(C) 7/10 cup is the correct answer

Step-by-step explanation:

First of all we will calculate the 40% of grandmother's recipe then add it to the given flour in grandma's recipe

So,

The amount of flour in grandma's recipe = F_g = 1/2 cups

Calculating percentage

[tex]=40\%\ of\ \frac{1}{2}\\=\frac{40}{100}*\frac{1}{2}\\=\frac{2}{10}[/tex]

So Evelyn needs to add 2/10 cups more to the original quantity.

So,

Flour used by Evelyn:

[tex]=\frac{1}{2}+\frac{2}{10}\\\\=\frac{5+2}{10}\\\\=\frac{7}{10}\ cups[/tex]

Hence,

(C) 7/10 cup is the correct answer

Final answer:

To find the radius of the circular trampoline, we can use the formula for the area of a circle and rearrange it to solve for the radius. The radius of the trampoline is approximately 6.5 ft (rounded to the nearest tenth).

Explanation:

To find the radius of the circular trampoline, we can use the formula for the area of a circle, which is A = πr². In this case, the area is given as 132.2 ft². We can rearrange the formula to solve for the radius:

r² = A/π

r² = 132.2/π

r ≈ √(132.2/π)

r ≈ √(42)

r ≈ 6.5 ft (rounded to the nearest tenth)

Final answer:

To find the radius of the trampoline, we use the formula for the area of a circle and rearrange it to solve for the radius. After substituting the given area and approximating π as 3.14, we find that the radius is approximately 6.5 ft when rounded to the nearest tenth.

Explanation:

The area of a circle is given by the formula A = πr², where A is the area and r is the radius of the circle. Given the area of the trampoline as 132.2 ft², we can solve for the radius using the area formula. We rearrange the formula to solve for the radius: r = √(A/π).

Substituting the given area and the approximate value for π (3.14), we get r = √(132.2/3.14). This simplifies to r = √(42.085...), which is approximately r = 6.487 ft. Rounding to the nearest tenth gives us a radius of 6.5 ft.

x=-10/23

Step-by-step explanation:

-23x=10

x=10/-23

x=-10/23

Answer:

x = -15 thus c: is your answer

Step-by-step explanation:

Solve for x:

10 = (-2 x)/3

10 = (-2 x)/3 is equivalent to (-2 x)/3 = 10:

(-2 x)/3 = 10

Multiply both sides of (-2 x)/3 = 10 by -3/2:

(-3 (-2) x)/(2×3) = (-3)/2×10

(-3)/2×(-2)/3 = (-3 (-2))/(2×3):

(-3 (-2))/(2×3) x = (-3)/2×10

(-3)/2×10 = (-3×10)/2:

(-3 (-2) x)/(2×3) = (-3×10)/2

(-3)/3 = (3 (-1))/3 = -1:

(-2-1 x)/2 = (-3×10)/2

(-2)/2 = (2 (-1))/2 = -1:

--1 x = (-3×10)/2

(-1)^2 = 1:

x = (-3×10)/2

10/2 = (2×5)/2 = 5:

x = -35

-3×5 = -15:

Answer:

0.3 > 0.09

Step-by-step explanation:

The comparison 0.3 > 0.09 is true.

0.3 = 0.300

0.300 > 0.009

All other options are false. They should have a less than sign instead of a greater than sign.

Final answer:

Upon comparison of decimal values in the given options, Option A (0.3 > 0.09) is the true comparison as 0.3 is greater than 0.09 when comparing the tenths place.

Explanation:

When comparing decimal numbers, you should look at the largest place value first and work your way to smaller place values to determine which number is larger. Let's evaluate each option:

A. 0.3 > 0.09: Comparing the tenths place, 3 is greater than 0. Therefore, this statement is true.

B. 0.04 > 0.2: Comparing the tenths place, 0 is less than 2. Therefore, this statement is false.

C. 0.29 > 0.38: Comparing the tenths place, both numbers are equal, but in the hundredths place, 9 is less than 8. Therefore, this statement is false.

D. 0.24 > 0.67: Comparing the tenths place, 2 is less than 6. Therefore, this statement is false.

E. 0.55 > 0.600: Comparing the tenths place, both numbers are equal, and in the hundredths place, 5 is equal to 0 followed by an additional 0, thus both numbers are equal and this statement is false.

Based on the above analysis, the correct answer is Option A. 0.3 > 0.09.

Answer:

(b) The number of pounds of berries each person would receive is [tex]1\frac{5}{8}[/tex]pounds.

Step-by-step explanation:

The amount of berries in first basket = 3 3/8 pounds

Now, [tex]3\frac{3}{8}  = 3+\frac{3}{8} = 3 + 0.375 = 3.375[/tex]

So, the amount of berries in first basket = 3.375 pounds

The amount of berries in second basket = 2 7/8 pounds

Now, [tex]2\frac{7}{8}  = 2+\frac{7}{8} = 2 + 0.875 = 2.875[/tex]

So, the amount of berries in second basket = 2.875 pounds

Now, the total berries = Berries in ( First + Second)  basket

                                      = 3.375 pounds +  2.875 pounds  

                                    = 6.25 pounds

So, the number of pounds each person would have = [tex]\frac{\textrm{Total weight of viable berries}}{\textrm{4}}  = \frac{6.25}{4} = 1.5625[/tex]

Now, [tex]1.5625 = 1 + 0.5625  = 1 + \frac{5625}{10000}  = 1 + \frac{5}{8}  = 1\frac{5}{8}[/tex]

So, the number of pounds of berries each person would receive is [tex]1\frac{5}{8}[/tex]pounds.

