Answer:

Step-by-step explanation:

3/4(x-12)=12

3/4x - 3/4(12) = 12

3/4x - 9 = 12

3/4x = 12 + 9

3/4x = 21

1/4x = 7

x = 28

3/4y - 12=12

3/4y = 12 + 12

3/4y = 24

1/4y = 8

y = 32

Answer:

1 3/15

Step-by-step explanation:

Take 18 divided by 15, make it a fraction which is 18/15 then divide (how many 15's go into 18?) since 1 15 goes into 18 you put a 1 in the whole number place, and the remainder is 3/15.

Answer:

D

Step-by-step explanation:

B is not correct.

Convention says that the number after the divide sign must be in the denominator. In plain English, that means you must have 18 on the top and 15 on the bottom like this

18

===

15

Since that is not one of your answers you have to break it down

18 can be divided by 15 once.  That means that  A is not right either.

So all you have left is C and D

There's 3 left over when you divide 18 by 15.

Only one answer is possible

58×13=696!!!!!!!!!!!!!!!!!!!!

Answer:

[tex]58\times 12=696[/tex]

Step-by-step explanation:

We have to multiply 58 and 12.

This could be done by distributive property of multiplication over addition which is:

[tex]a\times b\\=a\times (c+d)\\=(a\times c) + (a\times d)[/tex]

Evaluation of [tex]58\times 12[/tex]

[tex]58\times 12\\=58\times (10 + 2)\\=(58\times 10) + (58\times 2)\\=580 + 116\\=696[/tex]

Distributive property makes us easy to calculate complicated product by dividing the number into smaller parts.

Answer:it is 13.45

Step-by-step explanation:

The largest value among the provided numbers is 13.5. In decimal numbers, the higher the value after the decimal point, the larger the fraction of a whole number it represents. Therefore, 13.5, with '.5' after the decimal point, represents the largest value.

In order to find the largest value among the given numbers, it will be useful to first understand how decimal numbers work. Decimal numbers are a method of writing fractions in a way that is easier to work with. In a decimal number, the number after the decimal point represents a fraction of a whole number. The larger this number, the larger the fraction of the whole number it represents.

In your list, you have five numbers: 13.05, 13.5, 13.06, 13.45, and 13.07. If we compare just the numbers after the decimal point, we'll see that '.5' is the largest. Therefore, 13.5 is the largest number among your list.

When a square with 15 cm sides is enlarged by a ratio of 3:4, the resulting square has a side length of 20 cm, and consequently, an area of 400 cm².

If a square with sides of 15 cm is enlarged in a ratio of 3:4, we first need to determine the new length for the sides of the resulting square. To do this, we take the original side length (15 cm) and multiply it by the scale ratio.

The scale ratio is 3:4 which means for every 3 units of the original, the new square will have 4 units. Therefore, we calculate the new side length as follows:

Now, to find the area of the resulting square, we square the new side length:

Area = side × side = 20 cm × 20 cm = 400 cm²

So, the area of the resulting square is 400 cm².

Option 3. (23, 14)

Step-by-step explanation:

B is correct. 7*-1= -7. -2*1=-2 -7+2= -5

Answer:

The correct answer is D because both ordered pair when substituted to the equation, both sides of the equation didn't equal to each other.

Explanation:

All you do is substitute. (x,y)

A:

Substitute

7(1) - 2(5) = -5

Multiply the number inside the parentheses by the number outside.

7 - 10 = -5

Subtract the numbers.

-3 = -5

This is not the solution to the equation because the numbers on both sides don't equal to each other.

B:

Substitute

7(-1) - 2(1) = -5

Multiply the number inside the parentheses by the number outside.

-7 - 2 = -5

Subtract the numbers.

-9 = -5

This also not the solution to the equation because the numbers on both sides don't equal to each other.

C:

They both are not the solution to the equation because the numbers on both sides don't equal.

2a + 3 Remainder 6

Step-by-step explanation:

Find the attachment bellow for a step by step explanation.

Answer:

2a + 3

Step-by-step explanation:

We are given the following two terms and we are to divide them:

[tex] \frac { 2 a ^ 2 + a + 3 } { a - 1 } [/tex]

We will start by divide the highest order term in the dividend  [tex]2a^2[/tex] by the highest order term in divisor  [tex]a[/tex]:

[tex]\frac{2a^2 + a + 3}{a-1}=2a[/tex]

Then we multiply the new quotient term by the divisor where [tex]-2a^2+2a[/tex] is subtracted by [tex]2a^2+a[/tex].

After changing the signs, add the last dividend from the multiplied polynomial to find the new dividend to get:

[tex]2a+3[/tex] as the quotient and [tex]6[/tex] as the remainder.

Answer: x  /  y

              0  /  4

Step-by-step explanation:

Answer:

x          y

0          4

20       0

-10       6

Step-by-step explanation:

x + 5y = 20

5y = -x + 20

 y = -1/5 x + 4

so

when x = 0,

y = -1/5 (0) + 4

y = 4

when y = 0 then

0 = -1/5 x + 4

-4 = -1/5 x

x = (-4) (-5)

x = 20

when y = 6 then

6 = -1/5 x + 4

2 = -1/5 x

x = 2 * (-5)

x = -10

Answer:

1/25

Step-by-step explanation:

Total number of DVD's in the box = 20

Number of defective DVD's = 4

The probability of picking up a defective DVD = [tex]\frac{4}{20}=\frac{1}{5}[/tex]

This DVD is being replaced back. So this does not change the total number of DVD's in the box and the number of defective DVD's in the box.

