Convert 3/5 into a fractions with a denominator of 20.

Sloan [31]

3 x 4 = 12
5 x 4 = 20

Since 5 times 4 is 20, then you must also multiply 3 by 4 because what you do to one part of the fraction you must do to the other.

If it took Carlos an hour to cycle from his house to the library yesterday, was the distance that he cycled greater than 6 miles

julia-pushkina [17]

Answer:

Option 2 is the correct answer.

Step-by-step explanation:

We know that

$Speed=\frac{Distance}{time}$

We have 1 mile = 5280 feet thus 6 miles = 31680 feet

Similarly 1 hour = 3600 seconds

Applying values in the equation above we get

$Speed=\frac{31680feet}{3600sec}\\\\Speed=8.8feet/sec$

Thus his average speed is less than 18feet/sec

As the figure shows Elton runs 500 m to point b first then he turns 100 degrees and runs another 350 m to point c how far is the

Alex777 [14]

Answer:

658.24 m

Step-by-step explanation:

Let A be the point from where Elton started. Connect points A and C, you get triangle ABC with AB=500 m, BC=350 m and m∠B=100°. Use the cosine rule to determine the length of the segment AC:

$AC^2=AB^2+BC^2-2\cdot AB\cdot BC\cdot \cos \angle B,\\ \\AC^2=500^2+350^2-2\cdot 500\cdot 350\cdot \cos 100^{\circ},\\ \\AC^2=250000+122500-350000\cdot (-0.174),\\ \\AC^2\approx 433276.8622,\\ \\ AC\approx 658.24\ m.$

(x+2)^2+(x-3)^2-2x^2)

garri49 [273]

Answer:

13 - 2x

Step-by-step explanation:

(x +2)² + (x - 3)² - 2x²

Expand.

(x + 2)(x + 2) + (x - 3)(x - 3) - 2x²

x² + 2x + 2x + 4 + x² - 3x - 3x + 9 - 2x²

Bring all the like terms together then simply.

x² + x² - 2x² + 2x + 2x - 3x - 3x + 4 + 9

2x² - 2x² + 4x - 6x + 13

= 13 - 2x (or -2x + 13 )
