Answer: 6 gifts.

Step-by-step explanation:

I found the question elsewhere and it states that Eve needs 2/3 m for each gift.

Since Eve has 4 m, the number of gifts she can wrap is the 4 m she has divided by the 2/3 m required for each gift.

= 4 ÷ 2/3

= 4 × 3/2

= 12/2

= 6 gifts.

Note: When dividing by a fraction, you can multiply by it's inverse.

Answer:

independent is r and dependent is y

Step-by-step explanation:

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure.

a tree grows a ring for each year, therefore, to determine a trees age, you need to count the rings. the rings "r" dictate the age or years "y"

Answer:

El CD costaba $100 inicialmente.

Step-by-step explanation:

Dado que la información indica que el porcentaje de descuento es 20% y ese descuento tiene un valor de $20, puedes usar una regla de tres para encontrar el valor que representa el 100% que sería el valor inicial del CD dado que el 20% del valor es igual a $20:

20%  →  20

100% →    x

x=(100*20)/20=100

De acuerdo a esto, la respuesta es que el CD costaba $100 inicialmente.

Answer:

30 Lower level tickets

17 upper level tickets

Step-by-step explanation:

Let:

Lower level tickets = l

Upper level tickets = u

5l + 9u = 303 - - - (1)

8l + 10u = 410 - - - - - (2)

Multiply (1) by 8 and (2) by 5

40l + 72u = 2424 - - - (3)

40l + 50u = 2050 - - - (4)

Subtract (3) from (4)

22u = 374

u = 374 / 22

u = 17

Put u = 17 in (1)

40l + 72(17) = 2424

40l + 1224 = 2424

40l = 2424 - 1224

40l = 1200

l = 1200 / 40

l = 30

30 Lower level tickets

17 upper level tickets

Answer:

Multiply ; 40

Step-by-step explanation:

Given that :

Height, H of rectangular chest = H(x) = x+6.

Area of rectangular chest, A(x) = 20√x /3

Recall; Volume of chest = Base area * Height

(X + 6) * 20√x /3

(20x√x /3 ) + (20 * 6√x/3)

(20x√x /3 ) + (20 * 2 * 3√x/3)

(20x√x/3) + 40√x

The correct answer for the drop-down menu is that the first blank is multiply and the second blank is 40.

Based on the fact that we have been given the Height =H of rectangular chest to be:

= H(x) = x+6.

When the Area of rectangular chest:

A(x) = 20√x /3

Note that: Volume of chest = Base area  x Height

Therefore:

(X + 6) * 20√x /3

(20x√x /3 ) + (20 * 6√x/3)

(20x√x /3 ) + (20 * 2 * 3√x/3)

(20x√x/3) + 40√x

Therefore, the correct answer for the drop-down menu is that the first blank is multiply and the second blank is 40.

Answer:

8 1/2 cup servings

Step-by-step explanation:

Hello!

Well to solve this we have to take the total amount of cups of ice cream and divide it amongst the servings.

So :

Total = 4 cups

Serving = 1/2 cup

What we can do since its such a lower number is count it out by increments of 1/2.

Like so :

So, in total, there would be 8 servings of half a cup of ice cream in 4 cups.

I hope this helps!

If you have any questions or concerns feel free to message me or comment! :)

The number of 1/2 ­cup servings are in 4 cups of ice cream are 8.

A division is a process of splitting a specific amount into equal parts.

We need to find the number of 1/2 ­cup servings are in 4 cups of ice cream

A half cup serving is equal to 4 fluid ounces.

Therefore, 4 cups of ice cream is equal to 8 half-cup servings,

since 4 cups is equal to 32 fluid ounces and 32 divided by 4 equals 8.

4/(1/2)

4×2

8 cups

Hence, the number of 1/2 ­cup servings are in 4 cups of ice cream are 8.

Answer:

[tex]\angle L = 100^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]\angle G = 5^{\circ}[/tex]

[tex]\angle H = 75^{\circ}[/tex]

[tex]\angle L = 100^{\circ}[/tex]

Required

Determine the measure of L after reflection across x-axis

When a shape is reflected across an axis, only the coordinates of the shapes is affected; the angles remain unaltered.

In other words, the measures of the angle will not change.

Hence:

[tex]\angle L = 100^{\circ}[/tex]

2(3x-2) is the answer

The factors of the expression 6x + 4 will be 2 and (3x + 2).

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given as,

⇒ 6x + 4

Factorize the expression, then we have

⇒ 6x + 4

⇒ 2(3x + 2)

The factors of the expression 6x + 4 will be 2 and (3x + 2).
