The computation shows that the difference in depth is 16 feet

<h3>How to calculate the value?</h3>

From the information, in January, it measured 6 ft deep, or |−6|, and in July, it was -22.

Therefore the difference between the depth will be:

= -6 - (-22)

= -6 + 22

= 16

Therefore, the difference in depth is 16 feet

Answer: 11.95

Explanation:

1.5 x 4.5 = 6.75, therefore there is 6.75 more inches than before so you add that to the 5.2 inches already on the ground
5.2 + 6.75 = 11.95

the middle School golf team is selling golf balls to raise $850 for new equipment they sell golf balls for $2 each a case has 24
aniked [119]

Answer:

The number of cases of golf ball that team needed to raise money for equipment  is 3 .

Step-by-step explanation:

Given as :

The amount needed for new equipment = $850

The cost of each golf ball = $2

The number of packs of golf ball in each case = 24

The number of golf ball in each pack = 6

Let The number of cases of golf ball team needed to raise money for equipment = n cases

Now, According to question

∵ 1 pack has 6 balls

so, 24 pack has 6 × 24

i.e 24 packs has 144 balls

So, The number of balls in each case` = 144 balls

<u>Again</u>

∵ cost of 1 ball = $2

So, cost of 144 balls = $2 × 144

i.e cost of 144 balls in each case = $288

<u>Again</u>

∵ The amount needed for new equipment = $850

So, The number of cases of golf ball team needed to raise money for equipment = \dfrac{amount needed for new equipmen}{cost of 144 balls in each case }

Or, n = \dfrac{850}{288}

∴ n = 2.9 ≈ 3

So, The number of cases of golf ball that team needed to raise money for equipment  = n = 3

Hence, The number of cases of golf ball that team needed to raise money for equipment  is 3 . Answer

The product of a number and -3 increased by 8 is 20
Roman55 [17]

Answer:

The answer would be -4.

Step-by-step explanation:

This is because the product of a number and -3 must be 8 less than 20, which is 12. And -3 times -4 is 12.

P and W are twice-differentiable functions with P(7)=2(W(7)). The line y=9+2.5(x-7) is tangent to the graph of P at x=7. The lin
fiasKO [112]

Using the product rule, we have

m(x) = x W(x) \implies m'(x) = xW'(x) + W(x)

so that

m'(7) = 7W'(7) + W(7)

The equation of the tangent line to <em>W(x)</em> at <em>x</em> = 7 has all the information we need to determine <em>m'</em> (7).

When <em>x</em> = 7, the tangent line intersects with the graph of <em>W(x)</em>, and

<em>y</em> = 4.5 + 2 (7 - 7)   ==>   <em>y</em> = 4.5

means that this intersection occurs at the point (7, 4.5), and this in turn means <em>W</em> (7) = 4.5.

The slope of this tangent line is 2, so <em>W'</em> (7) = 2.

Then

m'(7) = 7\cdot2 + 4.5 = \boxed{18.5}
