Answer:

26-3.50-8x=16.18

Step-by-step explanation:

To create an equation representing what she spent, we need to start with the money she had and end with the money she has left.

We know that she originally had $26, but when she was done shopping, she had $16.18. To get from $26 to $16.18, you have to subtract the cost. That gives you 26 - [ cost ] = 16.18

We know that she spent $3.50 on a notebook and  8 pens of an unknown cost. The unknown cost can be represented by x. To find the total cost, you must add the costs of what she bought together. That gives you 3.50 - 8x.

Plug the expression of the cost into the equation, and boom it's done.

26 - 3.50 - 8x = 16.18

To find the equation representing the money Amy spent on school supplies, we can use the given information and set up an equation. By solving the equation, we can find the cost of one pen and calculate the total amount of money Amy spent.

To represent the money Amy spent, we need to find the cost of 8 pens. Let the cost of one pen be x. The notebook cost $3.50, so the total money spent on the notebook and pens can be represented as:

$3.50 + 8x

According to the problem, Amy had $16.18 left after buying the notebook and pens. So we can set up the equation:

$26 - ($3.50 + 8x) = $16.18

Simplifying the equation, we have:

$26 - $3.50 - 8x = $16.18

$22.50 - 8x = $16.18

Subtracting $22.50 from both sides, we obtain:

-8x = -$6.32

Multiplying both sides by -1, we get:

8x = $6.32

Dividing by 8 on both sides, we have:

x = $0.79

Therefore, the cost of one pen is $0.79.

Answer:

2/3 5/10 7/8 1/2

Step-by-step explanation:

hello  :

2/3 =(2×8)/(3 ×8) = 16/24

5/10 = 1/2= (1×12)/(2 ×12)=12/24

7/8= (7×3)/(8 ×3)= 21/24

the greater is : 7/8

To determine which of the fractions 2/3, 5/10, 7/8, and 1/2 is the greatest, we must first convert the fractions to decimals. Once converted, 7/8 (0.875) is the highest decimal value, thereby making it the greatest fraction.

To figure out which is greater among 2/3, 5/10, 7/8 and 1/2, we need to convert each of these fractions into decimals because it is easier to compare decimals than fractions.

So, 2/3 = 0.6667, 5/10 = 0.5, 7/8 = 0.875 and 1/2 = 0.5.

Comparing these decimals, it is clear that 7/8 (which equals to 0.875) is the greatest among the four.

Final answer:

To solve the equation 0.03x - 0.1 = 2.6, you add 0.1 to both sides and then divide by 0.03, resulting in the value of x being 90.

Explanation:

In the equation 0.03x - 0.1 = 2.6, to find the value of x, we first add 0.1 to both sides of the equation to isolate the term with x on one side. This gives us 0.03x = 2.7. Next, we divide both sides of the equation by 0.03 to solve for x, which gives us x = 2.7 / 0.03. Therefore, the value of x is 90.

Answer:

2926.32 cubic inches

Step-by-step explanation:

Given the information:

=> its radius is: 9.5/2 = 4.75 in

As we know, the formula used to find the volume of the sphere is:

V =π [tex]\frac{4}{3} r^{3}[/tex]

=> the volume of the basketball is:

V = π [tex]\frac{4}{3} 4.75^{3}[/tex]

= 448.69 cubic inches

As we know, the formula used to find the volume of a cube is:

V = [tex]a^{3}[/tex]

=> the volume of the box:

V = [tex]15^{3}[/tex] = 3375 cubic inches

Hence, The volume of foam there is needed to complete the box is the subtraction between the two volumes above:

= the volume of the box - the volume of the basketball

=  3375 - 448.69

The given statement is true.

In general, the growth rate of exponential functions is far greater than the quadratic function. This can be illustrated through an example.

Consider an exponential function  and a quadratic function .

Note that the leading coefficient of the quadratic function is far greater than the base of the exponential function but still the exponential function will exceeds the quadratic function after x = 15.664 as shown in the graph below.

Therefore, we can conclude that the given statement is correct.

The required value of x would be 8 to make LK Il OM for the shown triangle.

The angle bisector theorem is a geometric theorem that relates the lengths of the sides of a triangle to the lengths of the segments that bisect the opposite angles.

The line segment splits one side of a triangle into segments of length NO and NM, then the other two sides of the triangle are split into segments of length NK/KM and NL/LO respectively.

So, NK/KM = NL/LO

(x+2)/(x-3) = x/(x-4)

x² - 2x - 8 = x²- 3x

3x - 2x = 8

x = 8

Thus, the required value of x would be 8.

Answer:

B is the correct answer

Step-by-step explanation:

Let’s write the equation for Tim according to the question, that is t = 14h

Now for sheri, looking at the table, we can see that in two hours, he sells 14 tickets . This means that he sells at an average rate of 7 tickets per hour

Modeling his selling rate, with t being the number of tickets and h being the number of hours, we have;

t = 7h

Tim’s rate is t/h = 14

While sheri’s rate is t/h = 7

We can see that Tim’s rate is double Sheri’s rate

The rate of a linear function is simply the slope of the function.

The true statement is (b) the rate that Tim sells raffle tickets is double the rate that Sheri sells raffle tickets.

Tim's equation is given as:

[tex]t = 14h[/tex]

A proportional linear equation is represented as:

[tex]t = mh[/tex]

Where m represents the slope/rate.

This means that:

[tex]m = 14[/tex] --- Tim's rate

The slope of Sheri's table is calculated using:

[tex]m = \frac{y_2-y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]m = \frac{28 -14}{12 -10}[/tex]

[tex]m = \frac{14}{2}[/tex]

[tex]m = 7[/tex] ---- Sheri's rate

By comparison:

[tex]14 = 7 \times 2[/tex]

This means that: Tim's rate doubles Sheri's rate.

Answer: Dakota was less than 51 inches last summer.

Step-by-step explanation: First of all let us represent Dakota's height last summer by letter x.

The height requirement for the roller coaster is given as 54 inches. This means Dakota must be 54 inches or higher in order to be allowed on the ride. However, Dakota is too short to ride. This can be represented mathematically as x < 54.

If However, last summer Dakota grew 3 inches taller, then we can also represent this mathematically as x + 3 < 54.

To solve for this;

x + 3 < 54

Subtract 3 from both sides of the inequality

x < 51. (That is x is less than 51)

Since Dakota's height has been represented by x, we can now interpret this inequality as;

Dakota was less than 51 inches tall last summer.

Answer:

45 degrees

Step-by-step explanation:

If KL = MN, and LM =3 and KN = 13, then HN = 13 - (13-3)/2 = 8

LN =  sqrt(HN^2 + LH^2) -->

LN = sqrt89 sqrt(8^2 + LH^2) -->

89 = 64 + LH ^2 -->

25 = LH^2 -->

LH = 5

Because HN  = 8, HK = 13 - 8 = 5

That makes both legs equal, which makes m∠LKN = 45 degrees

The angle  m∠LKN is equal to 45 degrees.

To understand more, check below explanation.

It is given that,

KL = MN, LM =3 , KN = 13 and LN [tex]=\sqrt{89}[/tex]

So that, HN = 13 - (13-3)/2 = 13 - 5 = 8

    [tex]LN = \sqrt{(HN)^{2}+(LH)^{2} }\\\\\sqrt{89} = \sqrt{(8)^{2}+(LH)^{2} }\\\\89=64+(LH)^{2} \\\\LH=\sqrt{25}=5[/tex]

Since,  HN  = 8. So that,  HK = 13 - 8 = 5

In a triangle, if two sides are equal. Then, opposite angle of both sides are also equal.

In triangle LKH,   LH = HK = 5 and [tex]\angle H=90[/tex]

So that,     m∠LKN = 90/2 = 45 degree.

Hence, the angle  m∠LKN is equal to 45 degrees.

Jada's reasoning about the temperatures is incorrect because in negative numbers, the lower the value, the colder the temperature. Hence, Anchorage at -21°C was colder than Minneapolis at -14°C.

Jada's statement that "-14 is also less than -21" is incorrect when referring to temperatures in degrees Celsius. In fact, when we work with negative numbers, especially temperatures, the higher the negative number, the warmer the temperature. That is, -14°C is warmer than -21°C. Therefore, it was actually colder in Anchorage, Alaska at -21°C compared to Minneapolis, Minnesota at -14°C. To understand this better, we can look at a thermometer or a number line where numbers to the right are higher (warmer) than those to the left.

Answer:

medium 156+240+105=501

small 204 + 120=324  

large 40+240  =280

Step-by-step explanation:

600 of what ever the percentage or the fraction to find each small and large also medium.

example = 600 x 34% =204

another example is 400 x 3/10 = 40

The total number of medium packets of mints bought by the three shopkeepers Anne, Ben and Chas is calculated to be 622, using ratios and percentages to determine the breakdown of packets bought.

To solve this problem, we first find out the number of small, medium, and large packets each shopkeeper buys. For Anne, if 34% of 600 packets are small, she buys 0.34 * 600 = 204 small packets. Then, from the remaining packets 49% are large, which makes 0.49 * 600 = 294 large packets. The rest are medium packets, making 600 - 204 - 294 = 102 medium packets.

For Ben, 3/10 of his 400 packets are small, which makes 3/10 * 400 = 120 small packets. Also, 1/10 of his packets are large, hence 1/10 * 400 = 40 large packets. The rest, thus, are medium: 400 - 120 - 40 = 240 medium packets.

For Chas, if the ratio of small packets to medium packets is 3:4, meaning for every 3 small packets, there are 4 medium packets. She bought 210 small packets, thus for medium packets, using the ratio, it becomes 210 * (4/3) = 280 medium packets.

The total number of medium packets that these shopkeepers buy is thus: 102 + 240 + 280 = 622 medium packets.

The only options equivalent to 2:9 are B and C.

Step-by-step explanation:

A ratio is a comparison between two or more numbers.

When two ratios are equivalent, they describe the same relationship between numbers.

An equivalent ratio is to a number is usually the same ratio in which the numerator and denominator (first and second number) have been multiplied by a common multiple.

To find if two ratios are equivalent, we have to put them in their simplest forms and compare.

The ratio we are comparing other ratios with is 2:9

So, we will put all other ratios in their simplest form and see if it gives us 2:9

A. 9:2 - This is already in its simplest form and it is not equal to 2:9.

B. 18:81 - To put this in simplest form, we divide both numbers by 9:

18:81 = 2:9

Hence, this is an equivalent ratio to 2:9.

C. 12:54 - To put this in simplest form, we divide both numbers by 6:

12:54 = 2:9

Hence, this is an equivalent ratio to 2:9.

D. 18:4 - To put this in simplest form, we divide both numbers by 2:

18:4 = 9:2

This is not the same as 2:9.

E. 20:45 - To put this in simplest form, we divide both numbers by 5:

20:45 = 4:9

This is not the same as 2:9.

The only options equivalent to 2:9 are B and C.
