Answer:

1 3/8 Feet

Step-by-step explanation:

Take 2 1/2 and subtract 1 1/8 which gives u 1 3/8

if u don't understand fractions u can always turn ur fractions into decimals that's what I did :)

Answer:

It's A

Step-by-step explanation:

Using process of elimination B is wrong because even though you get 37 and 36 it multiplies them because of a lack of addition symbol. C is also wrong because it would turn out to be 12 x 13 which is larger than C so that's not it. in D 3x4 is 12 but it's added to 9 not multiplied so that's wrong which leaves you with A which is 9(3 + 4) = 63 and 27 + 36 = 63

We have to find derivative of t

[tex]\\ \sf\longmapsto \dfrac{d}{dx}3t^2-12t+4[/tex]

[tex]\boxed{\sf \dfrac{d(x^n)}{dx}=nx^{n-1}}[/tex]

[tex]\\ \sf\longmapsto \dfrac{d}{dx}3t^2-\dfrac{d}{dx}12t+\dfrac{d}{dx}40[/tex]

[tex]\\ \sf\longmapsto 6t-12[/tex]

Now

[tex]\\ \sf\longmapsto 6(8)-12[/tex]

[tex]\\ \sf\longmapsto 48-12[/tex]

[tex]\\ \sf\longmapsto 36[/tex]

Answer:

the area!!!

Step-by-step explanation:

2(a+b)h

to find b you have to know the base of the triangle. you may use pythagoras' theorem for that. you will then get 5ft as the base.

5ft + 48ft = 53ft.

put in the formula, the area is then

2(48+53)*13

am not with a calculator.... so sort it out....

I think you can get the rest with this...

Answer:

Slope intercept is y = mx+b.

SLOPE is m

and Y-INTERCEPt, where the thing touches the y axis is b.

The line touches the y axis at -6.

The slope is 2/3

y=2/3x-6

Answer:

Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values.

Step-by-step explanation:

To find the perimeter of a rectangle, you add up 2 times the length and 2 times the width. Here's the expression: [tex]2l+2w[/tex]. In this case l=22 or l=27.7 and w=27.7 or w=22. In the end, you get: [tex]2l+2w=99.4[/tex]. [tex]22*2=44. \\27.7*2=55.4[/tex].

To find the area of a rectangle, you multiply the length by the width. Here's the expression: [tex]lw[/tex].  In this case l=22 or l=27.7 and w=27.7 or w=22. In the end, you get: [tex]22*27.7=609.4[/tex].

Side note:

It doesn't matter what l or w equal because There's a property in addition that says it doesn't matter which order the values go in. There's also a property in multiplication that it doesn't matter which order the values go in (same as addition).

Answer:

x = 6

y = - 3

Step-by-step explanation:

x * y = - 18

x - y = 9. 3-y-y = 9. 3 -2y = 9.

-2y = 9-3

y = 6/-2

y = -3

x + y = 3. x = 3-y

x * -3 = - 18

x = -18/-3

x = 6

3*m=42

Step-by-step explanation:

equation: 3m=42

Answer:

42=m3

Step-by-step explanation:

Product means like, multiplication of the numbers or values

Answer:

m = -1

Step-by-step explanation:

Find the equation in slope intercept form [ y = mx + b ] for line AB. Find the slope using the formula [ y2-y1/x2-x1 ].

8-5/7-4

3/3

1

Find the y-intercept.

5 = 1(4) + b

5 = 4 + b

1 = b

So the equation of the line AB is y = x + 1.

The slope of a perpendicular line is the opposite reciprocal of the original line.

1 -> -1/1 -> -1

Answer:

30°

Step-by-step explanation:

A full circle has 360°.

1/12 of a circle has 1/12 of 360°.

1/12 * 360° = 360°/12 = 30°

Answer: 30°

Answer: Distance upstream = (34-c)(39/60) miles

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

Distance downstream = (34+c)(29/60) miles

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

Equation:

distance = rate*time

distance up = distance down

(34-c)(39/60) = (34+c)(29/60)

Multiply both sides by 60 to get:

39(34-c) = 29(34+c)

39*34 - 39c = 29*34 + 29c

68c = 340

Answer:

[tex]g( - 8) = - 2( - 8) - 5 = 16 - 5 = 11[/tex]

[tex]f(g( - 8)) = {11}^{2} + 1 \\ = 121 + 1 \\ = 122[/tex]

I hope I helped you^_^

[tex]\\ \sf\longmapsto g(x)=-2x-5[/tex]

[tex]\\ \sf\longmapsto g(-8)[/tex]

[tex]\\ \sf\longmapsto -2(-8)-5[/tex]

[tex]\\ \sf\longmapsto 16-5[/tex]

[tex]\\ \sf\longmapsto 11[/tex]

The height of the window is 9-x feet.

Given that, a window is 9 ft long. It is x feet longer than it is high.

We need to find what is the height of the window.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Here, the length of the window = 9 ft

Then, the height of the window = x feet smaller than the length = 9-x feet

Therefore, the height of the window is 9-x feet.
