Answer:
y=10x-26
Step-by-step explanation:
1.find the slope
m=y2-y1/x2-x1
m=-6-4/2-3
m=-10/-1
m=10
2.y-y1=m(x-x1)

Answer:
The answer is "7.036".
Step-by-step explanation:
Throughout the question by Increasing the number of standard deviations by 100 if you compose its issue as a fracture. In each cycle these were multiplied by 100, all numbers were certain ones. [tex]\frac{436.8}{62.08}[/tex] was its sum of [tex]\frac{43,680}{6,208}[/tex].
Following are the calculation to this question:
[tex]= \frac{436.8 \times 100}{62.08 \times 100}\\\\ = \frac{43680}{6208}\\\\=7.036[/tex]
An engineering student is studying the effects of cryogenic treatments on a particular material. The treatment involves cooling the material with specific applications of liquid nitrogen.
Answer:
The answer is "choice 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.
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]
Five busses are needed to transport 300 students. How many students can 7 busses transport?
Answer:
420 students
Step-by-step explanation: I first did 300/5 which got me 60, meaning that one bus could transport 60 students. Then you do 60*7 (60 is how many students on each bus, and 7 is how many buses there are) and get 420 students on 7 buses.

When Shawn cleaned his room he found that the ratio of clean clothes to dirty clothes was 3 to 5 if 46 articles of clothing were discovered how many were clean
Answer:
17.25
Step-by-step explanation:
Ratio of clean clothes to dirty clothes = 3 : 5
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
= 3/8 × 46
= 0.375 × 46
= 17.25

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.
Hope this helped!

What is the inverse operation do use to solve for t?
t - 19=2
We use addition, or rather the addition property of equality.
t-19+19=2+19
t=21
:D
Step-by-step explanation:
Addition is the inverse operation.
inverses:
addition/subtraction
multiplication/ division
If you need to solve for t:
t-19=2
add 19 to both sides to isolate the variable (t)
t=21

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
In 2000, 36 children attended a summer day camp. Attendance has increased by 12% per year since then.
Hence, Number of campers attended summer day camp in 2006 is,
⇒ 36 (1 + 12%)⁶
⇒ 36 (1+ 0.12)⁶
⇒ 36 (1.12)⁶
⇒ 36 × 1.97
⇒ 71
Thus, Number of campers attended summer day camp in 2006 is, 71

Work out the
volume of the
greenhouse.
(nearest m3)
Mark it
9514 1404 393
Answer:
155.52 m³
Step-by-step explanation:
The volume will be the product of the end area and the length of the greenhouse.
The end area consists of 4 triangles and 6 rectangles. We can do a little manipulation of the shapes to simplify the area calculation a bit.
We can divide half of the greenhouse face along its vertical lines to make two trapezoids. Their "bases" will be the lengths of the vertical lines, and their heights will be the dimensions 1.8 m and 0.6 m. Since there are two of each, we can find the end area to be ...
A = 2(1/2)(b1 +b2)(h1) +2(1/2)(b2 +b3)(h2)
A = (3.3 +2.7)(1.8) +(2.7 +0.9)(0.6) = 10.8 +2.16 = 12.96 . . . square meters
__
The volume is then ...
V = Bh
V = (12.96 m²)(12 m) = 155.52 m³ . . . . greenhouse volume

Answer: x^2+29x+39
You would first have to set up an equation, which would be ((2x+9)⋅(x+6))-((x-5)⋅(x-3)) to find the area of both rectangles.
Then you can simplify it, which gives us 2x^2+21x+54-(x^2-8x+15)
Then simplify it even more which gives us 2x^2+21x+54-x^2+8x-15
Then we can get our answer: x^2+29x+39
