Given: m∠QVR = 49°

Prove: x = 15

Answers

Answer 1
Answer:

Answer:

see the procedure

Step-by-step explanation:

The picture of the question in the attached figure

we know that

m\angle QVR=m\angle TVU ----> by vertical angles

substitute the given values

49^o=(3x+4)^o

solve for x

subtract 4 both sides

3x=49-4\n3x=45

divide by 3 both sides

x=45/3\nx=15
Answer 2
Answer:

Answer:

the reason for 4 -> vertical angles theorem

3x + 4 = 49 is the answer for the other one

Step-by-step explanation:

Hope this helps. You’re welcome!

The orchard needs to fills n order for 156 apples using both large and small bags. What is the least number of each type of bag that could be used if each bag is completely filled?

Answers

I find a similar question that looks like this:
The apples can be packed into a large bag that holds 9 apples or a small bag that holds 6 apples. The orchard needs to fill an order for 156 apples using both large and small bags. What is the least number of each type of bag that could be used if each bag is completely filled?

The correct answer for the question that is being presented above is this one: 
Given is 16 large bags and 2 small bags.

16 * 9 =144

2 * 6 = 12

144 + 12 = 156

What is the mean absolute deviation (MAD) of the data set? {5, 9, 9, 11, 16}

Answers

Using it's concept, it is found that the mean absolute deviation (MAD) of the data set is of 2.8.

The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.

In this problem, the mean is:

M = (5 + 9 + 9 + 11 + 16)/(5) = 10

Hence, the mean absolute deviation is:

MAD = (|(5 - 10)| + |(9 - 10)| + |(9 - 10)| + |(11 - 10)| + |(16 - 10)|)/(5) = 2.8

The mean absolute deviation (MAD) of the data set is of 2.8.

A similar problem is given at brainly.com/question/22355667
Mean absolute deviation is the average of the sum of all deviations of the terms from the average of the terms...

mean=(5+9+9+11+16)/5=10

mad=[(10-5)+(10-9)+(10-9)+(11-10)+(16-10)]/5=2.8

9 ten thousands divided by ten

Answers

The answer is 9,000 or 9 thousand.

Further explanation

9 ten thousand are a unit form. The standard form is 90,000.

Explanations and an example of questions about the four types of number forms can be found at brainly.com/question/4725342.

The key problem is working out the value of 90,000 divide by 10. This is a division operation.

\boxed{90,000 / 10 = ?}

Option-1

Both numbers are divided by 10.

\boxed{90,000 / 10 = 9,000 / 1}

The result is \boxed{90,000 / 10 = 9,000}

Option-2

Division operations can be written as fractions, like this.

\boxed{(90,000)/(10) = ?}

The numerator and denominator are both divided by 10, or 'cross out a zero from both'.

\boxed{ = (9,000)/(1)}

The result is \boxed{90,000 / 10 = 9,000}

- - - - - - -

If x is divided by y equals z, then x is equal to y multiplied by z.

\boxed{If \ x / y = z \ or \ (x)/(y) = z, then \ x= y \cdot z}

Let's prove it!

\boxed{If \ 90,000 / 10 = 9,000 \ or \ (90,000)/(10) = 9,000, then \ 90,000 = 10 \cdot 9,000}  

This is proven.
