hram777 [196]

You don't say whether you want simple interest or compound interest. I will assume you want the latter.

A = Compound Amount = P(1+0.04)^3
= $34100(1+0.04)^3 = $38357.86 (answer)

A blueprint of a building gives a scale of 1 in. = 8 ft. If the blueprint shows the building sitting on a rectangle with dimensi

katrin [286]

So scale is 1 inch= 8 ft

so, 26 inches = 8×26 = 208 ft
and , 35 inches = 8×35 = 280 ft

so the actual area= 208×280 = 58240 sq ft !

Passing through (-2, 8) and PERPENDICULAR to y = 2x + 5

tangare [24]

Answer:

$y=\frac{-1}{2} x+7$

Step-by-step explanation:

The slope of a perpendicular line will always be the NEGATIVE RECIPROCAL of the slope of the original line.

y=2x+5

Because this equation is organized in slope-intercept form, y=mx+b, we can identify the slope of the original line is 2. The negative reciprocal of 2 is $\frac{-1}{2}$ . Therefore, the slope of the perpendicular line is $\frac{-1}{2}$ . So far, our equation looks like this:

$y=\frac{-1}{2}x+b$

Now, we must solve for b, the y-intercept of this line. To do that, we can plug in the given point (-2,8) and solve for b:

$y=\frac{-1}{2}x+b\\8=\frac{-1}{2}(-2)+b\\8=\frac{2}{2} +b\\8=1+b$

Subtract both sides by 1 to isolate b

$8-1=1+b-1\\7=b$

Therefore, the y-intercept of this line is 7.

After plugging both the slope and the y-intercept into y=mx+b, we get:

$y=\frac{-1}{2} x+7$

I hope this helps!

Gabe is planning on riding the roller coaster 25 times. If he has already ridden 36% of his 25 times, how many times has Gabe al

AVprozaik [17]

If you do 25 x X = 100
It would be x = 4
So we would divide 36% by 4 to get how many times he rode, which is 9
So he already has ridden 9 times.
BRANLIEST? :)

Suppose a charity received a donation of $17.8 million. If this represents 51% of the charity's donated funds, what is the total

Genrish500 [490]

51% = 17.8 / total

total = 17.8 / 0.51

total = 34.9 million dollars

total = 35 million dollars

17 800 000 / 0.51 = 34901960.78

34901960.78 --> 35 000 000
