Answer:

gcf = 13

13(1+5)

Step-by-step explanation:

GCF = 13, 13*5=65

= 13 + 13(5)

= 13(1+5)

which also = 13(6) = 78 = 13 + 65

The gcf for 13 and 65 is 13 because that is the greatest number that 13 and 65 can divide into and for the 2nd question it is 13(1+5) bc you put the 13x1 equal 13 and 13x5 equals 65 so ya.

A 290-kg flatcar 28 m long is moving with a speed of 6.5 m/s along horizontal frictionless rails. A 95-kg worker starts walking

blsea [12.9K]

Answer:

9.33 seconds

60.67 meters

Step-by-step explanation:

A worker with a speed of 3.0 m/s with respect to a car, starts to walk from one end of the car to the other in the direction of motion of the car.

As the car is 28 m long, then the worker will reach the other end of the car in $\frac{28}{3} = 9.33$ seconds. (Answer)

Now, the car is moving with a speed of 6.5 m/s and in the time of 9.33 seconds, it will move by $6.5 \times 9.33 = 60.67$ meters. (Answer)

At last week's track meet, Stacy ran 9/12 of a km, Jules ran 4/5 of a km, and Raul ran 3/4 of a mile. Which two students ran the

koban [17]

Answer: No two students ran same distance

Step-by-step explanation:

Given

Stacy ran $\frac{9}{12}$ of a km i.e.

$\Rightarrow 1\times \dfrac{9}{12}=\dfrac{3}{4}=0.75\ km$

Jules ran $\frac{4}{5}$ of a km i.e.

$\Rightarrow 1\times \dfrac{4}{5}=0.8\ km$

Raul ran $\frac{3}{4}$ of mile i.e.

$\Rightarrow 1\times \dfrac{3}{4}=0.75\ miles\\\\\text{1 mile=1.6 km}\\\\\Rightarrow 0.75\ miles=1.2\ km$

So, no two students ran the same distance.

Hi Can you please help me

dimaraw [331]

Answer:

x = 68°

Explanation:

given ∠CBE = 22°
∠ABD is parallel to ∠CBE, thus has same angle of 22°
∠ADB is right angle and thus has 90° angle.
total sum of interior angles in triangle is 180°

We can find x by:

x + 90° + 22° = 180°

x + 112° = 180°

x = 180°- 112°

x = 68°
