Step-by-step explanation:

3m + 3m + 12m + 3m + 3m + 14m + 18m + 14m

The reason I added 18m in there is because the bottom line is 18m. If the top line is 12m, then you add 3m on each side, making it 18m.

Answer:

$41.67

Step-by-step explanation:

To save at least $500 in 12 months, Daksha must save an average of at least $500/12 = $41.67 per month.

To find the minimum amount she must save each month, we can assume she saves a constant amount each month, and solve for that amount.

Let x be the amount she saves each month. Then over 12 months, she will have saved 12x dollars. To meet her goal of saving at least $500, we need:

12x ≥ 500

Solving for x, we get:

x ≥ 500/12

x ≥ 41.67

Therefore, Daksha must save at least $41.67 each month to save at least $500 in 12 months.

Answer:

a. The area of a triangle is given by the formula A = (1/2)bh, where b is the base and h is the height. We know that A = 46cm^2 and b = 23cm. Substituting these values into the formula, we get:

46cm^2 = (1/2)(23cm)(h)

Simplifying, we get:

46cm^2 = 11.5cm*h

Dividing both sides by 11.5cm, we get:

h = 4cm

Therefore, the missing side of the right triangle is 4cm.

b. Using the same formula, we can find the height of the triangle:

120cm^2 = (1/2)(40cm)(h)

Simplifying, we get:

120cm^2 = 20cm*h

Dividing both sides by 20cm, we get:

h = 6cm

Therefore, the missing side of the right triangle is 6cm.

c. Again, using the same formula, we can find the height of the triangle:

12m^2 = (1/2)(20m)(h)

Simplifying, we get:

12m^2 = 10m*h

Dividing both sides by 10m, we get:

h = 1.2m

Therefore, the missing side of the right triangle is 1.2m.

Answer:

21

Step-by-step explanation:

You probably know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.

Here's a little tip for you. Any number can be converted to a fraction if you use 1 as the denominator:

36/1

So now that we've converted 36 into a fraction, to work out the answer, we put the fraction 7/12 side by side with our new fraction, 36/1 so that we can multiply those two fractions.

That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:

7/12 x 36/1 = 252/12

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 252 and 12 is 12.

We can now divide both the new numerator and the denominator by 12 to simplify this fraction down to its lowest terms.

252/12 = 21

12/12 = 1

When we put that together, we can see that our complete answer is:

21/1

The complete and simplified answer to the question what is 7/12 of 36 is:

21

Answer:

4ft high

Step-by-step explanation:

Answer: The actual length of the swing set area of the park is 25 ft long and 100 ft wide.

For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.

Then it means

All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.

For the given case, it is given that Real dimension of a rectangular park: 600 ft by 1000 ft In drawing, it was of 12 inches by 20 inches. Let the scale that the drawing is using be k feet to s inches, then.

Since it is given that 600 ft: 12 inches and 1000 ft: 20 inches, thus, we get: Thus, every foot is reduced 0.02 times in drawing.

Now, it is given that in drawing, the rectangular area for swing sets is 0.5 inch to 2 inch. Let its real length was L and real width was W. Then we have:

Since these are only magnitudes, and unit was converted from feet to inches, so we have L = 25 feet and W = 100 feet

Thus, the actual length of the swing set area of the park is 25 ft long and 100 ft wide

Answer:

The dimensions of the park on the scale drawing is 12 inches and 20 inches.

Dimension

Actual dimensions:

Park = 600 feet by 1000 feet

Swing set = 25 feet by 100 feet

Swing set on the scale drawing= 0.5 inch by 2 inches

Hence:

Dimension of park on drawing:

Width =  600×1/50

Width = 12inches

Length = 1000×1/50

Length= 20inches

Inconclusion the dimensions of the park on the scale drawing is 12 inches and 20 inches.

23.45+3.625

=27.075L

therefore, quantity of resultant mixture is 27.075 Liter

Answer:

Since Alex only has 5 cups of strawberries, he does not have enough to make both recipes.  

Step-by-step explanation:

1 3/4 cups of strawberries + 3 1/2 cups of strawberries= 5 1/4 cups of strawberries. Alex needs more strawberries.

Answer:

No.

Step-by-step explanation:

To solve the Yes/No question,

First, write the equation:

5 = [tex]1\frac{3}{4}[/tex] + [tex]3\frac{1}{2}[/tex]

Then convert the mixed fraction to improper ones:

5 = [tex]\frac{7}{4}[/tex] + [tex]\frac{7}{2}[/tex]

Then find the LCM of the denominators 4 & 2 ( = 4 ) and solve:

5 = [tex]\frac{7}{4}[/tex] + [tex]\frac{14}{4}[/tex]

5 = [tex]\frac{7+14}{4}[/tex]

5 = [tex]\frac{21}{4}[/tex]

5 = 5.25

5 < 5.25

So because 5.25 is greater than 5, he doesn't have enough strawberries to make the recipes.

Answer:

To determine whether the relation is a function or not, we need to check if each input value (x) is associated with exactly one output value (y).

Looking at the given set of points (-5, 1), (-3, 0), (0, -3), (2, 3), (5, -1), and (5, 1), we can see that some of the input values are associated with more than one output value. Specifically, the input value of 5 is associated with two different output values: -1 and 1.

Therefore, the relation is not a function because there is not exactly one output value for each input value.

The correct answer is: No, because for each input there is not exactly one output.

Answer:

Step-by-step explanation:

Part A:  step 1 is correct, step 2 is wrong.  Right side of the equation should be 12 - 21 = -9

Part B:

-14x + 21 = 30x + 12

-14x - 30x = 12 - 21

-44x = -9

x = -9/-44 = 9/44

Step-by-step explanation:

To calculate the probability of home and away wins, we need to know how many wins the team had at home and away, respectively.

Let's assume that the team won x games at home and y games away, where x and y are unknown variables. Then we know that:

x + y = total number of wins (which we'll denote as W)

x + (12 - y) = 12 (the number of home games)

(12 - x) + y = 12 (the number of away games)

Solving these equations for x and y, we get:

x = (W + 12) / 2 - 12

y = (W + 12) / 2 - 12

Now, let's say the team won 8 games in total. Then, using the equations above, we can calculate that:

x = 2 (i.e., they won 2 games at home)

y = 6 (i.e., they won 6 games away)

Therefore, the probability of a home win is 2/12 = 1/6, and the probability of an away win is 6/12 = 1/2.

Based on these calculations, Sasha is correct in her belief that the team plays better away. The probability of an away win is higher than the probability of a home win.

Step-by-step explanation:

Pi (π) is a mathematical constant representing the ratio of a circle's circumference to its diameter. It is an irrational number, which means it cannot be expressed as a finite decimal or a fraction. Therefore, it is not possible to solve for pi in the traditional sense.

However, pi can be approximated to a certain number of decimal places using various mathematical methods, such as the Monte Carlo method or numerical integration. The commonly used approximation for pi is 3.14159265358979323846, but the actual value of pi has an infinite number of decimal places and cannot be fully calculated.

Answer:

You can't

Step-by-step explanation:

Pi is already a constant rate if that is what you want to call it. pi is 3.14159265359

The number of solutions which the system of linear equations represented in the graph have is: B. No solution.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would find the slope of this lines;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (3 - 2)/(3 - 0)

Slope (m) = 1/3

At data point (0, 2) and a slope of 1/3, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y = x/3 + 2

At data point (0, -1) and a slope of 1/3, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y = x/3 - 1
