The inequality Kailyn can use to ensure that she completes at least 25 minutes of Mindplay each day over 4 days to complete a total of 100 minutes is x ≥ 25.

What is inequality ?

An inequality is a mathematical statement that compares two values or expressions using an inequality symbol such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).

To split the 100 minutes evenly over 4 days, Kailyn would need to complete at least 25 minutes each day.

To express this mathematically as an inequality, you can use the greater than or equal to symbol (≥) to indicate that Kailyn must complete at least 25 minutes each day:

Let x be the number of minutes Kailyn completes each day. Then the inequality would be:

x ≥ 25

This means that Kailyn must complete at least 25 minutes of Mindplay each day to ensure that she completes all 100 minutes in the given 4 days.

Therefore, the inequality Kailyn can use to ensure that she completes at least 25 minutes of Mindplay each day over 4 days to complete a total of 100 minutes is x ≥ 25.

The true statement of the equation 4+-2=5 is false

From the question, we have the following parameters that can be used in our computation:

4+-2=5

To determine the trie statement, we evaluate the expression 4 + (-2)

Using the above as a guide, we have the following:

The sum of 4 and -2 is:

4 + (-2) = 2

By converting the equation 3x - y = 7 in the slope-intercept form, the slope, and the intercept will be (A) m = 3, b = -7.

When you know the slope of the line to be investigated and the given point is also the y-intercept, you can utilize the slope-intercept formula, y = mx + b. (0, b).

The y value of the y-intercept point is denoted by the symbol b in the formula.

A line's slope and y-intercept are expressed in the following formula: y=mx+b.

The y-intercept, which is usually represented in coordinate form as (0,b), is the point where the line crosses the y-axis.

So, we have the equation:

3x - y = 7

After reading the above-given description about the slope-intercept form, we can tell that in the given equation:
m = 3, b = -7

Therefore, by converting the equation 3x - y = 7 in the slope-intercept form, the slope and the intercept will be (A) m = 3, b = -7.

There for the answer is the volume of the pyramid is equal to V = 1/3 (n³ - n²).

What do math lengths mean?

The measurement or size of a thing end to end is referred to as its length. In other words, it is the larger of an object's upper two or three geometric dimensions. The dimensions of a rectangle, for instance, are its length and width.

We know that.

The volume of pyramid is equal to

V =1/3 (area of base) × height

The two functions have equivalent zeros if k = 60.

Here we have two functions which are:

f(x) = 4x - 20

g(x) = -12x + k

We want these two functions to have equivalent zeros, so first let's find the zero of f(x), we will get:

f(x) = 4x - 20 =0

4x  = 20

x = 20/4

x = 5

And that must also be a zero of g(x), then:

-12*5 + k = 0

-60 + k = 0

k = 60

The width of the rectangle cannot be negative, we discard the negative solution and conclude that the width of the rectangle is 4 inches.

What is Area of rectangle ?
Area of rectangle can be defined as product of length and breadth.

We know that the area of the rectangle is given by the function A(x) = x² + 8x, where x is the width of the rectangle. We also know that the area of the rectangle is 33 in². So we can set up the equation:

x² + 8x = 33

To solve for x, we can rearrange the equation and set it equal to zero:

x² + 8x - 33 = 0

We can now use the quadratic formula to solve for x:

[tex]x = (-b\±\sqrt{(b^2 - 4ac)}) / 2a[/tex]

where a = 1, b = 8, and c = -33. Substituting these values, we get:

[tex]x = (-8\±\sqrt{(8^2 - 4(1)(-33))}) / 2(1)[/tex]

[tex]x = (-8\± \sqrt{(256)}) / 2[/tex]

x = (-8 ± 16) / 2

So x = -12/2 or x = 4.

Therefore, the width of the rectangle cannot be negative, we discard the negative solution and conclude that the width of the rectangle is 4 inches.

What is the discount?

A discount is a reduction in the price of a product or service that is offered by a seller to a buyer. It is a form of incentive that is used to encourage customers to purchase goods or services, often by making them more affordable or attractive.

To compare the two deals, we need to calculate the sale price per sheet for each deal.

In the previous example, the sale price per sheet was $15.00 after a 20% discount off the regular price of $18.00.

In this example, the sale price per sheet is 30% off the regular price of $18.00, so we can calculate the sale price per sheet as:

Sale price per sheet = Regular price per sheet - Discount amount

Sale price per sheet = $18.00 - (30% x $18.00)

Sale price per sheet = $18.00 - $5.40

Sale price per sheet = $12.60

Comparing the two deals, we can see that the sale price per sheet in this example is lower than the sale price per sheet in the previous example. Therefore, the better deal is the 30% discount off the regular price of $18.00, which results in a sale price per sheet of $12.60.

Therefore, the sale price per sheet in this example is $12.60.

The required number of tubs are 17.55 tubs.

To solve the problem, we need to find the total amount of ice cream used in ounces and then convert it to pounds to find the number of tubs used.

Number of scoops for regular cones = 2 scoops/cone

Number of scoops for large cones = 3 scoops/cone

Total number of scoops of ice cream used for regular cones = 2 scoops/cone x 234 cones = 468 scoops

Total number of scoops of ice cream used for large cones = 3 scoops/cone x 156 cones = 468 scoops

Total number of scoops of ice cream used = 468 scoops + 468 scoops = 936 scoops

Total amount of ice cream used in ounces = 936 scoops x 3 ounces/scoop = 2808 ounces

Total amount of ice cream used in pounds = 2808 ounces / 16 ounces/pound = 175.5 pounds

Number of tubs of ice cream used = 175.5 pounds / 10 pounds/tub = 17.55 tubs

Therefore, the angle between vector A and the positive e axis (which is the positive x-axis) is 60.255°.

To find the angle between vector A = (25 m)i + (45 m)j and the positive e axis, we first need to find the direction of vector A.

We can find the direction of vector A by taking the arctangent of the y-component over the x-component of the vector:

θ = tan⁻¹ (y/x)

where θ is the angle between the vector and the positive x-axis.

In this case, the y-component of vector A is 45 m and the x-component is 25 m:

Step-by-step explanation:

Answer:

(1 , -2)

Step-by-step explanation:

We are told that there is a translation of (x-4 , y-3)

This simply means that the x-axis moves to the left by 4 points and that the y-axis moves down 3 points. (if it was a plus not minus then points would move up and to the right)

1) Move the x-axis

We can see that the x-axis of b is 5. To move it to the left 4 we subtract 5 by 4

2) Move the y-axis

We can see that the y-axis of b is 1. To move it down we subtract 1 by 3

This leaves us with (1 , -2)
