Answer: Statements 1 and 2 shows that the coach blowing the whistle happened first.

Step-by-step explanation: The coach blowing the whistle as the first event can be seen only from statements 1 and 2 only.

From statement 1, "the referee blew the whistle" was followed by "the team ran onto the field."

From statement 2, "before the team ran onto the field" shows clearly that one event took place "BEFORE" the one being reported and the one that occurred before this one was "the referee blew the whistle."

Statement 3 which is "the referee blew the whistle, BUT..." indicates that the whistle was meant to prevent the team from from running onto the field. So if the referee blew the whistle, but the team ran onto the field, it means the whistle blowing was not supposed to make them run onto the field.

Statement 4, which states that "the referee blew the whistle BECAUSE the team ran onto the field" indicates that, the reason for blowing the whistle was because the team ran onto the field which clearly shows that the team ran onto the field first before the referee blew the whistle.

Statement 5, "WHILE the team ran onto the field..." clearly shows that both events took place at the same moment, and so the referee blowing the whistle could not have occurred first.

A=3 square root of 3<br> B=3<br> C=7<br> D=6
Neko [114]

Answer:

3\sqrt{3}

Step-by-step explanation:

This triangle is a 30°-60°-90° triangle, so you should always remember the rule shown in the picture. Because y is across from the 60° angle, it will be x\sqrt{3}. 3 is x because it is across from the 30° angle, so y will be 3\sqrt{3}.

The Russian ice breaker you mall can move forward through 2.3 m thick ice at a speed of 5.5 km/h. Right and solve a multiplicati
viktelen [127]

Answer:

The Multiplication equation to find the number of hours taken to travel the distance is 5.5\times x=82.5.

It will taken <u>15 hours</u> by  Russian ice breaker to travel a distance of 82.5 km through the ice.

Step-by-step explanation:

Given:

Thickness of the ice = 2.3 m

Speed while moving forward = 5.5 km/h

Distance to travel through the ice = 82.5 km

We need to write and solve the multiplication equation to find the number of hours taken to travel the distance.

Solution:

Let the number of hours taken to travel the distance be 'x'.

Now We know that;

By Distance formula;

Distance traveled is equal to Speed while moving forward multiplied by the number of hours taken to travel the distance.

framing in equation form we get;

5.5\times x=82.5

Hence The Multiplication equation to find the number of hours taken to travel the distance is 5.5\times x=82.5

On Solving above equation we get;

Dividing both side by 5.5 we get;

\frac{5.5x}{5.5}=\frac{82.5}{5.5}\\\\x=15 \ hrs

Hence It will taken <u>15 hours</u> by  Russian ice breaker to travel a distance of 82.5 km through the ice.

What is the equation of the line that passes through the point of intersection of the lines y = 2x − 5 and y = −x + 1, and is al
castortr0y [4]

Answer:

y = \frac{1}{2}x - 2

Step-by-step explanation:

Given lines,

y = 2x - 5,

y = -x + 1

Subtracting these two equations,

0 = 3x - 6

\implies 3x = 6

\implies x = \frac{6}{3}=2

By first equation,

y=2(2) -5=4-5 = -1

Thus, point of intersecting would be (2, -1).

Now, the equation of a line is y = mx + c,

Where,

m = slope of the line,

So, the slope of the line y=\frac{1}{2}x+4 is 1/2.

∵ two parallel lines have same slope.

Hence,

Equation of the parallel line passes through (2, -1),

y+1=\frac{1}{2}(x-2)

y+1=\frac{1}{2}x - 1

y = \frac{1}{2}x - 2

Marcus borrowed 9000 from his bank to buy a car. The bank charged him a simple interest rate of 1.25%. By the time he paid back
snow_lady [41]

Answer:

2.5 years

Step-by-step explanation:

Given data

P=9000

r= 1.25%

A= 9281.25

The simple interest expression is given as

A=P(1+rt)

substitute

9281.25= 9000(1+0.0125*t)

9281.25=9000+112.5t

collect like terms

9281.25-9000=112.5t

281.25= 112.5t

t= 281.25/112.5

t= 2.5

Hence the time is 2.5 years