So again the probability of picking up the second defective DVD = [tex]\frac{4}{20}=\frac{1}{5}[/tex]

The probability that both DVD's are defective will be the product of probabilities of individual events i.e.

[tex]\frac{1}{5} \times \frac{1}{5}  = \frac{1}{25}[/tex]

Thus, the probability that both DVDs are defective is 1/25

The probability of selecting two defective DVDs from a box containing 20 DVDs with 4 defective ones, with replacement, is 1/25.

To find the probability that both DVDs are defective, we need to consider the probability of selecting a defective DVD on each trial.

Since the DVDs are selected with replacement, the probability remains constant.

There are 20 DVDs in total, with 4 of them being defective.

So the probability of selecting a defective DVD on the first trial is 4/20 = 1/5.

Similarly, the probability of selecting a defective DVD on the second trial is also 1/5.

To find the probability that both DVDs are defective, we multiply these probabilities together:

Probability = (1/5) * (1/5) = 1/25

Final answer:

The interest rate charged by the credit card company for a $90 purchase with an $18 interest charge is calculated to be 20%.

Explanation:

To calculate the interest rate charged by the credit card company on a $90 purchase with an $18 interest charge, we need to use the formula for interest rate:

Interest Rate = (Interest / Principal) × 100

Applying the given values:

Interest Rate = ($18 / $90) × 100

Interest Rate = 0.2 × 100

Interest Rate = 20%

The interest rate the credit card company charged on the purchase is 20%.

Answer:

theyre both the same rate.

The slope is 3/2

Step-by-step explanation:

Slope is calculated by rise over run so there are three points for you. You start from a point that hits the line then you go up 3 units and across 2 units and you hit the next point. That means the slope is 3/2

Hope this helps and I tried my best on explaining it's hard without being able to show it to you!

Answer:

The slope of given line = 2/3

Step-by-step explanation:

Let (x₁, y₁) and (x₂, y₂) be the two points on a line, the slope of the line is given by,

Slope = (y₂ - y₁)/(x₂ - x₁)

Form the figure we get some coordinates points

(2, 3),  (4,6) , (6, 9)

To find the slope of  line

Consider two points

(x₁, y₁)  = (2, 3) and  (x₂, y₂) = (4, 6)

Slope = (y₂ - y₁)/(x₂ - x₁) = (4 - 2)/(6 - 3) = 2/3

Therefore the slope of given line = 2/3

Explaining the volume of a sphere with a radius of 6 feet using the formula V = (4/3)πr³.

The volume of a sphere with a radius of 6 feet can be calculated using the formula:

V = (4/3)πr³

Given r = 6 feet, substituting the value, we get:

V = (4/3)π(6)³ = (4/3)π(216) = 288π cubic feet

Answer:

[tex]\$7,770.81[/tex]  

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to  

[tex]V=P(1-r)^{x}[/tex]  

where  

V is the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal  

x  is Number of Time Periods  

in this problem we have  

[tex]P=\$8,599\\r=2.5\%=0.025\\x=4\ years[/tex]

substitute

[tex]V=\$8,599(1-0.025)^{4}=\$7,770.81[/tex]  

Final answer:

After 4 years, Mariah's car will depreciate to approximately $7,761.66, following a 2.5% annual depreciation rate.

Explanation:

To calculate the depreciated value of a car, we can use the formula for exponential decay, which is:

V = P[tex](1 - r)^t[/tex]

where V is the final value of the car after time t, P is the initial purchase price of the car, r is the rate of depreciation per year, and t is the number of years.

For Mariah's car, the initial purchase price (P) is $8,599, the rate of depreciation (r) is 2.5%, or 0.025 when expressed as a decimal, and the time period in question (t) is 4 years.

Now we can perform the calculation:

V = $8,599[tex](1 - 0.025)^4[/tex]
V = $8,599[tex](0.975)^4[/tex]
V = $8,599(0.9025)
V ≈ $7,761.66

So, after 4 years, the value of the car will approximately be $7,761.66, when rounded to the nearest hundredth.

Answer:

Surface Area = 471.2 cm^2

Surface Area = 60.75 m^2

Step-by-step explanation:

The surface area formula for a cylinder is π x diameter x (diameter / 2 + height), where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is π x radius x 2 x (radius + height). ( π =3.14 )

FORMULA:

π x 5 x 2 x 15

WORK:

π x 5 = 15.7

15.7 x 2 = 31.4

31.4 x 15 = 471

The surface area formula for a triangular prism is 2 * (height x base / 2) + length x width1 + length x width2 + length x base.

FORMULA:

2 x (2.5 x 1.5/2) + (6 x 4) + (6 x 4) + (6 x 1.5)

WORK:

(2.5 x 1.5) = 3.75/2 = 1.875

1.875 x 2 = 3.75

(6 x 4) = 24

(6 x 4) = 24

(6 x 1.5) = 9

3.75 + 24 + 24 + 9 = 60.75
