Answer:
55.10minStep-by-step explanation:
This problem is on the mensuration of flat shapes.
given that the initial radius before Cody alerted the fire department is
10 ft
Then we can calculate the area of the fire as
Area= πr^2
Area=3.142*(10)^2
Area=3.142*100
Area=314.2ft^2
Also, given that the area of the circular fire has grown to 45401 square feet
let us solve for the radius first, then we can calculate the time taken since the radius was increasing by 2 ft/min
let the radius of the large fire be R
45401=πR^2
R^2=45401/3.142
R^2=14449.714
square both sides we have
R=√14449.714
R=120.2ft
The difference between the radius of the initial fire and the large fire is
R-r=120.2-10
=110.2ft
Hence the time taken can be calculated as
time= 110.2/2
time=55.10min

Step-by-step explanation:
· Josh Duchene worked at three jobs in three weeks. In the first week, he earned $360. In the next week, he
was paid $345. In the third week, he was paid $315. What average pay per week did Josh earn for these
three weeks?
The average pay per week Josh earned for three weeks is $340.
What is an average?The term average is the sum of all the numbers divided by the total number of values in the set.
Now it is given that,
Pay received in first week = $360
Pay received in second week = $345
Pay received in third week = $315
So,
Total money earned in three weeks = $360+$345+$315
= $1,020
Now number of weeks = 3
therefore, average pay per week = Total money earned in three weeks/number of weeks
⇒ average pay per week = $1020/3
⇒ average pay per week = $340
Thus, the average pay per week Josh earned for three weeks is $340.

Answer:
y=3x+18
Step-by-step explanation:
Since slope-intercept form is y=mx+b, we first need to find the slope.
m=y2-y1/x2-x1
m=0-(-9)/-6-(-9)
m=9/3=3
Next we need to find b, or the y-intercept
to do that we plug in numbers to what we already have.
y=3x+b
0=-18+b
b=18
Now we put it all together.

Can someone pls answer these questions for me I’m stuck
Answer:
a) The triangles are similar, and the ratio of the similar sides are both equal to 1:3. b) the scale factor from triangle abc to def is 3 because if you divide the longer corresponding side length from triangle def by the side of triangle abc, you will get 3. c) x is equal to 7.5 cm. Using the scale factor, you can just multiply 3 by 2.5.
Step-by-step explanation:
a) If you look at the two triangles, you can see that they look similar. Side AB looks similar to side DE, and the side lengths are 1 and 3. Therefore, the scale will be 1:3. b) If you divide the longer corresponding side length from triangle def by the side of triangle abc, you will get 3. c) x is equal to 7.5 cm because the scale factor is 3, which means you have to multiply the smaller side by 3.

HELP! will mark branniest answer if right!
Answer:
64 i think
Simple explanation:
find the missing angle of the triangle with two given angles:
add 36 and 84 to get 120
subtract 120 from 180 and you will get 60
subtract 60 from 90 to find one of the angles in the other triangle
so now you have that the other triangle has an angle of 86 and another angle of 30
add 86 and 30 to get 116
subtract 116 from 180 to get the "? angle"
you should get 64
Another possible explanation:
extend the line that contains the degrees 36 and 84
this will make a third, smaller triangle
this triangle has two measure that are easy to find and that is 96 and 54
when you add those together, you get 150
subtract 150 from 180 to get 30
30 degrees is the measure of the smaller angle at the 90 degrees symbol
now add 30 and 86 together to get 116
subtract that from 180 to get 64

Answer:
A.The slope is 2 and the y-intercept is −6.
Step-by-step explanation:
got it right on the quiz. :)
(hop this helps)
The slope of the line represented by the above equation is:
".2 and the y-intercept is −6." (Option A)
The slope of any line, ray, or line segment in analytic geometry is the ratio of the perpendicular to horizontal distance between any two points on it.
Hence it is correct to state that the slope of the line represented by the above equation [f(t)=2t−6] is: ".2 and the y-intercept is −6."

Find the measure of the exterior angle.
Answer:
1) 128°
2) 126°
3) 108°
Question one:The square in the corner means 90°. If you add the interior angles of any triangle together, you get 180. in this case, x is in exterior angle, so you subtract it from 180 to get the interior angle.
38 + 90 + (180-x) = 180
38 + 90 + 180 - x = 180
38 + 90 + 180 - 180 - x = 0
38 + 90 + 180 - 180 = x
128 = x
Question two:
again, adding all the interior angles makes 180°. use this to make the equation.
3x + (5x-6) + 90 = 180
3x + 5x - 6 = 90
8x = 96
x = 12.
x isn't the answer the question wants, however. if you look at the drawing, the angle that's supplementary to 5x-6 is the exterior angle. so,
180 - (5x-6) = the answer
180 - 5x + 6 = the answer
substitute x for 12
180 - 60 + 6 = the answer
126 = x
Question three
again, adding all the interior angles together makes 180°.
(a + 10) + 44 + (180-2a) = 180
a + 10 + 44 + 180 - 2a = 180
-a + 234 = 180
234 - 180 = a
54 = a
however, the question is looking for the exterior angle, not a. in this case, the exterior angle is 2a, so just multiply 54 by 2.
x = 108
