The required expression model for the cost of the ramp is y = 2.20x.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Let the area of the ramp be x and the cost to build the ramp be y,
According to the question,
The material Santiago will use to build the ramp costs $2.20 per square foot.
Total cost = 2.20 × area of the ramp
Substitute the variable in the above expression,
y = 2.20x
The above equation represents the equation model for the cost of ramp y for the x square foot area of the ramp.
Thus, the required expression model for the cost of the ramp is y = 2.20x.

Clean clothes = 3
Dirty clothes = 5
Total ratio = 3 + 5 = 8
Total clothing article = 46
how many were clean
Number of clean clothes = ratio of clean clothes / total ratio × total clothing article

We know that 6z-31+something is going to be equal to 180 degrees, because it is supplementary. But what is that something? We see 67 degrees. Do you think this is a corresponding angle to the something that we need to find? Yes, it is! So we know that 6z-31+67 is equal to 180. So, z is 24. Now, since we know the value of the something (67 degrees because of corresponding angles) we can find yet another pair of supplementary angles. 67+x=180! Kind of neat, huh? So, x is equal to 113.

Please help. I don't know-how
Answer: 4
You would set this up like so:
125 ≤ 29.50 + 19.50x
Subtract 29.50 from both sides.
You should be left with 95.50 ≤ 19.50x
From here, you wanna divide both sides by 19.50 (we do this to isolate the x)
You would get 4.89.
Since Tamesha can't buy half a shirt, you don't wanna round up. So, the answer should be 4.
Step-by-step explanation:
Trust Milky. Milky smart!
Answer:
she can buy 4 shirts
Step-by-step explanation:
maximum that she can spend = $125
dress = $29.50
shirt = $19.50
first, take 29.50 and subtract it from 125
⇒ 125 - 29.50 = $95.50 remaining
then take 95.50 and it divide it by 19.50 to determine how many shirts she can buy
⇒ [tex]\frac{95.50}{19.50}[/tex] = 4.897
⇒ 4 shirts
to solve:
take 4 shirts and multiply it by 19.50
⇒ 4 x 19.50 = $78
then take the product and add 29.50
⇒ 78 + 29.50 = 107.50
take the maximum money and subtract 107.50 from it
⇒ 125 - 107.50 = 17.5
Tamesha would have $17.50 remaining.
The coordinates for three points of a rectangle are (2, 6) (2, 9) and (8, 6). What is the coordinate for the fourth point in the rectangle? The coordinates for the fourth point in the rectangle is
Answer:
(8,9)
Step-by-step explanation:
Given
[tex]A = (2,6)[/tex]
[tex]B = (2,9)[/tex]
[tex]C = (8,6)[/tex]
Required
Determine the 4th point
The coordinate point of a horizontal or a vertical rectangle is given as:
(x1,y1), (x2,y2), (x3,y3), (x4,y4)
Where:
[tex]x_1 = x_2[/tex] [tex]x_3 = x_4[/tex] [tex]y_1 = y_3[/tex] [tex]y_2 = y_4[/tex]
So, we have:
[tex]A = (2,6)[/tex] --- [tex](x_1.y_1)[/tex]
[tex]B = (2,9)[/tex] ---- [tex](x_2.y_2)[/tex]
[tex]C = (8,6)[/tex] ---- [tex](x_3,y_3)[/tex]
Using the above equations:
[tex]x_3 = x_4[/tex][tex]=8[/tex]
[tex]y_2 = y_4[/tex] [tex]= 9[/tex]
Hence, the coordinate of the 4th point is:
[tex](x_4,y_4) = (8,9)[/tex]

What is the Pythagorean theorem?In the Pythagorean theorem, the sum of the squares of the sides of a right-angled triangle is equal to the square of the longest side i.e, the hypotenuse of the triangle.
z² = x² + y²
The given triangle is a right-angled triangle. This means that we can use the Pythagorean theorem.
∴ y² + 12² = 13²
⇒ y² + 144 = 169
⇒ y² = 169-144
⇒ y² = 25
⇒ y = 5
Therefore, we have solved for the value of y and found that y = 5. The correct answer is option C.

Step-by-step explanation:
Please find the complete question in the attached file.
This is because the temperature in grades Celsius, y, of material could be represented by the previous diagram, in which x is the period, in hours.
It is evident from the study that, the y-intercept is 40 degrees Celsius and thus the temperature difference is 40.
That edge of the top paraboloid is (15-200) so at most -200 ° C at 15 hours the temperature of the material. During 30 hours, the material returns to its initial temperature as the temperature at x = 30 is 40 °C.
