We can start off by making 12 1/2 to an improper fraction:

12 1/2 = 25/2

Divide the large jar of salsa by the small jar of salsa: 75 /  25/2.

Reciprocal of second and turn divide to multiply:

75 * 2/25.

150/25 =  6.

So 6 jars of small salsa = 1 large jar of salsa.

The solution set is (7,3).

Answer:

40.43 Kilometers

Explanation:

19.16, 13, 8.27

19.16 + 13 + 8.27

= 40.43

Final answer:

The total distance Kira ran during the three days is the sum of the individual distances she ran on each day, which is 40.43 kilometers.

Explanation:

The total distance Kira ran on the three days is the sum of the distances she ran on each day. To find the total distance, you simply need to add up the three individual distances.

Add the first distance: 19.16 km

Add the second distance: 13 km

Add the third distance: 8.27 km

Calculate the sum: 19.16 km + 13 km + 8.27 km = 40.43 km

Therefore, the total distance Kira ran during the three days is 40.43 kilometers.

The value of 9 × 9 is 81.

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

The question is to find the product of 9 × 9.

By the definition of multiplication, 9 × 9 is the addition of the number up to 9 times.

That is, 9 × 9 can also be written as,

9 × 9 = 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9

Adding number 9 to itself 9 times we get 81.

So 9 × 9 = 81

Hence the product after multiplying 9 with 9 is 81.

Answer:

A

Step-by-step explanation:

Consider Δ JKL and Δ GDF

If the ratios of corresponding sides are equal then the triangles are similar.

[tex]\frac{JK}{GD}[/tex] = [tex]\frac{24}{20}[/tex] = [tex]\frac{6}{5}[/tex]

[tex]\frac{xJL}{GF}[/tex] = [tex]\frac{18}{15}[/tex] = [tex]\frac{6}{5}[/tex]

[tex]\frac{KL}{DF}[/tex] = [tex]\frac{12}{10}[/tex] = [tex]\frac{6}{5}[/tex]

Since the ratios are equal then Δ JKL and Δ GDF are similar by SSS postulate.

Area of the figure is 532 m².

Solution:

In the given image the shape is splitted into 2 shapes.

First shape is the square.

In square 4 sides are equal.

Area of the square = side × side

                               = 18 m × 18 m

Area of the square = 324 m²

Second shape is the triangle in the bottom.

Base of the triangle = 18 m + 8 m = 26 m

Height of the triangle = 16 m

Area of the triangle = [tex]\frac{1}{2}\times{\text{base}}\times{\text{height}}[/tex]

                                 [tex]$=\frac{1}{2}\times16\times26[/tex]

Area of the triangle = 208 m²

Area of the given shape = area of the square + area of the triangle

                                         = 324 m² + 208 m²

Area of the given shape = 532 m²

Hence area of the figure is 532 m².

Final answer:

In a 45-45-90 triangle, with a hypotenuse of 2√14, both legs x and y are equal and their lengths can be found by dividing the hypotenuse by √2, which results in lengths of √14 for each leg.

Explanation:

In a 45-45-90 triangle, also known as an isosceles right triangle, the legs are of equal length and the hypotenuse is √2 times the length of one leg. If the hypotenuse is given as 2√14, we can use the fact that the hypotenuse is √2 times the length of a leg to find the length of the legs x and y.

Let x represent the length of one leg and y represent the length of the other leg. Since the triangle's legs are equal in this special triangle, x = y. The relationship between the legs and the hypotenuse in a 45-45-90 triangle can be expressed using the Pythagorean Theorem:

x² + y² = hypotenuse²

Solving for x and y, we get:

x = y = hypotenuse/√2 = (2√14)/√2 = √14

Therefore, in a 45-45-90 triangle with a hypotenuse of 2√14, both x and y, which are the lengths of the legs, are √14.

Answer: x= -1 y= 4

Step-by-step explanation:

We are going to solve this using substitution.

Here is the work...

5x+3(4)=7

That is what it woud look like because y is equal to 4.

3 times 4 is 12.

So now we have...

5x+12=7

Now we want to get All the common factors together...

To do this we will subtract 12 from 7 and we get -5.

Here is our equation now...

5x=-5

Now we divide x by 5 to get x alone, but we also divide -5 by 5.

x=-1

Now all we have to do to solve for y is put x in an equation.

In this case here is what we will do...

