Algebra-Which factor makes these equations correct?? 6xk=54 Kx9=81

Answer:

Step-by-step explanation:

Answer: 98 cm²

Step-by-step explanation:

When a cartographer enlarges a map with a scale factor, both the length and the width are multiplied by the scale factor. In this case, the scale factor is 3.5.

Original dimensions of Colorado on the map:

Length: 4 cm

Width: 2 cm

Enlarged dimensions using the scale factor of 3.5:

Length: 4 cm × 3.5 = 14 cm

Width: 2 cm × 3.5 = 7 cm

To find the area of the enlarged map, multiply the enlarged length and width:

Area = Length × Width

Area = 14 cm × 7 cm

Area = 98 cm²

The area of the enlarged map is 98 cm².

Answer:

[tex](3x, 3y)[/tex]

Step-by-step explanation:

The scale factor is 3 so you multiply 3 by the (x,y) to get (3x,3y) as the scale factor

The BMI​ of a person whose weight is 176 lb and whose height is 77 inches is 21.

First, let's use the given information to find the constant of proportionality in the BMI formula:

BMI = k × (weight in pounds) / (height in inches)²

When the 6-foot-tall person weighing 177 lb has a BMI of 24, we can plug in the values and solve for k:

24 = k ₓ 177 / (72²)

k = 24 ₓ (72²) / 177

k ≈ 9.94

Now we can use this value of k to find the BMI of the person whose weight is 176 lb and whose height is 77 in:

BMI ≈ 21

BMI = 9.94 ₓ 176 / (77²)

Therefore, the BMI (to the nearest whole number) of the person is 21, which falls within the healthy weight range of 19 to 25.

Answer: 6.3 per bag

Step-by-step explanation:

31.50 divided by 5 is 6.3!!!!

Answer: 6.3

Step-by-step explanation:

Divide 31.50 with 5

[tex]5\sqrt{31.50}[/tex]

5 goes into 3 0 times so you do 31/5. You get 6 with 1 as the remainder since 6x5 is 30. Now you do 15/5 which is 3. You get 63 but you have to add the decimal between the 6 and 3 so you will get 6.3. Hope this helped.

Answer:

[tex]f(x)=-3x^2+5[/tex]

[tex]f(2) = -7[/tex]

Step-by-step explanation:

Given equation:

[tex]y+3x^2=5[/tex]

To solve the equation for y in terms of x, simply subtract 3x² from both sides of the equation:

[tex]\implies y+3x^2-3x^2=5-3x^2[/tex]

[tex]\implies y=-3x^2+5[/tex]

Replace y with the function notation f(x):

[tex]f(x)=-3x^2+5[/tex]

Finally, to find the value of f(2), substitute x = 2 into the function:

[tex]\begin{aligned}\implies f(2)&=-3(2)^2+5\\&=-3(4)+5\\&=-12+5\\&=-7\end{aligned}[/tex]

Answer:

Step-by-step explanation:

To find:-

Answer:-

We are here a given a equation, with some steps to follow, in order to find out the value of [tex]f(2)[/tex].

Step 1 :- Solve the equation in terms of y ,

The given equation to us is,

[tex]\longrightarrow y + 3x^2 = 5\\[/tex]

To solve for y , we need to transpose 3x² from LHS to RHS , by doing this , the sign changes from positive to neagative .

[tex]\longrightarrow y = 5 - 3x^2 \\[/tex]

Step 2 :- Replace y with function notation [tex]f(x)[/tex]

Just simply replace y here with f(x) as ,

[tex]\longrightarrow f(x) = 5 - 3x^2\\[/tex]

Step 3 :- Find f(2) .

To calculate the value of f(2) , we need to put x = 2 , in the above equation as ,

[tex]\longrightarrow f(2) = 5 - 3(2)^2\\[/tex]

Simplify,

[tex]\longrightarrow f(2) = 5 - 3(4)\\[/tex]

[tex]\longrightarrow f(2) = 5 - 12\\[/tex]

[tex]\longrightarrow \boxed{ \boldsymbol{f(2) = -7 }} \\[/tex]

Hence the required answer is -7 .

5)  ∠1 and ∠3

6)  x = 10

Step-by-step explanation:

Adjacent angles are two angles that share a common vertex and a common side, but do not overlap.

Therefore, the pairs of adjacent angles in the given diagram are:

Vertical angles are pairs of non-adjacent angles that are formed when two lines intersect.  Vertical angles are congruent,

Therefore, the pair of vertical angles in the given diagram are:

As ∠1 and ∠3 are the same measure:

⇒ m∠1 = m∠3

⇒ (9x)° = 90°

⇒ 9x = 90

⇒ 9x ÷ 9 = 90 ÷ 9

⇒ x = 10

Therefore, the value of x is 10.

