Answer:

x = 81

Step-by-step explanation:

y = k√x

56 = k√49

56 = k(7)

Divide both sides by 7

8 = k

k = 8

------------------------

When y = 72

72 = 8√x

Divide both sides by 8

9 = √x

Square both sides

81 = x

x = 81

Answer:

Cost of 500 g of standard pack = € 7.50

Cost of 1 g of standard pack = 7.50/500

Cost of 100 g of standard pack = 7.50/500 ×100

= 7.50/5

= € 1.50

Answer:

x=-5

Step-by-step explanation:

Set " 4x+20" equal to 0 (4x+20=0)

Do the opposite operation of 20 (in this case is subtraction) and subtract 20 from both sides (4x+20-20=0-20).

You'll be left with 4x=-20.

Divide both sides by 4 (4x/4=-20/4).

4 divided 4 equals x.

-20 divided by 4 equals -5.

x=-5.

Answer:

10.

A = 12² - 2(6×5)

A = 144 - 2×30

A = 144 - 60

A = 84 in²

11.

A = π(12/2)² - (π3² + 3×6)

A = π36 - (π9 + 18)

A = π36 - (π3² + 18)

A = 113.04 - (28.26 + 18)

A = 66.8 yd²

12.

A = 9² - (10×2 + π3²)

A = 81 - (20 + 28.26)

A = 81 - 48.26

A = 32.7 m²

Answer:

36%

Step-by-step explanation:

18/50 = 0.36 --> 36%

The probability that a student preferred a class trip to the zoo given they are in 11th grade is; 0.36

Total number of eleventh graders is; 32 + 18 = 50

Number of class trip to the zoo given they are in the 11th grade = 18

Thus, probability that a student preferred a class trip to the zoo given they are in 11th grade is;

P(11th grade trip to zoo) = 18/50

P(11th grade trip to zoo) = 0.36

Answer:

306 toy cars

Step-by-step explanation:

since he has a total of 360 toy cars, and he keeps 85% on the wall, to find how many toy cars he keeps on his wall we have to find 85% of 360:

360*0.85=306

therefore, he keeps 306 toy cars on his wall

The number of toy cars does that Deion keeps on his wall is 306 cars.

Number of cars = 360

Percentage of the toy cars on his wall = 85%

Then, the number of toy cars that is kept in his wall will be:

= 85% × 360

= 0.85 × 360

= 306

In conclusion, 306 toy cars are kept on the wall.

Answer:

Step-by-step explanation:

It should be no stretch to understand that "increases" means the function is a growth function (+ sign), and "decreases" means the function is a decay function (- sign).

The multiplier in front (a) is the initial value — the value when t=0.

Answer:

y = 3x + 10

Step-by-step explanation:

Parallel lines have the same slope, so the line will have a slope of 3.

Plug in the slope and given point into y = mx + b, and solve for b:

y = mx + b

4 = 3(-2) + b

4 = -6 + b

10 = b

Plug in the slope and y intercept into y = mx + b

y = mx + b

y = 3x + 10

So, the equation of the line is y = 3x + 10

Answer:

0.6420758

Step-by-step explanation:

x = 275 ; n = 400

Phat = x / n = 275 / 400 = 0.6875

Z at 95% = 1.96

Confidence interval = phat ± margin of error

Margin of Error :

Z * √phat(1 - phat) / n

1.96 * √0.6875(0.3125) / 400

1.96 * 0.0231756

= 0.0454242

Lower boundary :

Phat - margin of error

0.6875 - 0.0454242

= 0.6420758

Ok ill find the slope for this graphhhhh

Step-by-step explanation:

-3/4

Answer:

A) -2 - i√3 , -2 + i√3

Step-by-step explanation:

Solve using quadratic formula

x² + 4x + 7 = 0

The Almighty Formula

= -b ± √b² - 4ac/2a

Where ax + bx² + c = 0

From the above question

a = 1, b = 4, c= 7

Hence,

-4 ± √4² - 4 × 1 × 7/2 × 1

-4 ± √16 - 28/2

=( -4 ± √-12)/2

Since

b² - 4ac < 0

We have two complex roots

Simplifying

( -4 ± √-12)/2

= -4/2 ± √-12/2

= -2 ± 2√3i/2

= -2 ± √3i

Therefore,

-2 - √3i , -2 + √3i

or

-2 - i√3 , -2 + i√3

Option A , is the correct answer

It's the 4th option.

Corresponding angles are congruent, so x =43. I hope this helps, have a great day!

Part (i)

The square has area of 12*12 = 144 square meters. From that, we carve out four quarter-circles from each corner, as the diagram shows. Imagine that we rearranged the quarter circles so that they would then form a full circle. This circle would have radius 6 (half of the 12 meters), so the area of the circle is pi*r^2 = pi*6^2 = 36pi exactly

The four white sections combine to an exact area of 36pi, which approximates to 36*3.14 = 113.04 square meters. Use more decimal digits in pi to get a better approximation.

Exact answer: 36pi square meters

Approximate answer: 113.04 square meters (when using pi = 3.14)

=======================================================

Part (ii)

Once we know what the white sections combine to, we can subtract that area from the total overall area of 144 m^2

We end up with 144 - 36pi as the exact area of the red section

This approximates to 144 - 36*3.14 = 30.96 m^2

Exact answer:  144 - 36pi square meters

Approximate answer: 30.96 square meters (when using pi = 3.14)

Step-by-step explanation:

The question is incomplete. The complete question is :

A wire that is 22 feet long connects the top of a pole to the ground. The wire is attached to the ground at a point that is 10 feet from the base of the pole. What is the height of the pole? Round to the nearest hundredth.

12.00 feet

19.60 feet

24.17 feet

38.40 feet

Solution :

Given the length of the wire = 22 feet

Horizontal distance between the pole and the point where the wire is attached = 10 feet

Therefore, from Pythagoras theorem, we get from the figure :

[tex]$AB^2=OA^2+OB^2$[/tex]

[tex]$OA^2=AB^2-OB^2$[/tex]

[tex]$OA^2=22^2-10^2$[/tex]

[tex]$OA^2=484-100$[/tex]

[tex]$OA^2=384$[/tex]

[tex]$OA=\sqrt{384}$[/tex]

      = 19.60 (approx)

Therefore, the height of the pole to the nearest hundredth is 19.60 feet.
