Answer:

$6.96

Step-by-step explanation:

0.25 pound = $1.74

for 1 pound multiply by 4, since there are four 0.25 (quarters) to 1 pound.

1.74*4 = 6.96

Answer:

I think it is 6.94

Step-by-step explanation:

0.25 is 1/4 of a dollar so we should multiply 1.74 by 4 and we get 6.94 dollars for  1 pound of tuna salad

Two walls of a canyon form the walls of a steady flowing river. From a point on the shorter wall, the angle of elevation to the
Sunny_sXe [5.5K]

Answer:

x is approximately 226.3 feet

y is approximately 308.6 feet

z is approximately 226.3 feet

Step-by-step explanation:

The given parameters of the walls are;

The angle of elevation from the top of the shorter wall to the top of the opposing wall, θ₁ = 20°

From the diagram, the angle of depression from the top of the shorter wall to the bottom of the opposing wall, θ₂ = 45°

The distance from the bottom of the shorter wall to the base of the opposing wall, l = 320 feet

x = The height of the shorter wall = l × sin(θ₂)

∴ x = 320 feet × sin(45°) = 320 feet × (√2)/2 = 160·√2 feet ≈ 226.3 feet

∴ x ≈ 226.3 feet

By observation, we have;

y = x + z × tan(θ₁)

Where;

z = l × cos(θ₂)

∴ y = 160·√2 + 320 × cos(45°) × tan(20°) ≈ 308.6

y ≈ 308.6 feet

z =  l × cos(θ₂)

∴  z = 320 × cos(45°) = 160·√2 ≈ 226.3

z ≈ 226.3 feet.

Answer:

(-7,4]

Step-by-step explanation:

I'm going to assume that you need this in interval form

The domain is just asking for all the possible x values

The x value that's furthest to the left is -7 and because it's an open circle we write ( instead of [

the furthest to the right the line goes is 4 and because the circle is closed it's written with ]

but it all together and get

Find the values of y which makes the expression (2y + 7) /(y2 - 2y - 15) undefined?
sammy [17]

The  given expression becomes undefined when y=5 or y = -3. The answer is option D.

Step-by-step explanation:

The value of the given expression becomes undefined when the denominator equals 0.

Hence to find the value of y which makes the expression undefined, we can equate the value of the denominator to zero and solve it .

Step 1

  Equate the denominator to 0.

  y^{2}  - 2y -15 = 0

Step 2

   Solve the above equation to get the value of y.

     y^{2}  - 2y -15 = 0

    => (y-5)(y+3) =0 [ Roots of the quadratic equation]

   => y = 5 or y = -3.

Hence when y = 5 or y = -3 the denominator becomes 0, which makes the expression (2y+7)/0  and hence it is undefined.
