Answer:

C. 13

Step-by-step explanation:

Apply pythagorean theorem.

Thus:

Diagonal AV = √(12² + 5²)

AV = √(144 + 25)

AV = √169

AV = 13 cm

The smiths have two children. The sum of their ages is 23. The produce of their ages is 132. How old are the children?

kolezko [41]

For this case we propose a system of equations:

x: Let the variable representing the age of the first child of the Smiths

y: Let the variable representing the age of the second child of the Smiths

According to the data of the statement we have to:

$x + y = 23\\x * y = 132$

From the first equation we have to:

$x = 23-y$

We substitute in the second equation:

$(23-y) * y = 132\\23y-y ^ 2 = 132\\y ^ 2-23y + 132 = 0$

We find the solutions by factoring:

We look for two numbers that, when multiplied, result in 132 and when added, result in 23. These numbers are 11 and 12.

Thus, we have that the factorized equation is:

$(y-11) (y-12) = 0$

Thus, the solutions are: $y_ {1} = 11\\y_ {2} = 12$

So, we can take any of the solutions:

With $y = 11$

Then $x = 23-11 = 12$

Therefore, the ages of the children are 11 and 12 respectively.

Answer:

The ages of the children are 11 and 12 respectively.

1-2 sin e cos 20-2 sin 40 = cos (20)

natka813 [3]

Answer:

No this is not the same as cos(2Ф)

Step-by-step explanation:

First I changed the $cos^{2}$ Ф into 1- $sin^{2}$ Ф

I then foiled the (1-2 $sin^{2}$ Ф)(1- $sin^{2}$ Ф) and that resulted in 1- $sin^{2}$ Ф-2 $sin^{2}$ Ф+2 $sin^{4}$ Ф

From there, I then cancelled the two 2 $sin^{4}$ Ф and combined like terms and was left with 1-3 $sin^{2}$ Ф

Now 1-3 $sin^{2}$ Ф ≠ cos(2Ф)

Angle ABC measures 140°. Angle DBC bisects ∠ABC. Angle EBC bisects ∠DBC. What is the measure of ∠EBC?

Brrunno [24]

Answer:

$\angle{EBC}=35\textdegree$

An angle bisector divides the angle measure into two equal parts. In triangle ABC, B is the point at which the angle lies.

Step-by-step explanation:

Picture segment BD drawn from point B of tri.ABC where it connects to segment AC, creating point D. Now picture E drawn on the newly created segment DC where it connects to point B and down to point C. Here's a drawing to better show this:

It's bisecting the bisected angle ABC. So, 140/2 = 70, and 70/2 = 35.

Percy buys tomatoes that cost $0.58 per pound. He pays $2.03 for the tomatoes, How many pounds of tomatoes does he buy?

MArishka [77]

Since each pound casts $0.58 and the total spent is $2.03, you divide 2.03 by .58 to find the total amount of pounds.
2.03/.58=203/58=3.5
Therefore, Percy bought 3.5 pounds of tomatoes.
