a. 4/25
b. 1/3
c. 7/25
d. 4/21

Answer:

The slope of line passes (x1, y1) and (x2, y2) could be calculated by:

    slope = (y2 - y1)/(x2 - x1)

=>A line passes (5, 1) and (2, -2) has the slope:

    slope = (-2 - 1)/(2 - 5) = (-3)/(-3) = 1

Hope this helps!

We know that [tex]A=hl[/tex]. Given [tex]A[/tex] and [tex]h[/tex] we can find [tex]l[/tex].

How? Well here is a procedure.

[tex]

A=hl \\

\frac{A}{h} = \frac{hl}{h} \\

\frac{A}{h} = l \\

l=\frac{200}{25}=\boxed{8\mathrm{in}}

Hope this helps.

Answer:

17 units

Step-by-step explanation:

The midsegment of a triangle theorem states that:

The midsegment is 1/2 of it's parallel side.

So,

6x + 5 = 1/2(4x + 26)

6x + 5 = 2x + 13

6x - 2x + 5 = 13

4x + 5 = 13

4x = 13 - 5

4x = 8

x = 8 ÷ 4

x = 2

Substitute x to the midsegment.

6x + 5

6(2) + 5

12 + 5

17

Hello

Here is the answer:

A midsegment of a triangle is a segment connecting the midpoints of two sides of a triangle.  It is always parallel to the third side, and the length of the midsegment is half the length of the third side.

It is A again.

Step-by-step explanation:

Equation given:

[tex]F=kx-kx_{0}[/tex]

We have to isolate [tex]x[/tex]

[tex]F+kx_{0}=kx[/tex]

Divide both sides by [tex]k[/tex]

[tex]$\frac{F+k_{0}}{k}=x$[/tex]

Answer:

x=9

Step-by-step explanation:

2x+3(6)=36

2x+18=36

2x=18

x=9

Answer:

x=9

Step-by-step explanation:

if y=6 its now 2x + 18 =36. Subtract 18 from both sides. 2x = 18. 2(9) = 18. Therefore x=9

Answer:

Polyester Fabric = 4 || 8 || 16 || 22

Silk Fabric          = 18 || 36 || 72 || 99

Step-by-step explanation:

Given:

The above table

Ratio; Polyester Fabric : Silk = 2:9

Required

Complete the above table

Provided that the ratio of the cost of one meter of polyester fabric to the cost of one meter of one silk is 2:9;

To complete rows of polyester fabric

We simply multiply cost by ratio of polyester fabric ratio (2)

To complete rows of silk fabric

We simply multiply cost by ratio of silk fabric ratio (9)

This is as follows:

When length = 2m

Polyester Fabric = 2 * 2 = 4

Silk Fabric = 2 * 9 = 18

When length = 4m

Polyester Fabric = 4 * 2 = 8

Silk Fabric = 4 * 9 = 36

When length = 8m

Polyester Fabric = 8 * 2 = 16

Silk Fabric = 8 * 9 = 72

When length = 11m

Polyester Fabric = 11 * 2 = 22

Silk Fabric = 11 * 9 = 99

Hence, the complete table is as follows:

Polyester Fabric = 4 || 8 || 16 || 22

Silk Fabric          = 18 || 36 || 72 || 99

Answer:

1.2

Step-by-step explanation:

She bought 1.2 bitcoins in $400.

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that,

Number of bitcoins in $1 USD =  0.003

The to find the number of bitcoins in $400

We just multiply 400 by the number of bitcoin bought in 1 $1 USD

Therefore,

The number of bitcoin she bought in $400 is,

= 400 x 0.003

= 1.2

Thus,

Number of bitcoins in $400 = 1.2

Answer:

(8, -1)

Step-by-step explanation:

To use elimination, we can add the two equations together to eliminate the y:

x-y = 9

x+y = 7

x + x -y + y = 16

2x = 16

x = 8

Plug that back into the original equation to get:

8-y = 9

y = -1

So the ordered pair is (8, -1)

Answer:

c.) quadratic binomial

Step-by-step explanation:

Quadratic equation:

ax² + bx + c

The polynomial is in this form and like all quadratics forms a parabola, a u-shape, when graphed. Therefore, it is a quadratic equation.

Binomial = an expression with two terms

This polynomial has three terms: x², and 5x, making it a quadratic binomial.

Answer:

B

Step-by-step explanation:

Subtitution method:

y=6x-4 (1)

y=7x-7 (2)

subtitute 7x-7 into (1) because both y1 and y2 are same

7x-7=6x-4

7x-6x=-4+7

x=3

subtitute x=3 into any equation

eg: y=6x-4 y=7x-7

=6(3)-4 or =7(3)-7

=14 =14

Answer:

c

Step-by-step explanation:

you know what output you get from the input.

For example, you know that if you put in -5, you get -2, or if you put in 4, you get -2.

Even though there are two inputs for one output, it is still a function.

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

If there are two outputs for one input, it is not a function.

For example, on d, when -5 is an input, you don't know if you're going to get 3 or 7. So, it's not a function.

Answer:

Because the product is always non-termination,non-repeating decimal.

Step-by-step explanation:

If we have [tex]a[/tex] is irrational;  [tex]b[/tex] is rational such that [tex]b \neq 0[/tex] , then [tex]a \cdot b[/tex] is irrational.

A way to represent this is:

[tex]a\in\mathbb{R}\setminus\mathbb{Q}, b\in\mathbb{Q},ab\in\mathbb{Q}\implies a\in\mathbb{Q}\implies\text{Contradiction}\therefore ab\not\in\mathbb{Q}.[/tex]

Note that we have a contradiction, because [tex]a[/tex] is not a rational number, as I stated in the beginning. Therefore, ab is irrational.

Answer: A

Step-by-step explanation:

Multiplying an irrational number by a rational number will always be an irrational number because irrational numbers do not repeat and terminate.

So for example multiplying pi by a rational like two you will have an irrational number because pi is an irrational number.

[tex]\pi * 2[/tex] = 6.28318530718  as you could see that is an irrational number because there is no repetition or termination.

Answer:

h = 39.8 inches

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2h

We know the diameter d = 32 so the radius is 1/2 of the diameter

r = d/2=32/2 = 16

32000 = pi (16)^2 h

32000 = 256 ( pi) h

Divide each side by 256 pi

32000 / 256 pi = h

125/pi = h

Using 3.14 for pi

39.8089172 = h

Rounding to the nearest tenth

h = 39.8 inches

C.440.24

Step-by-step explanation:

To get the new balance first multiply the extra balance

[tex]\frac{2.5}{100}*429.50[/tex]

[tex]\frac{1073.75}{100}[/tex]

[tex]10.7375[/tex]

so add the new balance to 429.50

429.50+10.7375=440.2375=440.24

Answer:

C. $440.24

Step-by-step explanation:

Multiply 0.025 (the decimal form of 2.5%) to 429.50:

429.50 · 0.025 = 10.7375

Then add the sum to the original balance:

429.50 + 10.7375 = 440.2375

Round to nearest hundredth:

440.24
