Step-by-step explanation:

Assuming a number cube is a 6 sided die, half of the numbers are even

65 * 2 = 32.5, which rounds up to 33

Answer:

the answer is the last one.

Step-by-step explanation:

First we multiply both sides of the inequality by -24 to isolate the variable.

Then, since we are multiplying with a negative number, the inequality sign flips.

All we do next is calculate.

Step by step we have

Step-by-step explanation:

If there are 4 parts to the spinner, 4 is the whole. Since there are 2 even numbers (2&4), the fraction would be [tex]\frac{2}{4}[/tex], which is simplified to [tex]\frac{1}{2}[/tex]. And because [tex]\frac{1}{2}[/tex] could also turn into [tex]\frac{50}{100}[/tex], the percentage is 50%.

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

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.

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.

Step-by-step explanation:

Just did it. Got it right

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.

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 roots/zeros are:

31

Step-by-step explanation:

We need to find the value of angle D so that we can solve for X. To do that we need to find the value of angle A and that value will be the same value as D because these angles are the same.

To do that we have to add angles C and B together and that equals 118°. Then we have to realize that all the angles of a triangle add up to 180°. So then we have to subtract 118° from 180° and that equals 62°. So now we have the value of A.

If the value of angle A is 62° then that must be the value of angle D because these two angles are the same. So now that we have the value of angle D we need to solve for X. This equation is asking what times 2 equals the value of X. We know the value of X is 62°. So what times 2 equals 62°?

31×2=62°

Therefore the value of X is 31

Answer:

A, 0.5(x)(x+2)=24, D, x²+2x-48=0, and E, x²+(x+2)²=100

Step-by-step explanation:

A and D are correct because they simply involve the Area of a Triangle formula. A has the formula in the same format, but D has the 0.5 divided from by both sides.

E, on the other hand, uses the Pythagorean theorem to solve for both legs.

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
