Albert wants to buys some pens. He is comparing 4 different packs of pens. The number of pens in each pack and the cost of the pack is shown in the table below. Which two packs of pens have the same cost per pen? ​

Answer:

1            0.25

2            0.50

3            0.75

5            1.25

7            1.75

9            2.25

11            2.75

12           3.00

t=0.25s

The slant height of the cone is 39.7 cm

Explanation:

Given:

Lateral surface area of a cone = 558π cm²

Radius, r = 31 cm

Slant height, l = ?

We know:

[tex]A = \pi r\sqrt{h^2+r^2}[/tex]

Where,

h is the height of the cone

r is the radius

Solving the equation further:

[tex]558\pi = \pi r\sqrt{h^2+r^2} \\\\558 = 31\sqrt{h^2+(31)^2} \\\\(18)^2 = h^2 + 961\\\\324 = h^2+ 961\\\\h = 25.23[/tex]

Lateral height, H = ?

Applying pythagoras theorm,

(H)² = (h)² + (r)²

(H)² = (25.23)² + (31)²

(H)² = 636.55 + 961

(H)² = 1597.55

H = 39.7 cm

Therefore, the slant height of the cone is 39.7 cm

Given:

It is given that LON is a straight line. The measure of ∠LOM = (4x + 30)° and the measure of ∠MON = (8x + 90)°

We need to determine the value of m∠MON

Value of x:

Since, LON is a straight line and the angles LOM and MON are linear pairs of angles.

Since, linear pair of angles add up to 180°

Thus, we have;

[tex]\angle LOM+\angle MON=180^{\circ}[/tex]

Substituting the values, we get;

[tex]4x+30+8x+90=180[/tex]

            [tex]12x+120=180[/tex]

                      [tex]12x=60[/tex]

                         [tex]x=5[/tex]

Thus, the value of x is 5.

Value of m∠MON:

The measure of ∠MON can be determined by substituting x = 5 in the expression (8x + 90)°, we have;

[tex]m\angle MON=(8(5)+90)^{\circ}[/tex]

[tex]m\angle MON=(40+90)^{\circ}[/tex]

[tex]m\angle MON=130^{\circ}[/tex]

Thus, the measure of ∠MON is 130°

Answer:

It would be a point which is at (-4,-7).

The image of the point (4,-7) after a reflection over the y-axis is (-4,-7). This happens because the y-axis is the axis of symmetry during a reflection over this axis, changing the x-coordinate's sign while keeping the y-coordinate constant.

The image of a point after a reflection over the y-axis results in the x-coordinate of the point changing its sign. Therefore, the image of the point (4,-7) after a reflection in the y-axis would be (-4,-7). In other words, you move the point 4 units to the left across the y-axis while the y-coordinate remains unchanged.

This process is derived from the concept that the y-axis is the axis of symmetry in a reflection over the y-axis. As such, points on one side of the axis are mirrored on the other side, changing only the sign of the x-coordinate and keeping the y-coordinate constant.

A helpful way to visualize this is by drawing a coordinate grid and plotting the point (4,-7). By reflecting this point over the y-axis, you will see it lands at the point (-4,-7).

Answer:

900

Step-by-step explanation:

To get your answer, you can just multiply 20 seconds by 3 to get 60 seconds, which is a minute.

Since whatever you do on one side you have to do to the other, multiply 300 mi by 3 as well. That would get you 900.

The answer is that each book costs 26 dollars

Step-by-step explanation:

First we subtract 199 dollar from 7 =182

Then we divide 182 dollars to the seven book in order to find a unit =182/7=26

To prove this answer multiply 26 dollars than 7 books and see if the outcome is 182.Then subtract 199 from 182 and see if you got 17.

The number of apples Tyler purchased is the dependent variable.

The alphabetic character that expresses a numerical value or a number is known as a variable in mathematics.

A representation of an unknown numerical value in an equation or algebraic statement by a symbol, typically a letter. A variable can be defined as a quantity that is changeable and not fixed.

Given:

Tyler’s grocery receipt shows a charge of $0.25 for every apple he purchased.

'g' represent the amount on the grocery receipt.

'a' represent the number of apples purchased.

Therefore, 'a' is the variable here.

So, the amount of apple is independent variable but the purchased values if dependent variable.

Thus, the number of apple Tyler purchased is the dependent variable.

Final answer:

The independent variable is the number of apples purchased, as it determines the dependent variable, which is the total amount spent on apples in the grocery bill.

Explanation:

The independent variable in this scenario is the number of apples purchased (represented by a). This is because the independent variable is the one that is changed or controlled in a scientific experiment to test the effects on the dependent variable. In this case, Tyler decides how many apples to buy, and that decision directly affects the total cost, which is the dependent variable (g). The price of an apple, the weight of the apples, and the amount on the grocery bill are all dependent on the number of apples Tyler chooses to purchase. To find the total amount spent on apples, one would multiply the number of apples purchased by the cost per apple.

Answer: 4.01 x 107

Step-by-step explanation:

Answer:

4.01x10^7=40100000

Answer:

80 and 85

Step-by-step explanation:

Let a and b be those numbers

a*b = 6800

a - b = 5

Use the substitution method.

a = 5 + b

(5 + b)*b = 6800

5b + b*b = 6800

bb + 5b - 6800 = 0

b = -5/2  +   root(25 - 4*1*(-6800)) /2

b = -5/2 +  165/2

b = 80

or   b = - 85

a - b = 5

a - 80 = 5

a = 85

To find Sandy's allowance, we use the given information to set up an equation. After solving it, we determine that Sandy's weekly allowance is $10.

To determine Sandy's weekly allowance, we need to work backward from the information given. We know that she ended with $13 after spending half of her allowance on movies and earning an additional $8 from washing the car. Let's let the variable A represent Sandy's allowance. According to the problem, Sandy spent A/2 on movies, and when she added the $8 she earned, she had $13.

We can set up the equation as follows:

Now, we solve for A to find the allowance:

So, Sandy's weekly allowance is $10.

Step-by-step explanation:

Since they left a tip of 20% you find 20% of 25.60, and then add it to 25.60.

You add 5.12 and 25.60 because it was a tip, they gave that much more.  

So 20% which is 5.12.  

25.60 + 5.12 = 30.72

The measure of ∠B is 119°.

An exterior angle is a measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.

All the exterior angles are of the same measure, and therefore, their measure is (360/n)°.

The angle adjacent to 112° will form a straight angle along with 112° adding to 180° which makes ∠C=68°

Then;

a+c+51°= 180°

a+68°+51° = 180°

a+119° = 180°

a = 180° - 119°

a = 61°

Now,

a+b = 180°

61+b = 180

b = 180-61

b = 119°
