3w + 7 - 9w help me answer !

Answer:

C) 352 cm^2

Step-by-step explanation:

[tex]We\ are\ given\ that\ ,\\Volume\ of\ the\ cylindrical\ vessel = 448\pi\ cm^3\\Height\ of\ the\ cylindrical\ vessel =7 cm\\\\We\ know\ that,\\Volume\ of\ a\ cylinder=\pi r^2h\\Hence,\\\pi r^2h=448\pi \\Substituting\ 7\ instead\ of\ h,\ we\ get,\\\pi r^2*7=448\pi \\Canceling\ \pi \ on\ both\ the\ sides\ we\ have,\\r^2*7=448\\r^2=448/7\\r^2=64\\r=8[/tex]

[tex]We\ now\ know\ that\ ,\\Radius\ of\ cylindrical\ vessel\ = 8\\Height\ of\ the\ cylindrical\ vessel\ =7\\\\Hence,\\CSA\ of\ a\ cylinder\ = 2\pi rh\\CSA\ of\ the\ cylindrical\ vessel = 2*\pi *7*8\\Approxiamating\ the\ value\ of\ \pi\ as\ \frac{22}{7} ,\\CSA\ of\ the\ cylindrical\ vessel = 2*\ \frac{22}{7} *7*8\\=2*22*8\\=352\ cm^2[/tex]

Answer:

the width is 8 inches

Step-by-step explanation:

area=length x width

88=11(w)

w=8

Answer:

8

Step-by-step explanation:

A flyer is the shape of a rectangle ad its area uses the formula A = l*w. Since the area is 88 and the length is 11 inches, then 88 = 11*w. Solve for w.

88/11 = 11w/11

8=w

Answer:

Required indicated angle is: 47°

Step-by-step explanation:

Given triangle is a right angled triangle

The side opposite to reference angle is perpendicular so,

Hypotenuse = 48

Perpendicular = 35

The trigonometric ratio of sine will be used as it involves hypotenuse and perpendicular.

Let y be the required angle

[tex]sin\ y = \frac{perpendicular}{hypotenuse}\\sin\ y = \frac{35}{48}\\sin\ y = 0.72916\\y = sin^{-1}\ (0.72916)\\y = 46.81..[/tex]

Rounding off to nearest degree,

y = 47°

Hence,

Required indicated angle is: 47°

Answer:

(2, 1)

Step-by-step explanation:

The solution is the point where the two lines intersect. In this case, that is (2, 1)

Answer:

when f(x) is -1, f(x) =  -3

when f(x) is 0, f(x) = 1

when f(x) is 3, f(x)= 13

so is -3, 1 and 13.

you basically replace  x with the number and then evaluate

hope is helpful!!

Answer:

13º

Step-by-step explanation:

We know a straight line makes 180, so the one opposite 63 is (180-63) which is 117.

We know the interior angles in a triangle make 180. We know two angles 50 and 117 and 50+117=167. 180-167=13.

Answer:

Bisect angle split an angle equally.

So,

ABD = DBC

2x+5 = x + 23

x = 23 - 5

x = 18

Answer:

x = 150

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

Sum the given interior angles and equate to 720, that is

130 + 90 + 120 + 112 + 118 + x = 720, simplifying

570 + x = 720 ( subtract 570 from both sides )

x = 150

Answer:

x=-2

Step-by-step explanation:

add 5 to get rid of the -5 and then -4 become 1 then multiply by 10 to get rid of the divide by 10 then 10 times 1 equals 10 so then you divide by negative 5 so now you have x=10÷-5 and that equals -2

Given :

The ordered pair (10, 4) is solution to the equation 3x - 5y = 10.

To Find :

Which one is the solution and which is not.

Solution :

Two pairs are (10,4) and (4,10) :

Putting ( 10,4 ) in given equation, we get :

LHS = 3( 10 ) - 5( 4 ) = 30 - 20 = 10 = RHS

So, ( 10,4 ) is the solution of the equation.

Now, putting, ( 4, 10 ) in given equation, we get :

LHS = 3( 4 ) - 5( 10 ) = 12 - 50 = -38 ≠ RHS

Therefore, (10,4) is the solution and (4,10 ) is not the solution.

Hence, this is the required solution.

Answer: Yes, (10,4) is a solution
