Only multiplication and division don't change the ratio that made the order pairs in the bigger picture the triangle. Only one is not congruent. I'm about 90% sure I got it correct.
Points are (T,S) = (time, pounds), so you have (3.5, 605) and (10, 2100). Slope is (2100-605) / (10-3.5) = 1495/6.5 = 230. T is the independent variable (like x normally is in linear equations), so that narrows it down to choice A or choice D due to the slope. You can solve for b in y=mx+b or S = mT + b by plugging in one of the points: 2100 = 230(10) + b ===> b = -200. Therefore S = 230T - 200; S(12) = 230*12 - 200 = 2560 lbs [B]
<span>2) (a) Plug in 10 for x </span>
<span>(b) 10000 = 298.94x + 3215.48 </span>
<span>6784.52 = 298.94x </span>
<span>x = 6784.52/298.94 = 22.7 ===> in year 2023</span>
Answer:
3
Step-by-step explanation:
Note that 24 - 10 = 14 don't have black fur
And suppose that these 14 are part of the 17 that don't catch mice
Then.....3 that catch mice must also have black fur....and this is the smallest number that do not catch mice but have black fur
Answer:
AC = 
Step-by-step explanation:
Here we have to draw the figure.
When the rectangle is folded A to C. we get a right triangle.
Here we have to use the Pythagorean theorem to find the side lenght of B.
The sides length of B is AC.
By the Pythagorean theorem, the sum of the squares of the sides is equal to the square of the hypotenuse.
Therefore,
AC^2 = AB^2 + BC^2
Taking the square roots on both sides, we get
AC = 
Answer:
39/18 = 13/6 = 2 1/6
Step-by-step explanation:
factors are 1,2,3,6,9,18
so the reciprocals are
1/1, 1/2, 1/3, 1/6, 1/9, 1/18
when added the sum is 39/18 or 2 1/6
