What you do is you mulitply 4 times 265 which is 1060! So the exact answer is not reasonable!

Reagan spends 26% of her weekly allowance on 2 banana splits. Banana splits cost $3.25 each. How much does Reagen recieve for he

Kruka [31]

So lets go step by step, first lets see how much Reagan spent, that is 2 banana splits, $3.25 each, that is:
total spent = 2*3.25 = 6.50
So Reagan spent $6.50 of her weekly allowance, and the problem says that $6.50 represents 26% of her weekly allowance, the question is to find out how much represents the 100% of her weekly allowance.
We can solve this using a rule of three, simple, with direct proportion:
26% -----> $6.50
100% ----> x
x = (100)(6.50)/26 = 650/26
x = 25
therefore Reagan's weekly allowance is $25

11th grade geometry:

Aliun [14]

Answer:

<em>The perimeter is 72 units and the area is 149 square units.</em>

Step-by-step explanation:

$\triangle SBA$ has coordinates $S(15,-8),B(-2,21)$ and $A(0,0)$

Using the distance formula.........

Length of side $SB = \sqrt{(15+2)^2+(-8-21)^2}= \sqrt{17^2+(-29)^2}= \sqrt{1130}$

Length of side $BA= \sqrt{(-2)^2+(21)^2}= \sqrt{445}$

Length of side $AS =\sqrt{(15)^2+(-8)^2}=\sqrt{289}=17$

So, the perimeter of the triangle will be: $(SB+BA+AS)= \sqrt{1130}+ \sqrt{445}+17 =71.71... \approx 72$ units. <em>(Rounded to the nearest unit)</em>

The height of the triangle for the corresponding base $SB$ is 8.89 units.

<u>Formula for the Area of triangle</u>, $A= \frac{1}{2}(base\times height)$

So, the area of the $\triangle SBA$ will be: $\frac{1}{2}(\sqrt{1130}\times 8.89)= 149.42... \approx 149$ square units. <em>(Rounded to the nearest unit)</em>
