Since A and B are opposite angles on parallel lines, we know that they sum up to 180:

[tex](8x + 74) + (2x + 56) = 180[/tex]

[tex]10x + 130 = 180[/tex]

[tex]10x = 50[/tex]

[tex]x = 5[/tex]

We can plug this into the equation for angle B to get the actual angle:

[tex]B = 2x + 56[/tex]

[tex]B = 2(5) + 56[/tex]

[tex]B = 10 + 56[/tex]

[tex]B = 66[/tex]

Answer:0.5, 0.5

Step-by-step explanation:

Given

[tex]P(A\cap B)=0.25[/tex]

Also, A and B are independent events. So, we can write that

[tex]P(A\cap B)=P(A)\times P(B)[/tex]

[tex]0.25=P(A)\times P(B)[/tex]

So, the two most possible value of [tex]P(A)\ \text{and}\ P(B)[/tex] are [tex]0.5\ \text{and}\ 0.5[/tex]

The area of a square is x²

This means it is  x² = 64cm²

x= 8cm <------ One side

Since it is a square, all sides are the same length.

8*4 = 32cm

Side of the square: 8 cm

Perimeter: 32cm

Answer:

[tex]3 \sqrt{7} [/tex]

Step-by-step explanation:

[tex] \sqrt{3 \times 3 \times 7} [/tex]

2) Group the same prime factors into pairs.

[tex] \sqrt{(3 \times 3) \times 7} [/tex]

3) Rewrite each pair in exponent form.

[tex] \sqrt{ {3}^{2} \times 7 } [/tex]

3) Use this rule

[tex] \sqrt{ {x}^{2} } = x[/tex]

Step-by-step explanation:

Center = (3,-4)   Radius = 5

This equation is already in standard form so you just have to pull out the h and k values which in this case are 3&4, just remember to flip the signs so it'll be 3&-4. Just square the right side and that is the radius, in this case 5

Answer:

2.05hrs

Step-by-step explanation:

Given he total cost c(x) of hiring a dump truck and an operator is described by the function c(x)=300+31x-3.90x^2 , where x is the number of hours worked. If c(x)=$220, then;

220  = 300+31x-3.90x^2

300+31x-3.90x^2 - 220 = 0

3.90x^2 + 31x - 80 = 0

x = -31±√31²-4(-80)(3.9)/2(3.9)

x = -31±√961+1.248/7.8

x = -31±47/7.8

x = -31+47/7.8

x = 16/7.8

x = 2.05

hence the number of working hours is 2.05hrs

Answer:

$118.75

Step-by-step explanation:

To find the markdown, subtract the amount from the original amount.$171.50 - $145.12 is $26.38.Therefore, the markdown is $26.38 from the original amount.Now we have to subtract the markdown from the original price.$171.50 - $145.12 is 118.75.This is your final answer.

If the original selling price was ​$171.50 The sale price was ​$145.12, and the greatest markdown possible will be $26.38.

It represents the ratio of two numbers expressed as a decimal fraction of a hundred parts. It is a statistic for contrasting two sets of data, and it is denoted as a percentage using the symbol %.

It is given that the original selling price and sale price were ​$171.50  ​and $145.12 respectively.

Subtract the amount from the original amount to get the markdown. We must now deduct the reduction from the original price in order to determine the largest markdown.

=$171.50 - $145.12

=$26.38

The markdown is $26.38 from the original amount.

Thus, as the purchase price was $171.50 at first, The maximum markdown will be $118.75, whereas the selling price was $145.12.

Answer:

Mrs. Stewart paid $86.25 for all the books.

Step-by-step explanation:

With the information provided, you have to add the result of multiplying the nine books for its price plus the remaining books for the price per book. To find the number of the remaining books you can substract the nine books from the total amount Mrs. Stewart purchased.

Cost=(9*4.95)+((15-9)*6.95)

Cost=44.55+41.7

Cost=86.25

According to this, the answer is that Mrs. Stewart paid $86.25 for all the books.

Answer:

  4 kg : 12 kg : 20 kg

Step-by-step explanation:

The total number of "ratio units" is 1+3+5 = 9, so each of them represents ...

  (36 kg)/9 = 4 kg

Multiplying the given ratio by 4 kg will show the appropriate division:

  1(4 kg) : 3(4 kg) : 5(4 kg) = 4 kg : 12 kg : 20 kg

The smallest number is x = 11/3. The smallest number in the given ratio of 1:2:3:4:5 whose mean is 11 is 11/3.

Given that the mean of 5 numbers is 11. The numbers are in the ratio 1:2:3:4:5. We need to find the smallest number. We can start solving the problem by following these steps:

Step 1: Let us assume the smallest number to be x.

Step 2: According to the question, the numbers are in the ratio 1:2:3:4:5. Hence, the other four numbers can be written as 2x, 3x, 4x, and 5x.

Step 3: The mean of these 5 numbers is given as 11.

Therefore, we can write:(x + 2x + 3x + 4x + 5x)/5 = 11.

Step 4: Simplifying the above equation, we get:15x/5 = 11x = 11/3.

Step 5: Therefore, the smallest number is x = 11/3.

The smallest number in the given ratio of 1:2:3:4:5 whose mean is 11 is 11/3.

Answer:

r=2,n=7

Step-by-step explanation:

The formula for the sum of the nth term of a Geometric Progression is given as:

Sn = a(1-r^n)/(1-r)

Where n = Number of terms

r = Common ratio

From the above question, we are told that:

The sum of the 1st nth term gp is 127.

Hence:

127 = 1(1-r^n)/(1-r)

We are also told that:

The sum of the reciprocal is 127/64

This means the inverse, the formula is given as:

Sn = 1/a(1-r^n)/(1-r)

127/64 = 1(1-1/r^n)/(1-1/r)

= r^(1-n)(1-r^n)/(1-r)

Solving the above, we obtain:

r^(n-1) = 64

r^(n-1) = 2⁶

Hence:

r = 2

Solving for n

n - 1 = 6

n = 6 + 1

n = 7

Therefore:

r=2,n=7
