Answer:

m=2

Step-by-step explanation:

use points (2,2) and (6,10)

(find y of slope)10-2=8

(find x of slope)6-2=4

8/4=2

Answer: x=5, y=(5[tex]\sqrt{3}[/tex])/2

Step-by-step explanation:

Using the 30-60-90 triangle rule, we know that the sides follow 1-([tex]\sqrt{3}[/tex]/2)-2. The ratio between the side and the rule is 5/2, meaning that we know that y=(5[tex]\sqrt{3}[/tex])/2 and x=5.

Answer: 22  students made the team this year

Step-by-step explanation:

Given : Total students tried out for the team = 40

After a week , 40% of students made the team, students made the team = 40% of 40

= 0.40 x 40

= 16

Remaining students  = 40 - 16 = 24

After second week, students made the team = 25% of (Remaining students)

= 0.25 x 24

= 6

Total students made the team this year = 16+ 6= 22

Answer:

It will take to Mike 10 days to ride 2x10⁴ meters.

Step-by-step explanation:

We have that Mike rides the bike 2x10³ meters every day, so the distance (D) is:

[tex] D = 2 \cdot 10^{3} \frac{m}{d} [/tex]   (1)

To find the number of days that will take Mike to ride a distance of 2x10⁴ meters, we need to find "t" in the following reaction:

[tex] 2 \cdot 10^{4} m = 2 \cdot 10^{3} \frac{m}{d}*t [/tex]  

[tex] t = \frac{2 \cdot 10^{4} m}{2 \cdot 10^{3} \frac{m}{d}} = 10 days [/tex]

Therefore, it will take to Mike 10 days to ride 2x10⁴ meters.

I hope it helps you!              

Answer: It will take 16 years to have a total of $15,000.

Step-by-step explanation:

Given : Principal value = $ 7,890

Rate of interest = 5.65 % = 0.0565

Amount = $ 15000

Interest = Principal x Rate x time

Amount = Principal + Interest

Amount = Principal + Principal x Rate x time

Amount = Principal ( 1 +  Rate x time )

Substitute values, we get

[tex]15000 = 7890 (1+0.0565 \times t)[/tex]   [ t = time ]

[tex]\dfrac{15000}{7980}=1+0.0565t\\\\\Rightarrow\ 0.0565t = \dfrac{15000}{7980}-1\\\\\Rightarrow\ 0.0565t =\dfrac{117}{133}\\\\\Rightarrow\ 0.0565t =0.87969924812\\\\\Rightarrow\ t=\dfrac{0.87969924812}{0.0565}\\\\\Rightarrow\ t=\dfrac{0.87969924812}{0.0565}\\\\\Rightarrow\ t\approx16\text{ years}[/tex]

Hence, it will take 16 years to have a total of $15,000.

The amount of time taken by Ken to cover 1 mile will be 9.6 minutes.

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

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Ken ran 2 1/6 miles in 20.8 minutes. The amount of time taken by Ken to cover one mile will be calculated as below:-

2 ( 1/6) miles = 20.8 minute

13 / 6 miles = 20.8 minutes

1 miles = ( 6 / 13 ) x 20.8

1 mile = 9.6 minutes

Therefore, the amount of time taken by Ken to cover 1 mile will be 9.6 minutes.

Answer:

49, 96, 400

Step-by-step explanation:

multiplying first and second numbers

The required product that belongs to the last column is given as 49, 69, 400. Option C is correct.

Given that,
A table has shown we have to determine the last column of the table.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

As mentioned in the question the element that lies in the third column is the product of the elements lying in the respective rows.
So,
1  × 49 = 49
2 × 48 = 96
10 × 40 = 400

Thus, the required product that belongs to the last column is given as 49, 69, and 400. Option C is correct.

Answer:

c. 18.25

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

This is a rate of change question, and given the two coordinates, the slope needs to be calculated

Calculate slope (m) with this formula: (y2-y1)/(x2-x1)

the points are (2,41) and (3,59.25)

we can label the points

x1=2

y1=41

x2=3

y2=59.25

now substitute into the equation

m=(59.25-41)/(3-2)

m=18.25/1

m=18.25

So the answer is C

Step-by-step explanation:

Answer:

(See bolded numbers)

Factoring -1 out of negative numbers:

11) (-6) • (3)= (-1 • 6) • 3= -1 • 6 • 3= -18

-6 is the negative number here and factoring out -1 from -6 will give us -1(6). In the second last step, multiply 6 and 3 together then multiply the product by -1.

-1(6 ×3)= -1(18)= -18

12) (-4) • (-8)= (-1 • 4) • (-1 • 8)= 1 • 4 • 8= 32

Multiplying 2 negative numbers will give us a positive number. The 3rd step is 1 as (-1)(-1)= 1.

13) (-9) • (-5)= (-1 • 9) • (-1 • 5)= 1 • 9 • 5= 45

14) (2) • (-8)= 2 • (-1 • 8)= -1 • 2 • 8= -16

Negative numbers are numbers with a negative sign and are numbers less than zero. Factoring -1 out of negative numbers will leave us with the positive number.
