Answer:

BD = 19

Step-by-step explanation:

Given

CD = 2x

BD = 3x + 4

BC = 2x -1

Required

Find BD

Since C is on BD, we have:

BD = BC + CD

Substitute values for BD, BC and Cd

3x + 4 = 2x - 1 + 2x

Collect Like Terms

3x - 2x - 2x = -1 - 4

-x = -5

Multiply through by -1

x = 5

Substitute 5 for x in BD = 3x + 4

BD = 3 * 5 + 4

BD = 19

Zoe and Hannah share tips in the ratio 3:7. Last week, Zoe received £24. How much did Hannah receive last week?​
frozen [14]

Answer:

56

Step-by-step explanation:

If the ratio of Zoe; Hannah is 3:7 and Zoe got 24 than we have to divide the 24 by 3 so we can multiply it by 7. This is because since the Zoe is the 3 and it isn't a 1 it isn't the starting point for either of the ratios we cannot multiply the 24 by 7.

24 ÷ 3 = 8

Now we multiply the 8 by 7 so that we know have many tips Hannah made

8 × 7 = 56

Hannah made 56 in tips

Vesnalui [34]

Answer: 18.125 lbs

Explanation: The baby weighed 18.125 pounds at the end of eight months.

The baby weighed 7.25 lbs at birth. Eight months later, he weighed 2.5 or 2½ times its birth weight. Multiply 7.25 by 2.5  (which equals 18.125).

So now eight months later, he's 18.125 pounds.

1. BOTANICAL GARDENS One of the displays at a botanical garden is an herb garden planted in the shape of a square. The square me

The pathway is 8.46 yards.

<h3>How to find the length of the pathway?</h3>

To find the length of the pathway, it is required to find how long is the diagonal line from one corner of the herb garden to the opposite corner. As shown in the image attached.

The general formula for this is:

  • d = a√2 or diagonal = side√2

Let's apply this formula:

  • d= 6 √2
  • d= 6 x 1.41
  • d= 8.46 yards

Suppose a soccer goalie punted the ball in such a way as to kick the ball as far as possible down the field. The height of the b
Alexxx [7]

Answer:

57.98 yards

Step-by-step explanation:

When the ball is on the ground, the height is y=0, therefore:

y=-0.017x^2+0.98x+0.33

0=-0.017x^2+0.98x+0.33

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

x=\frac{-0.98\pm\sqrt{0.98^2-4(-0.017)(0.33)}}{2(-0.017)}

x_1=57.98184919

x_2=-0.3347903693

Since distance cannot be negative, the ball landed 57.98 yards down the field from where the goalie kicked the ball.
