help loll i need an 100

Answer:

2800 is a good estimate

Step-by-step explanation:

Rounding to the nearest hundred

674 = 700

692 = 700

724 = 700

739 = 700

700+700+700+700 = 2800

Answer:

$4.52 is what they'd need to pay.

Step-by-step explanation:

0.25 x 7 = 1.75

7 - 1.75 = 5.25

100 - 14 = 86

0.86 x 5.25

= 4.515 and round to the nearest hundredth

Answer:

88 markers long just take 22 and divide it by .25

A = L*w

324 = L*w

324/w = L

P = 2*( L + w)

= 2 * ( 324/w + w)

= 648/w + 2w

= (648 + 2w^2)/w

Answer:

E. 214

Step-by-step explanation:

Since the other angles of the triangle are congruent, and separated creates 2 right triangles, this means that segment (because i cant put the actual names for some reason) A to F and segment F to B are equal

8x - 37 = 5x + 17

3x = 54

x = 18

Now substitute to check

8(18) - 37 = 5(18) + 17

107 = 107

So if this is true, to find the segment A to B, just add segments A to F and F to B together

107 + 107 = 214

The length of segment AB is 214

Answer:

l.y=4

m.y=-2x+4

n.1x-1

p.x=-4

Step-by-step explanation:

The equations of the lines given in the graph will be,

y = x - 1

y = -2x +4

y = 4

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

For line one the points are:-

( 3,2 ) and ( 1,0)

Slope = ( 0 -2 ) / ( 0 - 3 )

Slope = 1

The equation will be,

y = x + c

0 = 1 + c

c = -1

For line two the points are:-

(0,4) and (2,0),

Slope = ( 0 - 4 ) / ( 2 - 0 )

Slope = -2

The y-intercept will be,

y = mx +c

y = -2x + c

c= 4

The equation can be written as:-

y = -2x +4

The equation of the line parallel to x-axis is,

y = 4

Answer:

46

240

Step-by-step explanation:

Substitute the given values for the variables, and evaluate the expressions.

1.

n = -5; m = 4

2n² - m = 2(-5)² - 4 = 2(25) - 4 = 50 - 4 = 46

2.

H = 60; Q = 40; V = 10

HQV/100 = (60)(40)(10)/100 = 6(4)(10) = 240

Answer:

Step-by-step explanation:

1) Put n = -5 and m = 4 into the equation, you'll then have;

2(-5)²-4

2(25)-4

50-4=46

2) Put H=60, Q=40 and V=10 into the equation, then you'll have that;

Answer:

1 2/3, and -1 2/3

Step-by-step explanation:

Im wondering how old you are, and since you seem young just based off the math you're asked to do, please listen to the explanation and teach yourself this. This skill in particular is SOOO important to the rest of the math world. So since your number line is already divided into thirds, there are two ways you could find your answer. One, you can count 5 thirds away from zero, or two, you could simplify 5/3 from an improper fraction to a mixed number (1 2/3) and find your spot from there. "and the opposite" means not only the point 5/3 Away from zero on the Right, but also 5/3 away from zero on the Left. start from zero again and count the same amount away but in the opposite direction. With negatives it can help to think of how all numbers are just descriptions of how far left or right a number is from zero. i hope this helped lol, negatives are a confusing batch, but they're so so important to math as a whole.

Step-by-step explanation:

Answer:

y - 9 = m(x + 3)

Step-by-step explanation:

Given a line whose slope is m, the slope of a new line that is perpendicular to the given line is the negative reciprocal of m:  -1/m

Given y = 2x + 8, we see that the slope is 2 and figure that the negative reciprocal of that is -1/2.  This is the slope of the desired perpendicular line.

We can write the equation of this perpendicular line most easily by using the point-slope form y - k = m(x - h), where (h, k) represents the point:

y - 9 = m(x + 3)

Answer:

21

Step-by-step explanation:

The average rate of change of function f(x) from x = a to x = b is

[tex] \dfrac{f(b) - f(a)}{b - a} [/tex]

Here we have

a = -1

b = 2

f(a) = f(-1) = 1

f(b) = f(2) = 64

[tex] \dfrac{f(b) - f(a)}{b - a} = [/tex]

[tex] = \dfrac{f(2) - f(-1)}{2 - (-1)} = [/tex]

[tex] = \dfrac{64 - 1}{2 + 1} [/tex]

[tex] = \dfrac{63}{3} [/tex]

Step-by-step explanation:

Solve this using ratio

---------

15 rounds / 25 minutes

---------

Find out how many rounds per minutes: 25/15

1 round / (5/3) minutes

--------------

48 divided by (5/3) to get rounds now.

---> (48*3)/5 ---> 144/5 ---> 28.8

28.8 rounds. So she only completed 28 full rounds as she didn't manage to complete 29 just yet.

Answer:

y < 5

Step-by-step explanation:

Subtract 22 from both sides.

7y < 5y + 12 - 2

7y < 5y + 12 − 2

2 Simplify  5y + 12 - 25y + 12 − 2  to  5y + 105y + 10.

7y < 5y + 10

7y < 5y + 10

3 Subtract 5y5y from both sides.

7y - 5y < 10

4 Simplify  7y - 5y7y − 5y  to  2y.

2y<10

Divide both sides by 22.

y < 10/2

Then Simplify 10/2 to 5

y < 5

Answer: 150 m, 5.305*10^-5 kW/m^2, No

Step-by-step explanation:

See attachment, hope this helps

Using the radiation intensity formula we will have to:

a) [tex]150 m[/tex]

b) [tex]5.305*10^{-5} kW/m^2[/tex]

c)No

From the data informed, we have:

[tex]h=150m\\P=40KW[/tex]

Using the given formula and performing some mathematical operations:

[tex]I=\frac{12Psin^2(\theta)}{32(\pi)r^2} \\I= \frac{12(40)(R/r)^2}{32(\pi)r^2} \\= \frac{15R^2}{r^2\pi } \\= \frac{15R^2}{(R^2+150^2)^2\pi} \\[/tex]

deriving the given equation, we will have:

[tex]=\frac{(R^2+150^2)^22R-R^2(2(R^2+150^2))2R}{(R^2+150^2)^2}[/tex]

So from this equation we have that the answer of the letter A corresponds:

[tex]R=150[/tex]

For letter B we will have to develop this equation:

[tex]I= 5.30X10^{-5}[/tex]

As for the letter C, when converting the value found, it should give 200 microwatts, which is false.

Answer:

c) difficult

Step-by-step explanation:

1) w = 14/3

Steps:

1) Multiply the numbers

5w - 8/3 = 4w + 2

2) Add 8/3 to both sides of the equation

5w - 8/3 + 8/3  = 4w + 2 + 8/3

3) Simplify

A. Add the numbers

5w = 4w + 2 + 8/3

B. Add the numbers

5w = 4w + 14/3

4) Subtract 4w  from both sides of the equation

5w - 4w = 4w +14/3 - 4w

5) Simplify

A. Combine like terms

1w = 4w + 14/3 - 4w

B. Multiply by 1

w = 4w + 14/3 - 4w

C. Combine like terms

w = 14/3
