Answer:

Samuel uses 1 11/12 cups of flour.

Step-by-step explanation:

Okay, this is assuming he uses the rest of the flour she didn't use.

The first step would be to find the Greatest Common Factor(GCF) of the fractions

2 1/4 and 1/3 have different denominators, but they both can divide into 12.

1/4 * 3/3 = 3/12

1/3 * 4/4 = 4/12

Now we can also convert 2 3/12 into an improper fraction to make it easier

2* 12/12 = 24/12

24/12+ 3/12 = 27/12

Here's the part were we subtract the two numbers.

27/12- 4/12 = 23/12

The last step is to simplify the fraction

23/12 = 1 11/12 cups

Step-by-step explanation:

If you're square is a true square, than the height and base will be the same. If one is larger than the other, it's a rectangle.

If you slice a square diagonally, you still have the original height of the square.

Final answer:

To find the ratio of the triangle's height to the square's side, set the area of the triangle (1/2 × base × height) to be twice that of the square (side²). Simplify by equating base to side as they are the same length and solve for the height. The resulting ratio of the height of the triangle to the side of the square is 4:1.

Explanation:

The question involves finding the ratio of the height of a triangle to the side of a square where the area of the triangle is twice that of the square, and they have one side in common. The area of a square is given by side² (s²), and the area of a triangle is given by 1/2 × base × height (1/2 × b × h). To solve this, we set the triangle's area to be twice the square's area: 1/2 × b × h = 2 × s². Since the base of the triangle (b) is equal to the side of the square (s), they can be represented by the same variable. Hence, the equation simplifies to 1/2 × s × h = 2 × s². Canceling s from both sides leaves us with h = 4 × s. Therefore, the ratio of the height of the triangle to the side of the square is 4:1.

Step-by-step explanation:

To make the statement '17/20 ? -11.95' true, the correct symbol to use is '>'. We find this by comparing the result of 17 divided by 20 (which is 0.85) with -11.95.

The question is asking us to find the correct sign (either less than '<', equal '=', or greater than '>') to make the mathematical statement '17/20 ? -11.95' true.

To solve this, we first need to divide 17 by 20 to get 0.85. Then, we compare this result with -11.95.

Since 0.85 is greater than -11.95, we use the '>' symbol. Thus, the statement '17/20 > -11.95' is true.

Assuming that we are solving in terms of n.

Start by distributing:

2(n + 5)

(2*n) + (5*2)

2n + 10 = -2

Subtract 10 to start toward isolating your variable:

2n = -12

Divide by two to finish solving:

n = -6

Answer:

n=-6

Step-by-step explanation:

2(n+5)=-2

distribute the 2 to the numbers in the parentheses:

2n+10=-2

Get the n factor alone, subtract 10 from both sides:

2n=-12

Now you just want the n alone so you are going to use the inverse operation on 2n to both sides: 2n/2=-12/2

n=-6

Answer:

Figure (i) and (iv)

Step-by-step explanation:

We need to find two figures that are similar to the 5 by 10 figure.

that is we need to find the figure that is similar to 5 X 10 figure.

Observe that in a figure m X n, the letter m represent the number of rows and the letter n represents the number of columns.

Observe that in the given figure 5 by 10, the number of rows is 5 and number of columns is 10, that is, the number of columns is double of that the number of rows.

so we need to find two such figures whose number of columns is double of the number of rows.

from the given figures, we can see that in the figure (i) the number of rows is 2 and number of columns is 4, which is double of number of rows. so it is similar to 5 by 10 figure.

And the figure in (iv), the number of rows is 4 and number of columns is 8. so here since the number of columns is double the number of rows, so it is similar to the figure 5 by 10.

Thus the two figures that are similar to 5 by 10 figure are given in (i) and (iv).

The two figures that share a similarity with the 5 by 10 figure based on the doubling relationship between columns and rows are represented by options (i) and (iv).

In the provided 5 by 10 figure, it's evident that the number of columns is twice the number of rows.

Therefore, our goal is to identify two other figures with the same relationship.

