Answer:

If you solved this, it wouldn't have a remainder. First you would solve the numbers in the parenthesis, (15 - 3), which is 12. Now it should look like, 12 ÷ 12 + 1. Next you divide 12 by 12 and that equals 1. And all you need to do now is add 1 + 1, which is 2. So your answer will be 2.

Answer:

2

Step-by-step explanation:

To be able to solve this equation, you would use PEMDAS. This stands for the order of operations, and which order you would do them in.  P stands for parenthesis, E stands for exponents, M stands for multiplication, D stands for division, A stands for addition, and S stands for subtraction. Using this order, you would solve what is inside the parentheses first. So, 15-3 is 12. Once this piece is solved, you would have 12÷12+1. Then, since you don't have any exponents or multiplication, you would skip to division. 12 ÷ 12 is 1. So then your equation would be: 1+1. 1+1 is equal to 2. So your answer is 2! There is not remainder in the solution of this problem.

B. 54π yd^2

Step-by-step explanation:

On god it is right trust mee!    

Answer: Our required area is 54π sq. yd.

Step-by-step explanation:

Since we have given that

Diameter of an ice skating = 44 feet

Radius of an ice skating = 22 feet

as we know the formula for area :

Area would be

[tex]\pi r^2\\\\=\pi \times 22^2\\\\=484\pi\ ft^2[/tex]

As we know that

9 sq ft = 1 sq yd

So, it becomes,

[tex]\dfrac{484\pi}{9}=53.77\pi\ yd^2\approx 54\pi\ yd^2[/tex]

Hence, our required area is 54π sq. yd.

Answer:

2:5

Step-by-step explanation:

8:20 divided by 4 on bothe sides would equal 2:5

Equivalent ratios to 8:20 can be found by simplifying this ratio to its lowest terms, which is 2:5, and then scaling these numbers up or down by the same factor. Examples of equivalent ratios to 8:20 include 2:5, 4:10, 6:15, 8:20, and 10:25.

The question is asking for ratios equivalent to the ratio 8:20. To find equivalent ratios, we need to either multiply or divide both numbers in the ratio by the same amount. Ratios are a method of comparing quantities and numbers.

Let's start by simplifying the ratio 8:20 to its simplest form. To do this, we find the greatest common divisor of 8 and 20 which is 4. Then, divide both numbers by 4. This simplifies the ratio to 2:5.

Now that we have the simplified form of the ratio, we can find equivalent ratios by simply multiplying or dividing these numbers by any other number. For instance, multiplying by 2, we get the ratio 4:10. This is an equivalent ratio to 8:20 because the relationship between the numbers remains the same.

Here are some other equivalent ratios to 8:20: 6:15, because 2 x 3 = 6 and 5 x 3 = 15; 8:20, because 2 x 4 = 8 and 5 x 4 = 20; and 10:25, because 2 x 5 = 10 and 5 x 5 = 25.

Answer:

(4, 0 )

Step-by-step explanation:

A translation of 1 unit left, subtract 1 from the original x- coordinate

A translation of 2 units down, subtract 2 from the original y- coordinate

The rule is (x, y ) → (x - 1, y - 2 ), thus

(5, 2 ) → (5 - 1, 2 - 2 ) → (4, 0 )

The image point of (5,2) after a translation left 1 unit and down 2 units is (4, 0).

To find the image point of (5,2) after a translation left 1 unit and down 2 units, we need to subtract 1 from the x-coordinate and subtract 2 from the y-coordinate.

The translated image point would be (5-1, 2-2) = (4, 0).

So, the image point of (5,2) after the translation left 1 unit and down 2 units is (4, 0).

Answer:

Thus, to make 4 pecan pies one need to buy approximately 1.3 pounds of pecan.        

Step-by-step explanation:

We are given the following information in the question:

Number of pecan pies to be made = 4

Pecan required to make 1 pie = [tex]1\frac{1}{2} \text{ cups}[/tex]

Pecan required to make 4 cups =

[tex]4\times 1\frac{1}{2} = 4\times \frac{3}{2} = 6\text{ cups}[/tex]

Now, 1 bag of pecan has a serving size of 1 cup . Hence, we need to buy 6 such bag.

