Answer:

60.5

Step-by-step explanation:

320/44=7.27

440/7.27=60.5

Answer: 55 Hours

Step-by-step explanation:

If you take 320 and divide it by 40

you get 8

This means you earn $8 for every hour you work.

Now if you take 440 and divide it by 8, meaning $440 dollars divided by $8

You will get

55, meaning you must work 55 Hours to make $440.

Answer:

-18, -12, 0, 25, 5

0, -12, 5, -18, 25

25, 0, -18, 5, -12

-12, 25, 5, 0, -18

5, -18, 25, -12, 0

Step-by-step explanation:

The only values you need to use here are 0, 5, 25, -12, and -18.

I started with the bottom right box because the far right column only had one empty box. From the set of values I stated above, that column already had each of those numbers except for 0, so 0 would go in the bottom right box.

Another way to think about it is each row or column must have a 5 and a 25 to make 30, and a -12 and a -18 to make -30. Those two numbers cancel each other out to make 0, and then each row/column will include a 0 value which obviously wouldn't effect that balance. So the whole row/column will come out to be 0.

After figuring out that first bottom right box, go to the next row/column with only one empty box left (this happened to be the very bottom row), and use the same strategy to fill in the missing value.

Continue finding the next row/column with only one empty box left and figure out its missing value until you've completed the whole box.

Answer:

0.35

the next one is d(v) = 2.15v^2 / 22.54

Step-by-step explanation:

i just did this assignment. also thanks to the answer above me :)

We have that the value of f, rounded to the nearest hundredth.

f_1=0.02

f_2=0.009

f_3=0.009

From the question we are told that

d(v)= \frac{2.15v^2}{64.4f}

Generally the equation for the f is mathematically given as

f= \frac{2.15v^2}{64.4*d(v)}

Therefore

For v=20 and f=38

f= \frac{2.15(20)^2}{64.4*(38)(20)}

f=0.02

For v=30 and f=86

f=\frac{2.15(30)^2}{64.4*(86)(30)}

f=0.01

For v=40 and f=153

f=\frac{2.15(40)^2}{64.4*(153)(40)}

f=0.009

Answer:

Step-by-step explanation:

A table of values can be generated from a quadratic function by substituting the x-values and calculating the values for f(x). When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.

Answer:

y = 2/3x - 20

Step-by-step explanation:

The fraction in front of the X determines the slope

y = 2/3x - 20 has a slope of 2/3

y = 1/3x + 100 has a slope of 1/3

y = 2/5x + 2 has a slope of 2/5

y = 4/12x has a slope of 4/12

My first tip would be to label your triangles.

If you find our reference angle and go across, that would be our opposite side, so x is the opposite side.

The line with both the reference angle and the right angle would be our adjacent side, so 40 would be the adjecent side.

If you find the right angle and go across, that would be our hypotenuse.

//

In this problem, we are given an angle and the adjacent side and we are looking for the opposite side, so that means that we would be using our tangent ratio.

[tex]tan = \frac{opp}{adj} = \frac{x}{40} [/tex]

[tex] \tan(43) = \frac{x}{40} [/tex]

if the thing you are looking for is on the numerator, we would have to multiply. If the thing you're looking for is in the denominator, you would have to divide.

Since x is on the numerator, we would have to multiply.

[tex]x = 40 \tan(43 ) [/tex]

[tex]x = 37.3006034455[/tex]

[tex]x = 37.30[/tex]

Answer:

After 4 years, Leigh-Anne will have £ 2,813.77 in her account.

Step-by-step explanation:

Given that Leigh-Anne invests £ 2500 for 4 years in a savings account, and she gets 3% per annum compound interest, to determine how much money does Leigh-Anne have at the end of 4 years, the following calculation must be performed:

X = 2,500 x (1 + 0.03 / 1) ^ 4

X = (2,500 x 1,003) ^ 4

X = 2,813.77

Thus, after 4 years, Leigh-Anne will have £ 2,813.77 in her account.

Answer:

y+8 = 2(x-4)

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. Since we know the slope of the first line is -1/2, this means the slope of the line perpendicular to it is 2.

And since we know the coordinated located on the line, we can fill out the formula for poiny-slope form:

y-y1 = m(x-x1)

Answer:

The equation representing the left table is:  

y = 1.5x – 6

The equation representing the right table is:  

y = –4x + 6.1

The solution to the system of equations is:  

(2.2, –2.7)

Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The first table is

x            y

0           -6

1            -4.5

2            -3

3             -1.5

Slope = -4.5+6/1

=1.5

Now let us find y intercept

-6=1.5(0)+b

-6=b

So the equation representing the left table is y=1.5x-6

Now let us find second table

x            y

0           6.1

1             2.1

2           -1.9

3            -5.9

m=2.1-6.1/1=-4

Now y intercept

2.1=-4+b

b=2.1+4

b=6.1

Equation representing the right table is y=-4x+6.1

Now equate two equations

1.5x-6=-4x+6.1

1.5x+4x=6.1+6

5.5x=12.1

x=12.1/5.5

x=2.2

and y=-4(2.2)+6.1

y=-8.8+6.1

y=-2.7

Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

Giveb that :

Area = 40cm²

Height, h = 12 cm

The volume of a prism is the product of it's base area and height, h

Base area = 40cm² ; height = 12cm

Volume = base area * height

Volume = 40cm² * 12cm

Volume = 480cm³

Answer:

Cereal B.

Step-by-step explanation:

To figure out how much it costs per ounce for each cereal, first we need to divide.

Cereal A: $2.25 / 10 = $.225 per ounce

Cereal B: $3.30 / 15 = $.22 per ounce

So, cereal B is less expensive.

Step-by-step explanation:

This is the standard linear equation:

[tex]y=mx+b[/tex]

[tex]m[/tex] represents slope and [tex]b[/tex] represents the y-intercept. In a finished equation, [tex]x[/tex] and [tex]y[/tex] are left as variables. [tex]x[/tex] and [tex]y[/tex] represent any given point in the function. In this case, one of the given coordinates is [tex](-8, 6)[/tex], and we can use this by using [tex]-8[/tex] as [tex]x[/tex] and [tex]6[/tex] as [tex]y[/tex]. After plugging in known variable, the equation becomes this:

[tex]6 = \frac{1}{4} ( - 8) + b[/tex]

This simplifies to:

[tex]6 = - 2 + b[/tex]

Then to:

[tex]4=b[/tex].

After plugging in slope and y-intercept, the finished equation is:

[tex]y = \frac{1}{4} x + 4[/tex]
