SOLVE FOR y

8x-12y=24

Answer:

Bowl B contains 2 apples more than Bowl A and Bowl A contains 1 mango more than Bowl B.

Step-by-step explanation:

Number of apples in Bowl A = 6

Number of mangoes in Bowl B = 8

Difference in apples = 8 - 6 = 2

So, Bowl B contains 2 apples more than Bowl A.

Number of mangoes in Bowl A = 3

Number of mangoes in Bowl B =2

Difference in mangoes = 3 - 2 = 1

So, Bowl A contains 1 mango more than Bowl B.

Bowl B has 2 more apples and 1 fewer mango compared to Bowl A. Thus, the primary differences are in the quantities of apples and mangoes in each bowl.

Step by Step Solution:

To understand the differences between Bowl A and Bowl B, let's break down the contents of each bowl:

Bowl A contains 6 apples and 3 mangoes.

Bowl B contains 8 apples and 2 mangoes.

Now, let's find the differences in the number of apples and mangoes between the two bowls:

Difference in Apples: Bowl B has 8 apples, and Bowl A has 6 apples. Therefore, the difference is 8 - 6 = 2 apples. Bowl B has 2 more apples than Bowl A.

Difference in Mangoes: Bowl A has 3 mangoes, and Bowl B has 2 mangoes. Therefore, the difference is 3 - 2 = 1 mango. Bowl A has 1 more mango than Bowl B.

In summary, Bowl B has 2 more apples and 1 fewer mango compared to Bowl A.

[tex]x=7.5[/tex]

Step-by-step explanation:

If you look at the large triangle, you will see that the side [tex]x[/tex] is opposite of 30° angle and the side 15 is opposite of 90° angle (side opposite of 90° angle is called the hypotenuse).

We have the angle, we have the side opposite and the hypotenuse. Which trigonometric ratio relates opposite side and hypotenuse? SINE!

So we use the sin ratio and cross multiply and solve for [tex]x[/tex]:

[tex]Sin(A)=\frac{Opposite}{Hypotenuse}\\Sin(30)=\frac{x}{15}\\x=15*Sin(30)\\x=15*(0.5)\\x=7.5[/tex]

Hence, [tex]x=7.5[/tex]

Answer:

a=3.75 un., b=11.25 un.

[tex]x=7.5\ un.[/tex]

[tex]y=\dfrac{15\sqrt{3}}{4}\ un.[/tex]

[tex]z=\dfrac{15\sqrt{3}}{2}\ un.[/tex]

Step-by-step explanation:

Given triangle is special 30°-60°-90° right triangle. The leg that is opposite to the angle of measure 30° is always equal to half of the hypotenuse. The hypotenuse is of length 15 units, the leg that is opposite to the 30° angle is leg with length of x units, then

[tex]x=\dfrac{15}{2}=7.5\ un.[/tex]

In right triangle with hypotenuse x and legs y and a, angle opposite to the leg a is 30°, then

[tex]a=\dfrac{x}{2}=\dfrac{7.5}{2}=3.75\ un.[/tex]

and

[tex]b=15-a=15-3.75=11.25\ un.[/tex]

By the Pythagorean theorem,

[tex]x^2=y^2+a^2,\\ \\7.5^2=3.75^2+y^2,\\ \\y^2=\left(\dfrac{15}{2}\right)^2-\left(\dfrac{15}{4}\right)^2=\dfrac{225}{4}-\dfrac{225}{16}=\dfrac{675}{16},\\ \\y=\dfrac{15\sqrt{3}}{4}\ un.[/tex]

In right triangle with legs y and b and hypotenuse z, leg y is opposite to 30° angle, then

[tex]z=2y=\dfrac{15\sqrt{3}}{2}\ un.[/tex]

Answer:

2 pens

Step-by-step explanation:

Let x represent the number of pens Linda buys.  Since they cost $2.65 each, this gives us the expression 2.65x.

Adding the cost of the card to this gives us the expression 2.65x+1.17.

She has a total of $9.00; this gives us the equation

2.65x+1.17 = 9.00

Subtract 1.17 from each side:

2.65x+1.17-1.17 = 9.00-1.17

2.65x = 7.83

Divide both sides by 2.65:

2.65x/2.65 = 7.83/2.65

x = 2.95

We cannot buy a portion of a pen, so the most she can buy is 2 pens.

