Answer:

70 degrees = a

Step-by-step explanation:

Triangle= 180 degrees.

Therefore, since a and the unmarked angle are congruent since it is an isosceles triangle, we subtract 40 from 180, with a result of 140. With 140, we divide by 2 to find the degrees for both the unmarked angle and angle a, since they are congruent. 140/2 = 70, Angle A will equal to 70 degrees

---- = ----------

5 AC

4 10

---- = ----------

5 AC

Using cross products

4 * AC = 5*10

4AC = 50

Divide by 4

AC = 50/4

Given the function P(x)=(x-1)^2 write the new function with a Dilation of 2 On THE X

yaroslaw [1]

Answer: New function is $y=2(x-1)^2.$

Step-by-step explanation:

A dilation is a transformation that creates an image using a scale factor that has the exactly same shape as the original, but have a different size.

The given function : $P(x)=(x-1)^2$

We know that any function y= f(x) will become y=k f(x) after dilation of k units on the x, where k= scale factor for dilation.

Here, the given scale factor = 2 i.e. k=2

Then, the new function will be :

$2P(x)=2(x-1)^2$

Hence, the new function is $y=2(x-1)^2.$

X and Y are in partnership with capital contributions of $50000 and $30000 respectively.

Tamiku [17]

Answer:

The correct answer is B. $13,875.

Step-by-step explanation:

Since X and Y are in partnership with capital contributions of $ 50000 and $ 30000 respectively, and the partnership agreement provides that profits are to be shared in proportion to capital contributions and each partner is entitled to 10% interest on capital, and profit for the year was $ 37000, to determine what was the total amount credited to Y’s current account at the end of the year the following calculation must be performed:

50,000 + 30,000 = 80,000

80,000 = 100

30,000 = X

30,000 x 100 / 80,000 = X

37.5 = X

37,000 x 0.375 = X

13.875 = X

If i have 13 gallons of water and i pour 10 out and have about 10.6 in the countainer i poured it in how much would i have left

MrMuchimi

Given:

I have 13 gallons of water and I pour 10 out.

I have about 10.6 in the container I poured it in.

To find:

The the remaining water.

Solution:

I have 13 gallons of water and I pour 10 out. So, the remaining water after this step is

$13-10=3$

Then, I have about 10.6 in the container I poured it in. So, the remaining water after this step is

$3+10.6=13.6$

Therefore, the final remaining amount of water is 13.6 gallons.
