Answer:

$\frac{114}{13}$ or 8 $\frac{10}{13}$

Step-by-step explanation:

1) Convert the mixed numbers to improper fractions

3+ $\frac{15}{2}$ ÷ $\frac{13}{10}$

2) To divide by a fraction, multiply by the reciprocal of that fraction

3+ $\frac{15}{2}$ × $\frac{10}{3}$

3) Reduce the numbers with the greatest common factor 2

3 + 15 × $\frac{5}{13}$

4) Calculate the product

3 + $\frac{75}{13}$

5) Calculate the sum

$\frac{114}{13}$ = 8 $\frac{10}{13}$

A 67-kilogram cannon fires a 1 kilogram cannonball at 45 m/sec. If the cannon is on wheels, at what speed does it move backward?

PtichkaEL [24]

Answer:

-1.4 m/sec [backwards]

Step-by-step explanation:

The energy of the cannon moving should be equal to the energy contained in the cannonball. Kinetic energy for each is calculated using KE = (1/2)m $v^{2}$

Let x be the speed of the cannon.

Cannonball: 

KE = (1/2)m $v^{2}$

KE = (1/2)(1kg)(45 m/sec)^2

KE = 22.5 kg*m/sec^2

Cannon: [The cannon will have the reverse energy]

KE = - (1/2)m $v^{2}$

22.5 kg*m/sec^2 = -(1/2)(67 kg)x^2

22.5 kg*m/sec^2 = -(33.5 kg)x^2

x^2 = (33.5 kg)/(22.5 kg*m/sec^2)

x^2 = -1.4 m/sec [backwards]

Find the area of the circle to the nearest hundredths ( Use 3.14 for pi) (4cm)

Tpy6a [65]

Answer: 50.24 cm²

Step-by-step explanation:

ASSUMING THE RADIUS OF THE CIRCLE IS THE 4 CM

The formula for the area of a circle is pi(3.14) * r(4)^2

$3.14*4^2$

$3.14*16$

$50.24$

PLEASE HELP! DUE AT 11:59 PST

Nesterboy [21]

Answer:

Y = 15x + 30 and 8 hours

Step-by-step explanation:

She gets $15 per hour so her income is based on her hours, but we don't know what that is yet so, 15x.

She gets a solid $30 every week that is straight forward

To solve the function

150 = 15x + 30

subtract 30 from both sides

120 = 15x

divide 15 from both sides

8 = x

x = 8

You got this :)

Candy and Tim share a paper route. It takes Candy 85 min to deliver all the papers, and it takes Tim 65 min. How long does it ta

RSB [31]

Answer:

The time required to finish the work by both candy and Tim working together = 36.83 minute

Step-by-step explanation:

Time taken by the candy to finish the work $T_{1}$ = 85 min

Time taken by the Tim to finish the work $T_{2}$ = 65 min

Thus the time taken by both to finish the work = $\frac{T_1 \times\ T_2}{T_1 + T_2}$

Put the values of $T_{1}$ and $T_{2}$ we get ,

$T_{}$ = $\frac{85 \times\ 65}{85 + 65}$

$T_{}$ = $\frac{221}{6}$

$T_{}$ = 36.83 minute

Thus the time required to finish the work by both candy and Tim working together = 36.83 minute
