plz hury i am on a test

Answers

Answer 1

Answer:

72

Step-by-step explanation:

18*4

12*6

8*9

Answer 2

Answer: LCD = 72

Step-by-step explanation:

Rewriting input as fractions if necessary:

1/8, 1/12, 7/18

For the denominators (8, 12, 18) the least common multiple (LCM) is 72.

LCM(8, 12, 18)

Therefore, the least common denominator (LCD) is 72.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 9/9 = 9/72

1/12 = 1/12 × 6/6 = 6/72

7/18 = 7/18 × 4/4 = 28/72

at 9 am you have to run 2 miles. at 9:24 am you have run 5 miles. what is your running rate in minutes per mile

Answers

The answer is 5 minutes
You ran three miles in 24 minutes so your rates is 3/24 miles per minute
To convert to miles per hour you would multiple by 60minutes/1hr
So 3/24 x 60/1 which simplifies to
15/2 miles per hour

What is the probability of rolling either two identical numbers or rolling a sum of 8 using two number cubes, each labeled 1 – 6?

Answers

Answer:

5/18

Step-by-step explanation:

We have 2 things to consider here, rolling two identical numbers, or rolling a sum of 8

Rolling two identical numbers

To make this simple, think about how many possibilities there are to have two identical numbers. (1,1) (2,2) (3,3) (4,4) (5,5) (6,6). The total amount of possibilities for rolling two dice is 6*6 which is 36. That would be 6/36 which is 1/6

Rolling a sum of 8

The numbers which add up to 8 are, (2,6)(3,5)(4,4)(5,3)(6,2). With 36 total possibilities, it would be 5/36.

However, we can see, (4,4) is repeated, so we have to subtract 1/36.

Answer

1/6 + 5/36 - 1/36

6/36 + 5/36 - 1/36

10/36

5/18

Answer:

5/18

(explain answer) Helpp pleasee!! asap

Answers

Answer:

x = 30 degrees

Step-by-step explanation:

When two parallel lines are intersected by a transversal, the alternate corresponding angles are supplementary, meaning their degree measures add up to 180. One can apply this here by stating that the two given angles add up to 180. Then one can simplify and use inverse operations to solve for (x).

(6x - 5) + (x - 25) = 180

6x - 5 + x - 25 = 180

7x - 30 = 180

    +30    +30

7x = 210

/7      /7

x = 30

x=30 i hope this helped

Write the equation of the line in slope-intercept form.

The equation of the line in slope-intercept form is

Answers

Answer:

y = 50x + 20

Step-by-step explanation:

[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

Use the slope-intercept formula to find the slope.

[tex]m = \frac{120 - 20}{2 - 0}[/tex]

[tex]m = \frac{100}{2} = 50[/tex]

The y-intercept is where the line crosses the y-axis.

Answer:

y = 50x + 20

Step-by-step explanation:

finding slope or gradient, choose any two points on the line i.e (2.0, 120) and (0.0, 20)

m = (y2 - y1)/(x2 -x1)

= (120-20)/(2.0-0.0)

= 100/2

= 50

finding the equation of the line using point (0,20)

=> y = mx + c

=> 20 = 50*0 + c

=> c = 20

so equation of the line

=> y = 50x + 20

Trapezoid ABFE is similar to trapezoid EFCD. What is the length of DC?

Answers

Answer:

6.75

Step-by-step explanation:

Find the relationship between the trapezoids. You can see that the top of trapezoid ABFE is 3 units and the top of EFCD is 4.5 units. 3 * 1.5 = 4.5, so t the sides of trapezoid EFCD are 1.5 times more than the sides of ABFE.

Now, you know the bottom of ABFE is 4.5, so the bottom of EFCD is 1.5 times longer because they are proportional, so you can do 4.5 * 1.5 = 6.75 units.

Nemo swims from point A(-4,8) to point B(-8,2) then finally to point C(-5,4) creating a triangle. Dory watched Nemo swim and tried to reflect his movements. Dory swam from A'(4,8) to point B'(-8,2) to point C'(5,4) which also created a triangle. Examine the points and determine if Dory made the right movements to be considered a reflection. Is it a reflection?

Answers

Answer:

No, because point B' should be (8,2), since this is a reflection across the y-axis

Step-by-step explanation:

Answer: Dory did not go in Nemo's direction corectly

Step-by-step explanation: Dory when to (4,8) insted of (-4,8) so is she went to -4,8 then she would have been in a correct triangle

Answer:

x = 120 degrees

Step-by-step explanation:

you would do 70+50 = 120

360 - 120 = 240

240 / 2 = 120

I got the 360 degrees because I thought of the it as a circle instead of triangles.

Answers

Answer:

We can identify which case it is by looking at our results. If we end up with the same term on both sides of the equal sign, such as 4 = 4 or 4x = 4x, then we have infinite solutions. If we end up with different numbers on either side of the equal sign, as in 4 = 5, then we have no solutions.Step-by-step explanation:
