What is the sum of -3 2/8 + 1/4

Answer:

50.27 square inches

Step-by-step explanation:

If you look at the logo for the Super Snacks Company, you'll see it's basically a cylinder that has been cut and twisted, but if you just curve the top part the other way around, you'll have a perfect cylinder again.

We can then calculate the lateral surface area of the cylinder, to do so we use the following formula:

L = 2 * π * r * h

Which means we multiply by 2 by the constant π (3.1416) by the radius of the cylinder (in our case 2 inches, since the full diameter is 4 inches) and the height (in our case 4 inches).  So, we enter the numbers in the formula and solve it:

L = 2 * 3.1416 * 2 * 4 = 50.2656 square inches.

There is no solution

There are no values of x that will make the equation true.

x approx 0.493942

Step-by-step explanation:

first set the first equation equal to x

subtract 2y from both sides

x=27-2y now plug this in to the other equation

2(27-2y)+3y=46 distribute

54-4y+3y=46 --> 54-y=46 now subtract 54 from both sides -y=-8 --> D)y=8

If you weren't asked to show work you could just plug the choices given into the equation

Final answer:

By using the elimination method and subtracting the second given equation from the doubled first equation, we find that the solution for y in the system of equations is y=8.

Explanation:

We are tasked with finding the solution for y in the system of equations:

x + 2y = 27

2x + 3y = 46

To solve the system, we can use either the substitution method or the elimination method. Let's use the elimination method for this problem:

Multiply the first equation by 2:

(2)(x + 2y) = (2)(27)

2x + 4y = 54

Now we have:

2x + 4y = 54 (from step 1)

2x + 3y = 46 (original second equation)

Subtract the second equation from the first:

(2x + 4y) - (2x + 3y) = 54 - 46

y = 8Thus, y=8 is the solution to the system of equations, which corresponds to option D.

Answer:

1. 42 + t/6

2. 42 + 12/6

3. 42 + 2

4. 44

Step-by-step explanation:

-You start of with 42 + t/6. If t = 6

-If t = 6, the next step should be to replace t with 12 So it would be 42 + 12/6.

-If we have 12/6 we know to divide. 12 divided by 6 is 2. So we would replace 12/6 with 2. Now we have 42 plus 2

-42 plus 2 is 44.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a school is sending six teachers and some students to attend a technology fair the admission price for teachers is 8.50 each and the admission price for students is $6 each if the budget set aside by the school for this event is $250.

The number of the students will be calculated as,

( 6 x 8.5 ) + N x 6 = 250

6N = 250 - 51

N = 199 / 6

N = 33

Hence, the number oof the students will be 33.

Answer:

13.6

Step-by-step explanation:

Add all of the ages up:

14 + 14 + 13 + 13 + 13 + 15 + 14 + 14 + 13 + 13 = 136

Then divide that by 10:

136/10 = 13.6

To calculate the mean absolute deviation of the ages in Mrs. Kiperling's class, first calculate the mean, then the absolute differences between each age and the mean, and finally average those differences to get an MAD of 0.6 years.

The mean absolute deviation (MAD) of a set of numbers is a measure of how spread out the numbers are from the average (mean). To calculate the MAD, we first find the mean of the data set, then find the absolute differences between each data point and the mean. Finally, we average those absolute differences to get the MAD. In this case, we begin by calculating the mean of the student ages:

Mean age = (14 + 14 + 13 + 13 + 13 + 15 + 14 + 14 + 13 + 13) / 10 = 13.6

Next, we find the absolute differences from the mean for each age:

Now we calculate the mean of these absolute differences:

MAD = (0.4 + 0.4 + 0.6 + 0.6 + 0.6 + 1.4 + 0.4 + 0.4 + 0.6 + 0.6) / 10 = 6 / 10 = 0.6

So, the mean absolute deviation of the student ages in Mrs. Kiperling's class is 0.6 years.

Step-by-step explanation:

Look at the picture.

We connect two congruent trapezoids as in the picture.

We created a parallelogram with a base length of b₁ + b₂ and a height h equal to the height of the trapezoid.

The formula of an area of a parallelogram:

[tex]A_p=(base)(height)\to A_p=(b_1+b_2)h[/tex]

The area of the trapezoid is half of the parallelogram area.

Therefore we have the formula of an area of trapezoid:

[tex]A_t=\dfrac{(b_1+b_2)h}{2}[/tex]

Therefore we need to be added the bases of a trapezoid.

Answer:

y = 6√3 and x = 6

Step-by-step explanation:

this is a 30-60-90 triangle.  The side opposite the 30° angle corresponds to the side of length 1  in the most basic 30-60-90 triangle; the side opp. 60° to the side of length √3; and the hyp. to the side of length 2.

To find y, write and solve an equation of ratios, as follows:

adj side           adj side      (adjacent to the 30° angle)

    y                       √3

 hypo               hypo    then (cross multiplying):  2y = 12√3, and

    12                     2       y = 6√3

If the hypo here is 12 and the adj side (y) is 6√3, then we can use the Pyth. Theorem to find the third side (x):

[12]² = [6√3]² - x²  ↔ 144 = 36(3) - x²   ↔  36 = x².  So x = 6 here.

Answer:

x = 6

y ≈ 10. 40

Step-by-step explanation:

Using the SOHCAHTOA principle we can solve for x and y since the angle is known and it is a right angle triangle.

hypotenuse = 12

adjacent = x

opposite = y

cos 60° = adjacent/hypotenus

cos 60° = x/12

cross multiply

x = 12 cos 60°

x = 12 × 0.5

x = 6

Finding y

sin 60° = opposite/hypotenuse

sin 60° = y/12

cross multiply

y = 12 sin 60°

y  = 12 × 0.8660254038

y =  10.392304845

y ≈ 10. 40

Answer:

$90

Step-by-step explanation:

Look at the number 7 on the bottom right of the graph. That means at the end of 7 weeks. Now look vertically up from there until you see a point directly above 7 weeks. Look to the left of that point, and you see that the point directly above 7 weeks is at the level of $90. That means that at the end of 7 weeks, he had $90.

3x^2 +6y^2 = 18

Divide each term by 18 to make the right side equal 1:

3x^2/18 + 6y^2/18 = 1

Simplify each term:

x^2/6 + y^2/3 = 1

Answer:

1/169

Step-by-step explanation:

There are total 52 cards in deck. Also, there are 4 kings and 4 jacks in the deck.

Probability of choosing a king out of 4 kings and total there are 52 cards

∴ Ans1 = ⁴C₁/⁵²C₁ = 4/52 = 1/13

The cards are drawn with replacement so again there will be total 52 cards.

Probability of choosing a jack out of 4 jacks and total there are 52 cards

∴Ans2 = ⁴C₁/⁵²C₁ = 4/52 = 1/13

So, ans=Ans1 * Ans2 = 1/13 *1/13 = 1/169

Answer:

d

Step-by-step explanation:

To eliminate the fractions in the equation multiply all term on both sides by the lowest common multiple of 2 and 3, that is 6

3x + 18 = 4x + 6 ← equation with no fractions

Subtract 4x from both sides

- x + 18 = 6 ( subtract 18 from both sides )

- x = - 12 ( multiply both sides by - 1 )

x = 12 → d

Answer:

x = 6

Step-by-step explanation:

The radius in this case measures; 20/2 = 10 since the diameter is 20.

The chord measuring 16 units has been bisected, hence each portion measures 8 units.

We now apply Pythagoras theorem since we are dealing with a right angled triangle with 2 given sides;

x^2 = 10^2 - 8^2

x^2 = 36

x = 6

Final answer:

Without a specific equation or sufficient context, it is not possible to determine the correct value of x from the provided answer options (4, 6, 5, 7). The provided excerpts mention various unrelated values and scenarios involving x.

Explanation:

The specific value of x is not provided in the context of the information given, making it impossible to accurately determine its value. The excerpts given mention several different equations and scenarios, including various values for x such as x=3, x=-7, and instances where x=1 is a solution. However, these are not directly related to a given problem or an equation we can solve in this context.

Moreover, references to checking answers online with exercise codes and the mention of convergence related to initial guesses suggests that these excerpts are from a discussion involving solving equations using numerical methods, possibly from a textbook or set of course notes. To find the correct value of x, we would need to know the specific equation or problem we are trying to solve.

Without a clear and specific equation to solve, or additional context, we cannot accurately determine which of the answer options (4, 6, 5, 7) is the correct value of x.

Answer:

814

Step-by-step explanation:

there has to be a number between 4,8

so either 4 can be at hundred position or 8 can be at hundredth position.

but since 1 comes before 4, then 1 has to be at tens place and 4 has to be at one's place.

so number is 814

Using the given clues, we can determine that the three-digit mystery number with digits 1, 8, and 4, where 1 comes before 4 and 4 is not next to 8, is 184.

The mystery number is a three-digit number where the digits are 1, 8, and 4. With the given clues that the digits 4 and 8 are not next to each other and that 1 comes before 4, we must arrange the digits accordingly.

Since we are told the exact sequence for 1 and 4, with 1 coming before 4, and knowing that 8 cannot be next to 4, the possible arrangement is: the digit 1 first, then 8, and finally 4.

Following these conditions, the mystery number is 184.
