Answer:

1/8 ft³

Step-by-step explanation:

Apparently cubic blocks that are 1/5 of 2 1/2 ft on a side are used to fill the cube that is 2 1/2 ft on a side. Then each edge of the block is ...

(1/5) × (5/2 ft) = 1/2 ft

The volume of the block is the cube of that:

(1/2 ft)³ = 1/8 ft³

3.5 m = 350 cm

9.072 km = 9072 m

0.07 kg = 70 g

70.4 l = 70400 ml

79 m = 0.079 km

6 g = 6000 kg

5,870 m = 5.78 km

61,900 g = 61.9 kg

If a circle has a circumference of C, what is the area of the circle in terms of C? A. A=πC

mart [117]

The area of the circle is expressed in the formula A = pi r^2 while the formula of getting the circumference of the circle is C = 2pi *r. Trying to express A in terms of C, we square C first into C2 = 4pi^2r^2. In this case, the answer to this problem therefore is A = C^2/4 pi. Answer is B

Find the equation of a line that passes through the given points<br>(0,2) and (6,2)

AysviL [449]

Answer:

y=2

Step-by-step explanation:

To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-2}{6-0}=\frac{0}{6}=0$

Since the slop is 0, this is a horizontal line of the form y=b. B is the y-intercept of the points on the line. Notice that both are 2? y=2

Ling wants to save $87 for tickets to a rock concert if she has $23 now and will save $4 per week how long it take her to get en

VLD [36.1K]

In this case we have that the total cost of the tickets is $87.If she is $23, then she is missing:

$87-23 = 64$

He is missing $64.

If you can save $4 per week we have:

$4x \geq64$

Where "x" represents the number of weeks to work:

$x \geq \frac {64} {4}\\x \geq16$

So, Ling must work at least 16 weeks to get the money he needs for concert tickets.

Answer:

16 weeks

Stu trained for a triathlon for 5 hours yesterday. He ran 5 miles and then biked 80 miles. His biking speed is 15 mph faster tha

lara31 [8.8K]

Answer:

Step-by-step explanation:

Given as :

The distance cover while running = $D_1$ = 5 miles

Let The speed for running = $S_1$

The distance cover with bike = $D_2$ = 80 miles

The speed for biking = $S_2$ = 15 mph + $S_1$

Total Time taken = 5 hours

Now Time = $\dfrac{\textrm Distance}{\textrm Speed}$

∴ 5 hour = $\frac{D_1}{S_1}$ + $\frac{D_2}{S_2}$

Or, 5 hour = $\frac{5}{S_1}$ + $\frac{80}{15+S_1}$

Or, 5 hour = $\frac{75 + 5 S_1 + 80 S_1}{S_1(15+S_1)}$

or, 5 × ( $S_1^{2}+15 S_1$ ) = $85 S_1 + 75$

Or, $5 S_1^{2} + 75 S_1$ - $85 S_1 - 75$ = 0

or, $5 S_1^{2} -10 S_1 - 75$ = 0

or, $S_1^{2} -2 S_1 - 15$ = 0

Or, $S_1^{2} -3 S_1 + 5 S_1- 15$ = 0

Or, $S_1 (S_1 - 3) + 5 (S_1 - 3)$ = 0

Or, $(S_1 - 3) ( S_1 + 5 )$ = 0

∴ $S_1$ = 3 , - 5

So, the running speed = 3 mile per hour

And the biking speed = 15 mph + 3 mph = 18 mile per hour

Hence The running speed of Stu is 3 mile per hour . Answer
