Step-by-step explanation:

81 - p

Let p =2

81-2

79

A ratio expresses the number of times one number contains another. The length represented by 1 centimeter in real is 5ft.

A ratio expresses the number of times one number contains another. For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.

Given that a floor plan is drawn using a scale of 3cm/15ft. Therefore, the 3 cm on the floor plan represents 15 ft in real. Thus, we can write the ratio as,

Ratio = Length on floor plan/Length in real = 3cm / 15 ft

Length on floor plan/Length in real = 3cm / 15ft

Now, the length represented by 1 centimeter in real can be written as,

Length on floor plan/Length in real = 3cm / 15ft

1 cm/Length in real = 3cm / 15ft

Length in real = (15ft × 1cm)/3cm

Length in real = 5 ft

Hence, the length represented by 1 centimeter in real is 5ft.

Answer:

[tex]x^2+11x+18[/tex]

[tex](x+9)(x+2)[/tex]

Factoring, if [tex]x^2+11x+18=0[/tex]

The roots/zeros are:

[tex]x=-2,\:x=-9[/tex]

Step-by-step explanation:

Step 1:  Make an equation

[tex]\frac{volume_1}{surface-area_1} = \frac{volume_2}{surface-area_2}[/tex]

[tex]\frac{729}{324} = \frac{512}{x}[/tex]

Step 2:  Cross multiply

[tex]\frac{729}{324} = \frac{512}{x}[/tex]

[tex]729(x) = 324(512)[/tex]

[tex]729x = 165888[/tex]

Step 3:  Divide both sides by 729

[tex]729x / 729 = 165888 / 729[/tex]

[tex]x = \frac{165888} {729}[/tex]

[tex]x = 227.555...[/tex]

Answer: [tex]x = \frac{165888} {729}[/tex] or in decimal form -  [tex]x = 227.555...[/tex]

Answer:

256 m²

Step-by-step explanation:

(Ratio of sides)³ = Ratio of volumes

729/512 = (Ratio of sides)³

Ratio of sides = 9/8

(Ratio of sides)² = ratio of area

(9/8)² = (324/x)

x = 256

Step-by-step explanation:

Answer:

thirty - eight percentage

Step-by-step explanation:

You are going to have to divide for this question.

29.25 / 78 = 0.375

0.375 ≈ 0.38

0.38 * 100 = 38

So 29.25 is 38% of 78.

Answer:

15

Step-by-step explanation:

When two lines intersect the sum of the angles on one side of the line will be equal to 180.  This means that you can add the two values and get 180.

Add the values you have and solve for x.

6x + 3 + 87 = 180

6x + 90 = 180

6x = 90

x = 15

Answer: x = 14

Step-by-step explanation: assuming that (6x + 3) degrees = 87 degrees

6x+3 = 87

6x = 84

x = 14

4500 ≤ 1400 + .05x, where x = sales

800 + .15s = 5000, where s = sales <-- this isn't an inequality, because it's asking for the exact amount of sales Ling needs to get.

(85+76+94+81+y)/5 ≥ 85, where y = next test score

Answer:

5. at least $62,000 worth of cars

6. $28,000 on sales

7. at least an 89

Step-by-step explanation:

5. We have a base salary of $1400 and the earning is 5% on sales (in other words, of the total profits from sales, the salesperson gets 5% of that). If s represents sales, we can say that the salesperson earns:

1400 + 0.05 * s

We want the end product to be at least $4500, so:

1400 + 0.05s ≥ 4500

0.05s ≥ 3100

s ≥ $62,000

The salesperson needs to sell at least $62,000 worth of cars.

6. This is similar to the previous question. Say the number of sales is s. Then, we have:

800 + 15% * s = 5000

800 + 0.15s = 5000

0.15s = 4200

s = 28,000

Ling needs to sell $28,000 on sales.

7. Let's say the last score is x. The average is found by adding all the test scores and dividing by the number of tests:

(85 + 76 + 94 + 81 + x) / 5 ≥ 85

336 + x ≥ 425

x ≥ 89

Latrell needs to earn at least an 89 on his next test to keep his average at 85 or higher.

Answer:

p = (5t)/9

Step-by-step explanation:

9 mins ---------- 5 pages

1 min -------------5/9 page

t mins ------------5/9 x t pages

thus

p = (5t)/9

The linear equation in two variable that represents the number of pages (p) Vicky reads in any given time interval (t) will be;

⇒ p = 5t/9

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

She can read 5 pages in 9 minutes at a constant rate.

Now,

Since, She can read 5 pages in 9 minutes at a constant rate.

Hence, In 9 minutes = 5 pages

So, In 1 minutes = 5/9 pages

Hence, In t minutes, Number of pages = 5t/9

Thus, We can formulate;

The linear equation in two variable that represents the number of pages (p) Vicky reads in any given time interval (t) will be;

⇒ p = 5t/9

Answer:

I agree with Garret.

Step-by-step explanation:

A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.

To get rid of the decimal point in the numerator, we count the numbers after the decimal in 26.6, and multiply the numerator and denominator by 10 if it is 1 number. Therefore, in this case we multiply the numerator and denominator by 10 to get the following fraction:

266 / 10

Then, we need to divide the numerator and denominator by the greatest common divisor(GCD) to simplify the fraction.The GCD of 266 and 10 is 2. When we divide the numerator and denominator by 2, we get the following:

133 / 5, which is ni a p/q form.

The value of a when rewriting (6/17)^9 x as a^x is (6/17)^9.

To find the value of a when we rewrite (6/17)^9 x as a^x, we are looking for a base a that can represent (6/17)^9 raised to the power x. To achieve this, we recognize that (6/17)^9 can be the value of the base a. Therefore, the expression (6/17)^9 x is the same as a^x, where a is equal to (6/17)^9.
