The correct option regarding the number of bags filled by Nina, using proportions, is given as follows:

Between 20 and 30 bags.

A proportion is a fraction of an amount, and this fraction is combined with the unit rates of the problem and basic arithmetic operations, especially multiplication and division, to find the desired amounts in the context of the problem.

In this problem, a proportion is applied to find the number of bags filled by Nina, which is given by the division presented as follows:

Number of bags = Number of treats / Treats per bag.

The values of these parameters are given as follows:

Hence the numeric value of the expression is:

Number of bags = 78/3 = 26.

Which is a number between 20 and 30.

The problem states that Nina had 78 treats, and each bag has 3 treats, then it asks the correct option regarding the number of bags.

Answer:

Step-by-step explanation:

Here we have a dilation of scale factor 2.

We can see that bot figures we have the same slope, so we just have a dilation of scale factor K to go from figure A to figure B.

To find the value of K, notice that for some side length L in figure A, the correspondent length L' in figure B must be:

L' = K*L

Here if we use the left sides, we will get:

for figure A; L= 2

for figure B: L = 4

4 = K*2

4/2 = K

2 = K

So this is a dilation of scale factor k = 2.

The value of x in 7-3(2x-1)= 2x+26 is -4

Linear equation is is a mathematical statement, which has an equal sign (=) between the algebraic expression. Linear equations are the equations of degree 1. It is the equation for the straight line. The solutions of linear equations will generate values, which when substituted for the unknown values, make the equation true. In the case of one variable, there is only one solution. For example, the equation x + 3= 0 has only one solution as x = -3.

To find x in 7-3(2x-1)= 2x+26 ,we solve the parentheses first which will give

7- 6x+3= 2x+26

collect the like terms

-6x-2x=26-3-7

-8x= 16

divide both side by -8

-8x/-8= 16/-8

therefore x= -2

The value of d in the image that shows the two parallel lines that are crossed by the transversal is determined as: 125°.

In geometry, a transversal is a line that intersects two or more other lines at distinct points. When a transversal intersects a pair of parallel lines, it creates various angles and relationships between those angles.

The image attached below shows the two parallel lines which are crossed by the transversal, where angle d and 125° are vertical angles.

Since they are vertical angles, they will be equal or congruent to each other. Therefore, the value of d = 125°

Answer:

The total weight of the sugar and water  is 20 grams

Step-by-step explanation:

Given;

weight of sugar Maya added, w₁ = 6 grams

weight of water contained in the bottle, w₂ = 14 grams

The total weight of the sugar and water = 6 grams + 14 grams

The total weight of the sugar and water = 20 grams

Therefore, the total weight of the sugar and water in the bottle is 20 grams.

The possible perimeters are 140 feet, 148 feet and 160 feet.

In order to determine the width that would be used to determine the possible perimeters, the formula for the area would have to be rewritten.

A rectangle is a 2-dimensional quadrilateral with four right angles and two diagonals that bisect each other at right angles.

Area of a rectangle = length x width

Width = area / length

1200 / 40 = 30 feet

1200 / 50 = 24 feet

1200 / 60 = 20 feet

Perimeter of a rectangle = 2 x (length + width)

Perimeter when width is 30 feet : 2(40 + 30) = 140 feet

Perimeter when width is 24 feet : 2(24 + 50) = 148 feet

Perimeter when width is 20 feet : 2 (20 + 60) = 160 feet

Based on the system of equations, the cost of using 19 HCF of water is $35.43

An equation is a mathematical statement that two or more values are equivalent.

Equations are stated to show that two mathematical expressions are equal using the equation sign (=).

Cost of using 17 HCF of water = $32.13

Cost of using 35 HCF of water = $61.83

Total cost of 17 HCF water = 17x + a

17x + a = 32.13 ... equation 1

Total cost of 35 HCF water = 35x + a

35x + a = 61.83 ... equation 2

35x + a = 61.83

-17x + a = 32.13

18x = 29.70

18x = 29.7

x = 29.7/18

x = 1.65

17x + a = 32.13 ... equation 1

17(1.65) + a = 32.13

28.05 + a = 32.13

a = 4.08 (32.13 - 28.05)

= 19(1.65) + 4.08

= $35.43

Thus, using the equations above, we can conclude that 19 HCF of water costs $35.43.

Answer:

Step-by-step explanation:

the volume of a prism is always the base times the height this can be written as V = bh

we know the volume is 144 and the base is 24

substitute this into your equation: 144 = 24h

divide both sides by 24 to find h

144 ÷ 24 = 6

so you get h = 6

Assuming an oblique prism has a volume of 144 cubic units. The perpendicular height of the prism is 6 units.

Using this formula

Volume of prism=Base area ×Height

Hence:

144=24×h

h=144/24

h=6 units

Therefore, assuming an oblique prism has a volume of 144 cubic units. The perpendicular height of the prism is 6 units.

Answer:

Step-by-step explanation:

First, let us define what a set that is neither opened nor closed mean.

When we say a set of rational numbers is neither open nor closed. We are saying it isn't open because all the neighborhood of a rational number contains irrational numbers, and its complement isn't open either because all neighborhood of an irrational number contains rational numbers.

Now, a set that is neither open nor closed is a set that has an interval with one end open and one end closed, for example, [3, 4).

If we are to construct a sequence of open sets whose intersection is [3,4)

Then we say that:

Assume that G(n) = (-1/n, 1)

Then all G(n) contains [3,4).

Answer:

x is greater than -2 and less than or equal to 3

Step-by-step explanation:

so the 3x + 1 is greater than -5

so 3x is greater than -6

we divide both sides by 3

then we find out that x is greater than -2

we also know that 3x + 1 is less than or equal to 10

so 3x is less than or equal to 9

we divide both sides by 3

then we find out that x is less or equal to 3

so we can say that x is greater than -2 and less than or equal to 3

200.60 interest does andy’s account earn.

Let x be the amount of interest earned by Andy's account.

According to the problem, Andy's account earns 0.3% more interest than Marty's account, which means that Andy's account earns the same amount plus an additional 0.3% of that amount. Mathematically, we can express this as:

x = 200 + 0.3% of 200

Simplifying the right-hand side of the equation, we get:

x = 200 + 0.003 × 200

The solution to the system of equations is x = 2 and y = -8.

To solve the system of equations, we'll use the substitution method. The given equations are:

Equation 1: 8x + 5y = 24

Equation 2: y = -4x

We'll substitute Equation 2 into Equation 1 to eliminate one variable:

8x + 5(-4x) = 24

8x - 20x = 24   [Distribute the -4]

-12x = 24        [Combine like terms]

x = 24 / -12    [Divide both sides by -12]

x = -2

Now that we have the value of x, we can substitute it back into Equation 2 to find the value of y:

y = -4(-2)

y = 8

Therefore, the solution to the system of equations is x = -2 and y = 8.

However, let's double-check the solution by substituting these values into the original equations:

Equation 1: 8(-2) + 5(8) = 24

-16 + 40 = 24

24 = 24    [LHS = RHS, equation is satisfied]

Equation 2: 8 = -4(-2)

8 = 8       [LHS = RHS, equation is satisfied]

Both equations are satisfied, confirming that x = -2 and y = 8 is indeed the solution to the given system of equations.
