Answer:

1) word form

three million,two hundred and ninety eight thousand and seventy six

expanded form

5000000+3000+87

2)5,003,087

3)64,000,239

Answer:

x ≤ $12 a day

Step-by-step explanation:

5000-1400=3600

3600/300=12

Answer:

1200 dollars for interest, she must pay 6200

Step-by-step explanation:

8 percent of 5000 is 400 times 3 (years) is 1200

Answers:

=============================================

Work Shown:

a)

i = P*r*t

i = 5000*0.08*3

i = 1200 is charged in simple interest

---------------------------

b)

She must pay back the amount borrowed ($5000) which is the principal as well as the interest calculated in part a) earlier.

The total amount she must pay back is 5000+1200 = 6200 dollars

Answer:

x = 0

y = 3

Step-by-step explanation:

-x - 2y = - 6

0 - 2(3) = -6

6 = 6

-3x + 2y = 6

-3(0) + 2(3) = 6

0 + 6 = 6

Answer:

1 1/2 cups

Step-by-step explanation:

We can use ratios to solve

2/3 cup seed      x cups seed

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

4 cups mix            9 cups mix

Using cross products

2/3 *9 = 4x

6 = 4x

Divide by 4

6/4 = x

1 2/4 =x

1 1/2 =x

A. 1/1/2 cups

Step-by-step explanation:

So we know:

2/3 cup of sunflower seeds = 4 cups of trail mix

We need to find:

? cups of sunflower seeds = 9 cups of trail mix

Firstly, we find how many cup of seeds for 1 cup of trail mix:

? cup of sunflower seeds = 1 cup of trail mix

This we do by:

2/3 ÷ 4 = 1/6

so now we got,

1/6 cups of sunflower seeds = 1 cup of trail mix

now multiply by what we need to find (the 9 cups of trail mix) so the full answer will be

2/3 ÷ 4 = 1/6

1/6 x 9 = 1/1/2

Explanation:

We're given that time = 15

From this, we see that time < 12 evaluates to false, because 15 is not smaller than 12. Put another way, 15 < 12 is false.

But time < 18 is true since 15 < 18 is true. So we execute the second block of code and have the greeting variable be set to the string "good afternoon". This is what's displayed to the console without any quotes of course.

3. a = 18

Answer:

a=13+5=18 is a required answer

Answer:

3. a=18

is the required answer of your question

Answer:

x=6,y=16 that's what I got

Answer:

A. x = 3, y = -3

B. a = -2, b = 5

C. try your best ill see u later

Step-by-step explanation:

Okay I'mma state some stuff first 3^a + 3^b = 3^(a+b)

and 3^a/3^b = 3^(a-b)

So first equation 3^3*3^-3=3^0

So second equation 3^3/3^-2 = 3^5

So third equation I dont really know the rule but I'mm just plug in a random number for g, like 2, then solve the thing like a normal equation.

So 3^-3 x f^-3 = 12^2 = 144, f^-3 = 144/(3^-3 or 1/27) = 144 x 27 = 3888

so f^-3 = 3888, f = well its an imaginary number according to calculator so u try your best on the last one

Step 1: Define

Identify

[tex]\displaystyle f(x) = \left \{ {{\sqrt{x + 1}, \ x < 3} \atop {5 - x, \ x \geq 3}} \right.[/tex]

Step 2: Find Right Limit

∴ the right-side limit equals 2.

Step 3: Find Left Limit

∴ the left-side limit equals 2.

Step 4: Find Limit

The right and left-side limits are equal.

Answer:

B. y = 2x + 5

Step-by-step explanation:

Slope intercept formula y=mx+b

Slope formula y1-y2/x1-x2

First, let's find slope since we are provided 2 pairs of points, we can simply plug in our numbers in the Slope formula (y1-y2/x1-x2)

5-7/0-1

-2/-1

2/1

=2

Slope (m) = 2

Now using slope let's find our y-intercept (b) to plugin in our slope intercept formula (y=mx+b) for this let's use point 0,5

y=2x+b

5=2(0)+b

5=b

Y-intercept (b) = 5

Now let's plug in the slope (m) and the y-intercept (b) into the slope-intercept formula (y=mx+b)

y=mx+b

y=2x+5

So therefore our answer is B

Answer:

11+m = 15

m = 4

Step-by-step explanation:

Sum means add and is means equals

11+m = 15

Subtract 11 from each side

11+m-11 =15-11

m = 4

Answer: B

Step-by-step explanation: The number line has tally marks up to 3, so 3 has to be divided by something, meaning A and C do not work. There are 9 total tally marks circled, so the equation equals 9, leaving B as the only possible answer. Also, there are three tally marks per whole number, so each tally is 1/3, which is equal to 2/6, further proving it is B.

Answer:

cos 62° = Adjacent / hypochondrium

[tex] \cos 62° = \frac{y}{35} [/tex]

y= cos 62° × 35

y = 16.43

y=16

cos 62° = 16/35
