1. Simplify 3 + 5[5 + (7 - 3) - 32]

Step-by-step explanation: 5

Answer:

Step-by-step explanation:

Raging River costs

y=9x

Paddlers costs

y=x+40

So they cost the same when y=y

9x=x+40

8x=40

x=5

So they cost the same for 5 hours.

Answer:

Regression to the mean fallacy

Step-by-step explanation:

It assumes that something has returned to normal because of corrective actions taken while it was abnormal. This fails to account for natural fluctuations. It is frequently a special kind of the post hoc fallacy.

Answer:

Step-by-step explanation:

Since it is ROTATED about the vertical line a cone is formed.

Answer:

75°

Step-by-step explanation:

All parallel lines will meet their transversal (the line going through them) at the same angle. We can imagine sliding line m up to line l until the two are overlapping, and naturally all of those angles at the intersection will overlap, too. ∠6 will overlap ∠2, so the two angles are congruent. If m∠6 = 75°, then m∠2 = 75°!

Answer: 3/5 of the park population is female, or 60 percent. How? 80:200 can be simplified to 40:100, and this in fraction form is 40/100. We can further simplify it by dividing both by 10 to get 4/10, and then by 2 to get 2/5. 5 - 2 = 3, so 3/5 is the answer.

I hope this helps!

Answer:

0.43 ft/hr

Step-by-step explanation:

dv/dt = 15ft³/hr

Height = 10ft

We are required to get dh/dt

h = 3r

r = h/3

Formula for volume = 1/3πr²h

We put value of h

1/3π(h/3)²h

= 1/3π(h²/9)h

= 1/3πh³/9

= πh³/29

dv/dt = 1/27π.3h²dh/dt

= dv/dt = πh²/9dh/dt

Remember dv/dt = 15

When we put this in we get

dh/dt = 15x9/3.142x10²

= 135/314.2

= 0.43 ft³/hr

Answer:

Second (middle) option

Step-by-step explanation:

You can clearly tell from the graph that the y intercept is at 0,0

in [tex]ax^2+bx+c[/tex], c is always the y value of the y-intercept

in this case the value is 0 so there shouldn't be a visible "c" in the equation, which is why the answer is the middle option

Answer:

S=9

Step-by-step explanation:

10[tex]\frac{1}{2}[/tex] - 1[tex]\frac{1}{2}[/tex] = 9

Answer:

s=9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

s+3/2=21/2

Step 2: Subtract 3/2 from both sides.

s+3/2−3/2=21/2−3/2

s=9

Answer:

x²(9x– 11)(9x + 11)

Step-by-step explanation:

81x⁴ – 121x²

The expression can be factorised as follow:

81x⁴ – 121x²

x² is common to both term. Thus:

81x⁴ – 121x² = x²(81x² – 121)

Recall:

81 = 9²

121 = 11²

Therefore,

x²(81x² – 121) = x²(9²x² – 11²)

= x²[(9x)² – 11²]

Difference of two squares

x²(9x– 11)(9x + 11)

Therefore,

81x⁴ – 121x² = x²(9x– 11)(9x + 11)

Answer:

X + Y = 180°

Step-by-step explanation:

We know that vertical opposite angles are equal

So,

Angle A = Angle B

So,

Assume;

Angle A = x

So,

Angle A + Y = 180°

So,

X + Y = 180°

Answer:

x = 3

Step-by-step explanation:

Since, 2 is the arithmetic mean of 1-2x and 3x.

Therefore,

[tex] \frac{1 - 2x + 3x}{2} = 2 \\ \\ \frac{1 + x}{2} = 2 \\ \\ 1 + x = 4 \\ \\ x = 4 - 1 \\ \\ x = 3[/tex]

5x-10= 3x+10

5x-3x= 10+10

2x÷2= 20÷2

x= 10

Step-by-step explanation:

as AD bisects them they will be two equal parts so

5x-10=3x+10

5x-3x=10+10

2x=20

divide both sides by 2 and

x=10

Answer:

y = (-1/2)x-9

Step-by-step explanation:

Answer:

x=4, x=-4

Step-by-step explanation:

x^2-16=0

Add 16 to both sides;

x^2-16+16=0+16

Simplify;

x^2=16

x=[tex]\sqrt{16}[/tex], x[tex]-\sqrt{16}[/tex]

[tex]\sqrt{16}[/tex]

=4

factor the number;16

[tex]\sqrt{4^2}[/tex]

=[tex]\sqrt{4}[/tex]

-[tex]\sqrt{16}[/tex]

Factor the number 16;

[tex]\sqrt{4^2}[/tex]

Answer:

x²+5x - 150 = 0

Step-by-step explanation:

Let the length be y and width be x

If the  length of a swimming pool is 10 more than 2 times the width, then;

y = 2x+10 ...1

Since the Area is 300m²

A = xy

300 = xy .... 2

Substitute 1 into 2

300 = x(2x+10)

300 = 2x²+10x

Rearrange

2x²+10x - 300 = 0

Divide through by 2

x²+5x - 150 = 0

This gives the required quadratic expression

Are there any other numbers to this question? I will be glad to help.
