The sides of a rectangle are 8cm and 6cm. What is the length of the diagonal. 12cm 10cm 9cm 7cm

tatiyna

Answer:

10 cm

Step-by-step explanation:

The diagonal d divides the rectangle into 2 right triangles with legs 8 and 6 and hypotenuse d

Using Pythagoras' identity in one of the right triangles, then

d² = 8² + 6² = 64 + 36 = 100 ( take square root of both sides )

d = $\sqrt{100}$ = 10 cm

The employees of a hardware store ordered lunch from a local delicatessen. The lunch consisted of 4 turkey sandwiches and 7 orde

AleksandrR [38]

Answer:

Charges of Turkey is $6.25

Charges of French Fries is $1.90

Step-by-step explanation:

Given

Represent Turkeys with T and French Fries with F;

$4T + 7F = 38.3$

$5T + 5F = 40.75$

Required

Determine the values of T and F

$5T + 5F = 40.75$

Divide through by 5

$T + F = 8.15$

Make F the subject

$F = 8.15 - T$

Substitute 8.15 - T for F in the first equation

$4T + 7F = 38.3$

$4T + 7(8.15 - T) = 38.30$

$4T + 57.05 - 7T = 38.30$

Collect Like Terms

$4T - 7T = 38.30 - 57.05$

$-3T = -18.75$

Solve for T

$T = -18.75/-3$

$T = 6.25$

Recall that:

$F = 8.15 - T$

$F = 8.15 - 6.25$

$F = 1.90$

Calculate the velocity of a moving train with a mass 10,000kg and 150,000J of energy.

Viefleur [7K]

Kinetic energy possessed by moving train is $E_k = 150000J$ .

And mass $m = 10000kg$ .

The formula for kinetic energy is $E_k = \frac{m\times v^2}{2}$ .

Solve for velocity:

$E_k = \frac{m\times v^2}{2}\implies 2E_k = m\times v^2$

$v^2=\frac{2E_k}{m}\implies \underline{v = \sqrt{\frac{2E_k}{m}}}$

Now put in the data:

$v = \sqrt{\frac{2\times150000J}{10000kg}}\approx5.48\frac{m}{s}$
