At Gumdrops Galore candy store, Gina and her sister each fill a bag with gumdrops. Gina's bag of black gumdrops weighs 1 4 of a pound. Gina pays for both her gumdrops and her sister's red gumdrops. In all, Gina buys 3 8 of a pound of gumdrops. She wants to know how much her sister's red gumdrops weigh. Use an equation to find the weight of her sister's red gumdrops.

Answers

Answer:

1/8 of a pound

Step-by-step explanation:

Gina's bag of gumdrops : 1/4 of a pound

Gina's + sister's bag of gumdrops : 3/8 of a pound

To find how much her sister's gumdrops weighed, you will have to subtract fractions.

Equation : 3/8 - 1/4 or 3/8 - 2/8

To subtract, you need to make sure the denominators are the same.

1 × 2

-------  =  2/8

4 × 2

Now, you can subtract. Subtract the numerators.

3/8 - 2/8 = 1/8

So, Gina's sister's red gumdrops weigh 1/8 of a pound.

Hope this helped !

Gina's sister's red gumdrops weigh 1/8 of a pound.

How to determine the weight of Gina's sister's red gumdrops

Let's use an equation to find the weight of Gina's sister's red gumdrops.

Let x be the weight of Gina's sister's red gumdrops in pounds.

According to the information given:

Gina's bag of black gumdrops weighs 1/4 pound.

Gina pays for both her gumdrops and her sister's red gumdrops, totaling 3/8 pound of gumdrops.

Weight of Gina's gumdrops (black gumdrops) + Weight of sister's gumdrops (red gumdrops) = Total weight of gumdrops purchased

1/4 + x = 3/8

Solve for x

x = 3/8 - 1/4

To subtract fractions, we need a common denominator, which is 8:

x = (3/8) - (2/8)

x = 1/8

Therefore, Gina's sister's red gumdrops weigh 1/8 of a pound.

Find which number I am. ​

Answers

Answer:

3286714

Step-by-step explanation:

Let the digits of the number be :

ABCDEFG

Our given conditions :

G = 4F [ones digit is four times the tens digit]G + F = B + A [sum of the ones and tens digits is equal to the sum of the lakhs and ten lakhs digits]C + D = 2E [sum of the ten thousands and thousands digits is equal to the double of the hundreds digit]A > B and C > D [ten lakhs digit is greater than the lakhs digit , and the ten thousands digit is greater than the thousands digit]

Solving :

Condition 1 : G is either 1 or 2 and F is either 4 or 8For now, let G be 1 and F be 4 Now G + F = A + BThen A + B = 5 [but not 1 + 4] ⇒ A can be 3 and B can be 2Now C + D = 2E and our remaining numbers are 5,6,7,8,9C and D can be 8 and 6, then their mean would be 7, which is E

Answers

Answer:

  v = 13

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, so AB ≅ AD. This relation gives rise to an equation we can solve for v.

  2v -3 = 6v -55

  52 = 4v . . . . . . . . . add 55-2v to both sides

The equation of the line that passes through (1,2) and is parallel to the line y=-5x+4, is y=-5x+7.

What is the equation of line?

The equation of the line is the way of representation of a line in the equation form.

The equation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.

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

Here, (m) is the slope of the line and (c) is the y intercept.

This line is parallel to the line which has to be find out is,

[tex]y=-5x+4[/tex]

As the parallel lines have same slope. Thus, the line which is required to find has a slope of -5.

Compare with standard equation of line, we get the slope of the line,

[tex]m=-5[/tex]

Thus, the equation of line become,

[tex]y=-5x+c[/tex]

The line passes through (1,2). Put these values in the above equation as,

[tex]2=-5(1)+c\\2=-5+c\\c=2+5\\c=7[/tex]

Thus, the equation become,

[tex]y=-5x+7[/tex]

Hence, the equation of the line that passes through (1,2) and is parallel to the line y=-5x+4, is y=-5x+7.

The circumference of the circle is 24 cm and the radius is √x+2. Find x and its radius. Use = 3.14 . Round your answer to two decimals.

Answers

[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]

Let's solve ~

Circumference of a circle :

[tex]\qquad \tt \dashrightarrow \:2 \pi r[/tex]

And we have been given that Circumference = 24 cm

So, let's equate them and find radius (r) :

[tex]\qquad \tt \dashrightarrow \:2 \pi r = 24[/tex]

[tex]\qquad \tt \dashrightarrow \:r = \dfrac{ 24}{2 \pi}[/tex]

[tex]\qquad \tt \dashrightarrow \:r = \dfrac{ 12}{3.14}[/tex]

[tex]\qquad \tt \dashrightarrow \:r = 3.82 \: \: cm[/tex]

So, we got the radius here. now let's equate it with expression in terms of x to find value of x

[tex]\qquad \tt \dashrightarrow \: \sqrt{x + 2} = 3.82[/tex]

[tex]\qquad \tt \dashrightarrow \:{x + 2} = (3.82) {}^{2} [/tex]

[tex]\qquad \tt \dashrightarrow \:{x } \approx 14.59 - 2[/tex]

[tex]\qquad \tt \dashrightarrow \:{x } \approx 12.59 \: \: cm[/tex]

x = 12.61

===========

[tex]\bold{C = 2\pi r}[/tex]                                     [ C = 24, π = 3.14, r = √x+2 ]

2(3.14)(√x+2) = 24

(6.28)(√x+2) = 24

√x+2 = 24/6.28

x+2 = (24/6.28)²

x = (24/6.28)² - 2

x = 12.60505497

x ≈ 12.61                ( rounded to nearest two decimal places )

Find the perimeter and the area of the regular polygon with the given apothem a and side length s.

Answers

Step-by-step explanation:

apothem : distance from the center of the object to the side(s).

area : 1/2 × perimeter × apothem

perimeter : 9 x side

perimeter = 9×15 in = 135 in

area = 1/2 × 135 × 20.6 = 1,390.5 in²

The perimeter and area of a nonagon with apothem of 20.6 inches and side of 15 inches are 135 inches and 1390.5 inches² respectively.

What is a nonagon?

A nonagon is a polygon with 9 sides. The perimeter and area can be found as follows;

Perimeter = length of the whole sides

side length = 15 inches

P = 9 × 15

p = 135 inches

Area of a nonagon = 1 / 2 pa

where

a = apothemp = perimeter

Therefore,

apothem = a = 20.6 inches

area of the nonagon = 1 / 2 × 135 ×  20.6

area of the nonagon = 2781 / 2
