A cubic foot holds about 7.5 gallons of water. A ceramic container the shape of a square pyramid has a height of 8 feet. The edges of its base measure 2.7 feet. How many gallons of water will this container hold?

Answer:

Step-by-step explanation:

Answer:

y = -x +2

Step-by-step explanation:

y = mx + b

y=6

x=-4

m=-1 (m is the slope)

b=? (b is the y-intercept)

Putting these numbers into this equation,

6 = -1(-4) + b

b=6-4

b=2

So the equation is y = -1x + 2

or just y = -x +2

8*6-7 =48-7

= 41

18.) 9(3x-4y+8)

27x-36y+72

Answer: Slope:  -1/2     y-intercept:  2

Step-by-step explanation:

Subtract 4 x from both sides of the equation. 8 y = 16 − 4 x Divide each term by 8 and simplify. Divide each term in 8 y = 16 − 4 x by 8 . 8 y 8 = 16 8 + − 4 x 8 Cancel the common factor of 8 . Tap for fewer steps... Cancel the common factor. 8 y 8 = 16 8 + − 4 x 8 Divide y by 1 . y = 16 8 + − 4 x 8. y=2−x2. The slope-intercept form is y = m x + b , where m is the slope and b is the y-intercept. y = m x + b Reorder 2 and − x 2 . y = − x 2 + 2. Rewrite in slope-intercept form. y = − 1 2 x + 2.Slope:−1/2  y-intercept:2

Answer:

b

Answer:

x = 11

Step-by-step explanation:

Remark

There are two legs. They are equal.

Equation

2x - 4 + 2x - 4 +x = 47                   Combine like terms

Solution

5x - 8 = 47

5x - 8+8 = 47 + 8

5x = 55                                           Divide by 5

x = 11

Answer:

The cliff is 335 feet tall.

Step-by-step explanation:

First you convert the angle to degrees and you get 18.683 degrees.

Then you set up the equation where x is the height of the cliff.

Tan(18.683) = (x/991)

Then you solve for x and you get 335 ft when your ound to the nearest whole number.

The cliff is 355 feet high.

Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

We have angle of elevation to the top of a cliff is 18°41’.

First, convert the angle to degrees

= 18°41’

= 18.683 degrees.

let x is the height of the cliff.

Using Trigonometry

tan(18.683) = (x/991)

x = 335 ft

Answer:

B

Step-by-step explanation:

A quadratic has a maximum value when its leading coefficient is negative, as the parabola will be curving downwards.

For A, we have the function [tex]y=x^2+2x+2[/tex]

The leading coefficient here is 1, which is positive. So, A has a minimum value.

For B, we have the function [tex]y=-2x^2-3x+5[/tex]

In this case, the leading coefficient is -2, which is negative. So, B is curving downwards. Therefore, it has a maximum value.

Hence, B is our correct answer.

For C and D, the leading coefficient of C is 1/2 (coefficient in front of the parentheses) and the leading coefficient of D is 1 (coefficient of the squared variable). Since both are positive, both C and D have a minimum.

I used my massive huge smart brain to solve this

Answer:

0.08

Step-by-step explanation:

Answer:

Q:4A ($30) * 0.85 = $25.50

Q:4B ($18) * 0.85 = $15.30

Q:4C ($24.80) * 0.85 = $21.08

Q5:

(For six pack): $2.10 (each) * 8 = $16.80

(For eight pack): 3.12 (each) * 6 = $18.72

8 of the 6 packs would be the better deal.

Q6 (A): Elena is 142.24 cm tall.

(Formula is multiply the inches by 2.54. So, 56 times 2.54 is 142.24)

Q6 (B): Elena is 1.4224 meters tall.

(Formula is divide inches by 39.37. So, 56 divided by 39.37 is 1.4224)

Answer:

The value of x is 6

Step-by-step explanation:

AAS postulate of congruence is:

In the given figure

∵ JKL and JML are two triangles

∵ ∠K and ∠M are right angles

∴ ∠K ≅ ∠M

∵ ∠JLK and ∠JLM have the same mark

∴ ∠JLK ≅ ∠ JLM

∵ JL is a common side in the 2 triangles

∴ JL = JL

→ BY using the AAS postulate above

∴ ΔJKL ≅ ΔJML

→ From the result of congruency

∴ JK = JM

∵ Jk = 2x - 4

∵ JM = 4x - 16

→ Equate them

∴ 4x - 16 = 2x - 4

→ Subtract 2x from both sides

∴ 4x - 2x - 16 = 2x - 2x - 4

∴ 2x - 16 = -4

→ Add 16 to both sides

∵ 2x - 16 + 16 = -4 + 16

∴ 2x = 12

→ Divide both sides by 2

∴ x = 6