5(-1)+3y=7

Multiply...

-5+3y=7

Now we need to get the common factors together so lets add 5 to 7.

3y=12

3y/3=y

12/3=y

y=4

But that is already in your problem...OOF.Dont worry its still correct.

To solve the system, substitute y=4 into the first equation, leading to x=-1. Thus, the solution is x=-1 and y=4.

To solve the system of equations 5x + 3y = 7 and y = 4, we can start by substituting the value of y from the second equation into the first equation. We are given y directly, so the substitution is straightforward.

Substituting y = 4 into the first equation:

So, the solution to the system of equations is x = -1 and y = 4. We can say that x and y are variables, and in this case, y is dependent on x in other linear equations but is given directly here.

Answer: P(A|B) = 0.40.

Step-by-step explanation: Since A and B are independent events, P(A|B) = P(A).

Therefore, P(A|B) = 0.40.

The probability of A given B is 0.40.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

Since A and B are independent events, we know that:

P(A and B) = P(A) x P(B)

But since they are independent, we also know that:

P(A and B)

= P(A) x P(B|A)

= P(B) x P(A|B)

Thus:

P(A|B) = (P(A) x P(B|A)) / P(B)

We are given that P(A) = 0.40 and P(B) = 0.30.

We don't know P(B|A), but since A and B are independent, we know that:

P(B|A) = P(B)

So,

P(A|B) = (0.40 x 0.30) / 0.30 = 0.40

Thus,

The probability of A given B is 0.40.

[tex]21+7.50p\leq 52[/tex]

For inequalities, "a is no more than b" can be written as:

[tex]a\leq b[/tex]

Here we know Candace that can spend no more than $52 before tax. She can spend a certain amount of money in both Dark Roast coffee and Morning Blend coffee. So she spends:

Therefore:

Amount of money for Morning Blend coffee:

[tex]2\times 10.50=\$21[/tex]

Amount of money for Dark Roast coffee:

[tex]p\times 7.50=\$7.50p[/tex]

So the total amount of money:

[tex]21+7.50p[/tex]

Finally, the inequality becomes:

[tex]21+7.50p\leq 52[/tex]

Besides, in order to know how many pounds she can spend let's solve for p:

[tex]7.50p\leq 52-21 \\ \\ 7.50p\leq 31 \\ \\ p\leq 4.13[/tex]

Final answer:

The correct inequality to determine the possible values for the number of pounds of Dark Roast coffee, p, along with 2 pounds of Morning Blend coffee for $52 or less is 9p + 15.10 ≤ 52. This inequality can be used to solve for p, the number of pounds of Dark Roast coffee Candace can buy which is p ≤ 4.1.

Explanation:

Calculator Candace wants to determine the number of pounds of Dark Roast coffee, represented as p, she can buy if she purchases 2 pounds of Morning Blend coffee for a total of $52 or less. The price of the Morning Blend coffee is $7.55 per pound. To calculate this, we need to create an inequality that represents the scenario:

Now, the inequality will consider the total price of the Morning Blend coffee and add the price of the Dark Roast coffee (which is $9.00 per pound). So the inequality should look like this:

9p + 15.10 ≤ 52

This inequality can be used to solve for p, the number of pounds of Dark Roast coffee Candace can buy which is p≤4.1.

Answer:

look at the picture shown

Answer:

14 and 25

Step-by-step explanation:

x = smaller number

y = larger number

x + y = 39

x = y - 11

now we sub

y - 11 + y = 39

2y - 11 = 39

2y = 39 + 11

2y = 50

y = 50/2

y = 25 <=== larger number

x = y - 11

x = 25 - 11

x = 14 <==== smaller number

The problem can be solved by setting up and solving two algebraic equations. The two numbers in question are 25 and 14.

The subject of this problem is algebra. To solve it, we can set up two equations based on the problem's statements, and then solve those equations.

First, we know that the sum of two numbers is 39, so we can write that as: x + y = 39 (Equation 1).

Second, we know that the smaller number is 11 less than the larger number. Assuming x is the larger number and y is the smaller one, we can write this as: y = x - 11 (Equation 2).

To solve these equations in parallel, insert Equation 2 into Equation 1, that results in: x + (x - 11) = 39. Solving this equation simplifies to 2x = 50, so x = 25. Substitute x = 25 in Equation 2, we get: y = 25 - 11 = 14. So, the two numbers are 25 and 14.
