Answer:

[tex] m\angle ABC = 51°[/tex]

Step-by-step explanation:

11. By inscribed angle theorem:

[tex] 83°=\frac{1}{2} \times (9x+40)°\\\\

83°\times 2 = (9x+40)°\\

166°= (9x+40)°\\

166 = 9x + 40\\

166 - 40 = 9x\\

126 = 9x\\\\

x = \frac{126}{9}\\\\

\huge \red {\boxed {x = 14}} [/tex]

12. Again by inscribed angle theorem:

[tex] (5x+11)°=\frac{1}{2} \times (16x-26)°\\\\

2\times (5x+11)°= (16x-26)°\\

(10x+22)°= (16x-26)°\\

10x + 22 = 16x - 26\\

22+26 = 16x - 10x\\

48= 6x\\\\

x = \frac{48}{6}\\\\

\huge \purple{\boxed {x = 8}}\\

m\angle ABC = (5x+11)°\\

m\angle ABC = (5\times 8+11)°\\

m\angle ABC = (40+11)°\\

\huge \orange{\boxed {m\angle ABC = 51°}} \\

Answer:

Step-by-step explanation:

Emma jogs 2 miles along the beach in 1/3 of an hour. At a constant rate, the distance that she jogs on 1 hour would be

Let x represent the number of mikes that she would jog in 1 hour.

If 2 miles = 1/3 of an hour, then

x = 1 hour

Cross multiplying, it becomes

x × 1/3 = 2 × 1

x/3 = 2

x = 3 × 2 = 6 miles

The equivalent rate with a denominator of 1 is 6/1 miles

Answer:

the speed of the plane when there is no wind is 212.25 mi/hr

Step-by-step explanation:

Let v represent the speed of the plane without wind.

Wind speed = 20.1 mi/hr

The resultant speed with wind is;

v + 20.1 mi/hr

The resultant speed against wind is;

v - 20.1 mi/hr

Let t represent the time for the travel.

With wind;

(v+20.1)t = 630 ......1

Against wind;

(v-20.1)t = 521 ......2

Divide equation 1 by 2

(v+20.1)/(v-20.1) = 630/521

Cross multiply;

521(v+20.1) = 630(v-20.1)

Collecting like terms;

v(630-521) = 20.1(630+521)

v = 20.1(1151)/109

v = 212.25 mi/hr

the speed of the plane when there is no wind is 212.25 mi/hr

Hello!

[tex]\boxed{ \bf Sheila~will~need~about~7~containers.}[/tex]

__________________________________________________

First, we will need to convert the mixed fractions to improper fractions.

Numerators: (2 · 11) + 1 = 23

                      (4 · 1) + 3 = 7

Denominators: stay the same.

11 [tex]\frac{1}{2}[/tex] ⇒ [tex]\frac{23}{2}[/tex]

1 [tex]\frac{3}{4}[/tex]  ⇒ [tex]\frac{7}{4}[/tex]

Next, we must divide these two fractions:

[tex]\frac{23}{2}[/tex] ÷ [tex]\frac{7}{4}[/tex]

We must flip the divisor into a reciprocal:

[tex]\frac{23}{2}[/tex] ÷ [tex]\frac{4}{7}[/tex]

Change the division sign to multiplication and multiply:

[tex]\frac{23}{2}[/tex] × [tex]\frac{4}{7}[/tex] = [tex]\frac{92}{14}[/tex]

To find out how many containers will be needed, simply convert this fraction to a decimal by dividing the numerator by the denominator.

