It's b because

both are at 325 distance, and since liza moves at a faster speed, she will pass by ralph in 5 hours

Answer:

B

Step-by-step explanation:

Solving the system, x = 5 and y = 325

Answer:

40 degrees.

Step-by-step explanation:

A circle has a total of 360 degrees.

If a third of the circle remains, it will have one third that amount.

360 / 3 = 120

So 120 degrees remain.

If the remaining amount is cut into three slices, each slice will be one third of that amount.

120 / 3 = 40

Each slice has an angle measure of 40 degrees.

Answer:

c. r=14

Step-by-step explanation:

r+36=50

subtract 36 from both sides

r+36-36=50-36

r=14

Step-by-step explanation:

If you complete the square, you will add a right triangle with legs 10 - 6 = 4 ft.

The area of the figure is:

Answer:

50

Step-by-step explanation:

[tex]7x = (90 + 5x) \times \frac{1}{2} [/tex]

[tex]7x = {2.5x} + 45[/tex]

[tex]4.5x = 45[/tex]

[tex]x = 10[/tex]

Plug 10 in for x.

[tex]5(10) = 50[/tex]

The measure of arc EC is 50. Exterior angle theorem is used in the given problem.

The sum of the exterior angles of a regular polygon with any number of sides equals 360°.

The exterior angle of a polygon is the angle of rotation between one extended side and its neighboring side, which is not extended.

Furthermore, because the polygon is regular, even though it has 'n' sides, all the outside angles have the same measure, and hence their measure is (360/n)°.

The measure of arc EC is found as;

[tex]\rm 7x = (90+5x)\times \frac{1}{2}\\\\ 7x=2.5x+45\\\\ 4.5 x=45 \\\\ x=10[/tex]

From the diagram,he EC is 5x . The measure of arc EC is;

EC=5x

EC=5×10

EC=50

Hence,the measure of arc EC will be 50.

Answer:

A=12

Step-by-step explanation:

Answer:

x = 38

Step-by-step explanation:

Here, we can use the area formula A = 0.5(Bh) to solve for x.

In this case, A = 399, B = x, and h = 21

[tex]399 = \frac{21}{2} x\\x = \frac{2*399}{21} \\x = 38[/tex]

Answer:

What numbers are 1.2 and 1.4 on the number line? Huh?

Answer:

7t=c

Step-by-step explanation:

Well since ”t” stands for hours and ”c” stands for total cost.

According to the graph for 1 hour theres a charge of 7 dollars. So 7t ehich will equal to the cost c.

7t=c

Answer: 4/35

Step-by-step explanation:

Number of red marbles = 4

Number of blue marbles = 5

Number of green marbles = 6

Total number of marbles = 4+5+6 = 15

When a red marble is picked, the probability is 4/15, then to pick a green marble after that, we have 14 marbles left and probability of picking green is 6/14.

Now, probability of choosing a red marble from the bag, not putting it back, and then choosing a green marble will be:

= 4/15 × 6/14

= 24/210

= 4/35

Give me the formula and i can do it

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

Given that :

Miles ridden in Tuesday = 10

Miles ridden on Wednesday = 20

Sample size, n = 2

Mean :

(10 + 20) / 2

= 30 /2

= 15

Mean absolute deviation :

(|10 - 15| + |20 - 15|) / 2

(5 + 5) / 2

10 / 2

= 5

Answer:

B. $145.00

Step-by-step explanation:

4(x+15)= 640

or, 4x+60=640

or, 4x = 640-60

or, 4x = 580

or, x = 580/4

x= 145

Answer:

C

Step-by-step explanation:

Test all of the coordinates given to you.

Starting with the X's. (because they are all positive, move to the right.)

Go right in the direction based on the number given

then go up or down for the Y's depending on the number given.

Answer:

Step-by-step explanation:

This is because,

According to Triangle Inequality Property:

Measurement of any two sides of a triangle is always greater than the third side.

Here,

10 + 16 = 26 > 21

10 + 16 = 26 > 22

10 + 16 = 26 > 22

But,

10 + 16 = 26 < 27

Hence,

Option D: 27 can't be the measurement of the triangle.

Answer: D
