Find the area of this circle.
Use 3.14 to approximate .
A = ar2
14 ft
A = [ ? ] ft?

Answer:

63+22i

Step-by-step explanation:

(8 - 3i)(6 + 5i)

FOIL

first: 8*6 = 48

outer: 8*5i = 40i

inner: -3i* 6 = -18i

last: -3i*5i = -15 i^2 = -15(-1) = 15

Add together

48+40i -18i +15

Combine like terms

63+22i

Answer:

You will save $20.

Step-by-step explanation:

IMPORTANT FORMULA: TO CONVERT A NUMBER TO A PERCENT, YOU HAVE TO MULTIPLY BY 100. TO CONVERT A PERCENT TO A NUMBER, YOU HAVE TO DIVIDE BY 100.

1) Some percent of an amount is what?  

Using the formula above, I can conclude that 40% is equal to 40/100=4/10=2/5

2) Translate into an equation.

It is important to keep in mind that we are trying to find 40% of $50 in order to find out how much money will be saved.

In the above step, we already found that 40% = 2/5.

I also know that, in mathematics, the word "of" means multiplication.

Therefore, I am trying to find 40% of $50 is the same as 2/5 * $50.

2/5 * $50 = x    ------ (x represents the money saved)

3) Solve for variable.

$20 = x

4) Write a sentence to answer the question.

You will save $20.

Answer:

Step-by-step explanation:

An exponent or index is a number or letter written above and to the right of a mathematical expression called the base.

It indicates that the base is to be raised to a certain power.

Here,

3, 4 and 12 are the letters which are written above the base 2.

So,

3, 4 and 12 are exponent or index

Answer:

C. g(x) = 4x²

Step-by-step explanation:

we have one specific point on g(x) : (1,4)

so, for x=1 the functional value (y) has to be 4.

A. (4×1)² = 4² = 16 and not 4. => wrong

B. 1/4 × 1² = 1/4 and not 4. => wrong

C. 4×1² = 4 and that IS 4 => correct

D. 16×1² = 16 and not 4 => wrong

Answer:

653 is the total suface area

Step-by-step explanation:

i have all the math in the note book but i can explain it very simply you find the area of the big base which is 120 the side of 12 which equals 84 and the side of ten which equals 70 and multiply them all by two which gives you 548 then you multiply the base of the small figure (only count one of the shapes bases btw) and that equals 9 the you find the sides which are 24 each this gives you 96 + 548 = 644 +9 = 653 and there is your answer

Answer:

644in~2

Step-by-step explanation:

acellus 2022 ;)

Answer:

The ratios are 15 18 and 17 which total 50

So one person will receive 15/50 = 30 per cent

Another person receives 18/50 = 36 per cent

The third person receives 17/50 = 34 per cent

1st Person  30% of 3,990 = 1,197.00

2nd Person  36% of 3,990 = 1,436.40

3rd Person   34% of 3,990 = 1,356.60

Step-by-step explanation:

Answer:

$1197 : $1436.4 : $1356.6

Step-by-step explanation:

15 + 18 + 17 = 50

3990 / 50 = 79.8

1st person : 79.8 x 15 = 1197

2nd person : 79.8 x 18 = 1436.4

3rd person : 79.8 x 17 = 1356.6

$1197 : $1436.4 : $1356.6

Answer:

yes both lines have a slope of 2, so they are parallel.

Answer: (5, 0) and (3, 4)

Answer:

x=15 y=24

Step-by-step explanation:

This is because the rule is x goes up 3 y goes up 4

(9,12)->(x,20)

it skips one, so instead of adding 3 we add six

x=15

(15,20)->(18,y)

you follow the rule and 4.

Y=24

Answer:

The common difference is definitely 3. The common difference is the difference between the numbers in a sequence. In the sequence 3,6,9,12, and 15 the common difference is 3.

Answer:

-15

Step-by-step explanation:

Step 1: Multiply 3 by both sides

3(2/3x)=3(-10)

Step 2: Simplify

2x=-30

Step 3: Divide both sides by 2

2x/2=-30/2

Step 4: Simplify

x=-15

Answer:

  (b) Line SW has an undefined slope.

  (c) Line TV has a slope of 0.

  (d) Lines RS and TV are parallel.

Step-by-step explanation:

A horizontal line has 0 slope. Lines RS and TV are horizontal, hence are parallel and have 0 slope.

A vertical line has undefined slope. Line SW is vertical, hence has undefined slope.

Answer:

C; 500%

Step-by-step explanation:

To get the percentage, we need to make a straight division, then multiply by 100%

We have this as;

(4.5 * 10^5)/(9 * 10^4) * 100%

= 5 * 100% = 500%
