Find the distance between the points (-4, -5) and (3, -1).

Answer:

Kindly check explanation

Step-by-step explanation:

When performing addition and subtraction of decimals, it is important to arrange the numbers being added or subtracted such that the decimal points are in line. This is particularly important so that the place value of the numbers are in accord.

To simplify, when then decimals are in line, then the tenth value of the first number will be added to the tenth value of the second. Without this arrangement, one might be adding the hundredth placed value to the tenth or unit value which is mathematically incorrect and will yield a wrong result.

For instance :

6.32 - 0.5

Here, when the decimal point of each number is in line, the tenth placed value of the first number (3) matches the tenth placed number of the second number (5) and all others also fall in place automatically.

____6.32

- ___0.5

___ 5.82

Step-by-step explanation:

The sum of ages is 8+9+10 = 27, so each year of age is rewarded by ...

  216/27 = 8 . . . Rs

Then age 8 gets 8(Rs. 8) = Rs. 64

  age 9 gets 9(Rs. 8) = Rs. 72

  age 10 gets 10(Rs. 8) = Rs. 80

Answer:

0

Step-by-step explanation:

because we can't multiply anything by 0.

is like saying 0×0×0×0=0

2. Amount of soil provided.

In order to give different pH values of the soil, the amount of soil can directly affect this independent variable.

Answer: 3/10

Step-by-step explanation: 1/2 x 3/10 = 3/20 and we can’t simplify that.

Answer:

The simplest form of 1/2 x 3/10 would be 3/20

If you need it in decimal form it's: 0.15

Step-by-step explanation:

Answer:

k = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The equation of proportionality is

y = kx ← k is the constant of proportionality

To find k use any coordinate point lying on the graph

Using (12, 6 ), then

6 = 12k ( divide both sides by 12 )

k = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

Here are the steps I think you probably will go through.

1. Draw a line that is longer than the segment but shorter than the width of the page.

1a. Make sure this line is  at least 1/2 inch from the left hand side.  

2. Use a compass to measure the length of the original segment. Never use a ruler. Rulers do not exist in pure geometry.

3. Measure out the distance on the line you just drew with the compass. One end is on the left hand edge and the other end (the pencil end) is marking the segment so it is the same length as the compass. You are done.

The key step either two or three.

Answer: Step Two

Draw a line that is longer than the segment but not wider than the page's width. This line should be at least 1/2 inch away from the left-hand side. After that, measure the length of the original segment with a compass. Following that step, measure the distance along the compass line. (One end is on the left edge, while the other (the pencil end) is used to mark the section so that it is the same length as the compass) Step two is the most important step in the process of copying a line segment to ensure that the new line segment is the same length as the original.

I took the test

Answer:

9.33%

Step-by-step explanation:

Step one:

given

Principal= $10,000

Final amount = $150,000

time = 50-21= 29 years

Required

The rate

Step two:

to solve for the rate we can apply the formula for rate as

r = ln(A/P) /t

r= ln(150000/10000)/29

r= ln(15)/29

r=2.7080502011/29

r=0.0933

r= 0.0933*100

r= 9.33%

Step-by-step explanation:

If your teacher asks why it's so specific tell them you used desmos <3

Step-by-step explanation:

w(2w - 30) = 5400

2w²- 30w = 5400

2w² - 30w - 5400 = 0

(w - 60 ) ( w + 45 ) = 0

w= 60 w= - 45

only take the positive value

therefore w = 60

Answer:

Seven candy bars.

Explanation:

Suppose the number of candy bars purchased is x

The questions say he bought A magazine, means one magazine

the equation is:

4x + 5 = 33

4x = 33 – 5

4x = 28

x = 7

Kim bought 7 candy bars.

Hope this helps! :)

Answer:

1) I just simply added the numerators because the denominators of both fractions are equal. As the denominators are same , I simply wrote 6 by taking the L.C.M of both denominators.

4)

[tex] \frac{5x - 3}{6} + \frac{x - 9}{6} [/tex]

[tex] = > \frac{5x - 3 + x - 9}{6} [/tex]

[tex] = > \frac{6x - 12}{6} [/tex]

Taking 6 common from numerator,

[tex] = > \frac{6(x - 2)}{6} [/tex]

Cancelling 6 from both numerator & denominator,

[tex] = > x - 2[/tex]

Answer:

Step-by-step explanation:

256 = 16×16=4×4×4×4 = 4^4

X^4-4^4 = (x^2)^2 - (4^2)^2

Using algebraic identity a^2-b^2 = (a+b)(a-b)

We get (x^2+4^2)(x^2-4^2)

(x^2+4^2)(x+2)(x-2)

Answer:

C.) 4 sqrt2

Step-by-step explanation:

ON=MN

therefore you can use pythagereum theorum here in a right triangle

as the hypotnuese is 8 you know that ON and MN is equal to the sqrt of 32 each. As A^2+ B^2=C^2

C=8 so C^2= 64 therefore,

A^2+ B^2=64 therefore,

A^2= 32 and B^2=32

you take the sqrt of 32 you get 4sqrt2

Answer:

  a)  E = 6500 -50d

  b)  5000 kWh

  c)  the excess will last only 130 days, not enough for 5 months

Step-by-step explanation:

Given:

  starting excess (E): 6500 kWh

  usage: 50 kWh/day (d)

Find:

  a) E(d)

  b) E(30)

  c) E(150)

Solution:

a) The exces is linearly decreasing with the number of days, so we have ...

  E(d) = 6500 -50d

__

b) After 30 days, the excess remaining is ...

  E(30) = 6500 -50(30) = 5000 . . . . kWh after 30 days

__

c) After 150 days, the excess remaining would be ...

  E(150) = 6500 -50(150) = 6500 -7500 = -1000 . . . . 150 days is beyond the capacity of the system

The supply is not enough to last for 5 months.

Answer: 640 students.

Step-by-step explanation:

given data:

number of student chosen to attend by the mayor = 160

amount this student represents of the total population = [tex]\frac{1}{4}[/tex]

solution:

since [tex]\frac{1}{4}[/tex] was chosen which is 160 this means that [tex]\frac{1}{4} is \geq 160[/tex]

therefore;

[tex]\frac{1}{4} = 160\\[/tex]

multiply both sides by 4

[tex]\frac{1}{4} . 4 = 160 .4\\= 640[/tex]

the least number of students that attend melvins school is 640.

Step-by-step explanation:

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

So

x + x + 50° = 90°

2x = 90° - 50°

2x = 40°

x = 40°/2

x = 20°

x + 50 = 20 + 50 = 70°

Hope it helps :)

Answer:

let 1st angle be x

and another angle be x+50°

two angles are said to be complementary,if the some of their measures is 90°

so,

x+x+50=90

2x+50 =90

2x=90-50

x=40/2

:-x= 20 ....... 1st angle

another angle (x+50)=20+50=70°

Step-by-step explanation:

Let :

Original commute time = x

Commute time due to road construction = 150% of original commute time

Hence, commute time due to road construction :

(150 / 100) * x

0.15x

Hence, the implication of the road construction in progress means that it will now take additional half of the usual time it takes them on a Monday morning.

For instance, an individual whose usu commute time is 10 minutes in the morning will now take :

1.5x = 1.5(10) = 15 minutes commute time on a Monday morning.
