Angela is helping her father paint a fence. She can paint 3 sections of the fence in 25 minutes. How many minutes will it take Angela to paint 12 sections of this fence? ​

Answers

Answer:

100 Minutes.

Step-by-step explain:

25 divided by 3 = 8.33333333333, So, 8.3 minutes to paint one section at a time. So, 8.3 x 12 = 99.6. So, 99.6 rounded since the last number is higher than 5 it would go to the next number. So, rounded its 100 minutes.  100 minutes for Angela to paint 12 sections.

20 divided 16 in fraction form (simplist form)

Answers

Answer:

1/4

Step-by-step exp

20/16=1.25=1/4

The fraction 20 divided by 16 can be expressed in simplified form as 5/4.

What is 20 divided 16 in fraction form?

To simplify the fraction 20 divided by 16, we need to find the greatest common divisor (GCD) of the numerator (20) and the denominator (16) and divide both by that number. Let's break down the steps:

Step 1: Find the GCD

To find the GCD of 20 and 16, we can use the Euclidean algorithm. We start by dividing 20 by 16, which gives us a quotient of 1 and a remainder of 4. We then divide 16 by 4, resulting in a quotient of 4 and no remainder. The last nonzero remainder obtained is 4, so the GCD of 20 and 16 is 4.

Step 2: Divide by the GCD

To simplify the fraction, we divide both the numerator and denominator by the GCD of 4.

20 ÷ 4 = 5

16 ÷ 4 = 4

So, the simplified fraction is 5/4.

Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different. ... We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily. To combine like terms, we add the coefficients and keep the variables the same

Answer:

A)x^2-x-6

B)2x^2-12x+12

C)x^2-4

Step-by-step explanation:

A) Lets break this problem into portions the first part we trying  to distribute is  x(x-3)

X times X is X^2 and X times 3 is 3x so x^2-3x

Lets work on the second part

2(x-3)

2 times x =2x and 2 times -3 = -6 so 2x-6

And since you are supposed to add them its 2x-6+x^2-3x

x^2 can't be combined so that is seperate but 2x(+)-3x (negative overpowers positiveis) so we have -x and then -6 cant be joined with anything so

x^2-x-6

B) I'm going to go a little faster but it's essentially the same

2x(x-4)-3(x-4)

Multiply2x*x= 2x^2

2x*-4=-8x

combinde these two (2x^2-8x)

Pt.2

-3*x= -3x

-3*-4(negative and negative cancels out and it becomes positive)=12

join  (-3x+12)

and then 2x^2-8x-3x+12

you can only combine -8x-3x so -12x

2x^2-12x+12

C) this is level 3

x(x-2) + 2(x-2)

(x^2-2x) +(2x-4)

only like terms is 2x and-2x so combine and its 0

x^2-4

The quotient of a number g and -4 is at most 5 .

Answers

Answer:

g≥-20

Step-by-step explanation:

The quotient of a number g and -4 is expressed as;

g/-4

If the quotient of a number g and -4 is at most 5, this is expressed as;

g/-4 ≤ 5

Multiply both sides by -4

g/-4 * -4 ≤ 5 * -4

g *  ≥ -20

Hence the required solution is g≥-20

Step-by-step explanation:

I just did it on edge and got it correct

The value of y is 6 centimeters.

Given that,

The length of RU = 12 centimeters

The length of UT = 4 centimeters

The length of QU = 8 centimeters.

The length of US = y centimeters

What is the intersecting chords theorem?

The intersecting chords theorem states that, the product of one whole chords segment and its external segment is equal to the product of the other whole chords segment and its external segment when two chords cross at an exterior point.

According to the intersecting chords theorem,

US x QU = RU x UT

Substitute the values in above formula,

y x 8 = 12 x 4

y = 48/8

y = 6 centimeters,

Hence, the value of y is 6 centimeters.

Step-by-step explanation:

oh law of sines   soo  sin(A) / a = Sin(B) / b

2a)

here DE = side f   then let's find that side with law of sines and plug side f in as 'a' in law of sines , so

Sin(28) / a = Sin(54) / 31  ( where a = f = DE )

can you do the algebra here Emily?  or do you want me to show that?

Sin(28) *31 / Sin(54) = a

17.989 =a

18.0 =a       (rounded to nearest 10th)

DE = 18.0 m

2b)

find RT  where RT = side a

since they give use 2 of the other sides of the triangle we can quickly figure out the S angle.   180 = 71+62+S   so  S = 47°  ( I'm going kinda fast b/c I don't know how much time you have  :? )

then Sin(A) /a = Sin(B) / b

Sin(47) / a = Sin(62) / 29

Sin(47) *29 / Sin(62) = a

24.020 = a

RT = 24.0 meters  ( rounded to nearest 10th )

2c)

they want us to find ∠X with law of sines soo

I'll just use the letter they give us for variables

Sin(X) / x  = Sin(Y ) / y

Sin(X) = x* Sin(y) / y

X = arcSin [ 14 * Sin(108) / 34 ]

X = arcSin [ 0.3916115]

X = 23.0548°

X= 23°  ( rounded to nearest degree )

2d)

they ask us to find ∠E

I'll , again, use the letter they give us for variables

Sin(E) / e = Sin( F ) / f

Sin(E) / 18 = Sin(78) / 30

E = arcSin[ 18 * Sin(78) / 30 ]

E = arcSin [ 0.5868856 ]

E = 35.936 °

E = 36 °    ( rounded to nearest degree )

Answers

24 months is the correct answer

Damian will be charged interest for 24 months.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We are given that Damian took out a car loan for $10,500 that has a 0% APR for the first 12 months and will be paid off with monthly payments over 3 years.

We know that;

1 year = 12 months

Using this conversion we get;

3 year = 36 months

It means total number of months in 3 years is 36. For first 24 months the APR is 0%. So, the number of months will Damian be charged interest is

36 - 12 = 24

Therefore, the correct option is D. 24 months
