The cost to rent a rug-cleaning machine from the supermarket is $23 per day. The supermarket charges a check-out fee of $45 for the rental. Tristanne spent $137 to rent the rug-cleaning machine. If d represents the number of days Tristanne rents the machine, which equation can be used to find the value of d?
23 d = 137
23 d + 45 = 137
45 d = 137
45 d + 23 = 137

In a triangle, The value of x is, 40°

And, The value of y is, 50°

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

The triangle is show in figure.

We know that;

In a triangle, the pair of two opposite sides are equal then there corresponding angles are also equal.

Now, By figure we can formulate;

⇒ x + x + 100 = 180

Solve for x;

⇒ 2x + 100 = 180

⇒ 2x = 180 - 100

⇒ 2x = 80

⇒ x = 40

Thus, The value of x = 40°

And, We get;

⇒ x° + y° + 90° = 180°

⇒ 40 + y + 90 = 180

⇒ y + 130 = 180

⇒ y = 180 - 130

⇒ y = 50°

Thus, The value of y = 50°

Step-by-step explanation:

Answer:

It's 16 yards.

Step-by-step explanation:

20 - 16.16 = $3.84

3.84 = 384 cents

384 : 24 = 16

Kira bought 16 yards of the ribbon, as of the given conditions.

As mentioned in the question, Kira got a prepaid debit card with $20 on it. The price of the ribbon was 24 cents per yard. If after that purchase there was $16.16 left on the card,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Kira got a prepaid debit card with $20 on it.
After that purchase, there was $16.16 left on the card,
Cost of the ribbon purchased = 20 - 16.16
The cost of the ribbon purchased = $3.84

The price of the ribbon was 24 cents per yard.,
Now yard of ribbon Kira purchased = 3.84 / 0.24 = 16 yards

Thus, Kira bought 16 yards of the ribbon, as of the given conditions.

Answer:

A, B, D, E

Step-by-step explanation:

Given expression:

When multiplying decimals, multiply as if there are no decimal points:

\(\implies 6 \times 154 = 924\)

Count the number of digits after the decimal in each factor:

Therefore, there is a total of 5 digits.

Put the same number of total digits after the decimal point in the product:

\(\implies (0.06) \cdot (0.154)=0.00924\)

-----------------------------------------------------------------------------------------------

Answer option A

\(\boxed{6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}}\)

When dividing by multiples of 10 (e.g. 10, 100, 1000 etc.), move the decimal point to the left the same number of places as the number of zeros.

Therefore:

\(\implies 6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}=(0.06) \cdot (0.154)\)

Therefore, this is a valid answer option.

Answer option B

\(\boxed{6 \cdot 154 \cdot \dfrac{1}{100000}}\)

Multiply the numbers 6 and 154:

\(\implies 6 \times 154 = 924\)

Divide by 100,000 by moving the decimal point to the left 5 places (since 100,000 has 5 zeros).

\(\implies 6 \cdot 154 \cdot \dfrac{1}{100000}=0.00924\)

Therefore, this is a valid answer option.

Answer option C

\(\boxed{6 \cdot (0.1) \cdot 154 \cdot (0.01)}\)

Again, employ the technique of multiplying decimals by first multiplying the numbers 6 and 154:

\(\implies 6 \cdot 154 = 924\)

Count the number of digits after the decimal in each factor:

Therefore, there is a total of 3 digits.

Put the same number of digits after the decimal point in the product:

\(\implies 0.924\)

Therefore, as (0.06) · (0.154) = 0.00924, this answer option does not equal the given expression.

Answer option D

\(\boxed{6 \cdot 154 \cdot (0.00001)}\)

Again, employing the technique of multiplying decimals.

As there are a total of 5 digits after the decimals:

\(\implies 6 \cdot 154 \cdot (0.00001)=0.00924\)

Therefore, this is a valid answer option.

Answer option E

\(\boxed{0.00924}\)

As we have already calculated, (0.06) · (0.154) = 0.00924.

Therefore, this is a valid answer option.

Answer:

∠ T = 126°

Step-by-step explanation:

in an isosceles trapezoid

• lower base angles are congruent

• any lower base angle is supplementary to any upper base angle

then

∠ U = ∠ W = 54° , so

∠ T + ∠ U = 180°

∠ T + 54° = 180° ( subtract 54° from both sides )

∠ T = 126°

The 7th term in the sequence is 128.

