What is the radical form of the expression? (5x3y4)37

Answer:

15 pounds

Step-by-step explanation:

Kevin is making potato casserole for a dinner party. He needs 2½ pounds of potatoes per guest. How many pounds of potatoes will he need for 6 guests?

15 pounds

6.5 pounds  

25 pounds

12.5 pounds

2.5lb × 6 guest = 15 pounds

Answer: 15 pounds of potatoes.

Step-by-step explanation:

Kevin will perform basic multiplication to find how many potatoes he needs for all of the guests. Since each person requires 2 1/2 pound of potatoes and there are a total of 6 guests, multiplying these two values will find the pounds of potatoes that are needed for all of the guests.

2 1/2 * 6 = 15 pounds of potatoes

Therefore, Kevin needs 15 pounds of potatoes to make potato casserole for everyone at the dinner party.

The area of the triangle in the image is 10 square units, thus, option C is the correct one.

For a triangle of height H and a base B, the area is given by:

A = H*B/2.

In the image we can see that the base of the triangle goes from (0, 0) to (5, 0), then the length of the base is 5 units.

While the height goes from (0, 0) to (0, 4), so the height is 4 units.

Then the area will be:

A = (4 units)*(5 units)/2 = (20 square units)/2 = 10 square units.

The area is 10 square units.

Answer: No, this is not a function.

Functions exist when there are a unique set of x-values and each can match with a y-value. There cannot be a repeating x-value because this creates a discontinuity in the graph. You can have as many repeating y-values as you’d like as long as they each have a unique x-value and are not duplicate plot points.

Since x = 7 repeats in the domain of x-values, this cannot be a function.

The percent increase in her salary resulted from her promotion is 6.67%.

The annual salary of Marisol as an engineer = $75000.

After, the promotion salary of Marisol as an engineer = $80000.

We have to find the increment in her salary after promotion in percentage.

Before finding the increment in percentage we find the total increment in dollar in her salary after promotion.

Total increment in dollar = Salary after Promotion − Salary before Promotion

Total increment in dollar = $80,000 − $75,000

Total increment in dollar = $5000

As we know that we can find the percentage by multiplying the required number by 100 because percentage is the ratio with 100.

So, the increment in salary after promotion in percentage.

% increment = (Total increment/Salary before) * 100

% increment [tex]= (\frac{5000}{75000})*100[/tex]

% increment = 0.0667 * 100

% increment = 6.67%

Now we see that percent increase in her salary resulted from her promotion is 6.67%.

Answer:

Step-by-step explanation:

Answer:

x = 6 cm

Step-by-step explanation:

The two shapes are similar. That means one figure is exactly a multiple of the other figure

We can see that the ration of the length of the bigger rectangle  to the length of the smaller rectangle is 15/9 = 5/3  

Therefore the ratio of the width of the bigger rectangle  to the width of the smaller rectangle must also be 5/3

Given width of big rectangle = 10 and that of small rectangle is x

We get

10/x = 5/3

Multiply by x both sides:
x ×   10/x   =   x × 5/3

10 = 5x/3

Multiply by 3 both sides

30 = 5x

5x = 30

Dividing by 5 both sides
5x/x = 30/5
x = 6 cm

From the inequality concept ( -7 / 10) > ( -5 / 6).

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.

Given fractional numbers are -5/6 and -7/10. The numbers in the form of inequality will be calculated as:-

-7 / 10 = -0.7

-5 / 6 = -0.84

-0.7 > -0.84

-7 / 10 > -5 / 6

The function which has a graph with the largest positive x-intercept is C. f(x) = 2(x-8) +1

The value of the x coordinate at the point where the graph crosses the x-axis is known as the x-intercept for any curve. Alternatively, we can say that the x-intercept is the value of the x coordinate at the point where the value of the y coordinate equals zero.

Let y be 0, so lets find the x-intercept of

The equation of the line parallel to the given line that contains C is obtained as y = x + 6.

For the given question;

The equation of the line is given as;

y = x + 4

The standard form of the equation of line in slope intercept form is;

y = m x + c

where, m is the slope and c is the y intercept.

On comparing;

m₁ = 1

Now, the other lien is parallel to the given line.

Thus, slopes of both lines will be equal.

m₁ = m₂ = 1

The passing points of the line are;

(x₁, y₁) = C(1, 7)

Now, the equation of lien will be;

y - y₁ = m₂(x - x₁)

Put the values;

y - 7 = 1(x - 1)

Simplifying.

y = x + 6

Thus, the equation of the line parallel to the given line that contains C is obtained as y = x + 6.

==========================================================

Explanation:

The given translation rule is (x, y) → (x+8, y - 3) which says "shift 8 units right and 3 units down".

The inverse transformation will undo each to get "8 units left and 3 units up"

So the inverse is (x, y) → (x-8, y + 3)

Use this inverse to determine the preimage of point T'(2,-6)

[tex](\text{x},\text{y})\to(\text{x}-8,\text{y}+3)\\\\(2,-6)\to(2-8,-6+3)\\\\(2,-6)\to(-6,-3)\\\\[/tex]

Therefore, preimage point T is located at (-6,-3) which points us to answer choice B

If we were to apply the rule of "shift 8 units right and 3 units down" to T(-6,-3), you should arrive at T'(2,-6)

The number line that correctly compares √24 and 4.256 is number line C.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

This ultimately implies that, a number line can be used for the comparison of two or more numbers such as √24 and 4.256. Also, a number line typically decreases in numerical value towards the left and increases in numerical value towards the right.

Taking the square root of √24, we have:

√24 = 4.899

In this context, we can reasonably and logically deduce that 4.899 is greater than 4.256 (4.899 > 4.256) and would be placed at the right hand side of the number line and further from 4.899 as shown in number line C in the image attached below.