The volume of the silo is 461.81 m³

Step-by-step explanation:

A barn silo, excluding the top, is a cylinder

We need to find the volume of the silo

∵ The silo is shaped a cylinder

∵ The volume of a cylinder = base area × height

∵ The base is shaped a circle

∵ Area a circle = π r², where r is the radius of the circle

∴ The volume of the silo = π r² × h

∵ The diameter of the silo = 7 m

∵ The radius of a circle is half the diameter

∴ The radius of the silo = [tex]\frac{1}{2}[/tex] × 7 = 3.5 m

∵ The height of the silo = 12 m

- Substitute the values of r and h in the rule of volume

∴ The volume of the silo = π (3.5)² × 12

∴ The volume of the silo = 147 π = 461.81 m³

The volume of the silo is 461.81 m³

Final answer:

The volume of a barn silo that is shaped like a cylinder with a diameter of 7 meters and a height of 12 meters is approximately 461.7 cubic meters.

Explanation:

To calculate the volume of the silo which is in the shape of a cylinder, we use the formula V = πr²h, where V is the volume, r is the radius, and h is the height. The diameter of the silo is given as 7 meters, so the radius is half of that, which is 3.5 meters. The height of the silo is 12 meters. Plugging these values into the formula gives:

V = π × (3.5 m)² × 12 m

V = π × 12.25 m² × 12 m

V = π × 147 m³

Assuming π to be approximately 3.14159, the calculation results in:

V = 3.14159 × 147 m³ = 461.7 m³ (approx)

So, the volume of the silo is approximately 461.7 cubic meters.

Answer:

There were 120 events planned.

Step-by-step explanation:

We are given the following information in the question:

f(x) represents the total monthly expenses for planning x events.

[tex]f(x) = 50(2x+1) + 300[/tex]

Cost of expenses for the company at the end of one month = $12,350

We have to find the number of events planned that is we have to find the value of x.

[tex]f(x) = 50(2x+1) + 300 = 12350\\50(2x+1) + 300 = 12350\\100x + 50 + 300 = 12350\\100x + 350 = 12350\\100x = 12350-350\\100x = 12000\\\\x = \displaystyle\frac{12000}{100} =120[/tex]

Thus, there were 120 events planned.

Final answer:

The correct statement must be that the slope of the equation is the cost per round of $33.47, and the y-intercept is the initial membership fee of $17.72, since the slope represents the additional cost per round and the y-intercept the initial cost at zero rounds.

Explanation:

In the function T = 33.47r + 17.72, which represents the total cost T of playing miniature golf as a function of the number of rounds played r, the coefficient of r represents the slope and the constant term is the y-intercept. The slope indicates the additional cost for each additional round of golf played, while the y-intercept represents the initial cost when no rounds are played, which can be interpreted as the membership fee. Therefore, the correct statement about the cost structure of the Cape Gerbil City Miniature Golf Club is A: The slope is the cost per round $33.47, and the y-intercept is the membership fee of $17.72.

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have two points that belong to the AB line:

[tex](x_ {1}, y_ {1}) :( 2,1)\\(x_ {2}, y_ {2}): (- 1, -8)[/tex]

We can find the slope:

[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-8-1} {- 1-2} = \frac {-9} {- 3} = 3[/tex]

Answer: perpendicular

Step-by-step explanation:

Final answer:

The slopes of the two lines given by the equations 3x-6y=2 and 18x+9y=8 are 1/2 and -2 respectively. Since these slopes are neither equal nor negative reciprocals, the lines are neither parallel nor perpendicular.

Explanation:

To decide whether the pair of lines is parallel, perpendicular, or neither, we need to find the slopes of the lines. The lines are given by the equations 3x-6y=2 and 18x+9y=8. To find the slope of each line, we must rewrite the equations in slope-intercept form (y=mx+b), where m represents the slope

For the first line, 3x-6y=2, we isolate y:

So the slope of the first line is 1/2.

For the second line, 18x+9y=8, we isolate y:

The slope of the second line is -2.

Since the slopes of the two lines are not equal and not negative reciprocals of each other, the lines are neither parallel nor perpendicular.

Answer:

  (x, y) = (43/53, 18/53)

Step-by-step explanation:

If we want to eliminate the x-terms, we multiply the first equation by 7 (opposite of the x-coefficient in the second equation), and we multiply the second equation by 5 (x-coefficient in the first equation). Then we add the result.

  7(5x -9y) +5(-7x +2y) = 7(1) +5(-5)

  35x -63y -35x +10y = 7 -25

  -53y = -18 . . . . simplify. Note the x-terms are gone.

  y = 18/53 . . . . . divide by -53

__

Putting this value of y in the first equation, we get ...

  5x -9(18/53) = 1

  5x = 1 + 162/53 = 215/53 . . . . . add 9y to both sides, simplify

  x = 43/53 . . . . . . . . . . divide by 5

The solution is (x, y) = (43/53, 18/53).

Imagine a rectangle with one corner on the origin and the opposite on the point. Rotate the rectangle about the origin and see where the point lands.

To find the new coordinates of point B after a 90° clockwise rotation around the origin, you apply the rotation rule: (x, y) becomes (y, -x). The original coordinates are needed to calculate the exact new position of point B.

The student is asking about the result of a 90° clockwise rotation of a point around the origin in the Cartesian coordinate system. To find the new coordinates of point B after the rotation, we use the rule for 90° clockwise rotation, which is (x, y) becomes (y, -x). If the original coordinates of point B are (x₂, y₂), the new coordinates after the rotation will be (y₂, -x₂).

Without knowing the original coordinates of point B, we cannot give the exact new coordinates. However, if the student provides the initial coordinates, the new coordinates can be calculated using the rotation rule mentioned.