How to find nth term in the sequence?

To find a specific term in a sequence, you need to know either the formula for the nth term or the values of some of the terms in the sequence. If you know the formula for the nth term, you can substitute the value of n to find the corresponding term.

To find the 7th term in the sequence -1, 2, -4, 8, ......., we need to first identify the pattern in the sequence.

We can see that each term is obtained by multiplying the previous term by -2.

So, the first term is -1, the second term is (-1) x (-2) = 2, the third term is 2 x (-2) = -4, the fourth term is -4 x (-2) = 8, and so on.

Using this pattern, we can find the 7th term as follows:

5th term = 32

6th term = -64

7th term = (-64) x (-2) = 128

Therefore, the 7th term in the sequence is 128.

Answer:

3)

Step-by-step explanation:

An equation is linear if equal changes in x produce equal changes in y.

Let's look at each choice.

1)

A decrease of 10% per year. That means each year, the value of the car is 0.9 times the value of the previous year.

For example, if the original value was $10,000, after 1 year, it is worth 0.9 * $10,000 = $9,000. In 1 year it lost $1,000. In the next year, its value is now 0.9 * $9,000. The value at the end of the 2nd year is $8,100. In the second year, it lost $900 in value. In one period of 1 year it lost $1000 in value. In another equal period of 1 year, it lost $900 in value. A change of 1 year in time produces different changes in loss of value, so it is not linear.

2)

Here, the number doubles every year. Let's say it starts with 100 fish. After 5 years, it has 200 fish. In a change of 5 years in x, the change in y is 100. In the next 5 years, it goes from 200 fish to 400 fish. The change in the second period of 5 years is 200. We see that a change of 5 years can produce a change of 100 fish, but another change of 5 years can produce a change is 100 fish. Since for equal changes in x, the changes in y are not all equal, this is not linear.

3)

Here for every change of 1 day in x, the change in y is 2 liters. Each change of 1 in x always produces a change of 2 in y. This is linear.

4)

Each 2 hours, the amount of caffeine is 2/3 of what it was before. This is similar to the choice 1), and it is not linear.

Answer: 3)

Step-by-step explanation:

Step1

Make y the subject of the formula from equation 2

-15y/-15=-15-15x/-15

Y=15+15/15..............3

Substitute equ..... 3 to equ.... 1

5x-5(15+15/15)=1

5x-1(15+15/3)=1

3*5x-1*3(15+15/3)=1*3

15x-1(15+15)=3

15x-15-15pp=3

15x-30=3

15x=3+30

15x/15=33/15

x=2.2

From equation.....

5x-5y=1

5(2.2)-5y=1

11-5y=1

-5y=1-11

-5y/-5=10/-5

Y=-2

PROVE

FROM EQUATION ONE

5X-5Y=1

5(2.2)-5(-2)=1

11-10=1

1=1

SO Y=-2 AND X=2.2

Answer:

Y = 12.

Explanation: Because 17- 5 is 12 and  when you are doing problems like that, you are supposed to subtract the number behing the equal sign with the number in front of the equal sign. So, that would be 17- 5. And that gives you 12. So, Y=12.

From the question

The opposite is 37

The hypotenuse is 41

So we have

sin ? = 37/41

? = sin-¹ 37/41

? = 64.4805

To find the value of (fg)(1), we need to multiply the values of f(1) and g(1). From the given information, we know that f(1) = 2 and g(1) = -1.

(fg)(1) = f(1) * g(1) = 2 * (-1) = -2.

To find the values of the given expressions, let's break them down step by step:

1. f(a): Since we are given f(1) = 2, we can substitute a = 1 into the function f(a). Therefore, f(1) = 2.

2. f'(b): We are given f'(1) = 6, so we can substitute b = 1 into the derivative of f(x). Therefore, f'(1) = 6.

3. g(1): We are given g(1) = -1.

4. g'(1): We are given g'(1) = -9.

5. (fg)(1): To find the value of (fg)(1), we need to multiply the values of f(1) and g(1). From the given information, we know that f(1) = 2 and g(1) = -1. Therefore, (fg)(1) = f(1) * g(1) = 2 * (-1) = -2.
