Answer:
- 8° per hour
Step-by-step explanation:
Given that:
Station A = - 6°
Station B = 2°
Rate of temperature change = x° / hour ; which is the same at both stations
Temperature at station A 3 hours after the recording is the same as the temperature in station B 4 hours after the recording ;
Temperature change in Station A:
-6 + 3x
Temperature change in station B:
2 + 4x
Temperature change in A = temperature change in B
-6 + 3x = 2 + 4x
Collect like terms
3x - 4x = 2 + 6
- x = 8
x = - 8
Hence, the rate of temperature change x in both stations is - 8° per hour

Gabriel lives in a state where the sales tax rate is 6.25%. If Gabriel purchase an item for $60.00, how much sales tax does he need to pay for his purchase?
Answer:
Gabriel needs to have $3.75 for sales tax.
Step-by-step explanation:
A sales tax rate of 6.25% means that 6.25 cents is going to be charged for tax for each dollar you spend. (Because 6.25% of $1.00 is 6.25 cents.)
If he was spending $10, the sales tax would be 62.5 cents (6.25 cents per dollar x 10 dollars). Since he is spending $60 on this item, the equation would be (6.25 cents per dollar x 60 dollars) (6.25 cents x 60 = 375 cents).
And 375 cents equals $3.75.

You are making a salad. The ratio of olives to croutons is 5 : 3. You put 12 croutons in your salad. How many olives do you put in your salad?
Answer:
20
Step-by-step explanation:
12/3 (the number of croutons) = 4
Since 4 is your base number, you would multiply 4 x 5.
20 olives
Answer:
20
Step-by-step explanation:
Ratio of olives : croutons is 5 : 3.
If you put 12 croutons, you put 4 times the amount of croutons in the ratio since 12/3 = 4.
That means you must also put 4 times the number of olives.
4 * 5 = 20

Write an inequality for the graph below
Answer:
y > -1/4x + 4
Step-by-step explanation:
First find the equation of the line itself, which is y = -1/4x + 4, then determine if graph shades above the line or below the line. If it shades above which is true in this case, it will be greater than. If it shades below which does not occur in this case, it will be less than. Because the line is dashed and not solid, it will just be greater than or less than.
Therefore y = -1/4x + 4 → y > -1/4x + 4 [Shades above the line, line is dashed].

Step-by-step explanation:
6 x - 2 (x - 5) = 22
Answer:
x = 2.75
Step-by-step explanation:

6x -2x + 10 = 22
4x + 10 = 22
- 10 - 10
4x = 11

Answer:
[tex]x^{2}[/tex] - x - 24 = 0
a = 1

4(x - 5) = 4x - 20
[tex]x^{2}[/tex] - 5x + 4x - 20 = 4

Ms. Sanchez bought 3 pounds of turkey to make sandwiches for her family. She uses 1/3 of a pound for each sandwich. How many sandwiches can she make?
Answer:
the total number of sandwich required is 9
Step-by-step explanation:
The computation of the number of sandwiches made is as follows:
She bought 3 pounds
And one third of pound she required for each sandwhich
So, the total number of sandwich required is
= 3 ÷ 1 ÷ 3
= 3 × 3
= 9
Hence, the total number of sandwich required is 9

What is a system of equations?A system of equations is a set or collection of two or more equations with the same variables. The common solutions are the intersecting points of the equations. The number of equations and unknowns affects the existence and uniqueness of the solution. A system of equations can be classified similarly to single equations.
Given that, the graph given shows a system of equations,
We know that, the solution of the system of equations, is given by the point where the lines intersect,
So, here the lines intersect, at (3, 2)
Therefore, the x-coordinate is 3
Hence, the x-coordinate of the solution to the system of equations is 3.

Write in y=mx+b form
Answer:
y = -2/3x
Step-by-step explanation:
To write in y=mx+b form, you need the y-intercept (b) and the slope (m).
The y-intercept is the point the line crosses the y-axis. This line crosses the y-axis of (0, 0). This makes the y-intercept equal to 0.
The slope is the rise of the line over the run of the line. Pick two points from the line. It doesn't matter which ones, you will get the right answer regardless.
I picked (0, 0) and (-3, 2). Subtract the x-values from each other, and subtract the y-values from each other.
-3 - 0 = -3 (x)
2 - 0 = 2 (y)
Divide the y by the x to find the slope.
2/-3 = -2/3
Plug in the slope and y-intercept into the equation.
y = mx + b
y = -2/3x + 0
y = -2/3x

The circumference of the base of a right circular cylinder is 252 cm. Find the lateral surface area if the height is 3 m.
Answer:
The lateral surface area is [tex]80,638.4 \ cm^2[/tex]
Step-by-step explanation:
Lateral Surface Area of a Cylinder
It can be computed with the formula:
[tex]\displaystyle A=\pi r^2+2\pi rh[/tex]
Where:
r = radius of the circular base
h = height
The circumference of the base can be calculated as:
[tex]C = 2\pi r[/tex]
We are given the circumference C=252 cm, let's find the radius solving for r:
[tex]\displaystyle r=\frac{C}{2\pi}[/tex]
[tex]\displaystyle r=\frac{252\ cm}{2\pi}[/tex]
r = 40.1 cm
Now we calculate the lateral surface area knowing h=3 m=300 cm:
[tex]\displaystyle A=\pi 40.1^2+2\pi 40.1*300[/tex]
[tex]\boxed{A = 80,638.4 \ cm^2}[/tex]
The lateral surface area is [tex]80,638.4 \ cm^2[/tex]