92 ÷ 14 = 7 (Rounded)

Answer: 10.9 cm

Step-by-step explanation:

The equation to find the area of a triangle is

Base x height x 1/2 = area

Since you are given the area, rearrange or “do the opposite” to find the base

(Area x 2 ) / height = base

30 x 2 = 60

60/ 5.5 = 10.9

Hope this helped :)

Answer:

x = 2,444

Step-by-step explanation:

3(12x - 24) = 16

36x - 72 = 16

36x = 16 + 72

36x = 88

x = 88/36

x = 2,444

Answer:

Arc EPF is 240°

Step-by-step explanation:

Since the quadrilateral, EFGH is a trapezoid and EF is parallel to GH, we have;

∠HGF + ∠GFE = 180°

∠GHE + ∠GFE = 180°

∠HGF + ∠HEF = 180°

∴∠HEF = ∠GFE

In ΔHEF and ΔGFE

∠EHF = ∠EGF (Angles subtending the same segment)

With side EF common to both triangles and ∠HEF = ∠GFE , we have;

ΔHEF ≅ ΔGFE (Angle Angle Side rule)

Hence, side FG = EH

For cyclic trapezoid side FG = EH

The base angles subtended by GH = 70

Arc EH = x² - 2·x

Arc FG = 56 - 3·x

Therefore;

70 + x² - 2·x + 56 - 3·x + arc EPF = 360 .............(1)

Also since the equation of a circle is (x-h)² + (y-k)² = r², where the center of the circle is (h, k), then as EF is a displacement of say z from GH, then arc EH = FG which gives;

x² - 2·x = 56 - 3·x

x² - 2·x - 56 + 3·x = 0

x² + x - 56 = 0

(x - 7)(x + 8) = 0

Therefore, since x > 0 we have x = 7

Plugging in the value of x into the equation (1), we have

70 + 7² - 2·7 + 56 - 3·7 + arc EPF = 360 .............(1)

70 + 70 + arc EPF = 360

arc EPF = 360 - 140 = 240°.

Answer:

c

Step-by-step explanation:

Answer:

There is a 1/3 chance of getting a hobbit, and a 0.1/11 chance of getting an umbrella.

Answer:

a . 9/25

b. 13/25

c. 3/5

Step-by-step explanation:

Firstly, we add the number of balls to get the total number of balls = 3 + 2 = 5 balls

P(R) = number of red/total number of balls = 3/5

P(B) = number of blue/total number of balls = 2/5

Since the experiment is with replacement, whatever ball picked would be returned

a. Probability of both balls being red = P(R) * P(R) = 3/5 * 3/5 = 9/25

b. Probability of both balls being same color;

That is : probability of both balls being red or both being blue

Mathematically that would be;

P(R) * P(R) or P(B) * P(B)

whenever we have or in probability, what we do is to add ;

= (3/5 * 3/5) + (2/5 * 2/5) = 9/25 + 4/25 = 13/25

C. at least one of the balls is red

what this means is that both are red or one of the two is red.

Mathematically;

P(R) * P(R) or P(B) * P(R)

= (3/5 * 3/5) + (3/5 * 2/5)

= 9/25 + 6/25 = 15/25 = 3/5

Explanation:

Understanding what a variable stands for is essential when substituting values or interpreting answers.

__

For example, consider the equation for arc length:

  s = rθ

The variables stand for ...

For proper use of this formula, it is essential to understand that the variables s and r have the same units of length. The angular measure is not degrees (or grads), but is the unitless measure of angles known as radians.

It would be erroneous to use feet or yards for 'r' and expect the arc length 's' to be in miles. Similarly, it would be erroneous to substitute 30° for θ, instead of the equivalent radian measure π/6.

These errors can be avoided if the variables are properly described.

Answer:

The 98% confidence interval for the population proportion of purchases paid with a major credit card is (0.1786, 0.3958).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

For this problem, we have that:

[tex]n = 94, \pi = \frac{27}{94} = 0.2872[/tex]

98% confidence level

So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2872 - 2.327\sqrt{\frac{0.2872*0.7128}{94}} = 0.1786[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2872 + 2.327\sqrt{\frac{0.2872*0.7128}{94}} = 0.3958[/tex]

The 98% confidence interval for the population proportion of purchases paid with a major credit card is (0.1786, 0.3958).
