How do you convert 10/6 into a mixed number

Answers

Well, First you want to find out how many times six can go into ten. Since its only once, you immediately get the number 1 as your whole number. Now because you've taken six out of ten you're left with 4/6. The mixed number would be 1 and 4/6 or 1 and 2/3 if you're simplifying
Hi. To convert 10/6 into a decimal, you simply divide the bottom into the top. In this case, it would be 10 ÷ 6.

6 can go into 10 1 time and will have a remainder of 4. You bring the 4 up and place the 6 under it. This will give you the mixed number of 1 4/6 which can be reduced to 1 2/3

See the attached for a visual. Hope this helps. If you have further questions, please don't hesitate to ask.

Take care,

If s is true and j is false, is the following true or false (~s v j) ^ (s v~ j)

Answers

s = true
~s = false
-------------
j = false
~j = true
-------------
~s = false and j = false, so,
~s v j = (false) v (false)
~s v j = false
-------------
Similarly,
s v ~j = (true) v (true)
s v ~j = true
-------------
We have 
~s v j = false
and 
s v ~j = true
which lead to this when we conjunct the two logical expressions
(~s v j) ^ (s v ~j) = (false) ^ (true)
(~s v j) ^ (s v ~j) = false
-------------
-------------
The final answer is false

how do you write S is the set of natural numbers that are less than 8 in roster form

Answers

In mathematics, the roster form is when we call a group of set members that is placed inside between brackets, and is separated by commas. So in this case, natural numbers which are less than 8 are 1 to 7, hence the roster form is:

Bryce and Rachel are collecting canned goods for the local food bank. Bryce's goal is to collect 32 items. Rachel's goal is to collect 24 items. If Rachel and Bryce each meet their goal, what fraction of Bryce's goal does Rachel collect?

Answers

I think the fraction would be 3/4.

Rachel collects 3/4 or 75% of Bryce's goal if they both meet their goals in the canned goods drive

The question involves determining what fraction of Bryce's goal Rachel collects if they both meet their personal goals for a canned goods drive. Bryce's goal is to collect 32 items, and Rachel's goal is to collect 24 items. To find the fraction of Bryce's goal that Rachel collects, you divide Rachel's goal by Bryce's goal.

Here's the calculation:

Rachel's collection / Bryce's collection = 24 / 32 = 3/4

This means that Rachel collects 3/4 or 75% of the number of items that Bryce collects

what is the area of the figure?

Answers

Notice that the triangle is a right isosceles triangle, because the given angle measures are 45° and 90°, so the third angle measure is 180°-90°-45°=45°.

The length of the hypotenuse is 24 ft. Let the side lengths of the 2 equal sides be a.


By the Pythagorean theorem we have:

[tex]a^2+a^2=24^2[/tex]

thus

[tex]2a^2=24^2[/tex]

divide both sides by 2, and take the square root:

[tex]a= \frac{24}{ \sqrt{2} } = \frac{24 \sqrt{2} }{2}=12 \sqrt{2} [/tex]


The area of the triangle is given by the formula:

(1/2)*side*side, so the area of the triangle is :


(1/2)*[tex]12 \sqrt{2}[/tex]*[tex]12 \sqrt{2}[/tex]=144 (square units)


Answer: 144 square units

solve the system by graphing y=2x^2+3x+1. Y=2x+1

Answers

the solution to the system of equations by graphing is [tex]\( (0,1), (-5/2,6) \)[/tex]

The correct option is (C).

The generated image above represents a graphical solution to the system of equations given:

[tex]\[ y = 2x^2 + 3x + 1 \][/tex]

[tex]\[ y = -2x + 1 \][/tex]

However, the graph does not clearly show the exact points of intersection between the parabola and the line. To find the solutions accurately, we would typically set the two equations equal to each other and solve for [tex]\( x \)[/tex]:

[tex]\[ 2x^2 + 3x + 1 = -2x + 1 \][/tex]

Solving this equation algebraically will give us the [tex]\( x \)[/tex]-coordinates of the points of intersection. The corresponding [tex]\( y \)[/tex]-values can then be found by substituting these [tex]\( x \)[/tex]-values back into either of the original equations.

