Step-by-step explanation:

26.

First convert each mixed number to an improper fraction:

-12 2/3 = -38/3

- 1 1/9 = -10/9

-38/3 = -10/9 * y

y = -38/3 / -10/9

y = -38/3 * -9/10

  = -38 * -3 / 10

  = 114/10

  = 57/5

  = 11 2/5.

27,

1 5/7 = 1 13/14 a

12/7 = 27/14 a

a = 12/7 / 27/14

  =  12/7 * 14/27

  = 24/27

  = 8/9.

Answer:

y=4x-9

Step-by-step explanation:

The equation of a line is typically written in slope-intercept form, which is y=mx+b. Here's what the variables mean:

y=the y-coordinate

m=the slope

x=the x-coordinate

b=the y-intercept (the point on the line that intercepts the y-axis)

The only values that we have to calculate to find the equation are the slope of the line and the y-intercept. Let's start off by finding the slope.

To find the slope of a line, we would need to find 2 points that fall on the line, [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] and plug them into the expression [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Let's use the points (1, -5) and (3, 3).

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\frac{3-(-5)}{3-1}[/tex]

[tex]=\frac{3+5}{3-1}\\= \frac{8}{2}\\= 4[/tex]

Therefore, the slope of the line is 4.

To find the y-intercept, all we need to do is look at which point the line crosses the y-axis, and that point is -9.

Finally, we plug the slope and the y-axis into the equation y=mx+b as m and b.

y=mx+b

y=4x-9

Answer:

1. Answer is 160 m

2. Answer is 1500 m²

Step-by-step explanation:

perimeter = 2(l+b)

which implies 2( 28.3 + 53.7) m = 160 m

Area is length× breadth

which implies 28.3× 53.7 = 1500 m²

Answer:

2.5 hours

Step-by-step explanation:

Let t = time in hours for reach friend's house

(t-1.5) = time for friend to drive her home

:

Both trips are the same distance, Write a distance equation from this fact:

Distance = speed * time

Drive distance = Bike distance

Equation-

step1)   25 (t-1.5) = 10t          (here u multiply 25 by t and 25 by 1.5)

step2)  25t - 37.5 = 10t        (move 37.5)          

step3)  25t - 10t = +37.5      (subtract 25t from 10t)

step4)  15t = 37.5                 (divide 37.5 by 15)

step5)  t = 2.5                     (time it took Luke to reach his aunt's house)

Answer:

16

Step-by-step explanation:

To find 80% of 20, multiply .80 x 20

.80×20 = 16

This is how you multiply percentages--put the decimal point 2 places to the left, then multiply.  In this case, you're looking at 80%, so move the decimal point two places to the left

80.0 becomes .80

Then multiply that by the number you're trying to find the percentage of

Answer:

34

Step-by-step explanation:

plug 7 into 4x

plug 2 into 3z

do the math so...

4 X 7 =28

2 X 3 = 6

add 28 + 6 = 34

According to the given statement ,

a debt to double at 42% p.a. compound interest will take approx 2 years.

Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.

Compound interest is calculated on the initial principal of a deposit or loan, which also takes into account all of the accumulated interest from prior periods.

The yearly interest rate is raised to the number of compound periods minus one, and the starting principal amount is multiplied by both of these factors.

According to the given data,

Let principal = P

Time = t

Rate == 42%

Amount = A

Given Condition is A = 2P

=> P[1+ r/100]ⁿ =  2P

=> P [1 + 42/100 ]ⁿ = 2P

=> (1.42)ⁿ=2

n= log₁.₄₂ 2 =0.301/0.152

n=1.980≅2

Hence , the time it take for a debt to double at 42% p.a. compound interest is approx 2 years.

Answer:

Frequency is 3

Step-by-step explanation:

A sine function repeats in periods and it's frequency can be gotten using:

y(x) = sin(2πfx) where f is the frequency

We are given x = 4sin(6πx) + 1

This can be rewritten as: x = 4sin(3*2πx) + 1

Therefore, our f = 3.

Hence frequency of the sine function is 3.

Probability of sum greater than 5 event is reduces to 13/18 .

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

probability of getting number whose sum is divisible by 2 and 3 both is 6/36 which reduces to 1/6 .

The sample space of rolling two dice has 36 possible outcomes.  Remember that the "sample space" is a set which contains all possible outcomes.   (1,1)(2,1)(3,1)(4,1)(5,1)(6,1)(1,2)(2,2)(3,2)(4,2)(5,2)(6,2)(1,3)(2,3)(3,3)(4,3)(5,3)(6,3)(1,4)(2,4)(3,4)(4,4)(5,4)(6,4)(1,5)(2,5)(3,5)(4,5)(5,5)(6,5)(1,6)(2,6)(3,6)(4,6)(5,6)(6,6)

The probability of the sum is greater than 5 event is 26/36 which reduces to 13/18 .And the probability of getting number whose sum is divisible by 2 and 3 both is 6/36.
