What is ratio of two quantities?

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b or [tex]\dfrac{a}{b}[/tex]

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).

Suppose that we've got a = 6, and b= 4, then:

[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]

Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.

Same thing happens for 3 quantities and more such quantities.

So if its given that Oli, Sam, and Tim's share (total  £360) are in the ratio 3:2:1, that means some common factor (lets call it 'x') must be cancelled off as 3+2+1 don't equate to 360.

So, we have:

Oli's share = 3xSam's share = 2xTim's share = 1x = x

Their total evaluates to 360 (in euros).

(we don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)

Thus, we get:

[tex]3x + 2x + x = 360\\(3+2+1)x = 360\\6x = 360\\\\\text{Dividing both the sides by 6}\\\\\dfrac{6x}{6} = \dfrac{360}{6}\\\\x = 60[/tex]

Thus, we get:

Oli's share = 3x = 3×(60) = £180Sam's share = 2x = 2×(60) = £120Tim's share = 1x = x = £60

Thus, the amount that Sam get (the share of Sam) is £120

a solid metal cone with radius of base 12 cm and height 24 cm is melted to form spherical solid balls of diameter 6 cm each. Find the number of the balls thus formed​

Answers

Answer:

32 solid balls are formed.

Step-by-step explanation:

Let suppose that volume of the cone is equal to the total volume of balls, of which we derive the following formula:

[tex]\frac{1}{3}\cdot \pi\cdot R^{2}\cdot h = \frac{1}{6}\cdot \pi \cdot n \cdot D^{3}[/tex] (1)

Where:

[tex]R[/tex] - Radius of the base of cone, measured in centimeters.

[tex]h[/tex] - Height of cone, measured in centimeters.

[tex]D[/tex] - Diameter of sphere, measured in centimeters.

[tex]n[/tex] - Number of balls, no unit.

Then, we clear the number of balls:

[tex]2\cdot R^{2}\cdot h = n\cdot D^{3}[/tex]

[tex]n = \frac{2\cdot R^{2}\cdot h}{D^{3}}[/tex]

If we know that [tex]R = 12\,cm[/tex], [tex]h = 24\,cm[/tex] and [tex]D = 6\,cm[/tex], then the number of balls is:

[tex]n = \frac{2\cdot (12\,cm)^{2}\cdot (24\,cm)}{(6\,cm)^{3}}[/tex]

[tex]n = 32[/tex]

32 solid balls are formed.

A double box-and-whisker plot represents the stock prices of Company A and Company B over a 30-day period. Both companies have a minimum price of $3 and a maximum price of $10. The median price for Company A is $6 and the median price for Company B is $9. Which company is more likely to have a symmetric box-and-whisker plot? Explain.

Answers

Answer:

company a

Step-by-step explanation:

It is probably company a because if you make a box and whisker plot in your head the median of 6 would be more in between 3 and 10 than 9. If the median were 9 it would probably be skewed. If 6 is near the middle the box and whisker plot would look more symmetric

Answers

Answer:

x = 55

Step-by-step explanation:

ABCD is a paralellogram, m∠ABC = 2x + 15, m∠BCD = x

m∠ABC + m∠BCD = 180° (same side interior angles)

2x + 15 + x = 180

3x + 15 = 180 -15

3x = 165

x = 55

rename 1/2 and 2/3 as fractions with denominators of 6.then add the renamed fractions. write the sum as a mixed number.

Answers

Answer:

1 and 1/6

Step-by-step explanation:

To rename a fraction you multiply both numbers by however many times the original denominator goes into the new one.

2 goes into 6 three times.

1 times 3 is 3

and 2 times 3 is 6

so 1/2=3/6

3 goes into 6 twice

2 times 2 is 4

and 2 times 3 is 6

so 2/3=4/6

to add fractions you add the numerators while keeping the denominators the same.

3+4=7 so:

3/6+4/6=7/6

6/6=1

so 7/6 contains 1 whole

once you take that out you have 1/6 left over

Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.

Step 1:

Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.

Step 2:

Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.

Step 3:

Combine like terms: (18 + 24) squared = 30 squared.

Step 4:

Evaluate each side: 1764 not-equals 900.

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?

The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.

Answers

Answer:

1) 35

2) 125

Step-by-step explanation:

1)

angle adc = x

x+ 90 + 20 = 180                (triangke sum property)\

x = 180 - 110 = 70

angle bdc = 70/ 2 = 35          ( the median cuts the angle into 2)

2) cbd = x = 125

x + c + bdc = 180

x + 35 + 20 = 180

x = 180 - 55 =  125

Then simplify -6(x+9) to get -6x-54

Now you have 4x+6=-6x-54

Move all of the coefficients to one side:

10x+6=-54

Move all of the constants to the other side:

10x=-60

Divide each side by 10:

In the ​triangle XYZ​, the measure of ​∠XYZ​ is 104°, and the measure of ∠YZX is 19°. What is the measure of ∠ZXY?

Answers

Answer:

∠ZXY = 57°

Step-by-step explanation:

According to angle sum property of a triangle, sum of all the angles of the triangle is [tex]180[/tex]°.

In ΔXYZ,

∠XYZ + ∠YZX + ∠ZXY = 180°

Put ∠XYZ = 104°, ∠YZX = 19°

104° + 19° + ∠ZXY = 180°

123° + ∠ZXY = 180°

∠ZXY = 180° - 123°

∠ZXY = 57°

Therefore,

∠ZXY = 57°
