Answer:

After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25

Step-by-step explanation:

The given expression is:[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex]

First I solve the expression, and then will point the error

[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)\\Converting \ \div \ sign \ into \ \times the \ term \ is \ inverted\\=0.38 \times 3 \times(-20)\times5\times(-1/8)\\=0.38\times 3 \times-20\times5\times-1/8\\=1.14 \times-20\times5\times-1/8\\=-22.8\times5\times-1/8\\=-114\times-1/8\\=\frac{-114}{-8}\\=14.25[/tex]

So, the mistake Mia did was when she inverted division sign into multiplication, she didn't invert the term next to division sign.

The step she did was: [tex]0.38 \times 5 \times(1/20)\times3\times(-8)[/tex]

While the correct step was: [tex]0.38 \times 3 \times(-20)\times5\times(-1/8)[/tex]

After correcting error of Mia and solving the expression[tex]0.38 \times 3 \div(-1/20)\times5\div(-8)[/tex] we get 14.25

There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter.
To the nearest inch, how many inches are in 13 meters? Enter the answer in the box.
inches

Answers

Answer:

Answer: 512 inches

Step-by-step explanation:

Unit Conversion

We need to recall two basic unit conversions for length:

1 inch = 2.54 cm

1 meter = 100 cm

We are given a length of 13 meters. Converting to centimeters:

13 * 100 = 1300 cm

Now convert to inches dividing by 2.54:

[tex]1300 / 2.54 \approx 512[/tex]

Step-by-step explanation:

130 - y = 224

subtract 130 from both sides

130 - 130 - y = 224 - 130

-y = 94

if the solutions of p(x)=0 are -14 and 11, which function could be p?
(A) p(x)=x^2-3x-154

(B) p(x)=x^2-14x+11

(C) p(x)=x^2+14x+11

(D) p(x)=x^2+3x-154

Answers

Answer:d

Step-by-step explanation:

The required function is [tex]P(x)=x^2+3x+154[/tex]. So, option D is correct.

Important information:

The solutions of [tex]p(x)=0[/tex] are [tex]-14[/tex] and 11.

We need to find the function p(x).

Function:

If [tex]x=c[/tex] is a solution of [tex]p(x)=0[/tex], then [tex](x-c)[/tex] is a factor of p(x).

It means [tex](x+14)[/tex] and [tex](x-11)[/tex] are two factor of p(x).

[tex]P(x)=(x+14)(x-11)[/tex]

[tex]P(x)=x^2-11x+14x+154[/tex]

[tex]P(x)=x^2+3x+154[/tex]

Therefore, the correct option is D.

A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t^2+64t+80 gives the height, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?

I already found the maximum height, it's at 144 feet

A. 5

B. 16

C. 2

D. 9

Answers

Answer:

5 seccs

Step-by-step explanation:

Given the modeled function of the height expressed as;

h(t)=-16t^2+64t+80

The ball hits the ground when h(t) = 0 (when the height is zero)

Substitute into the function and find t;

0 =-16t^2+64t+80

divide through by -16

0 = t²-4t-5

Factorize;

t²-4t-5 = 0

t²-5t+t-5 = 0

t(t-5)+1(t-5) = 0

(t+1)(t-5) = 0

t + 1 = 0 and t-5 = 0

t = -1 and t = 5

Time can't be negative

Hence it will take the ball 5secs before it hits the ground

Step-by-step explanation:

Take out an x from everything. Numbers that have powers will just go down a power (ex- 3x^4 would go to 3x^3) and if you have just an x then it turns into one.

The polynomial by the division is equal to [tex]3x^3-6x-1[/tex]

What is a polynomial?

They are mathematical expressions involving variables raised with non negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non negative exponentiation of variables involved.

We are given the polynomial

[tex]3x^4-6x^2-x/x[/tex]

We need to divide the polynomial by x.

[tex]3x^4-6x^2-x/x[/tex]

Then we need to factor out x

100 products

Step-by-step explanation:

Jessica earns 2,000 per month as a sales woman

In addition to the salary she earns 80 per product that she sells

Her goal is to earn 10,000 per month

Therefore the number of products that will be sold to attain 10,000 can be calculated as follows

= 80×100

= 8,000

= 8,000+2,000= 10,000

The perimeter of a kite is 50 mm. The length of one of its sides is 1 mm more than twice the length of another. Find the length of the LONGEST side of the kite. Only write the value of the longest side.

Answers

Answer:

The length of the longest side is 13mm

Step-by-step explanation:

Represent the two sides with a and b, where a is the longest

[tex]Perimeter = 50[/tex]

[tex]a=b + 1[/tex]

Required

Determine the length of the longest side

Perimeter of a kite is calculated as thus:

[tex]Perimeter = 2(a + b)[/tex]

Make b the subject in [tex]a=b + 1[/tex]

[tex]b = a -1[/tex]

Substitute a - 1 for b and 50 for Perimeter in [tex]Perimeter = 2(a + b)[/tex]

[tex]50 = 2(a + a - 1)[/tex]

Divide through by 2

[tex]25 = a + a - 1[/tex]

[tex]25 = 2a- 1[/tex]

Add 1 to both sides

[tex]25 + 1 = 2a - 1 +1[/tex]

[tex]25 + 1 = 2a[/tex]

[tex]26 = 2a[/tex]

Solve for a

[tex]a = 26/2[/tex]

[tex]a = 13[/tex]

Hence, the length of the longest side is 13mm