The monthly interest yield on Tom's retirement account for a 30-year period would be $637.71.

Assuming that the interest is compounded monthly, the monthly yield on Tom's retirement account with an APR of 4.57% for a 30-year period can be calculated using the formula:

Monthly Yield = (Principal × Monthly Interest Rate) ÷ (1 - (1 + Monthly Interest Rate[tex])^{(-Number of Months)}[/tex]

Here, Principal = $160,000

APR = 4.57%,

Number of Months = 30 years ÷ 12 months/year = 360 months.

First, we need to convert the APR to a monthly interest rate by dividing it by 12:

Monthly Interest Rate = 4.57% × 12

Monthly Interest Rate = 0.3808%

Monthly Yield = (160000 × 0.3808%) ÷ (1 - (1 + 0.3808%[tex])^{-360}[/tex]

Monthly Yield = $637.71

Perimeter: 60.8

Area: 64.2

In mathematics, the two key characteristics of two-dimensional forms are area and perimeter. The difference between area and perimeter is how much room each type of shape takes up.

Mathematical concepts like area and perimeter are crucial because they are applied to daily living. Any size and form, whether regular or irregular, can use this. Each design has a unique area and perimeter calculation. Forms like triangles, squares, rectangles, circles, spheres, etc. should be known to you. Here, the boundaries and surfaces of all forms are explained.

The required size and perimeter of the Area are respectively 27.42 and 64.26 square units.

A shape's perimeter is its circumference. How are perimeters determined? By adding the lengths of each side of a shape, the border may be obtained.

A shape comprised of two circles and a rectangle has been provided.

the size of a circle = 12 - 6 = 6

then radius = 3 units

Perimeter = 3+3+3+3+3+3+π(3)

= 18 + 3.14(3)

= 18 + 9.42

= 27.42 units

and

Area = area of rectangle + area of two half circles

= 12(3) + π(3)²

= 36 + 28.26

= 64.26 sq units.

Therefore, the shape's needed area and perimeter are respectively 27.42 and 64.26 square units.

[tex] \angle3 \: and \: \angle4 [/tex] are complementary.

What is Complementary angle?

If sum of two angles is 90° then we can say that those angles are complementary.

For example, if [tex] \angle \: a + \angle \: b = {90}^{o} [/tex] then angle a and angle b are complementary.

Here are some examples of complementary angles:

Here given,

[tex] \angle1 \: and \angle2[/tex] are complimentary.

So,

[tex] \angle1 + \angle2 = {90}^{o} [/tex]

It is clear that [tex] \angle1, \angle2, \angle3, \angle4[/tex] are making a straight angle.

So, we can write,

[tex] \angle1 + \angle2 + \angle3 + \angle4 = {180}^{o} \\ {90}^{o} + \angle3 + \angle4 = {180}^{o} \\ \angle3 + \angle4 = {180}^{o} - {90}^{o} \\ \angle3 + \angle4 = {90}^{o} [/tex]

One incident that shows how selection works in the process of perception is when you are at a party and you hear your name being mentioned in a conversation across the room. In this situation, your attention is immediately drawn to the conversation, and you focus on it while filtering out other sounds and distractions around you.

This is an example of selective attention, where you choose to focus on a particular stimulus and ignore others.

Using factors, we can conclude that the new product will be 48 time more than the old product.

In mathematics, the factor of a number is a divisor of the inputted integer that entirely divides it, leaving no residue. We can use a variety of techniques, including the division method and the multiplication method, to identify a number's components.

Let the product be P.

Let the numbers be a and b.

Now,

P = a × b

According to the question.

Let a is increased by a factor of 12 and b by 4:

P = 12a × 4b

P = 48 × a × b

Hence, we can conclude that the product will increase by a factor of 48.

Answer:

we need to add the money Andy earned to the negative balance he had. So, we have:

-$45 + $30 + $25 = $10

Therefore, Andy now has $10 in his checking account.

Answer:

Andy now has $10 in his checking account.

Step-by-step explanation:

Andy starts the week with -$45 in his checking account. When he gets paid $30 for mowing the grass and $25 for vacuuming the house, his total earnings for the week are:

$30 + $25 = $55

To find out how much money he now has in his checking account, we need to add his earnings to his starting balance of -$45. Adding a negative number is the same as subtracting a positive number, so we can write this as:

-$45 + $55 = $10

Therefore, Andy now has $10 in his checking account.

The tax rate of a house valued at $115,000 with a property tax of $1265 is 110%. or $110 per $1,000 of property value.

The property tax is the levy imposed on the assessed value of the property of an individual or corporation.

Property tax is usually levied as a percentage of the assessed value.

Property tax = $1265

House value - $115,000

Tax rate = 110% [tex](\$1265\div\$115000 \times 100)[/tex]
