Answer:

El numero es 2

Step-by-step explanation:

Sea x el número.

A partir de la pregunta, la expresión se puede representar matemáticamente como:

[tex]3x ^ 2 = 6x[/tex]

Divide ambos lados de la expresión por x

[tex]\frac{3x ^ 2}{ x} = \frac{6x }{ x}[/tex]

[tex]\frac{3x ^ 2}{ x} = 6[/tex]

[tex]3x = 6[/tex]

Divide ambos lados de la expresión por 3

[tex]\frac{3x}{3} = \frac{6}{3}[/tex]

[tex]x = \frac{6}{3}[/tex]

[tex]x = 2[/tex]

Por tanto, el número es 2

The probability of the next spin landing on a vowel is 2/7.

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, A spinner labeled A, H, B, C, F, D, and E.

We know, The ratio of favorable events to unfavorable events for a given event is known as the odds in favor.

The total number of letters is 7 and the number of vowels is 2.

t = 98 ft

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base.  The height of the tree is equal to 98 feet.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

Using the tangent function of the trigonometry, we can write the ratio of the height to the base will be equal because the angle of sun rays is the same for both.

Height of Tree /Shadow of Tree = Height of the biologist / Shadow of the biologist

Height of the tree/ 28 = 7/2

Height of the tree = (28×7)/2

Height of the tree = 98 feet

Hence, the height of the tree is equal to 98 feet.

Answer:

B.) i think

Step-by-step explanation:

The unknown two numbers are 11 and 3 where the mean of two numbers is 7 and the range of these two numbers is 8.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

The range of a given set of data is defined as the difference between the largest value and the smallest value.

Given that the mean of two numbers is 7 and the range of these two numbers is 8.

Let the pair of number be 11 and 3

11 + 3 = 14

14 / 2 = 7

Mean = 7

Also, the difference between the numbers are;

11 - 3 = 8

Range = 8

Therefore, the unknown two numbers are 11 and 3 where the mean of two numbers is 7 and the range of these two numbers is 8.

Answer:

2/5 yards of fabric

Step-by-step explanation:

A total of 2 yards of fabric is used to make 5 identical pillows. How much fabric is used for each pillow?

5 identical pillows = 2 yards of fabric

1 pillow = x yards

Cross Multiply

x yards × 5 pillows = 2 yards × 1 pillow

x yards = 2 yards × 1 pillow/5 pillows

x yards = 2/5 yards of fabric

Therefore, 2/5 yards of fabric was used for 1 pillow

The corresponding angles of the triangles are equal. Then the triangles ΔFGH and ΔMLN are similar triangles.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

In triangle ΔLMN, the measure of the third angle is calculated as,

∠N + ∠M + ∠L = 180°

∠N + 51° + 36° = 180°

∠N = 93°

In triangle ΔFGH, the measure of the third angle is calculated as,

∠H + ∠F + ∠G = 180°

∠H + 51° + 36° = 180°

∠H = 93°

In triangles ΔFGH and ΔMLN, the corresponding angles are equal. Then the triangles ΔFGH and ΔMLN are similar triangles.

Answer:

The slope is 2

Step-by-step explanation:

To solve for slope, it's: y2-y1/ x2-x1.

The points can be (1,0) and (2,2) since they intersect with the slope.

You plug the points into the equation which is 2-0/ 2-1.

This will give you 2/1 or just 2.

Or you can just do rise over run. The slope is going up by 2 and across by 1.

Answer:

Step-by-step explanation:

5/6 x 18 = 5 x 18/6 = 5x3 = 15

The requried, fraction 5/6 of 18 is equal to 15. In other words, if you take 5/6 of 18, you get 15.

To find 5/6 of 18, we set up the expression as follows:

(5/6) * 18

To multiply a fraction by a whole number, we simply multiply the numerator (the top number) of the fraction by the whole number. The denominator (the bottom number) remains the same. In this case, we have:

(5 * 18) / 6

Now, we multiply the numerator 5 by the whole number 18:

5 * 18 = 90

So, we have:

(90) / 6

Simplify the fraction.

To simplify the fraction, we divide the numerator (90) by the denominator (6):

90 / 6 = 15

Therefore, 5/6 of 18 is equal to 15. In other words, if you take 5/6 of 18, you get 15.

Answer:

The equation of a line in the slope-intercept form is:

y = 5x - 18

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

In our case, we are given

now substituting m = 5 and (4, 2) in the slope-intercept form of the line equation to determine the y-intercept

y = mx + b

2 = 5(4) + b

20 + b = 2

subtract 20 from both side

20 + b - 20 = 2 - 20

b = -18

now substituting b = -18 and m = 5 in the slope-intercept form of the line equation

y = mx + b

y = 5x + (-18)

y = 5x - 18

Therefore, the equation of a line in the slope-intercept form is:

y = 5x - 18

Answer:

y = 45x + 25

Step-by-step explanation:

Slope-intercept equation/form:

y = mx + b

________________________

x is the amount of classes that Toshelle will take and each class costs $45.

So, you multiply them by one another to get:

45x

_________________________

Additionally, there is a one-time payment of $25.

So, you add 25 to the cost to get:

+25

__________________________

y is the total amount of money Toshelle has to pay.

Therefore, you place 45x and +25 into a slope-intecept equation/form to get:

y = 45x + 25