Upon examination of the given options, we can see that in figure (i), there are 2 rows and 4 columns, which maintains the same doubling relationship between columns and rows as the 5 by 10 figure.

Thus, figure (i) is similar to the 5 by 10 figure.

Similarly, in figure (iv), there are 4 rows and 8 columns, and this also maintains the doubling relationship between columns and rows. Therefore, figure (iv) is another figure similar to the 5 by 10 figure.

In summary, the two figures that share a similarity with the 5 by 10 figure based on the doubling relationship between columns and rows are represented by options (i) and (iv).

The perimeter of the rectangle is 42m.

To find the perimeter of the rectangle, we need to know the lengths of its sides. From the given information, we know that the area of the rectangle is 108m^2 and its diagonal is 15m. We can use this information to find the lengths of the sides.

Let the length of the rectangle be 'l' and the width be 'w'.
Given, lw = 108 and sqrt(l^2 + w^2) = 15.
Squaring both sides of the second equation, we get l^2 + w^2 = 225.
Since lw = 108, we can solve the quadratic equation l^2 - 108l + 225 = 0 to find l. In this particular case, the quadratic factors as (l - 9)(l - 12) = 0, so l = 9 or l = 12.
Substituting the values of l in the equation lw = 108, we find w = 12 or w = 9.
Since the perimeter is the sum of all the sides, the perimeter of the rectangle is (2l + 2w) = (2 * 9 + 2 * 12) = 42m.

Step-by-step explanation:

We are given the co-ordinates,

x : -2, -1, 0, 1, 2

y : 8, 5, 2, -1, -4

According to the graph, we see that this function represents a straight line.

The general form of the straight line is y = mx + c, where m is the slope and c is the y-intercept.

So, taking any two points we will find the equation of the straight line.

Consider, (0,2) and (1, -1). Now, slope is given by,

m = [tex]\frac{-1-2}{1-0}[/tex]

i.e. m = -3

Now, we will find the y-intercept of this equation using (0,2) and m = -3,

i.e. y = -3x + c

i.e. 2 = c

Hence, the equation of the straight line is y = -3x + 2.

The equation representing the total cost after buying x slices of pizza

is [tex]\( C(x) = E + x \times P \)[/tex].

Let's denote the entrance fee as E (in dollars) and the cost of each slice of pizza as P (also in dollars). Given the problem, we can write the following equations based on the given information:

After having 1 slice of pizza, the total cost is $6:

[tex]\(E + 1 \times P = 6\)[/tex]

After having 2 more slices of pizza (total 3 slices), the total cost is $10:

[tex]\(E + 3 \times P = 10\)[/tex]

To find the equation that represents the total cost (y) after buying x slices of pizza (let's call it C(x), we need to generalize the pattern observed in the given equations.

Notice that the entrance fee remains constant regardless of the number of slices of pizza bought. So, we can write the equation as:

[tex]\[ E + x \times P = C(x) \][/tex]

Substituting the values given in the problem:

[tex]\[ C(x) = E + x \times P \][/tex]

So, the equation representing the total cost after buying x slices of pizza

is [tex]\( C(x) = E + x \times P \)[/tex]. This equation gives the total cost (y) as a function of the number of slices of pizza bought (x).

BC = 6.7 cm (rounded to nearest tenth)

Explanation:

Given: ABC is a right triangle with right angle C as shown below.

Side AB=18 cm and m∠A=22°.

Using Sine ratio in triangle ABC to find BC.

Sine ratio is defined as the ratio of the opposite side of a right triangle to the hypotenuse.

i.e

[tex]\sin A = \frac{Opposite side}{Hypotenuse side}[/tex]

Let BC = x (opposite side) and AB = 18 cm(Hypotenuse side)

then;

 [tex]\sin 22^{\circ} = \frac{x}{18}[/tex]

[tex]0.37460659341 = \frac{x}{18}[/tex]

Multiply both sides by 18 we get;

[tex]x = 0.37460659341 \times 18 = 6.74291868[/tex]

therefore, value of BC (nearest tenth place) is, 6.7 cm
