Step-by-step explanation:

When you get 9^8 the answer is 43046721. So when raising a power to a power, the products should equal 8. Using simple math, we can determine that 4x2=8. To check our work you can calculate (9^2)^4, which equals 43046721. Now we can now for sure that this answer is correct. Hope this helps!

We have proven that ΔACO ≅ ΔBDO using the SAS (Side-angle-side) theorem

Congruent triangles

From the question, we are to prove that ΔACO ≅ ΔBDO

From one of the congruent triangles theorem, we have that

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

This is the SAS (Side-angle-side) theorem.

From the given information,

AB and CD intersect at point O

Thus, AO = BO

Also,

∠ACO ≅ ∠BDO

In the diagram, we can as well observe that CO ≅ DO

Thus, we can conclude that AC ≅ BD

Since sides AC, CO and the included angle ACO are congruent to sides BD, DO and the included angle BDO, we can conclude that ΔACO ≅ ΔBDO using the SAS theorem.

Hence, we have proven that ΔACO ≅ ΔBDO

What is the COMMISSION:
A sales man of machinery sold 148 machines at $79.50 each. If he received a commission of 7 1/2% then how much was his commission.

Answers

7 1/2% of $79.50 - $5.60
Commission/PER ($5.60) Sold - 148
$5.60x148 - $828.80
Total commission earned $828.80

Hope this helps!
you can do this two ways by either finding the total for all his sales then get his commision or find commision per machine then multiply by amount of machines sold. it doesnt matter just depends on pref. so imma do the first one

79.5 x 148 =11766
11766 x .075(commision) =882.45
so this man earned $882.5

Here is a tree diagram showing the sample space for two independent events. What is the probability of getting a total of 13 or more?

Answers

Using it's concept, there is a 0.6667 = 66.67% probability of getting a total of 13 or more.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

From the tree diagram, there are 9 outcomes, of which 6 result in a total(first node + second node) of 13 or more, hence the probability is:

p = 6/9 = 0.6667.

A batch of cookies is 24 cookies. It cost Courtney 134 dollars and 40 cents to make 10 batches of cookies.
How much does it cost Courtney to make 1 batch of cookies? Round to tenths places if necessary.
How much does it cost her to make 1 cookie? Round to the tenth place if necessary.

Answers

Answer:

13 dollars and 44 cents, 56 cents.

Step-by-step explanation:

134 dollars are 40 cents = 134.4 dollars.

10b = 134.4

b = 13.44

13 dollars and 44 cents

There are 24 cookies to a batch

24c = 13.44

c = 0.56.

so each cookie costs 56 cents

Answer:

13.44 to make 1 batch. 0.56 to make 1 cookie.

Step-by-step explanation:

If it cost 134.40 to make 10 batches, then you would divide that by 10 for how much it cost for 1 batch.

Then, 1 batch of 24 costs 13.44, you would divide it by 24 for the cost of 1 cookie.

Answer: Both C and D are correct

To remove the exponent from the v you need to square root both sides,

the exponent on the v is then canceled out giving you:

Answer:

Both C & D are correct

Step-by-step explanation:

[tex]v^{2} =\frac{25}{81}[/tex]

Root both sides of the equation to remove the square.
