Complete Question:

The profile of a dam is modeled by the equation y = 24 (StartFraction x Over 10 EndFraction) squared, where x represents horizontal distance and y represents height, both in meters.

Point Z is at a horizontal distance of 15 meters from the left-most point of the dam. What is the height of the dam at point Z?

Answer:

The height is 36 meters

Step-by-step explanation:

Given

[tex]y = 24 * \frac{x}{10}[/tex]

Required

The interpretation of the question is to determine the value of y when x = 15

Substitute 15 for x in: [tex]y = 24 * \frac{x}{10}[/tex]

[tex]y = 24 * \frac{15}{10}[/tex]

[tex]y = 24 * 1.5[/tex]

[tex]y = 36[/tex]

The height is 36 meters

the answer is C.

Step-by-step explanation:

(50+40)/2=45

Answer:

so to average 45mph for 4 hours, he had to drive 4x45 miles total

4x45= 180miles

now we know he drove 120 miles (3x40) in the first 3 hours.

so he drove 180-120= 60 miles in the last hour.

60mph

Answer:250 feet

Step-by-step explanation: a rectangle has four sides, now you have two numbers, 70 and 50. so you do  4÷2 = 2 now take 2 a multiply it 70(140) now do it with 50(100) now add em (250) it is how i do it

Answer:

Step-by-step explanation:

Part A:

8t + 5h = 220

t + 5h = 112

Part B:

T-shirt cost $13.50

Hat cost $22.40

Answer:

[tex]Boys = 1 /4[/tex]

[tex]Total =112[/tex]

Step-by-step explanation:

Given

[tex]Girls= 3/4[/tex] ---  missing information

[tex]Boys = 28[/tex]

Solving (a): The fraction that are boys

We have:

[tex]Girls= 3/4[/tex]

This implies that

[tex]Boys = 1 - Girls[/tex]

[tex]Boys = 1 - 3/4[/tex]

[tex]Boys = 1 /4[/tex]

Solving (b): Students in the class

If 1/4 are boys, then:

[tex]Boys = \frac{1}{4} * Total[/tex]

We also have that: [tex]Boys = 28[/tex]

So:

[tex]28= \frac{1}{4} * Total[/tex]

[tex]28 * 4 = Total[/tex]

[tex]112= Total[/tex]

[tex]Total =112[/tex]

Answer:

1/8th of a foot

Step-by-step explanation:

All you have to do is divide the 5 feet by how ever many sections there are in this case it's 8.

5 / 8 = 0.625 = 1/8

Answer:

1.5 moles

Step-by-step explanation:

number of moles = no. of particles / Avagadro number

therefore, number of moles. = 9.033 * 10^23 / 6.022 * 10^23

therefore, no. of moles = 1.5

There are 1.5 moles in 9.033 * 10^23 Lithium atoms.

Answer:

37:31 or any other way of writing 37 to 31

Step-by-step explanation:

Write the ratio the same way the question asks, there are 37 girls and 31 boys. This cannot be simplified.

Answer:

x = 2

y = 152°

Step-by-step explanation:

✔️9x + 10 = 15x - 2 (corresponding angles theorem)

Collect like terms

9x - 15x = -10 - 2

-6x = -12

Divide both sides by -6

x = -12/-6

x = 2

✔️y + (15x - 2) = 180° (same-side interior angle theorem)

Plug in the value of x

y + (15*2 - 2) = 180

y + 28 = 180

y = 180 - 28

y = 152

Answer:

B : 10 cm^3

Step-by-step explanation:

L x W x H = V

4cm x 2cm x 1 1/4 (1.25) = 10cm^3

1 1/4 = 4 x 1 = 4 + 1 = 5/4 = 1.25

Hope this helps!

I am pretty sure this is right.  

Answer:

9600

Step-by-step explanation:

y varies inversely with the square of x

y=k/(x^2)

for some non-zero constant k

y=6 when x=4

6=k/(4^2)

k=96

y=96/(x^2)

x=0.1

y=96/(0.1^2)

y=9600

Answer:

yes, he still needs all the buses he hired

Step-by-step explanation:

768 people/56 people per bus = 13.71, so 14 buses

768 - 19 = 749 people going

749people/56 people per bus = 13.37, so still need 14 buses

Answer:

[tex]\boxed{12u^3+8u^2-6u+9}[/tex]

Step-by-step explanation:

[tex](8u^3+8u^2+6)+(4u^3-6u+3) = 8u^3+8u^2+6+4u^3-6u+3[/tex]

Once

[tex]8x+4x = 12x, \text{ as } x = u^3[/tex]

[tex]8u^3+8u^2+6+4u^3-6u+3 = 12u^3+8u^2+6-6u+3 = \boxed{12u^3+8u^2-6u+9}[/tex]

You don't need to factor.

Answer:

Step-by-step explanation:

The Cauchy integral formula states that the values of a holomorphic function inside a disk are determined by the values of that function on the boundary of the disk. More precisely, suppose f : U → C f: U \to \mathbb{C} f:U→C is holomorphic and γ is a circle contained in U.
