Answer:

b.

Step-by-step explanation:

hope this helps

Answer 2

The velocity of the train is 30 km/h west.

Definition of velocity

Velocity can be determined by dividing the total displacement travelled by the total time travelled. The direction of travel is also added.

Calculation of velocity Total displacement = 80 km + 40 km = 120 km Total time = 1 hour + 1 hour + 2 hours = 4 hours Direction = west

Velocity = 120 km / 4 hours = 30 km/h west.

The student council raised $2,790 during its annual fundraiser. The money was shared equally among the Events Committee, the Sports Committee, and the Sunshine Committee. a. The Sports Committee wants to use its share of the money to purchase t-shirts. If each t-shirt costs $12, what is the greatest number of t-shirts the Sports Committee can purchase? ANSWER NOW PLEASE!!!!

Answers

Answer:

77

Step-by-step explanation:

$2790 is shares equally between 3 committees. each committee would get - $2790 / 3 = $930

If a shirt costs $12 and the Sports Committee gets $930, the committee would get $930 / $12 = 77.5

The committee cannot get half a shirt, so the greatest number of shirt that can be purchased is 77

Graph y= –3x+4. (I WILL MARK BRAINLIEST)

Answers

Answer:

See attached

Step-by-step explanation:

Given function:

y= –3x + 4

To graph the line we need two points

One of the easy points is the y-intercept:

(0, 4)

Another point can be taken depending on the slope. With the slope of -3, we select x = 2 and find its y- coordinate:

y = -3(2) + 4 = -6 + 4 = -2

So we have points

(0, 4) and (2, -2)

Plot these points and connect with the line and we are done.

The sum of two numbers is 10. Their difference is 6. What are the two numbers? ​

Answers

Answer: 8 and 2

Step-by-step explanation:

this is simple, since we only have 10 numbers to work with. i just kept experimenting with numbers until i got one that had a difference of 6. no strategy, just brain power. hope this helps! xoxo

Answer:

So negatove numbers are gonna be impossible becuase we know that the highest we can go is -10+20=10 but it’ll give a whole different difference when subtracted.

And it can’t be greater then 10 becuase if you do add them it won’t be 10

SO it has to be between 1-10

So what equals 10?

5/5

2/8

8/2

6/4

4/6

3/7

7/3

Now 5 and 5 is out cause if subtracted its 0

2/8  and 8/2 works, if added you get 10 but when subtracked the way for 8/2 from left to write it’ll give 6 which is the only one which will give.

final answer the two numbers are 8 and 2

If a varies jointly as b and c,
and a=6 when b=2 and a=3.
Find the variation constant and
the equation of variation.​

Answers

Given:

a varies jointly as b and c.

a=6 when b=2 and a=3.

To find:

The variation constant and the equation of variation.

Solution:

a varies jointly as b and c.

[tex]a\propto bc[/tex]

[tex]a=kbc[/tex]              ...(i)

Where, k is the constant of proportionality.

a=6 when b=2 and a=3.

[tex]6=k(2)(3)[/tex]

[tex]6=6k[/tex]

[tex]\dfrac{6}{6}=k[/tex]

[tex]1=k[/tex]

The value of k is 1.

Putting k=1 in (i), we get

[tex]w=1xy[/tex]

[tex]w=xy[/tex]

Therefore, the variation constant is 1 and the equation of variation is [tex]w=xy[/tex].

Given the lengths of sides XY and XZ as shown in triangle XYZ below, what is the length of side YZ?

a. 5√13

b. 12

c. √194

d. 18

e. 5√5

Answers

Answer:

YZ = 12

Step-by-step explanation:

From the question given above, the following data were obtained:

Length of XZ = 13

Lenght of XY = 5

Lenght of YZ =?

The length of YZ can be obtained by using pythagoras theory since the figure is a right angle triangle. This can be obtained as follow:

XZ² = XY² + YZ²

13² = 5² + YZ²

169 = 25 + YZ²

Collect like terms

169 – 25 = YZ²

144 = YZ²

Take the square root of both side.

YZ = √144

YZ = 12

Therefore, the length of YZ is 12

d = √389

Step-by-step explanation:

to find c we use 15 and 8 into the formula of "a^2 + b^2 = c^2" which is 17. Now we use 17 and 10 as a and b to find c in the formula which is d.

a^2 + b^2 = c^2

10^2 + 17^2 = x^2

100 + 289 = x^2

389 = x^2

√389 = √x^2

Answers

Answer:

(x2 , y2) = (22,50)

Step-by-step explanation:

Given:

m1 : m2 = 1:4

(x1 , y1) = (7 , 5)

(X ,Y) = (10 ,14)

Find:

(x2 , y2)

Computation:

X = (m1x2 + m2x1) / (m1+m2)

10 = [(1)(x2) + (4)(7)]/(1+4)

10 = [x2 + 28]/5

22 = x2

Y = (m1y2 + m2y1) / (m1+m2)

14 = [(1)(y2) + (4)(5)]/(1+4)

14 = [y2 + 20]/5

70 = y2 + 20

50 = y2

(x2 , y2) = (22,50)
