Answer:

x = 13

Step-by-step explanation:

<CBE = 180 - x

<BEC = x

<BCE = 180 - 90 - 64 = 26

180 - 3x + x + 26 = 180

206 - 2x = 180

2x = 26

x = 13

Answer:

The answer to this question is the percentage of the nitrogen is 17%

Answer:

x = 4

Step-by-step explanation:

Equation: 3x + 13 = 25

Step 1: Subtract 13 from both sides.

3x + 13 = 25

     - 13   - 13

      3x = 12

Step 2: Divide both sides by 3.

3x   =  12

Answer:

Area of ΔXYZ = n(r * r) square units

Step-by-step explanation:

Sides of ΔABC are 30 units, 40 units and 60 units.

Corresponding sides of another triangle XYZ are r times as long as the sides of ΔABC.

Therefore, sides of ΔXYZ will be, 30r units, 40r units and 60r units.

Perimeter of the triangle XYZ = 30r + 40r + 60r

                                                   = 130r units

If the area of ΔABC = n square units

Then the ratio of the area of ΔXYZ and ΔABC = (Ratio of the sides of ΔXYZ and ΔABC)²

[tex]\frac{\text{Area of triangle XYZ}}{\text{Area of triangle ABC}}=(\frac{\text{Side length of XYZ}}{\text{Side length of triangle ABC}})^2[/tex]

[tex]\frac{\text{Area of triangle XYZ}}{n}=(r)^2[/tex]

Area of ΔXYZ = nr² ≈ n(r * r)

Therefore, Option (3) will be the answer.

The expression that gives the perimeter of ΔXYZ is: 130r

The area of ΔXYZ = nr²

If A and B, with sides a and b respectively, are similar figures, therefore: area of A/area of B = a²/b².

Thus;

Given that the sides of ΔABC, which are 30, 40 and 60, are r times the corresponding sides of ΔXYZ, the sides of XYZ would be:

30r, 40r, 60r.

Perimeter of ΔXYZ = 30r + 40r + 60r = 130r

Given that the area of ΔABC is n units², therefore:

(area of ΔABC)/(area of ΔXYZ) = (side of ΔABC)²/(side of ΔXYZ)²

(n)/(area of ΔXYZ) = (30)²/(30r)²

n/area of ΔXYZ = 1/r²

nr² = area of ΔXYZ

area of ΔXYZ = nr²

Therefore, the expression that gives the perimeter of ΔXYZ is: 130r

The area of ΔXYZ = nr²

Answer: Shop A

15% of 240 is 36 and 240-36 is 204 so shop B is more expensive.

The price of a telephone at shop A is less than the price of a telephone at shop B. Then the telephone is bought from shop A.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

The price of a telephone is $200 in shop A and $240 in shop B. If you get a 15% discount shop B.

The price of the telephone after the discount at shop B will be given as,

⇒ (1 - 0.15) x $240

⇒ 0.85 x $240

⇒ $204

The price of a telephone at shop A is less than the price of a telephone at shop B. Then the telephone is bought from shop A.

Answer:

A.) 0.7647 b.) 13/ 16 C.) 0.9412 D.) 8.743 * 10^-10

Step-by-step explanation:

A)

Number of cards per suit = 13

Nunber of suits = 4

Probability = required outcome / Total possible outcomes

P(1) = probability of picking a card from a certain suit

P(1) = 13 / 52

Hence, probability that 2nd card will be from a suit different from the first :

Total possible outcomes = (52 - 1) = 51

Required outcomes = (13 * 3) = 39

= 39 / 51

= 0.7647

B.)

First toss being head :

Required outcome = H = 1

Total possible outcomes = T or H = 2

P(H) = 1/ 2

For 5 tosses

Total possible outcomes = 2^n = 2^5 = 32

Exactly 2 heads = 10

P(exactly 2 heads) = 10/32 = 5/16

1/2 + 5/16 = (8 + 5) / 16 = 13/16

c)

1 - P(both top and bottom are hearts)

Number of hearts = 13 ; number of cards = 52

P(both are hearts) = 13/52 * 12/51 = 0.05882

1 - 0.05882

= 0.94117

= 0.9412

d)

Either all marbles are red OR all marbles are green OR all marbles are blue

Total number of marbles = (20 + 20 + 20) = 60

Probability that all 15 marbles are of a certain color :

(20/60 * 19/59 * 18/58 * 17/57 * 16/56 * 15/55 * 14/54 * 13/53 * 12/52 * 11/51 * 10/50 * 9/49 * 8/48 * 7/47 * 6/46)

(2.9146E−10) + (2.9146E−10) + (2.9146E−10)

= 8.7438E−10

= 8.743 * 10^-10

Answer:

y=3/2x

Step-by-step explanation:

Just find a fraction that is greater than one, but less than two and plug it in right next to x. I chose 3/2, but you can choose anything else if you like.

The equation of a line that has a slope that is greater than 1

but less than 2 in slope-intercept form is y = (3/2)x + b.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.∴

Given a line has a slope of greater than 1 and less than two,

∴ We can take any value from 1.01 to 1.99, for our convenience let us take 1.5which is 3/2.

So, the equation of the line will be y = (3/2)x + b.

Answer:

(1) The required ratio of spirit to varnish is 1:3.

(2) You need 80 ml of mineral spirit.

(3) The ratio of tapestries' heights to width is 3:2.

Step-by-step explanation:

(1) If you need to mix 25% mineral spirit to the varnish, then the solution would contain 25% mineral spirit and 75% varnish.

So, [tex]\frac{spirit}{varnish}=\frac{25}{75}[/tex]

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

Thus, The required ratio of spirit to varnish is 1:3.

(2) If you use 240ml of varnish, then this quantity is 75% of the total solution or ration of varnish to the total solution will be 3:4.

Let [tex]x[/tex] be the quantity of total solution.

Then, [tex]240:x=3:4[/tex].

⇒[tex]\frac{240}{x}=\frac{3}{4}[/tex]

⇒[tex]3x=240*4[/tex]

⇒[tex]x=\frac{240*4}{3}[/tex]

⇒[tex]x=320[/tex]

That is, total solution is 320 ml.

Now, Spirit = Total solution - Varnish

⇒Spirit = 320ml-240ml

⇒Spirit = 80ml

Hence, if you use 240 ml of varnish, you need 80 ml of mineral spirit.

(3) Robison's tapestries all measure 1.5m long and 1m wide. First, we express dimensions in whole numbers by multiplying them by 10.

Then, dimensions are 15m long and 10m wide.

Now, Height : Width = 15:10

⇒[tex]\frac{Height}{Width} =\frac{15}{10}[/tex]

⇒[tex]\frac{Height}{Width} =\frac{3}{2}[/tex]

Hence, the ratio of tapestries' heights to width is 3:2.
