Mathematics
1 answer:
Mashutka [201]3 years ago
5 0

Step-by-step explanation:

if Cora runs 1/2 mile per week and x is the number of weeks, then she will run 5+1/2x.

then determine how many weeks are in two and a half months ( depends on which month it is as there are less weeks in February than in January) but we could estimate 6.

for hana you will have 3+ 3/4x

first equation is y=5+ 1/2x and then plug 6 in for x to solve for y. the second equation is y=3+ 3/4x and plug in 6

Two figures are known as similar figures if there the corresponding angles are equal and the corresponding sider is in ratio. The value of x is 10. Thus, the correct option is B.

<h3>What are Similar Figures?</h3>

Two figures are known as similar figures if there the corresponding angles are equal and the corresponding sider is in ratio. It is denoted by the symbol "~".

Since the two prisms are similar, their sides will be in a common ratio. The value of the common ratio will be,

Common ratio = 4/2 = 5/2.5 = 3/1.5 = 2

Since the common ratio of every side is equal to 2, the value of x can be written as,

Common Ratio = 20/x = 2

20/x = 2

x = 10

Hence, the value of x is 10. Thus, the correct option is B.

18. An urn contains 3 red balls, 2 green balls and 1 yellow ball. Three balls are selected at random and without replacement fro
Goryan [66]

Answer:

27.77%

Step-by-step explanation:

The probability of not drawn a red ball is 3/6. The probability of not drawn a green ball is 4/6, and the probability of not drawn a yellow ball is 5/6. So, the probability of not drawn at least one color is the multiplication of the probabilities of each color, so (3/6)*(5/6)*(4/6) = 0.2777.

What is the distance from X to Y?
Rama09 [41]

Answer:

Step-by-step explanation:

To find the distance between two points, (A, B) and (C, D), you can use the following distance formula:

distance = \sqrt{(A - C)^{2} + (B - D)^{2}}

Plugging in the points from the problem, you'll get the following:

\sqrt{(0 - 9)^{2} + (6 - (-6))^{2}}

\sqrt{(-9)^{2} + (12)^{2}}

\sqrt{81 + 144}

\sqrt{225}
