what is the length of line BC in the right triangle below?

Answers

Answer:

D. 39

Step-by-step explanation:

BC^2 = BA^2 + AC^2

BC^2 = 15^2 + 36^2

BC = square root (1521)

BC = 39

Answer:

D) 39

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean thm formula

Formula: a² + b² = c²

15² + 36² = c²

225 + 1296 = c²

1521 = c²

[tex]\sqrt{1521} =\sqrt{c^2}[/tex]

c = 39

He lives 50 m from a park.

The park is 275 m long and 200 m wide.

How far does he run in total?

Answers

We have to find the perimeter of the park and then add 50m to that

Perimeter = 2(l+b)

= 2(275+200)

= 2* 475

= 950m

Therefore: Total distance covered = 950+50 = 1000 m(1km)

Jose paid $1.12 for a dozen eggs at Target. How much would Jose have to pay for 18 eggs?

Answers

Answer:

56.16

Step-by-step explanation: All you do is just multiply

Answer:

$1.67

Step-by-step explanation:

Given it's $1.12 for 12 eggs, we divide 1.12 by 12 to see how much it cost for 1 egg

1.12/12 = 0.093

so 0.093 cents for 1 egg

0.093x18 eggs = 1.674 = $1.67

Answers

4.2 is also equal to 42/10 which is equal to 21/5. In order to find how many trips you will be dividing fractions (21/5) / (3/5). Although this may seems difficult, because the denominators are the same, it simplifies to 21/3 which is equal to 7 (A)

Answers

Answer:

x = 1/4

Step-by-step explanation:

Solve for x:

1 - 2 (1 - 2 x) = 0

Hint: | Distribute -2 over 1 - 2 x.

-2 (1 - 2 x) = 4 x - 2:

4 x - 2 + 1 = 0

Hint: | Group like terms in 4 x - 2 + 1.

Grouping like terms, 4 x - 2 + 1 = 4 x + (1 - 2):

4 x + (1 - 2) = 0

Hint: | Evaluate 1 - 2.

1 - 2 = -1:

4 x + -1 = 0

Hint: | Isolate terms with x to the left hand side.

Add 1 to both sides:

4 x + (1 - 1) = 1

Hint: | Look for the difference of two identical terms.

1 - 1 = 0:

4 x = 1

Hint: | Solve for x.

Divide both sides by 4:

Answer: x = 1/4

Answer:A=2,4,6,8

One way of writing this in set builder notation could be:

A={x|2≤x≤8|x2∈N}

Which can be interpreted as:

The set A is the set of any x such that 2≤x≤8 such that half of x is a natural number ( N ).

There are many ways of writing sets in set builder notation. Which is why it can be a little confusing to learn (the syntax) at first. Once you understand what all these new mathematical symbols mean (i.e. ∈ , | , N ), it becomes much easier to “read as a sentence”.

Here are a few more ways of writing the set A=2,4,6,8 in set builder notation:

A={x|2≤x≤8|x∈2⋅N}

A={x|(x−2)(x−4)(x−6)(x−8)=0}

A={x|x=2p|p∈{1,2,3,4}}

A={x∈N|mod(x,2)=0|x≤8}
