6 = 4/3
Plug into slope intercept form
4 = 4/3(3) + b
4 = 12/3 +b
4 = 4 +b
Subtract from both sides
0 = b
Y = 4/3x + 0
The equation in slope intercept form that goes through the points (-3,-4) and (3,4) is [tex]y=\frac{8}{6}x[/tex]
What is Slope of the line?The slope of a line gives the measure of its steepness and direction.
What is the Slope intercept form?The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
Given,
Slope of the line passing through the points (-3,-4) and (3,4)
Slope of the line m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}=\frac{4+4}{3+3}=\frac{8}{6}[/tex]
Therefore slope of the line is [tex]\frac{8}{6}[/tex]
Find the y intercept using the slope and the point (-3,-4)
y=mx + b
-4 = [tex]\frac{8}{6}[/tex]×-3 + b
-4 =-4+b
b=-4+4 =0
Then,
The equation in slope intercept form is
y = mx + b
y = [tex]\frac{8}{6}[/tex]x + 0
[tex]y=\frac{8}{6}x[/tex]
Hence, the equation in slope intercept form that goes through the points (-3,-4) and (3,4) is [tex]y=\frac{8}{6}x[/tex]

V=lwh
V=8×12×6=576 ft³
Answer: V=576 ft³
The volume of the prism is calculated by multiplying the length, width, and height, resulting in 576 cubic feet.
To calculate the volume of the prism, we have to use the formula for the volume of a rectangular prism, which is length times width times height. Given the dimensions of the prism as 12 feet in length, 6 feet in width, and 8 feet in height, the volume is calculated as follows:
Multiply the length by the width: 12 ft times 6 ft = 72 ft².Multiply the result by the height: 72 ft² times 8 ft = 576 ft³.Therefore, the volume of the prism is 576 cubic feet (ft³).
