Answer:

1. 9/2

2. 7 3/13

3. 3 13/15

4. 3 25/27

5. 2 1/4

6. 3 30/91

7. 2 5/21

8. 6 3/5

Step-by-step explanation:

When I put it like 2 5/21 I mean it's a mixed number.

Now I'll tell you the steps.

1. Find the common denominator (The denominator is the bottom number of the fraction. To find it you have to write out the multiplies of each number and once a number is the same that's the common denominator.)

2. Multiply the numerator by the amount of times it took to find the common denominator. (The numerator is the top number of the fraction. And the amount of times you'll have to multiply the numerator depends. I'll put an example below)

Example:

4/20 ÷ 7/2

2 goes into 20, 10 times so you have to multiply 7 by 10.

Then you'll get

70/20.

Now you can solve it.

4/20÷70/20

(I put random numbers so the answer may turn out funky this is just an example.)

3. Divide the fractions

4. Simplify answer if possible

Answer:

-6 ≤ x ≤ ∨ x = 4

Step-by-step explanation:

x^2 + 2·x ≤ 24

x^2 + 2·x - 24 ≤ 0

-1 - √(1 + 24) ≤ x ≤ -1 + √(1 + 24)

-1 - 5 ≤ x ≤ -1 + 5

-6 ≤ x ≤ ∨ x = 4

Considering the table of f ( x ) and graph of g ( x ), the value of the expression  [tex]\lim_{x \to 1} 2f(x)+g(x)^2[/tex] is represented by 3

The table represents the values of f ( x ). Using the table, checking the value of f ( x ) when x = 1 gives f ( x ) = 1

Using the graph, the value of g ( x ) when x = 1 is traced to give a value of -1

substituting the values of f ( x ) = 1 and g ( x ) = -1  into the equation

[tex]\lim_{x \to 1} 2f(x)+g(x)^2[/tex]

[tex]=\lim_{x \to 1} 2f(1)+g(1)^2[/tex]

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

= 2 + 1

= 3

This makes the third option the best choice and the value is 3

The equation of the line will be expressed as x = 5.

Slope of a line may be defined as the steepness of a curve plotted on paper. The slope of a line between two points (x₁, y₁) and (x₂, y₂) can be calculated by formula m = (y₂ - y₁)/(x₂ - x₁).

If we have two points and we have to find equation of line through two points (x₁, y₁) then equation will be (y - y₁) = m(x - x₁) where m is the slope of line.

We have two points (5, 3) and slope is undefined.

Undefined slope can be expressed as 1/0. So, the equation of line through (5, 3) will be

(y - 3) = 1/0 (x - 5)

=> x - 5 =0

=> x = 5

This is the equation of line, and this line will be parallel to y-axis.

The ratio of the number of students who want waffles to the total number of students is 3 : 26 students

Ratio refers to the number representing a comparison between two named things or quantities.

Number of students who wants waffles = Total number of students - Number of students who wants pancakes

= 26 students - 23 students

= 3 students

Ratio of the number of students who want waffles to the total number of students = 3 students : 26 students

So therefore, the ratio of the number of students who want waffles to the total number of students separated by a colon is 3 : 26

Line's equation is y=(1/5)x + 2.

In elementary geometry, two geometrical objects are perpendicular if they intersect at a right angle. The condition of perpendicularity can be graphically represented using the perpendicular symbol,. Any pair of lines, any pair of planes, or any pair of lines and planes can be used to define it.

The arrow

In slope-intercept form, y=-5x12

y=mx+b

where the slope m is.

Thus, the slope of this line is

m= -5

Slopes on perpendicular lines are reciprocally negative. In other words, modify the sign by taking the slope's reciprocal.

The reciprocal of (-5) in the negative is 1/5.

Plug in the point to determine b in the formula y = (1/5)x + b.

4 = (1/5)(10) + b

4 = 2 + b

b = 2

The perpendicular line passing through the indicated point is y= (1/5)x + 2.

Thus, the equation of the line that is perpendicular to the line y = -5x - 12 and passes through the point is y= (1/5)x + 2.

The largest number of weights Jennifer could own is 798.

Repeated addition of the same number is made easier by multiplying the numbers. When we need to merge groups of similar sizes, we employ it. For instance, if there are 5 baskets, each containing 4 apples, we can use multiplication to get the total number of apples, which is 5 x 4 = 20 apples.

We can rapidly determine the total number of things by multiplying. When multiplying, we'll consider the number of groups with similar sizes and the number of items in each group.

Given: The collection of weights : 4 , 6 and 9 pounds

The total weight of the weights = 42 pounds

Thus the largest number of weights jennifer could own is 4+6+9 = 19 multiplied  by the total weight of the weights

= 19 × 42

The probability that at least one of them will score a goal if they each play the ball once is 47/48.

Probability is a mathematical and scientific term that describes the possibility or occurrence of an event. Many events are difficult to predict with absolute accuracy. Only the likelihood of an event occurring, i.e. how likely it is, can be predicted using probability.

Given:

The probabilities of Wukong and Nice scoring in the match are 7/8 and 5/6 respectively.

The probability that at least one of them will score a goal is,

=  1 - P(both of them not scoring a goal)

So the probability of Wukong and Nice not scoring a goal in the match is,

(1 - 7/8) (1 - 5/6) =  (1/8)(1/6) = 1/48

Now the required probability is,

If after one year, she received a total of $620 in interest.  The amount that she invest in each account is 2,000 amount invested at 7% , 8,000 amount invested at 6.

Let x represent the amount invested

Hence,

.07x + .06(10,000-x) =620

.07X+600-.06x = 620

Combine like terms

.01x =620-600

.01x=20

Divide both side by .01x

x=20/.01

x =2,000 amount invested at 7%

So,

10,000-2,000 = 8,000 amount invested at 6%

Check :

.07 × 2,000+.06× 8,000=620

150 + 480 = 620
