We can deduce here that for a height of 145 cm, a likely interval of ages could be: 12 ≤ age ≤ 15

In mathematics, an inequality is a mathematical statement that expresses a relationship between two quantities, indicating that one quantity is greater than or less than another. It represents a comparison or a difference in values.

For a height of 145 cm, a likely interval of ages could be:

12 ≤ age ≤ 15

This range assumes that the child's height falls within the average height range for boys aged 12 to 15 years. However, it's important to consider that individual variations and growth patterns can influence a child's height, so this interval should be interpreted with caution.

You're going to take 40,000 multiplied by 7.2 which gives you the interest for one year. Multiply that by 5 to get through interest for 5 years.

The amount of interest that she gained after the maturity of the plan will be ₱14,400.

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

I = (PRT)/100

Where I is the interest, P is the principal, R is the rate of interest, and T is the time.

Ms. Dorothy deposited ₱40,000 in a bank new plan paying 7.2% simple interest per annum if withdrawn after 5 years, otherwise, the plan will not apply.

Then the amount of interest that she gained after the maturity of the plan will be

I = (40,000 x 7.2 x 5) / 100

I = 400 x 7.2 x 5

I = ₱14,400

The amount of interest that she gained after the maturity of the plan will be ₱14,400.

Step-by-step explanation:

Answer:

slope = 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + y = 3 ( subtract x from both sides )

y = - x + 3 ← in slope- intercept form

with slope m = - 1

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-1}[/tex] = 1

The slope of the given line is 4.

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Given that, a line passing through points (3, 9) and (1, 1) we need to find the slope of the line,

Slope = y₂ - y₁ / x₂ - x₁

So,

Slope = 9-1 / 3-1 = 8/2 = 4

Hence, the slope of the given line is 4.

2146/45= 47 31/45. round to 48 questions a week.

I would choose the first one. Even though the 2000 is an underestimate, the 50 weeks is overestimate , when divided it comes out to 50 questions a week which is closer to the 48 it actually is. I'd rather write too many questions then not enough.

Answer:

P = 25m - 15

Step-by-step explanation:

Kindly find attached the table of values for your reference.

Step one:

given data

let us set up the coordinate using the value of p and m

p=35

p1=10

m=2

m1=1Tthe cordinate is (p1,p),(m1,m)= (y1,y),(x1,x)

(1,10), (2, 35)

the slop is given as, slope m = (p- p1)/(m - m1)

m=(35-10)/(2-1)

m = 25

from the equation of line y=mx+c

y = 25x + c

10 = 25(1) + bc

c= -15

y = 25x - 15

in term of m and p we have  P = 25m - 15

Answer:

x is eighteen

y is fifty four

Answer:

x= 18 degrees and y=54 degrees

Step-by-step explanation:

Look at the top of the line AB. You can see that

3x+y+72=180

Now, look at the left side of the line CD. You can see that

y+90+2x=180

Hence, you have 2 equations in 2 unknows, which are possible to solve.

In resume, the 2 equations are:

3x+y+72=180

2x+y+90=180

By substracting the second equation to the first one, it yields

x-18=0

which implies x=18.

Now, we can susbstitute this value on the fist equation:

3(18)+y+72=180

54+y+72=180

y+126=180

y=180-126

y=54

We can corroborate these result in the second equation:

2(18)+54+90=

36+54+90=

90+90=

180.