Now, weight of one bag = 99 grams

Weight for 6 cups of pecan = [tex]6\times 99 = 594\text{ grams}[/tex]

We know that:

1 gram = 0.00220462 Pounds

594 grams of pecans = [tex]594\times 0.00220462 =1.30954428 \text{ pounds of Pecan}[/tex]

Thus, to make 4 pecan pies one need to buy approximately 1.3 pounds of pecan.

To solve this problem, first determine the information you need to answer. As we need to make 4 pecans of the pies, take the values for the one piece and multiply it with four.

To make 4 pecans pies one will required to by 1.30 pounds of pecan.

Given information:

Number of pecan pies to be made is 4

The pecan needed to make 1 pie is [tex]1.5[/tex]  cups.

Now, Pecan required to make 4 cups will be:

[tex]4 \times 1.5 = 6[/tex] cups.

As, 1 bag of pecan has a serving size of 1 cup

Hence, we need 6 such bags.

Now, weight of the bag is 99 grams

so,

weight of 6 such bags will be

[tex]=6\times 99\\=594 \;\text{gm}[/tex]

And we have

[tex]1 \; \text{gm}=0.00220462 \; \text{pound}[/tex]

So,

594 grams of pecans = [tex]594\times 0.00220462[/tex]

[tex]=1.3095 \;\text{pounds}[/tex]

Hence, to make 4 pecans pies one will required to by 1.30 pounds of pecan.

To solve -5/6 + (-1/12), convert both to have a common denominator of 12, resulting in -10/12 + (-1/12). Add the numerators to get -11/12. The sum of two negative fractions maintains a negative sign.

To find the answer to the problem -5/6 + (-1/12), we need to add the two fractions. When adding fractions with different denominators, we first find a common denominator. In this case, the common denominator for 6 and 12 is 12. We then convert each fraction to an equivalent fraction with this common denominator.

For the first fraction -5/6, we multiply both the numerator and the denominator by 2 to get -10/12. The second fraction is already with a denominator of 12, so we keep it as -1/12. Now, we add the numerators while keeping the denominator the same:

-10/12 + -1/12 = -11/12. The sum of the two fractions is -11/12, which is already in simplest form.

This example demonstrates that when two negative numbers add, the answer has a −ve sign, and the numerators are simply added together while the denominator remains the same.

[tex]KCC=18+29[/tex]

[tex]18+29=47[/tex]

Option A -18 + 18 = 0

Option B +29 + +18 = 47

Option C -18 - +29 = -18 + -29 = -47

Option D -29 - -18 = -29 + 18 = -11

Therefore your answer is option B.

Answer:

1 2/7 cups of sugar

Step-by-step explanation:

You can use a proportion.

To make it easier to write the proportion, we rewrite the numbers as decimals.

3 1/2 = 3.5

3/4 = 0.75

Let x be the unknown amount of sugar.

3.5 cups of flour is to 0.75 cup of sugar as 6 cups of flour is to x cups of sugar.

3.5/0.75 = 6/x

Cross multiply.

3.5x = 0.75 * 6

3.5x = 4.5

x = 4.5/3.5 = 45/35 = 9/7 = 1 2/7

Answer:

The value of x is [tex](+/-)\sqrt{6}[/tex]

Step-by-step explanation:

The question in English is

Find the value of x so that the distance between the given points is 2V5 units.

(2x - 1,2) and (1 + x,x + 4)

we know that

the formula to calculate the distance between two points is equal to

[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]

substitute the values

[tex]d=\sqrt{(x+4-2)^{2}+(1+x-2x+1)^{2}}[/tex]

[tex]d=\sqrt{(x+2)^{2}+(-x+2)^{2}}[/tex]

[tex]d=\sqrt{x^2+4x+4+x^2-4x+4}[/tex]

[tex]d=\sqrt{2x^2+8}[/tex]

Remember that

[tex]d=2\sqrt{5}\ units[/tex]

substitute

[tex]2\sqrt{5}=\sqrt{2x^2+8}[/tex]

squared both sides

[tex]20=2x^2+8\\\\2x^{2}=12\\\\x^{2}=6\\\\x=(+/-)\sqrt{6}[/tex]

  - Multiplication equation: [tex](3)(7)=21[/tex]

  -  How are the equation related? Each equation shows 3 groups of 7.