Since I cannot perform this algebraic computation at the moment, you can solve the equation using the following steps:

1. Move all terms to one side of the equation to set it to zero.

2. Solve the resulting quadratic equation, either by factoring, completing the square, or using the quadratic formula.

3. Substitute the [tex]\( x \)[/tex]-values back into one of the original equations to find the [tex]\( y \)[/tex]-values.

Therefore, the correct option that represents the solution to the system of equations by graphing is:

Suppose the Willard gold nugget was turned into 4 equal sized gold bricks. If one of the bricks was sold how many ounces of the Willard nugget would be left?

Answers

788/4= 197; 197 ounces for each golden brick. 

---- 197x4= 788 so if 197 oz was sold then 788-197= 591oz.

 > There would only be 591 oz left

The number of ounces left after one brick is sold is 591.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Willard gold nuggets = 788 ounces

The number of equal-sized bricks = 4

Now,

The number of ounces in each of the 4 bricks.

= 788/4

= 197 ounces

Number of bricks sold = 1

The remaining ounces.

= 788 - 197

= 591 ounces

Thus,

The number of ounces left is 591.

Answers

Lot One:
15 divided by 36 = 0.4166  convert to % by moving the decimal two places to the right.  round if needed. 
Lot One = 41.66 %

Lot Two:
43 divided by 92 = 0.4673
Lot One = 46.73 %

Lot Three:
12 divided by 30 = 0.4
Lot Three = 40%

Lot Four:
32 divided by 52 = 0.6153
Lot Four = 61.53 %

Lot Four had the greatest % of Blue cars.

The percentage of blue cars in the lot is the ratio of the number of blue cars to the total number of cars in each lot ; Hence, lot D has the greatest percentage of blue cars

Percentage of blue cars in each lot :

Number of Blue cars / total number of cars

Lot A :

% blue cars = 15 / 36 = 0.4167

Lot B :

% blue cars = 43 / 92 = 0.4673

Lot C :

% blue cars = 12 / 30 = 0.40

Lot D :

% blue cars = 32 / 52 = 0.615

Therefore, lot D has the greatest percentage of blue cars.

A 32 mb memory stick can hold up to 491 images. How many images can 7 memory sticks hold?

Answers

7 memory sticks at 32 mb can hold 491 * 7 = 3437 images.
Final answer:

To find out how many images 7 memory sticks can hold, multiply the number of images one memory stick can hold by the number of memory sticks.

Explanation:

To find out how many images 7 memory sticks can hold, we need to multiply the number of images one memory stick can hold by the number of memory sticks. In this case, each memory stick can hold 491 images, so to find out how many images 7 memory sticks can hold, we calculate:

Number of images = Number of memory sticks × Number of images per memory stick = 7 × 491 = 3437 images

Therefore, 7 memory sticks can hold 3437 images.

Eight members of the Math club equally shared three pizzas. Expressed as a fraction,whAt part of a pizza did each member receive ?

Answers

3/8 of a pizza.

If you divide each pizza into eight parts, each member would receive 1/8 of one pizza. Since there are three pizzas, each member would receive three 1/8 of a pizza, or 3/8.

You can prove this answer by multiplying 3/8 by 8, to get 24/8 simplified to 3.

Answer: 5ft - 7.2ft +2.2 ft = 0

When he finishes the trick he will be in the starting point.

Step-by-step explanation:

Hi, to write the expression we have to analyze the information given:

Forward: 5 feet Backwards: 7.2 feet Forward: 2.2 feet

So, we simply have to sum the tricks that takes him forward and subtract the tricks that take him backwards.

Mathematically speaking:

5ft - 7.2ft +2.2 ft = 0

When he finishes the trick he will be in the starting point, because the expression equals 0.