Answer:

The answer is 2 pens.

Step-by-step explanation:

Total amount Linda has in her wallet = $9

Amount spent on buying a card = $1.17

So, amount left with Linda = [tex]9-1.17=7.83[/tex]

Now, she wants to buy pens that cost $2.65, so the maximum number of pens she can buy are = [tex]\frac{7.83}{2.65}= 2.9[/tex]

But, pens cannot be in decimal, so the maximum pens she can buy are 2.

Step-by-step explanation:

we are given equation as

[tex]2x^2-12x=-6[/tex]

Since, we have to solve it by using complete square

so, firstly we will complete square

and then we can solve for x

step-1:

Factor 2 from both sides

[tex]2(x^2-6x)=-3\times 2[/tex]

step-2:

Simplify it

[tex]x^2-6x=-3[/tex]

step-3:

Add both sides 3^2

[tex]x^2-6x+3^2=-3+3^2[/tex]

now, we can complete square

[tex](x-3)^2=6[/tex]

step-4:

Take sqrt both sides

[tex](x-3)=-\sqrt{6},(x-3)=\sqrt{6}[/tex]

step-5:

Add both sides by 3

we get

Step-by-step explanation:

we are given system of equations as

[tex]84x+12y=9612[/tex]

[tex]126x+21y=13643[/tex]

We can simplify each system of equations

[tex]84x+12y=9612[/tex]

we can factor out common terms

[tex]12\times 7x+12\times y=12\times 801[/tex]

[tex]12(7x+y)=12\times 801[/tex]

we can divide both sides by 12

[tex]7x+y=801[/tex]

now, we can simplify second system of equation

[tex]126x+21y=13643[/tex]

Firstly, we can factor

[tex]7\times 18x+7\times 3y=7\times1949[/tex]

[tex]7(18x+3y)=7\times1949[/tex]

we can divide both sides by 7

[tex]18x+3y=1949[/tex]

so, we get

A: [tex]7x+y=801[/tex]

B: [tex]18x+3y=1949[/tex]

Answer:

The answer is A

Step-by-step explanation:

5x + 18 = 7x - 12

Subtract 7x from both sides

5x + 18 - 7x = 7x - 12 - 7x

-2x + 18 = -12

Subtract 18 from both sides

-2x + 18 - 18 = -12 - 18

-2x = -30

Divide both sides by -2

-2x/-2 = -30/-2

x = 15

Solution to system is

x = 6 and y= 4

S.set={6,4}

Step-by-step explanation:

The given equations are

x + 3y = 18                      ................(i)

x + 2y=14                        .................(ii)

Subtracting both equation

(x+3y)-(x+2y)=18-14

x+3y-x-2y = 4

y = 4

put the value of y in equation (i)

the equation becomes

x + 3(4) = 18

x + 12 = 18

subtracting 12 from both sides

x + 12 -12 = 18-12

x =6

Solution to system is

x = 6 and y= 4

75000/1000 = 75

75 x $3.83 = $286.50 AP

The premium for a 10-year, $75000 life insurance policy for a healthy 30-year-old male typically ranges from $10 to $20 per month. Actual pricing can vary based on health status, lifestyle, occupation and the specific insurance company's underwriting process. To get the most accurate premium, it's beneficial to shop around and compare quotes.

The premium for a life insurance policy varies based on several factors including the age of the individual, the amount of coverage, policy term, and the individual's health status. The question doesn't provide enough information for an exact calculation as we do not know the general health status of the 30-year-old male, his occupation, lifestyle factors or the premium rates of the specific insurance company. However, we can give a general idea.

Assuming this individual is in good health, for a 30-year-old male, a $75000, 10-year term life insurance policy would typically cost between $10 to $20 per month. This is an average and the actual cost can vary greatly based on the factors mentioned.

Also, each insurance company has different pricing and underwriting processes, so it's important to shop around and compare quotes from different companies to ensure you're getting the best rate.

Example with temperature:

The temperature -3 degrees is warmer than -5 degrees. This applies to celsius or fahrenheit. You might also write "negative 3 degrees" as "3 degrees below zero"; the same applies for -5. The absolute difference between the two temperatures is 2 degrees.

=================================================

Example with money:

If your bank balance is -3 dollars and your friend's bank balance is -5 dollars, then your friend owes more money to the bank (s/he owes $2 more than you do).

