Answer:

y=7(3)= 21

y=7(8)= 56

y=7(10)= 70

Step-by-step explanation:

Answer:

X     Y

3     21

8     56

10    70

Step-by-step explanation:

Find Y by plugging in each X value to the given function.

Encuentre Y reemplazando cada valor de X en la función dada.

When x = 3 : y = 7 * 3 = 21

Cuando x = 3 : y = 7 * 3 = 21

When x = 8 : y = 7 * 8 = 56

Cuando x = 8 : y = 7 * 8 = 56

When x = 10 : y = 7 * 10 = 70

Cuando x = 10 : y = 7 * 10 = 70

Answer:

6 inches

Step-by-step explanation:

If the perimeter of the whole pentagonal sign is 30 inches, each side must be 6 inches. Why? A pentagon has 5 sides, and each side is equivalent. 30/5=6.

The area of the trapezoidal tarp in the hotel is 47.3 square inches

The area of a trapezoid is calculated using:

Area = 0.5 * (Sum of parallel sides) * Height

From the complete question, the parallel sides are:

10 ft and 12 ft

So, we have:

Area = 0.5 * (10 +  12) * h

Evaluate

Area = 11 * h

The height (h) is calculated using the following cosine function

cos(120 - 90) = h/5

This gives

cos(30) = h/5

Make h the subject

h = 5cos(30)

Evaluate

h = 4.3

So, we have:

Area = 11 * 4.3

Evaluate

Area = 47.3

Hence, the area of the trapezoid is 47.3 square inches

Answer: To find the height, first find that <D is 120.

This means the height of the trapezoid is approximately 4.3 feet.

So, the area of the tarp is approximately 47.3 square feet.

Work Shown:

E = exterior angle = 60 degrees

n = number of sides of the regular polygon

n = 360/E

n = 360/60

n = 6

The regular polygon has 6 sides.

Answer:

$20

Step-by-step explanation:

let 1 meter of sulu = s, lusia has m dollar

7s = m + 1 => m = 7s - 1

5s = m - 5

5s = 7s - 1 - 5

2s = 6

s = 3

m = 7s - 1 = 21 - 1 = 20

Answer:

→ 50°

→ Acute triangle

Step-by-step explanation:

the measure of the third angle = 180 - (60 + 70) = 180 - 130 = 50°

definitions=======================================

Acute angle : it’s an angle that measures less than 90°.

Acute triangle: it’s a triangle with three acute angles.

………………………………………………………………………………………………

The measures of the angles in our triangle are respectively 60° , 70° , 50°

Thus ,it’s an acute triangle .

Remark

There are 6 faces on a cube.

Each face has an area of s^2

s = 5

One face is s^2

One face is 5^2 = 25 cm^2

6 faces are 6*25 cm^2

6 faces are 150 cm^2

Answer:

Well for 1 question it would be a 25% chance but since its two i would say its a 50% chance

Step-by-step explanation:

Answer:

See below ~

Step-by-step explanation:

Question 1

⇒ -7x - (8x + 16) = -1

⇒ -7x - 8x - 16 = -1

⇒ -15x = 15

⇒ x = -1

⇒ y = 8(-1) + 16 = 8

⇒ Solution = (-1, 8)

Question 2

⇒ 3x + 4(-3x - 18) = 0

⇒ 3x - 12x - 72 = 0

⇒ -9x = 72

⇒ x = -8

⇒ y = -3(-8) - 18 = 6

⇒ Solution = (-8, 6)

Question 3 (not clear)

Question 4

⇒ -8x - 7(6x) = 0

⇒ -8x - 42x = 0

⇒ -50x = 0

⇒ x = 0

⇒ y = 6(0) = 0

⇒ Solution = (0, 0)

Question 8

⇒ 2x - 6(-5x - 19) = -14

⇒ 2x + 30x + 114 = -14

⇒ 32x = -128

⇒ x = -4

⇒ y = -5(-4) - 19 = 1

⇒ Solution = (-4, 1)

The values of n and p which makes the system of equations true are 10 and 20 respectively.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have system of equation:

p=2n  and

p−5=1.5n

Put p = 2n in the other equation.

2n - 5 = 1.5n

2n = 1.5n +5    (add 5 on both sides)

0.5n = 5           (subtract 1.5n on both sides)

n = 10              (divide by 0.5 on both sides)

Put n = 10 in the equation p = 2n

p = 2(10) = 20

Thus, the values of n and p which makes the system of equations true are 10 and 20 respectively.

Answer:

y ≈ 46.2

Step-by-step explanation:

using the law of sines , then

[tex]\frac{y}{sin85}[/tex] = [tex]\frac{31}{sin42}[/tex] ( cross- multiply )

y × sin42° = 31 × sin85° ( divide both sides by sin42° )

y = [tex]\frac{31sin85}{sin42}[/tex] ≈ 46.2 ( to the nearest tenth )

(answer is above)

Step-by-step explanation:

s = top speed

p = horsepower

s = 27.3 × p^(1/6)

the exponent 1/6 means the 6th root of p.

17.

s = 27.3 × 70^(1/6) = 27.3 × 2.030094899... =

= 55.42159075... knots

18.

50 = 27.3 × p^(1/6)

50⁶ = 27.3⁶ × p

p = 50⁶/27.3⁶ = (50/27.3)⁶ = (1.831501832...)⁶ =

= 37.74367151... horsepower
