Mr Chin bought 3.8 kg of candy, nearest to
100g. What is the least amount of candy in the
bag to nearest kilogram.

Answers

To do this you need to find the lower bound
The lower bound is the minimum amount that would round up to the estimated value

3.8kg, measured to the nearest 100g
The degree of accuracy is to the nearest 100g
100/2 = 50g (0.05kg)

Lower bound 3.8 - 0.05 = 3.75kg

Therefore the least amount of candy you could have in the bag is 3.75kg

If you randomly select a card from a well-shuffled standard deck of 52 cards, what is the probability that the card you select is not a 4? (Your answer must be in the form of a reduced fraction.)

Answers

Answer:

12/13

Step-by-step explanation:

A standard deck of cards has four suites

Total number of cards = 52

Total number of cards which are 4 is = 4

The probability that the card selected is 4 = 4/52 = 1/13

S,  the probability that the selected card is not a 4 = 1 - (1/13 )= 12/13

Shane and abha earned a team budget that required their team to collect no less than 2000 cans for recycling. Abha collected 178 more cans than Shane did. Write an inequality to determine the number of cans , s, that Shane could have collected

Answers

Answer:

s ≥ 911

Step-by-step explanation:

Let

s = number of cans Shane could collect

Abha collected 178 more cans than Shane did.

Abha = s + 178

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling

Number of cans collected by Shane + number of cans collected by Abha ≥ 2000

s + 178 + s ≥ 2000

2s + 178 ≥ 2000

2s ≥ 2000 - 178

2s ≥ 1,822

Divide both sides by 2

s ≥ 1,822 / 2

s ≥ 911

11) Which of the following is zero of the polynomial x^3+x^2+x+1

1
-1
both options 1 and 2
None
please answer​

Answers

Answer:

Answer: -1

Step-by-step explanation:

The Polynomial Remainder Theorem

It states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).

We have the polynomial:

[tex]f(x)=x^3+x^2+x+1[/tex]

And we need to determine if x=1 and/or x=-1 are zeros of the polynomial.

Considering the polynomial remainder theorem, if we try any value for x, and the remainder is zero, then that value of x is a root or zero of the polynomial.

Find:

[tex]f(1)=1^3+1^2+1+1[/tex]

f(1)=4

Thus, x=1 is not a zero of f(x)

Now, find:

[tex]f(-1)=(-1)^3+(-1)^2+(-1)+1[/tex]

[tex]f(1)=-1+1-1+1=0[/tex]

Thus, x=-1 is a zero of f(x)

Given: 4d=1/3(c-d) Proof= c=13d

Answers

Proof:

Multiply both of the sides by 3. You would get 12d = c - d. Add d on both sides, and you would get c = 12d

Here, we are required to proof c = 13d from 4d=1/3(c-d)

Ultimately, c = 13d (proof)

We have;

4d=1/3(c-d)

Cross product

4d × 3 = c - d

therefore, By collecting like terms;

C = 12d +d

and Ultimately, c = 13d ......

Answers

Change -3y + 12 = -8x to the form y = mx + b

Subtract 12 on both sides

-3y = -8x - 12

Divide by -3 on both sides

y = 8/3 + 4


Change original equation to Ax + By = C

-3y + 12 = -8x

Switch -8x and 12

The area of this figure is 80 square units.


Write an equation for the area of the shape below.

Answers

Answer:

Step-by-step explanation:

A = 12 × 16 + (1/2)(12 + 8)(10) = 292 units²

The Equation for Area of figure is area of Figure, h² + 1/2(h)(b) = 80

What is Area?

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Given:

We have the figure consist of one rectangle and one right triangle.

Now, Area of Figure,

=Area of rectangle + area of Triangle

= length x width + / x base x height

=  16 x 12 + 1/2 x 10 x 20

= 192+ 100

=292 unit²

and, if the square with height, h, units and a right triangle with height, h units, and a base length, b units.

Then, area of Figure= h² + 1/2(h)(b) = 80 square units.
