Explanation:

8 jars need 1.8 kg of caster sugar.

Cut each value in half to see that 4 jars need 0.9 kg of caster sugar.

Convert 0.9 kg to grams to get 900 grams (multiply by 1000 to go from kg to grams).

Jayne needs 900 grams of caster sugar. She has 860 grams already, which means she needs an additional 900-860 = 40 grams

Answer:

x= 44.1

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hypotenuse

sin 27 = 20/x

x sin 27 = 20

x = 20 / sin 27

x= 44.05378529

Rounding to the nearest tenth

x= 44.1

Answer:

No line of symmetry no angle and order of rotational symmetry

There is no line of symmetry, no angle, and order of any rotational symmetry so option (C) will be correct.

If two figures look an exact shape but their size could be small or big then both figures are called similar figures.

When anything has identical pieces facing one another or revolving around an axis, it is said to be symmetrical.

For example, a square with a side of 10 cm and another with a side of 20 cm both square will be similar.

Given the figure and axis for symmetry

If we fold across the line of symmetry then we can see that neither party can fully cover another

Hence the given figure will not have any symmetry.

Answer:

The mean score in the maths test for class B was 12.41 points.

Step-by-step explanation:

Given that Class A has 12 pupils and class B has 29 pupils, and both classes sit the same maths test, and the mean score for class A is 52 while the mean score for both classes is 24, to determine what is the mean score in the maths test for class B the following calculation must be performed:

52 x 12 + X x 29 = 24 x (12 + 29)

624 + 29X = 24 x 41

624 + 29X = 984

29X = 984 - 624

X = 360/29

X = 12.41

Therefore, the mean score in the maths test for class B was 12.41 points.

Step-by-step explanation:

8x-9+2+9x=180 degree(being co interior angles)

17x-7=180

17x=180+7

x=187/17

x=11 degree

Answer:

11

Step-by-step explanation:

consecutive interior angles always equal to 180 degrees, so you would add both equations together and equal it to 180 degrees. you would then simplify and solve.

8x-9 + 2+9x = 180

-7 + 17x = 180

-7+7     180+7 = 187

17x = 187

17x/17 = 187/17

x=11

Answer:

221.87 feet

Step-by-step explanation:

Given that,

A 525 ft cable runs from the top of an antenna to the ground.

The angle of elevation made by the ground to the top of an antena 25°

We need to find the height of the antenna.

Using trigonometry,

Hypotenuse, H = 525 ft

θ = 25°

So,

[tex]\sin\theta=\dfrac{P}{H}\\\\P=H\sin\theta\\\\P=525\times \sin(25)\\\\P=221.87\ ft[/tex]

So, the height of the antenna is equal to 221.87 feet.

Answer:

x = 8

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

Step-by-step explanation:

0 = (x - 8)(3x - 5)

(x - 8)(3x - 5) = 0

x(3x - 5) - 8(3x - 5) = 0

3x² - 5x - 8(3x - 5) = 0

3x² - 5x - 24x + 40 = 0

3x² - 29x + 40 = 0

[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]

Ignore the A before the ±. It wouldn't let me type it correctly.

3x² - 29x + 40 = 0

a = 3

b = - 29

c = 40

[tex]x=\frac{-(-29)±\sqrt{(-29)^{2}-4((3)(40)) } }{2(3)}[/tex]

[tex]x=\frac{-(-29)±\sqrt{841-4((3)(40)) } }{2(3)}[/tex]

[tex]x=\frac{29±\sqrt{841-480} }{2(3)}[/tex]

[tex]x=\frac{29±\sqrt{361} }{2(3)}[/tex]

[tex]x=\frac{29±19 }{2(3)}[/tex]

[tex]x=\frac{29±19 }{6}[/tex]

Two separate equations

[tex]x=\frac{29+19 }{6}[/tex]

[tex]x=\frac{48 }{6}[/tex]

x = 8

[tex]x=\frac{29-19 }{6}[/tex]

[tex]x=\frac{10 }{6}[/tex]

[tex]x=\frac{5 }{3}[/tex]

Answer: Choice D)  [tex]\sqrt{2}:1[/tex]

Explanation:

The diagram shows the hypotenuse is [tex]6\sqrt{2}[/tex] units long and the leg is 6 units long. This forms the ratio [tex]6\sqrt{2}:6[/tex] where the hypotenuse is listed first. This is because it's mentioned first in the instructions (when compared to the other side 6).

We then divide both parts of the ratio [tex]6\sqrt{2}:6[/tex] by 6 to end up with the final answer [tex]\sqrt{2}:1[/tex]. This ratio says "the hypotenuse is exactly [tex]\sqrt{2}[/tex] times that of the leg length". This only applies to 45-45-90 triangles.

Option D is correct, √2 : 1 represents the ratio of the hypotenuse to the given side.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The given triangle is a right triangle.

6√2 is the hypotenuse of the triangle.

We have to find the ratio of the  hypotenuse to the given side.

Let the adjacent side length is 6.

The ratio is hypotenuse by the side length

6√2/6

The 6 on numerator and denominator will be cancelled.

√2/1

Hence, √2 : 1 represents the ratio of the hypotenuse to the given side.

Answer:

5.3×10⁻¹¹ m

Step-by-step explanation:

Applying,

v = 2πr/t................ Equation 1

Where v = speed of the electron in the orbit, r = radius of the orbit, t = time, π = pie

make r the subject of the equation

r = vt/2π................ Equation 2

From the question,

Given: v = 2.2×10⁶ m/s, t = 1.5×10⁻¹⁶ s

Constant: π = 3.14

Susbtitute these values into equation 2

r = (2.2×10⁶×1.5×10⁻¹⁶)/(3.14×2)

r = (3.3×10⁻¹⁰)/6.28

r = 5.3×10⁻¹¹ m

Hence the radius of the orbit is 5.3×10⁻¹¹ m

Answer:

The radius of the orbit is: [tex]R=0.525 \AA[/tex]

Step-by-step explanation:

The period of a circular motion is the time to complete one orbit, then:

[tex]T=1.5*10^{-16}s[/tex]

Now, let's recall the tangential speed can be written as:

[tex]v=\frac{2\pi R}{T}[/tex]

R is the radius of the motion.

Let's solve the above equation for R.

[tex]R=\frac{vT}{2 \pi}[/tex]

[tex]R=\frac{2.2*10^{6}1.5*10^{-16}}{2 \pi}[/tex]

[tex]R=\frac{2.2*10^{6}1.5*10^{-16}}{2 \pi}[/tex]

[tex]R=5.25*10^{-11} \: m[/tex]

Therefore, the radius of the orbit is: [tex]R=0.525 \AA[/tex]
