What number is 25% of 400 please show work thank you
ANEK [815]

Answer:

100

Step-by-step explanation:

well, you can just use a calculator, or your mind if that's possible, to solve this.

at least, what i think you're asking.

400 × 0.25 = 100.

this one is extra easy because you should know that 25% is a quarter, and 400 can just be divided by 4 to get your answer.

The sign below is located at the start of Pinecone trail and shows the distances from the sign to different points of interest a
schepotkina [342]

Answer:

Total distance = 53/4 miles = 13.25 miles

Step-by-step explanation:

Sage hiked from the start of the trail to Lookout Point.

Distance = 8 3/4 miles = 35/4 miles

She then hiked back to Giant Boulder

This means she traveled an additional

8 3/4 miles  - 4 1/4 miles = 35/4 mi - 17/4 mi = 18/4 mi = 9/2 mi

The total distance traveled by sage is the sum of both trajectories

Total distance = 35/4 miles + 9/2 miles =  53/4 miles

Total distance = 13.25 miles

What is the axis of symmetry for f(x) = 2x2 − 8x 8? x = −2 x = −3 x = 3 x = 2
Tatiana [17]

<span>The first part of the quadratic formula, x = - b/2a, is the equation of the axis of symmetry, and the x-coordinate of the vertex. </span>

<span>In standard form: - 2x² + 8x - 5 = 0, a = - 2, b = 8, c = - 5 </span>

<span>The axis of symmetry: x = - 8/2(- 2) = - 8/- 4 = 2 </span>

<span>Go back and solve for y to find the y-coordinate of the vertex. </span>

<span>y = - 2(2)² + 8(2) - 5 </span>

<span>y = - 2(4) + 16 - 5 </span>

<span>y = - 8 + 16 - 5 </span>

<span>y = 3 </span>

<span>Vertex is (2, 3)</span>
