Find the measure of the missing angle

Answer:

  (d)  No. He multiplied with the reciprocal of the dividend instead of with the reciprocal of the divisor.

Step-by-step explanation:

The problem should have been written ...

  [tex]\dfrac{7}{20}\div\dfrac{2}{5}=\dfrac{7}{20}\times\dfrac{5}{2}\qquad\text{the reciprocal of the divisor is used}[/tex]

Instead, Ben wrote it as ...

  [tex]=\dfrac{20}{7}\times\dfrac{2}{5}\qquad\text{the reciprocal of the dividend is erroneously used}[/tex]

Answer:

m + 30 ; $36

Step-by-step explanation:

Given that:

Total fruits needed = 15

Fruits needed :

Apple (m) ; cost = $3 per piece

Oranges (o) ; cost = $2 per piece

Amount spent on fruits :

[(cost of apple * number of apples) + (cost of orange *(total fruits - number of apples)]

3m + 2(15 - m)

3m + 30 - 2m

3m - 2m + 30

m + 30

Amount spent if 6 apples is purchased :

m = 6

m + 30

6 + 30 = $36

Step-by-step explanation:

The provided arithmetic sequence adds up to 60.

The difference between every two successive terms in an arithmetic series is always the same. The number "a" is the first term, and "d" is the common difference between the sequence. The nth term of an arithmetic sequence is given by. aₙ = a + (n – 1)d

Given an arithmetic sequence 12, 14,16,18

The general formula for the Sum of arithmetic sequence:

Sn = n/2 [2a+(n−1)d]

where: n = the number of terms to be added.

a = the first term in the sequence.

d = the constant value between terms.

In our case,

a = 12

n = 4

and d = 14 - 12 = 2

thus

Sum = 4/2(2*12 + (4- 1 )2)

Sum = 2( 24 + 6)

Sum = 60

therefore, the Sum of the given Arithmetic sequence is 60.

The solution of the expression 4¹/₃ x 6 will be 26.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is 4¹/₃ x 6. The expression of multiplication will be solved as below,

E =  4¹/₃ x 6

E = ( 13 / 3 0 x 6

E = 13 x 2

Answer:

Sometimes

Step-by-step explanation:

To answer this question, I'll make use of the following illustrations:

GCF of 4 and 10

[tex]4 = 1 * 2 * 2[/tex]

[tex]10 = 1 * 2 * 5[/tex]

Hence:

The GCF is

[tex]GCF = 1 * 2[/tex]

[tex]GCF = 2[/tex]

GCF of 5 and 10

[tex]5 = 1 * 5[/tex]

[tex]10 = 1 * 2 * 5[/tex]

[tex]GCF = 1 * 5[/tex]

[tex]GCF = 5[/tex]

In the first scenario, the GCF is lesser than the smallest number.

In the second, the GCF is equal to the smaller number.

Hence:

Answer:

P [ β / Def]  = 0,6521     or      65,21 %

Step-by-step explanation:

Tree diagram:

0,20 (α)       Defective  0,02

0,50 (β)       defective   0,06

0,30 (γ)       defective    0,04

According to Baye´s Theorem

P [ A/B]  = P[A] * P [ B/A] / P[B]

if we call

β = A   and  Defective = B       then  P[β] = P[A]  and P[Defective] = P[B]

we get :

P [ β / Def]  = P[β] * P [ def./β] / P[def]

Then

P[β] = 0,5

P[def/β] = 0,06

P [Defective] = 0,02* 0,2 + 0,06*0,5 + 0,04*0,3

P [Defective] = 0,004 + 0,03 + 0,012

P [Defective] = 0,046

P [ β / Def]  = 0,5 * 0,06 / 0,046

P [ β / Def]  = 0,6521     or      65,21 %

The y intercept is (0,2) and the x intercept is (5,0)

Step-by-step explanation:

Find the y-intercept by letting x = 0

2(0) + 5y = 10

5y = 10

y = 2 Therefore, the y-intercept is (0, 2)

Find the x-intercept by letting y = 0

2x + 5(0) = 10

2x = 10

x = 5 Therefore, the x-intercept is (5, 0)

Answer:

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

Step-by-step explanation:

Given

Equation:

[tex]y = \frac{1}{3}x + 4[/tex]

[tex]Point: (-3,1)[/tex]

Required

Determine the equation of the point parallel to the given equation

First, we need to determine the slope of: [tex]y = \frac{1}{3}x + 4[/tex] using

[tex]y = mx + b[/tex]

Where m represents slope.

By comparison

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

The equation of the point is calculated as thus:

[tex]y - y_1 = m(x - x_1)[/tex]

Where [tex](x_1,y_1) = (-3,1)[/tex]

So, we have:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 1 = \frac{1}{3}(x - (-3))[/tex]

[tex]y - 1 = \frac{1}{3}(x +3)[/tex]

[tex]y - 1 = \frac{1}{3}x +1[/tex]

Solve for y

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

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

The answer is ±3[tex]\sqrt{3\\}[/tex]

First, you should make one side of the quadratic 0. You can do this by subtracting 17 from both sides, making the equation

2/3x^2 - 18 = 0

To make everything an integer, you can multiply both sides by 3/2, making the equation

x^2 - 27 = 0

By adding 27 to both sides, you get

x^2 = 27

Now you are practically done! By taking the square root of both sides, you get

x = ±3[tex]\sqrt{3\\}[/tex]

Answer:

Anthony paid for 7 days of parking.

Step-by-step explanation:

From the information given, the cost of parking a motor home in a state park would be equal to the one time fee plus the result of multiplying the daily rate for the number of days:

c=180+55x, where c is the cost of parking the motor home and x is the number of days.

Now, you can replace c with 565 that is the amount Anthony prepaid and you can solve for x to be able to find the number of days he paid for:

565=180+55x

565-180=55x

385=55x

x=385/55

x=7

According to this, Anthony paid for 7 days of parking.
