Answer:

It takes them 1.875 hours.

Step-by-step explanation:

Here, the job is cleaning the house.

Mom does 1 job in 3 hours.

In 1 hour, mom does 1/3 of the job.

Dad does 1 job in 5 hours.

In 1 hour, dad does 1/5 of the job.

Mom and dad working together do the job in x hours.

In 1 hour, mom and dad together do 1/x of the job.

1/3 + 1/5 = 1/x

5/15 + 3/15 = 1/x

8/15 = 1/x

8x = 15

x = 15/8 = 1.875

Answer: It takes them 1.875 hours.

A total of $10,000 is invested in two funds, Fund A and Fund B. Fund A pays 5% annual interest and Fund B pays 7% annual interes
RoseWind [281]

Answer:

The amount put in the account that paid 7% ( Fund B) was $6,500

Step-by-step explanation:

Let

x -----> the amount put in the account that paid 5% (Fund A)

$10,000-x -----> the amount put in the account that paid 7% (Fund B)

in this problem we have

5\%=5/100=0.05

7\%=7/100=0.07

so

630=x(0.05)+(10,000-x)0.07

630=0.05x+700-0.07x

0.07x-0.05x=700-630

0.02x=70

x=\$3,500

\$10,000-x=\$6,500

therefore

The amount put in the account that paid 7% ( Fund B) was $6,500

6³ ÷ 4 + 2 x 9(32 x 8 – 17 x 4).
inn [45]

ANSWER

3438

EXPLANATION:

<em>PARENTHESIS FIRST</em>

32 x 8 = 256

17 x 4 = 68

256 - 68 = 188

(<u>now the equation is, 6³ ÷ 4 + 2 x 9 (188))</u>

<u />

<em>EXPONENTS NEXT</em>

6³= 216

(<u>now the equation is, 216 ÷ 4 + 2 x 9 (188))</u>

<u />

<em>MULTIPLICATION AND DIVISION NEXT (left to right)</em>

216 ÷ 4 = 54

2 x 9 = 18

18 x 188 = 84

(<u>now the equation is, 54 + 3384)</u>

<u />

<em>LASTLY ADDITION AND SUBTRACTION (left to right)</em>

54 + 3384 = 3438

Ta-da!

Acme Corporation was able to increase its sales of widgets tenfold by creating a storefront on Amazon. Since Beta Corporation is
saveliy_v [14]

Answer:

reasoning is based on Literal Analogy

Step-by-step explanation:

According to my research on different types of reasoning methods, I can say that based on the information provided within the question Beta corporation's reasoning is based on Literal Analogy. This is when an individual compares two things by stating that one is similar to the other in almost every aspect. Which is what is happening in this situation since Acme corporation increased sales by making a storefront, then Beta Corporation believes that they can do the same because they are "literally" the same type of company because they sell the same products.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
