4+2(5*7) please help me do this, km in year 10!

Answers

Answer 1

Answer: $4+2\cdot(5\cdot7)\n\nfirst:5\cdot7=35\n\n4+2\cdot35\n\nnext:2\cdot35=70\n\n4+70\n\nfinish:4+70=74$

Answer 2

Answer: First do 5*7 = 35
This is what the equation looks like then 4+2(35)
Since the 2 is next to the ( ) that means you multiply. So 35*2 = 70
Then the last part is 70+4 = 74 !

A grocery store sells chili peppers at $2.04 for a dozen. At this rate, what's the cost per pepper?

Answers

0.17 because you would do $2.04/12=0.17 so that would be the answer want to check it do 0.17*12=2.04 so 0.17 is your answer

There is a vfery simple way to answer this question, and that is to take your amount(in this case 2.04) and divide it by your rate(a dozen=12). 2.04/12=0.17.

If 2n=14 what Is 8n? I am really bad at algebra and I need to do my homework

Answers

To solve this, you must first find out the value of n. Use algebra to get n by itself:
2n = 14
/2 /2
n = 7
Now, find out what 8n is by multiplying 8 and n.
8n
= 8(7)
= 56

So, 8n = 56
Hope that helps!

2n = 14
divide both by 2
n = 7
now multiply by 8
7*8
56

My son, Garrett, is 11 years old and has a piggy bank that he wants to fill. He started with 5 one dollar bills. Every Saturday he earns 3 more dollar bills for chores he’s completed. How many one dollar bills will he have by the end of 10 weeks?1. Write a function model, M(x), that represents the total number of one dollar bills garret will have in one dollar bills, x

2. Identify the independent and dependent quantity.

3. The domain and range are represented as discrete or continuous?

4.What is a reasonable domain and range for this scenario?

Thanks for the help!

Answers

Answer:

1) M(x) = 5 + 3x

2) Dependent variable; 3 dollar bills

Independent variable: chores

3) Range is continuous

Domain is discrete

4) Range: 0 ≤ x ≤ 10

Domain: 5 ≤ M ≤ 35

Step-by-step explanation:

We are told he started with 5 number of $1 dollar bills and that every Saturday, he earns 3 more $1 dollar bill.

Thus, total number of $1 bills earned after x number of Saturdays(weekly) is;

M(x) = 5 + 3x

After 10 weeks, total number is;

M(10) = 5 + 3(10)

M(10) = 35

The dependent variable is the 3 more dollar bills earned each Saturday because it depends on chores he completed. While the independent variable is the chores because it doesn't depend on anything.

After 10 weeks, the range and domain will be;

Range: 0 ≤ x ≤ 10

For the; Domain:

For x = 1, M(0) = 5 + 3(0) = 5

M(10) = 35

Thus;

Domain: 5 ≤ M ≤ 35

The range could be all numbers in the interval from 0 to 10. Thus, it is continuous.

Whereas, the domain doesn't contain all the numbers in the interval from 5 to 35. Thus it is Discrete.

What is the sum of square root of -2 and square root of -18?

Answers

Answer:

4 Square root 2i

Step-by-step explanation:

if you're ed then this the answer I hope this helps

√-2 + √-18

√-2 = √(-1*2) = √-1 * √2 = i√2 Recall square root of -1 = i

√-18 = √(-1*18) = √-1 * √1`8 = i√18 Recall square root of -1 = i

But √18 = √(9*2) = √9 * √2= 3√2

√-18 = i√18= i(3√2) = 3i√2

√-2 + √-18 = i√2 + 3i√2 = (i + 3i)√2 = 4i√2

So the sum is 4i√2, where i = √-1

Hope this explains it.