Step-by-step explanation:

We know that Jan buys 3 bags of beads and each bag contains 7 beads, then, you can draw the bar diagram shown attached.

 Observe that the diagram has 3 blocks (each block represents a bag of bead) and there is a number 7 inside of each block (which is the number of beads contained in a bag).

Therefore:

- Add the numbers inside the blocks in order to get the addition equation that shows the number of  beads Jan buys. This is:

[tex]7+7+7=21[/tex]

- Multiply 3 blocks by 7 in order to get multiplication equation that show the number of beads Jan buys:

[tex](3)(7)=21[/tex]

The equations are related. Each one shows 3 groups of 7.

Answer:

n=68

Step by step explanation:

When a number n is increased by two means n+2 so we can put parenthesis around it

(n+2)/5 = 14  

now we solve for the equation (for the variable n)

First multiply both sides by 5 to isolate the parenthesis on the left side by itself

(n+2) = 14*5

then we can simply isolate n by itself by subtracting both sides by 2

n = 70 -2 = 68

n = 68

To find the value of n when [tex]\frac{(n + 2) }{5}[/tex]  = 14,  resulting in n = 68.

The question asks to define an equation based on a described operation with a given result, and then solve it to find the value of n. The operation described is increasing a number n by two, then dividing the result by five to get a quotient of 14.

To translate this into an equation, you would set up the following equation:

[tex]\frac{(n + 2) }{5}[/tex] = 14

To find the value of n, you would first multiply both sides by 5 to isolate n on one side:

n + 2 = 70

Then, subtract 2 from both sides to solve for n:

n = 68

Therefore, the value of n is 68. This solves the equation and provides the value that n must be for the operation to result in a quotient of 14.

Answer:

1) The question is aimed to determine the number that Laura is trying to come up with.

Such question is solved by stating an algebraic equation from the word statement, which is done step by step.

2) Using the name x for the unknown, the expression "three less than 8 times the number" is translated to: 8x - 3

3) The expression "half of 16 times the number after it was increased by 1" is translated to: (1/2) (16x + 1)

4) Finally, since they are equal, you can set the equation:

8x - 3 =  (1/2) (16x + 1)

5) And solve for x in this way:

i) Distributive property:

8x - 3 = 8x + 1/2

ii) At this stage you can see that the both 8x terms (on the left and on the right) cancel each other, which leads to the impossibility to determine the value of the unknown:

-3 = 1/2 which is alwasy false, meaning that the equation has no solution.

Laura can’t find a number that works because the equation is inconsistent and has no solution.

In order to solve this word problem, we would assign a variable to the unknown number, and then translate the word problem into an algebraic equation as follows:

Let the variable n represent the unknown number.

Based on the statement "Three less than eight times the number is equal to half of 16 times the number after it was increased by one," we can logically deduce the following algebraic equation;

8n - 3 = 1/2 × (16n + 1)

16n - 6 = 16n + 1

16n - 16n = 1 + 6

0 = 7 (False).

Therefore, this equation has no solution because the coefficients are the same on both sides.

Step-by-step explanation:

If Chad had 7 sandwiches and that was 6 fewer than the amount Sarah has then Sarah made 6 sandwiches. The working is as follows :

Chad = 7 sandwiches (6 fewer than Sarah)

Sarah = ?

Sarah = 7 + 6 = 13 sandwiches.

In order for Chad to have eaten that many sandwiches, Sarah would have had to have made 13 sandwiches.

Sarah made x number of sandwiches and Chad ate 7 out of it.

The 7 that Chad ate remained 6 sandwiches out of the total that Sarah made.

The number of sandwiches Sarah made is therefore:

= Number that Chad ate + Number that was left

= 7 + 6

= 13 sandwiches

In conclusion, Sarah made 13 sandwiches
