find the volume of the given pyramid. measurements are in feet.


answer:

v = 1/3 bh

the base (b) is a square and the area is20(20) = 400 ft^2

v = 1/3 400(26)

v = 1/3 (400) + 1/3(26) = 142 ft^2

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)

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

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.

Answer:

it would have took 15 years

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 =

Answer:

the answer is -1

Step-by-step explanation:

simple:

7+(-5)

= +2  ( seven has the higher absolute value, so we go with positive)

+2 + (-3)

= -1 (we go with the negative this time because -3 has the higher absolute value)

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:

460 million = 4.6 x 10^8

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

8x + 4 = 28

subtract 4 from both sides

8x + 4 - 4 = 28 - 4

8x = 24

divided both sides by 8

8x / 8 = 24 / 8

x = 3

→ 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 .

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.
