8 x 2/3 x (-6) x (3/4) x (-1)

ANTONII [103]

Simplify the following:

(-6 (-8)×2×3 x x x x)/(3×4)

(8 x×2 x (-6) x×3 x (-1))/(3×4) = (8 x^4×2 (-6)×3 (-1))/(3×4):

(-6 (-8)×2×3 x^4)/(3×4)

8×2 = 16:

(-6 (-3)16 x^4)/(3×4)

16 (-6) = -96:

(-3-96 x^4)/(3×4)

-96 (-3) = 288:

(288 x^4)/(3×4)

3×4 = 12:

(288 x^4)/12

Kendra swims 126 miles in 3 days, what is the constant rate that Kendra swims per day? a. 40 miles per day c. 42 miles per day b

Leni [432]

Answer:

c. 42 miles per day

Step-by-step explanation:

From the information given, you can use a rule of three to calculate the constant rate that Kendra swims per day given that she swims 126 miles in 3 days:

3 days → 126 miles

1 day → x

x=(1*126)/3=42 miles

According to this, the answer is that Kendra swims 42 miles per day.

a local high schools cheerleading squad is selling snow cones during lunch to raise money for a national cheerleading competitio

svlad2 [7]

We have:

Volume of cone = 535 cm³ at the maximum
Height of cone= 8cm

We know the formula to find volume of cone is $\frac{1}{3} r^{2} \pi h$

We need to find the radius of the base of the cone
$535= \frac{\pi r^{2}8} {3}$
$535*8= \pi r^{2}$
$\frac{4280}{\pi}= r^{2}$
$r= \sqrt{ \frac{4280}{ \pi} }$
$r=36.9$ to the nearest one decimal place

The width of the opening of the cone is the diameter of the circle. Diameter is twice the radius, hence 2×36.9=73.8 cm