Negative balances mean you are in debt. Another way to look at this is to consider you want to buy an item worth $10 but you only have $7. If the store owner lends you the difference, which you pay back later, then 7-10 = -3 is the amount of money on your balance sheet indicating you are in debt $3. The order of subtraction is important. Saying 10-7 = 3 shows a positive bank balance and you wouldn't be in debt (and still have $3 in your pocket).

=================================================

In either example, the value -3 is to the right of -5 on the number line so we would write the inequality -3 > -5 to say that -3 is larger than -5. Have a look at the image attached below.

Answer:

Step-by-step explanation:

So it's easier if we can write it first in mixed fractions. 9 x 8 is 72 and th is the highest we can go. So it becomes [tex]8\frac{4}{9}[/tex]. Then, if you just long divide 4 by 9 you get .44444.... So it is 8.4 repeating.

8.444 decimal is equivalent to fraction 76/9.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given a fraction of 76/9

Simplifying the above fraction,

this is a standard right triangle 30-60-90

with legs 1 and [tex]\sqrt{3}[/tex] and hypotenuse 2, hence

s = [tex]\sqrt{3}[/tex] and h = 2

Answer:

A. [tex]\sqrt{3}[/tex] ; 2

Step-by-step explanation:

Since We have all the angles of the triangle and one side we can use SIN, COS, and TAN to find the missing side lengths. SIN which is [tex]sin(x) = \frac{opposite}{hypotenuse}[/tex] can be used to find the hypotenuse

[tex]sin(30) = \frac{1}{h}[/tex]

[tex]\frac{1}{sin(30)} = \frac{h}{1}[/tex] ..... inverse both sides

[tex]\frac{1}{sin(30)} = h[/tex]

[tex]2 = h[/tex]

Now we can use the Pythagorean theorem to find the missing length. The Pythagorean Theorem is [tex]a^{2} +s^{2} = h^{2}[/tex]. So we just plug in the values we already have and solve for s.

[tex]1^{2} +x^{2} = 2^{2}[/tex]

[tex]1+s^{2} = 4[/tex]

[tex]s^{2} = 3[/tex]

[tex]s = \sqrt{3}[/tex]

In Conclusion, s = [tex]\sqrt{3}[/tex] and h = 2

Answer: [tex]50^{\circ}[/tex]

Step-by-step explanation:

By the definition  of quadrilateral,

A quadrilateral has four interior angles and the sum of all interior angle of a quadrilateral is always equal to [tex]360^{\circ}[/tex]

Here the measurements of three interior angles are [tex]85^{\circ}[/tex], [tex]105^{\circ}[/tex] and [tex]120^{\circ}[/tex]

Let the measurement of fourth angle is x degree.

Thus,  [tex]85^{\circ}+105^{\circ}+120^{\circ}+x=360^{\circ}[/tex]

[tex]310^{\circ}+x=360^{\circ}[/tex]

[tex]x = 360^{\circ}-310^{\circ}=50^{\circ}[/tex]

Thus, the measure of fourth angle is [tex]50^{\circ}[/tex]

The measure of the 4th angle is 50 degrees.

To find the measure of the fourth angle of a quadrilateral, we need to know that the sum of all the interior angles of a quadrilateral is always 360 degrees. Therefore, to find the measure of the fourth angle, we can subtract the sum of the other three angles from 360. In this case, the given angles are 85, 105, and 120 degrees, so the sum of these three angles is 85 + 105 + 120 = 310 degrees. To find the measure of the fourth angle, we subtract 310 from 360: 360 - 310 = 50 degrees.

Answer:

0.25 in²

Step-by-step explanation:

This is all basic stuff of conversion and multiplication

Option D, The area of the rectangle is 6/24 square inches.

The area of a rectangle is calculated by multiplying its length and width. Given a rectangle with a length of 3/8 inch and a width of 2/3 inch, we can find the area using the formula:

Area = Length × Width

Substitute the given values:

Area = (3/8) × (2/3)

To multiply these fractions, multiply their numerators and their denominators:

Area = (3 × 2) / (8 × 3) = 6 / 24

After simplifying the fraction 6/24, we get 1/4.

Therefore, the area of the rectangle is 1/4 square inches. Among the answer choices, Option D (6/24) is equivalent to 1/4, so the correct answer is Option D.
