B.5 + 3 = 8

C.3+ 5 = 8

D. 5x 3 = 3 x 5

I need to know ASAP pls

Answer:

1. 34

2. 56

3. 112

4. 68

Step-by-step explanation:

For the first one, the angle measuring 112 is a vertical angle to angle 9 so angle 9 is also 112. So 180-112 (180 because the measure of every triangle is 180.) is 68. Then you divide 68 by 2 and get 34 because the angles 1 and 8 measure the same.

For the second one, you would first find the measure of angle 10 by subtracting 180-112 again and getting 68 (the measure of a flat line is 180.) Then you would get 112 for the remaining angles and divide that by two because once again, the two angles are the same measure. So 112 divided by 2 is 56.

For the third one, I already stated that the measure of angle 9 is 112.

And finally, for the fourth one, I also previously stated that the measure of angle 10 is 68.

The decimal value of the number 2(5/8) will be 2.625.

A mixed fraction is one that is represented by both its quotient and remainder. A mixed fraction is, for instance, 2 1/3, where 2 is the quotient and 1 is the remainder.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given mixed fraction is 2( 5/8). The fraction in the decimal form will be written as below:-

2( 5/8) = ( 21 / 8 )

2( 5/8) =  2.625

Therefore, the decimal value of the number 2(5/8) will be 2.625.

Answer: -209

Step-by-step explanation:

Formula for arithmetic progression

= a + (n - 1)d

Since a10 = 1 and d = -6

a10 = a + 9d

a + 9(-6) = 1

a - 54 = 1

a = 1 + 54

a = 55

Therefore, 45th term = a + (n - 1)d

= a + (45 - 1)d

= a + 44d

= 55 + 44(-6)

= 55 - 264

= -209

Answer:

0

Step-by-step explanation:

The first step is to locate the median.

The median is the middle value of the numbers arranged in ascending order. If there is no exact middle value then it is the average of the numbers either side of the middle.

- 2,  0,  1,  7,  9,  10 ← ascending order

              ↑ middle

median = [tex]\frac{1+7}{2}[/tex] = [tex]\frac{8}{2}[/tex] = 4

The lower quartile Q₁ is the middle value of the numbers to the left of the median, that is

- 2,  0,  1

       ↑

lower quartile Q₁ = 0

Answer:

Cost of 1 hamburger = $1.3

Step-by-step explanation:

Assume;

Cost of 1 hamburger = a

Cost of 1 French fries = b

On first trip

3a + 4b = 7.10......eq1

On second trip

2a + b = 3.40....eq2

From eq2 x 4

8a + 4b = 13.6....eq3

From eq3 - eq1

5a = 6.5

a = 1.3

Cost of 1 hamburger = $1.3

The cost of a hamburger and an order of French pies is $1.3 and $0.8 respectively.

let

cost of hamburger = x

cost of French pies = y

The equation:

3x + 4y = 7.10 (1)

3x + 4y = 7.10 (1)2x + y = 3.40 (2)

multiply (2) by 4

8x + 4y = 13.6 (3)

3x + 4y = 7.10 (1)

subtract (3) from (1)

8x - 3x = 13.6 - 7.10

5x = 6.5

x = 6.5 / 5

x = 1.3

substitute x = 1.3 into (2)

2x + y = 3.40 (2)

2(1.3) + y = 3.40

2.6 + y = 3.40

y = 3.40 - 2.6

y = 0.8

Therefore, cost of a hamburger and an order of French pies is $1.3 and $0.8 respectively.

Step-by-step explanation:

Length of side AB = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Length of BC = [tex]\sqrt{(-4+11)^2+(-2-2)^2}[/tex]

                      = [tex]\sqrt{49+16}[/tex]

Since, AC = BC, ΔABC will be an isosceles triangle.

Answer:

3.24!

Step-by-step explanation:

Option c is correct, 4.05 multiplied by 0.8 is equal to 3.24.

To calculate 4.05 multiplied by 0.8, you multiply the two numbers together.

First, you can ignore the decimal points and multiply 405 by 8, which equals 3,240.

Next, you count the total number of decimal places in the original numbers.

The decimal point is present in both 4.05 and 0.8, so there are two decimal places in total.

To get the final result, you need to place the decimal point in the product so that it has two decimal places.

Starting from the right side of the product, you place the decimal point two places to the left, resulting in 3.24.

Therefore, 4.05 multiplied by 0.8 is equal to 3.24.

Answer:

[tex]y = 1500(0.024)^t[/tex]

Step-by-step explanation:

Given

[tex]a = 1500km[/tex] -- initial area

[tex]b = 2.4\%[/tex] -- rate

[tex]t = time[/tex] --- (years)

Required

Represent as an exponential function

An exponential function has the form:

[tex]y = ab^t[/tex]

Where

[tex]a = initial\ value[/tex]

[tex]b = rate[/tex] and [tex]b \ne 1[/tex]

[tex]t= time[/tex]

Substitute values for a and b, we have:

[tex]y = 1500 * (2.4\%)^t[/tex]

Convert percentage to decimal

[tex]y = 1500 * (0.024)^t[/tex]

[tex]y = 1500(0.024)^t[/tex]

Hence, the exponential function that represents the scenario is: [tex]y = 1500(0.024)^t[/tex]
